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.

🚨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!!!

Really enjoying the Conservation Physiology in Action articles written by early career researchers. This one by Zoe Storm from JCU, commenting on the fine work by @erinmcstewart.bsky.social and team.
Home is where the heat is (for brook trout that is)
Intrigued? Then check out this latest #ConPhys in Action piece, explaining the importance of local conditions to 🐟 temperature tolerance, and therefore for #Conservation planning.

What are the effects of tagging on fishes? 🐟
Our review + meta-analysis explores intracoelomic tagging effects in fishes. We summarize the existing literature and examine the 2% rule using evidence from a broad representation of all published studies.
