Finally, my paper is out! It shows how bacteria can utilize their CRISPR immunity against transducing phages to turn them into "pollinators". This way bacteria can speed up their own adaptation through recombination by two orders of magnitude compared to mutations, and they do so when starving!

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/...

📣 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 👏 You can now find evoldir here: evoldir.net

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

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!) Sharing is appreciated 🙏 🧵👇 doi.org/10.1093/fems...

PhD-position vacancy in Jan Hrcek's lab lab.hrcek.net, Czech Academy of Sciences: Exploring how rapid evolution in communities allows maintenance of genetic variation and species diversity. @erc.europa.eu 🪰 🧬 🌏 🧪Application deadline: January 7th 2026

With #eseb2025 coming to a close, it is time to start making plans for 2026. Interested in the interface of evolution 🧬 and ecology 🌳? Come to our #ExE conference hosted by @uniexecec.bsky.social in beautiful #Cornwall. Leave your email address at tinyurl.com/EvolxEcol to join our mailing list!

Population Biology Modeling & Theory (PBMT) is a peer-reviewed journal reporting advances in modeling and theory within population biology. Its scope spans demography, ecology, epidemiology, evolutionary biology, population genetics, and phylogenetics. PBMT will be online soon.

Big news: ARIA's Engineering Ecosystem Resilience (EER) opportunity space has begun funding, we're hiring, and we're sharing our (tentative) roadmap.

Interested in a PhD connecting sensory ecology and evolutionary genetics? Applications are now open for a project on the Speciation Genomics of Eye Size Variation in Heliconius Butterflies in our lab at LMU Munich: www.evol.bio.lmu.de/research/mer... Please repost!

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...

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. www.marshall.senate.gov/wp-content/u... 🧵👇

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...

Opportunity! We are looking for new editors - application deadline is Monday 20th January. Positions available: Associate Editors Handling Editor Commissioning Editor Details here: jevbio.net/call-for-edi...

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. go.bsky.app/J7qDY56

I'm building a Starter Pack of Early Career Evolutionary Biologists. It's hard to gather usernames using the search tool. Please add your name to this thread if you want to be added!

Just created a starter pack for ecological forecasting community! 🦋🍃 Please let me know if you want to be added! go.bsky.app/Qk9PfFw

My app for finding 🦋 accounts you may want to follow has had a make-over: it now displays names and bios, and allows adding an "app password" for direct follow buttons in the listing bsky-follow-finder.theo.io

📣Don't miss your chance to apply for these two permanent positions at BioSS! Applications are open until 25th November! #statistics #maths #statsjobs #researchjobs #mathsjobs

hey everyone! i made a list of some useful starter packs (primarily biology/earth sciences with a few bonus things thrown in) to share with friends who have joined bsky in the last week and thought it may be useful for some people here too! 🌍🧪 #SciSky #BioSky docs.google.com/document/d/1...

Please share widely: The 2025 Speciation Gordon Research Conference (March 2-7 2025) is now open for registration to anyone. If you wish to attend, apply here: www.grc.org/speciation-c... Attendees can present posters, and there are a couple open talk slots to be filled from poster abstracts.

incl. (some) population / ecological / evolutionary genetics folks concerned with conservation genetics [ starter pack ]

Just wanted to let folks know that I am still looking to fill this position. I am hoping to start reviewing applications on Monday. Thanks for passing this along to anyone who might be interested.

Genomics, evolution, and more starter pack! Help build community with this starter pack. This list is currently incomplete. Want to be included? Reply and I will remedy that! go.bsky.app/JjvzkWU

November in Austrian Alps: Schneealpe.

Now in press: Local adaptation in 25 distantly-related plant species tends to involve genes with higher pleiotropy rdcu.be/dR0r6 With global adaptation, we found the opposite pattern (reduced pleiotropy), consistent with migration-selection theory www.biorxiv.org/content/10.1...

Two years ago, we initiated a special issue, Eco-evolutionary dynamics in changing environment for @jevbio.bsky.social. It has now been published - the authors contributed a great set of papers: ow.ly/8bXr50Ssp0T; editorial: doi.org/10.1093/jeb/.... Tereza Nekovářová drew the cover art for us. 💙
