    Merila, P.; Derome, J.; Lindgren, M.

    2007-12-01

    Finland has been participating in the ICP Forests programme (the International Co-operative Programme on the Assessment and Monitoring of Air Pollution Effects on Forests) based on international agreements on the long- range transportation of air pollutants (LRTAP) and other associated monitoring programmes (e.g. Forest Focus, ICP Integrated Monitoring, ICP Vegetation) since 1985. The knowledge gained during the years has greatly increased our understanding of the overall condition of our forests and the factors affecting forest condition, the processes underlying forest ecosystem functioning, and the potential threats to our forests posed by human activities, both at home and abroad. The success of the monitoring activities in Finland is largely based on the experience gained during the early 1980's with our own national acidification project and, during the late 1980's and early 1990"s, in a number of regional monitoring projects. Finland's membership of the European Union (entry in 1996) has enabled us to further develop the infrastructure and coverage of both our extensive and intensive level networks. This broadening of our ecological understanding and development of international collaboration are now providing us with an invaluable basis for addressing the new monitoring challenges (biodiversity, climate change). The results gained in our monitoring activities clearly demonstrate the value of long-term monitoring programmes. The main results have been regularly reported both at the European (e.g. http://www.icp- forests.org/Reports.htm) and national level (e.g. http://www.metla.fi/julkaisut/workingpapers/2007/mwp045- en.htm). However, the datasets have not been intensively explored and exploited, and few of the important methodological and ecological findings have been published in peer-reviewed scientific journals. This has, understandably, not been the first priority of the international monitoring programmes. A number of the intensive forest monitoring plots in Finland have recently been included in LTER platforms, thus potentially increasing scientific collaboration between researchers across different governmental institutes and education bodies.

  3. Effects of biomass utilization on the carbon balance of Finnish forests

    The boreal forests cover three fourths of the land area of Finland. About 80 per cent of the total forest area is managed for commercial forestry. The forests produce timber for wood processing and pulp and paper industries and provide also bioenergy. The harvests of timber vary depending on demand of products of forest industry; the harvest level has been on average about 70 per cent of growth in recent years. The utilization of forest biomass is therefore the most important factor affecting the carbon balance of Finnish forests. We made projections of carbon balance of Finnish forests during 2012-2050 based on scenarios of timber and bioenergy demands. To assess the changes in carbon stock of forests, we combined three models: a large-scale forestry model, the soil carbon model Yasso07 for mineral soils, and a method based on emission factors for peatland soils. We considered two harvest scenarios based on the recent projections of plausible levels (min, max) of timber demand. For the bioenergy demand, we compared cases in which the wood energy use was low or high. In the past decades, the Finnish forests have been a steadily growing and substantial carbon sink. Its size has been more than 40% of the national GHG emissions during 1990-2012. The planned use of wood from the forests to forest and energy industry does not threaten the increasing trend of the forest sink; with the lowest use of forest biomass the sink may even match the national GHG emissions until 2050. The stock change of trees is the most important component of carbon balance of forests; it accounts for approximately 80 % of the total stock change. Trees and mineral soils act as carbon sinks and the drained peatland soils as a carbon source. By comparing the scenarios of wood energy use we conclude that the amount of carbon emissions avoided by replacing fossil fuels with stemwood is outweighed by the loss in carbon sequestration.

  5. Finnish nurses' attitudes towards nursing research and related factors.

    Kuuppelomäki, Merja; Tuomi, Jouni

    2005-02-01

    This study was concerned with Finnish nurses' attitudes to nursing research and with the associations of different background factors with these attitudes. The data were collected with a purpose-designed, structured questionnaire. The study was carried out in one central hospital, one central university hospital and 10 community health centres in Finland. A total of 400 nurses took part. The response rate was 67%. The data were analysed using SPSS statistical software. Attitudes to nursing research were generally quite positive, although over half of the nurses felt their own relationship to nursing science was quite distant. There were also shortfalls with respect to the information value and utilisation of research results. Only one-third took the view that doing research is an important part of the nurse's job. Age, the frequency of reading the professional literature, participation in training courses, training received in research and development, and the type of workplace were associated with attitudes. The results underline the importance of paying closer attention to the choice of research objects in the field of nursing science. Greater effort should also be invested in supporting and developing the application of research results. It is recommended that more courses on research methodology and other relevant training be made available to practical nurses. PMID:15680617

  10. Applying a framework for landscape planning under climate change for the conservation of biodiversity in the Finnish boreal forest.

    Conservation strategies are often established without consideration of the impact of climate change. However, this impact is expected to threaten species and ecosystem persistence and to have dramatic effects towards the end of the 21st century. Landscape suitability for species under climate change is determined by several interacting factors including dispersal and human land use. Designing effective conservation strategies at regional scales to improve landscape suitability requires measuring the vulnerabilities of specific regions to climate change and determining their conservation capacities. Although methods for defining vulnerability categories are available, methods for doing this in a systematic, cost-effective way have not been identified. Here, we use an ecosystem model to define the potential resilience of the Finnish forest landscape by relating its current conservation capacity to its vulnerability to climate change. In applying this framework, we take into account the responses to climate change of a broad range of red-listed species with different niche requirements. This framework allowed us to identify four categories in which representation in the landscape varies among three IPCC emission scenarios (B1, low; A1B, intermediate; A2, high emissions): (i) susceptible (B1 = 24.7%, A1B = 26.4%, A2 = 26.2%), the most intact forest landscapes vulnerable to climate change, requiring management for heterogeneity and resilience; (ii) resilient (B1 = 2.2%, A1B = 0.5%, A2 = 0.6%), intact areas with low vulnerability that represent potential climate refugia and require conservation capacity maintenance; (iii) resistant (B1 = 6.7%, A1B = 0.8%, A2 = 1.1%), landscapes with low current conservation capacity and low vulnerability that are suitable for restoration projects; (iv) sensitive (B1 = 66.4%, A1B = 72.3%, A2 = 72.0%), low conservation capacity landscapes that are vulnerable and for which alternative conservation measures are required depending on the intensity of climate change. Our results indicate that the Finnish landscape is likely to be dominated by a very high proportion of sensitive and susceptible forest patches, thereby increasing uncertainty for landscape managers in the choice of conservation strategies.

    Controversy between alternative uses of forests in Finnish Upper Lapland has been going on for decades, and in recent years it has been escalated to a serious conflict. The core of the conflict is the adverse impacts of forestry on old forests which are important grazing areas for reindeer and which are regarded as intact nature and wilderness areas. This paper describes the experiences of applying multi-criteria decision analysis interview approach on this conflict. The approach provides tools for structuring the problem and preferences of the stakeholders as well as for analyzing the effects of different alternatives in a common framework. We focus on the practical experiences gained from the application of this approach in this context. Multi-criteria decision analysis was found to be a useful approach to evaluate the economic, ecological and cultural aspects of this intense conflict. The obtained experiences also support the view that the approach works best when tightly integrated into the planning process. PMID:21288630

  12. [Forest degradation/decline: research and practice].

    PubMed

    Zhu, Jiao-Jun; Li, Feng-Qin

    2007-07-01

    As one of the most critical environmental problems in the 21st century, forest degradation has been facing worldwide. There are many definitions about forest degradation, but its common features are the permanent loss of forests, stand structure destructed, forest quality decreased, and forest functions lowered. Forest decline or tree decline in fact is one of the causes of forest degradation, which includes the general reduction of trees in vigor, low level growth of trees in productivity, death of trees, and even, decline of soil fertility. Many researches indicated that deforestation is the permanent loss of forests in area, which is shifted to other land uses. Deforestation is the product of the interactions between environmental, social, economic, cultural, and political forces at work in any given country/region, and thus, more and more attention is focused on the negative socioeconomic and environmental effects after forest degradation, especially on the reduction of forest area induced by deforestation. The effects of any decisions or policies in national and international levels on forest degradation induced by deforestation have been paid attention as well. How to make efforts and strengthen the worldwide cooperation to combat the forest degradation induced by deforestation must be challenged to find appropriate solutions. There are many researches on forest decline, because of its complexity and uncertainties. The major causes of forest decline include: 1) pollution from both industry and agriculture, 2) stress factors, e.g., desiccation, 3) changes in stand dynamics, 4) decline disease of forest or diseases of complex etiology, 5) degradation of productivity and/or soil fertility in pure plantation forests. Forest degradation in China is similar to that all over the world, but with the characteristics in forest components, i.e., 1) secondary forests are the major forest resources, 2) China has the most plantation forests in the world, some of which have low qualities or functions. Based on the above reviews and perceptions on forest degradation and related practices, the main causes of contemporary forest degradation were summarized, and the general countermeasures for combating forest degradation/decline were given.

    Intensive atmospheric field measurement was held on at Tomakomai research forest during summer in 2006. The purpose of the measurement was to observe the atmospheric chemistry at enhanced biogenic emission area influenced by urban polluted air, especially in the view point of OH reactivity. Tomakomai research forest is located by city area. Several VOCs including both anthropogenic and biogenic VOC were observed by different methods, canister grab sampling (GC-FID, and GC-MS), on site GC-FID measurement, and PTR-MS measurement. Also general atmospheric species (O3, CO, NOx, SO2) were observed. From the results of anthropogenic species, influence of urban air nearby and of long-range transport was both expected. Also influence of volcano was expected by SO2. The comparison of biogenic VOCs by different methods showed good agreement. The problem during the canister storage was not observed. Observed terpenes (alfa-pinene, camphene, limonene, and beta-pinene) showed higher concentration during night and lower during daytime. The maximum concentration was about 900 ppt as the sum of terpenes. On the other hand, isoprene showed higher concentration during daytime and low during night. The maximum concentration was about 1.5 ppb. There concentrations were not high as expected as a forest atmosphere. Since the temperature during the campaign was 27 C at maximum, the emission from the plants was not very enhanced. The comparison with directly observed OH reactivity and calculated OH reactivity from various species showed some difference during daytime. The difference has good correlation between isoprene. The difference would be caused by unmeasured species, which should have similar concentration variation as isoprene. The signal of m/z=71 observed by PTR-MS, corresponding to VMK and MACR, showed quite similar variation of isoprene. They ware produced by the oxidation of isoprene. Even if their very high concentrations were assumed, the difference of the OH reactivity can not be explained.

  12. Biogeographical and taxonomic biases in tropical forest fragmentation research.

    2014-12-01

    Despite several decades of research on the effects of fragmentation and habitat change on biodiversity, there remain strong biases in the geographical regions and taxonomic species studied. The knowledge gaps resulting from these biases are of particular concern if the forests most threatened with modification are also those for which the effects of such change are most poorly understood. To quantify the nature and magnitude of such biases, we conducted a systematic review of the published literature on forest fragmentation in the tropics for the period 1980-2012. Studies included focused on any type of response of single species, communities, or assemblages of any taxonomic group to tropical forest fragmentation and on fragmentation-related changes to forests. Of the 853 studies we found in the SCOPUS database, 64% were conducted in the Neotropics, 13% in Asia, 10% in the Afrotropics, and 5% in Australasia. Thus, although the Afrotropics is subject to the highest rates of deforestation globally, it was the most disproportionately poorly studied biome. Significant taxonomic biases were identified. Of the taxonomic groups considered, herpetofauna was the least studied in the tropics, particularly in Africa. Research examining patterns of species distribution was by far the most common type (72%), and work focused on ecological processes (28%) was rare in all biomes, but particularly in the Afrotropics and for fauna. We suggest research efforts be directed toward less-studied biogeographic regions, particularly where the threat of forest fragmentation continues to be high. Increased research investment in the Afrotropics will be important to build knowledge of threats and inform responses in a region where almost no efforts to restore its fragmented landscapes have yet begun and forest protection is arguably most tenuous.

    Forest musk deer is one of the large-scale farming musk deer animals with the largest population at the same time. The male musk deer can secrete valuable medicines, which has high medicinal and economic value. Due to the loss of habitat and indiscriminate hunting, the numbers of wild population specie and the distribution have been drastically reduced. Therefore, in-depth understanding of the molecular genetics progress of forest musk deer will pave a way for musk deer protection and breeding. In this review, the progress associated with the molecular marker, genetic classification, artificial breeding, musk secretion and disease in past decades were reviewed, in order to provide a theoretical basis for subsequent molecular genetic researches in forest musk deer.

    2011-12-01

    With 207 million ha of forest covering 22% of its land area, China ranks fifth in the world in forest area. Rapid economic growth, climate change, and forest disturbances pose new, complex challenges for forest research and management. Progress in meeting these challenges is relevant beyond China, because China's forests represent 34% of Asia's forests and 5% of the worlds' forests. To provide a broader understanding of these management challenges and of research and policies that address them, we organized this special issue on contemporary forest research and management issues in China. At the national level, papers review major forest types and the evolution of sustainable forestry, the development of China's forest-certification efforts, the establishment of a forest inventory system, and achievements and challenges in insect pest control in China. Papers focused on Northern China address historical, social, and political factors that have shaped the region's forests; the use of forest landscape models to assess how forest management can achieve multiple objectives; and analysis and modeling of fuels and fire behavior. Papers addressing Central and South China describe the "Grain for Green" program, which converts low productivity cropland to grassland and woodland to address erosion and soil carbon sequestration; the potential effects of climate change on CO2 efflux and soil respiration; and relationships between climate and net primary productivity. China shares many forest management and research issues with other countries, but in other cases China's capacity to respond to forest management challenges is unique and bears watching by the rest of the world.

  16. Comparison of AVHRR classification and aerial photography interpretation for estimation of forest area. Forest Service research paper

    1995-09-01

    The USDA Forest Service Southern Forest Experiment Station`s Forest Inventory and Analysis (SO-FIA) unit uses a dot count method to estimate the percentage of forest area in counties or parishes from aerial photographs. The research reported in this paper was designed to determine whether Advanced Very High Resolution Radiometer (AVHRR) data could be used to estimate forest area at the county or parish level. For this study, AVHRR data for three parishes in central Louisiana were extracted from a 1991 AVHRR forest type map of the United States.

    Three-dimensional (3D) remote sensing has enabled detailed mapping of terrain and vegetation heights. Consequently, forest inventory attributes are estimated more and more using point clouds and normalized surface models. In practical applications, mainly airborne laser scanning (ALS) has been used in forest resource mapping. The current status is that ALS-based forest inventories are widespread, and the popularity of ALS has also raised interest toward alternative 3D techniques, including airborne and spaceborne techniques. Point clouds can be generated using photogrammetry, radargrammetry and interferometry. Airborne stereo imagery can be used in deriving photogrammetric point clouds, as very-high-resolution synthetic aperture radar (SAR) data are used in radargrammetry and interferometry. ALS is capable of mapping both the terrain and tree heights in mixed forest conditions, which is an advantage over aerial images or SAR data. However, in many jurisdictions, a detailed ALS-based digital terrain model is already available, and that enables linking photogrammetric or SAR-derived heights to heights above the ground. In other words, in forest conditions, the height of single trees, height of the canopy and/or density of the canopy can be measured and used in estimation of forest inventory attributes. In this paper, first we review experiences of the use of digital stereo imagery and spaceborne SAR in estimation of forest inventory attributes in Finland, and we compare techniques to ALS. In addition, we aim to present new implications based on our experiences.

    2011-12-01

    With 207 million ha of forest covering 22% of its land area, China ranks fifth in the world in forest area. Rapid economic growth, climate change, and forest disturbances pose new, complex challenges for forest research and management. Progress in meeting these challenges is relevant beyond China, because China's forests represent 34% of Asia's forests and 5% of the worlds' forests. To provide a broader understanding of these management challenges and of research and policies that address them, we organized this special issue on contemporary forest research and management issues in China. At the national level, papers review major forest types and the evolution of sustainable forestry, the development of China's forest-certification efforts, the establishment of a forest inventory system, and achievements and challenges in insect pest control in China. Papers focused on Northern China address historical, social, and political factors that have shaped the region's forests; the use of forest landscape models to assess how forest management can achieve multiple objectives; and analysis and modeling of fuels and fire behavior. Papers addressing Central and South China describe the "Grain for Green" program, which converts low productivity cropland to grassland and woodland to address erosion and soil carbon sequestration; the potential effects of climate change on CO(2) efflux and soil respiration; and relationships between climate and net primary productivity. China shares many forest management and research issues with other countries, but in other cases China's capacity to respond to forest management challenges is unique and bears watching by the rest of the world.

    Michigan`s Northern Lower Peninsula Unit (fig. 1) is comprised of 33 counties. This region of the State is rich with resources that support a network of social, economic, and ecological processes that are forest dependent. The forest resource of the Unit presently supports an industry that operates on a sustaining basis. In 1990 nearly half of Michigan`s saw-log production--297 million board feet--was harvest in the Unit. The forests of the Northern Lower Peninsula are vital to the region. The forest contains a variety of both deciduous and coniferous forest species, which results in regionally unique ecosystems that contribute to biodiversity.

    1984-01-01

    Per-pixel maximum likelihood digital classification and photo interpretation of Thematic Mapper Simulator (TMS) composited images for a managed conifer forest were used to evaluate both land cover and forest structure characteristics. TMS channels 4, 7, 5 and 3, which were found to be optimal for forest vegetation analysis, used the full range of the Thematic Mapper's spectral capability. Photo interpretation results indicate that a false color composite from TMS channels 4, 7, and 2 provided the highest accuracies; the combination of improved spatial, spectral and radiometric resolution of the Thematic Mapper yielded greater sensitivity to forest structural characteristics.

  10. An imperative need for global change research in tropical forests.

    PubMed

    Zhou, Xuhui; Fu, Yuling; Zhou, Lingyan; Li, Bo; Luo, Yiqi

    2013-09-01

    Tropical forests play a crucial role in regulating regional and global climate dynamics, and model projections suggest that rapid climate change may result in forest dieback or savannization. However, these predictions are largely based on results from leaf-level studies. How tropical forests respond and feedback to climate change is largely unknown at the ecosystem level. Several complementary approaches have been used to evaluate the effects of climate change on tropical forests, but the results are conflicting, largely due to confounding effects of multiple factors. Although altered precipitation and nitrogen deposition experiments have been conducted in tropical forests, large-scale warming and elevated carbon dioxide (CO2) manipulations are completely lacking, leaving many hypotheses and model predictions untested. Ecosystem-scale experiments to manipulate temperature and CO2 concentration individually or in combination are thus urgently needed to examine their main and interactive effects on tropical forests. Such experiments will provide indispensable data and help gain essential knowledge on biogeochemical, hydrological and biophysical responses and feedbacks of tropical forests to climate change. These datasets can also inform regional and global models for predicting future states of tropical forests and climate systems. The success of such large-scale experiments in natural tropical forests will require an international framework to coordinate collaboration so as to meet the challenges in cost, technological infrastructure and scientific endeavor.

    Since 1908, U.S. Forest Service Experimental Forests and Ranges have been dedicated to long-term interdisciplinary research on a variety of ecological and management questions. They encompass a wide diversity of life zones and ecoregions, and provide access to research infrastructure, opportunities for controlled manipulations, and integration with other types of long-term data. These features have facilitated important advances in a number of areas of avian research, including furthering our understanding of population dynamics, the effects of forest management on birds, avian responses to disturbances such as fire and hurricanes, and other aspects of avian ecology and conservation. However, despite these contributions, this invaluable resource has been underutilized by ornithologists. Most of the Experimental Forests and Ranges have had no ornithological work done on them. We encourage the ornithological community, especially graduate students and new faculty, to take advantage of this largely untapped potential for long-term work, linkage with long-term data sets, multiple disciplines, and active forest management. ?? 2010 Elsevier B.V.

    The study of the growth of nucleation-mode particles is important, as this prevents their loss through diffusion and allows them to reach sizes where they may become effective cloud condensation nuclei. Hyytiälä, a forested site in southern Finland, frequently experiences particle nucleation events during the spring and autumn, where particles first appear during the morning and continue to grow for several hours afterwards. As part of the QUEST 2 intensive field campaign during March and April 2003, an Aerodyne Aerosol Mass Spectrometer (AMS) was deployed alongside other aerosol instrumentation to study the particulate composition and dynamics of growth events and characterise the background aerosol. Despite the small mass concentrations, the AMS was able to distinguish the grown particles in the <100 nm regime several hours after an event and confirm that the particles were principally organic in composition. The AMS was also able to derive a mass spectral fingerprint for the organic species present, and found that it was consistent between events and independent of the mean particle diameter during non-polluted cases, implying the same species were also condensing onto the accumulation mode. The results were compared with those from offline analyses such as GC-MS and were consistent with the hypothesis that the main components were alkanes from plant waxes and the oxidation products of terpenes.

    1980-01-01

    As research tools for evaluating the effects of chronic air pollution stress, forest simulation models offer one means of integrating forest growth and development data with generalized indices of pollution stress. This approach permits consideration of both the competitive interactions of trees in the forest stand and the influences of the stage of stand development on sensitivity of component species. A review of forest growth models, including tree, stand, and gap models, is provided as a means of evaluating relative strengths, weaknesses, and limits of applicability of representative examples of each type. Data from recent simulations with a gap model of eastern deciduous forest responses to air pollution stress are presented to emphasize the potential importance of competition in modifying individual species' responses in a forest stand. Recent developments in dendroecology are discussed as a potential mechanism for model validation and extended application.

    Water quality from forested landscapes tends to be very high but can deteriorate during and after silvicultural activities. Practices such as forest harvesting, site preparation, road construction/use, and stream crossings have been shown to contribute sediment, nutrients, and other pollutants to adjacent streams. Although advances in forest management accompanied with Best Management Practices (BMPs) have been very effective at reducing water quality impacts from forest operations, projected increases in demand for forest products may result in unintended environmental degradation. Through a review of the pertinent literature, we identified several research gaps related to water yield, aquatic habitat, sediment source and delivery, and BMP effectiveness that should be addressed for streams in the United States to better understand and address the environmental ramifications of current and future levels of timber production. We explored the current understanding of these topics based on relevant literature and the possible implications of increased demand for forest products in the United States.

    Recommendations for managing coarse woody debris after timber harvest were developed for 14 habitat types, ranging from ponderosa pine (Pinus ponderosa) habitat types of Arizona to subalpine fir (Abis lasiocarpa) habitat types of western Montana. Ectomycorrhizae were used as a bioindicator of health, productive forest soils. Undisturbed stands were studied to determine the optimum amounts of organic material for ectomycorrhizal activity. The management recommendations are intentionally conservative to ensure that enough organic matter is left after timber harvest to maintain long-term forest productivity.

    This study aims at conducting the first science mapping analysis of the Mediterranean forest research in order to elucidate its research structure and evolution. We applied a science mapping approach based on co-term and citation analyses to a set of scientific publications retrieved from the Elsevier’s Scopus database over the period 1980–2014. The Scopus search retrieved 2,698 research papers and reviews published by 159 peer-reviewed journals. The total number of publications was around 1% (N = 17) during the period 1980–1989 and they reached 3% (N = 69) in the time slice 1990–1994. Since 1995, the number of publications increased exponentially, thus reaching 55% (N = 1,476) during the period 2010–2014. Within the thirty-four years considered, the retrieved publications were published by 88 countries. Among them, Spain was the most productive country, publishing 44% (N = 1,178) of total publications followed by Italy (18%, N = 482) and France (12%, N = 336). These countries also host the ten most productive scientific institutions in terms of number of publications in Mediterranean forest subjects. Forest Ecology and Management and Annals of Forest Science were the most active journals in publishing research in Mediterranean forest. During the period 1980–1994, the research topics were poorly characterized, but they become better defined during the time slice 1995–1999. Since 2000s, the clusters become well defined by research topics. Current status of Mediterranean forest research (20092014) was represented by four clusters, in which different research topics such as biodiversity and conservation, land-use and degradation, climate change effects on ecophysiological responses and soil were identified. Basic research in Mediterranean forest ecosystems is mainly conducted by ecophysiological research. Applied research was mainly represented by land-use and degradation, biodiversity and conservation and fire research topics. The citation analyses revealed highly cited terms in the Mediterranean forest research as they were represented by fire, biodiversity, carbon sequestration, climate change and global warming. Finally, our analysis also revealed the multidisciplinary role of climate change research. This study provides a first holistic view of the Mediterranean forest research that could be useful for researchers and policy makers as they may evaluate and analyze its historical evolution, as well as its structure and scientific production. We concluded that Mediterranean forest research represents an active scientific field. PMID:27158823

    Since 1907 research and education have been the mission of the Harvard Forest is one of the oldest and most intensively studied forests in North America. Located in Petersham, Massachusetts, its 3000 acres of land have been a center of research and education since 1907. The Long Term Ecological Research (LTER) program, established in 1988 and funded by the National Science Foundation, provides a framework for much of this activity. An understanding of forest responses to natural and human disturbance and environmental change over broad spatial and temporal scales pulls together research topics including biodiversity studies, the effects of invasive organisms, large experiments and permanent plot studies, historical and retrospective studies, soil nutrient dynamics, and plant population and community ecological interactions. Major research in forest-atmosphere exchange, hydrology, and regional studies places the work in regional and global context, aided by modeling tools. Conservation and management research and linkages to policy have been part of the Forest since its beginning, and the approaches used in New England can often apply to international studies. [Copied from http://harvardforest.fas.harvard.edu/research.html] In addition to more than 150 datasets, the Visual Information Access system at Harvard University Library makes nearly 900 images pertaining to Harvard Forest research available online to the public.

    The Upland forests of Micronesia and American Samoa can provide many social, ecological, and esthetic benefits for island inhabitants. Substantial upland areas (the majority of acreage on some islands) are now occupied by secondary and grassland/savanna vegetation: such areas represent opportunities for restoration, with both native forest cover and plantations of introduced species. The review briefly describes characteristics of the islands and the nature of existing and potential upland forests, including the most common upland tree species. Principal information needs and research opportunities are discussed for 10 subjects: watershed rehabilitation, forest restoration in secondary vegetation areas, basic ecology, soils and nutrient relationships, damaging agents, forest inventory and productivity assessment, silvicultural systems, valuation of forest products and services, threatened and endangered species, and description and protection of native forest habitats.

  13. Passive nighttime warming facility for forest ecosystem research.

    A nighttime warming experiment is proposed. Over the last four decades a significant rise in nighttime minimum temperature has been determined from analysis of meteorological records from a global distribution of locations. The experiment involves nighttime deployment of infrared (IR) reflecting curtains around four sides of a forest canopy and across the top of the forest to mimic the top-down warming effect of cloud cover. The curtains are deployed with cable and pulley systems mounted on a tower and scaffolding structure built around the selected forest site. The trunk space is not enclosed except as an optional manipulation. The curtains reflect long-wave radiation emitted from the forest and ground back into the forest warming the trees, litter, and soil. Excellent infrared reflection can be obtained with commercially available fabrics that have aluminum foil bonded to one side. A canopy warming of 3 to 5 degrees C is expected on cloudless nights, and on cloudy nights, a warming of 1 to 3 degrees C is anticipated relative to a control plot. The curtains are withdrawn by computer control during the day and also at night during periods with precipitation or excessive wind. Examples of hypothesized ecosystem responses to nighttime warming include: (1) increase in tree maintenance respiration (decreasing carbon reserves and ultimately tree growth), (2) increase in the length of the growing season (increasing growth), (3) increase in soil respiration, (4) increase in litter decomposition, (5) increase in mineralization of N and other nutrients from soil organic matter, (6) increase in nutrient uptake (increasing growth), and (7) increase in N immobilization in litter. Hypothesis 1 has the opposite consequence for tree growth to Hypotheses 2 and 6, and thus opposite consequences for the feedback regulation that vegetation has on net greenhouse gas releases to the atmosphere. If Hypothesis 1 is dominant, warming could lead to more warming from the additional CO(2) emissions. Site-specific meteorological, ecophysiological, and phenological measurements are obtained in the warming treatment and in a carefully selected control plot to investigate site-specific hypotheses. Measurements made on both plots for a baseline period and during the period of curtain deployment provide data to test the hypotheses statistically by the "before-after-control-impact" method applicable to unreplicated experiments. The enclosure has a modular design that can be adapted and combined with other forest-scale manipulation experiments such as free air CO(2) enrichment and throughfall displacement. PMID:12651350

    Memory diseases are the most important determinant of health care service use and quality of life among older individuals. Adverse effects of medication are common among older people, but this age group is underrepresented in clinical trials. Finnish statutory health care and prescription registers, together with personal identification numbers (PINs) and a tax-supported public health plan covering all citizens provide excellent opportunities for epidemiological research. We used routinely collected data from the Finnish health care system to establish the Medication use among persons with Alzheimer’s disease (MedAlz-2005) cohort. This cohort study will be used to assess medication use and its effects on health status and hospitalization among persons with Alzheimer’s disease (Ad). The cohort includes all community-dwelling persons who had a clinically verified diagnosis of Ad, resided in Finland, and were alive on December 31, 2005 and a matched comparison person for each affected individual. data on purchased prescription medicines (1995–2009), inpatient hospital admissions (1972–2009), outpatient visits (1995–2009), details on diagnosed cancers (1972–2009), and mortality (until October 2010) are available for the whole cohort. This paper describes how this data can be utilized in etiological research and the assessment of health care service use, drug utilization, and associated adverse outcomes in a particularly vulnerable group that is often underrepresented in clinical trials.

