Are warmer oceans good or bad for #fish? 🐟 The answer is a dangerous paradox. Our new paper in @natecoevo.nature.com shows how marine heatwaves may create “fake” fish gains that mask a large-scale crash. Read our findings here: www.nature.com/articles/s41... @mncn-csic.bsky.social #ClimateChange

When I scan through open peer reviews I'm surprised by how rarely people comment on the design of visuals. I've been working to develop a constructive approach to critique and have been trying them out on the Tube. Here's the latest www.youtube.com/watch?v=zWpt...

New paper out examining fish food web degradation in the Anthropocene. We show the structure of aquatic food webs are changing-- even when species richness doesn’t. These signals are strongly associated with decreases in body size within fish communities. www.science.org/doi/10.1126/... 🌐🐠🐡🦈🐟

What happens when fish communities shift towards smaller species?🐟 Global study led by alumnus @juancarvq.bsky.social shows widespread changes in food webs across marine & freshwater systems. Even where species numbers stayed stable, interactions & body size changed. 🔗 www.idiv.de/smaller-fish...
