Adaptation in a metapopulation : a stochastic eco-evolutionary model
By Nick Barton
Joint work with Himani Sachdeva, Eniko Szep and Oluwafunmilola Olusanya.
The joint distribution of allele frequencies and deme size across a metapopulation can be analysed using the diusion approximation. Szep et al. (Evolution, 2021) derive an explicit formula for the stationary distribution, and nd when a heterogeneous environment can maintain genetic variation. If loci are typically close to xation, we can make a further approximation, which allows us to follow change through time.
