Brand new paper in Biological Conservation! With @herverogissart.bsky.social @jean-guillard.bsky.social and others we studied the genetic structure of Arctic charr populations in the Alps. #fishsci www.sciencedirect.com/science/arti...

First PhD paper for @herverogissart.bsky.social! Nice work showing how rapid evolution and plasticity shape phenotypic divergences among arctic charr populations. @royalsocietypublishing.org royalsocietypublishing.org/rspb/article...

🏔️🐟🧬 Excited to share my first PhD publication! We investigated how phenotypic plasticity, rapid selection, and genetic drift contribute to rapid phenotypic divergence in Arctic charr populations isolated for just over a century. Thanks to all my co-authors, collaborators, and reviewers! 😊

Published today in PNAS: www-pnas-org.ezproxy.lib.uconn.edu/doi/10.1073/... Mark Urban, Chris Elphick, and I argue that conservation programs should pay more attention to heritable within population variation, enabling rapid evolutionary response to environmental changes.

Nice and touching personal story by @herverogissart.bsky.social: 'I dropped out of high school. Now, I’m living my dream as a fish scientist' in @science.org www.science.org/content/arti...

Exciting discussions today at #ESEB2025 Our work shows how a century of isolation in contrasting environments can drive rapid divergence in Arctic charr. Thanks to everyone who stopped by my poster!! 🙂 #EvolutionaryBiology #Evolution
