🌸Plant diversity dynamics over space and time in a warming Arctic 🌸
Our new study @nature.com analysed plant diversity change in >2000 tundra plots over 4 decades. We found that plants changed unevenly, mostly driven by warming and biotic interactions.

In our new article led by Gabriele Midolo, published in Ecology Letters, we show that plant species richness in European plant communities generally decreased between the 1960s and 1980s. However, since the 1990s, this trend seems to have stopped or even reversed.

Why are some species widespread while others are found only in small, isolated areas? A study in Nature Communications shows that species with narrow ranges, and thus higher extinction risk, are often island-restricted, poor dispersers, and have evolved relatively recently. #evosky 🧪
