Although range expansions have occurred recurrently in the history of most species, their
genetic consequences have been little investigated. Theoretical studies show that range …

Density-dependent processes play a key role in the spatial structuring of biodiversity.
Specifically, interrelated demographic processes, such as gene surfing, high-density …

Patterns of genetic diversity between populations are often used to detect loci under
selection in genome scans. Indeed, loci involved in local adaptations should show high F ST …

Niche construction is the process by which organisms construct important components of
their local environment in ways that introduce novel selection pressures. Lactase …

Genomic scans of multiple populations often reveal marker loci with greatly increased
differentiation between populations. Often this differentiation coincides in space with …

Over the past two decades, microsatellite genotypes have provided the data for landmark
studies of human population-genetic variation. However, the various microsatellite data sets …

Expanding populations incur a mutation burden, the so-called expansion load. Using a
mixture of individual-based simulations and analytical modeling, we study the expansion …

Range expansions are extremely common, but have only recently begun to attract attention
in terms of their genetic consequences. As populations expand, demes at the wave front …

We propose a method that uses genetic data to test for the occurrence of a recent range
expansion and to infer the location of the origin of the expansion. We introduce a statistic ψ …

Empowered by technology and sampling efforts designed to facilitate genome-wide
association mapping, human geneticists are now studying the geography of genetic …