    Catastrophes and manipulation of stocking levels are primary determinants of stand development and the appearance of future forest landscapes. Managers need stocking level guides particularly for sites incapable of supporting stocking levels presented in normal yield tables. To take advantage of information currently available the authors used some assumptions to relate growth basal area (GBA) to stand density index (SDI) and then create stocking level curves for use in northeastern Oregon and southeastern Washington. Use of these curves cannot be expected to eliminate all insect and disease problems, but the impact of mountain pine beetle should be moderated.

    The public Finnish social and health care system has been challenged by the economic crisis, administrative reforms and increased demands. Better integration as a solution includes many examples, which have been taken to use. The most important are the rewritten national and municipals strategies and quality recommendations, where the different sectors and the levels of care are seen as one entity. Many reorganisations have taken place, both nationally and locally, and welfare clusters have been established. The best examples of integrated care are the forms of teamwork, care management, emphasis on non-institutional care and the information technology. PMID:16896395

    Bibliometric is increasingly used for the analysis of discipline dynamics and management related decision-making. This study analyzes 937,923 keywords from 78,986 articles concerning forest ecology and conducts a serial analysis of these articles' characteristics. The articles' records, published between 2002 and 2011, were downloaded from the Web of Science, and their keywords were exported by Java processing programs. The result shows that forest ecology studies focused on forest diversity, conservation, dynamics and vegetation in the last decade. Developed countries, such as the USA, Canada, and Germany, were the most productive countries in the field of forest ecology research. From 2002 to 2011, the number of articles published annually related to forest ecology grew at a stable rate, as indicated by the fit produced by a high determination coefficient (R(2) = 0.9955). The findings of this study may be applicable for planning and managing forest ecology research and partners involved in such research may use this study as a reference. PMID:23687631

    United States forests and wood products have been a significant and persistent carbon sink of 100-200 million tons annually since 1950, currently offsetting about 12% of U.S. emissions of CO2. This carbon sink is caused by recovery of forest C stocks following timber harvest and abandonment of agricultural land over the last 150 years, and more recently the growth-enhancing effects of N deposition, increasing atmospheric CO2, and climate variability. The forest carbon sink would have been significantly larger if not for continued losses of forest to other land uses such as urban development, and increasing impacts from natural disturbances such as fire and insect outbreaks. Projections of the future U.S. C sink have raised concerns that it may disappear in a few decades because of slower growth, continued losses of forest area, and increasing demand for timber products especially bioenergy. However, continuing atmospheric and climate changes may delay this projected decline in the sink strength for another 50 years or longer. Research is urgently needed to improve projections of land-use changes and demand for timber, quantify the large-scale effects of atmospheric change and climate variability, and develop modeling approaches that can effectively integrate these multiple factors. Policy decisions to meet emissions reduction targets are partially dependent on assumptions about the magnitude of the future forest carbon sink; therefore, it is important to have convincing projections about how these various driving factors will affect forests in the future.

    Nitrogen (N) availability plays multiple roles in the boreal landscape, as a limiting nutrient to forest growth, determinant of terrestrial biodiversity, and agent of eutrophication in aquatic ecosystems. We review existing research on forest N dynamics in northern landscapes and address the effects of management and environmental change on internal cycling and export. Current research foci include resolving the nutritional importance of different N forms to trees and establishing how tree-mycorrhizal relationships influence N limitation. In addition, understanding how forest responses to external N inputs are mediated by above- and belowground ecosystem compartments remains an important challenge. Finally, forestry generates a mosaic of successional patches in managed forest landscapes, with differing levels of N input, biological demand, and hydrological loss. The balance among these processes influences the temporal patterns of stream water chemistry and the long-term viability of forest growth. Ultimately, managing forests to keep pace with increasing demands for biomass production, while minimizing environmental degradation, will require multi-scale and interdisciplinary perspectives on landscape N dynamics.

    Finnish astronomy publishing provides us with an interesting data sample. It is small but not too small: approximately one thousand articles have been published in a decade. There are only four astronomy institutes to be compared. An interesting paradox also emerges in the field: while Finnish science assessments usually value highly the impact of scientific publishing, no serious evaluations using real bibliometric data have been made. To remedy this, a comprehensive ten-year database of refereed papers was collected and analyzed.

    Air pollution, bulk precipitation, throughfall, soil condition, foliar nutrients, as well as forest health and growth were studied in 2006-2009 in a long-term ecological research (LTER) network in the Bucegi Mountains, Romania. Ozone (O(3)) was high indicating a potential for phytotoxicity. Ammonia (NH(3)) concentrations rose to levels that could contribute to deposition of nutritional nitrogen (N) and could affect biodiversity changes. Higher that 50% contribution of acidic rain (pH < 5.5) contributed to increased acidity of forest soils. Foliar N concentrations for Norway spruce (Picea abies), Silver fir (Abies alba), Scots pine (Pinus sylvestris), and European beech (Fagus sylvatica) were normal, phosphorus (P) was high, while those of potassium (K), magnesium (Mg), and especially of manganese (Mn) were significantly below the typical European or Carpathian region levels. The observed nutritional imbalance could have negative effects on forest trees. Health of forests was moderately affected, with damaged trees (crown defoliation >25%) higher than 30%. The observed crown damage was accompanied by the annual volume losses for the entire research forest area up to 25.4%. High diversity and evenness specific to the stand type's structures and local climate conditions were observed within the herbaceous layer, indicating that biodiversity of the vascular plant communities was not compromised.

    2009-08-01

    Researchers dealing with conservation subjects usually do not put the results of their work into practice, even when the primary purpose of their research is the preservation of biodiversity. In the South American temperate forests we identified an area with the highest genetic diversity in Argentina of Nothofagus nervosa, one of the most relevant southern beech species. Based on the information of our scientific study and our recommendations, the authorities of Lanin National Park changed the protection status of this area to avoid logging. The new forestry management plans include consideration of "high genetic diversity" in decisions on where logging will be allowed. Results of our initial genetic study induced the analysis of biodiversity at the species and ecosystems levels, which yielded results similar to our genetic studies. A strong connection among researchers and managers from the onset of our study and the awareness of the former about the importance of the implementation of the research work were key to bridging the gap between conservation research and conservation practice.

    Elevated atmospheric [CO2] (ca) will undoubtedly affect the metabolism of tropical forests worldwide; however, critical aspects of how tropical forests will respond remain largely unknown. Here we review the current state of knowledge about physiological and ecological responses, with the aim of providing a framework that can help to guide future experimental research. Modelling studies have indicated that elevated ca can potentially stimulate photosynthesis more in the tropics than at higher latitudes, because suppression of photorespiration by elevated ca increases with temperature. However, canopy leaves in tropical forests could also potentially reach a high temperature threshold under elevated ca that will moderate the rise in photosynthesis. Belowground responses, including fine root production, nutrient foraging, and soil organic matter processing, will be especially important to the integrated ecosystem response to elevated CO2. Water-use efficiency will increase as ca rises, potentially impacting upon soil moisture status and nutrient availability. Recruitment may be differentially altered for some functional groups, potentially decreasing ecosystem carbon storage. Whole-forest CO2 enrichment experiments are urgently needed to test predictions of tropical forest functioning under elevated ca. Smaller scale experiments in the understory and in gaps would also be informative, and could provide stepping stones toward stand-scale manipulations.

    2014-03-01

    This article is a review of the foundation (in 1838) and later developments of the Helsinki (Finland) magnetic and meteorological observatory, today the Finnish Meteorological Institute (FMI). The main focus of the study is in the early history of the FMI up to the beginning of the 20th century. The first director of the observatory was Physics Professor Johan Jakob Nervander (1805-1848). He was a famous person of the Finnish scientific, academic and cultural community in the early decades of the 19th century. Finland was an autonomously part of the Russian Empire from 1809 to 1917, but the observatory remained organizationally under the University of Helsinki, independent of Russian scientific institutions, and funded by the Finnish Government. Throughout the late-19th century the Meteorological Institute was responsible of nationwide meteorological, hydrological and marine observations and research. The observatory was transferred to the Finnish Society of Sciences and Letters under the name the Central Meteorological Institute in 1881. The focus of the work carried out in the Institute was changed gradually towards meteorology. Magnetic measurements were still continued but in a lower level of importance. The culmination of Finnish geophysical achievements in the 19th century was the participation to the International Polar Year programme in 1882-1883 by setting up a full-scale meteorological and magnetic observatory in Sodankylä, Lapland.

    Forest canopy has crucial roles in regulating energy and material exchange between the atmosphere and terrestrial ecosystems and in ecological processes with respect to carbon cycle and growth in the ecosystems. Challenges to the canopy of tall forests for such research involve the access to the leaves for ecophysiological observations, responses of leaves to the changing environments from seconds to years, and up-scaling the leaf-level phenomena to canopy and landscape-levels. A long-term, multidisciplinary approach has been conducted in a cool-temperate deciduous broadleaf forest in Takayama site (ca. 1400m a.s.l.) in central Japan. This forest canopy is dominated by Quercus crispula and Betula ermanii. We have been focusing on the phenology of photosynthetic productivity from a single leaf to canopy, and to landscape level, by combining leaf ecophysiological research, optical observations by spectroradiometers and time-laps cameras with the aid of "Phenological Eyes Network (PEN)", and process-based modellings. The canopy-level photosynthesis is then compared with the micrometeorolgical observation of CO2 flux at the site. So far we have been clarifying that (1) inter-annual variations in seasonal growth rate and senescence rate of leaf photosynthetic capacity and canopy leaf area are largely responsible for the inter-annual change in forest photosynthesis, and (2) spectral vegetation indices such as enhanced vegetation index (EVI) and chlorophyll index (CCI) can be the indicator to observe the phenology of forest canopy photosynthesis. In addition to these efforts since 2003, we established an open-field warming experiment on the branches of the canopy trees, to investigate the possible influence of temperature increase on leaf photosynthetic and optical properties and then to examine whether the optical satellite remote sensing can detect the changes in photosynthetic capacity and phenology by ongoing global warming.

    The report questions the forest land subject to intensive outbreaks of gypsy moth (Lymantria dispar L.) which become less susceptible to defoliation. A model for estimating the lifelihood of gypsy moth defoliation has been developed and validated. It was applied to forest-inventory plot data to quantity trends in the susceptibility of forest land in south-central Pennsylvania during a period of intensive infestation. Results show that even though susceptibility of the region's forest apparently has declined, the potential for future infestations remains relatively high.

  19. Renewal of Collaborative Research: Economically Viable Forest Harvesting Practices That Increase Carbon Sequestration

    Forests provide wildlife habitat, water and air purification, climate moderation, and timber and nontimber products. Concern about climate change has put forests in the limelight as sinks of atmospheric carbon. The C stored in the global vegetation, mostly in forests, is nearly equivalent to the amount present in atmospheric CO{sub 2}. Both voluntary and government-mandated carbon trading markets are being developed and debated, some of which include C sequestration resulting from forest management as a possible tradeable commodity. However, uncertainties regarding sources of variation in sequestration rates, validation, and leakage remain significant challenges for devising strategies to include forest management in C markets. Hence, the need for scientifically-based information on C sequestration by forest management has never been greater. The consequences of forest management on the US carbon budget are large, because about two-thirds of the {approx}300 million hectare US forest resource is classified as 'commercial forest.' In most C accounting budgets, forest harvesting is usually considered to cause a net release of C from the terrestrial biosphere to the atmosphere. However, forest management practices could be designed to meet the multiple goals of providing wood and paper products, creating economic returns from natural resources, while sequestering C from the atmosphere. The shelterwood harvest strategy, which removes about 30% of the basal area of the overstory trees in each of three successive harvests spread out over thirty years as part of a stand rotation of 60-100 years, may improve net C sequestration compared to clear-cutting because: (1) the average C stored on the land surface over a rotation increases, (2) harvesting only overstory trees means that a larger fraction of the harvested logs can be used for long-lived sawtimber products, compared to more pulp resulting from clearcutting, (3) the shelterwood cut encourages growth of subcanopy trees by opening up the forest canopy to increasing light penetration. Decomposition of onsite harvest slash and of wastes created during timber processing releases CO{sub 2} to the atmosphere, thus offsetting some of the C sequestered in vegetation. Decomposition of soil C and dead roots may also be temporarily stimulated by increased light penetration and warming of the forest floor. Quantification of these processes and their net effect is needed. We began studying C sequestration in a planned shelterwood harvest at the Howland Forest in central Maine in 2000. The harvest took place in 2002 by the International Paper Corporation, who assisted us to track the fates of harvest products (Scott et al., 2004, Environmental Management 33: S9-S22). Here we present the results of intensive on-site studies of the decay of harvest slash, soil respiration, growth of the remaining trees, and net ecosystem exchange (NEE) of CO{sub 2} during the first six years following the harvest. These results are combined with calculations of C in persisting off-site harvest products to estimate the net C consequences to date of this commercial shelterwood harvest operation. Tower-based eddy covariance is an ideal method for this study, as it integrates all C fluxes in and out of the forest over a large 'footprint' area and can reveal how the net C flux, as well as gross primary productivity and respiration, change following harvest. Because the size of this experiment precludes large-scale replication, we are use a paired-airshed approach, similar to classic large-scale paired watershed experiments. Measurements of biomass and C fluxes in control and treatment stands were compared during a pre-treatment calibration period, and then divergence from pre-treatment relationships between the two sites measured after the harvest treatment. Forests store carbon (C) as they accumulate biomass. Many forests are also commercial sources of timber and wood fiber. In most C accounting budgets, forest harvesting is usually considered to cause a net release of C from the terrestrial biosphere to the atmosphere. However, it might also be possible for commercial use of forests to contribute to terrestrial sequestration of C. The objective of the our research project is to determine whether shelterwood cutting regimes now being adopted in the commercial forests of Maine and other areas of the country can achieve these multiple goals.

  20. Finnish psychiatry--past and present.

    PubMed

    Pylkknen, Kari

    2012-03-01

    The history of Finnish psychiatry has been characterized by polarizations: priority in hospitals vs. outpatient care, centralized vs. decentralized organization, independent vs. integrated administration, biological vs. psychological treatments, private vs. public production, special psychiatric policies vs. general health policies. The independent psychiatric organizations on District level lasted from the 1920s until 1990. Since then, the formerly independent psychiatry was subordinated to General Hospital administration and the centralized system of state planning and financing of healthcare was gradually decentralized and run down. During the heavy Finnish economic recession of the early 1990 s, the cuts of the public sector were unfortunately focused most heavily on psychiatric services. The main focus of research and teaching has shifted from earlier emphasis on psychoanalytical approach to biological psychiatry since the late 1980s. The administrative position of psychiatry has been repeatedly changing and unstable during the last 20 years. At the level of the contents of the services, however, there have been many very positive and promising developments. Psychiatry has come closer to other specialties from its formerly isolated position, when the separate administrations have been integrated. Provision of outpatient services has increased remarkably, while the number of hospital beds has decreased radically. Interest and resources in research have increased remarkably, and numerous new and good quality psychiatric research reports are being published. PMID:21770822

    Tropospheric ozone (O(3)) was first determined to be phytotoxic to grapes in southern California in the 1950s. Investigations followed that showed O(3) to be the cause of foliar symptoms on tobacco and eastern white pine. In the 1960s, "X" disease of ponderosa pines within the San Bernardino Mountains was likewise determined to be due to O(3). Nearly 50 years of research have followed. Foliar O(3) symptoms have been verified under controlled chamber conditions. Studies have demonstrated negative growth effects on forest tree seedlings due to season-long O(3) exposures, but due to complex interactions within forest stands, evidence of similar losses within mature tree canopies remains elusive. Investigations on tree growth, O(3) flux, and stand productivity are being conducted along natural O(3) gradients and in open-air exposure systems to better understand O(3) effects on forest ecosystems. Given projected trends in demographics, economic output and climate, O(3) impacts on US forests will continue and are likely to increase. PMID:17084004

    Purpose - The purpose of this study is to evaluate how LEAN thinking is used as a management and development tool in the Finnish public healthcare system and what kind of outcomes have been achieved or expected by using it. The main focus is in managing and developing patient and treatment processes. Design/methodology/approach - A mixed-method approach incorporating the Webropol survey was used. Findings - LEAN is quite a new concept in Finnish public healthcare. It is mainly used as a development tool to seek financial savings and to improve the efficiency of patient processes, but has not yet been deeply implemented. However, the experiences from LEAN initiatives have been positive, and the methodology is already quite well-known. It can be concluded that, because of positive experiences from LEAN, the environment in Finnish healthcare is ready for the deeper implementation of LEAN. Originality/value - This paper evaluates the usage of LEAN thinking for the first time in the public healthcare system of Finland as a development tool and a management system. It highlights the implementation and achieved results of LEAN thinking when used in the healthcare environment. It also highlights the expectations for LEAN thinking in Finnish public healthcare.

    Change of climate conditions influence energy fluxes applicable to forest ecosystems. These affect cycles of nutrients and materials, primary productivity of the ecosystem, biodiversity, ecological functionality and, consequently, carbon equilibria of the forest ecosystem. Temporal factors influence physical, biological, ecological, and climatic processes and functions. For example, seasonality, cycles, periodicity, and trends in climate variables; tree growth, forest growth, and forest metabolic activities (i.e., photosynthesis and respiration) are commonly known to be time-related. In tropical forests, the impacts of changing climate conditions may exceed temperature and/or precipitation thresholds critical to forest tree growth or health. Historically, forest management emphasises growth rates and financial returns as affected by species and site. Until recently, the influence of climate variability on growth dynamics has not been influential in forest planning and management. Under this system, especially in climatic and forest regions where most of species are stenoecious, periodical wood harvesting may occur in any phase of growth (increasing, decreasing, peak, and trough). This scenario presents four main situations: a) harvesting occurs when the rate of growth is decreasing: future productivity is damaged; the minimum biomass capital may be altered, and CO2 storage is negatively affected; b) harvesting occurs during a trough of the rate of growth: the minimum biomass capital necessary to preserve the resilience of the forest is damaged; the damage can be temporary (decades) or permanent; CO2 storage capacity is deficient - which may be read as an indirect emission of CO2 since the balance appears negative; c) harvesting occurs when the rate of growth is increasing: the planned wood mass can be used without compromising the resilience and recovery of the forest; CO2 storage remains increasing; d) harvesting occurs during a peak period of growth: the wood mass harvested can be even higher than planned, and the rate of CO2 storage can be above the average. A real risk for SFM under changing climatic conditions is that negative effects may be amplified; critical thresholds of temperature and/or rainfall for tree growth and stress may be exceeded with impacts on growth response, resilience, and CO2 balance that are not completely known. Furthermore, temporal changes in silvicultural and harvesting operations may lead to increased carbon emissions. Under this scenario and the consequent risks to SFM forestry operations should be planned or scheduled in periods when climate variables influencing tree growth and stress are within the relative thresholds. In this way, silvicultural operations and harvesting are going to be optimised to climate variability and forest growth responses, rather than just forest timber production.

  11. Chimpanzee responses to researchers in a disturbed forest-farm mosaic at Bulindi, western Uganda.

    2010-09-01

    We describe the behavior of a previously unstudied community of wild chimpanzees during opportunistic encounters with researchers in an unprotected forest-farm mosaic at Bulindi, Uganda. Data were collected during 115 encounters between May 2006 and January 2008. Individual responses were recorded during the first minute of visual contact. The most common responses were "ignore" for arboreal chimpanzees and "monitor" for terrestrial individuals. Chimpanzees rarely responded with "flight". Adult males were seen disproportionately often relative to adult females, and accounted for 90% of individual responses recorded for terrestrial animals. Entire encounters were also categorized based on the predominant response of the chimpanzee party to researcher proximity. The most frequent encounter type was "ignore" (36%), followed by "monitor" (21%), "intimidation" (18%) and "stealthy retreat" (18%). "Intimidation" encounters occurred when chimpanzees were contacted in dense forest where visibility was low, provoking intense alarm and agitation. Adult males occasionally acted together to repel researchers through aggressive mobbing and pursuit. Chimpanzee behavior during encounters reflects the familiar yet frequently agonistic relationship between apes and local people at Bulindi. The chimpanzees are not hunted but experience high levels of harassment from villagers. Human-directed aggression by chimpanzees may represent a strategy to accommodate regular disruptions to foraging effort arising from competitive encounters with people both in and outside forest. Average encounter duration and proportion of encounters categorized as "ignore" increased over time, whereas "intimidation" encounters decreased, indicating some habituation occurred during the study. Ecotourism aimed at promoting tolerance of wildlife through local revenue generation is one possible strategy for conserving great apes on public or private land. However, the data imply that habituating chimpanzees for viewing-based ecotourism in heavily human-dominated landscapes, such as Bulindi, is ill-advised since a loss of fear of humans could lead to increased negative interactions with local people.

  18. Diel patterns of soil respiration in a moist subtropical forest: key drivers and future research needs

    Gutiérrez del Arroyo, O.; Wood, T. E.

    2014-12-01

    Moist tropical forests have the highest soil respiration rates (Rs) of any terrestrial ecosystem and account for approximately one third of the world's soil carbon (C) pool. Small increases in the magnitude of Rs in these ecosystems can result in high rates of soil C loss, with significant consequences for global climate change. Identifying the climatic controls of Rs in moist subtropical forests will improve our ability to predict how this large C flux will respond to climate change. Our objectives were (1) to determine whether Rs varies on diel timescales, (2) whether diel Rs patterns vary seasonally, and (3) identify biophysical drivers of this temporal variation. We measured hourly Rs in a secondary, moist subtropical forest in Puerto Rico for a 3-year period using an automated soil respiration system (LI-COR 8100/8150 with six chambers). Concomitant with Rs we measured hourly variation in several climatic drivers (air/soil temperature, soil moisture, relative humidity, and photosynthetically active radiation). Soil respiration showed significant diel variation, with the magnitude, amplitude, and shape of these curves varying throughout the year. Overall, diel Rs peaked in the late afternoon and reached a minimum in the early morning. Diel amplitudes ranged from 1 to 7 μmol CO2 m-2 s-1, with larger amplitudes occurring in warmer months that also have higher rates of Rs. In warmer months Rs exhibited a strong bimodal pattern, and a narrower diel range with a single peak in cooler and drier months. Diel Rs was positively correlated with soil temperature, but this relationship was non-linear during the day and linear at night (i.e., hysteresis). The bimodal pattern of Rs may be due to a mid-day depression of photosynthesis when humidity is low and air temperature is high, thereby reducing transport of photosynthate to the roots and decreasing rhizospheric respiration. The hysteresis between Rs and temperature suggests multiple controls on Rs on diel time-scales. Research that partitions Rs into its components could provide insight into their respective sensitivities to different climatic drivers, improving our capacity to understand the effects of climate change on the tropical forest C cycle.

    Along term ecological research was carried out in a Hungarian oak forest, in "Bükk" National Park starting with 1972. During the faunistical studies 3,602 insect species and more than 200,000 individuals were collected. The dominant orders were Coleoptera (1,051 species), Lepidoptera (803 species), Hymenoptera (470 species) and Diptera (400 species). The relative species abundance (RSA) for all insects collected in all years of sampling period suggests a rather J shape curve than a not clear scaling property. This means that we were able to identify almost three quarters of the insect species from one ha European oak forest during the survey (from 1987 to 2003), and two third of the staphylinides expected. Considering the staphylinid fauna a total number of 160 species and 4,022 individuals were collected. The most widely occurring species in dominance order were: Ocypus biharicus, Pseudocypus mus, Atheta gagatina, Philonthus quisquiliarius, Oxypoda acuminate, Platydracus chalcocephalus, Atheta crassicomis, Latrimaeum atrocephalum, Haploglossa puncticollis, Philonthus succicola and Anotylus mutator. The pooled value of alpha diversity was 1.51. The Shannon-Weiner Index (H') was relatively high (3.29) in comparison with other studies. PMID:18831387

    Investigations with large-scale forest lysimeter research of the lowlands of Northeast Germany - Results and consequences for the choice of tree species and forest management Introduction At present about 28 % - i.e. 1.9 million hectares - of the Northeast German Lowlands are covered with forests. The Lowlands are among the driest and at the same time the most densely wooded regions in Germany. The low annual precipitation between 500 and 600 mm and the light sandy soils with their low water storage capacity and a high porosity lead to a limited water availability. Therefore the hydrological functions of forests play an important role in the fields of regional water budget, water supply and water distribution. Experimental sites Lysimeters are suitable measuring instruments in the fields of granular soils and loose rocks to investgate evaporation and seepage water. The usage of lysimeter of different construction has a tradition of more than 100 years in this region. To investigate the water consumption of different tree species, lysimeters were installed at Britz near Eberswalde under comparable site conditions. In the early 1970s nine large-scale lysimeters were built with an area of 100 m2 and a depth of 5 m each. In 1974 the lysimeters were planted, together with their environment, with Scots pine (Pinus sylvestris L), common beech (Fagus sylvatica L.), larch (Larix decidua L.) and Douglas-fir (Pseudotsuga menziesii [Mirb.] FRANCO) as experimental stands of 0.5 ha each according to the usual management practices. Therefore the "Large-scale lysimeters of Britz" are unparalleled in Europe. It was the initial aim of the experiment to find out the influence of the species and age of the growing stock growing on identical sandy soil under comparable weather conditions on both natural groundwater recharge and evaporation. Future forests in the north-eastern lowlands of Germany shall be mixed stands with as large a number of different species as possible. And this is also the aim of forest conversion in Land Brandenburg. The programme requires scientific attendance and foundation. In particular it shall be examined how the hydro-ecological conditions - which often are the limiting factor for forest growth in this area - would change with underplanted pine and larch and how these conditions may benefit from stand-structural and forestry measures. This is why several lysimeter stands were changed as follows: Ø Larch underplanted with beech Ø Scots pine underplanted with beech Ø Scots pine underplanted with oak Results Forests with their special hydrological properties have a substantial influence on the water budget, water supply and water distribution of entire landscapes. The tree species is of outstanding importance for deep seepage under forest stands. The sum of transpiration gives a rough overview about the water budget of the forest stand. More important for the detection of interactions between the compartments is the partitioning of the whole evaporation into individual evaporation components. Under the given precipitation and soil conditions, the course of interception and hence, the amount of seepage water depend on the crown structure in the stand. Depending on the amount of interception of the tree canopy and the duration of the leaching phase in spring, the mixed stands range between pure pine and pure beech. Making use of silvicultural methods and adequate stand treatment, forestry is able to control the water budget of landscapes.

    The Wave Scattering Research Center at the University of Texas at Arlington has developed a scattering model for forest or vegetation, based on the theory of electromagnetic-wave scattering in random media. The model generalizes the assumptions imposed by earlier models, and compares well with measurements from several forest canopies. This paper gives a description of the model. It also indicates how the model elements are integrated to obtain the scattering characteristics of different forest canopies. The scattering characteristics may be displayed in the form of polarimetric signatures, represented by like- and cross-polarized scattering coefficients, for an elliptically-polarized wave, or in the form of signal-distribution curves. Results illustrating both types of scattering characteristics are given.

    2013-08-01

    This article reviews the recent literature concerning airborne laser scanning for forestry purposes in Italy, and presents the current methodologies used to extract forest characteristics from discrete return ALS (Airborne Laser Scanning) data. Increasing interest in ALS data is currently being shown, especially for remote sensing-based forest inventories in Italy; the driving force for this interest is the possibility of reducing costs and providing more accurate and efficient estimation of forest characteristics. This review covers a period of approximately ten years, from the first application of laser scanning for forestry purposes in 2003 to the present day, and shows that there are numerous ongoing research activities which use these technologies for the assessment of forest attributes (e.g., number of trees, mean tree height, stem volume) and ecological issues (e.g., gap identification, fuel model detection). The basic approaches - such as single tree detection and area-based modeling - have been widely examined and commented in order to explore the trend of methods in these technologies, including their applicability and performance. Finally this paper outlines and comments some of the common problems encountered in operational use of laser scanning in Italy, offering potentially useful guidelines and solutions for other countries with similar conditions, under a rather variable environmental framework comprising Alpine, temperate and Mediterranean forest ecosystems.

