The Significance of Forest Monitoring Programmes: the Finnish Perspective  

NASA Astrophysics Data System (ADS)

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.

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

PubMed

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.

Forest medicine research in Japan.  

PubMed

There has been growing attention on the effects of forest on physiological relaxation and immune recovery, particularly in forest medicine research, from a perspective of preventive medicine. Japan is a world leader in the accumulation of scientific data on forest medicine research. In this review, we summarize the research that has been conducted in this area since 1992. We conducted field experiment, involving 420 subjects at 35 different forests throughout Japan. After sitting in natural surroundings, these subjects showed decrease in the following physiological parameters compared with those in an urban control group: 12.4% decrease in the cortisol level, 7.0% decrease in sympathetic nervous activity, 1.4% decrease in systolic blood pressure, and 5.8% decrease in heart rate. This demonstrates that stressful states can be relieved by forest therapy. In addition, it should be noted that parasympathetic nervous activity was enhanced by 55.0%, indicating a relaxed state. The results of walking experiments provided similar results. Li et al. demonstrated that immune function was enhanced by forest therapy in middle-aged employees who volunteered to participate in these experiments. Natural killer cell activity, an indicator of immune function, was enhanced by 56% on the second day and returned to normal levels. A significant increase of 23% was maintained for 1 month even after returning to urban life, clearly illustrating the preventive benefits of forest therapy. In an indoor room experiment, we conducted tests with the following: 1) olfactory stimulation using wood smell, 2) tactile stimulation using wood, and 3) auditory stimulation using forest sounds. These indoor stimulations also decreased the blood pressure and pulse rate, and induced a physiological relaxation effect. We anticipate that forest medicine will play an increasingly important role in preventive medicine in the future. PMID:24858508

Parallel estimates of gross primary production of Finnish forests - comparison of two process models  

NASA Astrophysics Data System (ADS)

Land Surface Models (LSM) describe the material and energy fluxes between the atmosphere, vegetation and soils for climate models and earth system models. Especially, for past and future climate change studies, LSMs need to include ecosystem carbon cycle. Process-based forest growth models and ecosystem impact analysis models, on the other hand, benefit from stand-alone predictions of carbon cycle. In this study, we compared the predictions of GPP made with two modelling systems that are currently applied in Finland. The first one is JSBACH that is LSM of ECHAM6, which is now being applied in Finland with the REMO regional climate model. The second one is the eddy-flux-based GPP and water balance model PRELES that has recently been integrated with large-scale data sets to be run with inventory-based forest data and ground-based meteorological measurements. JSBACH was run with information about plant functional type fractions in 0.167 degree pixels. PRELES applied inventory-scaled information about forest structure on fine resolution (100 m). Both models used same weather data as inputs. When we compared the results of the two model systems, we found little difference between the model predicted annual GPP when aggregated over Finland. Spatial differences in annual GPP and its inter-annual variation over the simulation period (2000-2011) was also parallel, but differences were detected in the seasonal pattern of GPP. Two modelling system showed remarkable converge in predicted annual total GPP, but both models could benefit from a better understanding of timing of the season start and end, especially regarding deciduous species.

Long-term changes in acidity and DOC in throughfall and soil water in Finnish forests.  

PubMed

The main objective of this study was to examine if any detectable trends in dissolved organic carbon (DOC), sulphate (SO4-S) concentrations and acid neutralizing capacity (ANC) in throughfall (TF) and soil water (SW) could be found during 1990-2010 and to relate them to recent changes in decreased acid deposition. The study was conducted in seven boreal coniferous forest sites: four of which are managed and three unmanaged forests sites. Generally, temporal trend showed a significant decrease in SO4-S concentrations in bulk precipitation (BP), TF and SW. At some of the sites, there was an increasing tendency in BP and TF in the DOC concentrations. This feature coincides with decreasing SO4-S concentration, indicating that SO4-S may be an important driver of DOC release from the canopy. However, a slightly increased temperature, larger senescing needle mass and consequently increased decaying activity in the canopy may partly explain the increasing trend in DOC. In SW, no consistent DOC trend was seen. At some sites, the decreased base cation concentrations mostly account for the decrease in the ANC values in SW and TF. PMID:25096641

VOCs measurement at Tomakomai research forest, Japan  

NASA Astrophysics Data System (ADS)

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.

Long-Term Research at the USDA Forest Service's Experimental Forests and Ranges  

NSDL National Science Digital Library

This peer reviewed article from BioScience is on USDA Forest Service's long-term databases. The network of experimental forests and ranges administered by the US Department of Agriculture Forest Service consists of 77 properties that are representative of most forest cover types and many ecological regions in the nation. Established as early as 1908, these sites maintain exceptional, long-term databases on environmental dynamics and biotic responses. Early research at these sites focused on silviculture, ecosystem restoration, and watershed management. Over time, many of the properties have evolved into a functional network of ecological observatories through common large-scale, long-term experiments and other approaches. Collaboration with other institutions and research programs fosters intersite research and common procedures for managing and sharing data. Much current research in this network focuses on global change and interdisciplinary ecosystem studies at local to global scales. With this experience in developing networks and compiling records of environmental history, the experimental forests and ranges network can contribute greatly to formation of new networks of environmental observatories.

Towards an international electronic repository and virtual laboratory of open data and open-source software for telehealth research: comparison of international, Australian and Finnish privacy policies.  

PubMed

Health data includes all content related to health in all data formats, document types, information systems, publication media and languages from all specialties, organisations, regions, states and countries. Capabilities to share, integrate and compare these data contents, clinical trial results and other evaluation outcomes together with telehealth applications for data processing are critical to accelerate discovery and its diffusion to clinical practice. However, the same ethical and legal frameworks that protect privacy hinder this open data and open-source code approach and the issues accumulate if moving data across national, regional or organisational borders. This can be seen as one of the reasons why many telehealth applications and health-research findings tend to be limited to very narrow domains and global results are lacking. The aim of this paper is to take steps towards establishing an international electronic repository and virtual laboratory of open data and open-source code for research purposes by comparing international, Australian and Finnish frameworks. The frameworks seem to be fundamentally similar; they apply the principles of accountability and adequacy to using and disclosing personal data. Their requirements to inform data subjects about the purposes of data collection and use before the dataset is collected, assure that individuals are no longer identifiable and to destruct data when the research activities are finished make sharing data and even secondary data difficult. Using the Internet or cloud services for sharing without proper approvals by ethics committees is technically not allowed if the data are stored in another country. The research community needs to overcome these barriers and develop a virtual laboratory, which operates on distributed data repositories. This empowers the community by enabling systematic evaluations of new technologies and research hypotheses on a rich variety of data and against existing applications, and subsequent tracking of quality improvements in time.

Size and composition measurements of background aerosol and new particle growth in a Finnish forest during QUEST 2 using an Aerodyne Aerosol Mass Spectrometer  

NASA Astrophysics Data System (ADS)

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. Hyytil, 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.

