How useful is underwater video as a fisheries assessment tool in freshwater? @jacobbowman.bsky.social asked this question for his honours thesis, by comparing video against other ways of counting fish. Editor's Choice in TAFS: academic.oup.com/tafs/advance...

New Year's coming, and with it more great conservation talks! This January's it'll be Trent's own Dr. Mary-Claire Buell, on bringing community + environmental forensics together in investigations of pollution. Should be great!

This new paper was a team effort among students in my lab, led by @mitchellshorgan.bsky.social. Please share with your fish tracking colleagues! @oceantracking.bsky.social @glatos-fish.bsky.social link.springer.com/article/10.1...

And we're back in action Dec 9th! Join us at the Publican at 7:30 pm for drinks, good company, and an account of the conservation fight for arctic shorebirds with Paul A. Smith

In this new study, we provide new data relevant to the debate about whether oxygen limitation is a universal driver of thermal tolerance in water breathing animals. News story: www.trentu.ca/news/story/2... Paper: journals.plos.org/plosbiology/... Primer: journals.plos.org/plosbiology/...

CONGRATULATIONS! Larkin Award, PhD Winner #BradleyHowell 🪼 [Graham Raby, #TrentUniversity & Steven Cooke, #CarletonUniversity] 🪼 Bradley’s research focuses on using telemetry and respirometry data to assess #predatorprey interactions and movement patterns that raise predation risk.

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 is proposed to buffer against #HeatStress in water-breathing animals. @graham-raby.bsky.social @jutfelt.bsky.social &co re-examine this question in diverse #aquatic #ectotherms, showing that #hyperoxia has minimal impact on thermal tolerance @plosbiology.org 🧪 plos.io/43hzMQa

Very exciting to finally have this work out there. Thanks to the team at @plosbiology.org for being willing to publish null results!

Special thanks to @dianasmadeira.bsky.social for authoring this thoughtful primer about the study we published this week in @plosbiology.org Good suggestions about all the work we still need to do to unveil the mechanisms underlying variation in thermal tolerance. journals.plos.org/plosbiology/...

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.

Excited about a new preprint from PhD candidate Megan Heft, showing that nestling provisioning rates in male tree swallows are not limited by the male's risk of overheating (in contrast with previous studies of females) 🧪 #ornithology #science www.biorxiv.org/content/bior...

If you're a fish tracking nerd you know and love the sight of this pink foam

Caught a couple northern sunfish in a beach seine today; first time ever seeing these for me (in the Otonabee River near Trent U).

is this what the discovery grant panel looks like

Incredibly nerdy paper, but should be useful I think. This was a product of a pre-SEB writing retreat a bunch of had in Czechia last year.

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 👻🐟
