The Wirth-Weigelt Working Group
The Leipzig University - Systematic Botany and Functional Biodiversity Working Group. Asking questions about the causes and consequences of biodiversity!
- Meet Snowy, our newest team-member ⛄ Specialized in frozen systems, cold conditions, and standing very still. Performance strongly temperature-dependent. Will unfortunately leave the team as soon as spring arrives ❄️
- 🌱 Before the winter break, our research group had a tree-planting activity at the #ARBOfun research arboretum Großpösna, kindly supported by the Botanical Garden Oberholz and pupils from the Wilhelm-Wander School. A cold but great day for everyone! 🌳
- Reposted by The Wirth-Weigelt Working GroupJust before the Xmas break🎉 In @journalofecology.bsky.social and led by Anvar Sanaei, we provide insight into #trait coordination across 90 common and future European #tree species👇 doi.org/10.1111/1365... @agwirthweigelt.bsky.social @unileipzig.bsky.social @uni-freiburg.de
- 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
- A peek behind the scenes 🔬💧 PhD candidate Michele ter Huurne is extracting water from soil and twig samples to trace where trees get their water using δ18O isotopes. Huge thanks to Dr. Matthias Saurer @wslresearch.bsky.social for the guidance and lab support! #droughtresearch #biodiversity #forest
- Congratulations also to Dr. Ingmar Staude on this important contribution! The study highlights that ecological networks can adapt to shifting floras - a key insight for managing biodiversity change in a warming world. #biodiversity #research
- Big congrats on the publication, @lsachsenmaier.bsky.social 🌳🎉👏
- Science meets finance 🌱 At the event “Biodiversität – die unterschätzte Abhängigkeit” in Potsdam, organised by the Nord-Ostdeutsche Sparkassenakademie, Dr. Jori Marx presented insights from the #Faktencheck #Artenvielfalt and joined the panel discussion on how the financial sector depends on nature.
- Scenes from the @treedi.bsky.social conference 🌳 Participants joined Prof. Christian Wirth for a guided tour through the ARBOFun arboretum - exploring how long-term measurements help us understand forest dynamics and tree functioning #treeDi #ForestEcology #PlantScience

- 🌱 #Fieldwork days at The Jena Experiment - @jena-experiment.bsky.social! Scanning roots with a minirhizotron, tracking seasonal changes & traits, plus plant surveys & soil checks. Led by PhD candidate Srijna Saxena with support from Tom Künne. Can’t wait to see what the data reveal! #RootTraits
- Back in the floodplain forest 🌳 We’re monitoring oak regeneration under different conditions. These seedlings are part of an experiment to better understand forest dynamics in changing environments. #Quercus #Leipzig #Floodplainforest #Oak #Regeneration 📍 Leipzig Auwald
- 📊 „Faktencheck Artenvielfalt“ is the first comprehensive report to show the actual state of biodiversity in Germany🌿. The full report has now been published in English! 📥Download for free here: www.feda.bio/faktencheck-en. Watch the full video: tinyurl.com/mps5vfhf #Biodiversity #research #factcheck
- Very cool to see this coming together! 🌲🔬 Sampling from 12 conifer species at #ARBOfun – part of our trait campaign @idiv-research.bsky.social We are curious to see what stomata can tell us about drought responses! #conifers #stomataltraits #fieldtolab
- Root shrinkage measurements of 40 #tree species at #ARBOfun completed! We've measured root #shrinkage, to understand #root-soil contact under #drought. The campaign was led by Dr. Anvar Sanaei with great support of our technician Nicole Nabel. Excited to see the results! #RootTraits #PlantScience

- 🌿 "Biodiversity can help protect the climate," says Christian Wirth at #DKK2025. Reaching the 30% GBF conservation target is key – but the remaining 70% of land also needs more biodiversity to fight climate change. 🔗 www.deutsches-klima-konsortium.de/news/pressem...
