  1. Concern With Environmental Deterioration and Attitudes Toward Population Limitation

    ERIC Educational Resources Information Center

    Barnett, Larry D.

    1970-01-01

    Analysis of Gallup Poll data of Junuary 1969 reveals weak association between concern about environmental deterioration and the recognition of need for eventual limitation of human population. Suggests that to increase favorable attitudes to population control, role of overpopulation in causing environmental deterioration needs to be presented to…

  2. Environmental deterioration increases tadpole vulnerability to predation.

    Human-induced environmental change is occurring at an unprecedented rate and scale. Many freshwater habitats, in particular, have been degraded as a result of increased salinity. Little is known about the effects of anthropogenic salinization on freshwater organisms, especially at sublethal concentrations, where subtle behavioural changes can have potentially drastic fitness consequences. Using a species of Australian frog (Litoria ewingii), we experimentally examined the effects of salinization on tadpole behaviour and their vulnerability to a predatory dragonfly nymph (Hemianax papuensis). We found that tadpoles exposed to an ecologically relevant concentration of salt (15% seawater, SW) were less active than those in our freshwater control (0.4% SW). Tadpoles in elevated salinity also experienced a higher risk of predation, even though the strike rate of the predator did not differ between salt and freshwater treatments. In a separate experiment testing the burst-speed performance of tadpoles, we found that tadpoles in saltwater were slower than those in freshwater. Thus, it would appear that salt compromised the anti-predator response of tadpoles and made them more susceptible to being captured. Our results demonstrate that environmentally relevant concentrations of aquatic contaminants can, even at sublethal levels, severely undermine the fitness of exposed organisms. PMID:18492650

  6. [The ravages of environmental deterioration in Third World cities].

    PubMed

    Carty, W P

    1990-10-01

    2 articles examine different aspects of environmental deterioration in Third World cities. The 1st, by Winthrop Carty, notes that by the early 21st century the world's population will be predominantly urban for the 1st time. 3.5 billion persons will reside in cities covering 1% of the earth's land area. 90% of urban growth in the next 28 years will be in the least developed countries, and only 4 of the 23 largest cities in 2000 will be in the industrialized world. The current rate of urban growth in developing countries, 3.6%/year, is a result largely of influx from rural areas of migrants in search of a better life. Rapid urbanization was not unknown in Europe and North America, but it did not approach the speed of growth in the urban areas of developing countries today. The population of Lagos for example grew from 700,000 in 1965 to 5.6 million in 1985, and Cairo grew by nearly 6.5 million between 1947-81. Environmental degradation and a rapid decline in the quality of life have been among the results of this rapid urban growth. There is considerable evidence, however, that cities in developing countries are powerful motors of development. Nearly 60% of the gross national products of the least developed countries is generated in their urban areas by 1/3 of their total populations. Air pollution, lack of sewage disposal, and lack of potable water are among the most pressing environmental problems in urban areas of developing countries. The 30-60% of their populations who are the most impoverished are most vulnerable to the health problems resulting from environmental deterioration. But developing countries lack the substantial resources that would be needed to improve living conditions for their urban populations. The 2nd article, by Aliou Diongue, focuses on overly rapid and unplanned development in the cities of the Sahel. Although Sahel cities are not large in absolute terms, their recent very rapid growth has obliterated their identities. The growth rate of

  7. Phenotypic differentiation of the Red Sea gastropods in response to the environmental deterioration: Geometric morphometric approach

    The negative impacts of degradation in the coastal zone of the Red Sea are becoming well known in upper portions of the trophic web (e.g., humans and fish), but are less well known among the benthic primary consumers. In addition, the degree to which heavy metals are entering the trophic web can be better-quantified using macrobenthos. Two-gastropod genera encompassing Echinolittorina subnodosa and Planaxis sulcatus from three different localities on the Egyptian coast of the Red Sea were examined in order to deduce the impact of environmental deterioration on the morphology of shells. The examined sites include clean pristine, slightly polluted, and markedly polluted rocky shores. Phosphate/lead industry is the main source of pollution in this zone. Because landmarks on the rugose Echinolittorina are difficult to define and to ensure finer resolution of the analyses, a newly 'grid-based' landmarks was implemented. Both Canonical Variate Analysis (CVA) and Thin Plate Spline (TPS) were particularly capable to capture and terrace the minor morphological variations accurately. Two phenotypes portioned among the environmentally different populations were recognized and interpreted as ecotypes with many intermediate forms. The first ecotype has a higher spire and smaller aperture and dominating the pristine site North of Marsa Alam, whereas the second ecotype has a globular shell shape with big aperture and dominating the markedly polluted site. The intermediate forms dominating the slightly polluted site. The shape differences are interpreted as an adaptive differentiation to different metal concentrations. As the morphological variation between the two-ecotypes of both taxa is still minors, and both ecotypes occur together with many intermediate forms, the phenotypic divergence stage has not yet accomplished. The gradational shape change among the investigated populations was positively correlated with index of Pollution (IP). As the human activities were the main

