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

Proceedings of the National Academy of Sciences@pnas.org · 4mo ago

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

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

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

#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...

After 4yr of hard work to compare empirical species range positions' shifts from the #BioShifts DB against predictions from niche-based models trained on climate & tailored to methodological attributes of each species & study, we found species shift ahead of models' predictions! 🦋 shorturl.at/vOmCw

Anticipating how species distributions will shift with climate change is key for biodiversity conservation and management. Commonly, species’ range...

Genetic diversity matters for species on the move in response to climate change ⬇️ We found that genetic diversity interacts w/ the velocity of climate change to explain the velocity at which species shift their range positions over time shorturl.at/682E3

Genetic Diversity Impacts Climate‐Induced Species Range Shifts

Genetic diversity may buffer species against climate-driven range contractions and facilitate expansions, but its role at a global scale remains unclear. Using 4673 range shift estimates for 1888 spe....

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/...
