Environments around the world are changing rapidly because of human activities. We investigate how organisms respond to these changes, and the consequences their responses have for populations, communities and ecosystems.

We have two main lines of research: one that focusses on empirical research and assesses how organisms respond to ongoing human-induced changes, such as climate change, eutrophication and light pollution, and another line that centres on synthesising the research field through reviews and the building of conceptual frameworks.

Our topics

Empirical research on responses to rapid environmental change

How do organisms respond to human-induced disturbances, such as climate change, eutrophication, and light pollution? Are the responses adaptive and promote population growth, or do they increase the risk of decline and possible extinction? Moreover, how do the responses influence other species and thereby the composition of the community and ecological processes?

These questions are investigated using a range of organisms, from small aquatic invertebrates in Nordic streams to large crocodiles in Indian rivers.


  • Effects of climate change and eutrophication on the species community of coastal waters in the Baltic Sea
  • Effects of light pollution on glow-worm reproduction
  • Effects of light pollution on gammarids and their ecological function in streams
  • Effects of light pollution on threatened species of the Ganga river system in India

Synthesising the research field

The amount of data on effects of human activities on organisms is rapidly growing, making it possible to search for trends, evaluate possible mechanisms behind the trends, and infer likely consequences of the responses for populations, communities and ecosystems. Thus, an important component of our research is to synthesise the available information and touse it to develop conceptual frameworks, identify future avenues for research, and provide information useful for decision makers in policy and management.
