#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...

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...

Using numerous (n = 57390) & long, up to 100 yrs, time series of vegetation resurveys, from the #ReSurveyEurope database, we found local species richness (alpha-diversity) to increase by 0.2% per yr, associated with gains in functional & phylogenetic diversity ⬇️ shorturl.at/xuE9w

The #BioShifts working group made it to Science & Vie 🤩 I used to read this French scientific outreach magazine back in the late 1990's 😍 My teenager me couldn't imagine that 😅 I am so proud for the #BioShifts team 🌳🌲🌴🪻🐸🦋🪸🐠 Our research funding body #FRB will also be happy 😁 @frbiodiv.bsky.social
I am so proud of this paper ⬇️ recently published in PNAS 🤩 Four years in the making and countless computing hours to get bioclimatic velocities from species distribution models #SDMs that were tailored to each species and study from which we extracted empirical estimates of species range shift rates
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
