Collaborative Research: Land-Use Practices And Persistence Of Amphibian Populations, Malcolm L. Hunter Jr.

University of Maine Office of Research Administration: Grant Reports

Over the past 200 years, conversion of land for agricultural use, industrial development, and urban sprawl has drastically reduced natural habitat for many species and is considered the most serious threat to biological diversity. Fragmentation divides once continuous natural habitats into smaller pieces that are often separated by areas unsuitable to sustain viable populations. The goal of the proposed research is to understand how important local population and metapopulation processes are altered by fragmentation of natural habitats in a model system of pond-breeding amphibians. The primary objectives of the proposed study are to experimentally compare demographic and behavioral responses of …
