Retreat time! In the great setting of the Austrian Alps we just started our group retreat to discuss science, new ideas & how to further develop our @globalchangeeco.bsky.social ecosystem. Here @christianzehner.bsky.social is kicking off the program with his project on occurrence sampling biases.

Deer browsing limits forest diversity – even in the light. New study in @jappliedecology.bsky.social by Würzburg ecologists and others: Even sunny canopy gaps cannot offset the impact of roe deer on forest regeneration. 🦌🌳☀️

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.

To minimise risk of infection, carpenter #ants resort to drastic measures: they amputate injured legs immediately. “Better safe than sorry” – the pragmatic approach proved effective, with survival rates of injured workers more than doubling. Study by @etf1989.bsky.social in @royalsociety.org

Reducing land use (single late #mowing) increased #insects by +41% after 1 yr and +99% after 3 yrs.
Species diversity, however, remained unchanged.

Why are we losing arthropod biomass? Because we're losing species? Because of which species we lose? Or because of declining abundances?
