🧵1/9 There are 35,000+ fish species, but we have formal social-behaviour classifications for a tiny fraction. Most knowledge lives in the experience of researchers, fishers, divers, aquarists, naturalists, and Indigenous communities, but almost none of it is centralised. So we built ShoalBase.org.

Oxygen limitation is considered a key mechanism of #ThermalTolerance. @dianasmadeira.bsky.social explores how a @plosbiology.org study challenges this idea, showing minimal protective effects of O2 supersaturation in heat-stressed #aquatic #ectotherms 🧪 Paper: plos.io/43hzMQa Primer: plos.io/3XeUtbS

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.

📖Published📖 Raby et al. provide a comprehensive, practical guide for designing and conducting experiments to measure critical thermal limits, with an emphasis on CTmax 🌍 🧪 👇 buff.ly/iZN6Xdg

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! 😎 besjournals.onlinelibrary.wiley.com/doi/full/10....

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...

FINclub research trip going well! 32 people, dozens of fish and invert species, 16 experiments, two dogs and lots of fun. Some photos in thread. 🧪🐟🦑

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 😊

Little is known about the mechanisms controlling thermal acclimation in fish. Check out this study exploring possible roles of hormones & skin thermoreception during acclimation in goldsinny wrasse. 🐟 Read it here: academic.oup.com/conphys/arti...

How do fish evolve to tolerate higher temperatures, and are there trade-offs? We explore these questions in our new paper @natclimate.nature.com led by Anna Andreassen @annahandreassen.bsky.social www.nature.com/articles/s41... 🧪🐟🦑

It was great to see so many wonderful talks and presentations at the RE Peter Biology Conference last week hosted by @ualberta.bsky.social! In particular, the keynote by @rachaelmorgan.bsky.social on how temperature and oxygen changes can impact fish was fascinating! 🐟 repeterconference.weebly.com

New paper in @nature.com led by @patricepottier.bsky.social! We demonstrated global vulnerability of amphibians to warming, threatening 10% of >5,000 species examined. How did we do it? See thread🧵 Paper: www.nature.com/articles/s41...

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! 🤩

In this new preprint on ecoevorxiv we provide a detailed, practical guide to measuring CTmax and CTmin in aquatic animals. Amazing team of authors! 🧪🐟🦑 Raby @rachaelmorgan.bsky.social Andreassen @erinmcstewart.bsky.social @jaydebon.bsky.social ecoevorxiv.org/repository/v...

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!
