New paper! We looked at the impact of decades of eutrophication on different fish traits including metabolism, hematology, gills and morphology. Bottom line: we are modifying wild fish with our activities😱 authors.elsevier.com/a/1jFxZ… @AquaticSciences @physiologyfish @Ifremer_fr

So proud of Felix Astejada for defending his MSD thesis today about #cuttlefish beak vs eye lens C and N #isotopes. Big thanks to @johnkpinnegar and @ecoevoenviro for being wonderful examiners and to @rui_vieira19, @ejogorman and Vlad for being ace cosupervisors. What a journey!

So proud of my postdoc "Dr Cod" @DubucAlexia & Eric Fakan for collecting sediment, water, blood & #otolith samples from all around the #Baltic to explore the underpinning of oto Mn as a #hypoxia marker. BIG thx to BITS crew & our collaborators at @DTUtweet for their support 🙌

Successful #bass sample from Jaywick in Essex today. Such a great crew! A few teeny ones in there too.... maybe arrivals from a recent local spawning event? 🧐 @EssexLifeSci

Happy to announce the publication of the first chapter from my PhD!! Here we show evidence of co-gradient variation within a coral reef #fish on the #GBR across a #thermal gradient. Also, happy to announce that the article is #OpenAccess ! @DrJDonel DOI: doi.org/10.1093/conphys/coae…

Selection of nursery habitats by marine fish, such as European sea bass (Dicentrarchus labrax), is poorly understood. Identifying and protecting the full range of juvenile nursery habitats is vital...

Future climate warming threatens coral reef function on World Heritage reefs

The future health of coral reefs under ocean warming is a pressing concern for the millions of people worldwide who depend on reefs. We show that World Heritage reefs will face significant loss of...

Nice new paper out from our PNG expedition! Out of shape: Ocean acidification simplifies coral reef architecture and reshuffles fish assemblages @OISTedu @celiaschunter @physiologyfish @RMetalpa #climatechange #seeps #volcano #coralreef #fish https:// besjournals.onlinelibrary.wi…
Out of shape: Ocean acidification simplifies coral reef architecture and reshuffles fish assemblages

Out of shape: Ocean acidification simplifies coral reef architecture and reshuffles fish assemblages

Many small-bodied reef fish are strongly associated with structurally complex corals. However, under acidified conditions, massive corals often outcompete branching corals, leading to reef ‘flatten...

Sleep occurs across animals, yet we know almost nothing about interactions among sleep, ecology, and environmental change. Our new systematic review led by Helena Norman reviews sleep in fish and avenues for future research in this fascinating field: journals.biologists.com/jeb/…

So proud of this crew. Dissecting Atlantic #salmon heads all day to see what secrets their #otoliths & eye lenses reveal. As these fish had died naturally & had often festered the smell was 🤮! HUGE thx to the river crews for collecting these precious samples! #TakesAVillage 1/2
