Hi! (evolutionary) theoretical ecologists here, particularly concerned with evolution of species' ranges - if you still have space.

Delighted to present our Macrogenetics atlas of prokaryotes. www.biorxiv.org/content/10.1... This is a herculean effort from Chao Yang, which has a previous existence as a preprint first posted in 2018 "why panmictic bacteria are rare?" www.biorxiv.org/content/10.1...

Macrogenetic atlas of prokaryotes

Macrogenetics investigates the patterns and predictors of intraspecific genetic variation across diverse taxa, offering a framework to address longstanding evolutionary hypotheses. Here, we present a ...

It is worth paying close attention to the new bill "Dangerous Viral Gain of Function Research Moratorium Act" introduced by Senator Roger Marshall.

If enacted, it will effectively stop all of virological research, including for vaccines.

You are right! Incidentally, I am just trying to put together a sentence to at least refer to some of the ENM works which I came across (www.pnas.org/doi/full/10....). I take that ENM work comes from ecology, whereas this comes from evolution: coupling evolutionary genetics with population dynamics.

Thanks! Looking forward to questions/comments. Submitting at some point next week..

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...

Excited to share our new study in @ismepublications.bsky.social showing that microbial niche breadth specialisation (being a generalist or a specialist) impacts ecological and evolutionary adaptation following environmental change doi.org/10.1093/isme...

Niche breadth specialization impacts ecological and evolutionary adaptation following environmental change

Abstract. Ecological theory predicts that organismal distribution and abundance depend on the ability to adapt to environmental change. It also predicts th

A really lovely perspective on our paper led by @grantkinsler.bsky.social and Yuping Li in Plos Biology! journals.plos.org/plosbiology/...

Regulatory networks may evolve to favor adaptive foresight

Pleiotropy (a single mutation altering many traits) has long been seen as hindering adaptation. A new study in PLOS Biology offers a striking counterexample, suggesting that regulatory networks may ev...

If you have space, I am interested in species cohesion as much as in speciation; particularly in spatially structured environments.

I made a starter pack of speciation researchers. Please let me know if you or someone you know would like to be added. I am particularly sad that so far there are not many speciation researchers from the Global South represented.

I work on models of joint evolutionary (population genetic) and ecological (population) dynamics in spatially and temporally variable environments. If it fits, I'd love to be added too.

Jitka Polechová @polejit.bsky.social · Nov 18

The above paper is a classic, well worth a read. Recently, Nick Barton (2024) wrote a detailed overview of the theory of limits to adaptation, focusing on feedback between evolutionary (population genetic) and demographic dynamics, as well as insights from information theory: doi.org/10.1093/jeb/...

One near-tautology well articulated by Janis Antonovics in The nature of limits to natural selection (1976): "Insufficient genetic variability and the swamping effects of gene flow are inadequate [later: "almost tautological"] explanations of limits to natural selection." doi.org/10.2307/2395...
