The NRRV (English: River Ecology and Management, RivEM) research group conducts basic and applied research on aquatic ecosystems. We focus on fluvial systems, from small streams to large rivers, with a particular emphasis on solving real-world conservation problems. Recent large projects have focused on fish migration and fish passage, life-history research on migratory species, ecological connectivity and modelling, winter ecology and global climate change, forest-stream interactions and fish-mussel host-parasite systems. Our stream aquarium facility allows us to conduct basic research year-round, to link ecological theory to our applied research.

We are a core group of ten senior researchers, with a number of postdoctoral researchers and graduate students. We maintain an extensive international network, with collaborators throughout Europe, North America, and beyond. We also offer a Master of Science program with emphasis on ecology and conservation biology, accepting students each fall.
