🌸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.

New study out in Ecology Letters 🌱🐑!
Using long-term Åland monitoring data, we found that herbivory increases plant diversity across scales and flips the diversity–area relationship: a positive relationship is found in grazed sites while a negative one in ungrazed sites.

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.
