Long before intensive human fishing began, Pacific reefs naturally supported far more sharks than Caribbean reefs, according to a new Science study. Learn more in this week’s issue: https://scim.ag/4x3GBBO

The Hampshire savannah this morning

Nice chalk stream pub lunch today… spot the fish…

Reposting as I was a bit distracted when this came out! @stableisotopeecol.bsky.social

Fab, thought provoking talk by @bd-stew.bsky.social about the value of citizen scientist- & fisher-collected data. From octopi to sharks, we can learn a lot from people who are in the sea every day (while we tap away on laptops & social media!). Get out there and talk/build relationships 🙌 #FSBI2026

The #FSBI2026 programme has officially been opened by esteemed guest, Lieutenant Governor of Jersey, Vice Admiral Sir Jeremy Kyd KBE! We also hear from the FSBI's honorary President, David McKenzie, who welcomes delegates and highlights the value the FSBI brings to the community.

1st talk of #FSBI2026 is from Jack Jones awardee, Rashid Sumaila, who pays tribute to Jack Jones while also professing to be the "silo smashing guy"! Rashid's talk "MPAs as economic correctives" explores ocean governance beyond western, educated, industrialized, rich and democratic economics.

So many wonderful, thought provoking talks at #FSBI2026! From weird economics to shark tooth jewellery to tagging to metapopulations to stakeholder engagement to fisheries management. So diverse and interesting!! @thefsbi.bsky.social

Sunny morning start for #FSBI2026! Excursions and workshops today ahead of talk program starting tomorrow. Looking forward to welcoming people to Southampton. @thefsbi.bsky.social

First leg of our #FSBIGreenTravel journey complete! #FSBI2026 Essex contingent incoming! 🐟🐟🐟 Share your Green Travel stories (even if they arent as exciting as you swimming to Southampton) on social media, and remember to tag #FSBIGreenTravel to be in with a chance of a prize! @thefsbi.bsky.social

New paper alert!!! 🚨📃🚨 Led by the awesome Sarah Magozzi and with @clivetrue.bsky.social and many other data contributors, we test isoscape construction in the Med using extensive compiled opportunistic data (1000's of measurments) doi.org/10.1016/j.po...

🏅 Beverton Medal #FSBI2026 Simon Jennings is recognised for ground-breaking research and a lifetime contribution to fisheries science. His work has advanced ecosystem-based management and strengthened links between research and policy. More: bit.ly/4bi6mVO

Just back from my first #ICBF2026 meeting -thanks@thefsbi.bsky.social - Really stimulating time interacting with experimental and field fish physiologists, mechanistic and applied science, even non-salmonids! Hope to keep in touch with new and old friends. Next up #FSBI2026 in Southampton!

Excited to share our paper in Ecology Letters @pzecology.bsky.social@jimjunker.bsky.social ker.bsky.social@wesnerlab.bsky.social! 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 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..

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...

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

Press release for our new paper! “…people across the world created inclusive political systems, even under difficult conditions…An understanding of the hallmarks of autocracy and democracy can help identify threats and pump the brakes on burgeoning totalitarian regimes.” phys.org/news/2026-03...

Check out my recent #JFB Editor's Choice: "Uncovering the lazybones of the shark world": doi.org/10.1111/jfb..... Stable isotopes, going beyond identifying where a fish has come from, or where it has been - now providing data on life-history traits! Paper by Delgado et al doi.org/10.1111/jfb....

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!