    This National Science Foundation (NSF) Research Experience for Undergraduates (REU) site hosted by Texas A&M University to allow selected undergraduate students to conduct original research on various aspects of the ecohydrology of understudied tropical pre-montane forest at the Texas A&M Soltis Center for Research and Education in Central Costa Rica. This particular study was conducted by 3 students under the guidance of 5 mentors who assisted in experimental design, equipment use, maintenance, and training, plant species identification and other logistical requirements. The goal of this study was to determine the change in 3-D structure of tropical premontane wet forest under 3 different land uses: a carbon tree farm, secondary logged forest, and primary unlogged forest. Traditional forest mensuration techniques including glass prisms (stand basal area), laser clinometers (height), vertical and horizontal PAR, spherical densiometers, and hemispherical photography (GAP fraction and LAI) and, root cores, and diameter-at-breast height (DBH) tapes were acquired in one 30-m diameter plot per land and use compared to similar metrics collected by a terrestrial scanning laser (TSL) and ground penetrating radar (GPR) at 400 MHz and 1.5 GHz across 3 land uses along an elevation gradient from ~380-masl to 525-masl. Besides discovery, another goal of this study was to see if the TSL and GPR can help meet the Tier 2 and 3 monitoring and verification goals of the United Nations Collaborative Programme on Reducing Emissions from Deforestation and Forest Degradation in Developing Countries for estimating above- and below-ground biomass using remote sensing. This is of particular importance because the GPR may be able to capture below-ground biomass in a more efficient manner than traditional coring and the TSL and GPR can capture data on highly sloped terrain where both airborne and satellite RADAR and LIDAR are limited. The 50, 000 pts/sec 532 nm TSL collected 3 to 5 scans per 30-m diameter plots at 4-cm spacing, 270° vertical, and 360° horizontal, generating a >100 million point cloud per site at ±2-mm range accuracy. Registration within 2-mm RMSE yielded a 3-D virtual environment per site where tree measurements were made manually. Comparisons showed that GPR may be masked by high soil moisture. DBH error measures ranged from ± 0.6 to 5.18 % and height was 0.26 to 20.19 % for carbon farm to primary forest. The height comparison indicated that the laser clinometer consistently underestimated tree heights, particularly on the primary forest site where trees were over 35-m.

    We have modified Semliki Forest virus (SFV) vectors to broaden their application range. Here we describe a series of site-directed mutagenesis experiments on the SFV subgenomic 26S promoter to down-regulate the heterologous gene expression. Several mutants showed a dramatic effect on transgene expression levels in BHK cells. The luciferase activity was reduced to approximately 30%, 3%, and 1% compared to the wild type promoter. Similarly, a decrease in beta-galactosidase activity was observed in BHK cells and after injection into the striatum of male Wistar rats. Novel non-cytopathogenic and temperature-sensitive SFV vectors have recently been developed by introduction of point mutations in the viral nonstructural genes nsP2 and nsP4. These vectors do not show the typical shut down of host cell protein synthesis after SFV infections and therefore allow for a substantially prolonged survival of host cells. Both the mutant vectors demonstrating lower and more physiological expression levels and the non-cytopathogenic vectors should be valuable tools for various applications within receptor research. Furthermore, recent studies suggest that SFV vectors can be efficient gene delivery vehicles for gene therapy applications. PMID:11693173

  12. Current status and trends in Timber Severance Tax Legislation in the south. Forest Service research note

    SciTech Connect

    Haines, T.K.

    1995-01-01

    Severance tax programs currently exist in eight States in the South. These laws have been enacted primarily to encourage better forest management and to provide revenues for a variety of forest management and to provide revenues for a variety of forestry initiatives. In most States, either the severer or the primary processor of forest products is designated as the taxpayer. Severance tax rates are established as either: (1) a fixed amount per unit of measurement or (2) a percentage of the value of timber harvested. Severance tax receipts have increased across the South since 1987, a trend that will continue if anticipated demand for southern wood products is realized.

  13. The ash in forest fire affected soils control the soil losses. Part 1. The pioneer research

    2013-04-01

    After forest fires, the ash and the remaining vegetation cover on the soil surface are the main protection against erosion agents. The control ash exert on runoff generation mechanism was researched during the 90's (Cerdà, 1998a; 1998b). This pioneer research demonstrated that after forest fires there is a short period of time that runoff and surface wash by water is controlled by the high infiltration rates achieved by the soil, which were high due to the effect of ash acting as a mulch. The research of Cerdà (1998a; 1998b) also contributed to demonstrate that runoff was enhanced four month later upon the wash of the ash by the runoff, but also due to the removal of ash due to dissolution and water infiltration. As a consequence of the ephemeral ash cover the runoff and erosion reached the peak after the removal of the ash (usually four month), and for two years the soil erosion reached the peak (Cerdà, 1998a). Research developed during the last decade shown that the ash and the litter cover together contribute to reduce the soil losses after the forest fire (Cerdà and Doerr, 2008). The fate of the ash is related to the climatic conditions of the post-fire season, as intense thunderstorms erode the ash layer and low intensity rainfall contribute to a higher infiltration rate and the recovery of the vegetation. Another, key factor found during the last two decades that determine the fate of the ash and the soil and water losses is the impact of the fauna (Cerdà and Doerr, 2010). During the last decade new techniques were developed to study the impact of ash in the soil system, such as the one to monitor the ash changes by means of high spatial resolution photography (Pérez Cabello et al., 2012), and laboratory approaches that show the impact of ash as a key factor in the soil hydrology throughout the control they exert on the soil water repellency (Bodí et al., 2012). Laboratory approaches also shown that the fire severity is a key factor on the ash chemical composition (Pereira and Úbeda, 2010) and Pereira et al., 2012). Some of the new research challenges related to ash impact in the fire affected soils are related to the ash redistribution after the fire, the impact of ash in soil and water chemistry, the temporal changes of soil erosion, the control ash exert on vegetation recovery and the role to be played by ash in the best management of fire affected land. Those topics needs new ideas and new scientists such as Paulo Pereira show in the Part II of this abstract. Acknowledgements, Lithuanian Research Council.

    An international cooperative project on distribution of ozone in the Carpathian Mountains, Central Europe was conducted from 1997 to 1999. Results of that project indicated that in large parts of the Carpathian Mountains, concentrations of ozone were elevated and potentially phytotoxic to forest vegetation. That study led to the establishment of new long-term studies on ecological changes in forests and other ecosystems caused by air pollution in the Retezat Mountains, Southern Carpathians, Romania and in the Tatra Mountains, Western Carpathians on the Polish-Slovak border. Both of these important mountain ranges have the status of national parks and are Man & the Biosphere Reserves. In the Retezat Mountains, the primary research objective was to evaluate how air pollution may affect forest health and biodiversity. The main research objective in the Tatra Mountains was to evaluate responses of natural and managed Norway spruce forests to air pollution and other stresses. Ambient concentrations of ozone (O(3)), sulfur dioxide (SO(2)), nitrogen oxides (NO(x)) as well as forest health and biodiversity changes were monitored on densely distributed research sites. Initial monitoring of pollutants indicated low levels of O(3), SO(2), and NO(x) in the Retezat Mountains, while elevated levels of O(3) and high deposition of atmospheric sulfur (S) and nitrogen (N) have characterized the Tatra Mountains. In the Retezat Mountains, air pollution seems to have little effect on forest health; however, there was concern that over a long time, even low levels of pollution may affect biodiversity of this important ecosystem. In contrast, severe decline of Norway spruce has been observed in the Tatra Mountains. Although bark beetle seems to be the immediate cause of that decline, long-term elevated levels of atmospheric N and S depositions and elevated O(3) could predispose trees to insect attacks and other stresses. European and US scientists studied pollution deposition, soil and plant chemistry, O(3)-sensitive plant species, forest insects, and genetic changes in the Retezat and Tatra Mountains. Results of these investigations are presented in a GIS format to allow for a better understanding of the changes and the recommendations for effective management in these two areas. PMID:12676229

    At the Forest Products Laboratory (FPL) of the USDA Forest Service at Madison, WI, scientists are studying microorganisms and their enzymes to find new ways of converting wood to products like pulp, chemicals, and even food. The institute is focusing on lignin biodegradation, direct conversion of solid wood, and fermentation of hemicellulose sugars from wood. Forming the Institute is really the laboratory's way of stressing the importance of basic research in this new area and emphasizing the potential for biotechnology in wood utilization. The work is highly basic in nature and focuses on long-range problems that private industry cannot afford to do and universities find difficult to do. They are, however, working closely with several major universities in each of the three research areas.

  2. Soil carbon balance on drained and afforested transitional bog in forest research station Vesetnieki in Latvia

    2015-04-01

    Around 0.8 mill. ha forests in Latvia are located on organic soils and 0.5 mill. ha of these forests are drained. Drainage of organic soils alters carbon stock and may has impact on the climate change. The aim of this study is to analyse the impact of drainage on a soil carbon stock in transitional bog (average growing stock before drainage 50 m3*ha-1) located in central part of Latvia in research station "Vesetnieki". Drainage was done in 1960. Average peat thickness is around 4.5 m; dominant tree species are pine (Pinus sylvestris L.) and spruce (Picea abies Karst.) with average growing stock 226 m3*ha-1 and 213 m3*ha-1. Volumetric peat samples were taken from soil surface down to 80 cm depth in 30 sample plots in drained sites and non-drained areas (transitional bog), which have been left as a control. Bulk density, carbon content in peat was determined to evaluate carbon stock changes in soil. Ground surface levelling in drained sites was done before drainage and repeatedly in 1966, 1970, 1975, 1977, 1982 and 2014 to calculate peat subsidence. The rate of peat subsidence after drainage increased rapidly, and 14 years after drainage 15.8 cm decrease of the surface level was found. The rate of the peat subsidence decreased later, and the ground level reduced by 9.9 cm in the following 40 years, reaching 25.7±3.5 cm from initial ground surface level in the 2014. The rapid decrease of the surface level after drainage can be explained by physical alters and by decomposition of the peat surface layers, however, it is not possible to assess now, which of these processes dominated. However, the significant (α=0.05) increase of the peat bulk density and carbon content in upper layers (0-80 cm) in drained sites compared to non-drained leads to conclusion that the compaction was the dominating process. Average carbon stock (0-80 cm deep soil layer) in non-drained areas is 339±29 tons*ha-1 and 513±27 tons*ha-1 in drained sites. We compared carbon stock in upper 80 cm soil layer in transitional bog (339±29 tons*ha-1) with peat layer in drained sites 54.3 cm corresponding to 80 cm in non-drained (359±19 tons*ha-1). The study reveals that soils in drained sites have accumulated 0.36 tons*ha-1*a-1 more carbon than soils in non-drained sites, however the difference on carbon stock between sites is not statistically significant (α=0.05). If non-drained organic soils are considered to be a carbon sink or at least not a carbon source, then we can conclude that drained organic soil in research station "Vesetnieki" in 50 years period did not become a carbon source.

    1992-11-01

    General Circulation Models (GCMs) have projected global warming of from 3 to 8 degrees F to take place over a period of from 50 to 100 years. The Forest Service Southern Global Change Program (SGCP) has proposed the use of GCM output as input to forest assessment models to estimate the potential impacts of climate changes on forests of the South and Southeastern U.S. The report reviews, organizes, summarizes and makes recommendations concerning the use of four climate model projections in forest assessments. Some primary sources of inter-model variability include model version (age), numerical solution technique, time and space resolution and parameterization schemes. Model version generally impacts the time and space resolution and choice of parameterization schemes. Magnitude of change varies widely, but the four GCMs examined here all project warmer air temperatures and higher humidities throughout the year, decreasing cloud cover during the Fall, Winter and Spring seasons and increasing summertime precipitation for the South and Southeastern U.S. Although some consensus among models over large geographic regions can be identified, there is, as yet, no established means of determining the confidence that can be placed in these outlooks. GCM output should be combined with historical case studies, empirical and semi-empirically constructed climate scenarios to provide a range of possible climatological futures.

    This technical report covers a 3-year cooperative agreement between the University of Maine and the Northeastern Forest Experiment Station that focused on the characterization of forest stands and the assessment of forest carbon storage (see attached for detailed description of the project). The goal of this work was to compare estimates of forest C storage made via remeasurement of FIA-type plots with eddy flux measurements. In addition to relating whole ecosystem estimates of carbon storage to changes in aboveground biomass, we explored methodologies by partitioning growth estimates from periodic inventory measurements into annual estimates. In the final year, we remeasured plots that were subject to a shelterwood harvest over the winter of 2001-02 to assess the production of coarse woody debris by this harvest, to remeasure trees in a long-term stand first established by NASA, to carry out other field activities at Howland, and, to assess the importance of downed and decaying wood as well as standing dead trees to the C inputs to harvested and non harvested plots.

    Biodeterioration is associated with virtually all types of wood structures, including bridges, mine timbers, utility poles, marine structures, and railroad ties. Scientists in the Biodeterioration of Wood Unit at the Forest Products Laboratory, USDA Forest Service, are exploring new approaches for detecting and preventing wood decay. The report describes progress in developing immunological procedures for detecting decay. The report also describes simple in-place preventive and remedial treatments for protecting wood from biodeterioration by mold, sapstain, and decay fungi. Timber has been estimated to increase in value nearly 24 times between the stump and delivery of the finished product. Thus, research that improves the service-life of wood has potential for high financial return.

    Since 1982, under an agreement between the California Department of Water Resources and the USDA Forest Service, snow sensors have been installed and operated in Forest Service-administered wilderness areas in the Sierra Nevada of California. Because analysis of snow water equivalent(SWE) data from these wilderness sensors would not be possible until just before they are due to be removed, surrogate pairs of high- and low-elevation snow sensors were selected to determine whether correlation and prediction might be achieved. Surrogate pairs of sensors with between 5 and 15 years of concurrent data were selected, and correlation and regression were used to examine the statistical feasibility of SWE prediction after removal of the wilderness sensors. Of the 10 pairs analyzed, two pairs achieved a correlation coefficient of 0.95 or greater.

    The importance of biogenic volatile organic compounds (BVOCs) in understanding of air-quality and climate on regional to global scales has been highlighted in a number of modeling and observational studies. At the same time, another important emerging research topic in atmospheric chemistry is the regional and global impacts of fast growing East Asian megacities. These two research topics must be integrated in order to adequately understand and address air quality challenges emerging from Eastern Asian megacities surrounded by planted or natural forest areas. We present initial measurement results for May, June and September 2011 from the Taehwa Research Forest (TRF) which has been developed to serve as a long term observatory for investigating biosphere-atmosphere interactions at the edge of the Seoul Metropolitan Area (population of ˜23.5 million). The comprehensive measurement datasets of ozone and its precursors such as CO, NOx, SO2 and VOCs shows that high ozone episodes in the suburban site could not be explained by just anthropogenic pollutants alone. In addition, isoprene (C5H8) and monoterpenes (C10H16) were observed as two of the most important OH chemical sinks inside of the forest canopy. In order to understand the impacts of these BVOCs on ozone and related photochemistry, we conducted model sensitivity simulations using a coupled meteorology-chemistry model (WRF-Chem) for conditions including with and without BVOC emissions. The modeling results suggest that BVOC emissions could enhance regional daytime ozone production from 5 to 20 ppbv. The observed temporal variations in ozone correspond well with the variations in BVOCs, which likely reflects the influence of BVOCs on ozone formation. These findings strongly suggest that interactions between anthropogenic pollutants and BVOCs must be understood and quantified in order to assess photochemical ozone formation in the regions surrounding East Asian megacities.

    The report includes the framework represented as a matrix of potential threats and attributes of wilderness character. Cells in the matrix represent the impacts of threats on each attribute. Potential application of the matrix are described. An application of the matrix to the wildernesses in the Forest Service's Northern Region (northern Idaho and Montana) suggests that fire management is the most significant threat to those wildernesses and that aquatic systems are the most threatened wilderness attribute.

  10. Leguminous ground covers could reduce herbicide use in forestry. Forest Service research paper

    SciTech Connect

    Ponder, F.

    1994-01-01

    Establishing tree seedlings in mixed stands after harvesting is difficult without adequate vegetation control. Artificial regeneration can be used to ensure desirable future stands, but competing vegetation decreases survival and growth. Vegetation control can be costly and laborious. Large amounts of herbicides are used annually in forest management to reduce vegetation that competes with trees for growing space, nutrients, water, light, and other essential components. Using herbicides to control weeds is economical, but may not always be environmentally acceptable. One alternative is to establish nitrogen-fixing (legume) ground covers, which may suppress the more competitive weeds and enrich the soil.

    1995-12-01

    This paper suggests solution for a longstanding problem in managing lodgepole pine forests- that of managing individual stands to reach their planned rotation age, despite serious hazard from bark beetles and wildfire. The management regimes presented yield merchantable thinning products. The 80-year sawtimber rotation can be achieved using these management recommendation. Thinning at 30 years of age is central to achieving the recommended alternative management regimes. The authors suggest that agencies give roundwood operators a portion of the thinning stemwood as payment. Management regimes that provide attainable rotations are presented in summary tables, by three site index classes and a number of initial stand density classes.

    This research investigates horse trail impacts to gain an improved understanding of the relationship between various levels of horse use, horse trail management alternatives, and subsequent horse trail degradation. A survey of existing horse trails on the Hoosier National Forest was used to collect data on use-related, environmental and management factors to model horse trail impacts. Results are analyzed to identify which factors are most easily manipulated by managers to effectively avoid and minimize horse trail impacts. A specific focus includes evaluating the relative effect of trail use level, surfacing, grade, and water control on indices of erosion and trafficability such as trail cross sectional area, estimated erosion, muddiness, and incision. Overall, the Hoosier National Forest horse trails could be significantly improved by relocating or closing inherited trails that directly ascend slope or are excessively steep, reducing the distance between water control structures, and by applying gravel to harden trail surfaces and reduce soil erosion. A set of Best Management Practices for trails are included as a product of this work, with recommendations based on this research.

    In this article, the authors discuss and evaluate the TieVie capacity building project for Finnish universities in a larger historical context of strategic developments in the use of information and communications technology (ICT) in learning. The TieVie project was a support service project for the Finnish Virtual University (FVU) which offered training in the educational use of ICT to the staff of Finnish universities in 2001-2008. It was financed by the Ministry of Education as part of the Virtual University project funding till the end of 2006. During 2007-2008, the program was fee-funded. The project was designed and implemented by the educational development support service units of five universities: Universities of Oulu, Turku, Jyväskylä, and Helsinki, and Helsinki University of Technology. The TieVie project was launched on the basis of the need to strengthen the e-Learning skills and expertise among Finnish university staff. This need was recognized in the national strategy for education, training, and research in the information society outlined by the Ministry of Education in 2000.

    The goal of this project is to recommend a broadly-acceptale efficient and effective methodology for characterizing streamside riparian attributes in forested settings at the site grain for regional monitoring. The authors consider monitoring design in the context of three interacting constraints: ecological functions, capabilities of technologies, and user needs. The focus is on fine grained remote methods. Comparison between candidate selected monitoring systems provides for an initial formulation of a monitoring design. A series of evaluations of these initial formulations provides for an initial recommendation. With the state`s interest in the status of coastal fishes, and the programmatic interest of EPA`s Western Ecology Division, the areas selected for study are in the Oregon coastal province and the Willamette basin.

  17. Salvage logging effect on soil properties in a fire-affected Mediterranean forest: a two years monitoring research

    In the Mediterranean countries, forest fires are common and must be considered as an ecological factor, but changes in land use, especially in the last five decades have provoked a modification in their natural regime. Moreover, post-fire management can have an additional impact on the ecosystem; in some cases, even more severe than the fire. Salvage logging is a traditional management in most fire-affected areas. In some cases, the way of doing it, using heavy machinery, and the vulnerability of soils to erosion and degradation make this management potentially very agresive to soil, and therefore to the ecosystem. Very little research has been done to study how this treatment could affect soil health. In this research we show 2 years of monitoring of some soil properties in an area affected by a forest fire, where some months later this treatment was applied. The study area is located in 'Sierra de Mariola Natural Park' in Alcoi, Alicante (E Spain). A big forest fire (>500 has) occurred in July 2012. The forest is composed mainly of Pinus halepensis trees with an understory of typical Mediterranean shrubs species such as Quercus coccifera, Rosmarinus officinalis, Thymus vulgaris, Brachypodium retusum, etc. Soil is classified as a Typic Xerorthent (Soil Survey Staff, 2014) developed over marls. In February 2013, salvage logging (SL) treatment consisting in a complete extraction of the burned wood using heavy machinery was applied in a part of the affected forest. Plots for monitoring this effect were installed in this area and in a similar nearby area where no treatment was done, and then used as control (C) for comparison. Soil samplings were done immediately after treatment and every 6 months. Some soil properties were analysed, including soil organic matter (SOM) content, basal soil respiration (BSR), microbial biomass carbon (MBC), bulk density (BD), soil water repellency (SWR), aggregate stability (AS), field capacity, nitrogen, etc. After two years of research, results showed significant soil degradation as a consequence of the salvage logging treatment. Most of the soil parameters studied showed differences between control and salvage logging treatments, SOM content in first 2.5 cm of topsoil being less than half in SL plots in comparison with C plots. BSR, MBC and AS were also statistically significant lower in SL plots. BD increased as a consequence of SL treatment. In conclusion, we can affirm that with this type of soil, which is very vulnerable to soil degradation, this treatment has a very negative effect on the ecosystem; this was also reflected in the abundance and diversity of plant species.

    The importance of forests as carbon sources or sinks depends, in part, upon stand age, which in turn is generally dependent on time since last disturbance. Uncertainties in North American carbon fluxes originate from poor understanding of forest dynamics, specifically disturbance and regeneration. The North American Forest Dynamics (NAFD) study, which supports North American Carbon Program (NACP) science goals, is improving understanding of North American forest dynamics through integration of U.S. Department of Agriculture (USDA) Forest Service (USFS) Forest Inventory and Analysis (FIA) field observations and biennial Landsat imagery to evaluate disturbance and regrowth patterns over the last ~ 35 years. NAFD Phase I (2005-2008) detailed forest disturbance history from Landsat time series stacks (LTSS) for 23 sample locations across the United States. Results of Phase I NAFD disturbance mapping reveal generally high rates of forest disturbance (0.5 - 3.0% per year across the U.S). These rates vary both spatially and temporally. Ongoing Phase II (2008-2011) work is refining the Phase I approach. Additional sample locations in the conterminous U.S are being added to reduce error in nationwide disturbance estimates. Detection of partial disturbances is being improved by moving toward annual rather then biennial LTSS. This is being accomplished with cloud clearing through image merging to provide within-growing season clear surface views. Additional elements of the NAFD Phase II work include partnering with Canada and Mexico to better understand North American continent-wide forest dynamics. We are also extending our effort to consider regrowth dynamics using the FIA data to support both radiative transfer modeling and synthesis of FIA and the remote sensing data to estimate biomass accumulation trends. We are also collaborating with other NACP- investigators where the NAFD products inform their alternate approaches (modeling and/ or accounting) for carbon assessment. Soon we are planning on implementing model-based estimators for the purpose of developing nationwide maps of disturbance rates, a product currently widely sought by carbon modelers.

    SciTech Connect

    Hajny, G.J.

    1981-03-01

    In the long term, mankind will have to depend on solar energy and photosynthetic processes rather than on fossil materials for energy and material needs. Cellulose and the hemicelluloses, which make up about 70 percent of the dry matter of trees and shrubs, are the most abundant, renewable, raw materials on earth. At present, the highest uses of wood are for structural material and as a source of fiber. There are, however, large quantities of wood residues produced during harvesting and manufacture that might be used. Intensive silviculture can greatly increase the supply of wood for all purposes. This paper reviews the work the U.S. Forest Products Laboratory has done over nearly 70 years to produce chemicals and feedstuffs from wood residues. Wood has been converted successfully to fermentation chemicals such as ethyl alcohol, glycerol, arabitol, erythritol, butanol, acetone, and 2,3-butylene glycol as well as to feedstuffs such as molasses and yeast, and to wood modified to make the polysaccharides digestible by ruminants. At present such use of wood is economically marginal, but is potentially economic in the future.

    Gonzalez-Hernandez, M. P.; Karchesy, J.; Starkey, E.E.

    2003-01-01

    Tannins are secondary metabolites that may influence feeding by mammals on plants. We analyzed hydrolyzable and condensed tannins in 30 plant species consumed by livestock and deer, as a preliminary attempt to study their possible implications on browsing and grazing in forest ecosystems. Heathers (Ericaceae) and plants of the Rose (Rosaceae) family had tannins, while forbs, grasses and shrubs other than the heathers did not show astringency properties. We found the highest tannin content of all the species in Rubus sp., with the highest value around 180 mg TAE/g dry weight in spring. Potentilla erecta, Alnus glutinosa and Quercus robur were next with 57 to 44 mg TAE/g dw. Total tannins in heathers ranged from 22 to 36 mg TAE/g dw. Levels of condensed tannins were higher than hydrolyzable for most of the species. Only Betula alba, Calluna vulgaris, Pteridium aquilinum and Vaccinium myrtillus had 100% hydrolyzable tannins. Tannin content of the species changed seasonally with highest values during the growing season, corresponding to late winter or early spring, depending on the species.

    2013-01-01

    Language-and culture-specific norms are needed for research on emotion-laden stimuli. We present valence and arousal ratings for 420 Finnish nouns for a sample of 996 Finnish speakers. Ratings are provided both for the whole sample and for subgroups divided by age and gender in light of previous research suggesting age- and gender-specific reactivity to the emotional content in stimuli. Moreover, corpus-based frequency values and word length are provided as objective psycholinguistic measures of the nouns. The relationship between valence and arousal mainly showed the curvilinear relationship reported in previous studies. Age and gender effects on valence and arousal ratings were statistically significant but weak. The inherent affective properties of the words in terms of mean valence and arousal ratings explained more of the variance in the ratings. In all, the findings suggest that language- and culture-related factors influence the way affective properties of words are rated to a greater degree than demographic factors. This database will provide researchers with normative data for Finnish emotion-laden and emotionally neutral words. The normative database is available in Database S1. PMID:24023650

  3. Silvicultural management in maintaining biodiversity and resistance of forests in Europe-boreal zone: case Finland.

    PubMed

    Mielikäinen, Kari; Hynynen, Jari

    2003-01-01

    The majority of untouched natural boreal forests have been regenerated through large catastrophes, occurring by intervals between 50 and 100 years. Storm and fire will open the landscape, result in a huge amount of dead or dying trees and let the pioneer tree species germinate. These processes are the guideline for Finnish forest management today. The main focus by maintaining the biodiversity in Finnish boreal forest zone is directed to managed forests. Nature-orientated silviculture on stand level is practised. The site type classification, a reflection of the modern concept of biodiversity and developed by Cajander early in 1900s, on the basis of natural vegetation composition of the site, has the central role by choosing tree species, regeneration methods and thinning procedure, and reflects also on the site productivity. The small size of stands, the abundance of natural seedlings in planted stands and the popularity of mixed stands have a positive impact on biodiversity of forests. The protection of small-sized valuable habitats in commercially managed stands, the leaving of retention trees standing and lying in the forest in all phases of the rotation, are activities made for biodiversity. Many insects and fungi are adapted to catastrophes and so they can survive in single stems left on regeneration areas. Maintaining the biodiversity in multifunctional forests is also supported by the new forest legislation and by the criteria of Finnish Forest Certification System. PMID:12659803

  5. [The "top ten" of Finnish medicine].

    In the early 1980s the Wellcome Institute was planning a biographical dictionary on the world's most eminent physicians. The quota reserved for Finland was ten names, and having been asked by Dr. Karin Johannisson, Uppsala, to participate in the project, I undertook the task of choosing them and providing a short biography of each. For this, I asked the advice of ten experts on the history of Finnish medicine, and a "top ten" list was then compiled. The list extended from Johan Haartman, "the father of Finnish medicine", till the Nobel Prize winner Ragnar Granit and the famous pediatrist Arvo Ylppo, who were still alive in the 1980s. The biographies were sent to the editor of the dictionary, but it seems that the work was never published. As I had saved all my correspondence about the matter, it seemed now, fifteen years afterwards, interesting to publish a short report of the project, including an account of how the "top ten" list had been achieved.

