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!

How will biodiversity respond to efforts to mitigate C emissions? Smith et al. in @science.org document that vert. biodiv. benefits from (natural) reforestation. BUT, planting biocrops, while it reduces climate change, hurts most species bc they lose habitat. 🧪🌎

Rapid rise in atmospheric #CO2 marked the end of the Late #Palaeozoic Ice Age

Jurikova et al. 👉 rdcu.be/d7fQJ

"About 294 million years ago, atmospheric CO2 rose abruptly (4-fold), releasing the Earth from its penultimate ice age and transforming the Early Permian into a warmer world."
