The Emschergenossenschaft and the NABU NRW invited researchers to the First Day of the living Emscher. The set goal was to record the diversity of species in the new mouth area of the once most polluted river in Germany. The TrendDNA-Team of the University of Duisburg-Essen took part in the event. Robin Schütz and Florian Leese, as well as Till-Hendrik Macher (GeDNA-Project) analyzed traces of animal species from environmental DNA in the water. Using a portable DNA-sequencing system, processing of the samples happened in the field. Identification through environmental DNA helped to discover numerous fish species, among others the eel and the ninespine stickleback.

TrendDNA participants Jan Koschorreck (UBA), Henrik Krehenwinkel, Julian Hans and Isa Junk (Universität Trier), Robin Schütz (Universität Duisburg-Essen), and Bernd Göckener (Fraunhofer IME) give a progress report and project outlook at the UPB Jahrestagung in Berlin.

Exciting new data from TrendDNA are presented at the 3rd Global Soil Biodiversity Conference in Dublin, Ireland. Here, Masters student Judith Paetsch (Senckenberg Gesellschaft, LOEWE-Zentrum-TBG) shows the lastest results of her project
using shotgun metagenomics to characterize the biodiversity of soil communities across space and time.
Our study on arthropod biomonitoring using eDNA from tree leaves is now published open-access in eLife! In this innovative study led by Prof. Henrik Krehenwinkel of Universität Trier, UPB samples were used to measure trends in diversity and relative biomass of canopy arthropods over a 30-year period. While species richness remained relatively stable at individual sites, the species composition changed drastically, resulting in an overall homogenization of forest arthropod communities across Germany.

TrendDNA members gather at the Fraunhofer IME for a thought-provoking discussion of possible future research directions and a tour of the Specimen Bank:
27-28 September 2022, University of Duisburg-Essen
PhD students Robin Schütz (Universität Duisburg-Essen) and Isabelle Junk (Universität Trier) present posters of their research showing the exciting potential for eDNA metabarcoding of suspended particulate matter and mussels to reveal changes in limnic and marine communities over time:
A companion project to TrendDNA is funded by the Bauer-Stiftung zur Förderung von Wissenschaft und Forschung. Led by Dr. Susan Kennedy, Prof. Henrik Krehenwinkel and Prof. Christoph Emmerling (Universität Trier), and in collaboration with Prof. Florian Leese (Universität Duisburg Essen), Prof. Miklós Bálint (Senckenberg TBG Frankfurt) and Prof. Thomas Udelhoven (Universität Trier), this exciting project uses metabarcoding, metagenomics and metatranscriptomics of earthworms to reveal changes in soil communities over time and across geographic distances.