    Seed source and sowing date effects on first-year seedling growth and Fusarium root and collar rot of sugar pine were analyzed in two consecutive nursery tests at the Pacific Southwest Research Station's Institute of Forest Genetics, near Placerville in the western Sierra Nevada. The experimental design in both tests consisted of four replications of a randomized complete block of split-split plots, with sowing date split for disease treatment and seed source. Seed sources were natural stands at low, middle, and high elevations on the western slope of the northern Sierra Nevada. Seeds were soaked 36 hours in aerated water at 25 deg (77 deg F), chilled 90 days at 1 deg C (34 deg F), and sown in fumigated soil in February, March, April, and May. Treatment plots were drenched with fungicides just before sowing in the first test, and were inoculated with Fusarium oxysporum at time of sowing in the second test. Seedling emergence averaged 96 to 99 percent, regardless of sowing date.

    Soil organic matter not only affects soil properties and productivity but also has an essential role in global carbon (C) cycle. We studied changes in the topsoil C content of Finnish croplands using a dataset produced in nationwide soil monitoring. The monitoring network consisting of fields on both mineral and organic soils was established in 1974 and resampled in 1987, 1998, and 2009. Over the monitoring period from 1974 to 2009, cultivated soils showed a continuous decline in C concentration (g kg(-1) ). In organic soils, C concentration decreased at a mean rate of 0.2-0.3% yr(-1) relative to the existing C concentration. In mineral soils, the relative decrease was 0.4% yr(-1) corresponding to a C stock (kg m(-2) ) loss of 220 kg ha(-1)  yr(-1) . The change in management practices in last decades toward increasing cultivation of annual crops has contributed to soil C losses noted in this study. The results, however, suggest that the C losses result partly from other processes affecting cultivated soils such as climatic change or the continuing long-term effect of forest clearance. We estimated that Finnish cropland soils store 161 Tg carbon nationwide in the topmost 15 cm of which 117 Tg is in mineral soils. C losses from mineral soils can therefore total up to 0.5 Tg yearly.

    Because of their well-documented exposures to repeated low doses of ionizing radiation, nuclear reactor workers offer an opportunity to assess cancer risk from low-dose radiation. A cohort of all 15,619 Finnish nuclear reactor workers was established through dose-monitoring records. A questionnaire survey revealed no substantial differences in consumption of tobacco or alcohol between different exposure groups nor between nuclear power company employees and contract workers. In the follow-up for cancer incidence, no clear excess in cancer incidence was observed overall, nor was any observed in any of the specific cancer types studied. There was little evidence for an association between cancer incidence and cumulative radiation dose, but the statistical power was limited. More precise estimates will be available from an international collaborative study of nuclear industry workers, including our cohort. PMID:12134527

    Histories of serious suicide attempts and slashing were investigated among Finnish fire setters. Medical and criminal records of 304 fire setters were examined to compare those who had attempted suicide with those who had not, and those who had slashed themselves with those who had not using biological, diagnostic, and demographic variables. Major mood disorders, father's alcoholism, and suicidal motive of fire setting (self-immolation) were significantly associated with suicide attempts. Paternal violent alcoholism, father's criminality, and suicidal motive of fire setting were significantly associated with slashing. Among fire setters, non-lethal slashing is a predictor of serious suicidality. Associations between psychiatric diagnoses, family history, and suicidality among fire setters are similar to those reported for suicidal patients with mood and substance abuse diagnoses. Therefore, studying fire setters, who exhibit an extremely high incidence of suicidal behavior, is an effective way to elucidate psychobiology of suicidal behaviors. PMID:9477009

    This report reviews the potential role of ozone in forest decline in the United States. Recent studies suggest that forest decline, not clearly identifiable from natural causes, is occurring in eastern North America and central Europe. Ozone, because of its known effects on white pine and certain crop species, is being investigated as one factor possibly contributing to the perceived forest decline. Results to date indicate various factors may contribute to forest decline and that the specific combinations differ from site to site. The visible effects of ozone on trees produced in some laboratory experiments have, to date, not been confirmed in field experiments. Only the Ponderosa pine forests in the San Bernardino mountains of Southern California have exhibited confirmed visual damage from ambient ozone exposures. New hypotheses, based on field case studies in the eastern United States, suggest that ozone may be contributing to productivity declines in forests without visible damage symptoms. The role of ozone in forest decline is the subject of rapidly expanding research efforts, at EPRI and in federal, state and forest industry research organizations. This report provides a critical review of the published, peer-reviewed literature on the relation between ozone and forest health. It also summarizes the current state of knowledge on ozone's effects on plants and outlines areas of research under investigation.

    The ecohydrological functioning of cloud forests is intricately linked to unique plant ecophysiological traits and processes that influence water fluxes at the plot to ecosystem scales. However, despite substantial gains in our understanding of cloud forest plant ecophysiology over the past decade, integration of water flux information from the leaf to the watershed scale is still lacking. We present a synthesis of research aimed at revealing the linkages between plant ecophysiology and forest ecohydrological functioning, conducted in a seasonal cloud forest in Veracruz, Mexico. A variety of species-specific leaf-level water flux behaviors were found to influence various aspects of plant water relations, which in turn, scaled up to impact stand water balance. For example, foliar fog absorption compensated for approximately 9.3 ± 1.2% of transpiration, and nocturnal transpiration for dominant tree species during the dry-season accounted for 22% to 30% of daytime transpiration. Further, the presence of dense fog, light fog, and cloud cover was shown to reduce transpiration such that annual transpiration may increase up to 17% in the case that all fog occurrence is replaced by clear sky conditions. We discuss how these processes affect whole-plant and stand water balances, as well as the potential feedbacks of vegetation controls on hydrologic fluxes under future climate change. After placing our findings within a global context we present a conceptual model of the links between plant ecophysiological and ecosystem hydrological functioning in cloud forest settings. Finally, critical areas for future research are highlighted to further improve our understanding of the linkages between leaf- and ecosystem-level processes and fluxes.

    The design, operation, and properties of the Finnish Geodetic Institute Field Goniospectrometer (FIGIFIGO) are presented. FIGIFIGO is a portable instrument for the measurement of surface Bidirectional Reflectance Factor (BRF) for samples with diameters of 10 – 50 cm. A set of polarising optics enable the measurement of linearly polarised BRF over the full solar spectrum (350 – 2,500 nm). FIGIFIGO is designed mainly for field operation using sunlight, but operation in a laboratory environment is also possible. The acquired BRF have an accuracy of 1 – 5% depending on wavelength, sample properties, and measurement conditions. The angles are registered at accuracies better than 2°. During 2004 – 2008, FIGIFIGO has been used in the measurement of over 150 samples, all around northern Europe. The samples concentrate mostly on boreal forest understorey, snow, urban surfaces, and reflectance calibration surfaces. PMID:22412342

  2. The ash in forest fire affected soils control the soil losses. Part 2. Current and future research challenges

    Ash distribution on soil surface and impacts on soil properties received a great attention in recently (Pereira et al., 2010; Pereira et al., 2013). Ash it is a highly mobile material that can be easily transported wind, especially in severe wildland fires, where organic matter is reduced to dust, due the high temperatures of combustion. In the immediate period after the fire, ash cover rules soil erosion as previous researchers observed (Cerdà, 1998a; 1998b) and have strong influence on soil hydrological properties, such as water retention (Stoof et al. 2011 ) and wettability (Bodi et al., 2011). Ash it is also a valuable source of nutrients important for plant recuperation (Pereira et al., 2011; Pereira et al., 2012), but can act also as a source contamination, since are also rich in heavy metals (Pereira and Ubeda, 2010). Ash has different physical and chemical properties according the temperature of combustion, burned specie and time of exposition (Pereira et al., 2010). Thus this different properties will have different implications on soil properties including erosion that can increase due soil sealing (Onda et al. 2008) or decrease as consequence of raindrop impact reduction (Cerdà and Doerr, 2008). The current knowledge shows that ash has different impacts on soil properties and this depends not only from the type of ash produced, but of the soil properties (Woods and Balfour, 2010). After fire wind and water strong redistribute ash on soil surface, increasing the vulnerability of soil erosion in some areas, and reducing in others. Understand this mobility is fundamental have a better comprehension about the spatial and temporal effects of ash in soil erosion. Have a better knowledge about this mobility is a priority to future research. Other important aspects to have to be assessed in the future are how ash particulates percolate on soil and how ash chemical composition is important to induce soil aggregation and dispersion. How soil micro topography have implications on ash spatial distribution and if soil micro topography changes with time? What the factors that controls it? What it is the impact of ash in vegetation recuperation and the implications of this recover in ash spatial distribution? We need studies with better spatial and temporal resolution, especially in the immediate period after the fire, when the major spatial and temporal changes on ash distribution and impacts occur. Based on high level research conducted by Artemi Cerdà and others, our future research will be focused in these and other aspects in order to have a better knowledge about the impacts of ash on post-fire spatio-temporal erosion.

    1980-08-01

    Tropical forests constitute about half of the world's forest and are characterized by rapid rates of organic matter turnover and high storages of organic matter. Tropical forests are considered to be one of the most significant terrestrial elements in the equation that balances the carbon cycle of the world. As discussed in the paper by Tosi, tropical and subtropical latitudes are more complex in terms of climate and vegetation composition than temperate and boreal latitudes. The implications of the complexity of the tropics and the disregard of this complexity by many scientists is made evident in the paper by Brown and Lugo which shows that biomass estimates for tropical ecosystems have been overestimated by at least 100%. The paper by Brown shows that that rates of succession in the tropics are extremely rapid in terms of the ability of moist and wet forests to accumulate organic matter. Yet, in arid tropical Life Zones succession is slow. This leads to the idea that the question of whether tropical forests are sinks or sources of carbon must be analyzed in relation to Life Zones and to intensities of human activity in these Zones. The paper by Lugo presents conceptual models to illustrate this point and the paper by Tosi shows how land uses in the tropics also correspond to Life Zone characteristics. The ultimate significance of land use to the question of the carbon balance in a large region is addressed in the paper by Detwiler and Hall.

    While the quality of raw cow milk in Finland is known for its high hygienic standard, with the national average total bacterial count being below 10(4) CFU/mL annually, the prevalence of pathogenic bacteria in Finnish raw milk is underreported. The aim of this study was to determine the occurrence of Listeria monocytogenes, thermophilic Campylobacter spp., Salmonella spp., stx-positive Escherichia coli (STEC), coagulase-positive staphylococci, Yersinia spp., and Bacillus cereus group in raw cow milk samples collected from bulk tanks at 183 Finnish farms. Additionally, the hygienic quality of the milk was studied by determining the total bacterial and E. coli counts. L. monocytogenes was detected in 5.5% of the milk samples, with concentrations varying from <1 to 30 CFU/mL. Thermophilic Campylobacter spp. or Salmonella spp. were not detected in any of the samples. STEC with Shiga toxin-encoding stx2 was detected in 2.7% of the samples. Yersinia enterocolitica was detected in 7.7% of the samples; however, all isolates were negative for ail, suggesting that they were non-pathogenic. Coagulase-positive staphylococci were detected in 34.4% of the samples, with an average concentration of 25 CFU/mL in the positive samples. Members of the B. cereus group were detected in 20.8% of the samples, with an average concentration of 1 CFU/mL in the positive samples. No relationship was detected between E. coli or the total bacterial count and the presence of pathogenic bacteria, which suggests that pathogens can be present also in farms with excellent production hygiene. Although the concentration of pathogenic bacteria in fresh raw milk was mainly relatively low, it should be borne in mind that some of the pathogenic bacteria can survive and multiply at refrigeration temperatures and may cause a disease with a very low infectious dose. Thus, consumption of raw milk and related products poses a potential risk for food poisoning. PMID:23373473

  12. Variability within the 10-Year Pollen Rain of a Seasonal Neotropical Forest and Its Implications for Paleoenvironmental and Phenological Research

    2013-01-01

    Tropical paleoecologists use a combination of mud-water interface and modern pollen rain samples (local samples of airborne pollen) to interpret compositional changes within fossil pollen records. Taxonomic similarities between the composition of modern assemblages and fossil samples are the basis of reconstructing paleoclimates and paleoenvironments. Surface sediment samples reflect a time-averaged accumulation of pollen spanning several years or more. Due to experimental constraints, modern pollen rain samples are generally collected over shorter timeframes (1–3 years) and are therefore less likely to capture the full range of natural variability in pollen rain composition and abundance. This potentially biases paleoenvironmental interpretations based on modern pollen rain transfer functions. To determine the degree to which short-term environmental change affects the composition of the aerial pollen flux of Neotropical forests, we sampled ten years of the seasonal pollen rain from Barro Colorado Island, Panama and compared it to climatic and environmental data over the same ten-year span. We establish that the pollen rain effectively captured the strong seasonality and stratification of pollen flow within the forest canopy and that individual taxa had variable sensitivity to seasonal and annual changes in environmental conditions, manifested as changes in pollen productivity. We conclude that modern pollen rain samples capture the reproductive response of moist tropical plants to short-term environmental change, but that consequently, pollen rain-based calibrations need to include longer sampling periods (≥7 years) to reflect the full range of natural variability in the pollen output of a forest and simulate the time-averaging present in sediment samples. Our results also demonstrate that over the long-term, pollen traps placed in the forest understory are representative samples of the pollen output of both canopy and understory vegetation. Aerial pollen traps, therefore, also represent an underutilized means of monitoring the pollen productivity and reproductive behavior of moist tropical forests. PMID:23320089

    Tropical paleoecologists use a combination of mud-water interface and modern pollen rain samples (local samples of airborne pollen) to interpret compositional changes within fossil pollen records. Taxonomic similarities between the composition of modern assemblages and fossil samples are the basis of reconstructing paleoclimates and paleoenvironments. Surface sediment samples reflect a time-averaged accumulation of pollen spanning several years or more. Due to experimental constraints, modern pollen rain samples are generally collected over shorter timeframes (1-3 years) and are therefore less likely to capture the full range of natural variability in pollen rain composition and abundance. This potentially biases paleoenvironmental interpretations based on modern pollen rain transfer functions. To determine the degree to which short-term environmental change affects the composition of the aerial pollen flux of Neotropical forests, we sampled ten years of the seasonal pollen rain from Barro Colorado Island, Panama and compared it to climatic and environmental data over the same ten-year span. We establish that the pollen rain effectively captured the strong seasonality and stratification of pollen flow within the forest canopy and that individual taxa had variable sensitivity to seasonal and annual changes in environmental conditions, manifested as changes in pollen productivity. We conclude that modern pollen rain samples capture the reproductive response of moist tropical plants to short-term environmental change, but that consequently, pollen rain-based calibrations need to include longer sampling periods (≥7 years) to reflect the full range of natural variability in the pollen output of a forest and simulate the time-averaging present in sediment samples. Our results also demonstrate that over the long-term, pollen traps placed in the forest understory are representative samples of the pollen output of both canopy and understory vegetation. Aerial pollen traps, therefore, also represent an underutilized means of monitoring the pollen productivity and reproductive behavior of moist tropical forests. PMID:23320089

    Consumption and handling of chicken meat are well-known risk factors for acquiring campylobacteriosis. This study aimed to describe the Campylobacter jejuni population in Finnish chickens and to investigate the distribution of C. jejuni genotypes on Finnish chicken farms over a period of several years. We included 89.8% of the total C. jejuni population recovered in Finnish poultry during 2004, 2006, 2007, 2008, and 2012 and used multilocus sequence typing (MLST) and pulsed-field gel electrophoresis (PFGE) to characterize the 380 isolates. The typing data was combined with isolate information on collection-time and farm of origin. The C. jejuni prevalence in chicken slaughter batches was low (mean 3.0%, CI95% [1.8%, 4.2%]), and approximately a quarter of Finnish chicken farms delivered at least one positive chicken batch yearly. In general, the C. jejuni population was diverse as represented by a total of 63 sequence types (ST), but certain predominant MLST lineages were identified. ST-45 clonal complex (CC) accounted for 53% of the isolates while ST-21 CC and ST-677 CC covered 11% and 9% of the isolates, respectively. Less than half of the Campylobacter positive farms (40.3%) delivered C. jejuni-contaminated batches in multiple years, but the genotypes (ST and PFGE types) generally varied from year to year. Therefore, no evidence for a persistent C. jejuni source for the colonization of Finnish chickens emerged. Finnish chicken farms are infrequently contaminated with C. jejuni compared to other European Union (EU) countries, making Finland a valuable model for further epidemiological studies of the C. jejuni in poultry flocks.

    The purposes of the study were to determine how "an optimal herd" would be structured with respect to its calving pattern, average herdlife and calving interval, and to evaluate how sensitive the optimal solution was to changes in input prices, which reflected the situation in Finland in 1998. The study used Finnish input values in an optimization model developed for dairy cow insemination and replacement decisions. The objective of the optimization model was to maximize the expected net present value from present and replacement cows over a given decision horizon. In the optimal solution, the average net revenues per cow were highest in December and lowest in July, due to seasonal milk pricing. Based on the expected net present value of a replacement heifer over the decision horizon, calving in September was optimal. In the optimal solution, an average calving interval was 363 days and average herdlife after first calving was 48.2 months (i.e., approximately 4 complete lactations). However, there was a marked seasonal variation in the length of a calving interval (it being longest in spring and early summer) that can be explained by the goal of having more cows calving in the fall. This, in turn, was due to seasonal milk pricing and higher production in the fall. In the optimal solution, total replacement percentage was 26, with the highest frequency of voluntary culling occurring at the end of the year. Seasonal patterns in calving and replacement frequencies by calendar month and variation in calving interval length or herdlife did not change meaningfully (< 1%-2% change in the output variables) with changes in calf, carcass or feed prices. When the price of a replacement heifer decreased, average herdlife was shorter and replacement percentage increased. When the price increased, the effect was the opposite. PMID:10965569

    Radiation and Nuclear Safety Authority (STUK), Helsinki, Finland and Sandia National Laboratories (SNL), working under the Finnish Support Program to IAEA Safeguards and the United States Department of Energy (DOE) funded International Remote Monitoring Program (Task FIN E 935), have undertaken a joint effort to demonstrate the use of remote monitoring for environmental air sampling and safeguards applications. The results of the task will be used by the IAEA to identify the feasibility, cost-effectiveness, reliability, advantages, and problems associated with remote environmental monitoring. An essential prerequisite for a reliable remote air sampling system is the protection of samples against tampering. Means must be developed to guarantee that the sampling itself has been performed as designed and the original samples are not substituted with samples produced with other equipment at another site. One such method is to label the samples with an unequivocal tag. In addition, the inspection personnel must have the capability to remotely monitor and access the automated environmental air sampling system through the use of various sensors and video imagery equipment. A unique aspect to this project is the network integration of remote monitoring equipment with a STUK radiation monitoring system. This integration will allow inspectors to remotely view air sampler radiation data and sensor/image data through separate software applications on the same review station. A sensor network and video system will be integrated with the SNL developed Modular Integrated Monitoring System (MIMS) to provide a comprehensive remote monitoring approach for safeguards purposes. This field trial system is being implemented through a multiphase approach for use by STUK, SNL, and for possible future use by the IAEA.

    Background Breastfeeding attitudes are known to influence infant feeding but little information exists on the prenatal breastfeeding attitudes of parents. The purpose of this study was to describe Finnish parents' prenatal breastfeeding attitudes and their relationships with demographic characteristics. Methods The electronic Breastfeeding Knowledge, Attitude and Confidence scale was developed and 172 people (123 mothers, 49 fathers) completed the study. The data were analysed using factor analysis and nonparametric methods. Results Breastfeeding was regarded as important, but 54% of the respondents wanted both parents to feed the newborn. The mean rank values of breastfeeding attitudes differed significantly when parity, gender, education, age, breastfeeding history and level of breastfeeding knowledge were considered. The respondents who were expecting their first child, were 18-26 years old or had vocational qualifications or moderate breastfeeding knowledge had more negative feelings and were more worried about breastfeeding than respondents who had at least one child, had a higher vocational diploma or academic degree or had high levels of breastfeeding knowledge. Respondents with high levels of breastfeeding knowledge did not appear concerned about equality in feeding. Conclusions Both mothers and fathers found breastfeeding important. A father's eagerness to participate in their newborn's life should be included in prenatal breastfeeding counselling and ways in which to support breastfeeding discussed. Relevant information about breastfeeding should focus on the parents who are expecting their first child, those who are young, those with low levels of education or those who have gaps in breastfeeding knowledge, so that fears and negative views can be resolved.

    In Finland, a Government Decree on the Assessment of Soil Contamination and Remediation Needs has generated a need for reliable and readily accessible data on geochemical baseline concentrations in Finnish soils. According to the Decree, baseline concentrations, referring both to the natural geological background concentrations and the diffuse anthropogenic input of substances, shall be taken into account in the soil contamination assessment process. This baseline information is provided in a national geochemical baseline database, TAPIR, that is publicly available via the Internet. Geochemical provinces with elevated baseline concentrations were delineated to provide regional geochemical baseline values. The nationwide geochemical datasets were used to divide Finland into geochemical provinces. Several metals (Co, Cr, Cu, Ni, V, and Zn) showed anomalous concentrations in seven regions that were defined as metal provinces. Arsenic did not follow a similar distribution to any other elements, and four arsenic provinces were separately determined. Nationwide geochemical datasets were not available for some other important elements such as Cd and Pb. Although these elements are included in the TAPIR system, their distribution does not necessarily follow the ones pre-defined for metal and arsenic provinces. Regional geochemical baseline values, presented as upper limit of geochemical variation within the region, can be used as trigger values to assess potential soil contamination. Baseline values have also been used to determine upper and lower guideline values that must be taken into account as a tool in basic risk assessment. If regional geochemical baseline values are available, the national guideline values prescribed in the Decree based on ecological risks can be modified accordingly. The national geochemical baseline database provides scientifically sound, easily accessible and generally accepted information on the baseline values, and it can be used in various environmental applications.

    The article summarises the results of a multidisciplinary research project on the effectiveness of the Finnish EIA system. It examines the main strengths and weaknesses of EIA as a preventive and participatory environmental management tool. The study concludes that EIA has achieved a meaningful role in the environmental policy toolbox in Finland and has clearly enhanced the possibilities for high-quality environmental decision making. The research cites the liaison authority system as a clear strength of the Finnish EIA system in its enabling a single regional authority to specialise in and gain wide experience on EIA issues. In examining potential weaknesses of the regime, the article concludes that the key constraint on EIA effectiveness is inadequacy of the action-forcing mechanisms at the decision-making phase. The primary means to improve the effectiveness of EIA would be to strengthen the legal provisions on development consents. On the whole, the research indicates that the EU and Finnish legislation and guidance on environmental impact assessment provide a good framework for effective utilisation of the instrument.

    Three levels of organic matter removal (bole only; bole and crowns; and bole, crowns, and forest floor) and three levels of mechanical soil compaction (no compaction, moderate compaction, and severe soil compaction) were studied as they influence Douglas-fir (Pseudotsuga menziesii var. glauca (Beissn.) Franco) and western white pine (Pinus monticola Dougl. ex D. Don) seedlings following outplanting. Moderate and severe soil compaction significantly reduced nonmycorrhizal root tip abundance on both Douglas-fir and western white pine seedlings (p less than or equal to 0.05). Ectomycorrhizal root tip abundance was significantly reduced on Douglas-fir seedlings in severely compacted areas with bole and crowns and bole, crowns, and forest floor removed. Ectomycorrhizal diversity also was significantly reduced on Douglas-fir seedlings in all severely compacted areas.

    In order to test the feasibility of forest-land disposal of oil and gas waste waters, forest plots in Pennsylvania were treated with a one-time, dormant season application of gas-well brine equivalent to 1.52, 0.69 and 0.17 kg chloride per square meter. One growing season after treatment, little or no mortality of overstory trees had occurred due to treatment. Understory red maple and dogwood saplings suffered 30-40% mortality on the plot receiving 1.52 kg chloride per square meter. Chloride, barium, lead, arsenic, selenium and cadmium in excess of drinking water limits were found in soil water immediately after treatment. Concentrations of all elements, except selenium, declined to safe levels within three months after treatment in zero-tension soil lysimeter water samples.

    Instar development is recorded for the Douglas-fir tussock moth (Orgyia pseudot-sugata) for two different elevations in the Boise National Forest, Idaho, in 1991. The percentage of the population by instars is associated with accumulated degree-days after eclosion, which can be used to predict the proper timing for spray application. For all practical purposes, areas can be released for spraying when third instars are initially found.

  3. Managing the world's forests.

    1992-06-01

    Forests play a vital role in balancing natural systems: the stabilization of global climate and the management of water and land. 30% of the earth's total land area is forested. 66% of the tropical moist forests are in Latin America and the remainder in Africa and Asia. 75% of tropical dry forests are in Africa. Temperate forests are primarily in developed countries. Deforestation and misuse of forests occurs primarily in developing countries at significant social, economic, and environmental costs. Losses have occurred in fuelwood, fodder, timber, forest products, biological diversity, habitats, genetic materials for food and medicine. The World Bank's evolving role in forestry is briefly described. Agreement has not been reached among people or nations about the most appropriate means to balance conservation and development goals. The challenge is to stabilize existing forests and increase forest planting. The causes of forest degradation must be understood. Direct causes include agricultural encroachment, cattle ranching, fuelwood gathering, commercial logging, and infrastructure development. These direct causes are driven by economic, social, and political forces: market and policy failures, population growth, and poverty. The market failures include: 1) the lack of clearly defined property rights on forest resources for now and the future, 2) the conflict between individual and societal needs, 3) the difficulty in placing a value on nonmarket environmental services and joint products, and 4) the separation between private and social costs. The solution is action at the local, national, and global levels. Countries must establish forest policy. The existing government incentives which promote deforestation must be changed. For example, concession policy and royalty systems must be corrected; explicit and implicit export subsidies on timber and forest products must be stopped. Private incentives must be established to promote planting of trees, practicing preservation, and setting up sustainable management systems. Property rights must be clearly defined and land use policies must spell out forest use patterns. A global strategy for forest management is needed for conservation, protection, reforestation, agricultural and rural development, sustainable use, and research with funding. PMID:12285662

    Greater forest diversity is needed in the lodgepole pine forest cover type--particularly, along and east of the Continental Divide in Montana--if large-scale losses from cyclical bark beetle outbreaks and subsequent wildfires are to be reduced. Three species were compared to lodgepole pine in a test of mixed-species planting in three ecological habitat types of the lodgepole pine type. Differences in seedling survival, condition, and growth were observed among species and among habitat types by the fifth year after planting. The results indicate Englemann spruce and Douglas-fir can be used to attain mixed-species stands by interplanting naturally regenerated lodgepole pine seedling stands. Western larch probably can succeed only when planted in moist Douglas-fir, spruce, or the warmer subalpine fir habitat types east of the Continental Divide. Because of greater frost tolerance, western larch x alpine larch hybrids are promising for increasing forest diversity in some of the colder subalpine fir habitat types.

  7. Water, Energy and Carbon Balance Research: Recovery Trajectories For Oil Sands Reclamation and Disturbed Watersheds in the Western Boreal Forest

    The Oil Sand Region (OSR) of North-Central Alberta exists within the sub-humid Boreal Plains (BP) ecozone, with a slight long-term moisture deficit regime. Despite this deficit, the BP is comprised of productive wetland and mixed wood (aspen and conifer dominated) forests. Reclamation activities are now underway at a large number of surface mining operations in the OSR, where target ecosystems are identified, soil prescriptions placed and commercial forest species planted. Some watersheds have been created that now contain wetlands. However, recent work in the BP suggests that over time wetlands supply moisture for the productivity of upland forests. Thus, water use of reclaimed forests is going to be critical in determining the sustainability of these systems and adjacent wetlands, and whether in time, either will achieve some form of equivalent capability that will allow for certification by regulators. A critical component in the success of any reclamation is that sufficient water is available to support target ecosystems through the course of natural climate cycles in the region. Water Use Efficiency (WUE), which links photosynthesis (GEP) with water use (Evapotranspiration (ET)), provides a useful metric to compare ecosystems and evaluate their utilization of resources. In this study, 41 site years of total growing season water and carbon flux data over 8 sites (4 reclamation, 4 regeneration) were evaluated using eddy covariance micrometeorological towers. WUE shows clear discrimination among ecosystem types as aspen stands assimilate more carbon per unit weight of water than conifers. WUEs also change with time as ecosystems become more effective at transpiring water through plant pathways compared with bare-soil evaporation, which allows an assessment of ability to limit water loss without carbon uptake. In addition, clonal rooting systems allow aspen forests to recover quicker after disturbance than reclamation sites in terms of their WUE. For reclamation sites, there is considerable variability in GEP and ET associated with vegetation establishment, with enhanced ET losses over-riding any significant changes in C uptake, suggesting that long-term mine water management must consider ecosystem pathways if down-gradient wetlands and end-pit lakes are to be sustained.