Finnish care integrated?  

PubMed Central

Abstract 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

Finnish students' perceptions of a visiting professor.  

PubMed

Although nurse educators enthusiastically endorse visiting professors, cross-school collaboration, cross-cultural teaching, and international faculty exchange programs, no previous studies have documented students' perceptions of visiting faculty. An open-ended questionnaire was used to identify Finnish students' perceptions of a visiting Fulbright professor and how faculty and students can better prepare for educational exchanges. Four themes emerged from the content analysis of responses to the questionnaire: course content, teaching methods, the role of the teacher, and expectations and developmental challenges. Generally, students were satisfied with the course content and teaching methods. They indicated that it was important that the teacher was encouraging and positive and challenged them to speak up in class. Students commented that the visiting professor should perhaps have been more knowledgeable about and therefore able to make applications to Finnish culture, education, and the health care system. Others noted that it was helpful to learn about the American health care system and then to make applications to Finnish culture themselves. Overall, the findings of this project support continuation of visiting professors and continued research on methods of increasing visiting faculty program effectiveness. PMID:12748935

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.

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.

On the early history of the Finnish Meteorological Institute  

NASA Astrophysics Data System (ADS)

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 Sodankyl, Lapland.

Avian research on U.S. Forest Service Experimental Forests and Ranges: Emergent themes, opportunities, and challenges  

USGS Publications Warehouse

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.

Forest pathology research in the Nordic and Baltic countries 2005 Proceedings from the SNS meeting in Forest Pathology  

E-print Network

In 1972 a Nordic Cooperative Group on Forest Pathology was established on a request from the recently established Nordic Forestry Research Cooperation Committee (SNS) under the Council of Nordic Ministers (NMR). Since then a meeting for Nordic forest pathologists has been held every second year, the organising circulating between the Nordic countries. During the 1990s the Baltic countries were invited to participate, and in 2000 the first SNS-meeting for forest pathologists was held in a Baltic country, Estonia. The present meeting was organized by Halvor Solheim with help from Isabella Brja and Knut J. Huse. Halvor Solheim was also responsible for the excursion, which included a visit to forests near the timber line, and hiking up to the mountain Ormtjernkampen in the recently established Ormtjernkampen National Park. In autumn 1938 a forest officer was in the area mar-king timber, and he realized there were no old stumps indicating human activity, which resulted in a process to prevent the forest. The area was protected in 1956, and in 1968 it was assigned the status of national park. The name Ormtjernkampen comes from three words: orm ( = worm), tjern ( = a small lake), and kampen (one of many different Norwegian words for a mountain).

An imperative need for global change research in tropical forests.  

PubMed

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.

Managing coarse woody debris in forests of the Rocky Mountains. Forest Service research paper  

SciTech Connect

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.

[Research advances in dynamic mechanism and its simulation of eco-hydrological process in forest catchment].  

PubMed

Hydrological process is the key link between climatic fluctuations and ecologic dynamics of forests at spatial and temporal scales. To some extent, global climate change and large-scale human's activities will impact the spatial-temporal changes of eco-hydrological process in forest catchments in the future. Therefore, researches on the dynamic mechanism of eco-hydrological processes in forest catchments play a crucial role in understanding and controlling the rational use of ecological resources, resuming regional ecology, and sustainable development in economy. This paper described the interception, evapotranspiration and rainfall-runoff of forest ecological system and their effects on hydrological process. The spatial structure of soil moisture and its evolution with time were also the cause and consequence of forest. The spatial-temporal interaction between hydrologic and ecologic dynamics, the application of distributed hydrological model, and the eco-hydrological dynamics and cybernetics of forest would be the most exciting frontiers of the relative researches in the future.

Tropical forest responses to increasing [CO2]: current knowledge and opportunities for future research  

SciTech Connect

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.

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.

Forest management under changing climate conditions: Is timing a tool for Sustainable Forest Management? Relevant questions for research development  

NASA Astrophysics Data System (ADS)

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.

The authors examine goodness of fit of two predictor variables (shrub height and stem diameter class) in three relations. The authors provide equations that use stem diameter class or stem diameter class and height to estimate biomass of six components of five shrub species, as well as generalized equations derived from a composite of all five species. Finally, the authors provide the information needed to construct standard errors for biomass estimates.

Studies of space weather effects on the finnish natural gas pipeline and on the finnish high-voltage power system  

NASA Astrophysics Data System (ADS)

Geomagnetically induced currents (GIC) in technological systems are the ground end of the complicated space weather chain. GIC are a possible source of problems to the systems. In power networks, GIC cause saturation of transformers, which may even result in a collapse of the whole system and in damage of transformers. Pipelines can suffer from problems associated with corrosion and its control. The Finnish high-voltage power grid and the Finnish natural gas pipeline have not encountered GIC harm but due to the high-latitude location of the country and to a general interest in phenomena in the auroral region, an active research of the occurrence of GIC in these systems has been continued for about twenty years. The studies carried out have contained both GIC measurements and theoretical modelling, partly based on geomagnetic data. Estimates of expectable GIC magnitudes at different sites of the systems have been derived. However, GIC values greatly depend on the network configuration, so GIC estimates need not be valid after changes in the configuration. The electric field at the Earth's surface is the key parameter when calculating GIC in a network as it is not affected by network configuration changes. Future efforts in investigations of GIC will be focused on understanding ionospheric and magnetospheric processes responsible for large GIC events.

Three decades of research at Flakaliden advancing whole-tree physiology, forest ecosystem and global change research.  

PubMed

Nutrient supply often limits growth in forest ecosystems and may limit the response of growth to an increase in other resources, or to more favorable environmental factors such as temperature and soil water. To explore the consequences and mechanisms of optimum nutrient supply for forest growth, the Flakaliden research site was established in 1986 on a young Norway spruce site with nutrient-poor soil. This special section on research at Flakaliden presents five papers that explore different facets of nutrition, atmospheric CO2 concentration, [CO2], and increased temperature treatments, using the original experiment as a base. Research at Flakaliden shows the dominant role of nutrition in controlling the response of growth to the increased photosynthesis promoted by elevated [CO2] and temperature. Experiments with whole-tree chambers showed that all treatments (air temperature warming, elevated [CO2] and optimum nutrition) increased shoot photosynthesis by 30-50%, but growth only increased with [CO2] when combined with the optimum nutrition treatment. Elevated [CO2] and temperature increased shoot photosynthesis by increasing the slope between light-saturated photosynthesis and foliar nitrogen by 122%, the initial slope of the light response curve by 52% and apparent quantum yield by 10%. Optimum nutrition also decreased photosynthetic capacity by 17%, but increased it by 62% in elevated [CO2], as estimated from wood ?(13)C. Elevated air temperature advanced spring recovery of photosynthesis by 37%, but spring frost events remained the controlling factor for photosynthetic recovery, and elevated [CO2] did not affect this. Increased nutrient availability increased wood growth primarily through a 50% increase in tracheid formation, mostly during the peak growth season. Other notable contributions of research at Flakaliden include exploring the role of optimal nutrition in large-scale field trials with foliar analysis, using an ecosystem approach for multifactor experiments, development of whole-tree chambers allowing inexpensive environmental manipulations, long-term deployment of shoot chambers for continuous measurements of gas exchange and exploring the ecosystem response to soil and aboveground tree warming. The enduring legacy of Flakaliden will be the rich data set of long-term, multifactor experiments that has been and will continue to be used in many modeling and cross-site comparison studies.

