Molecular Ecology

topics: Ecology – Evolution – Conservation Biology

 

Molecular Ecology is an interdisciplinary research field in which different kinds of molecular markers and approaches are used to address questions in modern ecology, evolution, behaviour and conservation biology. Molecular ecology is strongly influenced by concepts of population biology as well as systematic and evolutionary genetics.

The research in our group focuses on organismic biology (zoology) and uses amphibians and reptiles as study organisms. We are applying a broad range of methodological approaches, ranging from the development of molecular markers to the application of cutting edge genomic approaches but also behavioural and ecological experiments. We are mainly interested in how organisms adapt to different and changing environmental conditions and how this can influence population differentiation and speciation. In this context, we are studying ecological and behavioural adaptations. Other important fields of research include conservation biology and the study of emerging infectious diseases in amphibians.

Currently, the main study organisms in our group are fire salamanders and Galápagos marine iguanas. For the fire salamander we have been able to develop over the last years a promising system to study processes and mechanisms of ecological speciation under natural conditions. Marine iguanas on the Galápagos islands offer a unique system to study processes of local adaptation and speciation in the worlds’ only sea-going lizard.
