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...

Losses and gains in European plant communities. A fascinating but complex paper showing some good news i think onlinelibrary.wiley.com/doi/10.1111/...

Thanks, Fabian. It's unfortunate that we missed your data. Aletta might have some additional ideas, so please feel free to email her. I left Germany a few months after the meeting.

Terrifying!

Thanks to the amazing collaborators. Diana, Estève, Ortwin, Helge, Jörn, Thore, Jörg, Volker, Stephan, Ingmar, Florian, Reinhard, Roel, Marten, @alettabonn.bsky.social @idiv-research.bsky.social @monashbiol.bsky.social @monashscience.bsky.social

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.

Good question, but we didn't test the responsible driver.

“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.”

🚨New study led by @shawan-chowdhury.bsky.social calls for urgent systematic #insects monitoring.

🐞 Over 36 years of data reveal alarming declines in German #groundbeetles: 52% of species decreased in #occupancy, including many key #predators vital for #ecosystem balance.

🚨Job Alert!! Assistant professor vacancy ‘plant abiotic stress resilience’ in our group @uuplants.bsky.social Come for the science, stay for the amazing colleagues 😀More details here www.uu.nl/en/organisat... Please share!!

The defensive function of mutualistic ants for the Reverdin's Blue butterfly against two groups of parasitoids (tachinid flies and mermithid nematodes) differs among ant species, and this is affected by the number of precipitation days in the larval period of the butterfly. Camponotus japonicus is the most effective against flies, while Lasius japonicus against nematodes. The effect of rainfall is negative for fly parasitism but positive for nematode parasitism. Note that darker blue circles in the triangle indicate lower AIC values.

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.

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 🧪

This new paper documents a tenfold increase in research papers using community-collected iNaturalist data over just five years: tr.ee/89Ot3I

According to the study, here are four key ways that iNaturalist data directly powers science 🧵⤵️

iNaturalist accelerates biodiversity research Abstract. Participatory citizen science is expanding, with iNaturalist emerging as one of the most widely used platforms globally. However, its application

Brittany Mason and co-authors provide a snapshot of current iNaturalist data use, highlighting its taxonomic and geographic breadth and its growing impact on biodiversity research.