NSF Research Experience for Undergraduates: 3-D Characterization and Comparison of Vegetation Structure in a Tropical Premontane Wet Forest  

NASA Astrophysics Data System (ADS)

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.

An Undergraduate Research Experience: Wireless Propagation and Position Location in a Forest Environment  

NSDL National Science Digital Library

Over the past several years, the undergraduate curriculum at many universities has been evolving to incorporate laboratory exercises and research projects to reinforce and support traditional classroom lectures. In particular, involving undergraduates in meaningful research projects is a key to providing them with the hands-on activities students are demanding. Unfortunately, two areas in the electrical engineering curriculum are suffering from a lack of meaningful hands-on learning activities: electromagnetics and communications. At many universities, electromagnetics is taught as a highly theoretical, highly mathematical class with the goal of providing students a deep understanding of Maxwells equations. Students that complete such a course generally struggle when faced with applying Maxwells equations to real-world electromagnetics problems such as transmission lines, antenna design, or wireless propagation. Introductory communications courses may have laboratory components, however, involving students in an undergraduate research project is an excellent mechanism to supplement and reinforce the laboratory exercises. This paper presents a summer undergraduate research experience that involved characterizing ultra wideband wireless propagation and position location in a forest environment. Four undergraduate students were selected to participate in the research experience. All four students had taken the basic electromagnetics and communications courses, although only one had prior hands-on experience. Additionally, the use of impulse ultra-wideband signals represented a new wireless communication scheme that students had to master at the beginning of the research experience. After an initial training period, students were tasked with site selection, experimental design, recording measurements, analyzing data, and troubleshooting equipment failures. Although it is too early to assess the impact of the research experience on these students careers, the experience appears to have been a success. All four students reported a greater depth of understanding of the concepts taught in electromagnetics and communications courses. Additionally, students gained valuable experience in developing and carrying out field experiments sometimes in less than ideal conditions and as a result of this experience, some students expressed a desire to pursue a graduate degree. Designing this research project also provided several valuable lessons to the instructors which will aid in the further development of hands-on learning activities for electromagnetics and communications courses.

Boreal Forest Fire Biomass Consumption for Carbon Emission Estimation: Measurement Requirements and Current Research  

NASA Astrophysics Data System (ADS)

Quantification of carbon emissions from boreal fire includes measuring both spatial extent and biomass consumed during the fire and converted to atmospheric carbon. Based on previous research, it is hypothesized that the variability in biomass consumed during fire is the main driver of uncertainty in carbon emission from wildfires. In boreal systems, consumption of both aboveground biomass and carbon held in the forest floor and upper soil layers needs to be assessed. Current emissions models use consumption values based on a few direct measurements and some modeled estimates. For the North American boreal region these values are in the range of 20-25% of aboveground biomass consumed while values range from 5-40% of ground-layer carbon consumed. While these values have been used by many researchers to make emissions estimates, they have not been scrutinized, and the variability in consumption has not been fully assessed. Better measures are needed to define both the typical levels of consumption and describe the variability in consumption possible as a function of vegetation type, biomass density, ground-layer carbon depth, and burn severity. Approaches to quantifying biomass consumption and results of measurement activities are presented in this paper. Direct, field-based measures, requiring measurement from before and after burning, are collected on a limited level. Post-fire field studies, measuring ground-layer depth within and outside of recent burn sites and determining burn depth from analysis of remaining material, have shown a high level of variability in ground-layer burning. Indirect measures include remote sensing; a technique developed to assess ecological burn severity using field data (Composite Burn Index) and pre- and post-fire Landsat images (Normalized Burn Ratio) is being assessed. The Canadian forest fire behavior prediction (FBP) system was developed to predict fire behavior at the fireline. Recently it has been used to estimate the amount of carbon released from fires. This application, while promising, is being validated to confirm whether the FBP consumption levels are correct for carbon emissions estimates. In this paper, we present the work of several groups finding ways to better quantify biomass consumption in boreal fires. We review issues in terminology used by scientists and managers as well as problems of using measurements developed for fire management or ecological studies for the study of carbon emissions. We review how various measurement methods may or may not be useful in estimating biomass consumption and carbon emissions from boreal wildfire.

New international long-term ecological research on air pollution effects on the Carpathian Mountain forests, Central Europe.  

PubMed

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

We present a summary of the trajectory reconstruction, dark flight simulations and pre-impact orbit for a bright fireball that appeared in the night sky over the Kola Peninsula, close to the Finnish border, on April 18 2014, at 22h14m13.0s (UTC). The fireball was instrumentally recorded in Finland from Kuusamo, Mikkeli and Muhos observing sites belonging to the Finnish Fireball Network. Additionally, a publicly available video made by Alexandr Nesterov in Snezhnogorsk (Russia), from the opposite side of the fireball track, was carefully calibrated and taken into account in the trajectory reconstruction. Based on a thorough analysis of the fireball, it was concluded that part of the meteoroid survived atmospheric entry and reached the ground. To further specify an impact area for a dedicated expedition, dark flight simulations were done to build a strewn field map showing the most probable distribution of fragments. A 5-day expedition with 4 participants from Russia and Finland took place at the end of May following snow melt and preceding vegetation growth. On May 29, 2014, a first 120.35 g meteorite fragment was found on a local forest road within the predicted impact area. A second 47.54 g meteorite fragment, fully covered with a fusion crust, was recovered nearby on the following day. Both pieces were preserved in very good condition without apparent weathering.

Research about the location technologies of forest fire detecting based on GIS  

NASA Astrophysics Data System (ADS)

Forest fire caused damages of property and loss of human life. Detecting a forest fire and get the location is very significant in the fire early warning. More early and more prompt detecting fire and determining fire position as far as possible could avoid and reduce loss of the disaster. At present there are three ways regarding the forest fire early warning and location determining which included: monitoring form Remote Sense Satellite image, manual observation and patrols, and automatic monitoring through CCD camera long-distance video. Overall evaluation regarding the three location technologies in forest fire early warning, the CCD camera detecting method is suitable in the fire rapid Response. An automatic forest fire surveillance system was running to detect the fire by using visible light images from the remote cameras. If a forest fire was detected, an alarm will be activated. The observation point elevation values, vertical offsets, horizontal and vertical scanning angles, and scanning distances will be also be sent to the central control room. The spatial orientation will be computed and showed on the electronic map. Key location technologies based on CCD camera included the image processing technique for automatically detecting forest fire and the visibility analyzes technique for the digital elevation model. Jing gang Mountain which locates in Jiangxi province of China is taken as an example. With the help of this automatic monitoring through CCD camera long-distance video and visibility analyzes, scientists and government administrators can make decision-supporting easily when they know exactly where a forest fire is. At last the shortage of CCD camera detecting method was discussed. We cannot depend on CCD camera detecting equipment and technologies only. With foundation of the automatic video frequency supervisory system, we should also strengthen manual observation and satellite remote sensing monitor.

