Some weeks ago I submitted my first own research proposal. And now it got accepted! 😍 This means, @ecoresearchzoo3.bsky.social will go underground and start investigating the evolution of cave arthropods. So excited for this new chapter! 🦇 🪲🕷️

New study on arthropod declines @natecoevo.nature.com 🪲

In two time series @jena-experiment.bsky.social & @bexplo.bsky.social we show how community (dis)assembly underpins local biomass declines.

It mostly boils down to species loss, with identity losing relevance.

📢 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.
