How do species differ in their ability to #adapt to environmental change? This study by Lillith Zijmers, Adam Eyre-Walker &co estimates #evolvability from over 170 multicellular species, revealing that #plants exhibit greater adaptive potential than animals. 🧪#AcademicSky plos.io/4vk2TON

Postdoc search update! I am continuing to solicit applications for a postdoc opening in the lab, and probably around the beginning of July I will start selecting applicants to interview. See evoldir ad here: evoldir.net/brian/evoldi... Please RT or whatever!

@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

Really great to see this preprint out! Amazing effort by @camillecornet.bsky.social, and a privilege to have been involved in this one, thanks for beginning me back to butterflies, Camille! 😉 #TEsky #TEworldwide #Genomics #Bioinformatics #Chromosome #Evolution #Butterflies

Minibwa is a hybrid of bwa-mem and minimap2 and the successor of bwa-mem for short-read mapping. ~4X/2.5X as fast as bwa-mem/bwa-mem2 for WGS reads at comparable accuracy. Native support of directional bisulfite-seq. Applicable to long reads. Preprint at arxiv.org/abs/2606.15357

New preprint from the last portion of my PhD! Despite low masked load, we found evidence for strong inbreeding depression in Devils Hole pupfish. The reason? A recessive lethal haplotype that causes a heart defect among developing embryos. www.biorxiv.org/content/10.6...

Now published: journals.plos.org/plosbiology/...

Excited to share our new paper in which we test how competition alters adaptation at a warming range edge @science.org We find that competition can increase adaptation to warming when there is a shared evolutionary response to both biotic and abiotic drivers of selection: tinyurl.com/3j8s9t8b

New from @gvbarroso.bsky.social in our lab: quantifying the relative importance of mutation rate variation and background selection to levels of diversity along the human genome.

Very happy to announce a big new paper from the lab, led by grad students @smishra677.bsky.social and Laia Pomar-Pallarès (in collaboration with @roblanfear.bsky.social). We introduce a new way to study introgression, with accompanying software (DAFT) 1/n 🧵 www.biorxiv.org/content/10.6...
