💥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 ?
Que se passe-t-il quand l’espèce animale qu’on étudie commence à disparaître ? Certains biologistes marins, qui étudient le phoque à capuchon, doivent aujourd’hui se poser la question.

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 🌍🧪

New paper:
contrasting Adélie penguin foraging behaviour during years of high and low krill availability

@cebc-chizelab.bsky.social @cnrsecologie.bsky.social @univ-larochelle.fr @cnrsaquitaine.bsky.social
Comparative drawing of penguins diving under high or low krill availability. Under high krill availability we can see that the penguins dive less deep, for shorter bouts, and with less distance and duration between bouts. The prey capture within bouts remains constant under high and low krill availability though.

Comparison of adaptation rates based on the six definitions (Equations (3-5)). Each panel presents a different definition. The rate of adaptation can be indicated per unit of time or generation, and either without standardization for the strength of selection, with standardization at the level of the vital rate, or with standardization at the level of total fitness.

#WithoutNSF #SaveNSF #SupportNSF
SSE, SSB, and ASN logos. Text: Tri-societies Week of Action for NSF. Science under siege: Over 1000 NSF grants have been terminated by political appointees- threatening the foundation of American innovation and education, and more cuts loom; entire research programs are being erased without explanation. What’s at stake? STEM education for K-12 students, jobs and infrastructure in rural communities, support for veterans in research and education, cybersecurity and national defense innovation, global leadership in science and technology. Join the week of action: Contact Congress: Switchboard: (202) 224-3121, tell them to protect NSF. Share your story: Post on social media #WithoutNSF #SupportNSF #SaveNSF, engage local media; use our media tool to reach out to local reporters and newspapers; engage others: communicate the importance of NSF to colleagues, friends, and family.
