Formation of aggregated settlements as an expression of synanthropization of the long-eared owl (<Emphasis Type="Italic">Asio otus</Emphasis> L.)

The structure of the long-eared owl (Asio otus L.) settlements in anthropogenic landscapes has been studied in the Zhuravlinaya Rodina protected territory in the northern Moscow region in 2001–2005. The possible factors that cause the formation of such settlements have been analyzed. The differences in the breeding success between owls nesting near and away from human settlements have been estimated. Aggregated nesting of owls is assumed to be mainly related to a lower predator pressure in the vicinity of human dwellings in the incubation period. Aggregated nesting is regarded as an expression of synanthropization of the species.

Decomposition of factors influencing carbon emissions in the region of Beijing-Tianjin-Hebei,based on the perspective of terminal energy consumption

In order to analyze the factors influencing carbon emissions in the region of Beijing-Tianjin-Hebei and to explore the pathways to developing a low-carbon economy,this paper begins with the terminal energy consumption of three industries and residential consumption,and constructs an identical equation which is composed of population size,level of economic development,energy intensity,the proportion of energy consumption,energy structure,and the coefficient of carbon emissions.Based on the data of terminal energy consumption during 2000-2012,various factors are analyzed and their contribution is measured by Logarithmic Mean Divisia Index(LMDI).The results show that the levels of population and economy have a positive driving effect while energy intensity,energy structure,and carbon intensity have a negative driving effect;the proportion of energy consumption had a negative driving effect prior to 2006,then changed to positive.Among suggestions for a low-carbon economy are controlling population size,improving the quality of economic development,supporting research into new energy technology,accelerating regional integration and optimizing industrial structure,and enhancing environmental protection and spreading the concept of a low-carbon economy.     

Environment security: an empirical study of industrialization and the impact on environment in the Dhaka division, Bangladesh

Dhaka division is the main central industrial zone in Bangladesh. Along with the great growth in industry in the region, there have also been increased and sometimes critical levels of toxic pollution to the environment. Although much has been researched in the region on the degradation of the environment, the slow improvements in environment protection drive the question of what is the environmental security climate in Dhaka division. The study of four plants (textile, leather tanning, cement and fertilizer) in Dhaka division aimed to find out the impact of each on the environment. The study took place within Tejgaon, Hazaribagh, Narsingdi and Narayangang and investigated the impact of those plants on air, water and land. Among the different polluters, the results indicated that textiles polluted most. All participants indicated that the industries were the cause of at least one ailment within 6?months. It is recommended to governments and plant owners that they not only remain diligent about policy on environment protection, but that they also humanize efforts so as to follow those policies through to the end. The loss of life and quality of life may have larger impacts that daily profitability and livelihood.     

Developmental Disturbances in the Progeny of Sea Urchins as an Index of Environmental Pollution

The development of the progeny of Strongylocentrotus intermedius sea urchins collected in September 1999 at six stations of Peter the Great Bay (the Sea of Japan) was studied. No significant differences between the samples in the number of anomalies were observed at the earliest stages of embryogenesis (fertilization and the first cleavage division). The greatest deviation from normal development was observed in the progeny of sea urchins from station 1. The relationship between disturbances in the reproductive function of sea urchins and the level of heavy metal pollution of the Amur Bay ecosystem, as well as the usefulness of various indices characterizing the quality of the sea urchin progeny from the bioindication standpoint are discussed.

Supporting climate change vulnerability and adaptation assessments in the Asia-Pacific region: an example of sustainability science

Sustainability is achieved only when there is full reconciliation between: (1) economic development; (2) meeting, on an equitable basis, growing and changing human needs and aspirations; and (3) conserving the limited natural resources and the capacity of the environment to absorb the mulitple stresses that are a consequence of human activities. The linkages between climate and sustainability are examined in the context of both the wider Asia-Pacific region and local level climate risks and adaptation responses. These findings are used to underpin and illustrate several implications for sustainability science. Climate change is seen as both an impediment to increasing sustainability and as an opportunity, though in most cases the former far outweighs the latter. Assessments of climate change vulnerability and risk are shown to be of critical importance because they inform decisions as to where resources for adaptation are best invested. They also show whether global efforts to reduce greenhouse gas emissions need to be strengthened because of limits to adaptation. In practice, adaptation takes place at many levels, essentially ranging between tangible interventions at community and enterprise level and national and international efforts to strengthen the enabling environment for adaptation. It is informative to undertake regional assessments of adaptation, even though most adaptation interventions need to reflect local conditions, including local adaptive capacities. The foregoing findings, based in part on a series of regional and local case studies, lead to several recommendations for further research that will help reduce barriers to implementing responses that reduce climate related risks, including adverse consequences for sustainability. The recommendations relate to such themes as making optimum use of predictive capabilities, characterising the linkages between climate change and sustainability, implications of the required rates and magnitudes of adaptation, institutional responses that enhance adaptive capacity, use of new and traditional technologies, the multiple dimensions of social responsibility, and enhancing the enabling environment for adaptation at the community and enterprise level. If these recommendations are acted upon they will, in turn, help address much needed improvements in quantifying the costs and benefits of adaptation, prioritising adaptation options, assessing sustainable development tradeoffs, and monitoring the success of adaptation initiatives. Such improvements will have even greater utility if they are incorporated into user-friendly decision support tools for adaptation.     

