Very happy and proud to see this one published! Have a look at this global assessment of the effect – or lack of effect – of extra oxygen (hyperoxia) on ectotherm thermal tolerance! Led by @graham-raby.bsky.social and a team of incredible collaborators working on multiple taxa 🐟 🐠 🦀 🦐.

Oxygen supersaturation has been reported to protect aquatic animals from heat waves. We tested this in a large collaborative experiment on many species of fish and crustaceans. Our new paper in @plosbiology.org shows that the effect of hyperoxia on thermal tolerance is negligible. Unfortunately.

Final chapter of my PhD is “Just in” @canjzoology.bsky.social. We tested how different parasites can affect swim performance in pumpkinseed sunfish through physiological or drag-induced effects! Check it out 🐟 @gril-limnologie.bsky.social

Thank you to our incredible sponsors making this session possible : Loligo Systems and Pyroscience! We will be offering student travel grants and organizing a session dinner thanks to their generous contribution :)

Congrats Robin!!! Very grateful to have been a part of this awesome project! Have a look at it to learn more about how fish acclimate! 🐟

New research paper out about how fishes acclimate to different water temperatures! 🐟 It's in @conphysjournal.bsky.social and OA! 🔓 doi.org/10.1093/conp... We looked at the role of blood plasma factors and skin temperature sensation in this study 🩸 ♨️ Recap in the threat below for those interested 😊

The deadline to submit abstracts is approaching!!! ⏰ (March 7th) Consider submitting an abstract for a talk or poster in our session (A14) if you study the vulnerability of early life stages to environmental stressors! 🐣 The early bird registration deadline is May 16th.

Hey you! Yes...you! You study early life stages? You like multiple taxa? You should consider presenting in our session: Vulnerability and adaptations of early life stages to environmental stressors (A14). 🚨Deadline : March 7th 🚨 See you at the #SEBCONFERENCE in Antwerp!✌️ @sebiology.bsky.social

Big shout out to the FIN club who made this accomplishment possible! It was a pleasure working with you all <3 This is FIN club paper #12! Keep your eyes peeled for more fish science coming this year!

We found no strong differences in CTmax between adult and juvenile zebrafish, but CTmin was generally higher in juveniles, albeit following a similar acclimation pattern than adults. Both life stages showed a longer t induction to lower tolerance (>24h) compared to upper tolerance (3h).

Although certain shallow water species showed rapid acclimation, the goldsinny wrasse, found in deeper water, had the highest acclimation capacity (ARR). For each degree increase in acclimation temperature, they gained the most thermal tolerance.

Acclimation dynamics patterns differed among species, as some reached full acclimation (t steady) as fast as 4 days, such as the zebrafish, European flounder and three-spined stickleback. Whereas the goldsinny wrasse did not seem fully acclimated after 10 days.

Furthermore, it only took 3h for the stickleback to increase their baseline thermal tolerance, compared to the wrasse or flounder which took longer, showing a low t induction for the stickleback and rapid acclimation dynamics.

We assessed acclimation capacity (ARR), and two new metrics we proposed: response induction time (t induction) and time to full acclimation (t steady). These metrics can help assess a species vulnerability to fast warming/cooling events to understand how rapidly they can thermally acclimate.

We measured CTmax and/or CTmin in 4 species and 2 life stages of zebrafish across multiple acclimation durations to a warm treatment. This allowed us to detect fast changes in thermal tolerance across time.

Post-doc position available! Join us in this exciting project where we will use more than 100 years of data to investigate habitat choice and availability of the elusive European eel. The position will be based at SLU Aqua in Stockholm. Apply before January 7. Please repost!

ohhh lookie here it’s our paper!! 🧪🌎🌐🐠👩🏻‍🔬🐡🎨 sturgeon are more thermally plastic than other fish (they can increase their thermal tolerance per acclimation degree) !! but warm temperatures seem to have negative impacts on growth and survival in early life stages. We need WAY more data on older fish

Hey all! I’m Jay. I’m an ecophysiologist interested in the thermal biology of fishes (and how parasites play a role in it). Wrapping up my PhD in the Binning lab at Université de Montréal! 😏 I did a couple CTmax tests during my PhD. I have a son (🐈) and a baby sister (🐶). Big Pokémon fan here!
