Biologists seek an understanding of the biological and environmental factors determining local community diversity. Recent advances in metacommunity ecology, and neutral theory in particular, highlight the importance of dispersal processes interacting with the spatial structure of a landscape for generating spatial patterns and maintaining biodiversity. The relative spatial isolation of a commu...
Monitoring and research activities may hinder rather than improve conservation in tropical countries. Those concerned with conservation—particularly academics and aid agencies—too often overlook the practical realities of achieving conservation in the tropics. As a result, many initiatives divert scarce resources away from fundamental management priorities. I identify some critical threats to b...
Biodiversity in tropical and subtropical forests are at high risk of decline due to rapid anthropogenic development. Planned activities that potentially benefit communities near often undertaken the expense forest biodiversity. Recently, Government Bangladesh released plans develop a safari park Lathitila northeastern Bangladesh. This mixed evergreen, stream-fed, trans-border harbors 26 globall...
Freshwater biodiversity is under threat worldwide, but the intensity of threat in the Oriental biogeographic region of tropical Asia is exceptional. Asia is the most densely populated region on Earth. Many rivers in that region are grossly polluted, and significant portions of their drainage basins and floodplains have been deforested or otherwise degraded. Flow regulation has been practiced fo...
Researchers working with biodiversity try to understand organisms adaptation in their environmental niche and try to provide subsidies for conscious use of natural resources by scientific organizations and government institutions. This work aims to support the cooperation among the researchers of a species distribution modeling network. The cooperation is based on sharing modeling results, whic...
Acknowledgements: We would like to thank the participants of the IVM-PBL review workshop on international biodiversity policies (29 November 2010, Utrecht) for their many helpful comments on an earlier version of this report.
