Applied and Trophic Ecology
Our work addresses the ecology of animals in natural and managed ecosystems and the role these organisms play in providing ecosystem services. We seek to understand mechanisms governing the structure and functioning of natural communities through integration of molecular techniques and stable isotope analysis with laboratory and field experiments. A major objective is the analysis of food web interactions. Current work explores, for example, food web structure and dynamics in pioneer communities within Alpine glacier forelands or how generalist predators respond to invasive earthworms. Other work addresses how plant diversity affects the dietary choices of soil-dwelling insect pests in Central Europe or whether the roots of exotic grasses sustain the larvae of endangered moths in Australia. DNA-based techniques also provide a powerful means to identify soil invertebrates, the basis to answer questions on biodiversity/species-identity effects for soil formation or plant protection. Our research is embedded in collaborative projects with scientists from several European countries, the USA, Peru, Nepal and Australia.
