New paper today in Proc B @royalsociety.org. We explored nest architecture in 3,685 species of birds, modelling the multivariate nature of nests, i.e. how shape, location or attachment co-occur. Then we explored how the environment affected nest architecture evolution. Spoilers in the title! 🪺🐦🌍

Does anyone know of a nice guide for students (bachelor and master's level) on how to lead group paper discussions that they could share with me? What would be especially great are examples of the types of questions they should ask the group.

New preprint out from the lab, including @rroyaute.bsky.social:

In this we test what we refer to as the "standard model" of behavioral variation.
This was inspired by recent work identifying intra-genotypic variation as a major contributor to "individuality".
