First post on Bluesky! 🌿
Excited to share our new study in Ecography, led by Maxime Lenormand: combining naturalist inventories and satellite data to map plant biodiversity.
Here’s a bioregionalization of the flora of France!

Latest video is on niche differentiation and waterfowl. Why surface feeding and diving ducks look and fly differently, why pintail look elegant, why gadwall are mean to coot, why shoveler feed together and how pochard and tufted diets differ completely. youtu.be/-Aymrp9mr4E?...

Our newest paper led by Julián Tijerín-Triviño finds that #climatechange is slowing the productivity of European #forests: onlinelibrary.wiley.com/doi/10.1111/geb.70011

A 🧵:
We used 3 surveys over 15-30 years from >13,900 NFI plots in Mediterranean, temperate and boreal regions (1/5)
Forest Productivity Decreases in Response to Recent Changes in Vegetation Structure and Climate in the Latitudinal Extremes of the European Continent
Aim Climate change is driving increasingly frequent and intense extreme climatic events, pushing many forests worldwide beyond their physiological thresholds. Despite the major role played by forest...

The #EU Deforestation & Forest Degradation Regulation is due to come into force in 2026. It will ban products made using raw materials from deforested areas on the EU market.
To this end, research needs to come up with indicators to differentiate between preserved & degraded forests.

🌳One way of combating #deforestation is to define zones at particular risk. The difficult part is identifying those zones.
