Spatiotemporal patterns of desiccation tolerance in natural populations of Drosophila melanogaster

This study examines desiccation tolerance in Drosophila melanogaster across natural populations and experimental conditions, finding a shallow latitudinal cline and no seasonal or experimental evolution differences in tolerance.

Soft selective sweeps in evolutionary rescue

The paper analyzes evolutionary rescue scenarios, finding that soft selective sweeps, where multiple adaptive mutations spread simultaneously, are common when rescue is likely.

Secondary contact and local adaptation contribute to genome-wide patterns of clinal variation in Drosophila melanogaster

The paper examines clinal variation in Drosophila melanogaster populations across North America and Australia, showing that admixture from European and African lineages contributes to parallel clinal patterns, limiting the identification of loci under local selection.

Quantification of GC-biased gene conversion in the human genome

This paper quantifies GC-biased gene conversion (gBGC) in the human genome using a new method that accounts for polarization errors and spatial heterogeneity, revealing that gBGC is concentrated in recombination hotspots.

Soft selective sweeps in complex demographic scenarios

This study extends the theory of soft selective sweeps to realistic demographic scenarios, showing how population bottlenecks and fluctuating population sizes affect the likelihood of observing soft sweeps.
