"Some genetic consequences of population and social structure" : Présentation travaux

Résumé:

Most species are spatially and socially organised. However, population geneticists tend to ignore both facts and typically use demographic models that assume random mating over wide geographical areas (i.e. they ignore population structure) or over more limited/local areas (i.e. they ignore social structure). This is sometimes surprising given that structured models, such as the n-island (Wright, 1931) or the stepping-stone (Kimura, 1953) models were actually devised more than sixty years ago.

Given that genetic data are increasingly used for the conservation of endangered species including lemurs and given that genetic data provide unique information on the recent evolution of populations (population expansions or contractions, time of population split, admixture, etc.), it is important to understand how population and social structure should be integrated to help understand the genetics of endangered species. I will present some recent results obtained in our group in Madagascar.
