Dr Fetzer had a background in ecology, with a main emphasis on aquatic ecosystems. He has vast experience in analyses of aquatic systems dynamics and application of statistics to determine the main environmental factors shaping existing communities.
His main research interests concern the importance of trait and species biodiversity and how the interactions between them shape and maintain networks between communities. He is also interested in how structural characteristics help to maintain resilience and resistance towards disturbances.
Currently he is working as a scientific researcher at the SRC. For the future he would like to integrate experimental work on communities with ecological theories, with special emphasis understanding non-linear regime shifts and alternative stable states.
