We put this out as a preprint so the community can help pressure-test it. If we missed your work, misinterpreted something, or if you have data that alters any conclusion, please tell us. This only gets better with more eyes on it!

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.

I'm preparing for my talk at #BES2025 and want to know what people think the main goal of applied ecological and conservation research is. If everything goes to plan, I’ll be using the poll results in the talk itself, so the more responses the better! @britishecologicalsociety.org
What do you think the primary goal of applied ecological/conservation research is?

Our latest study in Environmental DNA shows how fish daily vertical migrations affect eDNA in the ocean. 🐟
For species like European hake, seafloor eDNA signals vary between morning and evening, showing that behavior must be considered in eDNA monitoring.
