Is male aggression good or bad for populations under heatwaves? Find out in our recently published article onlinelibrary.wiley.com/doi/full/10....

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...
Interplay between purging and admixture shapes genetic load in an invasive guppy population
Demographic history can shape the genetic load of populations by influencing the efficacy of selection, levels of heterozygosity, and by incorporation of new variants via gene flow. Understanding thes...

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

@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?🐧

It's that time of year when we spend our days in the woods. The forests are silent, yet inhabited by rodents and ticks.

Not only fantastic #ESEB2025 talks, but also great posters. Józefina presented her work on Borelia, Neha on sexual selection and populations dynamics, Sebastian on bulb mite genomics, Mateusz on genetic load in guppies and Jacek on CFH gene in bank voles. Our diversity unleashed!

Jon Parrett explained whether sexually selected traits can influence the efficacy of genetic rescue

Jacek Radwan advocated towards an open and responsible publication model

We are having fantastic time presenting and discussing our work at #ESEB2025

Gratulacje!
@k-burda.bsky.social for defending her PhD titled “Determinants of genetic load in natural populations of guppies”
She estimated per-generation mutation rate in guppies and explored how demographic events affect the buildup or removal of harmful variation in their natural populations.

We explore evolution’s thrilling battles, between and within sexes and, hosts vs. parasites. Our focus? Conservation genomics, experimental evolution, adaptation, and mutation dynamics, with special attention to sexual selection 🦌 in mites and host-pathogen coevolution in Borrelia and bank voles 🐀.