  8. Forest pathology in Hawaii

    Native Hawaiian forests are characterised by a high degree of endemism, including pathogens as well as their hosts. With the exceptions of koa (Acacia koa Gray), possibly maile (Alyxia oliviformis Gaud.), and, in the past, sandalwood (Santalum spp.), forest species are of little commercial value. On the other hand, these forests are immensely important from a cultural, ecological, and evolutionary standpoint. Forest disease research was lacking during the mid-twentieth century, but increased markedly with the recognition of ohia (Metrosideros polymorpha Gaud.) decline in the 1970s. Because many pathogens are themselves endemic, or are assumed to be, having evolved with their hosts, research emphasis in natural areas is on understanding host-parasite interactions and evolutionary influences, rather than disease control. Aside from management of native forests, attempts at establishing a commercial forest industry have included importation of several species of pine, Araucaria, and Eucalyptus as timber crops, and of numerous ornamentals. Diseases of these species have been introduced with their hosts. The attacking of native species by introduced pathogens is problematic - for example, Armillaria mellea (Vahl ex Fr.) Que??l. on koa and mamane (Sophora chrysophylla (Salisb.) Seem.). Much work remains to be done in both native and commercial aspects of Hawaiian forest pathology.

    This study examines the ethnic identity experiences of second-generation Finnish immigrant youth in Canada. The study draws from interviews conducted among second-generation Finnish immigrant youth in Ottawa. How these individuals identify with the Finnish ethnic group and engage in ethnic culture may play a pivotal role in the continuance of Finnish culture in Canada. Therefore, it is necessary to understand not only whether second-generation Finnish immigrants identify with their ethnic group, but also how they do so. We found that the youth identified with their Finnish ethnicity on a symbolic level, participating occasionally in the local ethnic community, but not living within ethnic culture on a day-to-day basis. They identify strongly with being Canadian and have an appreciation of multiculturalism and contrast it with Finnish society when they visit Finland. PMID:20734563

    Exome sequencing studies in complex diseases are challenged by the allelic heterogeneity, large number and modest effect sizes of associated variants on disease risk and the presence of large numbers of neutral variants, even in phenotypically relevant genes. Isolated populations with recent bottlenecks offer advantages for studying rare variants in complex diseases as they have deleterious variants that are present at higher frequencies as well as a substantial reduction in rare neutral variation. To explore the potential of the Finnish founder population for studying low-frequency (0.5-5%) variants in complex diseases, we compared exome sequence data on 3,000 Finns to the same number of non-Finnish Europeans and discovered that, despite having fewer variable sites overall, the average Finn has more low-frequency loss-of-function variants and complete gene knockouts. We then used several well-characterized Finnish population cohorts to study the phenotypic effects of 83 enriched loss-of-function variants across 60 phenotypes in 36,262 Finns. Using a deep set of quantitative traits collected on these cohorts, we show 5 associations (p<5×10⁻⁸) including splice variants in LPA that lowered plasma lipoprotein(a) levels (P = 1.5×10⁻¹¹⁷). Through accessing the national medical records of these participants, we evaluate the LPA finding via Mendelian randomization and confirm that these splice variants confer protection from cardiovascular disease (OR = 0.84, P = 3×10⁻⁴), demonstrating for the first time the correlation between very low levels of LPA in humans with potential therapeutic implications for cardiovascular diseases. More generally, this study articulates substantial advantages for studying the role of rare variation in complex phenotypes in founder populations like the Finns and by combining a unique population genetic history with data from large population cohorts and centralized research access to National Health Registers.

    The key stakeholders of the Finnish engineering education collaborated during 2006-09 to reform the system of education, to face the challenges of the changing business environment and to create a national strategy for the Finnish engineering education. The work process was carried out using participatory work methods. Impacts of sustainable development (SD) on engineering education were analysed in one of the subprojects. In addition to participatory workshops, the core part of the work on SD consisted of a research with more than 60 interviews and an extensive literature survey. This paper discusses the results of the research and the work process of the Collaboration Group in the subproject of SD. It is suggested that enhancing systematic dialogue among key stakeholders using participatory work methods is crucial in increasing motivation and commitment in incorporating SD in engineering education. Development of the context of learning is essential for improving skills of engineering graduates in some of the key abilities related to SD: systemic- and life-cycle thinking, ethical understanding, collaborative learning and critical reflection skills. This requires changing of the educational paradigm from teacher-centred to learner-centred applying problem- and project-oriented active learning methods. PMID:22095059

    The stand exams conducted in western Montana over 50 years ago provide a valuable source of information on prefire suppression and preharvest condition of the region's forests. Of the early exam estimates of stand origin, 52 percent were within 20 years of estimates taken from stand exams conducted in the 1980's, and 73 percent were within 60 years. There was no significant bias toward either higher or lower age estimates. The early stand exam data can give an accurate estimate of stand age distributions over large areas.

  1. Susceptibility of volcanic ash-influenced soil in Northern Idaho to mechanical compaction. Forest Service research note

    SciTech Connect

    Page-Dumroese, D.S.

    1993-02-01

    Timber harvesting and mechanical site preparation can reduce site productivity if they excessively disturb or compact the soil. Volcanic ash-influenced soils with low undisturbed bulk densities and rock content are particularly susceptible. The study evaluates the effects of harvesting and site preparation on changes in the bulk density of ash-influenced forest soils in northern Idaho. Three different levels of surface organic matter were studied. Soil samples were taken before and after harvesting to determine the extent and depth of compaction. Soil bulk densities increased significantly after extensive compaction from site preparation, especially when little logging slash and surface organic matter were left on the soil surface. As site preparation intensity increased, bulk density increased significantly at greater depths in the soil profile. Although ash-influenced soils have naturally low bulk densities, they can easily be compacted to levels that limit growth. The experimental site has been designated as part of the Forest Service's national long-term site productivity study into the impacts of organic matter depletion and soil compaction on stand development.

    The role of organic and minerogenic acidity in controlling pH levels in Finnish rivers was studied by measuring total organic carbon (TOC) and non-marine sulphate (*SO(4)) concentrations in river water of the main river basins and their sub-basins. The basins are located along a latitudinal gradient (60 degrees N to 69 degrees N) and cover 297,322 km(2), 88% of the total area of Finland. The basins are predominately covered by coniferous forests and peatlands, and are located in areas with low sulphate deposition (80-430 mg S m(-2) a(-1)). The proportion of the basin covered by forests on mineral soils ranges from 29 to 64% and the proportion of peatlands from 3 to 60%. The percentage of peatland is highest in northern Finland (28-60%), whereas the proportion of forests on mineral soils increases towards the south. The majority of the agricultural land is located in southern and western Finland. *SO(4) concentrations were positively correlated with the proportion of agricultural land in the basin. Moreover, the percentage of peatlands had a positive correlation with the concentrations of TOC and organic anion. High peatland proportion and high TOC and organic anion concentrations decreased pH values in the river water, whereas no correlation between *SO(4) concentrations and pH was observed. The average organic anion concentration exceeded the average *SO(4) concentration in river water in 17 basins out of the 86 studied basins. The organic anion-dominated areas were situated in northern basins, reflecting the high extent of peatlands in these areas. *SO(4) dominated in southern Finland and in western coastal areas, where the extent of agricultural land, acid sulphate soils and the deposition of sulphate is highest.

  3. Investigating the spatial expression of millennial-scale Holocene climate changes: a multi-proxy lake sediment approach, Finnish Lapland

    2012-12-01

    Recent research has identified global Holocene climate instability. Oscillations at c. 2500 year intervals, identified in ocean and ice core records, are thought to be driven by solar variation. The North Atlantic thermohaline circulation (THC), a regulator of climate, oscillates with quasi-periodicities of c. 1500 years, the cause and spatial expression of which is uncertain. This project investigates how these subtle oscillations influenced the climate of northern Scandinavia through high-resolution, multi-proxy analysis (diatoms, isotope geochemistry, organic content, particle size, biogenic silica) of a lacustrine sediment sequence in Northern Finland. The resulting high-resolution, multi-proxy climate record clarifies the role of the THC in driving terrestrial climate change in this region. A 1.99m sediment core was extracted from Sirrajärvi, Northern Finnish Lapland in March 2012. Lake Sirrajävri (69.761619oN, 26.892815oE) is located 208 m.a.s.l. and lies at the boreal forest-alpine tundra ecotone. It is surrounded by low alpine heaths and isolated stands of birch (Betula pubescens spp. tortuosa). The lake is situated within a nature reserve, and <4km to Kevo subarctic research station, which houses a meteorological station with >50 yrs. of observations. The lake, which is 0.182 km2 in area and 11.2m deep at the centre, is ice covered between Sept. and May. The duration of lake ice cover is the main influencing factor on lake physio- chemistry and thus diatom ecology. The lake is hydrologically open and δ18O analysis of its waters (-11.2‰) predominantly reflects the mean annual weighted isotopic composition of precipitation. The core has been dated at 11160 yrs BP at 195cm and 2810 yrs BP at 69cm. In addition, sediment was collected from 30 lakes along a north-south transect in Finland in July 2012 to form the basis of a diatom-based transfer function, used to identify the major influencing variable(s) on diatom species assemblages which, in turn, is used in a quantitative reconstruction. In addition, monthly monitoring of Lake Sirrajävri ice cover and diatom population dynamics (ongoing since March 2011) further informs palaeoenvironmental interpretation. The resulting high-resolution, multiproxy (diatom, δ18Odiatom, δ13Corganic, C/N, particle size, organic content) palaeoclimate reconstruction provides a much-needed additional record in an area dominated by a complex relationship between the North Atlantic THC and regional terrestrial climate.

    Forest fires in Canton Ticino (Switzerland) are very complex phenomena. Meteorological data can explain some occurrences of fires in time, but not necessarily in space. Using anthropogenic and geographical feature data with the random forest algorithm, this study tries to highlight factors that most influence the fire-ignition and to identify areas under risk. The fundamental scientific problem considered in the present research deals with an application of random forest algorithms for the analysis and modeling of forest fires patterns in a high dimensional input feature space. This study is focused on the 2,224 anthropogenic forest fires among the 2,401 forest fire ignition points that have occurred in Canton Ticino from 1969 to 2008. Provided by the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL), the database characterizes each fire by their location (x,y coordinates of the ignition point), start date, duration, burned area, and other information such as ignition cause and topographic features such as slope, aspect, altitude, etc. In addition, the database VECTOR25 from SwissTopo was used to extract information of the distances between fire ignition points and anthropogenic structures like buildings, road network, rail network, etc. Developed by L. Breiman and A. Cutler, the Random Forests (RF) algorithm provides an ensemble of classification and regression trees. By a pseudo-random variable selection for each split node, this method grows a variety of decision trees that do not return the same results, and thus by a committee system, returns a value that has a better accuracy than other machine learning methods. This algorithm incorporates directly measurement of importance variable which is used to display factors affecting forest fires. Dealing with this parameter, several models can be fit, and thus, a prediction can be made throughout the validity domain of Canton Ticino. Comprehensive RF analysis was carried out in order to 1) understand the importance of environmental features, 2) to assess the predictability of forest fires using environmental variables, and 3) to compare RF with other machine learning algorithms for this particular case study. Risk maps were plotted by estimating the burned area taking into account the environmental variables and according to the most relevant selected variables. Key words: Random Forest, classification and regression trees, forest fires, risk maps.

    2009-09-01

    ABSTRACTThe aim of this study was to examine what four-year-old children repair in their speech. For this purpose, conversational self-repairs (N=316) made by two typically developing Finnish-speaking children (aged 4 ; 8 and 4 ; 11) were examined. The data comprised eight hours of natural interactions videotaped at the children's homes. The tapes were analyzed using conversation analysis. The children made phonological, morphological, syntactic, lexical and non-linguistic self-repairs, and also inserted additional material into their utterances. Finnish-speaking children made more syntactic and fewer morphological self-repairs than the previous research on English-speaking children suggests. Furthermore, most self-repairs were found in talk during pretend play. In designing and engaging in such play, the children skilfully used self-repair to match their talk to meet the requirements of different interactive activities and co-participants. Finally, contextual analysis of children's self-repairs showed that these were also socially motivated, and not just related to slips or errors in speech. PMID:19079829

    On a medium site in northern California, a tanoak-mixed shrub community was given several treatments (manual release two and three times, a combination chainsaw and cut surface herbicide treatment, two foliar herbicides, and a tank mix of the two herbicides) to study its development in both a natural (control) and treated condition. The herbicides were 2,4-D, Garlon 3A, and Garlon 4, each applied two times. Survival of planted Douglas-fir seedlings was recorded for 11 years and growth was quantified for 9 years after the last treatment application. In addition to Douglas-fir, data are presented individually for the two most abundant species (tanoak and snowbrush), for greenleaf manzanita, and for the hardwood tree and shrubs combined. The treatment response data, cost information, and plant community relationships provides the forest land manager with knowledge on how to attain some specific plant communities in the future, and their developmental potentials.

    The authors investigated the distribution of biomass and nutrients in lodgepole pine (Pinus contorta var. murryana Dougl.) ecosystems on pumice soils in south-central Oregon. Sixty-three trees were sampled to develop equations for estimating dry weights of tree crowns, boles, bark, and coarse roots from diameter at breast height and height. The concentrations of total carbon, nitrogen, phosphorus, and sulfur were determined for each of these components. Biomass, nutrient concentrations, and nutrient contents of the associated vegetation, forest floor, woody debris, fine roots, and soil horizons also were determined. An example stand illustrates the use of these data for determining the effects of bole versus whole-tree harvesting on nutrient capital in a lodgepole pine ecosystem.

  9. Does Finnish hospital staff job satisfaction vary across occupational groups?

    PubMed Central

    2013-01-01

    Background Job satisfaction of staff is an essential outcome variable in research when describing the work environment of successful hospitals. Numerous studies have evaluated the topic, but few previous studies have assessed the job satisfaction of all staff in hospital settings. It is important to discover if there are any unsatisfied groups of people working in hospitals, the aspects they are unsatisfied with and why. The aim of this study was to evaluate job satisfaction of all staff working at a Finnish university hospital, identify differences in job satisfaction between staff groups, and explore the relationship between their self-evaluated quality of work and job satisfaction. Methods Data were collected from 1424 employees of the hospital using the web-based Kuopio University Job Satisfaction Scale survey instrument in autumn 2010. The research data were analysed by using SPSS 19.0 for Windows. Frequency and percentage distributions, as well as mean values, were used to describe the data. A non-parametric test (Kruskal–Wallis test) was used to determine the significance of differences in scores between different groups of staff members and between quality evaluations. Results The overall job satisfaction of the employees was good. They rated both motivating factors of their work and work welfare as excellent. The areas causing most dissatisfaction were work demands and participation in decision making. Physicians formed the most satisfied group, nurses and maintenance staff were the least satisfied, and office and administrative staff were fairly satisfied. Staff who rated the quality of work in their units as high usually also considered their job satisfaction to be excellent. Conclusions Every staff member has an influence on job satisfaction in her/his unit. A culture of participation should be developed and maintained in the units and the whole hospital to ensure that all staff feel they play important roles in the hospital. A university hospital is a complex, continuously changing work environment. Managers of the hospital should continuously evaluate job satisfaction and quickly react to the results gained.

  11. Employees' Motivation for SPI: Case Study in a Small Finnish Software Company

    NASA Astrophysics Data System (ADS)

    Valtanen, Anu; Sihvonen, Hanna-Miina

    In small software companies the resources available for SPI are often limited. With limited resources, the motivation of the employees becomes one of the key factors for SPI. In this article, the motivational factors affecting a small company's SPI efforts are discussed. In the research, we carried out interviews and a survey in a small Finnish software company considering the motivation towards SPI. The results are presented here and compared with earlier motivation research. There were differences revealed while comparing the motivating factors of smaller companies to those of larger ones. In large companies the focus seems to be on the business related motivators and in small ones the motivators related to comfortability of work are emphasized. Motivation survey and the interviews proved to be useful tools in planning the future SPI strategy. A lot of valuable information was discovered for planning and implementing the next steps of SPI.

    The purpose of this study was to research teachers' experiences of the English-Language-Taught Degree Programs in the health care sector of Finnish polytechnics. More specifically, the focus was on teachers' experiences of teaching methods and clinical practice. The data were collected from eighteen teachers in six polytechnics through focus group interviews. Content analysis was used to analyse the data. The results suggested that despite the positive interaction between students and teachers, choosing appropriate teaching methods provided a challenge for teachers, due to cultural diversity of students as well as to the use of a foreign language in tuition. Due to students' language-related difficulties, clinical practice was found to be the biggest challenge in the educational process. Staffs' attitudes were perceived to be significant for students' clinical experience. Further research using stronger designs is needed. PMID:21095046

    Although adenoviruses were identified as important respiratory pathogens many years ago, little information is available concerning the prevalence of different adenovirus serotypes, which are circulating and causing epidemics in Finnish military training centers. Over a period of five years from 2008 to 2012, 3577 respiratory specimens were collected from military conscripts presenting with symptoms compatible with acute respiratory tract infection. Upon initial testing for certain respiratory viruses by real-time PCR, 837 of these specimens were identified as adenovirus-positive. For 672 of these specimens, the serotype of the adenovirus responsible was successfully determined by DNA sequencing. Serotypes 1, 2, 3, and 4 were detected in 1, 3, 181, and 487 samples, respectively. Adenovirus epidemics were observed during each year of this study. Based on these findings, adenovirus vaccination should be considered for military conscripts in the Finnish Defence Forces. J. Med. Virol. 88:571-577, 2016. © 2015 Wiley Periodicals, Inc.

    1990-02-01

    Minerotrophic peatlands or fens in California's Sierra Nevada are small wet meadows surrounded by mixed conifer forest. The dynamics of vegetation change at the meadow edge and the ages and development of fens were investigated, in the Sagehen Creek Basin near Truckee, California, through the use of radiocarbon dating of peat, pollen studies, examination of processes of peat development and accumulation, stand age analysis of trees around peatlands, and evaluation of tree-ring variation. These approaches were used to evaluate both short- and long-term changes. Fens varied in age from more than 8000 years to less than 1000 years old. Results suggest that overall fen development proceeds rapidly, with peat buildup dependent upon adequate moisture supply. During fen development trees repeatedly invade and retreat from the fen edges. The timing of invasions appear unrelated to events such as human disturbance and climatic change. Instead, changes are most likely to result from alterations in groundwater supply in interaction with tree establishment, longevity, and water uptake.

    Forests are a defining feature for large areas of the Pacific northwestern United States from northern California to Alaska. Coniferous temperate rainforests in the western Cascade and coastal mountain ranges are appreciated for their aesthetic value and abundant natural resources. Few people recognize the riches beneath the forest floor; yet, soil is a key ecosystem component that makes each type of forest unique. Soils harbor immense biological diversity and control the release of water and nutrients that support life above ground. Understanding how carbon and nutrients cycle in forests, known as forest biogeochemistry, is crucial for evaluating forest productivity, composition, diversity, and change. At the U.S. Geological Survey (USGS) Forest and Rangeland Ecosystem Science Center, research in the Terrestrial Ecosystems Laboratory focuses on nutrient cycling in five themes: climate change, nutrition and sustainability, fire effects, restoration, and forest-stream linkages. This research is essential to understand the entire forest ecosystem and to use the best science available to make informed policy and management decisions.

    The global recession has forced the Finnish forest industry to carry out major restructuring activities. Employees have faced different kinds of restructuring, mainly aimed at reducing staff and production. Many studies have shown the negative consequences of restructuring on employee well-being by using negative, ill-health indicators. Our aim is to examine the extent to which change appraisal influences both the negative and positive aspects of work-related well-being among employees who continue working in the organization after the restructuring process. We also examine the role of different actors (top management, immediate supervisor, employees themselves) in how the change is appraised. The study investigated blue-collar employees working in the Finnish forest industry during a period of extensive transition (2008–2009). All six participating factories underwent restructuring between baseline and the follow-up survey (n=369). After adjustment for gender, age and baseline well-being, negative change appraisal increased the risk of experiencing more stress and less work enjoyment. Negative change appraisals thus also damaged the positive, motivational aspects of employee well-being. The results showed the importance of offering employees the opportunity to participate in the planning of changes related to their work as regards positive change appraisal. PMID:24975107

  4. Testing the effort-reward imbalance model among Finnish managers: the role of perceived organizational support.

    2008-04-01

    The present study is aimed at examining the combined effects of effort-reward imbalance (ERI), overcommitment (OVC), and perceived organizational support (POS) on turnover intentions and work engagement, among Finnish managers (n = 1,301). Consequently, the study contributes to the research literature by examining how the ERI-outcomes relationship was dependent simultaneously on OVC and POS. The results showed that ERI x OVC x POS interaction was significant only for turnover intentions. The ERI-turnover intentions relationship was strongest under conditions of high OVC and low POS. In addition, the relationship between ERI and decreased work engagement, especially dedication, was strengthened among overcommitted managers, compared to their less committed counterparts. Altogether, the results indicate that interventions aimed at reducing turnover intentions and increasing work engagement by increasing ERI should consider OVC and POS. PMID:18393581

  5. Children's Everyday Lives Shadowed by Stalking: Post separation Stalking Narratives of Finnish Children and Women.

    Nikupeteri, Anna; Laitinen, Merja

    2015-01-01

    This qualitative study discusses post separation stalking and its implications in children's everyday lives. Based on narratives of 13 Finnish children and 20 women, the research fills a gap in the knowledge regarding the psychosocial, emotional, and physical impacts of stalking on children when their mothers are stalked by a former partner. It identifies four forms of impact: (a) an atmosphere of fear and feelings of insecurity; (b) disguised acts of stalking and the father's performance of care, love, and longing; (c) exploitation of children in stalking; and (d) physical abuse, acts of violence, and threats of death. The findings indicate that stalking severely constrains children's everyday lives and strengthens, yet often distorts, the mother-child bond. The study concludes that in cases where mothers are stalked, professionals in the social and health services, law enforcement, and criminal justice should view the children, too, as victims and construct supportive social relationships for women and children facing threatening life situations.

    The Colville Study was developed in 1994 to identify and evaluate a series of management options for achieving ecosystem objectives in dense stands of small diameter trees while also producing wood products. The Colville National Forest selected the Rocky II Timber Sale as an example of this type of stand that needed management to achieve the following goals: (1) create late successional forest structure, (2) decrease forest health risk from fire, insects, and disease, (3) improve wildlife habitat by providing large green trees and snags, and (4) improve stand aesthetics by decreasing stand density. The Colville Study was divided into four technical focus areas: Silviculture and Ecology, Forest Operations, Timber Conversion, and Economics.

    In Turkey illegal cutting takes place, which cannot be controlled. Legal cuttings have also been done by several state forest enterprises. As a result, the amount of wood raw material produced by forest enterprises legally and by forest villagers illegally has exceeded the potential capacity of the forest. According to the research related to Macka and other Turkish state forests, the state forests have been decreasing day by day. This is because the amount of wood raw material taken from the forests has exceeded the production potential of the forest. That study concluded that the Macka and other Turkish forests will be exhausted after 64 and 67 years, respectively. This study also examined both establishing and exploiting energy forests near the forest villages and producing fuel briquettes manufactured using the residues of agriculture, forestry, and stock breeding to diminish the demand for illegal fuel wood cutting from the state forests.

  12. Protocol for a process-oriented qualitative evaluation of the Waltham Forest and East London Collaborative (WELC) integrated care pioneer programme using the Researcher-in-Residence model

    PubMed Central

    Eyre, Laura; George, Bethan; Marshall, Martin

    2015-01-01

    Introduction The integration of health and social care in England is widely accepted as the answer to fragmentation, financial concerns and system inefficiencies, in the context of growing and ageing populations with increasingly complex needs. Despite an expanding body of literature, there is little evidence yet to suggest that integrated care can achieve the benefits that its advocates claim for it. Researchers have often adopted rationalist and technocratic approaches to evaluation, treating integration as an intervention rather than a process. Results have usually been of limited use to practitioners responsible for health and social care integration. There is, therefore, a need to broaden the evidence base, exploring not only what works but also how integrated care can most successfully be implemented and delivered. For this reason, we are carrying out a formative evaluation of the Waltham Forest and East London Collaborative (WELC) integrated care pioneer programme. Our expectation is that this will add value to the literature by focusing on the processes by which the vision and objectives of integrated care are translated through phases of development, implementation and delivery from a central to a local perspective, and from a strategic to an operational perspective. Methods and analysis The qualitative and process-oriented evaluation uses an innovative participative approach—the Researcher-in-Residence model. The evaluation is underpinned by a critical ontology, an interpretive epistemology and a critical discourse analysis methodology. Data will be generated using interviews, observations and documentary gathering. Ethics and dissemination Emerging findings will be interpreted and disseminated collaboratively with stakeholders, to enable the research to influence and optimise the effective implementation of integrated care across WELC. Presentations and publications will ensure that learning is shared as widely as possible. The study has received ethical approval from University College London's Research Ethics Committee and has all appropriate NHS governance clearances. PMID:26546147

    Study Objectives: To identify risk factors for experiencing nightmares among the Finnish general adult population. The study aimed to both test whether previously reported correlates of frequent nightmares could be reproduced in a large population sample and to explore previously unreported associations. Design: Two independent cross-sectional population surveys of the National FINRISK Study. Setting: Age- and sex-stratified random samples of the Finnish population in 2007 and 2012. Participants: A total of 13,922 participants (6,515 men and 7,407 women) aged 25–74 y. Interventions: N/A. Measurements and results: Nightmare frequency as well as several items related to socioeconomic status, sleep, mental well-being, life satisfaction, alcohol use, medication, and physical well-being were recorded with a questionnaire. In multinomial logistic regression analysis, a depression-related negative attitude toward the self (odds ratio [OR] 1.32 per 1-point increase), insomnia (OR 6.90), and exhaustion and fatigue (OR 6.86) were the strongest risk factors for experiencing frequent nightmares (P < 0.001 for all). Sex, age, a self-reported impaired ability to work, low life satisfaction, the use of antidepressants or hypnotics, and frequent heavy use of alcohol were also strongly associated with frequent nightmares (P < 0.001 for all). Conclusions: Symptoms of depression and insomnia were the strongest predictors of frequent nightmares in this dataset. Additionally, a wide variety of factors related to psychological and physical well-being were associated with nightmare frequency with modest effect sizes. Hence, nightmare frequency appears to have a strong connection with sleep and mood problems, but is also associated with a variety of measures of psychological and physical well-being.

    Forested wetlands have important roles in global biogeochemical cycles, supporting freshwater and saltwater commercial fisheries, and in providing a place for wildlife of all kinds to flourish. Scientific attention towards these ecosystems has lagged with only a few comprehensive works on forested wetlands of the world. A major emphasis of this book is to develop unifying principles and data bases on the structure and function of forested wetlands, in order to stimulate scientific study of them. Wetlands are areas that are inundated or saturated by surface-water or ground-water, at such a frequency and duration that under natural conditions they support organisms adapted to poorly aerated and/or saturated soil. The strategy of classifying the conditions that control the structure and behavior of forested wetlands by assuming that the physiognomy and floristic composition of the system will reflect the total energy expenditure of the ecosystem; and the structural and functional characteristics of forested wetlands from different parts of the world are the major topics covered.

    The present article focuses on connections between part-time special education and the good results of Finnish students in PISA studies. After a brief summary of the comprehensive school system and special education in Finland, PISA results are analysed. The analysis shows that the relative amount of special education targeted at language problems is highest in Finland among those countries from which comparative statistics are available. The writers argue that this preventive language-oriented part-time special education is an important factor behind the good PISA results.