Spatial population structure in forest voles of the genus <Emphasis Type="Italic">Clethrionomys</Emphasis> in the southern taiga of the Middle Irtysh region

A comparative analysis of spatial population structure in the northern red-backed vole (Clethrionomys rutilus Pall.) and large-toothed red-backed vole (Cl. rufocanus Sund.) has been performed in the middle taiga zone of the Middle Irtysh region (Omsk oblast). Populations of these species are represented by sets of territorial groups whose numbers and spatial distribution change from year to year depending on the ratio of these species in a biotope and their population density. There is no significant interspecific competition between cohabitant Cl. rutilus and Cl. rufocanus. In particular, this follows from the fact that the population density and distribution pattern of one species are independent of those of the other species. It has been found that the size of home ranges in Cl. rutilus inversely depends on its population density, with that in Cl. rufocanus remaining approximately the same at different population densities, and that the structure of the resident part of the population in both species changes during the season, as voles from neighboring habitats or dispersing voles settle in the study area.     

Cosmogenic 22Na as an index of the residence time of water in freshwater basins: a review

The goal of this review is to draw attention to an opportunity for the use of cosmogenic (22)Na for dating young surface and underground waters. After 1961 when a significant quantity of (22)Na was released into the environment as a result of nuclear weapon tests, its concentrations in river waters were greatly increased, and a return to natural (cosmogenic) levels took until the mid-1980s. The studies made during this non-steady-state period showed that the one-box model for freshwater basin correctly describes the experimental data. For the 19 studied basins of Russia, the Baltic States and Japan, a calculation based on this model gave values for the mean residence time of water in the range from 4 to 23 years. Now, only cosmogenic (22)Na is in the environment, and it is the single cosmogenic radionuclide at present, which can serve as a steady-state tracer for dating young waters (up to some decades).     

Estimates of energy expenditures for reproduction in the pied flycatcher Ficedula hypoleuca Pall. in an industrially polluted environment

Energy expenditures for reproduction in local populations of the pied flycatcher in the environs of the Middle Urals Copper Smelter (Revda, Sverdlovsk oblast) have been estimated on the basis of the results of long-term studies (1989?C2008). It is shown that the total energy expenditures per fledgling over the nesting period are 1.2 times higher than in the background area, which is explained by increased energy losses (by a factor of 4.1) resulting from partial mortality of the progeny (eggs or nestlings). Variation in the average energy ??cost?? of one fledgling in the heavily polluted zone is also higher, compared to the background area. Average energy expenditures per fledgling increase in years with cold weather, and the same is observed when the birds lay larger clutches.     

Arsenic contamination of groundwater in the Terai region of Nepal: an overview of health concerns and treatment options

A review of published information on the arsenic contamination of groundwater in the Terai regions of Nepal showed that the source was mainly geogenic due to the dissolution of the arsenic-bearing minerals. Clinical observations of patients in the arsenic affected districts revealed chronic arsenic poisoning from drinking water. Half a million people inhabiting the region are believed to have been exposed to arsenic levels greater than 50 microg/L in their drinking water. Thirty-one percent of the population (3.5 million) in the region are estimated to have been exposed to arsenic levels between 10 and 50 microg/L. Iron assisted biosand filters currently distributed and in operation are a suitable alternative to mitigate the interim arsenic standard of 50 microg/L, as set by the Nepal Government. Arsenic biosand filters were also effective in removing bacteria and viruses from drinking water in laboratory and field tests. However, groundwater treatment targeting cluster communities in the Terai region is the sustainable way of mitigating the arsenic problem.     

Impacts of snow disaster on meat production and adaptation: an empirical analysis in the yellow river source region

