Congratulations to @jeffgroh.bsky.social on the publication of his paper on an ancient balanced polymorphisms controlling heterodichogamy in two genera of wingnuts. The paper shows the putative turnover & reversal of dominance of a mating type polymorphism www.sciencedirect.com/science/arti...

1/9 New in @science.org www.science.org/doi/10.1126/science.ado8005 How does genetic architecture constrain evolutionary trajectories? To address this question, we inferred the genetic architecture of convergent plumage coloration and its evolutionary history in wheatears.

Interplay between purging and admixture shapes genetic load in an invasive guppy population https://www.biorxiv.org/content/10.1101/2025.09.12.675788v1

Our latest preprint shows that in translocated invasive guppy population, genetic load is reshaped by purging and admixture. A bottleneck purged strongly deleterious mutations, but admixture reversed this effect while reducing the load of weakly deleterious mutations. www.biorxiv.org/content/10.1...

How do populations maintain an evolutionary memory? I am happy to share that our work with Dmitri Petrov @petrovadmitri.bsky.social, Paul Schmidt, and colleagues on dominance reversal and stabilization of insecticide resistance in changing environments over time is now published at Nature EE.

Fighting to persist: Genetic rescue increases long-term fitness despite elevated genetic load https://www.biorxiv.org/content/10.1101/2025.09.06.673525v1

Check out our latest work! We experimentally showed that #genetic #rescue works: in the bulb mites, boosting genome-wide variation improved survival for 20 generations in high temp. Elevated genetic load or sexually selected traits? Barely mattered. #Conservation www.biorxiv.org/content/10.1...

@neelamporwal.bsky.social ‘s talk about estimating extinction risks under sexual selection using simulations, at PEC2025 won the first prize for the best student talk. So, should animals swipe right for survival?🐧

Small update: Plenaries and Nosil talks: "Nature/Science" in the bottom right of a slide #eseb2025

We are having fantastic time presenting and discussing our work at #ESEB2025 - Neelam Porwal answered a question "How sexual selection shapes small populations demography under recurrent heatwaves"

#eseb2025 talks were great so far. Subjective ranking of the most common quotes: - theory and modeling: "with this very simple approach" - genomics: "using methodology you all know" - plenaries: "Nature/Science" in the bottom right of a slide - posters: "una cerveza por favor"

Stuart et al. show footprints of selection after near-extinction: genetics of wild and captive Lord Howe stick insect show that after a severe bottleneck, inbreeding appears to remove harmful mutations via increased homozygosity. 🔗 doi.org/10.1093/molb... #selection #evobio #molbio

Here we come! A shiny profile of our group is on. Exciting news are coming soon

Excited about these new results on a butterfly-plant arms race where one butterfly has overcome a physical plant defence - hooked trichomes- with a combination of external and internal adaptations. Well done @ritabrata1907.bsky.social
