For those at #ECS2025, don't miss @wild-devs.bsky.social talk on reproductive hormones in fin whales and Alexandra's talk on proteomics in pilot whales this morning.

Delighted to say that both Alexandra Tranganida and @wild-devs.bsky.social will be presenting at the European Cetacean Society conference next week! Alexandra will talk about blubber proteomics in pilot whales and Devonne about reproductive hormones in fin whales (Day 2 - session 6). #ECS2025

Extremely proud of @wild-devs.bsky.social first first-author publication. Devonne showed sexual segregation and stable pregnancy rates in minke whales sampled in the Gulf of St. Lawrence between 2007-2015 @jlkershaw.bsky.social @leverhulme.ac.uk @meps-ir.bsky.social

Cognitive perception of circulating oxygen in seals is the reason they don’t drown Marine mammals rely on maintaining sufficient blood oxygen levels while diving to prevent drowning. Generally, oxygen is cognitively imperceptible to mammals that instead sense rising carbon dioxide a...

Incredible new Science paper by @chrismcknight.bsky.social, @jlkershaw.bsky.social and team that shows seals do cognitively perceive circulating oxygen and alter their diving behaviour accordingly www.science.org/doi/10.1126/...

Always great to catch up with @strandings.bsky.social and all set for a great day!!

What an incredible inspirational talk by @mdelibeg.bsky.social, the new Regius Chair in Physiology. Great night socialising with people of the medical campus.