Pathogenic bacteria in Finnish bulk tank milk.  

PubMed

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

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

SciTech Connect

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 at

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.

TAPIR--Finnish national geochemical baseline database.  

PubMed

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 effectiveness of the Finnish EIA system - What works, what doesn't, and what could be improved?  

SciTech Connect

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.

The role of the New Zealand forest industry injury surveillance system in a strategic ergonomics, safety and health research programme.  

PubMed

Forestry is among the most hazardous of all industry sectors internationally. In New Zealand, highest work-related morbidity and mortality incidence rates are found in the logging sector. The New Zealand Forest Industry Accident Reporting Scheme (ARS) is a forestry injury surveillance system maintained by the Centre for Human Factors and Ergonomics (COHFE). The paper highlights the pivotal role of an industry-wide injury surveillance system in an industry-specific strategic research programme, giving examples of the use of ARS data in identification of priority areas for ergonomics, safety and health research attention, for safety awareness feedback to the industry, and in the evaluation of injury countermeasures. An analysis of injury patterns and trends for one high-risk forestry operation (skid work) is presented to illustrate both the capabilities and limitations of the ARS in its present stage of development.

Distribution and Medical Impact of Loss-of-Function Variants in the Finnish Founder Population  

PubMed Central

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 (0.55%) 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<510?8) including splice variants in LPA that lowered plasma lipoprotein(a) levels (P?=?1.510?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?=?310?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.

A national collaboration process: Finnish engineering education for the benefit of people and environment.  

PubMed

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

Grazing on regeneration sites encourages pine seedling growth. Forest Service research paper (Final)  

SciTech Connect

Effects of season-long, deferred-rotation, and rest-rotation grazing, on ponderosa pine (Pinus ponderosa Dougl. ex Laws.) seedling growth and herbaceous vegetation control were studied in regeneration sites at Boyd Hill, Modoc National Forest, California. Seedlings were planted in 1989. Pine seedling survival and damage did not differ, but the seedlings were significantly taller, with longer leaders with season-long grazing than without grazing. Treatment comparisons for plant group and non-plant percent cover differed only for litter and bare soil, but cover and composition of bottlebrush squirreltail (Elymus elymoides (Raf.) Swezey) were greater without grazing.

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

SciTech Connect

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.

Managing lodgepole pine to yield merchantable thinning products and attain sawtimber rotations. Forest Service research paper  

SciTech Connect

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.

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

NASA Astrophysics Data System (ADS)

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 Sirrajrvi, Northern Finnish Lapland in March 2012. Lake Sirrajvri (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 ?18O 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 Sirrajvri ice cover and diatom population dynamics (ongoing since March 2011) further informs palaeoenvironmental interpretation. The resulting high-resolution, multiproxy (diatom, ?18Odiatom, ?13Corganic, 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.

Modeling the population dynamics of pacific yew. Forest Service research note  

SciTech Connect

A study of Pacific yew (Taxus brevifolia Nutt.) population dynamics in the mountains of western Oregon and Washington was based on a combination of long-term population data and computer modeling. Rates of growth and mortality were low in mature and old-growth forest stands. Diameter growth at breast height ranged from 0 to 3 centimeters per decade. The annual mortality rate for individuals greater than 5 centimeters in diameter at breast height was about 1 percent of the population. A matrix population model was constructed by using these and other fundamental data on yew population dynamics. The model was designed to perform population viability analyses of yew under various harvest regimes. Model projections suggested a slow rate of recovery from major disturbance.

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

NASA Astrophysics Data System (ADS)

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.

Teachers' experiences of English-language-taught degree programs within health care sector of Finnish polytechnics.  

PubMed

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

Research observation: Hydrolyzable and condensed tannins in plants of northwest Spain forests  

USGS Publications Warehouse

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.

Biological utilization of wood for production of chemicals and foodstuffs. Forest service research paper  

SciTech Connect

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.

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.

We have screened for germline TP53 mutations in Finnish BRCA1 and BRCA2 mutation-negative families. This study represents the largest survey of the entire protein-encoding portion of TP53, and indicates that mutations are only found at conserved domains in breast cancer families also meeting the criteria for Li-Fraumeni/Li-Fraumeni-like syndrome, explaining only a very small additional fraction of the hereditary breast cancer cases. 2001 Cancer Research Campaign http://www.bjcancer.com PMID:11139324

Translating and validating the Finnish version of the Manchester Clinical Supervision Scale.  

PubMed

Evaluation research provides new perspectives for clinical supervision (CS), and international collaboration offers advantages to develop valid instruments for this purpose. Besides translation, an instrument developed and tested in another culture requires systematic validation. The study focuses on the translation process of the Manchester Clinical Supervision Scale for testing in Finland carried out collaboratively between the Universities of Tampere and Manchester. The instrument is a 45-item questionnaire with a Likert-type (1-5) scale comprising seven sub-scales: trust and rapport, supervisor advice and support, improved care and skills, importance and value of CS, finding time, personal issues and reflection and total score. At first, a licensed translator translated the instrument into Finnish. A native British language teacher at the University language centre performed the blind back-translation into English. The translations were compared by both collaborative parties and by three experienced Finnish supervisors. A pilot sample (n = 182) was collected to test the translated instrument. In this sample Cronbach's alpha value for the total score was 0.9227 and in the sub-scales 0.6393-0.8838. The mean values in the sub-scales were 14.2-29.3, SDs 3.02-3.88 and modes 14.0-30.0. The British test sample had almost similar values. Translating an instrument into another language not only requires expertise in language, but also in practice. The cultural validation is the most important phase in the process that can be accomplished with pilot testing and statistical methods. However, further expert evaluation is required for the validity of the instrument. PMID:14629638

Maternal Serum Persistent Organic Pollutants in the Finnish Prenatal Study of Autism: A Pilot Study  

