🌊The ocean covers 70% of our planet 🌊About 50% of the Earth's oxygen production comes from the ocean 🌊The ocean absorbs around 25% of anthropogenic CO2 emissions Yet 40% of the ocean area is heavily altered.🚨 On #WorldOceansDay, dive into some details from the #GlobalAssessment 🌍

Symbiotic diversification relies on an ancestral gene network in plants
Symbioses have been fundamental to colonization of terrestrial ecosystems by plants and their evolution. Emergence of the ancient arbuscular mycorrhizal symbiosis was followed by the diversification o...

Des écosystèmes entiers s’effondrent sans bruit. Pourtant, les débats restent centrés sur notre confort, notre économie, notre climatisation. L’humain au centre, comme toujours. En Méditerranée, des températures de surface de la mer ont atteint 32°C, avec une anomalie thermique de +6,21°C. [1/5]

We got a message from the university to remove any use of the "DEI", "diversity", "equity", or "inclusion" from all public-facing documents. They said that even "biodiversity" is being flagged by the federal government. We live in the dumbest timeline.
