As an ecologist I am interested in the relationship between anthropogenic effects and biodiversity. The increase of land use has a negative effect for biodiversity, ecological systems and response diversity (RD) but the basic mechanisms are still not properly understood. RD is the assumption for the resilience of an ecological system against disruption. The sensitivity of a system depends on the number of functionally related organisms in it, which respond differently to altered environmental conditions.
In this context I study the impact of land-use effects on moth diversity, trait composition and plasticity. I focus on the reaction of moth species on land-use activities (namely grazing, mowing and fertilization) in three different German exemplary large-scale and long-term research sites. I additionally analyse the response of live-history traits (e.g. feeding niche, size, hibernation) to land use and investigate the effects of different climatic conditions to moth species.
The study by which I intend to achieve my PhD belongs to the Biodiversity Exploratories, which is a part of a Science Foundation project funded by the German Research Foundation.
