💥BREAKING: Birds in a tropical pluvial rainforest of the Chocó have been quietly changing in morphology for 109 years. Some have shrunk, others grown. Tails grew longer, bills grew deeper. Even in forests with continuous cover, climate change may be rewriting evolution in real time.

Où sont passés les phoques à capuchon, sur la banquise qui fond ? par Tiphaine Jeanniard-du-Dot theconversation.com/sur-la-banqu... #ecology #ClimateChange @cebc-chizelab.bsky.social @cnrsecologie.bsky.social @univ-larochelle.fr

My first PhD chapter got published in @nordicoikos.bsky.social! We show that sooty albatross populations are impacted very differently by global changes. 👉 Take a look here: doi.org/10.1002/oik.... @predateursmarins.bsky.social @cebc-chizelab.bsky.social #seabirds #Demography #ecology

With my colleague Christophe Guinet we offer a 6-months position for a master student about sexual selection in southern elephant seals. Here for more details: www.linkedin.com/posts/corali... @predateursmarins.bsky.social @ecophycebc.bsky.social @cebc-chizelab.bsky.social @univ-larochelle.fr

Do I know anyone on here who might find it useful to predict hatching dates from birds eggs? Please reach out if you're open to help me develop ovotime.com to include more species, and to expand with more detailed #oology features! #phenology #seabirds #ornithology 🌍🧪
