New preprint just online, led by Fay Frost and me: comparing the thermal sensitivity of 300+ invertebrate life history traits shows that reproduction is more sensitive than lifespan to warming. Studies focusing on survival may be underestimating the effect of warming on animal populations 🔥🔥🔥

Question: do I know anyone near Nantes who would be willing to pick up a dead gull-billed tern and its logger? L49 has sadly been killed near a road. I’d be very grateful for a picture and the logger and would of course reimburse postage.

New pre-print led by the amazing @patricepottier.bsky.social - very little evidence for evolution of life history traits in response to warming, even in insects. Rapid adaptation is unlikely to mitigate the continuing impacts of climate change 🔥🔥🔥
