Promotion of cooperation in deme-structured populations with growth-merging dynamics

This study shows that cooperation is promoted in deme-structured populations under growth-merging dynamics with hard selection, but not under soft selection.

Environment heterogeneity creates fast amplifiers of natural selection in graph-structured populations

The paper shows environment heterogeneity can amplify natural selection and speed up mutant fixation in graph-structured populations, depending on migration rates and mutant fitness advantages.

Impact of phylogeny on the inference of functional sectors from protein sequence data

The paper evaluates how phylogeny affects the identification of functional sectors in protein sequences and shows that two methods, conservation and ICOD, are robust to phylogeny and provide complementary insights.
