We, Natalie and Yvonne, are launching this collaborative network to advance the use of environmental DNA (eDNA) in hydrology and geosciences. Our mission is to bridge the gap between geoscientists and biologists, fostering interdisciplinary collaboration to advance research and understanding of aquatic and terrestrial ecosystems.

By connecting experts across fields, we aim to explore innovative approaches to explore how eDNA can be used as a powerful tracer for understanding water movement, flow pathways, and interactions within aquatic systems. But also to incorporate hydrological aspects into monitoring biodiversity, tracking ecosystem changes, and understanding the complex interactions between organisms and their environments.

Through the sessions, courses, and meetings we convened, we engaged geoscientists and biologists in cross‑disciplinary dialogue about how to adapt and apply eDNA methods as tracers for flow pathways, mixing, transport, and water connectivity in natural and engineered aquatic systems. This experience shaped our network’s core aim: to foster methodological innovation and build a collaborative community that embeds eDNA‑based tracing into hydrology and geosciences.

We envision our network as a catalyst: combining the strengths of biological and geoscientific expertise, facilitating training, and promoting collaborative research that addresses pressing water‑related challenges in a changing environment.

Our network provides a platform for researchers to exchange knowledge, develop new methodologies, and jointly design studies that integrate hydrology, geoscience, and molecular approaches. By bridging disciplinary boundaries, we enable a more comprehensive understanding of water dynamics, flow connectivity, sediment transport, and subsurface–surface water interactions — using eDNA to complement traditional hydrological tools.

We believe that the future of environmental research lies in collaboration, and through this network, we hope to empower scientists to address the pressing ecological and hydrological challenges of our time. By connecting experts across disciplines, we aim to foster innovative research, share methodologies, and develop new tools to track and study hydrological processes in natural and engineered environments.

Our network serves as a platform for knowledge sharing, joint research initiatives, and the integration of cutting-edge eDNA methodologies into hydrological and geoscientific studies.
