Dynamics of ecosystems
The main focus of research in the malacological department is in the field of evolutionary systematics. We investigate evolutionary processes such as speciation, radiation and hybridisation using a combination of morphological and molecular genetic methods. Depending on the objective of the project, the systematic, phylogenetic and population genetic findings are linked with geographical and ecological data in order to better understand the processes that have led to the development of the observed biogeographical and macroecological patterns and thus the dynamics of ecosystems.
Land snails as model organisms
We use land snails as model organisms for our studies. Due to their low mobility, land snails are not only a suitable model group for analysing historical processes, but they are also suitable as indicators for the quality of habitats and are therefore relevant for nature conservation purposes.
