This has been a fantastic course, very well done @valentinapeona.bsky.social and @ritarebollo.bsky.social ! 🙌
Looking forward to continue diving into the field 😊

3/9 The black-or-white throat polymorphism is explained by the interaction of a transposable element (an LTR retrotransposon) upstream ASIP with ASIP coding variation. Mantle and neck side coloration is encoded by additive effects of regulatory variants upstream ASIP.

How does genetic architecture constrain evolutionary trajectories? To address this question, we inferred the genetic architecture of convergent plumage coloration and its evolutionary history in wheatears.

A mosaic of modular variation at a single gene underpins convergent plumage coloration
The reshuffling of genomic variation from multiple origins is an important contributor to phenotypic diversification, yet insights into the evolutionary trajectories of this combinatorial process and ...

I am also deeply nostalgic as it was the last project with my friend and colleague, Daniele Di Marino, who sadly passed away last year. Missing a lot his energy in scientific research!

Awesome paper where conservation biology goes wild into genomics, experimental cell biology and biophysics!! Amazing job @emitruc.bsky.social and team 🐻
Happy to share the latest publication from our labs on the Apennine brown bear, a relict population not far from Rome, Italy. www.pnas.org/doi/10.1073/pnas.2504409122
Thanks to great co-auths, we moved beyond our "genomic" comfort zone incl. cellular experiments and molecular dynamics simulations.
