So happy to share that my last PhD chapter is finally out in Proc. B! We looked at chacma baboon offspring interference in grooming sessions between their mom and siblings, and asked whether these behaviours could represent jealous reactions.

Not all sexual swellings signal fertility. Some signal strategy. In our new Current Biology paper, we show how gelada females “fake it” during male takeovers—and why it works.

New paper!
We propose a framework to empirically study animal social relationships by modelling social network (SN) data as time-series—that is, without the need to aggregate them over time.

Wild female gorillas live long after their last baby is born.
Do they go through menopause?

super cool study found human artifacts in Bearded vulture nests, incl.

Age- and sex-dependent associations between the number of older siblings and early-life survival in pre-industrial humans | Proceedings of the Royal Society B: Biological Sciences
Siblings are an important part of an individual’s early-life environment and may therefore play an important role in shaping an individual’s survival. The quantification of sibling effects on survival is challenging, however, especially in long-lived ...