    Background Previous studies investigating neuropsychological functioning of children with autism spectrum disorder (ASD) have only analysed certain abilities, such as executive functions or language. While comprehensive assessment of the neuropsychological profile of children with ASD has been the focus of recent research, most of the published evidence originates from single centres. Though studies on differences in neuropsychological features of children with ASD across countries are essential for identifying different phenotypes of ASD, such studies have not been conducted. Objective Our goal was to assess the neuropsychological abilities of children with ASD in northern Finland and Egypt and to examine the effect of age and intelligence quotient (IQ) on these abilities. Design Selected verbal and non-verbal subtests of the neuropsychological assessment NEPSY were used to examine 88 children with ASD in northern Finland (n=54, age M=11.2, IQ M=117.1) and Egypt (n=34, age M=8.4, IQ M=96.6). Results Finnish ASD children scored significantly higher than their Egyptian counterparts on the verbal NEPSY subtests Comprehension of Instructions (p<0.001), Comprehension of Sentence Structure (p<0.01), Narrative Memory (p<0.001) and Verbal Fluency (p<0.05) and on the non-verbal NEPSY subtest Design Fluency (p<0.01). Finnish and Egyptian ASD children did not differ on the subtests Memory for Faces, Object Recognition and Object Memory. In addition, we found that age and verbal IQ can have significant influence on neuropsychological performance. Conclusions Our results suggest a possible cultural impact on verbal and visuomotor fluency. However, the ability to recognize and memorize objects and the disability to remember faces appear to be typical for ASD and culturally independent. PMID:26829278

    1994-01-01

    This project involves collaborative research with Stephen W. Pacala and Simon A. Levin of Princeton University to calibrate, test, and analyze models of heterogeneous forested landscapes containing a diverse array of habitats. The project is an extension of previous, NASA-supported research to develop a spatially-explicit model of forest dynamics at the scale of an individual forest stand (hectares to square kilometer spatial scales). That model (SORTIE) has been thoroughly parameterized from field studies in the modal upland environment of western Connecticut. Under our current funding, we are scaling-up the model and parameterizing it for the broad range of upland environments in the region. Our most basic goal is to understand the linkages between stand-level dynamics (as revealed in our previous research) and landscape-level dynamics of forest composition and structure.

    Climate response to anthropogenic land cover change happens more locally and occurs on a shorter time scale than the global warming due to increased GHGs. Over the second half of last Century, peatlands were vastly drained in Finland to stimulate forest growth for timber production. In this study, we investigate the biophysical effects of peatland forestation on near-surface climate conditions in Finland. For this, the regional climate model REMO, developed in Max Plank Institute (currently in Climate Service Center, Germany), provides an effective way. Two sets of 15-year climate simulations were done by REMO, using the historic (1920s; The 1st Finnish National Forest Inventory) and present-day (2000s; the 10th Finnish National Forest Inventory) land cover maps, respectively. The simulated surface air temperature and precipitation were then analyzed. In the most intensive peatland forestation area in Finland, the differences in monthly averaged daily mean surface air temperature show a warming effect around 0.2 to 0.3 K in February and March and reach to 0.5 K in April, whereas a slight cooling effect, less than 0.2 K, is found from May till October. Consequently, the selected snow clearance dates in model gridboxes over that area are advanced 0.5 to 4 days in the mean of 15 years. The monthly averaged precipitation only shows small differences, less than 10 mm/month, in a varied pattern in Finland from April to September. Furthermore, a more detailed analysis was conducted on the peatland forestation area with a 23% decrease in peatland and a 15% increase in forest types. 11 day running means of simulated temperature and energy balance terms, as well as snow depth were averaged over 15 years. Results show a positive feedback induced by peatland forestation between the surface air temperature and snow depth in snow melting period. This is because the warmer temperature caused by lower surface albedo due to more forest in snow cover period leads to a quicker and earlier snow melting. Meanwhile, surface albedo is reduced and consequently surface air temperature is increased. Additionally, the maximum difference from individual gridboxes in this area over 15 years of 11 day running means of daily mean surface air temperature reaches 2 K, which is four times as much as the maximum difference of 15-year regional average of that. This illustrates that the spring warming effect from peatland forestation in Finland is highly heterogeneous spatially and temporally.

    The core location of my research project was the Arabuko Sokoke Forest. The forest is located along the east coast of Kenya and belongs to the coastal forest zone of eastern Africa. The forest is considered a biodiversity hotspot, having many species being endemic to this habitat. The Arabuko Sokoke Forest is not a rainforest, like the Kakamega Forest in western Kenya, but a tropical dry forest. The objective of my research was to create a general checklist of the ant species collected in teh Arabuko Sokoke Forest in 2009. The general checklist of ant species will be used to document the differences between the three different forest habitat types (Cynometra, Brachystegia and mixed forest) and ant communities found within the forest, as well as the fauna found in those locations. The ants were collected using the leaf litter extraction method and were then mounted and idenified. The results from my research were that out of 73 specimens, there were 13 genera and 24 different species. Four of the 24 species have not been recorded for this forest before and one of the Tetramorium is likely to be a new species. The results also showed that the species diversity on the two transects are almost the same. There was very low overlap between the two transects as well: there were two shared species between the two different forest habitat types. For future work, there are still many undiscovered ant species in the Arabuko Sokoke Forest. In order to get a more complete faunal overview, more samples have to be collected from different parts of the forest. To do this, the canopy ant fauna might offer additional species that were not collected in the leaf litter samples.

    Winter navigation is a complex but common operation in north-European sea areas. In Finnish waters, the smooth flow of maritime traffic and safety of vessel navigation during the winter period are managed through the Finnish-Swedish winter navigation system (FSWNS). This article focuses on accident risks in winter navigation operations, beginning with a brief outline of the FSWNS. The study analyses a hazard identification model of winter navigation and reviews accident data extracted from four winter periods. These are adopted as a basis for visualizing the risks in winter navigation operations. The results reveal that experts consider ship independent navigation in ice conditions the most complex navigational operation, which is confirmed by accident data analysis showing that the operation constitutes the type of navigation with the highest number of accidents reported. The severity of the accidents during winter navigation is mainly categorized as less serious. Collision is the most typical accident in ice navigation and general cargo the type of vessel most frequently involved in these accidents. Consolidated ice, ice ridges and ice thickness between 15 and 40cm represent the most common ice conditions in which accidents occur. Thus, the analysis presented in this article establishes the key elements for identifying the operation types which would benefit most from further safety engineering and safety or risk management development.

  2. Physics teacher education in Finland and reasons underlying the top scores of Finnish students on international assessments

    In Finland physics teachers have Master's degree in physics and pedagogical studies (60 cr). In addition they have introductory and intermediate studies (60 cr) in minor subjects, normally in mathematics and chemistry. The degree consists of 300 cr minimum and takes 5 years or more. In Bachelor studies (180 cr), almost identical in all Finnish universities, student teachers do the same physics courses than physicists (70 cr). Few exceptions can be found, e.g. in Joensuu we have two laboratory courses (5 cr) for student teachers. Part of pedagogical studies (25 cr) and some minor subject studies are included in Bachelor studies. Master studies (120 cr) differ more from university to university. Some universities do not make a difference between student teachers and forthcoming physicists but for instance the Universities of Joensuu and Helsinki offer several special courses for student teachers. These special courses include elements from different areas, e.g. the history of physics or the philosophy of physics, or the courses can concentrate on students' pre-knowledge or to foster students' conceptual and structural understanding of physics. In addition master's thesis can be done in the area of physics education. In summary, significant differences between universities can only be found in Master studies. However, there is no evidence that special courses for teachers produce better results than traditional master's physics courses. In fact most of the Finnish in-service physics teachers have done the traditional physics courses that do not include any influence from physics education research. Teacher education is surely one factor underlying the top scores of Finnish students. However, it is not only one and many other reasons can also be presented. )

    Based on the forest inventory data and single tree biomass model, the forest biomass in the sampling plots in Changbai Mountain forest region was calculated, and, by using the estimated forest biomass from four periods' remote sensing data and based on high accuracy remote sensing models, the changes of regional forest biomass were analyzed. In the meanwhile, the driving factors such as meteorological factors, management factors, and socio-economic factors that caused forest biomass change were selected by bootstrap method, and the driving model of forest biomass change in different time period was set up by using partial least-squares method. The Variable Importance in Projection (VIP) values representing the importance of each of the factors affecting the forest biomass change in study region were calculated. The results showed that the influence of human activity factors (VIP values) on Changhai Mountain forest biomass changes was less than that of natural factors, suggesting that the national forest protection policy for forest regions had played an obvious role. Our research broadened the content of forest biomass change driving analysis, and the introduction of calculating VIP value, which can quantitatively represent the influence of driving factors to forest biomass change, provided a new way for the quantitative analysis on forest biomass change.

    Global change is impacting forests worldwide, threatening biodiversity and ecosystem services including climate regulation. Understanding how forests respond is critical to forest conservation and climate protection. This review describes an international network of 59 long-term forest dynamics research sites (CTFS-ForestGEO) useful for characterizing forest responses to global change. Within very large plots (median size 25 ha), all stems ≥ 1 cm diameter are identified to species, mapped, and regularly recensused according to standardized protocols. CTFS-ForestGEO spans 25 °S-61 °N latitude, is generally representative of the range of bioclimatic, edaphic, and topographic conditions experienced by forests worldwide, and is the only forest monitoring network that applies a standardized protocol to each of the world's major forest biomes. Supplementary standardized measurements at subsets of the sites provide additional information on plants, animals, and ecosystem and environmental variables. CTFS-ForestGEO sites are experiencing multifaceted anthropogenic global change pressures including warming (average 0.61 °C), changes in precipitation (up to ± 30% change), atmospheric deposition of nitrogen and sulfur compounds (up to 3.8 g N m(-2) yr(-1) and 3.1 g S m(-2) yr(-1)), and forest fragmentation in the surrounding landscape (up to 88% reduced tree cover within 5 km). The broad suite of measurements made at CTFS-ForestGEO sites makes it possible to investigate the complex ways in which global change is impacting forest dynamics. Ongoing research across the CTFS-ForestGEO network is yielding insights into how and why the forests are changing, and continued monitoring will provide vital contributions to understanding worldwide forest diversity and dynamics in an era of global change.

    Bioaerosols (microbes, dust and endotoxins) and volatile organic compounds (VOCs) were determined in the working air of a drum composting plant treating source-separated catering waste. Different composting activities at the Oulu drum composting plant take place in their own units separated by modular design and constructions. Important implication of this is that the control room is a relatively clean working environment and the risk of exposure to harmful factors is low. However, the number of viable airborne microbes was high both in the biowaste receiving hall and in the drum composting hall. The concentration (geometric average) of total microbes was 21.8 million pcs/m3 in the biowaste receiving hall, 13.9 million pcs/m3 in the drum composting hall, and just 1.4 million pcs/m3 in the control room. Endotoxin concentrations were high in the biowaste receiving hall and in the drum composting hall. The average (arithmetic) endotoxin concentration was over the threshold value of 200 EU/m3 in both measurement locations. In all working areas, the average (arithmetic) dust concentrations were in a low range of 0.6-0.7 mg/m3, being below the Finnish threshold value of 5 mg/m3. In the receiving hall and drum composting hall, the concentrations of airborne microbes and endotoxins may rise to levels hazardous to health during prolonged exposure. It is advisable to use a respirator mask (class P3) in these areas. Detected volatile organic compounds were typical compounds of composting plants: carboxylic acids and their esters, alcohols, ketones, aldehydes, and terpenes. Concentrations of VOCs were much lower than the Finnish threshold limit values (Finnish TLVs), many of the quantified compounds exceeded their threshold odour concentrations (TOCs). Primary health effects due VOCs were not presumable at these concentrations but unpleasant odours may cause secondary symptoms such as nausea and hypersensitivity reactions. This situation is typical of composting plants where the workers are exposed to dozens of VOCs simultaneously. The odour units (OU/m3) were measured using olfactometer. The numbers were 23,000 OU/m3 at the output end of the composting drum and 6300 OU/m3 in the exhaust pipe. Inside the composting hall, the number of odour units was 500 and 560 OU/m3. PMID:15869986

    In their Finnish National Spatial Strategy 2010-2015 the Finland's Ministry of Agriculture and Forestry delineated e.g. that spatial data skills should support citizens everyday activities and facilitate decision-making and participation of citizens. Studies also predict that open data, particularly open spatial data, would create, when fully realizing their potential, a 15% increase into the turnovers of Finnish private sector companies. Finnish libraries have a long tradition of serving at the heart of Finnish information society. However, with the emerging possibilities of educating their users on open spatial data a very few initiatives have been made. The National Survey of Finland opened its data in 2012. Finnish technology university libraries, such as Aalto University Library, are open environments for all citizens, and seem suitable of being the first thriving entities in educating citizens on open geospatial data. There are however many obstacles to overcome, such as lack of knowledge about policies, lack of understanding of geospatial data services and insufficient know-how of GIS software among the personnel. This framework examines the benefits derived from an international collaboration between Purdue University Libraries and Aalto University Library to create local strategies in implementing open spatial data education initiatives in Aalto University Library's context. The results of this international collaboration are explicated for the benefit of the field as a whole.

    Both the United States and New Zealand are doing research in forest biotechnology and much of the interest is in speedy propagation from seed to mature tree. A number of propagation techniques are discussed, such as tissue culture, the culture of tissue from mature trees and somatic embryo genesis. Much of the tissue culture work has been done on radiata pine. Field testing results are considered. The aims and the advantages of forest biotechnology are discussed under the following headings. 1) Disease resistance: research is being carried out on a loblolly pine which would be resistant to fusiform rust. 2) Animal feed: some trees have been discovered to have lower lignin content and similar cellulose and hemicellulose to alfalfa. 3) Specialty chemicals: terpenes, in the tree resin, could be turned into hormones, drugs and other chemicals: the genetic system for the overall biosynthesis of terpenes has been studied. 4) Herbicide resistance. The resistance to glyphosate in poplars is being studied. In conclusion, further research into forest species, using molecular biology is considered essential.

    This book examines the many complex and sensitive issues relating to wildland fires. Beginning with an overview of the fires of 1980s, the book discusses the implications of continued drought and considers the behavior of wildland fires, from ignition and spread to spotting and firestorms. Topics include the effects of weather, forest fuels, fire ecology, and the effects of fire on plants and animals. In addition, the book examines firefighting methods and equipment, including new minimum impact techniques and compressed air foam; prescribed burning; and steps that can be taken to protect individuals and human structures. A history of forest fire policies in the U.S. and a discussion of solutions to fire problems around the world completes the coverage. With one percent of the earth's surface burning every year in the last decade, this is a penetrating book on a subject of undeniable importance.

    Habitat loss causes population declines, but the mechanisms are rarely known. In the European Boreal Zone, loss of old forest due to intensive forestry is suspected to cause declines in forest-dwelling raptors by reducing their breeding performance. We studied the boreal breeding habitat and habitat-associated breeding performance of the northern goshawk (Accipiter gentilis), common buzzard (Buteo buteo) and European honey buzzard (Pernis apivorus). We combined long-term Finnish bird-of-prey data with multi-source national forest inventory data at various distances (100-4000 m) around the hawk nests. We found that breeding success of the goshawk was best explained by the habitat within a 2000-m radius around the nests; breeding was more successful with increasing proportions of old spruce forest and water, and decreasing proportions of young thinning forest. None of the habitat variables affected significantly the breeding success of the common buzzard or the honey buzzard, or the brood size of any of the species. The amount of old spruce forest decreased both around goshawk and common buzzard nests and throughout southern Finland in 1992-2010. In contrast, the area of young forest increased in southern Finland but not around hawk nests. We emphasize the importance of studying habitats at several spatial and temporal scales to determine the relevant species-specific scale and to detect environmental changes. Further effort is needed to reconcile the socioeconomic and ecological functions of forests and habitat requirements of old forest specialists. PMID:26422684

  14. Methods and practices used in incident analysis in the Finnish nuclear power industry.

    According to the Finnish Nuclear Energy Act it is licensee's responsibility to ensure safe use of nuclear energy. Radiation and Nuclear Safety Authority (STUK) is the regulatory body responsible for the state supervision of the safe use of nuclear power in Finland. One essential prerequisite for the safe and reliable operation of nuclear power plants is that lessons are learned from the operational experience. It is utility's prime responsibility to assess the operational events and implement appropriate corrective actions. STUK controls licensees' operational experience feedback arrangements and implementation as part of its inspection activities. In addition to this in Finland, the regulatory body performs its own assessment of the operational experience. Review and investigation of operational events is a part of the regulatory oversight of operational safety. Review of operational events is done by STUK basically at three different levels. First step is to perform a general review of all operational events, transients and reactor scram reports, which the licensees submit for information to STUK. The second level activities are related to the clarification of events at site and entering of events' specific data into the event register database of STUK. This is done for events which meet the set criteria for the operator to submit a special report to STUK for approval. Safety significance of operational events is determined using probabilistic safety assessment (PSA) techniques. Risk significance of events and the number of safety significant events are followed by STUK indicators. The final step in operational event assessment performed by STUK is to assign STUK's own investigation team for events deemed to have special importance, especially when the licensee's organisation has not operated as planned. STUK launches its own detail investigation once a year on average. An analysis and evaluation of event investigation methods applied at STUK, and at the two Finnish nuclear power plant operators Teollisuuden Voima Oy (TVO) and Fortum Power and Heat Oy (Fortum) was carried out by the Technical Research Centre (VTT) on request of STUK at the end of 1990s. The study aimed at providing a broad overview and suggestions for improvement of the whole organisational framework to support event investigation practices at the regulatory body and at the utilities. The main objective of the research was to evaluate the adequacy and reliability of event investigation analysis methods and practices in the Finnish nuclear power industry and based on the results to further develop them. The results and suggestions of the research are reviewed in the paper and the corrective actions implemented in event investigation and operating experience procedures both at STUK and at utilities are discussed as well. STUK has developed its own procedure for the risk-informed analysis of nuclear power plant events. The PSA based event analysis method is used to assess the safety significance and importance measures associated with the unavailability of components and systems subject to Technical Specifications. The insights from recently performed PSA based analyses are also briefly discussed in the paper. PMID:15231350

    At the moment, Finnish oral health care is undergoing many changes. Little attention has been paid to issues of organisational culture and communication in Finnish oral health care. Yet the question of culture is of primary importance for changes in an organisation and for planning and reconstructing the rational functioning of an organisation. The purpose of this paper is to examine Finnish public oral health care within a theoretical framework of organisational culture and to identify the various cultural traits that appear to characterise Finnish oral health care. Using a cultural point of view, we develop an orientation for understanding more profoundly and specifically the processes concerning the functioning and change of oral health care. PMID:15481692

    Forest health ecological risk assessment is an important factor in forest resources management. In this paper, we selected forest fire, forest disease-pest disasters and acid rain as main risk sources, described the risk resources by probability, intensity and distributing, and mapped each risk source. The endpoints were the damages that the risk acceptor might and these damages might cause ecosystems' organization and function changing under the uncertainty risk sources. Endpoints of forest might compose of productivity descent, reducing biodiversity, forest degrading, forest ecological function declining, furthermore, forest disappearing. We described exposure in terms of intensity, space, and time. In the exposure and hazard analysis, we used fragile index to show frangibility or resistibility (resistibility is reverse to frangibility), and analyzed the damages by different risk sources. Risk assessment and management was the integrated phase of the research. Because of the spatial heterogeneity of risk sources, all risk index were overlaid in the China map by GIS, which divided the region into 30 ecological risk sub-zones (provinces), according to risk index of each risk sub-zone, and the forest in China was divided into six levels of risk zones. In every level of risk zones, we also put forward the countermeasures for forest health ecological risk management. The result of assessment could provide scientific basis for forest management.

  1. Hydrological recovery in forested landscapes (Invited)

    2013-12-01

    Considerable effort has been expended trying to understand how forest landscapes respond hydrologically to natural (e.g. fire) or anthropogenic (e.g. harvesting) disturbance. However, comparable emphasis has not been placed on assessing whether and how these landscapes recover from such disturbances. Hydrological recovery can be defined as the restoration of hydrologic characteristics (e.g. evapotranspiration rates, soil infiltrability) of disturbed and managed sites to a near pre-disturbance condition. Improved and sustainable use of forest resources depends on better knowledge of the spatial and temporal aspects of recovery of hydrologic properties and processes affected by forest disturbance. This enhanced understanding is particularly pressing given such issues as the implications of climate change for forest ecosystems and the transition of forest management in many regions from forestry for wood, pulp and paper to forest harvesting for biofuels, where the potential magnitude of forest disturbances and hydrological recovery times are largely unknown. Initial studies of hydrological recovery focused on streamflow changes at the basin scale due to forest disturbance and regeneration, while more recent work has examined a variety of hydrologic properties and processes across a range of scales. The differing approaches that are currently used to assess hydrological recovery will be examined, drawing examples of recovery rates of various hydrologic processes in different forest landscapes. Counter-intuitive findings of this research will be highlighted, efforts to incorporate models of hydrological recovery into forest management strategies will be reviewed, and important avenues for future research will be discussed.

  2. Managed forest reserves: preserving diversity

    2003-01-01

    Background As part of the Northwest Forest Plan, large areas have been designated on many federal forests in western Oregon to provide critical habitat for plants and animals that are associated with old-growth habitat. Some of the structural characteristics often considered typical of old forests include large-diameter overstory trees, large standing and fallen dead trees, and one or more understory layers (Figure 1). However, not all of these areas are currently in old-growth conditions. Many of them contain young (<40 years), uniformly dense Douglas-fir stands that regenerated after timber harvest. The original management goal for these stands was to produce high yields of timber and associated wood products. With implementation of the Northwest Forest Plan in 1994, the management objective shifted to accelerating development of old-growth characteristics by enhancing structural and biological diversity of these areas. A major challenge today is how to promote these structural characteristics in younger stands. Researchers have been asking if lessons can be learned from the development of our current old growth and applied to management of younger stands. Dr. John Tappeiner and his university and agency research partners are helping to answer this question by examining the differences in development between old-growth and young stands in western Oregon. Understanding how the structure of these old forests developed may provide a model for management of young stands, especially when the management goal is to provide habitat for species associated with older forests.

    Fire is an important natural and anthropogenic factor in the dynamics of the boreal forest system. The ecological and environmental impacts of boreal fires depend on fire weather, fuel availability, fire behavior and history of sand development (frequency and size of fires and other biotic and abiotic disturbances, influence of surrounding landscape on successional developments). About 70% of the global boreal forest is in Eurasia, almost all of it in the Russian Federation. It is estimated that in years with high fire danger up to ca. 10 million ha of forest and other land in the Russian Federation are affected by fire. The demand for reliable information on the role of natural and anthropogenic fire and the necessity to develop adequate fire management systems is basically due to globally increasing concerns about (1) impacts of boreal wildfires on atmosphere and climate, (2) changing utilization and ecologically destructive practices in boreal forestry, and (3) possible consequences of global climate change on the boreal forest system.

    Forests are an influential component of the global carbon cycle and strongly influence Earth's climate. Climate change is altering the dynamics of forests globally, which may result in significant climate feedbacks. Forest responses to climate change entail both short-term ecophysiological responses and longer-term directional shifts in community composition. These short- and long-term responses of forest communities to climate change may be better understood through long-term monitoring of large forest plots globally using standardized methodology. Here, we describe a global network of forest research plots (CTFS/ForestGEO) of utility for understanding forest responses to climate change and consequent feedbacks to the climate system. CTFS/ForestGEO is an international network consisting of 51 sites ranging in size from 2-150 ha (median size: 25 ha) and spanning from 25°S to 52°N latitude. At each site, every individual > 1cm DBH is mapped and identified, and recruitment, growth, and mortality are monitored every 5 years. Additional measurements include aboveground productivity, carbon stocks, soil nutrients, plant functional traits, arthropod and vertebrates monitoring, DNA barcoding, airborne and ground-based LiDAR, micrometeorology, and weather monitoring. Data from this network are useful for understanding how forest ecosystem structure and function respond to spatial and temporal variation in abiotic drivers, parameterizing and evaluating ecosystem and earth system models, aligning airborne and ground-based measurements, and identifying directional changes in forest productivity and composition. For instance, CTFS/ForestGEO data have revealed that solar radiation and night-time temperature are important drivers of aboveground productivity in moist tropical forests; that tropical forests are mixed in terms of productivity and biomass trends over the past couple decades; and that the composition of Panamanian forests has shifted towards more drought-tolerant species. Ongoing monitoring will be vital to understanding global forest dynamics in an era of climate change.

  7. Uncertainty in future water supplies from forests: hydrologic effects of a changing forest landscape

    Forests account for 33 percent of the U.S. land area, process nearly two-thirds of the fresh water supply, and provide water to 40 percent of all municipalities or about 180 million people. Water supply management is becoming more difficult given the increasing demand for water, climate change, increasing development, changing forest ownership, and increasingly fragmented laws governing forest and watershed management. In 2006, the US National Research Council convened a study on the present understanding of forest hydrology, the hydrologic effects of a changing forest landscape, and research and management needs for sustaining water resources from forested landscapes. The committee concluded that while it is possible to generate short-term water yield increases by timber harvesting, there are a variety of reasons why active forest management has only limited potential to sustainably increase water supplies. These include the short-term nature of the increases in most environments, the timing of the increases, the need for downstream storage, and that continuing ground- based timber harvest can reduce water quality. At the same time, past and continuing changes in forest structure and management may be altering water supplies at the larger time and space scales that are of most interest to forest and water managers. These changes include the legacy of past forest management practices, particularly fire suppression and clearcutting; exurban sprawl, which permanently converts forest land to nonforest uses; effects of climate change on wildfires, insect outbreaks, forest structure, forest species composition, snowpack depth and snowmelt; road networks; and changes in forest land ownership. All of these changes have the potential to alter water quantity and quality from forests. Hence, the baseline conditions that have been used to estimate sustained water yields from forested watersheds may no longer be applicable. Stationarity also can no longer be assumed for the long-term control watersheds that have served as the cornerstone for most watershed-scale forest hydrology studies. The net result is that forest and water managers are facing greater uncertainty about future water supplies, water quality, and aquatic ecosystems, and their planning must consider a broader range of future scenarios than in the past. In this presentation, we outline a way forward for the research community to address the challenging questions of the future related to forests and water, and we chart a path for the involvement of various stakeholder groups to engage in water resources research, monitoring and policy formation.

    Over the past 20 years, the focus of forest science on air pollution has moved from forest decline to a holistic framework of forest health, and from the effects on forest production to the ecosystem services provided by forest ecosystems. Hence, future research should focus on the interacting factorial impacts and resulting antagonistic and synergistic responses of forest trees and ecosystems. The synergistic effects of air pollution and climatic changes, in particular elevated ozone, altered nitrogen, carbon and water availability, must be key issues for research. Present evidence suggests air pollution will become increasingly harmful to forests under climate change, which requires integration amongst various stressors (abiotic and biotic factors, including competition, parasites and fire), effects on forest services (production, biodiversity protection, soil protection, sustained water balance, socio-economical relevance) and assessment approaches (research, monitoring, modeling) to be fostered.

    Amid widespread reports of deforestation, some nations have nevertheless experienced transitions from deforestation to reforestation. In a causal relationship, the Forest Identity relates the carbon sequestered in forests to the changing variables of national or regional forest area, growing stock density per area, biomass per growing stock volume, and carbon concentration in the biomass. It quantifies the sources of change of a nation's forests. The Identity also logically relates the quantitative impact on forest expanse of shifting timber harvest to regions and plantations where density grows faster. Among 50 nations with extensive forests reported in the Food and Agriculture Organization's comprehensive Global Forest Resources Assessment 2005, no nation where annual per capita gross domestic product exceeded $4,600 had a negative rate of growing stock change. Using the Forest Identity and national data from the Assessment report, a single synoptic chart arrays the 50 nations with coordinates of the rates of change of basic variables, reveals both clusters of nations and outliers, and suggests trends in returning forests and their attributes. The Forest Identity also could serve as a tool for setting forest goals and illuminating how national policies accelerate or retard the forest transitions that are diffusing among nations.

