Nonstationary patterns of isolation-by-distance: inferring measures of local genetic differentiation with Bayesian kriging.

Abstract excerpt

Patterns of isolation-by-distance (IBD) arise when population differentiation increases with increasing geographic distances. Patterns of IBD are usually caused by local spatial dispersal, which explains why differences of allele frequencies between populations accumulate with distance. However, spatial variations of demographic parameters such as migration rate or population density can generate nonstationary...