PubMed Central

Recent research emphasizes the contribution of environmental as well as genetic factors to the etiology of autism but studies testing associations between chemical exposures and autism have been limited. Prenatal exposure to persistent organic pollutants (POPs) has previously been associated with decrements in cognitive and developmental performance. We conducted a pilot study in the Finnish Prenatal Study of Autism (FiPS-A). Seventy-five cases with autism and 75 controls matched on sex, birth year, urbanization and maternal age were sampled from first-born children in the Finnish Maternity Cohort, which includes over 1 million births. The study sample included births occurring from 1991 to 2000. Subjects were followed up for autism through 2007. DDT, DDE, PCB-118, PCB-138, PCB-153, PCB-156, PCB-170, PCB-180, hexachlorobenzene, and BDE-47 were measured in archived maternal serum samples taken during pregnancy using gas chromatography-high resolution mass spectrometry. Correlations between pollutant measures were assessed and mechanistically-related weighting schemes for summarizing PCB levels were compared. Case and control differences were assessed using graphical and statistical methods. All analytes, with the exception of DDT and BDE-47, were detected above the limit of quantification in all samples. The correlation between levels of individual PCB congeners and weighted summary measures was high (0.71-1.00). Paired t-tests revealed no significant differences between cases and controls for log-transformed mean values of any analyte; however, in an adjusted model the odds ratio for autism was 1.91 (p=0.29) and 1.79 (p= 0.36) respectively, for subjects with total PCBs and DDE above the 90th percentile of control values. Levels of prenatal PCB exposure in FIPS-A were similar to levels previously correlated with poorer neurodevelopmental measures in other populations. Further study in a larger sample will be required to fully determine whether exposure to high POP levels are associated with autism diagnosis in the population. PMID:23591055

Anabolic-androgenic steroid use among young Finnish males.  

PubMed

The aim of the present study was to describe the lifetime occurrence and associated factors of anabolic-androgenic steroids (AAS) among young Finnish males. Of the 10 829 male conscripts (median age 19), 10 396 (96%) answered a questionnaire during the first days of their conscription in the years 2001-2007. The main outcome was lifetime AAS use. We also studied associations between 13 socioeconomic, health, and health behavioral background variables and AAS use by logistic regression. Eighty-nine (0.9%) respondents reported having used AAS. In addition, 26 (0.3%) respondents reported that they would use AAS if they could obtain them. In multivariate analysis, which included all significant variables and age, the strongest associated factors were weight training at fitness centers more than three times a week [odds ratio (OR) 11.8; 95% confidence interval (CI): 7.1-19.6], low educational status (OR 3.7; 95% CI: 2.0-7.0), and weekly drunkenness as drinking style (OR 2.4; 95% CI: 1.4-4.5). Sports other than weight training were not associated with AAS in our sample. The use of AAS is relatively uncommon among Finnish males. It is strongly associated with weight training at fitness centers but also with lower educational status and a drunkenness-oriented lifestyle. Prevention should be targeted at those males participating in weight training. PMID:19538536

Ernst Mach and the Epistemological Ideas Specific for Finnish Science Education  

NASA Astrophysics Data System (ADS)

Where does Finnish science education come from? Where will it go? The following outside view reflects on relations, which Finns consider "normal" (and thus unrecognizable in introspection) in science education. But what is "normal" in Finnish culture cannot be considered "normal" for science education in other cultures, for example in Germany. The following article will trace the central ideas, which had a larger influence in the development of this difference. The question is, if and why the Finnish uniqueness in the philosophy of science education is empirically important. This puts Finnish science education into the perspective of a more general epistemological debate around Ernst Mach's Erkenntnistheorie (a German term similar to the meaning of history and philosophy of science, though more general; literally translated "cognition/knowledge theory"). From this perspective, an outlook will be given on open questions within the epistemology of Finnish science education. Following such questions could lead to the adaptation of the "successful" ideas in Finnish science education (indicated by empirical studies, such as the OECD PISA study) as well as the further development of the central ideas of Finnish science education.

Carbon Dioxide Effects Research and Assessment Program. The role of tropical forests on the world carbon cycle  

SciTech Connect

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.

Forest pathology in Hawaii  

USGS Publications Warehouse

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.

International outreach for promoting open geoscience content in Finnish university libraries - libraries as the advocates of citizen science awareness on emerging open geospatial data repositories in Finnish society  

NASA Astrophysics Data System (ADS)

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.

Subjective well-being in Finnish adolescents experiencing family violence.  

PubMed

This article describes the relationship between adolescent subjective well-being and experiences of family violence reported by a sample of 14- to 17-year-old adolescents living in one Finnish municipality (N = 1,393). Survey results found that experiences of family violence were common. The logistic regression model showed that experiences of violence were associated with adolescents' feeling of inner disequilibrium and markedly strong relationships with friends. In additional, adolescents who experienced family violence rated their health as poorer than adolescents from nonviolent homes. They also surprisingly reported being satisfied with their life and did not necessarily identify their need for help. Although adolescents are resilient and have some resources to cope with violence, nurses and other professionals should attend more carefully to adolescents' reports of health and behavioral problems and assess for the presence of family violence and school bullying.

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

PubMed Central

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 (13 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

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

NASA Astrophysics Data System (ADS)

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 (Cerd, 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 (Cerd 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 Cerd 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.

Forest Ecology  

NSDL National Science Digital Library

This tutorial discusses the concept of forest succession, the stages of development which forest plants follow as they grow or re-grow following an event such as a forest fire or insect infestation. Topics include the role of pioneer species, the transition to longer-lived plants such as lodgepole pine, Douglas fir, and subalpine fir, and the transition to climax species such as cedars, hemlocks and spruce. There is also a discussion of the lifespan of climax forests and the wildlife species that inhabit the forest in each stage of succession. A quiz and glossary are provided.

Forest commons and local enforcement  

PubMed Central

This article examines the relationship between local enforcement and forests used as commons. It uses a unique multicountry dataset, created over the past 15 years by the International Forestry Resources and Institutions Research Program. Drawing on original enforcement and forest commons data from 9 countries, we find that higher levels of local enforcement have a strong and positive but complex relationship to the probability of forest regeneration. This relationship holds even when the influence of a number of other factors such as user group size, subsistence, and commercial importance of forests, size of forest, and collective action for forest improvement activities is taken into account. Although several of the above factors have a statistically significant relationship to changes in the condition of forest commons, differences in levels of local enforcement strongly moderate their link with forest commons outcomes. The research, using data from diverse political, social, and ecological contexts, shows both the importance of enforcement to forest commons and some of the limits of forest governance through commons arrangements.

Instar development of the douglas-fir tussock moth in relation to field temperatures. Forest Service research note  

SciTech Connect

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.

Trials of mixed-conifer plantings for increasing diversity in the lodgepole pine type. Forest Service research note  

SciTech Connect

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.

Gelsolin variant (Asn-187) in familial amyloidosis, Finnish type.  

PubMed Central

Familial amyloidosis, Finnish type (FAF), is an inherited form of systemic amyloidosis clinically characterized by cranial neuropathy and lattice corneal dystrophy. We have demonstrated that the protein subunit isolated from amyloid fibrils shows considerable sequence identity with gelsolin, an actin-binding protein. We have purified the amyloid subunit from a second case and further analysed different fractions from the previous one. Sequence analysis shows that, in both cases, the amyloid subunit starts at position 173 of the mature molecule; it has a heterogeneous N-terminus and contains one amino acid substitution, namely asparagine for aspartic acid, at position 15 (gelsolin residue 187), that is due to a guanine-to-adenine transversion corresponding to nucleotide-654 of human plasma gelsolin cDNA. The substitution maps in a fragment with actin-binding activity and is located in a repetitive motif highly conserved among species. Thus FAF is the first human disease known to be caused by an internal abnormal degradation of a gelsolin variant. We designate this variant of gelsolin-associated amyloidosis 'Agel Asn-187'.