    Genetic studies of South Asia's population history have led to postulations of a significant and early population expansion in the subcontinent, dating to sometime in the Late Pleistocene. We evaluate this argument, based on new mtDNA analyses, and find evidence for significant demographic transition in the subcontinent, dating to 35–28 ka. We then examine the paleoenvironmental and, particularly, archaeological records for this time period and note that this putative demographic event coincides with a period of ecological and technological change in South Asia. We document the development of a new diminutive stone blade (microlithic) technology beginning at 35–30 ka, the first time that the precocity of this transition has been recognized across the subcontinent. We argue that the transition to microlithic technology may relate to changes in subsistence practices, as increasingly large and probably fragmented populations exploited resources in contracting favorable ecological zones just before the onset of full glacial conditions.

    The Zsolnay products are one of the most famous Hungarian ceramics. The glazed building ceramics, which were produced by this factory, were often applied in Hungary and the surrounding countries. Since their outplacements the ceramics have suffered from numerous environmental and human influences. There is no profound knowledge about deterioration of these building materials. Beside the characterization of the Zsolnay ceramics, our purpose is to attempt to explain the deterioration caused by environmental factors considering that these ceramics have never been studied in this aspect before. Other goal is to reveal if there is any influence on the deterioration depending on the location of building covered by Zsolnay ceramics. The studied objects were used on buildings of the Museum of Applied Arts (in the center with high traffic) and the Hungarian Geological and Geophysical Institute in Budapest (in a quarter with moderate traffic). We examined the physical and chemical features of the glaze and the ceramic body (e.g., phase composition, texture, microstructure, alteration) and the depositions on the glazed and the unglazed sides of some selected ceramics. Based on the results, three different types of ceramics were used as building materials. We observed several kinds of damage (e.g. cracks, pitting corrosions), black deposition layer and alterations in different extent. Natural and artificial particles (e.g. iron-oxide, mica, calcite and glauberithe) and spherules were deposited on the surface. Traces of biological activity were also found and connected to these organic residues calcium-oxalate was detected. On some objects of the Museum the glaze has started to weather and its lead was leached glaze by rainfall. Weathering also occurs along cracks in the glaze interior together with precipitation of lead-rich phases. Gypsum layer frequently covers the ceramics. In conclusions, the ceramics from the Museum are in worse condition than the ceramics from the

  10. Valuation and the consequences of multiple sources of environmental deterioration: The case of the New York striped bass fishery

    Kahn, J.R. ); Buerger, R.B. )

    1994-03-01

    This paper examines two sources of environmental degradation in the New York striped bass fishery. The first is the decline in environmental quality in the Chesapeake Bay, the spawning ground for the majority of fish in New York waters. The second is the PCB contamination of striped bass from the Hudson River, the other primary spawning ground for striped bass in New York waters. The paper develops methodologies for examining loss in economic value, when the loss stems from two sources. The estimates resulting from the application of these methodologies suggest that the general deterioration of the Chesapeake Bay generated 2[center dot]3 to 7[center dot]7 million dollars in annual losses to the New York striped bass fishery, and that the annual losses from PCB contamination of the Hudson striped bass are between 0[center dot]745 and 3[center dot]7 million dollars. The paper also discusses how the dual sources of degradation generate barriers to the formation of effective management policy, and develops policy recommendations based on the estimated losses. 9 refs., 8 figs., 8 tabs.

