Limited thermal tolerance in tropical insects and its genomic signature - Nature A survey of tropical insect populations and thermal tolerance limits indicates that species from lowland areas have low capacity to survive increased temperatures, and that thermal tolerance is limited by fundamental properties of protein architecture.

Dung beetles do not profit from enhanced spatial heterogeneity in temperate production forests: A forest manipulation experiment Our results suggest that dung beetles do not profit from management increasing the structural heterogeneity of production forests. Future warming and openings in forest structure might have negative ...

Seems like the findings of @johannaasch.bsky.social on #dungbeetle diversity well match to the temperature stress responses of the forest dung beetle to changing climates🌡🪲 Stay tuned for exciting further insights 🤩

New paper out in @jappliedecology.bsky.social! We investigated how forest structural heterogeneity and climate influence temperate dung beetles in production forests. 🪲

Ich durfte kürzlich ein bisschen über den tollen Waldmistkäfer erzählen und warum wir uns Sorgen um seine Zukunft machen 🪲

Anne Chao and @piambr.bsky.social, the 100% perfect dialogue duo at #gfoe2025! ✨
Thank you for sharing statistical insights on sample coverage and it's standardization in the first @gfoesoc.bsky.social keynote session using #BETAFOR data.🌳🌱

Looking forward to seeing all of you here! As an appetizer, here is part of what you will be able to enjoy next week:

Inconsistent short-term effects of enhanced structural complexity on soil microbial properties across German forests Structural and biotic homogenization can result from forestry practices lacking promotion of canopy gaps and deadwood. This can lead to biodiversity l…

New paper out! 📃 Enhanced structural complexity in forests has limited effects on #soil abiotic properties, but #microbial activity and biomass respond site-specifically. Soil moisture and understory growth link to microbial functions. 💧🧫🌳🍁

Congratulations to our colleague @sabinenooten.bsky.social from the Chemical Ecology group at @ecoresearchzoo3.bsky.social on receiving the Marcella Boveri Prize of the @uni-wuerzburg.de Biocenter, and on her great presentation of her work on insect #ecology and #biogeography

New research out from our PhD student Fabian Klimm!

Dung beetles also use other brooding strategies, apart from tunnelling. "Dwellers" brood their larvea inside of the dung and the famous "rollers" form dung balls and roll them away to a safe place.

Dung beetles 🪲 dig tunnels underneath the dung, where they bury brood balls for their larvea to feed on. This is great for the forest soil, since it improves fertilisation and aeration.

Have you ever wondered what happens when you put 400g of cow dung in the Bavarian Forest? - A feast! 🪲🪲

Insects are struggling with major global change drivers, like climate change and habitat loss. Researchers from @ecoresearchzoo3.bsky.social have now investigated, how these threats interact. The results show that bees suffer in particular. 🐝☀️🏙️

Had fun presenting my poster about the effects of climate and forest structure on dung beetles at #EGU2025. Thanks to everyone in the Forest Floor session for showing so much interest in my somewhat different research topic! 🌲🪲 @betafor.bsky.social

Find us at #EGU25, where our PhD student @johannaasch.bsky.social of @betafor.bsky.social will present her research on how climate and forest structure shape forest dung beetle communities 🌲🪲
