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.

Harms of introduced large herbivores outweigh benefits to native biodiversity - Nature Communications
Using impact assessment frameworks, this study shows that the introduction of large mammalian herbivores outside their native range has predominantly caused negative impacts on native biodiversity globally. The authors advise caution regarding their further intentional introduction for conservation purposes.

Plants cool the land through evapotranspiration, but green foliage can absorb more heat than lighter surfaces, causing warming. A study finds that in the northern hemisphere, cooling outweighs warming until the end of the growing season. In PNAS: www.pnas.org/doi/10.1073/...

Who said that biogeography is necessarily a correlative science? This is the way to do ecological experiments with a biogeographical perspective. Read this nice thread about a superb #functionalbiogeography work (spoiler: they find regional variations and habitat effects in antipredation traits)🧪🌐
