Research Interests

evolutionary genetics, evolutionary ecology, behavioural genetics  

I am interested in the adaptive potential of organisms to their environment. This may include abiotic factors, such as temperature, as well as biotic factors, such as the interplay within a social ant colony.  

 

Behavioural genetics

Social Hymenopterans feature a number of special traits, which clearly set them apart from all other animal groups. In ants, different worker castes and the queens develop from the same genetic background (polyphenism). In addition ant workers are further specialized on various tasks, from brood tending, over nest guarding to foraging. In some ant species behavioural caste differentiation is associated with morphological caste differentiation, however in other species monomorphic workers perform the different duties. I’m interested in the genetic mechanisms that lead to the development of the different castes as well as their differential behaviours. The genus Temnothorax is an ideal study system, as salvemakeing evolved several times independently, thus making it possible to investigate and compare the evolution of behavioural patterns in closely related species. In addition, the system allows to investigate co-evolutionary processes and local adaptation between closely related slavemaker and host species.  

 

Niche evolution

Closely related species, as well as different populations of one species, often occupy different niches and are thus adapted to different environmental properties. I’m interested in the adaptive potential of species to their environment, specifically to changing temperature and climate conditions. In this respect, a combinatory approach of studying both, proximate (phenotypic) as well as ultimate (genetic) traits is optimal. The combination of different methods (e.g. life-history trait determination, identification of selected genes) allows to draw conclusions on the proportion of phenotypic plasticity and evolutionary differentiation on the regulatory or structural level. As study organism I am working with the pond snail genus, Radix. Niche models have shown, that the distribution ranges between species (as well as populations) differ in temperature, as well as length of dry period.                             

Methods

common-garden-experiments, population genetics, Next Generation Sequencing (gene expression patterns, shot gun, RAD-tags), animal physiology, life-history data, behavioural observations.
