I invite applications for a PhD position. Join our team exploring how rapid evolution in communities allows maintenance of genetic variation and species diversity! Application deadline is 7th May 2026. See lab.hrcek.net
📣 EvolDir is now managed by @eseb.bsky.social!
We are delighted to be taking the reins and express our gratitude to both Brian Golding who began this service to the community in the mid-1980s and to @rdmpage.bsky.social who ran this account until now 👏

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
Lovely article about the impactful and inspirational career of Roger Butlin (now retired). I've always admired how he worked hard at community building and research synthesis, and his research achievements were even more extensive than I realised: doi.org/10.1093/jeb/...
Abstract. Habitat loss contributes to extinction risk in multiple ways. Genetically, small populations can face an ‘extinction vortex’—a positive feedback
In 2025, the annual meeting of the Population Genetics Group (PopGroup) returned to Sheffield, U.K., for the third time. The timing could not have been mor
I'm hiring a postdoc to lead sedimentary aDNA reconstructions of alpine plant biodiversity as part of a broader project exploring the mechanisms of alpine plant resilience. Come join a collaborative team working in beautiful places! Bonus: postdocs at UMaine are unionized!

The study shows that adaptation to changing environments is subject to a critical limit: even when environmental change is gradual, there is a tipping point beyond which adaptation can suddenly fail. ...
In case you missed it: our review titled "Spatial structure: shaping the ecology and evolution of microbial communities" is out! 🚨
Let me hit you with some highlights on why spatial structure matters. (and why you should care!)

New #ecoevo paper @pnas.org: Evolution of species’ range and niche in changing environments. I show that feedback between evolutionary and population dynamics can create a tipping point where genetic variance erodes, and species’ ranges contract or fragment www.pnas.org/doi/10.1073/... #popgen 🧬🧪 🌎

Preprint finally out! I show that eco-evo feedback can drive a tipping point where genetic drift overwhelms adaptation. This can result in a contraction of a species' range border or range fragmentation. Fragmentation is abrupt and arises readily under rapid temporal change. doi.org/10.1101/2025...
