Global biodiversity decline has prompted great interest in the effects of habitat modification and diversity on the functioning and stability of ecosystem processes. However, the applicability of previous modeled or mesocosm community studies to real diverse communities in different habitats remains ambiguous. We exposed standardized nesting resources for naturally occurring communities of cavi...

Climate change affects both habitat suitability and the genetic diversity of wild plants. Therefore, predicting and establishing the most effective and coherent conservation areas is essential for the conservation of genetic diversity in response to climate change. This is because genetic variance is a product not only of habitat suitability in conservation areas but also of efficient protectio...

Markets for biodiversity have generated much controversy because of the often unstated and untested assumptions included in transactions rules. Simple trading rules are favored to reduce transaction costs, but others have argued that this leads to markets that favor development and erode biodiversity. Here, I describe how embracing complexity and uncertainty within a tradable credit system for ...

An important question for salmon restoration efforts in the western USA is ‘How should habitat restoration plans be altered to accommodate climate change effects on stream flow and temperature?’ We developed a decision support process for adapting salmon recovery plans that incorporates (1) local habitat factors limiting salmon recovery, (2) scenarios of climate change effects on stream flow an...

A reliable species–area relationship holds true for a number of terrestrial systems. When species–area data are plotted on logarithmic axes, the slope bears strong consistency across taxa. This study examined effects of habitat space on the diversity of coral reef fish species. Because habitat space on coral reefs is 3-dimensional, we developed and employed a methodology that accounts for volum...

the fish assemblage and diversity in relation to water quality of three coastal rivers sita, swarna and varahi of udupi district, karnataka, india was studied. 71 species representing 7 orders, 20 families and 41 genera were recorded from 21 sites along the three rivers. species composition varied longitudinally in relation to the environmental factors of the habitat. the downstream change in t...
