Research "Community Ecology & Ecotoxicology"

Topics

Our research is concerned with multiple stressors in agricultural landscapes and has a focus on the effects of pesticides on terrestrial biodiversity and communities. We study the interactions between species on different spatial and temporal scales and try to understand patterns such as variation in species richness, productivity and food web structure and processes of community assembly.

Ecotox

Additionally to known stressors such as habitat destruction or disease we consider pesticides effects to explain observed patterns and especially food web disruption gets our attention.
