The final chapter of my PhD is published in Journal of Experimental Biology! And, we got the cover! We used biologgers to estimate great hammerheads' temperature “sweet spot.” We saw they can perform well at a range of temps, which supports observations from the field. (1/2) 🌊🦑🧪🐟

New paper out today! Using accelerometers to generate thermal performance curves in great hammerhead sharks. Their low activation energies may explain why they can perform well across seasons.

New paper introducing the term of SUPER HABITAT for sharks in which all critical activities (resting, feeding, mating & giving birth) occurs. 🦈🌴❤️🍽️ 👶 Access the paper here: www.sciencedirect.com/science/arti... @dr-yannis.bsky.social @charlie-huveneers.bsky.social

‼️ New important shark paper 🦈 We demonstrate that all critical life stages (resting, feeding, being cleaned, mating & giving birth) can occur in the small Fakarava channel & we define it as a “super habitat” www.sciencedirect.com/science/arti... @dr-yannis.bsky.social @charlie-huveneers.bsky.social

Further coverage, this time from National Geographic, of new paper by @dr-yannis.bsky.social discussing #electricrays using their shocks to avoid getting eaten by large sharks www.nationalgeographic.com/animals/arti...
nationalgeographic.com
This animal has a built-in taser to stun sharks
Electric rays are staying out of the stomachs of sharks by shocking them—with up to 200 volts.

New paper lead by @etspencer.bsky.social We use biologging to understand why great hammerheads may specialize on large prey like other sharks. If they hunt blacktips off south Florida then they probably only have to catch a shark once per month link.springer.com/journal/442

New paper on stingray activity patterns in Belize. There is lots of individual variability with regards what time of day rays are active, but all seem to be highly active in shallow water. These may represent important foraging habitats cdnsciencepub.com/doi/abs/10.1...

This is the first paper that I publish with undergrads from a statistical consulting & collaboration course I teach at University of Toronto. With TA help, they did an amazing job fitting hidden Markov models and learning about Goliath Grouper. Our undergrads are top notch 👌🏽 #AnimalMovement 🧪
