Island biogeography is an important subject for several reasons. First, it has been and remains a field which feeds ideas, theories, models, and tests of same into ecology, evolutionary biology, and biogeography. This is because islands provide natural scientists with model systems—replicated and simplified contexts—allowing us to isolate particular factors and processes and to explore their effects. Secondly, some of these theories have had great weight placed upon them in applications in nature conservation, as scientists and conservationists attempt to understand, predict and manage the biodiversity impacts of habitat loss and fragmentation
