The genomic landscape, causes, and consequences of extensive phylogenomic discordance in Old World mice and rats

This study investigates phylogenomic discordance in Old World mice and rats, finding that genetic linkage and selection influence phylogenetic patterns and that assuming a single species tree can lead to errors in detecting positive selection.

Resource competition drives an invasion-replacement event among shrew species on an island

This study shows that an invasive shrew alters its diet in a new environment, increasing dietary overlap with a native species and leading to its decline.

Consequences of coupled barriers to gene flow for the build-up of genomic differentiation

This study shows that coupled barriers to gene flow lead to greater genomic differentiation than single barriers, supporting theoretical predictions about their combined effects.

Phylogeographic structure of the pygmy shrew: revisiting the roles of southern and northern refugia in Europe.

This study revisits the phylogeographic structure of the Eurasian pygmy shrew, identifying southern and northern glacial refugia and post-LGM demographic expansions.

Long-term reciprocal gene flow in wild and domestic geese reveals complex domestication history

This study uses genome-wide markers to infer the timing of European goose domestication and reveals long-term gene flow between wild and domestic geese, including unexpected contributions from Chinese domestic geese.