The Yellow River source region is located in the hinterland of the Qinghai-Tibetan Plateau, and has a sensitive response to global change due to its unique cryosphere processes. Any slight changes in natural elements and human activity can have a magnified effect on grassland ecosystem, animal husbandry, and pastoral livelihoods since its economy is exclusively dominated by grassland animal husbandry. Because snow disaster has been one of the major natural disasters in the source region, it is crucial to explore the economic impact of snow disaster on animal husbandry and identify effective adaptation measures. A nonlinear model of meat production was established in relation to snow disaster, grassland productivity, and disaster prevention by introducing a snow level index, and selecting three key indicators of grassland productivity and disaster prevention, including grass growing season precipitation concentration, sown grassland area, and warm barn area. This is an inverse of negative correlation, less meat when there is more snow. Per unit increase in snow level in the source region led to a decrease of 0.213 units in meat production. However, production losses caused by the snow disaster could be effectively suppressed by the increase in scale and intensity of sown grassland and warm barn construction. Per unit increase in sown grassland and warm barn area led to an increase of 0.240 and 0.610 units in meat production, respectively. The effects of sown grassland and warm barn area in reducing snow damage at different snow levels were analyzed. Snow disaster adaptation in the source region should include acceleration of the construction of meteorological disaster prevention and mitigation system, to ensure balanced forage supply between winter and spring, to prioritize the development of warm barn, and reduce the proportion of self-financed construction warm barn to encourage active participation of pastoralists, and to develop insurance mechanism for livestock.     

Interpopulation variation in morphometric characteristics of the ant <Emphasis Type="Italic">Myrmica angulinodis</Emphasis> Ruzs. (Hymenoptera: Formicidae) in the Baikal region

The effect of geographic origin on morphometric characteristics of ants has been studies by means of one-way ANOVA using 120 worker specimens of M. angulinodis from four population groups inhabiting different parts of the Baikal region. Similarity between the population groups has been evaluated using cluster analysis. The results show that worker specimens in populations from areas with lower air temperatures have significantly greater body size and that ants with an elongated head and more strongly curved frontal carinae dominate in the south of Irkutsk oblast, while ants with a wider frons prevail in the south of the Republic of Buryatia.     

Analysis of the soil water balance for large-scale reforestation with <Emphasis Type="Italic">Eucommia ulmoides</Emphasis> in the hilly red soil region of southern China

Returning farmland to forests is important for the protection of ecological values. Eucommia ulmoides is considered to be a suitable species for reforestation in the hilly red soil region of southern China. The objective of this study was to investigate the relationship between the water supply and demand of an E. ulmoides plantation to provide insights into the feasibility of large-scale planting for ecological restoration and forest management activities in the hilly red soil region of southern China. With the measured precipitation, surface runoff and interflow and actual evapotranspiration (ET_c) estimated by the modified P–M model, soil water storage (SWS) was estimated based on the water balance equation. Monthly variations of SWS were then compared with in situ measured SWS. The results showed that the estimated mean monthly water losses (the sum of the surface runoff, interflow and ET_c) were 139.8 mm in a wet year and 120.0 mm in a dry year, while the measured mean monthly water input values (net precipitation) were 131.2 mm in a wet year and 70.8 mm in a dry year. Net soil water storage (ΔSWS) was negative in each month of the growing season in a dry year, but the soil water deficit was replenished during the following season. The model performance showed that the modified P–M model can be adapted to estimate the soil water storage in other forest catchments where no adequate in situ data are available. As a result of estimating the water balance and observing soil water storage in two different hydrological years, E. ulmoides is recommended as a suitable forest rehabilitation species in the study area, and a suitable plant region has been defined by the GIS technique based on the water balance model.     

Influence of spruce and pine on the acidity and composition of atmospheric fallout in north taiga forests of an industrially developed region

The ideas concerning the spatial and temporal variation of acidity and composition of atmospheric fallout in forests of the boreal zone are discussed. The role played by the atmospheric component in the functioning of these forests depends on the acidity and composition of fallout and the extent of their transformation by the biocenosis. The most profound transformation of fallout occurs during the growing season. In spaces between crowns, the corresponding changes are atmogenic; in undercrown areas, they are obviously biogenic (autogenic). Spruce transforms the fallout more intensively than pine. Under conditions of industrial pollution, the atmobiogenic character of fallout is supplemented with a technogenic component, as its acidity and concentration of pollutants and other elements sharply increase. Concentrations of principal cations reach high values because of their leaching from the crown by acid precipitation. The traditional concept of atmospheric load on boreal forests should be reconsidered taking into account their spatial structure.     

The in-use annual energy and carbon saving by switching from a car to an electric bicycle in an urban UK general medical practice: the implication for NHS commuters

The UK Climate Change Act (CCA) mandates an 80 % reduction in CO₂ emissions by 2050. It is estimated that 3.2 M tonnes pa CO₂ results from travel-related NHS business. The acquisition of an electric bicycle to replace a car for both commuting and home visits allowed comparison of fuel use and CO₂ emissions over a 4-year period. The switch to the use of the electric bicycle reduced the average annual petrol use by 329 l, the energy consumption by 3,140 kWh and the CO₂ released by 748 kg a year. Wider adoption of electric bicycles in urban General Practice will contribute to the requirements of the CCA though to have a significant effect on the current estimated commuting-related carbon footprint of the NHS (0.76 MT pa) would require two-thirds of the workforce to abandon their cars in favour of electric bicycles.
