Graduate position: PhD Position (w/m/d, 65 %, EG 13 TV-L, 3 years) Transcriptional Regulation in Beetle Sociality Senckenberg Biodiversity and Climate Research Institute, Frankfurt, Germany. Collaboration with Bayreuth University, Freiburg University, LMU München and Coventry University. PROJECT DESCRIPTION Subsociality is widely considered a prerequisite for the evolution of eusociality, as it introduces key behaviours, such as parental care and prolonged parent-offspring interactions, that can be co-opted and elaborated upon to form more complex social systems. Recently, we have been investigating the genomic basis of subsociality in 20 species of two distantly related beetle families, the weevils (Curculionidae) and carrion beetles (Staphylinidae: Silphinae), with varying degrees of sociality. Our comparative genomics analyses revealed convergent gene losses and a relaxation of selection with the onset of offspring attendance. Gene expression analyses reveal that the switch from the non-caring phase to pre-hatching care behaviour results in the strongest change in gene expression across species. Interestingly, both the genomic and transcriptomic analyses identifed gene regulatory mechanisms as being most strongly associated with social behaviour. We now plan to identify gene regulatory mechanisms involved in the differences and changes in gene expression associated with parental care and thus the onset of sociality. The accompanying project in München and Coventry will conduct a genome-wide screen for patterns associated with sociality using state-of-the-art machine learning approaches, and develop stochastic models to infer the importance of regulatory mechanisms. This project will thus shed light on the evolution of mechanisms involved in the transition from solitary to social life in insects. We are looking for a highly motivated PhD candidate with interest in molecular evolution, genomics, epigenetics, and behavior to identify key regulators and epigenetic modifications shaping the evolution of social behavior using a multi-omics approach.
