Rapid establishment of species barriers in plants compared to animals

F. Monnet, Z. Postel, P. Touzet, C. Fraisse, Y. Van de Peer, X. Vekemans, C. Roux

The paper finds that genetic exchange is more frequent between animal species than plant species at the same level of genetic divergence, suggesting faster establishment of species barriers in plants.

Holocene climate change promoted allopatric divergence and disjunct geographic distribution in a bee orchid species

A. Gibert, R. Buscail, M. Baguette, C. Fraisse, C. Roux, B. Schatz, J. A. M. Bertrand

This study uses population genomics and ecological niche modeling to show recent allopatric divergence and climate-driven range shifts in the bee orchid Ophrys aveyronensis.

Introgression between highly divergent sea squirt genomes: an adaptive breakthrough?

C. Fraisse, A. Le Moan, C. Roux, G. Dubois, C. Daguin-Thiebaut, P.-A. Gagnaire, F. Viard, N. Bierne

The paper examines introgression between Ciona intestinalis and Ciona robusta in the English Channel, finding a hotspot of recent introgression linked to a cytochrome P450 gene.

An introgression breakthrough left by an anthropogenic contact between two ascidians

A. Le Moan, C. Roby, C. Fraisse, C. Daguin-Thiebaut, N. Bierne, F. Viard

The paper investigates hybridization between Ciona species, finding recent introgression of C. robusta into C. intestinalis genomes after human-driven introduction.

DILS : Demographic Inferences with Linked Selection by using ABC

C. Fraisse, I. Popovic, C. Mazoyer, B. Spataro, S. Delmotte, J. Romiguier, E. Loire, A. Simon, N. Galtier, L. Duret, N. Bierne, X. Vekemans, C. Roux

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.

The rates of introgression and barriers to genetic exchange between hybridizing species: sex chromosomes vs. autosomes

C. Fraisse, H. Sachdeva

The paper quantitatively evaluates how sex chromosomes and autosomes act as barriers to genetic exchange between hybridizing species, showing sex chromosomes reduce introgression due to hemizygosity and reduced recombination.

The distribution of epistasis on simple fitness landscapes

C. Fraisse, J. J. Welch

The paper analyzes epistasis in yeast snoRNA mutant data using simple fitness landscape models, finding that epistasis has limited impact on evolutionary dynamics.

Fine-grained habitat-associated genetic connectivity in an admixed population of mussels in the small isolated Kerguelen Islands

C. Fraisse, A. Haguenauer, K. Gerard, A. A.-T. Weber, N. Bierne, A. Chenuil

The paper investigates genetic connectivity and admixture in Kerguelen mussels, finding that environmental factors better explain population structure than geographic distance.

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

C. Fraisse, C. Roux, P.-A. Gagnaire, J. Romiguier, N. Faivre, J. J. Welch, N. Bierne

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.
