Birgit Köhler

I am an environmental scientist focusing on ecosystem processes and functioning, and impacts of global change on those. I am currently working on large-scale biodiversity patterns and trends in coastal areas, offshore wind energy-related questions, aquatic food systems, and nature-inclusive design of artificial structures. Earlier work included research on carbon and nitrogen biogeochemistry and cycling in both forest and lake ecosystems. 

Examples of projects that I am currently involved in are linked to here below:

montane forest exposed to elevated nitrogen input"
10/1999 - 07/2005: Studies of Geoecology, University of Potsdam, Germany
