One more week to apply! if you are a few years past your PhD and interested in advancing marine genomics and population genetics, come to Kiel, Northern Germany, to join a thriving, collaborative research and teaching environment.

Systemic failure of European fisheries management Overcoming shortsighted interests with politically independent ecosystem-based catch limits may end overfishing in EU waters

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/...

A split-screen image. The left side shows a rhinoceros mother and calf in a savanna landscape with scattered trees. The right side depicts a forest fire scene with orange flames and silhouetted trees against a dark sky. Text reads: "Biodiversity is in crisis" followed by: "1 million plant and animal species risk extinction Ecosystems are collapsing Misinformation slows progress." "Trust the science. Conserve, restore and sustainably use biodiversity."

‘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. 🌍🧪

Thanks for participating. Three days learning together

Thanks to all organizers, staff, presenters and participants for three days of informative lectures, inspiring discussions and great networking at the AZTI #SummerSchool2025

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!)

Reality check: coral restoration won’t save the world’s reefs New research examined coral restoration projects worldwide to calculate what it would actually cost to bring back what’s already been lost.

"It is therefore financially impossible to tackle the ongoing loss of coral reefs with restoration, even if local projects can still provide some benefits." theconversation.com/reality-chec...

SUMMER SCHOOL 2025 “Artificial intelligence and citizen science in monitoring and assessing biodiversity and invasive species at sea” - AZTI Summer School 2025 will focus on innovative and practical tools for monitoring and assessing human pressures on biodiversity in marine systems.

Heyyy!! #MarineResearchers!!!
Our new @azti.bsky.social summer school is here, on #AI and #citizenscience to monitor the #ocean and #biodiversity, with 6 Horizon EU projects #GES4SEAS #Obama-Next @guardias.bsky.social etc.

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

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)

A good overview (in Swedish) on the risks involved with allowing a continued high fishing pressure on weak herring stocks in the Baltic. The EU Council of Ministers neglected the suggestion for drastic decreases in quotas by the Commission.
