Most vascular plants' distribition are in disequilibrium w/ current climates, w/ species ranges best predicted by climatic conditions 10-18 yrs before sampling, especially so for closed-canopy species 🌳🌳🌲🌲 ➡️ Lagging dynamics or microclimatic processes ? @natecoevo.nature.com shorturl.at/m2EOx

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...

Europe’s flora is living in a landscape out of Equilibrium
99% of plant distributions in Europe show signs of disequilibrium. The surprise? Climate change was only part of the story. Disturbance emerged as an even more pervasive force shaping where species oc...

Ok, I see your point now. I understand this is a wrong use of the word nutrient here to actually refer to communities that are richer in nitrogen-loving species. Sorry if we have used a bad wording in the title. Shame that we did not realise it. It was not intended

Jonathan Lenoir 🌳🌲🌴 @jonlen.bsky.social · 15/04/2026
The title does not say or even imply that we measured individual plant nutrients? We are clearly mentioning the community level of analysis. We basically showed how communities are getting enriched or not in plant species that love soil nitrogen, more open conditions, warmer conditions, etc.

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: ow.ly/Mokn50YCqty
Climate niche models correctly predicted the direction of some empirically documented range shifts for bird species in the genus Tyrannus.