Media portrayal of older people as illustrated in Finnish newspapers  

PubMed Central

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.

A mortality study of Finnish pulp and paper workers.  

PubMed Central

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

High and unchanged sperm counts of Finnish men.  

PubMed

Several recent reports have suggested that the sperm counts of normal men are declining in most countries. In this study the sperm counts of Finnish men, and their possible changes during the past 28 years, were investigated. The material consisted of semen samples from 238 normal healthy men of unknown fertility and 5481 men from infertile couples. The means (medians) of semen volume, sperm density and total sperm count in normal men were 3.3 (3.0) ml, 133.9 (94.0) x 10(6)/ml and 396.6 (309.0) x 10(6), respectively. These parameters and the relative frequency distribution of the sperm density were similar to those reported elsewhere in the 1940s. Multiple linear regression analysis revealed a significant decrease in semen volume, whereas sperm density and total sperm count of infertile men had not changed significantly during the past 28 years. In addition, no change in sperm counts was associated with the year of men's birth. PMID:8698532

Adsorption of sugar beet herbicides to Finnish soils.  

PubMed

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

Allometric biomass estimators for aspen-dominated ecosystems in the upper Great Lakes. Forest Service research paper  

SciTech Connect

The authors recently described the climate, geology, soils, and the biotic structure and dynamics of four contrasting ecosystems dominated by quaking and bigtooth aspen (Populus tremuloides and P. grandidentata). Other papers describe how those ecosystems responded to perturbation. Common to most of those papers were biomass estimates for the tree and shrub layers. The authors derived the estimators from weight and dimensional analysis of a subsample of stems measured on sample plots. They found much variability among sites that could not be adequately explained by stand or soils data. These equations should be useful in estimating woody plant components of similar forests on upland soils in the Upper Great Lakes region.

Highly stocked coniferous stands on the Olympic Peninsula: chemical composition and implications for harvest strategy. Forest Service research paper  

SciTech Connect

This report presents an assessment of macronutrients and their distribution within highly stocked, stagnant stands of mixed conifers on the Quilcene Ranger District, Olympic National Forest, northwest Washington. These stands consisted of predominantly three species: western hemlock (Tsuga heterophylla), coast Douglas-fir (Pseudotsuga menzeisii), and western redcedar (Thuja plicata). Preliminary investigation suggests that the living crown contains a small portion of the nutrient capital on the site. Extracting this material from the site during harvest or site preparation should not pose a threat to future production of biomass. Bioassays suggested that no macronutrients were deficient for growth of Douglas-fir seedlings.

Unearthing Secrets of the Forest  

USGS Publications Warehouse

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 Antisocial Process Screening Device- Self-Report (APSD-SR) is a self-report measure for assessment of psychopathic traits in adolescents. The present study aimed to investigate the factor structure and internal consistency of the APSD-SR in a sample of 4855 Finnish community adolescents. A three-factor structure with factors representing impulsivity (IMP), narcissism (NAR) and callous-unemotional (CU) features was found. Internal consistency indices ranged from moderate to good. The findings provide promising data on applicability of the APSD-SR instrument to Scandinavian youth. Results have implications for researchers and clinicians interested in measuring adolescent psychopathy. PMID:25190497

Distribution of biomass and nutrients in lodgepole pine/bitterbrush ecosystems in central Oregon. Forest Service research paper  

SciTech Connect

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.

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.

Family history (FH) is one of the few known risk factors for prostate cancer (PC). There is also new evidence about mortality reduction in screening of PC with prostate-specific antigen (PSA). Therefore, we conducted a prospective study in the Finnish Prostate Cancer Screening Trial to evaluate the impact of FH on outcomes of PC screening. Of the 80,144 men enrolled, 31,866 men were randomized to the screening arm and were invited for screening with PSA test (cut-off 4 ng/ml) every 4 years. At the time of each invitation, FH of PC (FH) was assessed through a questionnaire. The analysis covered a follow-up of 12 years from randomization for all men with data on FH. Of the 23,702 (74.3%) invited men attending screening, 22,756 (96.0%) provided information of their FH. Altogether 1,723 (7.3%) men reported at least one first-degree relative diagnosed with PC and of them 235 (13.6%) were diagnosed with PC. Men with a first-degree FH had increased risk for PC (risk ratio (RR) 1.31, p?

Risk factors for skin cancer among Finnish airline cabin crew.  

PubMed

Increased incidence of skin cancers among airline cabin crew has been reported in several studies. We evaluated whether the difference in risk factor prevalence between Finnish airline cabin crew and the general population could explain the increased incidence of skin cancers among cabin crew, and the possible contribution of estimated occupational cosmic radiation exposure. A self-administered questionnaire survey on occupational, host, and ultraviolet radiation exposure factors was conducted among female cabin crew members and females presenting the general population. The impact of occupational cosmic radiation dose was estimated in a separate nested case-control analysis among the participating cabin crew (with 9 melanoma and 35 basal cell carcinoma cases). No considerable difference in the prevalence of risk factors of skin cancer was found between the cabin crew (N = 702) and the general population subjects (N = 1007) participating the study. The mean risk score based on all the conventional skin cancer risk factors was 1.43 for cabin crew and 1.44 for general population (P = 0.24). Among the cabin crew, the estimated cumulative cosmic radiation dose was not related to the increased skin cancer risk [adjusted odds ratio (OR) = 0.75, 95% confidence interval (CI): 0.57-1.00]. The highest plausible risk of skin cancer for estimated cosmic radiation dose was estimated as 9% per 10 mSv. The skin cancer cases had higher host characteristics scores than the non-cases among cabin crew (adjusted OR = 1.43, 95% CI: 1.01-2.04). Our results indicate no difference between the female cabin crew and the general female population in the prevalence of factors generally associated with incidence of skin cancer. Exposure to cosmic radiation did not explain the excess of skin cancer among the studied cabin crew in this study. PMID:23316078

Detailed internal characterisation of two Finnish landfills by waste sampling.  

