Increased appreciation of uses and threats is essential to protect wetlands where justified. Three quarters of India's population is rural, it places great demands on India's wetlands and losses ... ...

A review of methods for the assessment of prediction errors in conservation presence/absence modelsPredicting the distribution of endangered species from habitat data is frequently perceived to be a useful technique. Models that predict the presence or absence of a species are normally judged by the number of prediction errors. These may be of two types: false positives and false negatives. Many of the prediction errors can be traced to ecological processes such as unsaturated habitat a... ...

Sustainability science: a review, an analysis and some empirical lessonsSUMMARY Sustainability science has developed from a new research field into a vibrant discipline in its own right, with scientific conferences, journals and scientific societies dedicated to its pursuit. Characterized more by its research purpose than by a common set of methods or objects, sustainability science can be subdivided into the more traditional disciplina... ...

Factors influencing success among collaborative sage-grouse management groups in the western United StatesSUMMARY Considerable efforts have been put into collaborative conservation efforts across the globe. In the western USA, concern about declines of two sage-grouse species (Centrocercus urophasianus and C. minimus ) has led to the creation of over 60 collaborative wildlife management partnership groups to develop a... ...

Threats to the running water ecosystems of the worldRunning waters are perhaps the most impacted ecosystem on the planet as they have been the focus for human settlement and are heavily exploited for water supplies, irrigation, electricity generation, and waste disposal. Lotic systems also have an intimate contact with their catchments and so land-use alterations affect them directly. Here long-term trends in the factors that currently impa... ...

Resources use, conservation attitudes, management intervention and park-people relations in the Western Terai landscape of NepalVarious conservation models have been implemented in Nepal since 1973, however their impacts on resources use and conservation attitudes are scarcely known. To address the hypothesis that conservation attitudes should improve around protected areas (PAs) with more social and economic interventions, stratified random questionnaire surveys of 234 households were conducted in two PAs in the W... ...

Heavy-metal Pollution in the Sudbury Mining and Smelting Region of Canada, I. Soil and Vegetation Contamination by Nickel, Copper, and Other MetalsSoil, vegetation, and rainfall, have been collected in the vicinity of a nickel–copper smelter at Sudbury, Ontario. The region is a major producer of many metals, and the large areas of forest desolation in the vicinity have been ascribed to sulphur dioxide fumigations over the past 80 years. In the present study, attention has been focused on potentially toxic heavy metals. Very elevated ... ...

Biophysical and policy drivers of landscape change in a central Vietnamese districtConservation in a dynamic setting requires understanding the factors leading to landscape change. This study integrated traditional remote sensing and geographic information systems analysis techniques with a narrative policy analysis to assess the 1975–2004 land cover changes and their determinants in Nam Dong district (central Vietnam). Total forest cover of Nam Dong remained stable, but... ...

The continental shelf benthic ecosystem: current status, agents for change and future prospectsContinental shelf benthic ecosystems play an important role in the economy of many coastal states through the provision of food, non-living resources and through control of climate. Changes in the status of these ecosystems, through either natural or human-induced environmental drivers can be expected to have important economic and social consequences. Agents that could induce change inclu... ...
