Our new paper is out in @jevbio.bsky.social! Body size shapes aggression as well as how strongly individuals influence their opponents and how responsive they are to social interactions. @cdegroot.bsky.social @roriwijnhorst.bsky.social @dingemanselab.bsky.social doi.org/10.1093/jeb/...

Size-mediated differences in social responsiveness (left) and social impact (right). Here, individual i is smaller, more responsive to variation in opponent body size and elicits more aggression from opponents than individual j.

Directly ater the first coffee break today (Tuesday 11:30) @isbe2026.bsky.social I'll present how group size can increase among-individual variation. Come by, if you want to see some cool applied game theory!

Have you heard of the impact-and-responsiveness model? It's a way to quantify individual differences in social interactions. Curious how it works, performs across study designs, and compares to other approaches? Check out our paper (also the first chapter of my PhD) 👇 doi.org/10.1093/jeb/voag013

New method for studying social responsiveness and social impact: both shape the expression of social traits. Ignoring variation in responsiveness can limit understanding of social trait evolution: @roriwijnhorst.bsky.social @cdegroot.bsky.social @dingemanselab.bsky.social doi.org/10.1093/jeb/...

Abstract. Social interactions mediate the phenotypic expression of fitness-relevant traits. The expression of such labile social traits includes three dist

The thesis is in! ☺️ Today, I offically submitted my PhD thesis about fluctuating selection, personality and dietary specialisation. Feeling grateful for the support, collaboration, and inspiration from so many people ♥️🐦. I’ll really miss these little guys, but am excited for what comes next.

Overleaf is down. Does that mean I get the afternoon off?

We are recruiting students interested in a thesis/internship in behavioral ecology to work with us this field season (Apr-July 2025) on breeding great & blue tits. We don't have internal funding, but we are happy to help students within the EU apply for Erasmus+ projects. erasmus-plus.ec.europa.eu

I haven't seen any starter packs made for behavioral ecology yet, so I decided to create one! If you are a behavioral ecologist (any career stage), please reply so I can add you to the list so we can more easily find each other. go.bsky.app/9mAuB6x
