How useful is underwater video as a fisheries assessment toolย in temperate freshwater ecosystems?
ABSTRACTObjective. Remote underwater video (RUV) is a noninvasive survey technique that has long been used in marine ecosystems and is now gaining interest

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!

More Oxygen Wonโt Save Fish from Warming Waters

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.

Very happy and proud to see this one published! Have a look at this global assessment of the effect โ or lack of effect โ of extra oxygen (hyperoxia) on ectotherm thermal tolerance! Led by
@graham-raby.bsky.social
and a team of incredible collaborators working on multiple taxa ๐ ๐ ๐ฆ ๐ฆ.

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) ๐งช

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.
