I am interested in social life and all its fascinating aspects reaching from benefits that facilitated the evolution of group living to the molecular processes controlling the behavior of a single individual within a social structure. Whereas I focused on how animals outweigh the costs of associated with group living in my Bachelor and Master theses, I want to understand the (epi-)genetic basis of ant worker behavior during my PhD. The methods I used (or plan to use) to answer such questions include behavioral experiments, infections with different pathogens, immunological assays, transcriptomics, methylomics, bioinformatics and scripting, RNAi and quantitative PCR.
Division of labor is key to the ecological success of insect societies and fundamental to their social organization. In most social insects, behavioral and morphological castes are not genetically determined, but develop through phenotypic plasticity. Division of labor becomes more pronounced in larger colonies both within and between species. Moreover, behavior and task allocation typically changes in workers with age, a phenomenon known as polyethism.
This project aims at a deeper understanding of the evolution and ontogeny of division of labor in ants. We are interested in the identity, regulation and selection of genes, whose differential expression are important for the division of labor in workers. We will analyze how behavioral performance, epigenetic signature and gene expression patterns change over a workers’ life and which factors other than age influence worker behavior, such as morphology or experience. Our model species of the genus Temnothorax are characterized by small colonies, monomorphic, long-lived workers with a clear division of labor into different behavioral castes.
