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 🐟 🐠 🦀 🦐.

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 🐟

Raby lab retreat this week at Harkness Lab of Fisheries Research was a great success!

Thanks to the ghost of F.E.J. Fry for writing inspiration 👻🐟

Measuring critical thermal maximum in aquatic ectotherms: A practical guide Critical thermal limits, commonly quantified as CTmax (maximum) or CTmin (minimum), are core metrics in the thermal biology of aquatic ectotherms. CTmax, in particular, has recently surged in popu...

Happy to see this out in @methodsinecoevol.bsky.social

Are you new to CTmax tests (or CTmin)? Are you experienced, but unsure on what to report in your Methods?🤔

Then this practical guide is for you! It even includes a fillable table! 😎

thanks! I'll redo the post :)

Thank you so much for accepting our invitation and joining our session! 😁

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 :)

SEB starts next week in Antwerp! Join us at our session on "Vulnerability of early life stages to stressors" (A14) with an incredible lineup of talks, posters and guest speakers! 🐣

Session starts Tuesday at 4:00 PM in Gorilla 3! 🦍

See you there! ✌️

@sebiology.bsky.social

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! 🐟

Happy to share my first thesis chapter from my PhD at NTNU, published in Journal of Thermal Bio! “No Oxygen limitation of Upper Thermal Tolerance in Zebrafish Regardless of Acclimation Temperature” 🔓🐟🌡️

🚨Preprint alert!🚨

We found that relevant levels of aquatic oxygen supersaturation do not always offer protective benefits to aquatic ectotherms during acute warming. 🌡️

Big collaborative project with A LOT of CTmax trials!!!

How do fish evolve to tolerate higher temperatures, and are there trade-offs? We explore these questions in our new paper

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

Are you new to CTmax tests? Are you experienced, but unsure on what to report in your Methods section? Do you think there any other factors at play? 🤔

Then this practical guide is for you! 😎

Glad I could be a part of this effort which could help with studies comparisons! 🤩

Thanks Jeff! 🤩

Thanks to the @gril-limnologie.bsky.social who helped fund this research project through travel grants 😄 🙏

Best group of people in the World <3

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!

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.

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).

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.
