Limnology is the study of inland water ecosystems, including interactions of communities and populations, organisms ranging from microorganisms to predatory fish and the biogeochemical cycling of nutrients. Our research includes fundamental scientific questions, as well as applied topics of concern for the protection and management of the environment. The department includes three major research groups, which have a considerable amount of synergy and cooperation between them:
Norr Malma field station with the Erken Laboratory makes part of the Department of Limnology. It has since its foundation in the 1940s served both as a research station and as a study and course centre. During the early years, activities were mostly restricted to the summer season. Today, courses and other activities take place all year round. The Erken laboratory has developed an extensive environmental monitoring program for Lake Erken, and it is one of the sites in GLEON, the Global Lake Ecological Observatory Network. Researchers at Erken Laboratory participate in several large EU projects such as on the effects of climate change on lake ecosystems and automatic monitoring of phytoplankton development.
