I am studying Ecology and Biodiversity for my Master’s, and I am working on the invasion biology of two ant species from the genus Tetramorium.

For my thesis, I will analyze genetic data of the two closely related ant species Tetramorium immigrans and T. tsushimae, which are both invasive in the USA and have different social systems. I want to understand what strategies are responsible for invasive alien species to be so successful in non-native habitats and how they handle the loss of genetic diversity. An introduction event of one or few individuals is normally followed by inbreeding, which is generally thought to be disadvantageous for the viability of a population. Nevertheless, invasive species seem not to have problems with inbreeding depression. I want to find out how many introductions of these ant species happened and where they originated. Further, I want to know how their different social systems influence their population structure and the strategies resulting in successful invasions.


Research Topics:
