The impact of social complexity on the efficacy of natural selection in termites

This study examines how social complexity in termites affects natural selection efficiency by analyzing dN/dS ratios across Blattodea species and termite transcriptomes.

Detection of F1 hybrids from single-genome data reveals frequent hybridization in Hymenoptera and particularly ants

The paper develops a method to detect F1 hybrids from single-genome data and applies it to arthropods, finding high hybridization rates in Hymenoptera, especially ants.

Hybridization enables the fixation of selfish queen genotypes in eusocial colonies

This study uses mathematical modeling to show hybridization can drive evolutionary arms races in eusocial colonies, leading to genetically hard-wired caste determination.

DILS : Demographic Inferences with Linked Selection by using ABC

DILS performs demographic inferences with linked selection using ABC on population genomic data, identifying models and loci associated with gene flow and population size changes.

Relaxation of purifying selection suggests low effective population size in eusocial Hymenoptera and solitary pollinating bees

The paper investigates the impact of eusociality and pollination on effective population size and purifying selection in Hymenoptera, finding relaxed selection in both social and non-social bees.

Evolutionary history of the porpoises (Phocoenidae) across the speciation continuum: a mitogenome phylogeographic perspective

This study reconstructs the evolutionary history of porpoises using mitochondrial genomes, revealing patterns shaped by Quaternary Glaciations and highlighting conservation implications.

MitoFinder: efficient automated large-scale extraction of mitogenomic data in target enrichment phylogenomics

MitoFinder extracts mitogenomic data from UCE libraries, increasing ant mitogenome availability by tenfold using metagenomic assemblers.

The divergence history of European blue mussel species reconstructed from Approximate Bayesian Computation: the effects of sequencing techniques and sampling strategies

This study uses Approximate Bayesian Computation to reconstruct the divergence history of European blue mussels, showing that binning strategies in site frequency spectra significantly affect results and that complex gene flow models are preferred.

Codon usage bias in animals: disentangling the effects of natural selection, effective population size and GC-biased gene conversion

This study investigates codon usage bias in 31 non-model animal species, finding translational selection in large-Ne species and GC-biased gene conversion as a dominant force across all species.
