Dioecy in plants: an evolutionary dead end? Insights from a population genomics study in the Silene genus

This study uses population genomics to challenge the evolutionary dead end hypothesis of dioecy in Silene species, finding increased genetic diversity and adaptation potential in dioecious species.

Inference of distribution of fitness effects and proportion of adaptive substitutions from polymorphism data

This paper develops a method to infer the distribution of fitness effects and proportion of adaptive substitutions from polymorphism data alone, showing it provides more reliable estimates than methods relying on divergence data.

Inference under a Wright-Fisher model using an accurate beta approximation

The paper introduces an improved approximation for allele frequency distribution under the Wright-Fisher model, showing better performance in inferring divergence times between populations.

GC-content evolution in bacterial genomes: the biased gene conversion hypothesis expands.

This study shows that GC-Biased Gene Conversion (gBGC) is widespread in bacterial genomes, producing patterns similar to positive selection and affecting gene composition and base substitution patterns.
