My current research focuses on the evolution of ecophysiological adaptations to climate in lizards (e.g. Lacertidae) as well as in general on the biogeography and systematics of reptiles and amphibians. These two ectothermic animal groups are threatened by a global increase in temperature and changes in precipitation patterns, but the complex interactions of distribution range/population persistence, local climate and ecophysiological adaptation are still poorly understood.
Based on the latest genetic and genomic phylogenetic trees, the project in collaboration with MfN colleagues and external collaborators tries to shed light on reptile’s adaptation to climate using experimental designs to determine species-specific evaporative water loss rates and thermal preferences under consideration of the species’ ecology and distribution ranges. We use state of the art methods in the field of genetics and genomics, modelling approaches as well as the latest methods in our experiments and field studies.
Expeditions and future projects
At the end of 2018, I and colleagues from the US and South Africa will once again travel to the Kalahari to gather more climate data and genetic material and increase our data sampling to tackle lizards’ adaptation to climate. A future project will focus on the genomic basis and responsible genes for the experimentally determined adaptations of lizards.
