Our paper on genetic load in an invasive guppy population is now published in @genomeresearch.bsky.social It was a fantastic journey — from field sampling to analysis and finally publication. I hope readers will enjoy the story as much as we enjoyed working on it. genome.cshlp.org/content/36/7...

@sebchm.bsky.social et al. study bulb mites to show that sex ratio manipulation drives evolution of male harm to females and widespread haplotype frequency changes without clear evidence for enhanced purging or maintenance of genetic diversity. 🔗 doi.org/10.1093/gbe/evag151 #societyjournal

Just arrived in Copenhagen for #SMBE2026. The weather is hot, but the Royal Library is calm, (relatively) cool, and free to enter. A perfect spot to escape the heat for a while. Highly recommended!

Interested in the evolutionary genomics of host-pathogen interactions or the evolutionary ecology of senescence? 1 week left to apply for the two postdoc positions in our badger - bovine TB project🦡🦠🧪🧬👇

Still some time to apply to our postdoc position - deadline 3rd July. I'll be at #SMBE2026 if anyone would like to chat about it 😊

Our traditional Evokayak retreat is sadly over. Some of us absorbed inspiring talks horizontally and survived kayak teamwork vertically. Great to see friends from Kraków and Łódź. Thanks for coming and see you in two years!

I've been keeping this quiet for a while, but now's as good a time as any to announce: I have a book contract for a new textbook, Applied Evolutionary Medicine, with Princeton Univ Press. Core theme: "What, if anything, do medical practitioners do differently when they understand evolution"?

Our new paper doi.org/10.1098/rspb... on long-term genetic threats to small populations finds that "mutational meltdown" (bad mutations fixing) is less of a problem than "mutational drought" (too few good new mutations) @wmawass.bsky.social @uliseshmc.bsky.social @jeremyjberg.bsky.social 1/5

As a PhD student, I was part of a unique long-term selection experiment in bank voles. Then Puumala hantavirus hit. Thanks to deep biological insight, courage & huge effort, the virus was eradicated—and the experiment survived. Now, details of this story can be found here: doi.org/10.1371/jour...

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.
