Extinction vortices and minimum viable populations: Interactions between ecology and evolution and between different selection mechanisms
A talk in the Keine Reihe series by
Meike Wittmann
| Abstract: |
Small populations can suffer from genetic problems like inbreeding depression, mutation accumulation, and loss of genetic variation. In this talk, I will present stochastic models for the joint dynamics of population sizes and allele frequencies in such populations. We explore under what conditions populations enter an eco-evolutionary extinction vortex where a decrease in genetic variation leads to population decline, which leads to even faster loss of genetic variation, and so on, until the population goes extinct. We will also quantify minimum viable population sizes for the long-term persistence of populations experiencing a combination of genetic problems of small population size. This is joint work with Peter Nabutanyi
