Excited to share our paper in Ecology Letters @pzecology.bsky.social@jimjunker.bsky.social [email protected]! Using ~670,000 body sizes from stream food webs across North America, we show that warming does not necessarily favour smaller organisms, but depends on resource supply🌍🐟

🕺#FSBI2026 social update! Join us for a week of workshops, excursions, networking and social events, including the Gala Dinner at the Harbour Hotel on 30 July. Expect great science, great company, and a fantastic programme throughout the week. More info: tinyurl.com/FSBI2026Soci...

Really excited to be talking this morning at the inaugural MidSEC conference in Backaskog, Sweden 🐟

This is a cool discovery - maybe expected but still cool to see. I was judging headlines by whether they used ‘’ around ‘graveyard’ - but the article has necropolis without.. wish people didnt imply or encourage inference of agency or behaviour esp for popular reads.. www.nature.com/articles/s41...

What's the most abundant vertebrate on earth? Forms a crucial link in the global #carbon cycle? And why don't we have any idea whether this group is adapting to #climate change and ocean #acidification? Led by my postdoc @evolbyo.bsky.social and #NSF funded - now we know! #lanternfish 🐟🏮💡🌊

🚨 New paper alert! Delighted to have been involved in this @nature.com study using trait-based ecosystem modelling to examine plankton extinction patterns in the first *100 years* after the Chicxulub impact event at the #Cretaceous-Paleogene boundary. ☄️ www.nature.com/articles/s41...

New research highlighting the utility of #MuseumCollections and #stableisotopeecology. @williammills.bsky.social and others found that brown skuas in the Southern Ocean have shifted wintering strategies over the past 100 years, moving to more oceanic subantarctic waters. doi.org/10.1098/rsos...

We are delighted that Professor Alberto Naveira Garabato has been elected to the Fellowship of @royalsociety.org. It is one of the highest honours a scientist can receive and recognises Alberto's immense contribution to oceanography. Find out more: https://southampton.pulse.ly/hikofge7ab

Check out my recent #JFB Editor's Choice: "What big eyes you have! Well, until 500 m, that is": doi.org/10.1111/jfb..... Using an incredible image repository, authors show that larger eye investment peaked at 500m, after which expensive eye structures weren't worth it. Paper by Pinti et al.

A good few degrees cooler than southern England here in Rhossili.. still a LOT of pink skin on show..

Harrowing knowing someone has been found guilty, with evidence, of serial harassment and professional misconduct to own students (of minority status). And faced no consequences, just a raise, new position abroad, and a Nature paper. Academia and palaeontology are a hotbed of lawless misconduct.

I am recruiting Ph.D. students this cycle. Students interested in deep-sea fishes and phylogenetic comparative methods are an especially good fit.

I'd forgotten just what an album this is...

For those who reached out asking how to help: This gofundme is specifically for graduate students who lost personal items, computers, tablets, etc. in the fire. We were told that these items are not retrievable or reimbursable -an added burden for students during a devastating time. Plz share 🌊💙

New article led by Anna Kebke! 🐳 🏴󠁧󠁢󠁳󠁣󠁴󠁿 🧪 journals.plos.org/plosone/arti...

There are more individuals of the deep-sea fish Cyclothone than any other vertebrate genus, maybe as many as one million billion. Distinctively ornamented ichthyoliths place the origin of Cyclothone in the greenhouse world of the early Eocene, ~55.6 Ma. royalsocietypublishing.org/rspb/article...

Wrasse are used as cleaner fish in salmon aquaculture, however their performance may be affected by thermal & ontogenetic changes. This study analysed chemical markers in wrasse at different sites to understand the conditions in which they are most productive 🐟 Read here ➡️ doi.org/10.1093/conp...

This study sampled whale baleen from museum specimens to study long term hormone patterns in bowhead whales 🐋 . The results provide clues into whale reproduction and stress over decades, while providing a useful baseline for future research. Read it here ➡️ academic.oup.com/conphys/arti...

Just back from Belize. Definitely recommend... maybe more pictures to come...

Hi all. I am very excited that after 6 years I finally got my phylogenetic comparative methods book and online exercises online. Feel free to use and share. The book is here: nhcooper123.github.io/pcm-primer/. Note that it is not finished, we had to abandon it before the sunk costs fallacy broke us

Fish will have to adapt to a warming world, what will that adaptation do to fisheries yields? We answer that question today in Science. I’ll summarise our findings very briefly in this thread www.science.org/doi/epdf/10....

It’s started!

Nice large data analysis on fish biomass / distribution response sto warming - species' thermal position within range clearly moderating observed responses www.nature.com/articles/s41...

This is the Gov looking for your input on the BBC. It takes a while to complete (15/20 mins) but it’s pretty comprehensive and covers most aspects. Please share. I’m surprised many people haven’t seen it yet. www.gov.uk/government/c...

We face two potential missteps in ecophysiology: 1) measuring animals under socially unrealistic conditions & 2) extrapolating results to nature, where social dynamics alter trait expression, plasticity, & evolutionary outcomes. Our new commentary in @jexpbiol.bsky.social : doi.org/10.1242/jeb....
