The dynamics of barrier loci recruitment along a continuum of divergence in the context of gene flow

The paper identifies barrier loci across a divergence continuum in pea aphids, showing their clustering in low-recombination regions and enrichment for genes related to host specialization.

Tissue heterogeneity is associated with phenotypic but not genomic diversity in Wolbachia endosymbionts

This study investigates whether tissue heterogeneity in hosts leads to phenotypic but not genomic diversity in Wolbachia endosymbionts, finding that phenotypic plasticity, not genomic variation, drives diversity.

Identification of a sex-determining locus potentially involved in a conflict over sex-ratio

The paper identifies a genomic region containing a gene related to male sexual differentiation in the pill bug Armadillidium vulgare, potentially involved in sex-ratio distortion.

Phylogenetic relatedness rather than aquatic habitat fosters horizontal transfer of transposable elements in animals

The paper analyzes horizontal transfer of transposable elements in 247 animal species, finding that phylogenetic relatedness, not aquatic habitat, strongly influences HTT rates.
