A.v.Humboldt professor at the University of Mainz. Evolutionary ecologist. Runs a research group that once prompted the description "in this [coffee] room there's almost always someone who is at least partially fun". (Which we then translated into Latin.)
I work at a public library. People who want to use AI seem to have no trouble doing so. People who don't want to use AI have a harder time. I crowdsourced and then finalized this document "How to disable or avoid intrusive AI" and then gave it a short URL: notoai.org Please pass along if it's useful
.The very talented and fun Jonathan Henshaw has two positions to offer! If you like theoretical eco-evo questions, don't hesitate. Also, Freiburg is a very pretty place PhD: uni-freiburg.de/stellenangeb... Postdoc: uni-freiburg.de/stellenangeb...

wanna read the latest overview of “internal evolutionary conflicts” — scenarios where genes spread despite being organism-deleterious? and wanna learn how to model them? look at our new preprint! we introduce unifying ideas, and try hard to write accessibly. small 🧵 www.biorxiv.org/content/10.6...

I compiled a list of 350 #funding opportunities for #postdoctoral research #fellowships: https://docs.google.com/spreadsheets/d/1J2M_tQgoqV4ivpfEClh9qs9f2KQN2O1G3Jpda2aoHfQ/edit?usp=sharing I realized I should share this again after mentioning it to some folks at the #EFP2026
A new group dedicated to evolutionary ecology! This is an opportunity to have a permanent community space for the field, as well as ensure regular conferences like #ExE2026. But it needs your help 👇
We’re now looking for evolutionary ecologists to join our committee to build #ExE2026 into the start of something great, not just a one-off. Details here: www.britishecologicalsociety.org/content/evol...
I've been to a lot of meetings where the timekeeping signals are bird calls, but it's special when the meeting's outing goes to that place where you can see & hear the birds! The scenery was OK too. #ExE2026
Check out this really interesting preprint by @shikharabhat.bsky.social and @kokkonut.bsky.social on models of senescence and their connection to models of multilevel selection. It seems like these fun jump processes, PDEs, and SPDEs arise in a variety of biological contexts.
If you like multi-level selection, you may enjoy (models of) ageing. @kokkonut.bsky.social and I show that the mortality patterns generated by dem. senescence are formally equivalent to a multi-level selection process! arxiv.org/abs/2607.00262 Confused? So were we! A short explainer thread below
@crab-exeter.bsky.social are a fantastic group of researchers, and a real beacon of excellence for Exeter. What a huge and deeply sad act of self sabotage this would be. Please consider signing their open letter👇🏻

Springer Nature retracted two studies by Max Planck. In response to a question from @samkean.bsky.social, they issued this statement: "Detailed information about specific retractions is usually confidential and can only be shared with the relevant authors.”

Polymorphisms are fun to study, here is a butterfly one. Negative freq.dependence works to maintain things but where does it come from? Temporal variation works but not always! @koraklein.bsky.social and @chriswheat.bsky.social looked into this in detail. royalsocietypublishing.org/rstb/article...
Emergence time difference can create negative frequency dependence and maintain a colour polymorphism in Colias butterflies
Abstract. Many species of Colias butterflies show a female-limited colour polymorphism where the dominant Alba allele leads to white wings, faster developm

Really excited to share that one part of my PhD research is now publicly accessible on preprint servers! Here is a thread explaining our (@kokkonut.bsky.social and I) work on ageing and stochastic damage/failure accumulation, available as a preprint at www.biorxiv.org/content/10.6...

I title this arty photo "Dedication"! @ccrowther.bsky.social did great at Pint of Science last night: how long should you wait for your mate to return from migration before concluding "screw this, likely dead"? - Bummed you missed it? Come to @isbe2026.bsky.social or inspect a poster at #ExE2026.
I still love the theory a Year 6 child proposed to me that David Attenborough is actually God and he got fed up with people not noticing the amazing things he'd created, so he made documentaries to show off.
Big opportunities for researchers 🌍 We are investing nearly €400 million to help researchers share their work and collaborate with the best scientific teams across the EU. The 2026 Marie Skłodowska-Curie Actions Postdoctoral Fellowships are now open. More: link.europa.eu/PNxpxw

New masters programme in Evolutionary Anthropology - University of Leipzig & Max Planck Institute for Evolutionary Anthropology, teaching in English www.uni-leipzig.de/en/studying/... #EHBEA
Evolutionary Anthropology MSc
The programme aims to provide in-depth knowledge of the latest research into human evolution and development. The focus is on the genetic, paleoanthropological and cognitive aspects of human behaviour and the mind. Particular emphasis is placed on engaging with the complexities of research processes, and on developing skills in designing, implementing and evaluating studies. Students will gain professional expertise in handling and rigorously analysing and effectively presenting data, preparing them for doctoral research.
