The Jena Experiment

@jena-experiment.bsky.social

One of the longest-running grassland biodiversity experiments worldwide (since 2002). Uncovering the mechanisms that drive biodiversity-ecosystem functioning (BEF) relationships over time. https://the-jena-experiment.de Funding: @dfgpublic.bsky.social

🌐📏🧪🌱 New research synthesizing data from our experiment and many others finds stronger biodiversity effects on functioning under drought & aridity in grasslands than forests 👇

One more piece of evidence, on a growing pile, that insects are in decline. "...the general species turnover and biomass trends emphasize ongoing arthropod community simplification, and that even common species may be increasingly under threat." 🪲🪳🧪🌍 www.nature.com/articles/s41...

Arthropod species loss underpins biomass declines - Nature Ecology & Evolution

Insects are declining in many regions. Here the authors show that arthropod biomass losses in Jena Experiment and Biodiversity Exploratories time series are driven more by species loss than by species...

📢 Over 90% of local insect biomass decline in German grasslands is explained by species loss. “By the end of the study period, species loss, regardless of rarity or size, had become the main driver of decline”, says @bmwildermuth.bsky.social of #iDiv and @uni-jena.de www.idiv.de/majority-of-...

Majority of local insect biomass decline linked to species loss

A new study shows that over 90% of insect biomass declines are driven by shrinking species numbers, posing a risk to ecosystem function.

New paper from our JenaTron facility: Bröcher et al. show that reciprocal effects between plants and invertebrate herbivores vary with plant species richness, plant history and soil history. Herbivores want nutritious plants with soil history, while they reduce plant height in monocultures 🐛🌱