  11. Lakes in the Finnish Eurowaternet: status and trends.

    2003-07-01

    The Eurowaternet is a monitoring network designed to cover all European countries, with the overall objective of obtaining timely, quantitative and comparative information on the status of inland waters so that their key environmental problems can be defined, quantified and monitored. Finland launched the Eurowaternet for lakes in 2000. The network was set up according to guidelines of the European Environment Agency (EEA) and was based on national, regional and local monitoring programmes. It includes 253 lake sites, divided into the following groups by, for example, their loading background and size: (i) reference sites, (ii) point-source loading (impact) sites, (iii) agricultural sites, (iv) representative sites, i.e. lakes <100 km(2) with typical water quality in the catchment and (v) lake deep sites in large lakes (>100 km(2)). We examined the water quality and its development during 1976-2001 in these groups, using data from surface and near-bottom water layers at summer and winter stagnation. In addition, the representativeness of the network was evaluated. Summer mean concentrations of total P (TP) during 1990-2001 in surface water were (i) 6.8+/-1.8 microg 1(-1) in reference lakes, (ii) 24+/-5 microg 1(-1) in lakes affected by point loading, (iii) 58+/-32 microg l(-1) in agricultural lakes, (iv) 14+/-2.2 microg l(-1) in representative lakes and (v) 11+/-2.1 microg l(-1) in large lakes. Comparison with reference lakes revealed major impact of human activities on TP and total N (TN)-and consequently on chlorophyll a (a-chl) and transparency-in all other groups, especially agricultural lakes. Decreasing TP and increasing O(2) trends were found at impact sites, reflecting water protection measures taken in pulp and paper mills and municipalities. More surprisingly, we found increasing alkalinity trends in all but agricultural sites and decreasing NO(2)-N+NO(3)-N (NO(x)-N) trends particularly in pelagic areas of large lakes. Comparison of water quality in Eurowaternet lakes with those in randomly sampled lakes (Finnish Lake Survey) revealed that the Eurowaternet covers the entire range of concentrations of TP, TN and conductivity in Finnish lakes, but <1-km(2), eutrophic and/or brown water lakes are underrepresented. Only 0.2% of a total of 13114 small lakes (0.1-1 km(2)) are included in the annual monitoring program of the Eurowaternet. PMID:12812729

  12. Breeding for better eye health in Finnish blue fox (Vulpes lagopus).

    The frequency of eye infections in the Finnish blue fox population has increased during the past decade. Eye infection may incur economic losses to producers due to reduced selection intensity, but ethical aspects need to be considered as well because eye infection can be quite painful and reduce animal well-being. The purpose of this study was to determine the potential for genetic selection against susceptibility to eye infection. The data were collected from 2076 blue foxes at the MTT fur animal research station. Genetic parameters were estimated using single- and multiple-trait animal models. The heritability estimate for eye infection was analysed as a binary trait (EYE) and was moderate (0.240.07). EYE had a moderate antagonistic genetic correlation (-0.490.20) with grading density (thick underfur). The genetic correlation of EYE with grading size or body condition score was estimated without precision, but all size traits had a low antagonistic phenotypic correlation with EYE. Our results suggest that there is genetic variance in susceptibility to EYE, indicating that eye health can be improved through selection. The current recommendation is that the sick animals should be culled immediately. If more efficient selection is needed, the selection index and multiple-trait animal models can be applied in breeding for better eye health. PMID:26077003

Those forests are located around the world in different climate zones effecting widely on atmospheric composition via new particle formation. The Boreal forests solely cover one third of the forests extent and are one of the largest vegetation environments, forming a circumpolar band throughout the northern hemisphere continents, with a high potential to affect climate processes [1]. In order to more fully understand the possible climatic effects of the forests, the properties of secondary organic aerosols (SOA) in varying conditions (e.g. a change in meteorological parameters or in the concentrations of biogenic and antropogenic trace gases) need to be better known. In this study, we applied the UFO-TDMA (ultrafine organic tandem differential mobility analyzer [2]) and the UFH-TDMA (ultrafine hygroscopicity tandem differential mobility analyzer [3]) methods parallel to shed light on the evolution of the nucleation and Aitken mode particle compositions (via physic-chemical properties) at a virgin boreal forest site in varying conditions. The measurements were carried out at Hyytiälä forest station in Northern Europe (Finland) during 15 spring nucleation events. We also carried out a statistical analysis using linear correlations in order to explain the variability in the composition behaviour of the particles during multiple nucleation events. The overall results show a clear anthropogenic influence on the nucleation and Aitken mode particle compositions during the events. The SO2/MTOP and NOx/MTOP (MTOP, monoterpene oxidation products) ratios explain most strongly the variation in the nucleation mode composition during clean and pollution-affected events, suggesting also the importance of organic sulfur compounds, in addition to other sulfur, nitrogen and organic compounds, in particle formation, composition and properties. During the cleanest events, MTOP explain significantly the time behaviour of the 10 nm particle composition with an estimated organic fraction of over 95%. [1] P.

    Tropical forests are global epicentres of biodiversity and important modulators of the rate of climate change. Recent research on deforestation rates and ecological changes within intact forests, both areas of recent research and debate, are reviewed, and the implications for biodiversity (species loss) and climate change (via the global carbon cycle) addressed. Recent impacts have most likely been: (i) a large source of carbon to the atmosphere, and major loss of species, from deforestation and (ii) a large carbon sink within remaining intact forest, accompanied by accelerating forest dynamism and widespread biodiversity changes. Finally, I look to the future, suggesting that the current carbon sink in intact forests is unlikely to continue, and that the tropical forest biome may even become a large net source of carbon, via one or more of four plausible routes: changing photosynthesis and respiration rates, biodiversity changes in intact forest, widespread forest collapse via drought, and widespread forest collapse via fire. Each of these scenarios risks potentially dangerous positive feedbacks with the climate system that could dramatically accelerate and intensify climate change. Given that continued land-use change alone is already thought to be causing the sixth mass extinction event in Earth's history, should such feedbacks occur, the resulting biodiversity and societal consequences would be even more severe.

    The overall objective of the Forest Ecosystem Dynamics (FED) research activity is to develop a better understanding of the dynamics of forest ecosystem evolution over a variety of temporal and spatial scales. Primary emphasis is being placed on assessing the ecosystem dynamics associated with the transition zone between northern hardwood forests in eastern North America and the predominantly coniferous forests of the more northerly boreal biome. The approach is to combine ground-based, airborne, and satellite observations with an integrated forest pattern and process model which is being developed to link together existing models of forest growth and development, soil processes, and radiative transfer.

    Communities, policy actors and conservationists benefit from understanding what institutions and land management regimes promote ecosystem services like carbon sequestration and biodiversity conservation. However, the definition of success depends on local conditions. Forests' potential carbon stock, biodiversity and rate of recovery following disturbance are known to vary with a broad suite of factors including temperature, precipitation, seasonality, species' traits and land use history. Methods like tracking over-time changes within forests, or comparison with "pristine" reference forests have been proposed as means to compare the structure and biodiversity of forests in the face of underlying differences. However, data from previous visits or reference forests may be unavailable or costly to obtain. Here, we introduce a new metric of locally weighted forest intercomparison to mitigate the above shortcomings. This method is applied to an international database of nearly 300 community forests and compared with previously published techniques. It is particularly suited to large databases where forests may be compared among one another. Further, it avoids problematic comparisons with old-growth forests which may not resemble the goal of forest management. In most cases, the different methods produce broadly congruent results, suggesting that researchers have the flexibility to compare forest conditions using whatever type of data is available. Forest structure and biodiversity are shown to be independently measurable axes of forest condition, although users' and foresters' estimations of seemingly unrelated attributes are highly correlated, perhaps reflecting an underlying sentiment about forest condition. These findings contribute new tools for large-scale analysis of ecosystem condition and natural resource policy assessment. Although applied here to forestry, these techniques have broader applications to classification and evaluation problems using crowdsourced or repurposed data for which baselines or external validations are not available.

    Media portrayals of older people, such as those in newspapers, both inform and reflect public attitudes. By becoming aware of culturally influenced attitudes about older people, and how these attitudes are reflected in the ways older people are viewed, treated, and cared for in society, the healthcare profession can better understand how to provide high-quality care. By applying an ethnographic approach in textual reality, this paper explores how newspaper articles focusing on health portray older people in society, using Finland as an example. The data consist of articles selected from three of the main Finnish daily newspapers during a 3-month period in the spring of 2012. The findings show that, overall, the society regards older people and their care as important. However, there were suggestions of paternalistic attitudes towards older people. Furthermore, the perceptions regarding different groups of older people could lead to the possibility of inequality. The media portrayals of older people worldwide seem to share similarities, although the findings of this study are particularly in accordance with the cultural attributes of the Nordic countries and societies.

    Mortality among workers in the Finnish pulp and paper industry was evaluated in a retrospective cohort study of 3520 workers who had been employed continuously for at least one year between 1945 and 1961. Six subcohorts were formed according to six work areas: sulphite, sulphate, paper, and board mills, maintenance department, and power plant. National mortality rates were used for comparison. The mortality of a cohort of 1290 sawmill workers was also studied in order to have a socially, geographically, and occupationally similar group without the exposures typical of the pulp and paper industry for comparison. Smoking habits were surveyed. Mortality was followed up until 31 December 1981. Overall mortality for the entire cohort did not differ from that expected (1044 obs, 1029.4 exp, SMR 101), but there was an excess of deaths from diseases of the circulatory system among the men (489 obs, 404.9 exp, SMR 121). This was due to the excess of deaths from ischaemic heart disease found among the men at the sulphite, sulphate, and paper mills, maintenance department, and power plant, but not at the sawmill. The existing smoking data did not explain this finding and it may therefore be associated with occupational exposures. PMID:3663525

    Sequence variation in mitochondrial DNA (mtDNA) may cause slight differences both in the functioning of the respiratory chain and in free radical production, and an association between certain mtDNA haplogroups and longevity has been suggested. In order to determine further the role of mtDNA in longevity, we studied the frequencies of mtDNA haplogroups and haplogroup clusters among elderly subjects and controls in a Finnish population. Samples were obtained from 225 persons aged 90-91 years (Vitality 90+) and from 400 middle-aged controls and 257 infants. MtDNA haplogroups were determined by restriction fragment length polymorphism. The haplogroup frequencies of the Vitality 90+ group differed from both those of the middle-aged controls ( P=0.01) and the infants ( P=0.00005), haplogroup H being less frequent than among the middle-aged subjects ( P=0.001) and infants ( P=0.00001), whereas haplogroups U and J were more frequent. Haplogroup clusters also differed between Vitality 90+ and both the middle-aged subjects ( P=0.002) and infants ( P=0.00001), the frequency of haplogroup cluster HV being lower in the former and that of UK and WIX being higher. These data suggest an association between certain mtDNA haplogroups or haplogroup clusters and longevity. Furthermore, our data appear to favour the presence of advantageous polymorphisms and support a role for mitochondria and mtDNA in the degenerative processes involved in ageing. PMID:12483296

    Forty scientists from the United States and Finland met last spring at a workshop to develop collaborative studies of magnetospheric-ionospheric coupling and to synthesize multiple ground-based and space-based data sets. The workshop also provided an opportunity to compare the output of new U.S. and Finnish Global Magnetohydrodynamic models with ground-based and satellite observations. Some of the missions and facilities that are providing new data within the United States and Finland include the Global Geospace Science/national Solar-Terrestrial Program Polar and Wind satellites, Interball, the Fast Auroral Snapshot Explorer, the Solar and Heliospheric Observatory, Ulysses, the Svalbard Radar, the new Super Dual Auroral Radar Network (SuperDARN) station, digital all sky cameras, and the Magnetosphere Imager (MI) array in Finland. The workshop began with a discussion of dayside magnetospheric-ionospheric coupling. Dayside ionospheric transient signatures were divided into three types: auroral forms and convection velocity spikes, magnetic and convection events, and twin convection vortices. The three classes differ in size, location, repetition rates, and Interplanetary Magnetic Field (IMF) dependencies. Scientists are addressing whether the transient classes are related, what the transients' role is compared to that of permanent cusp features, and how transients affect mag-netospheric energetics.

    The existence of familial carpal tunnel syndrome (FCTS) as a separate autonomic entity has been discussed during the last few years. In order to contribute with more data to the literature, we report here the results of clinical. electrophysiological, pathological and radiological studies performed in 5 patients belonging to the same Finnish pedigree. The disease appeared usually before the second decade with numbness and pain on the I--III digits. In most patients symptoms were unilateral but within 2 years they became bilateral. In all patients typical electrophysiological features of median nerve entrapment have been recorded. X-rays of the wrist showed narrow carpal tunnel in all patients. In all patients the possibility of having HNPP as well as familial amyloidosis has been excluded by molecular genetic and pathological studies. All patients underwent surgery and at postoperative stage symptoms were relieved or completely disappeared. Our study supports the theory that FCTS exists as a separate autonomic entity, therefore it is important in front of a sporadic case to investigate the family occurrence of CTS. PMID:11903093

    Three sugar beet herbicides, ethofumesate, phenmedipham and metamitron, are currently used on conventional sugar beet cultivation, while new varieties of herbicide resistant (HR) sugar beet, tolerant of glyphosate or glufosinate-ammonium, are under field testing in Finland. Little knowledge has so far been available on the adsorption of these herbicides to Finnish soils. The adsorption of these five herbicides was studied using the batch equilibrium method in 21 soil samples collected from different depths. Soil properties like organic carbon content, texture, pH and partly the phosphorus and oxide content of the soils were tested against the adsorption coefficients of the herbicides. In general, the herbicides studied could be arranged according to their adsorption coefficients as follows: glyphosate>phenmedipham>ethofumesate approximately glufosinate-ammonium>metamitron, metamitron meaning the highest risk of leaching. None of the measured soil parameters could alone explain the adsorption mechanism of these five herbicides. The results can be used in model assessments of risk for leaching to ground water resulting from weed control of sugar beet in Finland. PMID:14761694

    Media portrayals of older people, such as those in newspapers, both inform and reflect public attitudes. By becoming aware of culturally influenced attitudes about older people, and how these attitudes are reflected in the ways older people are viewed, treated, and cared for in society, the healthcare profession can better understand how to provide high-quality care. By applying an ethnographic approach in textual reality, this paper explores how newspaper articles focusing on health portray older people in society, using Finland as an example. The data consist of articles selected from three of the main Finnish daily newspapers during a 3-month period in the spring of 2012. The findings show that, overall, the society regards older people and their care as important. However, there were suggestions of paternalistic attitudes towards older people. Furthermore, the perceptions regarding different groups of older people could lead to the possibility of inequality. The media portrayals of older people worldwide seem to share similarities, although the findings of this study are particularly in accordance with the cultural attributes of the Nordic countries and societies.

    In countries like Finland, where forestry-drained peatlands sum up to 4.6 million ha, knowledge on their greenhouse gas (GHG) emissions is eagerly needed for both annual GHG reporting and when considering ways to mitigate the climate change. To get a good picture of variation in GHG fluxes in Finnish forestry-drained peatlands, this study aimed to cover the climatic and soil properties derived variation occurring in Finland. We measured both total (RTOT) and heterotrophic (RHET) soil respiration. Also the other possibly significant GHG:s, CH4 and N2O, were studied at the same study sites to make it possible to evaluate their significance in the GHG balance. We chose the 69 study sites so that the different site types of forestry-drained peatlands were equally represented in all parts of Finland. At each site, we measured RTOT on 5 vegetated plots and RHET on five trenched plots (roots cut, litter layer and ground vegetation removed) every 2-3 weeks in May-October 2007-2008. Annual values were calculated using an Arrhenius type nonlinear regression between R and peat temperature. CH4 and N2O samples were collected at 4 vegetated plot 5-7 times during the study and annual fluxes were interpolated. The dependency of annual CO2, CH4 and N2O fluxes on average May-October air temperature (Tas), tree stand stem volume (V), peat bulk density (BD), average May-October water table depth (WTa) and peat CN ratio (CN) was tested with linear and nonlinear regression models to find suitable variables for upscaling fluxes to country level. Both RTOT and RHET depended on several factors. A linear model with Tas, V, BD and WTa as independents explained 64.2% of RTOT and 62.5% of RHET. Information on V, BD (only limitedly) and Tas for upscaling is found in National Forest inventory (NFI) data and weather statistics. CH4 flux depended nonlinearly on WTa. WTa is not routinely measured in NFI, but can fairly well be substituted with V. N2O flux correlated nonlinearly with CN ratio. Information on CN for upscaling is available in a separate study conducted on NFI sites.

  11. Forest dynamics

    Frelich, Lee

    2016-01-01

    Forest dynamics encompass changes in stand structure, species composition, and species interactions with disturbance and environment over a range of spatial and temporal scales. For convenience, spatial scale is defined as individual tree, neighborhood, stand, and landscape. Whether a given canopy-leveling disturbance will initiate a sequence of development in structure with little change in composition or initiate an episode of succession depends on a match or mismatch, respectively, with traits of the dominant tree species that allow the species to survive disturbance. When these match, certain species-disturbance type combinations lock in a pattern of stand and landscape dynamics that can persist for several generations of trees; thus, dominant tree species regulate, as well as respond to, disturbance. A complex interaction among tree species, neighborhood effects, disturbance type and severity, landform, and soils determines how stands of differing composition form and the mosaic of stands that compose the landscape. Neighborhood effects (e.g., serotinous seed rain, sprouting, shading, leaf-litter chemistry, and leaf-litter physical properties) operate at small spatial extents of the individual tree and its neighbors but play a central role in forest dynamics by contributing to patch formation at stand scales and dynamics of the entire landscape. Dominance by tree species with neutral to negative neighborhood effects leads to unstable landscape dynamics in disturbance-prone regions, wherein most stands are undergoing succession; stability can only occur under very low-severity disturbance regimes. Dominance by species with positive effects leads to stable landscape dynamics wherein only a small proportion of stands undergo succession at any one time. Positive neighborhood effects are common in temperate and boreal zones, whereas negative effects are more common in tropical climates. Landscapes with positive dynamics have alternate categories of dynamics stabilized by high-severity and low-severity disturbance regimes. Contrary to prevailing ecological theory, systems with positive neighborhood effects can have similar levels of compositional stability across tree, stand, and landscape scales. Neighborhood effect theory can help explain responses of landscapes to large-scale land clearing and novel effects brought on by factors such as invasive species and deer overabundance.

    In Finland, shooting ranges are among the most common activities causing soil contamination. According to our study based on questionnaires and previous regional surveys, the total number of Finnish outdoor shooting ranges is between 2000 and 2500. Most of the ranges are small and only ca. 5% exceed 20 ha. Almost a third of the ranges can cause a groundwater pollution risk, while only few cause an immediate health risk. In the first instance, 50-60 shooting ranges identified as being high-risk areas should be investigated in detail. At present, the risk management options at Finnish shooting ranges are very limited. Hence, soil excavation combined with disposal is the most common remediation technique. Some of the remediation methods used in other countries have been proven unsuitable in Finnish conditions. Therefore, new, feasible, cost-effective and economical remediation technologies are needed. To exclude future contamination, a total ban of lead shot would be the most effective way. PMID:16458952

    Studies of the history and current status of forest resources in Northeast China have become important in discussions of sustainable forest management in the region. Prior to 1998, excessive logging and neglected cultivation led to a series of problems that left exploitable forest reserves in the region almost exhausted. A substantial decrease in the area of natural forests was accompanied by severe disruption of stand structure and serious degradation of overall forest quality and function. In 1998, China shifted the primary focus of forest management in the country from wood production to ecological sustainability, adopting ecological restoration and protection as key foci of management. In the process, China launched the Natural Forest Conversion Program and implemented a new system of Classification-based Forest Management. Since then, timber harvesting levels in Northeast China have decreased, and forest area and stocking levels have slowly increased. At present, the large area of low quality secondary forest lands, along with high levels of timber production, present researchers and government agencies in China with major challenges in deciding on management models and strategies that will best protect, restore and manage so large an area of secondary forest lands. This paper synthesizes information from a number of sources on forest area, stand characteristics and stocking levels, and forest policy changes in Northeastern China. Following a brief historical overview of forest harvesting and ecological research in Northeast China, the paper discusses the current state of forest resources and related problems in forest management in the region, concluding with key challenges in need of attention in order to meet the demands for multi-purpose forest sustainability and management in the future.

  8. Sustainable Forest Bioenergy Initiative

    SciTech Connect

    Breger, Dwayne; Rizzo, Rob

    2011-09-20

    In the state’s Electricity Restructuring Act of 1998, the Commonwealth of Massachusetts recognized the opportunity and strategic benefits to diversifying its electric generation capacity with renewable energy. Through this legislation, the Commonwealth established one of the nation’s first Renewable Energy Portfolio Standard (RPS) programs, mandating the increasing use of renewable resources in its energy mix. Bioenergy, meeting low emissions and advanced technology standards, was recognized as an eligible renewable energy technology. Stimulated by the state’s RPS program, several project development groups have been looking seriously at building large woody biomass generation units in western Massachusetts to utilize the woody biomass resource. As a direct result of this development, numerous stakeholders have raised concerns and have prompted the state to take a leadership position in pursuing a science based analysis of biomass impacts on forest and carbon emissions, and proceed through a rulemaking process to establish prudent policy to support biomass development which can contribute to the state’s carbon reduction commitments and maintain safeguards for forest sustainability. The Massachusetts Sustainable Forest Bioenergy Initiative (SFBI) was funded by the Department of Energy and started by the Department of Energy Resources before these contentious biomass issues were fully raised in the state, and continued throughout the substantive periods of this policy development. Thereby, while SFBI maintained its focus on the initially proposed Scope of Work, some aspects of this scope were expanded or realigned to meet the needs for groundbreaking research and policy development being advanced by DOER. SFBI provided DOER and the Commonwealth with a foundation of state specific information on biomass technology and the biomass industry and markets, the most comprehensive biomass fuel supply assessment for the region, the economic development impact associated with biomass usage, an understanding of forest management trends including harvesting and fuel processing methods, and the carbon profile of utilizing forest based woody biomass for the emerging biomass markets. Each of the tasks and subtasks have provided an increased level of understanding to support new directives, policies and adaptation of existing regulations within Massachusetts. The project has provided the essential information to allow state policymakers and regulators to address emerging markets, while ensuring forest sustainability and understanding the complex science on CO2 accounting and impacts as a result of biomass harvesting for power generation. The public at large and electricity ratepayers in Massachusetts will all benefit from the information garnered through this project. This is a result of the state’s interest to provide financial incentives to only biomass projects that demonstrate an acceptable carbon profile, an efficient use of the constrained supply of fuel, and the harvest of biomass to ensure forest sustainability. The goals of the Massachusetts Sustainable Forest Bioenergy Initiative as proposed in 2006 were identified as: increase the diversity of the Massachusetts energy mix through biomass; promote economic development in the rural economy through forest industry job creation; help fulfill the state’s energy and climate commitments under the Renewable Energy Portfolio Standard and Climate Protection Plan; assist the development of a biomass fuel supply infrastructure to support energy project demands; provide education and outreach to the public on the benefits and impacts of bioenergy; improve the theory and practice of sustainable forestry in the Commonwealth. Completed project activities summarized below will demonstrate the effectiveness of the project in meeting the above goals. In addition, as discussed above, Massachusetts DOER needed to make some modifications to its work plan and objectives during the term of this project due to changing public policy demands brought forth in the course of the public discourse on this topic. We found that some tasks needed to be adjusted to meet changed conditions. Shortly after the start of SFBI, DOER recognized that establishing demonstration plots within state owned lands was not possible as the state enacted a temporary freeze on all timber harvesting on state lands, to allow for the completion of an assessment of current impacts of this activity and time to develop prudent policies on land conservation. Even more significantly, the state’s energy and environmental Secretary asked DOER to place a “sustainability” criterion for biomass in the RPS regulations, and the passage of the landmark Global Warming Solutions Act in 2008 committed DOER to very carefully consider and assure that biomass energy supported by the RPS met carbon reduction thresholds aligned with the state’s reduction commitments. These needs led to some adjustment of the SFBI scope and objectives to meet the policy challenges. Most notably was the funding and commissioning of the report by the Manomet Center for Conservation Sciences which provided the sustainability and carbon impact framework necessary for DOER to move policy forward prudently. The “Manomet Study” has moved this emerging policy issue substantially forward, gained national and international significance, and provided a new look at how the forest sequesters carbon and the effect of the removal of growing stock for energy on future carbon sequestration and atmospheric flux. This activity provided information that supports the objectives of SFBI but to accommodate this work, several subtasks were combined and addressed within the framework of the Manomet research study. The expected outcomes of the SFBI include the development of biomass energy systems that support sustainable forest management, new investment in forestry and fuel supply infrastructure, biomass energy generation that contributes to greenhouse gas mitigation, and job creation in project development and operation and in the rural forestry sector.

    2009-12-01

    We examined how differences in local forest-management institutions relate to disparate anthropogenic forest disturbance and forest conditions among three neighboring montane forests in Tanzania under centralized, comanaged, or communal management. Institutional differences have been shaped by decentralization reforms. We conducted semistructured interviews with members of forest management committees, local government, and village households and measured anthropogenic disturbance, tree structure, and species composition in forest plots. We assessed differences in governance system components of local institutions, including land tenure, decision-making autonomy by forest users, and official and de facto processes of rule formation, monitoring, and enforcement among the three management strategies. We also assessed differences in frequencies of prohibited logging and subsistence pole cutting, and measures of forest condition. An adjacent research forest served as an ecological reference for comparison of forest conditions. Governance was similar for comanaged and centralized management, whereas communal managers had greater tenure security and decision-making autonomy over the use and management of their forest. There was significantly less illegal logging in the communal forest, but subsistence pole cutting was common across all management strategies. The comanaged forest was most disturbed by recent logging and pole cutting, as were peripheral areas of the larger centralized forest. This manifested in more degraded indicators of forest conditions (lower mean tree size, basal area, density of trees >or= 90 cm dbh, and aboveground biomass and higher overall stem density). Greater tenure security and institutional autonomy of the communal strategy contributed to more effective management, less illegal logging, and maintenance of good forest conditions, but generating livelihood benefits was a challenge for both decentralized strategies. Our results underscore the importance of well-designed institutional arrangements in forest management and illustrate mechanisms for improved forest governance and conservation in the context of Tanzanian decentralization reforms.

  10. Applicability of SPOT for forest management

    NASA Astrophysics Data System (ADS)

    Jaakkola, S. P.

    The recent applications of satellite remote sensing for forest management are reviewed mainly on the basis of European experience. The review is illustrated using results of the applied research during the first two years of SPOT-1 in orbit. The potential and limitations of satellite imagery, specific to SPOT, are discussed from the forestry point of view. Research results concerning forest cover type mapping, forest inventory and change monitoring - including the European forest decline - are reported. An evaluation of digital SPOT-data for forest inventory purposes in northern Sweden is reported in more detail. The original SPOT-data was preprocessed, integrated (PA + XS-bands) and filtered for texture extraction. A texture based algorithm was tested for finding logging roads. The timber stand delineation method developed combines image segmentation, classification of the segments and the final delineation of stands using an expert system. The results show that (1) the computer-aided forest mapping leads to acceptable forest management units, and (2) the manual stand delineation using digitally enhanced SPOT-data (color prints) coincides very well with the actual forest maps used for comparison. Finally, the potential applications of satellite remote sensing for forestry in the 1990's are outlined.

  13. Patterns of Forest Disturbance and Recovery Dynamics on Structure and Carbon Fluxes in New England Forests

    Forest disturbance and recovery strongly influence forest structure, function and services. Forest disturbance and recovery are critical mechanisms for transferring carbon between the land surface and the atmosphere, yet the role of forest disturbance within the terrestrial carbon cycle still remains uncertain and only recently have these events been accounted for within regional-scale and global carbon models. Adding ecological disturbance into biogeochemical models is noted as critical to estimating current and future carbon stocks and fluxes. This study used satellite-based observations of forest change, lidar derived structure data and a height structured ecosystem model to improve knowledge of disturbances role in carbon cycle by quantifying how forest disturbance and recovery vary at different spatial and temporal scales. Annual forest change maps from 1984-2010 were produced using the highly automated Vegetation Change Tracker (VCT) algorithm (Huang et al 2009). Mapped forest change was further broken down into land conversion (forest to non forest), severe disturbance (stand replacing), and non severe (partial clearing/ thinning). Areas of forest change were aggregated at different spatial scales and temporal scales and integrated into the Ecosystem Demography model (ED), a mechanistic model of forest ecosystem dynamics, to calculate changes in biomass and carbon fluxes. Forest structural data derived from NASA's Laser Vegetation Imaging Sensor (LVIS) was used to assess regrowth of forests and compare to ED's height and structure properties. Results in the New England Region show both spatial and temporal variation in area disturbed. The northern region encompassing Northern New Hampshire showed higher and more variable rates with an average annual rate of disturbance of approximately 0.5% (range 0.2- 08%) conversion/ non regeneration forest clearing range 0.02 -0.08%. While the southern averaged annual disturbance of 0.3% (ranged 0.2 - 0.5%) it had a much higher rate of conversion and showed had a positive trend in though time from 0.03- 0.18%.Within the state annual forest disturbance rates were on average 3 times higher outside of federally managed lands, which comprise 20 percent of NH forest lands. Incorporation of canopy height data has constrained model estimates of carbon stocks and annual net ecosystem production considerably with a strong relationship to in field measurements however the current coverage of lidar does not allow the same continuous monitoring provided by imagery thus a combination of the two tools may provide more useful then either alone. Results show that management is a major driver of forest change patterns and more research is needed to separate manmade from natural disturbance events. Results show that future research concerning the proportion of disturbance below VCT detection may be an important aspect of ecosystem modeling.

