IQ-Wasser funded by Federal Ministry of Education and Research (BMBF) Exploring the use of AI in water monitoring
[28-01-2025] Biodiversity and water quality are strongly interconnected. The newly funded IQ-Wasser: KI & Biodiversität project will link artificial intelligence (AI) alghorithms to predict biodiversity changes in riverdam-mediated drinking water reservoirs in Germany to evaluate the effects on drinking water quality. As leader of the subproject Microbial diversity and ecology, Julia Nuy from our lab is contributing to this groundbreaking initiative disclosing ecosystem functions and pathogenicty potential of the microbial community.

"Environmental Metagenomics" receives the ERC Synergy Award 11.5 million euros for research into the microbial carbon cycle
[26.10.2023] A research team from the Universities of Münster, Bremen, Duisburg-Essen and the German Research Centre for Geosciences (GFZ) in Potsdam has been awarded prestigious funding from the European Research Council (ERC): an "ERC Synergy Grant" worth a total of 11.5 million euros. In the six-year "Archean Park" project, the scientists want to gain insights into life under primitive conditions and find previously unknown metabolic pathways that made life possible for microorganisms on the primordial Earth 4,000 to 2,500 million years ago. 2.56 million euros of the funding will go to the UDE.

Pubication in Nature Microbiology A predicted CRISPR-mediated symbiosis between uncultivated archaea
[27-07-2023] A new study in Nature Microbiology uncovers an unexpected role of CRISPR–Cas systems in archaea, showing that these defense mechanisms can target chromosomal DNA of their own episymbionts. Using meta-omics from extreme environments, researchers found that widespread DPANN archaea use CRISPR to regulate essential genes in their symbiotic partners, suggesting a dynamic relationship that shifts between parasitism and mutualism. This discovery reshapes our understanding of host-symbiont interactions in microbial ecosystems

Research Projects

CRC 1439 Multilevel response to stressor increase and release in stream ecosystems
Project A01
Direct and indirect effects of multiple stressors in freshwater ecosystems on microbial parasites and scavengers
Freshwater ecosystems can be exposed to multiple stressors over time, some of them being imposed due to natural (e.g. seasonal) fluctuations, others due to human activity. While the effects of stressors on microbial community composition has been investigated for several freshwater ecosystems, the resulting impacts on microbial interactions including virus-host dynamics remains unexplored. Here, we propose to investigate the dynamics and interactions of microbial parasites, including viruses and microbial scavengers, and their potential hosts when exposed to multiple stressors in freshwater systems.

Project Z-INF
Data management and integration
The Z-INF project represents the backbone for data management and data integration to facilitate collaboration inside RESIST. Data storage and data exchange between RESIST’s individual projects and with external institutions will be coordinated by Z-INF, for which a respective infrastructure will be established. Central data storage facilities will ensure archiving and accessibility of raw and processed data of RESIST. Management of research data for exchange between projects, for publications and future internal and external use will be provided and maintained.

Proposed Cluster of Excellence REASONS: River ecosystems in the Anthropocene
Rising temperatures, antibiotic residues, droughts and flooding: worldwide, rivers are increasingly under pressure. To prepare them for the challenges of the future, researchers from the proposed Cluster of Excellence REASONS are developing a new, sustainable concept for the management of freshwater ecosystems.
