Excited to see our work get recognized as Editor’s Choice in CJZ for April! ⭐️ We really enjoyed exploring new ways of analyzing telemetry data to quantify thermal habitat selection over short and long timescales 🌡️ ❄️ @harknesslab.bsky.social @tmiddel.bsky.social

The proofed version of our CJZ paper is now online! 🐟 We studied patterns of brook trout thermal habitat selection during peak summer temps in 3 Algonquin Provincial Park lakes 🏕️ With @tmiddel.bsky.social & @harknesslab.bsky.social @canjzoology.bsky.social dx.doi.org/10.1139/cjz-2025-0087

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.

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 👻🐟

The FINclub 2025 team (most of us)! Now off for the SEB conference @sebiology.bsky.social 🧪🐟

Some great talks on fish metabolism, thermal tolerance, and bioenergetics by folks from @trentuniversity.bsky.social at this year’s #SEBconference in Antwerp, Belgium. @sebiology.bsky.social @erinmcstewart.bsky.social @jaydebon.bsky.social @chris-on-fish.bsky.social

Visiting the nurse sharks at the Antwerp Zoo during #SEB2025 was a definite conference highlight!

A terrific afternoon for fish biology here at #SEBconference ❤️🐟 Great talks by @leeuwisrobin.bsky.social, Moa Metz, and @erinmcstewart.bsky.social about different ways that fish respond to climate warming!

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. 🧪🐟🦑

🚨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!!! ecoevorxiv.org/repository/v...

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... 🧪🐟🦑

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.

Thanks @zoe-storm.bsky.social for writing a great piece on our recent brook trout work! 🔥 ❄️ 🐟 Links to her ConsPhys in Action article & our research paper below ⬇️

Congrats to Graham Raby for winning the outstanding mentor award at AFS OC this weekend! Turns out we all had lots to say about what we think of his leadership skills ✨🥳

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. Preprint link below! 🧵

Going to @sebiology.bsky.social 2025? Consider submitting an abstract to our session on "Shared challenges & diverse approaches to physiology in conservation" open to ~all taxa~ 🐟🐻🦋🌿 Organized by Drs. Britney Firth, Sean Tomlinson, Zjef Pereboom & non-Dr me! #SEB2025

Are you headed to this month’s annual Society of Canadian Aquatic Sciences conference in Hamilton? Have students or are yourself new to the world of scientific publishing? Grab your lunch and join me to chat all about the process, tips and tricks ✍️ #SCAS2025 @cdnsciencepub.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! 🤩

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...

It was a pleasure to be Erin's research assistant on this project in 2021! Here are some of the amazing and variable streams we visited during our fieldwork.

We're back in February for more conservation science! Join Dr. Mark Ridgway for the scoop on Algonquin Park lake fish. There's more going on beneath the waters than we thought!

📣 Just published in @conphysjournal.bsky.social with @jacobbowman.bsky.social, Chris Wilson, and Graham Raby How much does upper thermal tolerance vary among wild populations of brook trout? What drives this variation? 🌡️ 🧵1/5 doi.org/10.1093/conp...
