Molecular Evolution of a Sex-Linked Inversion Polymorphism in Zebra Finches

Abstract. Recent years have seen an explosion in examples of supergenes, where recombination is suppressed between haplotypes, often via inversion polymorp

@teganhoran.bsky.social et al. challenge the prevailing view that synaptonemal complex length is the primary determinant of sexually dimorphic crossover rates. 🔗 doi.org/10.1093/molbev/msag130 #evobio #molbio

Molecular assessment of recombination processing across genetically diverse mouse strains reveals sexually dimorphic determinants of crossover distribution beyond chromosome length

Abstract. Meiotic recombination generates crossovers (COs), reciprocal exchanges between homologous chromosomes critical for accurate chromosome segregatio

A mouse that lives higher than any other mammal has evolved unexpected adaptations that allow it to thrive from sea level to Andean summits, researchers report in a new Science study. Learn more: https://scim.ag/4bzjqWY

Adaptation across an extreme elevational gradient in Andean leaf-eared mice, the world’s highest-dwelling mammal

Andean leaf-eared mice (Phyllotis vaccarum) live at the highest elevations of any mammal, and they also have the broadest elevational range, from sea level to mountain summits of >6700 meters. Highlan...

🌏 SMBE is calling for proposals for SATELLITE/INTERDISCIPLINARY/REGIONAL SMBE meetings for the period January-December 2027. The deadline for submission of proposals is August 31, 2026. Decisions will be communicated to the applicants by the end of September 2026. #society

Researchers in #EvolutionaryBiology & #Ecology wanting to do the right thing? @nicolasgaltier.bsky.social at #SMBE2026 talking about DAFNEE, a database of >600 #ecoevo #evoeco academia-friendly journals for "responsible publishing" - @plos.org seems to do OK here...!

Just one more talk, please? ☝️ #SMBE2026 in Copenhagen concludes. It's been an amazing week - with the largest ever attendance at an SMBE meeting! #society

Save the date for the 2027 SMBE Conference in Québec City! The LOC of #SMBE2027 would like to welcome you to Québec City for the 2027 Conference of the Society for Molecular Biology and Evolution,from June 20-24, 2027, and hosted by Université Laval at the Québec Convention Centre. #society

Diego Cortez on the weird Y chromosomes of lizards: a ribosomal protein is the sex determining factor (!) #SMBE2026 also, excellent thank you slide.

If there's a prize for the best poster title at #SMBE2026, this gets my vote:

Excellent and super interesting talk by @aruizherrera.bsky.social to kick off #meoiticrecombination symposium 🧬👏👉 #smbe2026 #recombination #3Dchromatian #crossover

Tomorrow I will be giving a talk at #SMBE2026 in the Main Hall at 11:25-11:30 about "Rapid chromosome evolution in Panagrolaimus nematodes"

So let’s get it started: #SexChromosomes evolution 🧬😄 #smbe2026 @aruizherrera.bsky.social @official-smbe.bsky.social

Yesterday I presented what I think was the first conference poster of my career 😅 at #SMBE2026, talking about my ERC StG project on the genomics of miniaturisation in vertebrates—GEMINI. Really happy for the discussions it sparked. Thanks everyone who stopped by! 🧪

Great talk @arthurmatte.bsky.social #SMBE2026 on the evolution of sperm. If you are interested the preprint is here: doi.org/10.1101/2025...