  11. Methodology for Definition of Yellow Fever Priority Areas, Based on Environmental Variables and Multiple Correspondence Analyses

    PubMed Central

    Moreno, Eduardo Stramandinoli; Barata, Rita de Cássia Barradas

    2012-01-01

    Yellow fever (YF) is endemic in much of Brazil, where cases of the disease are reported every year. Since 2008, outbreaks of the disease have occurred in regions of the country where no reports had been registered for decades, which has obligated public health authorities to redefine risk areas for the disease. The aim of the present study was to propose a methodology of environmental risk analysis for defining priority municipalities for YF vaccination, using as example, the State of São Paulo, Brazil. The municipalities were divided into two groups (affected and unaffected by YF) and compared based on environmental parameters related to the disease's eco-epidemiology. Bivariate analysis was used to identify statistically significant associations between the variables and virus circulation. Multiple correspondence analysis (MCA) was used to evaluate the relationship among the variables and their contribution to the dynamics of YF in Sao Paulo. The MCA generated a factor that was able to differentiate between affected and unaffected municipalities and was used to determine risk levels. This methodology can be replicated in other regions, standardized, and adapted to each context. PMID:22802971

    The phytoplankton community in Hanfeng Lake Reservoir, located in the Three Gorges Reservoir Areas of Yangtze River, was investigated from Jun to August 2013. The results showed that 72 species belonging to 7 phyla of phytoplankton were detected in the water. The dominant species were Synedra, Navicula, Melosira, Cocconeis, Scenedesmus, Pseudoanabaena and Merismopedia. The phytoplankton at the entrance of Donghe River was mainly composed of Bacillariophyta, while that at the entrance of Nanhe River was dominated by Cyanophyta and Chlorophyta. Canonical correspondence analysis was applied to investigate the relationships between the distribution of phytoplankton and the environmental factors. The results showed that the species of phytoplankton at the entrance of the Donghe River were influenced by the physiochemical properties of the water, while those at the entrance of Nanhe River were affected by the nutrient status of the water. The key factors influencing the distributions of phytoplankton were temperature, dissolved oxygen (DO), pH, total nitrogen (TN), dissolved nitrogen (DN) and dissolved phosphorus (DP). PMID:25929059

  2. Environmental cues induce changes of steviol glycosides contents and transcription of corresponding biosynthetic genes in Stevia rebaudiana.

    Plant growth and secondary metabolism are commonly regulated by external cues such as light, temperature and water availability. In this study, the influences of low and high temperatures, dehydration, photoperiods, and different growing stages on the changes of steviol glycosides (SGs) contents and transcription levels of fifteen genes involved in SGs biosynthesis of Stevia rebaudiana Bertoni were examined using HPLC and RT-PCR. The observations showed that the transcript levels of all the fifteen genes were maximum under 25 °C treatment, and the transcription of SrDXS, SrDXR, SrMCT, SrCMK, SrMDS, SrHDS, SrHDR, SrIDI, SrGGDPS, SrCPPS1, SrUGT85C2 and SrUGT76G1 were restrained both in low temperature (15 °C) and high temperature (35 °C). Most genes in SGs biosynthesis pathway exhibited down-regulation in dehydration. To elucidate the effect of photoperiods, the plants were treated by different simulated photoperiods (8 L/16 D, 1 0L/14 D, 14 L/10 D and 16 L/8 D), but no significant transcription changes were observed. In the study of growing stages, there were evident changes of SGs contents, and the transcript levels of all the fifteen genes were minimal in fast growing period, and exhibited evident increase both in flower-bud appearing stage and flowering stage. The obtained results strongly suggest that the effect of environmental cues on steviol glycosides contents and transcription of corresponding biosynthetic genes in S. rebaudiana is significant. It is worth to study deeply. PMID:25500454

