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?...

Check out our new review on how to measure thermal tolerance! 🐟🌡️🧪

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....

Associate Professor position in animal physiology at the Norwegian University of Science and Technology (to replace me basically). An amazing permanent position at a great university! Please spread widely 🙏 www.jobbnorge.no/en/available...

Live underwater view from Sweden! 🐟🦑🧪 www.youtube.com/live/5ubnomi...

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.

Baby eel alert! The threatened European eel (Anguilla anguilla)

Gaza is being deliberately starved to death in front of the whole world, and the only people being arrested over it are those who opposed the crime.

Had a great time at this year's #SEBconference in Antwerp! So much interesting and inspiring science! Thank you @sebiology.bsky.social organizers for a wonderful event - and to all presenters for sharing their work and passions!

The SEB conference 2025 in Antwerp was fantastic! Thanks to the @sebiology.bsky.social team! Here are the conference photos: thephotoproject.smugmug.com/SEB-Annual-C...

This account (a.k.a., me) supports all sorts of parasites, plant and animal alike

Sandra Binning giving the President's Medallist talk on the importance of considering parasites for increased ecological relevance. Great presentation! 🐟🧪 #SEBconference @sebiology.bsky.social @jexpbiol.bsky.social

Foundations: please step up and take over the Biodiversity Heritage Library (BHL). This is an absolutely essential scanned archive of all of the old journals and books from the 1500s to about 1920. Has been indispensable for my research. about.biodiversitylibrary.org/call-for-sup...

🚨 Sweden's Nordea has backtracked on its #fossilfuel lending restrictions, becoming the first bank in Sweden to lower its lending requirements 🚨 An alarming backward step! Email the bank here: fairfinanceguide.se/sverige/tema... @fairfinanceint.bsky.social @nordeagroup.bsky.social

Warming waters mean new warm-water species! The venomous lesser weever and the gilt-head seabream have almost no previous recordings in Sweden but our catches may mean they’re getting more common. Photo and figure by Elena Tamarit.

New research paper out about how fishes acclimate to different water temperatures! 🐟 It's in @conphysjournal.bsky.social and OA! 🔓 doi.org/10.1093/conp... We looked at the role of blood plasma factors and skin temperature sensation in this study 🩸 ♨️ Recap in the threat below for those interested 😊

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. 🧪🐟🦑

Hyperoxia expands AS but offers no benefit during extreme acute warming. Only extreme hypoxia (30% air sat) reduces their warming tolerance.

Happy to share my first thesis chapter from my PhD at NTNU, published in Journal of Thermal Bio! “No Oxygen limitation of Upper Thermal Tolerance in Zebrafish Regardless of Acclimation Temperature” 🔓🐟🌡️ @jutfelt.bsky.social @annahandreassen.bsky.social @rasmusern.bsky.social

Swedish carbon emissions up by almost 6%! This right wing government is failing our climate commitments!

Sturgeon surprise! 🧜‍♀️

There is still time to apply for this post. DL extended until 15 June. Read more and apply 👇 @biologylu.bsky.social @erc.europa.eu #HotLife

So glad we did a datacamp-writing-retreat at Kristineberg Center for Marine Research and Innovation. Doing parts of a project that normally are stressful and difficult was infinitely easier in such a beautiful place with lovely people and other organisms ☺️ Thanks also @jutfelt.bsky.social!

Zebrafish bred for #heat tolerance showed no fitness trade-offs — surprisingly, they also coped better with cold. But can wild fish adapt as quickly? #Study in 'Nature Climate Change' offers new insights. DOI: doi.org/10.1038/s415... 🧪🐟 🌏

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... 🧪🐟🦑
