Dispersal and genetic structure
Estimating migration rates between pairs of demes in a metapopulation framework remains very challenging. We are currently trying to develop an "indirect" approach of backward migration based on the variations in sub-populations' allele frequencies during dispersal.
Individual-based simulations are used to evaluate the accuracy of the estimates, and we aim at measuring pairwise migration rates in a fragmented population of shrews (Crocidura russula) and in an endangered metapopulation of tree frogs (Hyla arborea) in Western Switzerland.
I'm interested in the effects of landscape features on gene flow in heterogeneous habitats. This interaction should allow us to infer some information about dispersal behaviour (what landscape features do facilitate or prevent population connectivity?) with important applications in conservation.
Non-invasive population genetics
How should we measure genotyping errors generally associated with analyses of limited DNA quantities?