    2013-09-01

    Sponges have an important ecological role in coral reef ecosystems. However, when compared to other benthic Phyla, it has been little researched. This research was focused in the variability of the community structure of sponges in three locations at Morrocoy National Park (Cayo Sombrero, Playa Mero and Punta Brava) exposed to different environmental conditions (transparency and currents intensity) and affected in different degree of severity by a mass mortality event in 1996. A total of 15 transects (10 m long and 1 m wide) were evaluated in three strata (between 3 and 15 m depth) in each site, where all the individuals were counted by species. Relative abundance by species, diversity and evenness were calculated. Locations showed differences respect turbidity, wave and current intensity. 27 species were found in Morrocoy; Cayo Sombrero (23), Playa Mero (18) and Punta Brava (15). Agelas sceptrum, Amphimedon erina and Niphates erecta were the most common in first location; Niphates erecta and Dysidea etheria in Playa Mero and Dysidea etheria, Niphates erecta and Amphimedon erina in Punta Brava. The species composition showed statistical differences between all three locations; Cayo Sombrero resulted the most diverse and even, followed by Playa Mero and Punta Brava. According to Sorensen Similarity Index results, Cayo Sombrero and Playa Mero were more similar, while Punta Brava resulted the most different. The variability in environmental conditions and the differential mass mortality effects of 1996 in all three reefs, were probably the main causes of the differences between their sponge communities. Nevertheless, we cannot conclude about the weight of these factors. PMID:24027920

    Wood fibers were substituted for asbestos fibers as reinforcing in cement-fiber shingle products used as imitation roofing slate when governmental action outlawed the use of asbestos in this application. Field experience with many installations of one brand of these new products, however, has been unsatisfactory. The authors have observed the rapid deterioration, often within two to three years, of shingles in service, primarily by the development of extensive cracking. Research finds that these failures result from layering of the mortar materials during manufacture, combined with petrifaction and loss of ductility of the organic fibers. The authors suggest changes to the requirements of the applicable ASTM standard to help ensure that the product has the attributes necessary for satisfactory performance in service.

In winter, the average phytoplankton abundance is 254.88 x 10(4) cells x L(-1), and the Bacillariophyta abundance accounts for 62.3% of the total. While in summer, the average phytoplankton abundance is 2704.28 x 10(4) cells x L(-1), and the Cyanophyta abundance accounts for 93.5%. The relationship between 62 genus of phytoplankton and 11 environmental factors from 57 sampling sites in research area was studied by Canonical Correspondence Analysis. It suggests that water temperature, permanganate indexes, nitrate nitrogen and total nitrogen are the main environmental factors correlated with the distribution of phytoplankton community. And in winter, pH, ammonia nitrogen and total phosphorus are also the main environmental factors. Furthermore, the Bacillariophyta has higher adaptability to the changeable environment. The Chlorophyta can tolerate higher concentration of permanganate indexes, phosphorus nutrients, nitrogen nutrients and total organic carbon, whereas the response of Cyanophyta to environmental factors needs further research.

  9. Overcoming environmental deterioration through defensive expenditures: field evidence from Bahía del Tóbari (Sonora, México) and implications for coastal impact assessment.

    The costs of the maneuvers that fishermen and shrimp farmers have to undertake in a coastal scenario where both the access to navigable waters and water quality have decreased were interpreted as defensive expenditures. Maneuvers were prompted by profound changes in water circulation and siltation mode imposed by major shifts in regional and local land-use patterns. In coastal scenarios under heavy land-based discharges and local geomorphic modifications, local users with little chance to move away may modify their routines in order to maintain existing levels of utility. The concept of defensive expenditures could be used to assess social responses to adverse changes in environmental and resource conditions, as a means to distinguish stages in which local sectors respond individually from qualitatively different stages in which intersectoral events are more conspicuous.

  10. Punching Deterioration Mechanism of Magnetic Properties of Cores

    NASA Astrophysics Data System (ADS)

    Kaido, Chikara; Mogi, Hisashi; Fujikura, Masahiro; Yamasaki, Jiro

    This paper discusses the deterioration mechanism of magnetic properties of cores due to punching and proposes the modeling, as the best design of motors, considering manufacturing motors, is important in order to improve the high performance of motors corresponding to energy saving. In producing motors, magnetic cores with laminated steel sheets are made of punched sheets, and then the magnetic properties of steel sheets are deteriorated by plastic deformation and the induced residual stress due to punching. In this paper, the punching deterioration mechanism is investigated by observing magnetic domains at steel surfaces near sheared parts. Tensile and compressive stresses induced at cut steel edges deteriorate the magnetic properties of punched steel sheets in high flux densities as the compression deterioration is stronger than the tension improvement, and improve permeabilities at low magnetic field because the increases in permeabilities with tensile stresses are emphasized. Therefore, it is necessary to model the magnetic properties of motor magnetic cores, taking account of these magnetic phenomena.
