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

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.

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.

The paper bridges evolutionary graph theory and experimental conditions by introducing a new model of spatially structured populations and analyzing recent experiments to test predictions about mutant fixation.
