Ever heard about “phantom recoveries” and “overfishing ratchets” ? These explain why still so many fish stocks are in a bad shape in European waters despite binding goals of the EU fisheries policy. www.science.org/doi/10.1126/...
Systemic failure of European fisheries management
Overcoming shortsighted interests with politically independent ecosystem-based catch limits may end overfishing in EU waters

‘Biodiversity is not declining’ is a claim you may have heard. But science says otherwise. 📉

The @ipbes.net #GlobalAssessment reveals 1 million plant & animal species are at risk of extinction. Misinformation clouds the crisis.

Rely on trusted research to understand our shared challenges. 🌍🧪

Follow this project about Swedish kelp forests! #KelpIT
KelpIT is project about Swedish kelp forests, staring in 2025. We will use innovation and technology to advance our understanding of kelp forest distribution, health, and status.

Thanks for participating. Three days learning together
On my train back from three fantastic days at the AZTI #summerschool25 on “Artificial intelligence and citizen science in monitoring and assessing biodiversity and invasive species at sea” in beatiful San Sebastian. Thanks to @drangelborja.bsky.social @helianateixeira.bsky.social and all involved!

Our community science project begins in more or less 24 hours from now (depending on your time zone!)

If you're going out to spot your local wildlife, join our project here so your findings can be used for a lot of science stuff

Looking forward to our session this afternoon, interacting with important projects such as #GES4SEAS, #LIFE-PROMETHEUS, #LIFE-RELIONMED, #LIFE-DUNIAS, #ClimateInvasives, #B-cubed, #LIFE-RIPARIAS

#GuardiasOnestopKickoff
Today, I'm presenting our #GES4SEAS project at @guardias.bsky.social kick-off meeting, looking for potential collaborations between both projects (such as the @azti.bsky.social summer school this June) @skatsanevakis.bsky.social @helianateixeira.bsky.social

Check our new paper reporting that Mediterranean seagrasses provide essential coastal protection under climate change.

Bottom line: Seagrass loss may double the risk of coastal flooding with rising sea levels.

Ocean faces multiple threats, such as human activities and #climatechange, managing these is complex, as a Rubik cube. However, using scientific knowledge it can be tackled. See our fantastic #GES4SEAS video

We often focus on global surface temperatures as a key metric for climate change.

But as we note in the Climate Trends chapter of the new US 5th National Climate Assessment, we see incontrovertible evidence for climate change across the oceans, land, cryosphere, and atmosphere:

Today we publish a new paper on a molecular phylogeny of true crabs. We find crabs transitioned from marine to non-marine environments 7-17x over 100+ myr! This culminates 15+ years(!) of effort from an international team! 1/4 (thread in replies)
