Research Interests

Parasitism is the most common lifestyle on earth and most organisms are effected by it. Parasitism is a fascinating and exceptionally successful life history strategy with often severe impact on the fitness of its host species. As a result many host species have developed defense mechanisms to limit the costs of parasitism. These traits, their evolution and potential tradeoffs involved in such defense are the main focus of my research.

PhD project

In my current research project I focus on the impact of parasites on their hosts behavior, physiology and population genetics. I have chosen Protomognathus americanus as the study system. P. americanus is an obligate social parasitic ant, parasitizing three species of the genus Temnothorax. These parasites lack the essential abilities to found and maintain a colony on their own, and thus rely on allospecific workers to raise their young and maintain their colony. P. americanus replenishes its slave worker force during regular and destructive raids. During these raiding events P. americanus steals the brood of neighboring host colonies often leads to the destruction of the attacked colony.

During my PhD I investigate different aspects of host defense of the main host species T. longispinosus. In particular I study the evolution and maintenance of a post enslavement defense trait termed “slave rebellion”. This particular trait of enslaved host workers results in low parasite survival due to killing and neglect of parasitic brood by host workers. It has been hypothized that enslaved host worker could not develop such behavior defense mechanisms as they do not reproduce in the field. We investigate if a kin selection could present a possible solution for this problem.
