@kokkonut.bsky.social
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.)
A while ago @caritalindstedt.bsky.social asked me “would you puke to save the group?” Well not me personally, there's real science about the evolution of cooperation here. With the help of talented student @abhay-gupta.bsky.social, we now have answers! royalsocietypublishing.org/doi/epdf/10....
Sex-biased cooperation among immature peers: it matters who helps whom

Hmm. Preparing to post about a group member's nice new paper on the evolution of cooperation (out in a couple of days time), I feel regret we did not include the presence of Batman in any of the model versions.
As someone studying unexpected events of all kinds, this was a funny (and unexpected) paper to randomly stumble upon: the presence of a man in a batman costume on a train makes passengers significantly more likely to stand up for a pregnant woman: www.nature.com/articles/s44... Good to know I guess.

For a while (many years!) back, @eseb.bsky.social gave us €€€ to form a Special Topic Network. Formally, the network no longer exists, but informally for sure AND we can now pick the fruits of our labours! Here is one and the next post shows another... Thank you ESEB! 🙏

Molecular and genomic insights to sexually antagonistic genes

Application deadline: Dec 2, 2025

Molecular and genomic insights to sexually antagonistic genes (GRIESHOP_U26DTP) | Doctoral Training Partnership
Why do harmful genes persist in populations instead of being removed by natural selection? One answer lies in sexual antagonism: when a genetic variant benefits males but harms females, or vice versa.

What is sexual selection all about... definitionally and mathematically? A super talented PI, Jussi Lehtonen, is looking for a postdoc to work it all out! Deadline end of this month.

@romanzug.bsky.social and @socialinsectlab.bsky.social thinking about colony dynamics! Resource variation can mask tradeoffs, but here we show that even if that *doesn't* vary, lucky starts in colony life can lead to better trajectories and if so, a tradeoff is often undetectable despite being real.
