A huge thank you to @efe.com for their fantastic coverage of our new paper in Nature Ecology & Evolution today! 🌊🐟 efe.com/medio-ambien... @mncn-csic.bsky.social @mncn-bgcg.bsky.social @miguelbaraujo.bsky.social @jdgonzalezt.bsky.social

Thank you to @theguardian.com for doing such a fantastic job communicating our findings to the public today. You can read their coverage here: @mncn-csic.bsky.social @miguelbaraujo.bsky.social @csic.es www.theguardian.com/environment/...

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

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/... 🌐🐠🐡🦈🐟

We are proud to unveil the world’s longest underwater timelapse, starting May 1st 2023 and running 1,000 days through January 28, 2026. This 10fps period covers summer 2023’s coral bleaching mortality event, but then recovering and growing through ‘24 & ‘25 into ‘26 #coralcitycamera

We should not isolate #range_expansions and #Introductions! 🌊🦀 "An invasion is an invasion". Whether a species arrives via ballast water or a warming-driven poleward shift, it is a historical newcomer to that community. Essential reading for anyone in #Biogeography or #InvasionEcology

The thermal position of marine population matters for #kelp persistence in the face of #marineheatwaves Warm-edge populations of foundation species suffer more from acute short-term warming compared to cold-edge ones. #goldenkelp #climatechange onlinelibrary.wiley.com/doi/10.1111/...

Israel’s gov considers quitting the Paris Agreement, calling the climate crisis a "hoax". The Trump effect is sadly taking us down... So much lack of responsibility and #egoism May this government fall soon. #ClimateChange #MarineScience #ocean #Research #Israel #climate_crisis

It was pleasure attending the TIBS conference in Aarhus! I had some fantastic discussions with researchers on how we can better quantify the impacts of climate change on marine species. Leaving with new ideas and collaborations. 🌊🐟 @tibsaarhus2026.bsky.social #oceans #fish @biogeography.bsky.social

📢 We’ve published a comprehensive depth dataset for 230 fish species in the Eastern Med & Northern Red Sea. Derived from systematic stereo-BRUVs surveys, it includes: Modeled central depth niches🔹 Abundance🔹 Body size🔹habitats (link in thread below) #data #fishes #marine #invasions #depth #aliens

Does ocean warming mean fewer fish? It’s complicated. 🐟 We analyzed 33k+ populations and found that while long-term warming drives declines, heatwaves create sharp "winners" and "losers" at range edges. 🗓️ Fri, Jan 9 | 14:10 - 15:40📍Session: Aquatic Biogeography #TIBS2026 @miguelbaraujo.bsky.social

Another successful lab retreat at @miguelbaraujo.bsky.social Lab! Thanks everybody for providing important, instructive comments on binding fish biomass data with species-level thermal limits. This project is about to be very interesting. #macroecology #macrophysiology #climatechange

It took twenty years for the horizon to disappear. I made this to capture the specific sadness of watching the open fields of my childhood turn into concrete. It wasn’t just a change in scenery; it felt like the world actually got smaller. 🧵 #Urbanization #Nostalgia #ShiftingBaselineSyndrome

#iDiv sabbatical @miguelbaraujo.bsky.social kicks of the annual conference of @idiv-research.bsky.social w an intro into modelling under #climatechange & a very interesting intro how to incorporate network properties into it #iDivconference2025

Check this out! I took one of my old research studies and turned it into an engaging, public-friendly animation. Science for everyone! 🧠 #spacefortime #depthredistributions #warmingimpacts #fish youtu.be/I5C22DhwRDM?...

I've been debating for a long time whether or not to share this publicly. I'm doing it now because I believe that only by sharing the raw, personal trauma may some understand that this isn't politics—it's about the basic right to life and dignity. #TwoYearsLater #CollectiveTrauma #October7th

Happy to have attended the @mncn-bgcg.bsky.social department gathering in El Ventorrillo! ☀️ It was inspiring to hear about the high-quality research others are doing, sparking ideas for future collaborations. I was also happy to get the chance to present my own research interests and recent work.

New data on 2023's marine heatwaves is alarming. Oceans hit unprecedented temps & durations, with some events so extreme they're considered once-in-centuries occurrences. It's a clear signal that warming climate impacts are accelerating. www.science.org/doi/10.1126/... #unprecedented #oceanwarming

Claims by the Trump administration that marine protected areas are a heavy-handed restriction on the U.S. fishing industry do not hold water. Science shows these refuges for sea life help local economies and allow fish populations to thrive By @whysharksmatter.bsky.social

US President Donald Trump’s proposed budget for fiscal year 2026 calls for unprecedented cuts to scientific agencies that, if enacted, would deal a devastating blow to US science, policy specialists say. https://go.nature.com/4jYv3IP

We show that marine communities around the world exhibit trophic convergence in similar environments — a global pattern echoing what we also found on land. This challenges classic biogeographic models and opens new doors for predicting biodiversity responses to change. www.pnas.org/doi/10.1073/...

Interesting read on a core question in species redistribution research: abundance vs. occurrence data. Turns out, the choice really matters – authors show that they lead to different estimates. 🤔 onlinelibrary.wiley.com/doi/10.1111/... #ecology #biogeography #speciesdistribution
