A busy and inspiring #CBC2026 for our group last week 🌿 We contributed across the programme, with talks & posters by PhD candidates Srijna Saxena and Annalena Lenk, Dr Anvar Sanaei & others, and hosted an excursion to the Leipzig floodplain forest and our canopy crane. Great exchange!

New paper out, on a grassland experiment in which we manipulated plant alpha and beta diversity, and found that both affect plant productivity: esajournals.onlinelibrary.wiley.com/doi/10.1002/.... Thanks to @henneckejustus.bsky.social @agwirthweigelt.bsky.social Katie Barry and Lea von Sivers.

Congrats to David Schellenberger Costa, Martin Freiberg and Christian Wirth! The study shows how body size, habitat, range and even author numbers shape taxonomic description curves — and why estimating true diversity needs more than classic curve fitting! #Biodiversity #Taxonomy
