Excellent article on the oxygen limitation during warming discussions, and our recent paper on the topic. By @dianasmadeira.bsky.social 🐟🧪

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.

The first project, during 2026, will be a global distributed test of thermal tolerance in the embryos of fishes. We are hoping for many species from various environments and climates. Please spread the word and join us! www.thermalecologyalliance.org#home

For those interested 🐟🌡️

You can use HusMorph to analyse images of fish — like the above example — or whatever your favourite study organism is 🐟🦐🥬 See our Toolbox paper in Conservation Physiology @conphysjournal.bsky.social for more info: doi.org/10.1093/conp....

Tired of manually landmarking hundreds of images? 📍🖼️😩 Our lab developed HusMorph, a free and open-source tool that automates morphometric landmarking using #MachineLearning — no coding required. Simply train the model on your images, and it quickly places landmarks with human-level accuracy. #AI

Sad that ChatGPT makes up two male scientists instead of the real scientists Andrea Franke and Catriona Clemmesen.

I think my PhD students want me to resign

What's the best free software for behavioural tracking? (videos of several fish in a shared arena) Toxtrac? Tractor? Trex? idTracker ai? Detect+Track? AnimalTracker? Other? Please help 🙏

I spend most of my time on research and I try to keep the teaching load down. But WOW, it is so inspiring when you meet students like this! Teaching ethics and robust open science practices to the new MSc cohort has been treat.

Notice anything fishy here? #ImageForensics 🐟🧪 (Too easy for you @elisabethbik.bsky.social)

Cleaned out my office at NTNU, exactly 10 years after moving in. Looking at the list of people who passed through the lab, so many great scientists and friends! www.gu.se/en/research/... Yes, I feel a little sentimental.

😂 so rude, poor mola but a great video

Hilarious and mostly accurate character assassination of the sunfish Mola mola 😂🐟🦑 youtu.be/gtDKKJq9u30?...

New fish species keep popping up in Sweden, most likely because of ocean warming! Today a large Mahi Mahi in Lysekil! (Photo Janice Melander)

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.

If you have atleast 5 years of postdoctoral experience definitely consider applying!

Paper led by Graham Raby along with an awesome group of international collaborators! (#FINclub) @jutfelt.bsky.social

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....

Is European eel in terminal decline? I have investigated fishery-independent international trawl surveys in northern European waters, and indeed it doesn't really look bright. www.frontiersin.org/journals/fis...

This is very worrying! Zero eels per hour of fishing for many trawl surveys!

My least popular (and most correct) view is that cars should be automatically limited to the local speed limit. Put the pedal to the floor and you still can't go over 25mph in a residential area. (15 in Manhattan btw)

PhD position with great supervisor!

It's giving "local fish in a great mood today" vibes and I'm here for it

(Images of a fish and a diver in an eel grass meadow.) This one gets a bookmark from me. 🥰

The Kristineberg Underwater Observatory is now live!! 🐟🧪🦑 Similar to the @coralcitycamera.bsky.social. Watch the eel grass meadow full of life live from your desk! Gobies, crabs, pipefish, several species of wrasses including some massive Ballan wrasse. Enjoy! www.youtube.com/live/goB60IJ...

Cell people, please advise! 🧪 We’re trying to find a microplate assay to check for acute upper thermal tolerance in fish cells. We need a marker for cell death that is fast acting and isn’t too temperature sensitive. 🙏

Fish are just the ancient ancestors of all terrestrial tetrapods. For whom we owe fealty and thanks for life on land. Some tie themselves in knots. Some are fully transparent. Some eat birds and mammals. They smile politely at the crushing pressure at the depths of the earth and our souls.