PubMed

The aim of this study was to characterise the internal structure and composition of landfilled waste at two Finnish landfills to provide information for active and post-landfill operations. The two sites, Ammssuo and Kujala, have been in operation for 17 and 48 years, respectively. Waste was sampled (total 68 samples) and analysed for total solids (TS), volatile solids (VS), total Kjeldahl nitrogen (TKN), biological methane potential (BMP) and leaching of organic material (determined as chemical oxygen demand, COD) and ammonium nitrogen (NH(4)-N). The results showed high vertical and horizontal variability, which indicated that both the waste composition and state of degradation varied greatly in both landfills. Ammssuo was characterised by 2- to 4-fold higher BMP, NH(4)-N and COD leaching than Kujala. Moreover, the ratio of VS to TS was higher at Ammssuo, while TS content was lower. The highest mean BMPs (68 and 44 m(3)/t TS), TKN content (4.6 and 5.2 kg/t dry weight) and VS/TS ratio (65% and 59%) were observed in the middle and top layers; and the lowest mean BMP (21 and 8 m(3)/t TS), TKN content (2.4 kg/t dry weight, in both landfills) and VS/TS ratio (55% and 16% in Ammssuo and Kujala, respectively) in the bottom layers. In conclusion, waste sampling is a feasible way of characterising the landfill body, despite the high variation observed and the fact that the minimum number and size of samples cannot easily be generalized to other landfills due to different methods of waste management and different landfilling histories.

Defining and Measuring Technical Thinking: Students' Technical Abilities in Finnish Comprehensive Schools  

NSDL National Science Digital Library

The terms "technical" and "technology" are widely used by educators, workplace practitioners, and the general public. Seldom, however, is there a written explanation of a technologist's or technician's attributes (Hansen, 1994; Ropohl, 1997). What do technicians know and do? Also absent from public consciousness is a sense of what constitutes the design or problem-solving process which precedes any technological act. By comparison, media depictions of technology as computers, electronics, and tools are widespread and the public appetite for these depictions is extensive. In teacher education and in schooling itself the subject through which technical skills and knowledge are imparted suffers from confusion about definition as well. What is technical thinking? What is technical aptitude? Why is it that technology teachers can recognize this ability when it is observed in students but they, and educators generally, have difficulty documenting the essence of it in writing? To expose what it means to be a technologist, the investigators in this research project examine what students in Finland's schools learn in their study and practice of technology. Why, you might ask, would the authors attempt to better understand what it means to have a technical orientation or technical ability by studying school children, in this case Finnish children? The answer has two parts. First, from a research perspective, children's responses to adult inquiries are often more informative and authentic than those of adults. Secondly, teachers of technology have had to think about their field, especially how to teach it. In doing so, they have to know about the substance of their subject. By comparison, practicing technicians and technologists may not have been required to think through what they know and do, much less express it. Target Audience: General Public

Wind Dynamics and Forests  

NSDL National Science Digital Library

In this activity, students will set up a model forest using plastic bottles to observe changes caused by differences in wind speed and forest density. An extension to the activity will allow students to explore the concept of evapotranspiration. From this activity students will understand that living organisms in an ecosystem can have profound effects upon the local atmosphere, changes in vegetation can have profound effects upon wind speed, and models are useful to researchers in understanding the shaping of ecosystems. The teacher's guide contains detailed background material, learning goals, alignment to national standards, grade level/time, details on materials and preparation, procedure, assessment ideas, and modifications for alternative learners.

Landscape dynamics of northeastern forests  

NASA Technical Reports Server (NTRS)

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.

Mechanical and chemical release in a 12-year-old ponderosa pine plantation. Forest Service research paper  

SciTech Connect

A 12-year-old ponderosa pine plantation on the Tahoe National Forest in northern California was mechanically treated with a Hydro-Ax in an attempt to increase the survival and growth of the planted seedlings. Other release methods were not feasible because the shrubs in the mixed-shrub community (greenleaf manzanita, mountain whitethorn, bittercherry, coffeberry) were too large (3 to 5 feet tall) and well developed. Additional treatments were a chemical treatment, in which 2,4-D was applied to a portion of the study site that had been treated with the Hydro-Ax 1 year previously, and control. Eleven growing seasons after treatment (1993), average pine crown cover was statistically higher in the mechanical treatment (Hydro-Ax alone) than in the control. This was the only significant enhancement of pine growth by the Hydro-Ax alone. Mean pine diameter and height did not differ statistically from the control after 11 years. In contrast, the Hydro-Ax plus herbicide (chemical) treatment statistically increased pine crown cover, height, and diameter over the Hydro-Ax alone and the control. Mean crown cover was 104 percent greater in the treated trees than for pines in the control, height was 45 percent greater, and diameter was 47 percent greater. Relative costs were $225 per acre for the Hydro-Ax alone (mechanical) and $273 per acre for the Hydro-Ax + herbicide (chemical). Altogether, the most cost-effective treatment was Hydro-Ax + herbicide (chemical).

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.

CTFS-ForestGEO: a worldwide network monitoring forests in an era of global change.  

PubMed

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 25ha), all stems ?1cm diameter are identified to species, mapped, and regularly recensused according to standardized protocols. CTFS-ForestGEO spans 25S-61N 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 0.61C), changes in precipitation (up to 30% change), atmospheric deposition of nitrogen and sulfur compounds (up to 3.8g Nm(-2) yr(-1) and 3.1g Sm(-2) yr(-1) ), and forest fragmentation in the surrounding landscape (up to 88% reduced tree cover within 5km). 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.

GenotypePhenotype Correlations in Non-Finnish Congenital Nephrotic Syndrome  

PubMed Central

Mutations in NPHS1, which encodes nephrin, are the main causes of congenital nephrotic syndrome (CNS) in Finnish patients, whereas mutations in NPHS2, which encodes podocin, are typically responsible for childhood-onset steroid-resistant nephrotic syndrome in European populations. Genotypephenotype correlations are not well understood in non-Finnish patients. We evaluated the clinical presentation, kidney histology, and disease progression in non-Finnish CNS cases by mutational screening in 107 families (117 cases) by sequencing the entire coding regions of NPHS1, NPHS2, PLCE1, WT1, LAMB2, PDSS2, COQ2, and NEPH1. We found that CNS describes a heterogeneous group of disorders in non-Finnish populations. We identified nephrin and podocin mutations in most families and only rarely found mutations in genes implicated in other hereditary forms of NS. In approximately 20% of cases, we could not identify the underlying genetic cause. Consistent with the major role of nephrin at the slit diaphragm, NPHS1 mutations associated with an earlier onset of disease and worse renal outcomes than NPHS2 mutations. Milder cases resulting from mutant NPHS1 had either two mutations in the cytoplasmic tail or two missense mutations in the extracellular domain, including at least one that preserved structure and function. In addition, we extend the spectrum of known NPHS1 mutations by describing long NPHS1 deletions. In summary, these data demonstrate that CNS is not a distinct clinical entity in non-Finnish populations but rather a clinically and genetically heterogeneous group of disorders. PMID:20507940

Hyperspectral forest monitoring and imaging implications  

NASA Astrophysics Data System (ADS)

The forest biome is vital to the health of the earth. Canada and the United States have a combined forest area of 4.68 Mkm2. The monitoring of these forest resources has become increasingly complex. Hyperspectral remote sensing can provide a wealth of improved information products to land managers to make more informed decisions. Research in this area has demonstrated that hyperspectral remote sensing can be used to create more accurate products for forest inventory (major forest species), forest health, foliar biochemistry, biomass, and aboveground carbon. Operationally there is a requirement for a mix of airborne and satellite approaches. This paper surveys some methods and results in hyperspectral sensing of forests and discusses the implications for space initiatives with hyperspectral sensing

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 Hyytil 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.

