Six Decades of Losses and Gains in Alpha Diversity of European Plant Communities
We developed a new method based on machine learning to interpolate spatiotemporal trends in vascular plant diversity across Europe from 1960 to 2020, utilising vegetation data without temporal replic...

Terrifying!
Check out our new insect decline paper. By analysing 36 yrs of German ground beetle distribution data, we show:
- ~80% of species have declined, with significant declines for >50%.
- The decline was similar across species traits and threatened status.

“Since ground beetles are key predators in many natural and agricultural ecosystems that play an important role in pest control and the food chain, their decline should raise concerns.”

A study published in Nature Climate Change analyses net primary production (NPP) trends from 2003 to 2021, revealing an overall increase in planetary NPP, primarily due to terrestrial enhancements despite a decline in oceanic productivity. go.nature.com/4fP7uBA 🧪
Contrasting biological production trends over land and ocean - Nature Climate Change
The authors jointly assess the changes in land and ocean net primary production from 2003 to 2021. They show contrasting trends, with overall planetary increases (0.11 ± 0.13 PgC yr−1) driven by terrestrial enhancement and offset by oceanic decline.
