Description:
As compared with extensive contiguous areas, small isolated habitat patches lack many species. Some species disappear after isolation; others are rarely found in any small patch, regardless of isolation. We used a 13-year data set of bird captures from a large landscape-manipulation experiment in a Brazilian Amazon forest to model the extinction-colonization dynamics of 55 species and tested basic predictions of island biogeography and metapopulation theory. From our models, we derived two metrics of species vulnerability to changes in isolation and patch area. We found a strong effect of area and a variable effect of isolation on the predicted patch occupancy by birds.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ferraz, Goncalo -- Nichols, James D -- Hines, James E -- Stouffer, Philip C -- Bierregaard, Richard O Jr -- Lovejoy, Thomas E -- New York, N.Y. -- Science. 2007 Jan 12;315(5809):238-41.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biological Dynamics of Forest Fragments Project, Instituto Nacional de Pesquisas da Amazonia, 69011 Manaus AM, Brazil. gferraz@inpa.gov.br〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17218527" target="_blank"〉PubMed〈/a〉