[Forest health ecological risk assessment in China].  

PubMed

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.

Hydrological recovery in forested landscapes (Invited)  

NASA Astrophysics Data System (ADS)

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.

As climate change threatens global freshwater supplies, researchers are looking for better ways to manage water sources like snowmelt. Many regions of the world depend on annual snowmelt for water, and portions of these regions are also forested. Forest dynamics are complex and can vary widely depending on region, precipitation, altitude, and many other factors, which makes it difficult to determine whether dense forests retain snowpack or accelerate melt.

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.

Advances of air pollution science: from forest decline to multiple-stress effects on forest ecosystem services.  

PubMed

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.

Children with Specific Language Impairment in Finnish: The Use of Tense and Agreement Inflections  

PubMed Central

Children with specific language impairment (SLI) vary widely in their ability to use tense/agreement inflections depending on the type of language being acquired, a fact that current accounts of SLI have tried to explain. Finnish provides an important test case for these accounts because: (1) verbs in first and second person permit null subjects whereas verbs in third person do not; and (2) tense and agreement inflections are agglutinating and thus one type of inflection can appear without the other. Probes were used to compare the verb inflection use of Finnish-speaking children with SLI, and both age-matched and younger typically developing children. The children with SLI were less accurate, and the pattern of their errors did not match predictions based on current accounts of SLI. It appears that children with SLI have difficulty learning complex verb inflection paradigms apart from any problem specific to tense and agreement. PMID:21281548

Aim of the study was to examine the associations between parental age and autism spectrum disorders (ASD). Data were based on the FIPS-A (Finnish Prenatal Study of Autism and Autism Spectrum Disorders), a case-control study with a total of 4,713 cases with childhood autism (n=1,132), Asperger's syndrome (n=1,785) or other pervasive developmental disorder (PDD) (n=1,796), which were ascertained from the Finnish Hospital Discharge Register. Controls were selected from the Finnish Medical Birth Register. Conditional logistic regression models were used for statistical analyses. Advanced paternal age (35-49years) was associated with childhood autism in offspring, whereas advanced maternal age was associated with both Asperger's syndrome and PDD in offspring (35years or more and 40years or more, respectively). Teenage motherhood (19years or less) was associated with PDD in offspring. The main finding was that maternal and paternal ages were differentially associated with ASD subtypes. In addition to advanced parental age, teenage pregnancy seems to incur a risk for PDD in offspring. PMID:23479075

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.

Methodological challenges in using the Finnish Hospital Discharge Register for studying fire-related injuries leading to inpatient care  

PubMed Central

Background The objective was to examine feasibility of using hospital discharge register data for studying fire-related injuries. Methods The Finnish National Hospital Discharge Register (FHDR) was the database used to select relevant hospital discharge data to study usability and data quality issues. Patterns of E-coding were assessed, as well as prominent challenges in defining the incidence of injuries. Additionally, the issue of defining the relevant amount of hospital days accounted for in injury care was considered. Results Directly after the introduction of the ICD-10 classification system, in 1996, the completeness of E-coding was found to be poor, but to have improved dramatically around 2000 and thereafter. The scale of the challenges to defining the incidence of injuries was found to be manageable. In counting the relevant hospital days, psychiatric and long-term care were found to be the obvious and possible sources of overestimation. Conclusions The FHDR was found to be a feasible data source for studying fire-related injuries so long as potential challenges are acknowledged and taken into account. Hospital discharge data can be a unique and powerful means for injury research as issues of representativeness and coverage of traditional probability samples can frequently be completely avoided.

Characteristics of Finnish and Swedish intensive care nursing narratives: a comparative analysis to support the development of clinical language technologies  

PubMed Central

Background Free text is helpful for entering information into electronic health records, but reusing it is a challenge. The need for language technology for processing Finnish and Swedish healthcare text is therefore evident; however, Finnish and Swedish are linguistically very dissimilar. In this paper we present a comparison of characteristics in Finnish and Swedish free-text nursing narratives from intensive care. This creates a framework for characterising and comparing clinical text and lays the groundwork for developing clinical language technologies. Methods Our material included daily nursing narratives from one intensive care unit in Finland and one in Sweden. Inclusion criteria for patients were an inpatient period of least five days and an age of at least 16 years. We performed a comparative analysis as part of a collaborative effort between Finnish- and Swedish-speaking healthcare and language technology professionals that included both qualitative and quantitative aspects. The qualitative analysis addressed the content and structure of three average-sized health records from each country. In the quantitative analysis 514 Finnish and 379 Swedish health records were studied using various language technology tools. Results Although the two languages are not closely related, nursing narratives in Finland and Sweden had many properties in common. Both made use of specialised jargon and their content was very similar. However, many of these characteristics were challenging regarding development of language technology to support producing and using clinical documentation. Conclusions The way Finnish and Swedish intensive care nursing was documented, was not country or language dependent, but shared a common context, principles and structural features and even similar vocabulary elements. Technology solutions are therefore likely to be applicable to a wider range of natural languages, but they need linguistic tailoring.

Comparing forests across climates and biomes: qualitative assessments, reference forests and regional intercomparisons.  

PubMed

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.

The temporal and spatial variability in submeter scale surface roughness of seasonal snow in Sodankyl Finnish Lapland in 2009-2010  

NASA Astrophysics Data System (ADS)

snow surface roughness is an important parameter for remote sensing data analysis since it affects the scattering properties of the snow surface. To understand the phenomenon, snow surface roughness was measured near the town of Sodankyl, in Finnish Lapland, during winters 2009 and 2010 using a photogrammetry-based plate method. The images were automatically processed so that an approximately 1 m long horizontal profile was extracted from each image. The data set consists of 669 plate profiles from different times and canopy types. This large data set was used to study the temporal and spatial variability of seasonal snow surface roughness. The profiles were analyzed using parameters derived from the root mean square height (?) and correlation length (L) as functions of measured length. Also, the autocorrelation functions were calculated and analyzed. The (?) and (L) were found to be so strongly correlated (R2 ~ 0.97) that a more detailed analysis was made using only the scaling parameters derived from ?. These parameters are related to the distance dependence of the rms height. The results show that they react to different characteristics of the profiles and are therefore well able to distinguish between different types of snow. They also show a clear difference between midwinter snow and melting snow, and the effects of snowfall events and slower melting in forested areas are evident in the data.

Returning forests analyzed with the forest identity  

PubMed Central

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.

Non-timber forest products in rural Mali: a study of villager use  

Microsoft Academic Search

Malian Forest Service activities and policies have evolved since the beginning of colonialism under the assumption that forests and their products are the property of the government. Today the importance of involving local people in forest management is recognized. The purpose of this research was to determine the range of non-timber forest products local people use either for direct consumption