    Atmospheric aerosol composition was measured using a Single Particle Soot Photometer (SP2) in the Finnish Arctic during winter 2011-2012. The Sammaltunturi measurement site at the Pallas GAW (Global Atmosphere Watch) station receives air masses from different source regions including the Arctic Ocean and continental Europe. SP2 is a unique instrument that can give detailed information about mass distributions and mixing state of refractory black carbon (rBC). As expected, the measurements showed widely varying rBC mass concentrations (0-120 ng m-3), which were related to varying contributions of different source regions and aerosol removal processes. The log-normally distributed rBC core size was relatively constant with an average geometric mass mean diameter of 194 nm. On the average, the number fraction of particles containing rBC was 0.24 and the average rBC core size in these particles was half of the total size (coated to core diameter ratio was 2.0). These numbers mean that the core was larger and had a significantly thicker coating than in typical particles closer to their source regions. Comparison of the measured rBC mass concentration with that of the optically detected equivalent black carbon (eBC) showed a factor of five difference, which could not be fully explained without assuming that a part of the absorbing material is non-refractory. Finally, climate implications of five different rBC mixing state representations were quantified using the Mie approximation and simple direct radiative forcing efficiency calculations. These calculations showed that the observed mixing state (separate non-absorbing and coated rBC particles) means significantly lower warming effect or even a net cooling effect when compared with that of an homogenous aerosol containing the same amounts of rBC and non-absorbing material.

    This study aimed to assess the prevalence of smoking and snuff use in Finnish elite athletes. Of all the athletes (n = 494) financially supported by the National Olympic Committee, 446 completed a structured questionnaire (response rate 90.3 %) in 2002. A control group (n = 1504, response rate 80.2 %) comprised an age-matched sample from the population-based sample collected by the National Public Health Institute. Any smoking was reported by 11.4 % of the athletes (3.6 % daily and 7.8 % occasionally) and by 38.3 % of the controls (28.1 % and 10.2 %). After adjusting for age, sex, and education, OR (95 % CI) for any smoking was highest 0.42 (0.23 - 0.77) for athletes in skill-based events and lowest 0.06 (0.02 - 0.17) for endurance athletes as compared with controls. Snuff use was reported by 24.6 % of the athletes (9.6 % daily and 15.0 % occasionally) and by 3.7 % of the controls (1.8 % and 1.9 %). The adjusted OR (95 % CI) for any snuff use was highest 15.6 (9.55 - 25.6) for team-sport athletes and lowest 3.33 (1.54 - 7.21) for endurance athletes as compared with controls. Although snuff use in the general female population is rare, also female athletes did use snuff. Though prevalence of daily smoking among athletes was one-seventh of the respective figure for the general population, prevalence of daily snuff use was five-fold that of controls. Tobacco free elite athletes are valuable in health counselling because athletes are considered role models influencing their peers and the sport. Sport associations are challenged to ban all forms of tobacco. PMID:16802255

    A fine fraction (FF) was mined from two Finnish municipal solid waste (MSW) landfills in Kuopio (1- to 10-year-old, referred as new landfill) and Lohja (24- to 40-year-old, referred as old landfill) in order to characterize FF. In Kuopio the FF (<20mm) was on average 45±7% of the content of landfill and in Lohja 58±11%. Sieving showed that 86.5±5.7% of the FF was smaller than 11.2mm and the fraction resembled soil. The total solids (TS) content was 46-82%, being lower in the bottom layers compared to the middle layers. The organic matter content (measured as volatile solids, VS) and the biochemical methane potential (BMP) of FF were lower in the old landfill (VS/TS 12.8±7.1% and BMP 5.8±3.4 m(3)CH4/t TS) than in the new landfill (VS/TS 21.3±4.3% and BMP 14.4±9.9 m(3)CH4/t TS), and both were lower compared with fresh MSW. In the Kuopio landfill materials were also mechanically sieved in the full scale plant in two size fraction <30 mm (VS/TS 31.1% and 32.9 m(3)CH4/t TS) and 30-70 mm (VS/TS 50.8% and BMP 78.5m(3)CH4/t TS). The nitrogen (3.5±2.0 g/kg TS), phosphorus (<1.0-1.5 g/kg TS) and soluble chemical oxygen demand (COD) (2.77±1.77 kg/t TS) contents were low in all samples. Since FF is major fraction of the content of landfill, the characterization of FF is important to find possible methods for using or disposing FF mined from landfills. PMID:25817722

    Only a few countries have introduced health education (HE) as a stand-alone school subject. In Finland every pupil in basic education grades 7-9 takes three obligatory courses in HE. This study investigated Finnish pupils' perceptions of the teaching and learning of HE. It also explored how school- and family-related background variables are associated with these perceptions. Nationally representative data were obtained from a 2010 school-based study on Health Behaviour in School-aged Children (HBSC). A total of 4262 pupils from 7th and 9th grades (13 and 15 years old) responded anonymously to the questionnaire. Logistic regression analysis was performed to identify the associations between perceptions of HE and school- and family-related background variables. The majority of the pupils had positive perceptions of HE. In terms of their own learning, girls' perceptions were more positive than boys': 86% of 13- and 15-year-old girls agreed that HE classes had taught them to think about the advantages and disadvantages of various health behaviours, whereas only 79% of boys shared this opinion. School engagement had the strongest association with perceptions of HE: the more positive the attitudes towards school, the more positive were the perceptions of HE. Older girls perceived their learning and their participation in class discussions more positively than younger ones, and older boys were more critical of the teaching than younger ones. The pupils' educational aspirations were not associated with their perceptions of HE, and perceived family affluence was associated only with girls' perceptions of participation in HE classes. The pupils' feedback on HE was positive and encouraging. There is a demand for the subject in society, and HE seems to have the potential to augment young people's positive attitudes towards health issues, and to enhance their health literacy.

    Highly polymorphic segments of the human genome containing variable numbers of tandem repeats (VNTRs) have been widely used to establish DNA profiles of individuals for use in forensics. Methods of estimating the probability of occurrence of matching DNA profiles between two randomly selected individuals have been subject to extensive debate regarding the possibility of significant substructure occurring within the major races. We have sampled two Caucasian subpopulations, Finns and Italians, at four commonly used VNTR loci to determine the extent to which the subgroups differ from each other and from a mixed Caucasian database. The data were also analyzed for the occurrence of linkage disequilibrium among the loci. The allele frequency distributions of some loci were found to differ significantly among the subpopulations in a manner consistent with population substructure. Major differences were also found in the probability of occurrence of matching DNA profiles between two individuals chosen at random from the same subpopulation. With respect to the Finnish and Italian subpopulations, the conventional product rule for estimating the probability of a multilocus VNTR match using a mixed Caucasian database consistently yields estimates that are artificially small. Systematic errors of this type were not found using the interim ceiling principle recently advocated in the National Research Council's report [National Research Council (1992) DNA Technology in Forensic Science (Natl. Acad. Sci., Washington)]. The interim ceiling principle is based on currently available racial or ethnic databases and sets an arbitrary lower limit on each VNTR allele frequency. In the future the ceiling frequencies are expected to be established from more adequate data acquired for relevant VNTR loci from multiple subpopulations. Images PMID:1438254

    The antimicrobial activity and phenolic compounds of five Finnish honey products against important human pathogens Streptococcus pneumoniae, S. pyogenes, Staphylococcus aureus, and methicillin-resistant S. aureus were analyzed. Microbroth dilution method and HPLC-DAD were used in antimicrobial testing and phenolic compound determination, respectively. Significant antimicrobial activity (p < 0.01) against all the tested pathogens was found from willow herb (Epilobium angustifolium), heather (Calluna vulgaris), and buckwheat (Fagopyrum esculentum) honeys. This is the first report on antimicrobial activity of Finnish monofloral honeys against streptococcal and staphylococcal bacteria. To our knowledge this is also the first report on the antimicrobial effect of honey against S. pneumoniae. PMID:23278378

    Research on the effects of urban sprawl on carbon stocks within urban forests can help support policy for sustainable urban design. This is particularly important given climate change and environmental deterioration as a result of rapid urbanization. The purpose of this study was to quantify the effects of urban sprawl on dynamics of forest carbon stock and density in Xiamen, a typical city experiencing rapid urbanization in China. Forest resource inventory data collected from 32,898 patches in 4 years (1972, 1988, 1996 and 2006), together with remotely sensed data (from 1988, 1996 and 2006), were used to investigate vegetation carbon densities and stocks in Xiamen, China. We classified the forests into four groups: (1) forest patches connected to construction land; (2) forest patches connected to farmland; (3) forest patches connected to both construction land and farmland and (4) close forest patches. Carbon stocks and densities of four different types of forest patches during different urbanization periods in three zones (urban core, suburb and exurb) were compared to assess the impact of human disturbance on forest carbon. In the urban core, the carbon stock and carbon density in all four forest patch types declined over the study period. In the suburbs, different urbanization processes influenced forest carbon density and carbon stock in all four forest patch types. Urban sprawl negatively affected the surrounding forests. In the exurbs, the carbon stock and carbon density in all four forest patch types tended to increase over the study period. The results revealed that human disturbance played the dominant role in influencing the carbon stock and density of forest patches close to the locations of human activities. In forest patches far away from the locations of human activities, natural forest regrowth was the dominant factor affecting carbon stock and density. PMID:23122621

    Random Forest has become a standard data analysis tool in computational biology. However, extensions to existing implementations are often necessary to handle the complexity of biological datasets and their associated research questions. The growing size of these datasets requires high performance implementations. We describe CloudForest, a Random Forest package written in Go, which is particularly well suited for large, heterogeneous, genetic and biomedical datasets. CloudForest includes several extensions, such as dealing with unbalanced classes and missing values. Its flexible design enables users to easily implement additional extensions. CloudForest achieves fast running times by effective use of the CPU cache, optimizing for different classes of features and efficiently multi-threading. https://github.com/ilyalab/CloudForest.

    Only a few empirical studies on forest aesthetics have adopted a water-based perspective for observers and have investigated the perceived visual quality of forested shorelines. In forested environments with many lakes, such as the boreal forest in the Canadian Shield, individuals have greater exposure to forests from water-based rather than in-stand vantage points. This study employed the psychophysical research direction to explore the relationships between scenic beauty and biophysical characteristics of the forested shorelines in the boreal forests. Two model forms were tested. One model related the variation of shoreline forest aesthetic evaluations of near-vista views (140 m offshore) to a set of forest mensuration data. Tree size, tree mortality, conifer shrubs, tree density, amount of hardwood, and slope explained 60.2% of the variance in scenic beauty between the study sites. A second model was calibrated to test the relationship between an already existing ecosystem vegetation classification system and the aesthetic evaluations of the same forested shorelines. When the ecosystem classification was simplified to eight groups, the model explained 48.5% of variance. These models suggest that the psychophysical approach to studying aesthetics can be applied successfully to near-vista evaluations of scenic beauty. The finding that a forest ecosystem classification system is highly related to scenic beauty suggests that, at least in the boreal forest, managers can reasonably estimate the scenic beauty of forested shoreline environments from an ecosystem classification, with little need for intensive data on these sites.

    Spectral patterns of different forest land cover can identify certain pollution compounds, and water stress conditions based on the interaction of photons with the molecular structure of the forest target structure. Based on such methods, the objective of this research was to evaluate and characterize selected forest test area Baneasa- Tunari located in the Northern part of Bucharest metropolitan region, Romania, where the climate and anthropogenic stressors endanger natural and economical values of environment. Based on time-series Landsat TM, ETM, MODIS Terra/Aqua and IKONOS satellite data have been investigated urban forest land cover and forest biophysical parameters (Normalized Difference Vegetation Index- NDVI and Leaf Area Index- LAI) changes over 1990- 2011 period of time. Accuracy of image processing results (spectral classification) was confirmed through in-situ spectroradiometrical analysis of reflectance spectra with portable GER 2600 spectroradiometer.

    Forest pathology, the science of forest health and tree diseases, is operating in a rapidly developing environment. Most importantly, global trade and climate change are increasing the threat to forest ecosystems posed by new diseases. Various studies relevant to forest pathology in a changing world are accumulating, thus making it necessary to provide an update of recent literature. In this contribution, we summarize research at the interface between forest pathology and landscape ecology, biogeography, global change science and research on tree endophytes. Regional outbreaks of tree diseases are requiring interdisciplinary collaboration, e.g. between forest pathologists and landscape ecologists. When tree pathogens are widely distributed, the factors determining their broad-scale distribution can be studied using a biogeographic approach. Global change, the combination of climate and land use change, increased pollution, trade and urbanization, as well as invasive species, will influence the effects of forest disturbances such as wildfires, droughts, storms, diseases and insect outbreaks, thus affecting the health and resilience of forest ecosystems worldwide. Tree endophytes can contribute to biological control of infectious diseases, enhance tolerance to environmental stress or behave as opportunistic weak pathogens potentially competing with more harmful ones. New molecular techniques are available for studying the complete tree endobiome under the influence of global change stressors from the landscape to the intercontinental level. Given that exotic tree diseases have both ecologic and economic consequences, we call for increased interdisciplinary collaboration in the coming decades between forest pathologists and researchers studying endophytes with tree geneticists, evolutionary and landscape ecologists, biogeographers, conservation biologists and global change scientists and outline interdisciplinary research gaps.

    Forest regeneration following disturbance is a key ecological process, influencing forest structure and function, species assemblages, and ecosystem-climate interactions. Climate change may alter forest recovery dynamics or even prevent recovery, triggering feedbacks to the climate system, altering regional biodiversity, and affecting the ecosystem services provided by forests. Multiple lines of evidence - including global-scale patterns in forest recovery dynamics; forest responses to experimental manipulation of CO2 , temperature, and precipitation; forest responses to the climate change that has already occurred; ecological theory; and ecosystem and earth system models - all indicate that the dynamics of forest recovery are sensitive to climate. However, synthetic understanding of how atmospheric CO2 and climate shape trajectories of forest recovery is lacking. Here, we review these separate lines of evidence, which together demonstrate that the dynamics of forest recovery are being impacted by increasing atmospheric CO2 and changing climate. Rates of forest recovery generally increase with CO2 , temperature, and water availability. Drought reduces growth and live biomass in forests of all ages, having a particularly strong effect on seedling recruitment and survival. Responses of individual trees and whole-forest ecosystems to CO2 and climate manipulations often vary by age, implying that forests of different ages will respond differently to climate change. Furthermore, species within a community typically exhibit differential responses to CO2 and climate, and altered community dynamics can have important consequences for ecosystem function. Age- and species-dependent responses provide a mechanism by which climate change may push some forests past critical thresholds such that they fail to recover to their previous state following disturbance. Altered dynamics of forest recovery will result in positive and negative feedbacks to climate change. Future research on this topic and corresponding improvements to earth system models will be a key to understanding the future of forests and their feedbacks to the climate system. PMID:23529980

    As for the renewable sources for energy production, biomass from forests and wood processing industry comes to the second place. The woody biomass accounts for 1.0 Mtoe, that is equivalent with 1.0 Mtoe of oil. Due to current evaluations, the greatest part of woody biomass would be used for briquettes and pallets production. As the biomass from forests is increasingly becoming the interest of national and international market, a detailed research on overall potential of woody supply from Serbian forests is required. Beech forests account for 29.4 % of forest cover of Serbia. They also have the greatest standing volume (42.4 % of the overall standing volume) and the greatest mean annual increment (32.3 %)(Bankovic,et.al.2009). Herewith, the aim of this poster is to determine the long-term biomass production of these forests.For this purpose a management unit called Lomnicka reka has been chosen. As these beech forests have similar structural development, this location is considered representative for whole Serbia. DBH of all trees were measured with clipper and the accuracy of 0.01 mm, and the heights with a Vertex 3 device (with accuracy of 0.1 m). All measurements were performed on the fields each 500 m2 (square meters). The overall quantity of root biomass was calculated using the allometric equations. The poster shows estimated biomass stocks of beech forests located in Rasina area. Dates are evaluated using non-linear regression (Wutzler,T.et.al.2008). Biomass potential of Serbian beech forests will enable the evaluation of long-term potential of energy generation from woody biomass in agreement with principles of sustainable forest management. The biomass from such beech forests can represent an important substitution for energy production from fossil fuels (e.g. oil) and herewith decrease the CO2 emissions.

  10. Revaluing unmanaged forests for climate change mitigation

    2012-01-01

    Background Unmanaged or old-growth forests are of paramount importance for carbon sequestration and thus for the mitigation of climate change among further implications, e.g. biodiversity aspects. Still, the importance of those forests for climate change mitigation compared to managed forests is under controversial debate. We evaluate the adequacy of referring to CO2 flux measurements alone and include external impacts on growth (nitrogen immissions, increasing temperatures, CO2 enrichment, changed precipitation patterns) for an evaluation of central European forests in this context. Results We deduce that the use of CO2 flux measurements alone does not allow conclusions on a superiority of unmanaged to managed forests for mitigation goals. This is based on the critical consideration of uncertainties and the application of system boundaries. Furthermore, the consideration of wood products for material and energetic substitution obviously overrules the mitigation potential of unmanaged forests. Moreover, impacts of nitrogen immissions, CO2 enrichment of the atmosphere, increasing temperatures and changed precipitation patterns obviously lead to a meaningful increase in growth, even in forests of higher age. Conclusions An impact of unmanaged forests on climate change mitigation cannot be valued by CO2 flux measurements alone. Further research is needed on cause and effect relationships between management practices and carbon stocks in different compartments of forest ecosystems in order to account for human-induced changes. Unexpected growth rates in old-growth forests – managed or not – can obviously be related to external impacts and additionally to management impacts. This should lead to the reconsideration of forest management strategies. PMID:23151318

    The levels-of-growing-stock studies in Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), were designed to test the influence of treatment regimes by using a wide range of retained growing stock on the development of forest growth, yield, and stand structure. Results of the Francis installation located in the headwaters of the Willapa River in Pacific County, Washington, are summarized from calibration at age 15 through age 42 (completion of 60 feet of height growth from calibration, and the planned course of the experimental thinnings plus 5 years). In addition to the eight basic treatments and control common to the other eight study installations in the region, five additional treatments were added at Francis; four late first thinnings (at age 25), which matched the level of growing stock of four standard fixed treatments, and an unthinned western hemlock (Tsuga heterophylla (Raf.) Sarg.). Estimated Douglas-fir site index (50-year base) of this plantation is 124, a mid site II.

    The effectiveness of registered application rates of the insecticide metasystox-R applied with Mauget tree injectors (INJECT-A-CIDE) was assessed in two strategies: (1) treatment of trees before western pine beetle attack (preventive treatment), and (2) treatment of trees after attack by western pine beetle (remedial treatment) for protection of individual, high-value ponderosa pine. This field test was conducted on the western slope of the Sierra Nevada on the Eldorado National Forest in central California by using three treatments: metasystox-R injected about 14 days before the onset of beetle attack; metasystox-R injected about 7 days after the onset of beetle attack; and an untreated check.

    Douglas-fir seedlings on the Arcata District, Bureau of Land Management, U.S. Department of the Interior, in central coastal California, were planted in an effort to restore the natural forest to what was then pastureland. Douglas-fir seedlings were released from a complex forb-gass-fern plant community by applying very large (10-ft square) and very small (2-foot square) durable mulches one month after planting. In spite of high cost, the promising role of large mulches for establishing fast-growing Douglas-fir seedlings on a harsh site and the increased stability and sustainability that the future trees will bring to the more natural plant community give large mulches a place in the toolkit of ecosystem managers.

  14. Modeling Forest Structure and Vascular Plant Diversity in Piedmont Forests

    2014-12-01

    When the interacting stressors of climate change and land cover/land use change (LCLUC) overwhelm ecosystem resilience to environmental and climatic variability, forest ecosystems are at increased risk of regime shifts and hyperdynamism in process rates. To meet the growing range of novel biotic and environmental stressors on human-impacted ecosystems, the maintenance of taxonomic diversity and functional redundancy in metacommunities has been proposed as a risk spreading measure ensuring that species critical to landscape ecosystem functioning are available for recruitment as local systems respond to novel conditions. This research is the first in a multi-part study to establish a dynamic, predictive model of the spatio-temporal dynamics of vascular plant diversity in North Carolina Piedmont mixed forests using remotely sensed data inputs. While remote sensing technologies are optimally suited to monitor LCLUC over large areas, direct approaches to the remote measurement of plant diversity remain a challenge. This study tests the efficacy of predicting indices of vascular plant diversity using remotely derived measures of forest structural heterogeneity from aerial LiDAR and high spatial resolution broadband optical imagery in addition to derived topo-environmental variables. Diversity distribution modelling of this sort is predicated upon the idea that environmental filtering of dispersing species help define fine-scale (permeable) environmental envelopes within which biotic structural and compositional factors drive competitive interactions that, in addition to background stochasticity, determine fine-scale alpha diversity. Results reveal that over a range of Piedmont forest communities, increasing structural complexity is positively correlated with measures of plant diversity, though the nature of this relationship varies by environmental conditions and community type. The diversity distribution model is parameterized and cross-validated using three high quality vegetation survey datasets, including Duke Forest Korstian permanent plots, Forest Inventory Analysis (FIA), and the scale transgressive, nested module Carolina Vegetation Survey (CVS).

    As part of research on forest ecosystems, the Jet Propulsion Laboratory (JPL) and collaborating research teams have conducted multi-season airborne synthetic aperture radar (AIRSAR) experiments in three forest ecosystems including temperate pine forest (Duke, Forest, North Carolina), boreal forest (Bonanza Creek Experimental Forest, Alaska), and northern mixed hardwood-conifer forest (Michigan Biological Station, Michigan). The major research goals were to improve understanding of the relationships between radar backscatter and phenological variables (e.g. stand density, tree size, etc.), to improve radar backscatter models of tree canopy properties, and to develop a radar-based scheme for monitoring forest phenological changes. In September 1989, AIRSAR backscatter data were acquired over the Duke Forest. As the aboveground biomass of the loblolly pine forest stands at Duke Forest increased, the SAR backscatter at C-, L-, and P-bands increased and saturated at different biomass levels for the C-band, L-band, and P-band data. We only use the P-band backscatter data and ground measurements here to study the relationships between the backscatter and stand density, the backscatter and mean trunk dbh (diameter at breast height) of trees in the stands, and the backscatter and stand basal area.

    We investigated the external factor (solar activity, volcanic eruptions) influence on tree growth at high latitudes. We analysed a 561-year tree-ring record of pine (Pinus sylvestris L.) and a 676-year juniper (Juniperus Sibirica Burgst.) tree-ring chronology collected nearby the northern timberline (67.77-68.63N; 33.25-36.52 E) at the Kola Peninsula, northwestern Russia. As well known the climatic impacts of solar and volcanic activity vary regionally, and major volcanic eruptions do not always result in regional cooling. A response of tree growth at the Kola Peninsula to climatic changes due to solar variability and volcanic eruptions was revealed. For example, Dalton minimum of solar activity (1801-1816 AD) and Laki (1783 AD) and Tambora (1815 AD) volcanic eruptions appeared to cause the greatest ring-width reduction and cooling. The minima of solar activity Sporer (1416-1534 AD) and Maunder (1645-1715 AD) were as well accompanied by temperature decreases. Intervals with an absence of significant volcanic eruptions correspond to intervals of increased ring-width values. A superposed epoch analysis of 19 large (Volcanic Explosivity Index, VEI>5) volcanic events revealed a significant suppression of tree growth for up to 8 years following volcanic eruptions. The similar effect (supression of tree growth after powerful volcanic eruptions) was obtained under analysis of the 7641-year supra-long pine tree-ring chronology for Finnish Lapland. Our results documenting the regional climatic impacts of solar and volcanic activity permit us to understand the dynamics of the climate system and its response to external forcing.

    There is considerable evidence showing that night work is associated with increased morbidity, but only a few studies have focused on its relation to mortality. This study investigates the relationship between the type of working-time arrangement (weekly night work/daytime work) and total and cause-specific mortality among men and women. The data consist of a representative working conditions survey of Finnish employees conducted in 1984 (2286 men/2216 women), which has been combined with register-based follow-up data from Statistics Finland covering the years 1985-2008. In the 1984 survey, the employees were asked if they worked during the night (23:00-06:00 h) and if so, how often. In this study, the authors compare employees who worked at night (121 men/89 women) to daytime employees who did not do night work (1325 men/1560 women). The relative risk of death was examined by Cox proportional hazards analyses adjusted for background (age, level of education, family situation, and county), health (longstanding illness, pain symptoms, smoking status, and psychological symptoms), and work-related factors (weekly working hours, physical and psychological demands, demands of learning at work, and perceived job insecurity). Female employees working at night had a 2.25-fold higher risk of mortality than female dayworkers (95% confidence interval [CI] 1.20-4.20) after adjustment for background and health- and work-related factors. In addition to total mortality, night work was also associated with tumor mortality. Female night workers had a 2.82-fold higher risk of tumor mortality than female dayworkers (95% CI 1.20-6.65) in the adjusted model. Among men, no such significant association was observed. The present study indicated that female night workers had a higher risk of both total and tumor mortality compared to female daytime employees. Additional research on the potential factors and mechanisms behind the association between night work and mortality is required. PMID:22621357

  18. Risk Behavior for Travelers' Diarrhea Among Finnish Travelers.

    Background: Contaminated food and drink are the primary sources of traveler's diarrhea (TD). Identification of the characteristics that make a traveler more prone to TD is needed to improve prevention and therapy of this illness. Methods: We evaluated, by questionnaire, the association of dietary errors with TD among 933 adult Finnish tourists vacationing in Morocco. A stool specimen was obtained from patients in the group that developed TD at the onset of the diarrheal episode, and from all participants in the study on their return to Finland. Results: Only 5% of the 933 subjects who responded to the questionnaire, and who gave a stool sample, had adhered strictly to generally accepted recommendations. About 45% made five or more dietary errors during the trip; of these, 75% consumed raw vegetables, 65% salads, 33% puddings, 32% mayonnaise or other cold dressings, 31% consumed food bought from street vendors, 29% consumed cold meat, 18% cold sandwiches, 4% drank tap water, and 2% consumed raw meat. The age of the subjects did not correlate with the number of dietary errors. Subjects who had been abroad during the preceding 12 months committed more dietary errors than those who had not (mean 3.9 versus 4.5; p <.001). Also, subjects who spent 2 weeks in Morocco committed more dietary errors than those who spent only 1 week (mean 4.0 versus 4.8; p <.001). However, no association between TD and the number of dietary errors was observed. Differences with respect to eating habits were not observed between subjects, with or without TD or with or without an identified pathogen in stool specimens. There was no correlation between eating habits and the presence, or absence, of a specific pathogen in the stool sample; this is with the exception of Campylobacter spp: subjects with this pathogen consumed steak tartar or salad more often than did other subjects. Conclusions: Etiologic agents are so ubiquitous in this high-risk area that instructions to avoid certain foodstuffs commonly thought to be contaminated may be to some extent without value. Moreover, dietary self restraint proved to be impossible in the real situation. (J Travel Med 2:77-84, 1995) PMID:9815366

  19. Black carbon concentrations and mixing state in the Finnish Arctic

    Atmospheric aerosol composition was measured using a Single Particle Soot Photometer (SP2) in the Finnish Arctic during winter 2011-2012. The Sammaltunturi measurement site at the Pallas GAW (Global Atmosphere Watch) station receives air masses from different source regions including the Arctic Ocean and continental Europe. The SP2 provides detailed information about mass distributions and mixing state of refractory black carbon (rBC). The measurements showed widely varying rBC mass concentrations (0-120 ng m-3), which were related to varying contributions of different source regions and aerosol removal processes. The rBC mass was log-normally distributed showing a relatively constant rBC core mass mean diameter with an average of 194 nm (75-655 nm sizing range). On average, the number fraction of particles containing rBC was 0.24 (integrated over 350-450 nm particle diameter range) and the average particle diameter to rBC core volume equivalent diameter ratio was 2.0 (averaged over particles with 150-200 nm rBC core volume equivalent diameters). These average numbers mean that the observed rBC core mass mean diameter is similar to those of aged particles, but the observed particles seem to have unusually high particle to rBC core diameter ratios. Comparison of the measured rBC mass concentration with that of the optically detected equivalent black carbon (eBC) using an Aethalometer and a MAAP showed that eBC was larger by a factor of five. The difference could not be fully explained without assuming that only a part of the optically detected light absorbing material is refractory and absorbs light at the wavelength used by the SP2. Finally, climate implications of five different black carbon mixing state representations were compared using the Mie approximation and simple direct radiative forcing efficiency calculations. These calculations showed that the observed mixing state means significantly lower warming effect or even a net cooling effect when compared with that of a homogenous aerosol containing the same amounts of black carbon and non-absorbing material.
