#Communiqué 🗞️ En 2050, la majorité des écosystèmes insulaires seront menacés par les changements globaux : 65% principalement par le changement climatique, 22% par les changements d’usages des terres, 13% par les invasions biologiques. 🏝️ ➡️ www.cnrs.fr/fr/presse/la...

Almost every European plant species is out of equilibrium. Climate change is only part of the story—disturbance greatly shapes where species actually occur. 🚨Our new paper 🌱in @natecoevo.nature.com analysed 3,047 species across >1.1M European vegetation plots. www.nature.com/articles/s41...

Yesterday we shared the paper. Today I want to share the story behind it. We thought it was all about climate change. Then the models failed. That failure eventually led us to disturbances, and to a very different view of Europe’s flora. Read it @ communities.springernature.com/posts/europe...

This year, at IAVS 2026 in Gijón, I am presenting a new version of my poster, also handmade and painted in watercolor! 🎨 Thank you to everyone who came to see it and for all your very positive feedback, it's very motivating! 😊 @iavs5.bsky.social @iavs-young-sci.bsky.social

Two years ago, I presented my doctoral work for the first time on a poster that I had drawn by hand and painted with watercolors 🎨 @jonlen.bsky.social x.com/EkoLogIt/sta...

I'll be at P189 tomorrow—come say hi and chat about microclimate predictions from sampled forest vegetation! #IAVS2026 @iavs-young-sci.bsky.social @iavs5.bsky.social

The first comprehensive analysis of vegetation changes across Europe, based on the ReSurveyEurope dataset, is out! In an article led by Stephan Kambach, we analyzed 57,390 time series of vegetation plots. doi.org/10.1038/s414...

Climate niche models underestimate the speed with which species move in response to climate change, according to comparisons between the models and observed shifts for more than 3,500 species. Median rates were four times faster than predicted. In PNAS: https://ow.ly/Mokn50YCqty

#Communiqué 🗞️ À l’heure où le réchauffement climatique redessine la carte mondiale de la biodiversité, une étude d’envergure internationale révèle un décalage majeur entre prévisions scientifiques et réalité observée. 👉 www.cnrs.fr/fr/presse/ch...

Des espèces se déplacent jusqu’à quatre fois plus vite que ne l’anticipent les modèles climatiques : c'est ce que démontre une nouvelle étude, avec l'implication de @jonlen.bsky.social #EDYSAN. @upjv-univ.bsky.social

Huge thanks to #BioScience for featuring our paper "Too Cute to Be Wild" on the cover of their March issue! 🐻🧸✨ doi.org/10.1093/bios... Never thought our work on teddy bears would take us this far! 💚 with @thierrybrassac.bsky.social, N. Blanc, N. Casajus, and A.S. Tribot 👏 🧪🌐🌍🦤

Genetic diversity shapes climate-driven species redistribution: 🚨Genetic diversity slows species range shifts, especially at the trailing edge and under rapid climate change—consistent with the evolutionary rescue hypothesis. onlinelibrary.wiley.com/doi/10.1111/...

Does genetic diversity help species keep up with, or tolerate, climate change? 🌡️🌍 Our new BioShifts paper shows that high genetic diversity 🧬: 1) Reduces range contractions under fast warming 2) Accelerates range expansion under moderate warming onlinelibrary.wiley.com/doi/10.1111/...
