The department’s research activities involve terrestrial as well as marine environments, both locally and globally. Geographically, the Baltic region and the tropics are key areas. The research activities are conducted primarily in biodiversity, ecology, ecotoxicology, evolution, plant physiology and plant systematics. In these areas studies are performed on processes and patterns from molecular to ecosystem level, and interactions within and among species and with the environment and society. Several of our research areas are among those identified as strong within Stockholm University (climate, ocean, and environment) and the Faculty of Science (species interactions). Some of the research has direct environmental and societal relevance and the approach is often broad and interdisciplinary.
