Studying social transmission using STbayes Post provided by Michael Chimento. When studying animal culture, it’s important to establish whether novel behaviours or information have spread through social contact, or are rather innovated or p…

I am looking for a PhD student to join my new Socio-Eco-Evo group, hosted in Katie Peichel's Evolutionary Ecology Division @ University of Bern. We're offering a fully funded 4-year position, studying social plasticity and behavioral adaptation among stickleback in Greenland. Please share around!

Very happy to see our ice-fishing paper on the cover of @science.org this week! πŸŽ£πŸŽ‰

We tracked large groups of Finnish competitive ice-fishers to study how social foragers use social information when searching for resources. 🐟

✨New paper✨
How do juvenile ravens find social groups?

We describe how juvenile common ravens, who have left their natal territories seeking to join non-breeder flocks, use space with respect to other birds, and discuss what this means for social integration.

Our paper is published today in Current Biology and is featured on the cover!

We report a neat, and somewhat counter-intuitive, finding: higher-ranking baboons get less and more interrupted night-time rest.
