Mean Time To Extinction Of A Metapopulation With An Allee Effect, Chad Brassil
Mean Time To Extinction Of A Metapopulation With An Allee Effect, Chad Brassil
School of Biological Sciences: Faculty Publications
The incorporation of Allee effects into a simple metapopulation extinction model reveals a large non-linear reduction in mean time to extinction with small changes in an Allee limit. The extent of this reduction is dependent on the level of migration in the metapopulation. With small amounts of migration, small changes in the Allee limit result in large changes in the meantime to extinction. With higher levels of migration, the mean time to extinction is not as sensitive to changes in the Allee limit, becoming more similar to the single population case. The metapopulation modeled here is a set of nine …
