Florian Altermatt and a slide with his proposed pipeline.

Fascinating an motivating plenary talk from @florianaltermatt.bsky.social at #DGL2025. He made a strong plea for rethinking the way we use eDNA to monitor aquatic biodiversity. Inspired me to read more about his research.

Clarifying the trophic state concept to advance macroscale freshwater science and management For over a century, ecologists have used the concept of trophic state (TS) to characterize an aquatic ecosystem's biological productivity. However, multiple TS classification schemes, each relying on...

The @ictc13.bsky.social keynote everyone was waiting for: Hans Paerl. He provided a truly global view, expanding our focus to coastal and marine systems. He stressed that sustainable control requires P and N reduction and that climate change, droughts, floods, and storms intensify our challenges.

The question was whether 'Planktothrix is in trouble', given that in recent years it has appeared in deeper layers below the euphotic depth. His explanation: lower P due to re-oligotrophication, so that P.r. is 'oversummering' in the hypolimnion and only growing in winter.
