The molecular basis of sperm competition. This project aims to unravel the molecular basis of reproductive conflicts. Males compete for paternity and this continues after mating if females copulate and receive semen from multiple males. In ants and bees, molecules in males’ ejaculates recognise and kill rival males’ sperm. Reproductive proteins in leaf cutter ants’ seminal fluid may be the molecular agents of sperm competition. This project will investigate reproductive proteins and their functi ....The molecular basis of sperm competition. This project aims to unravel the molecular basis of reproductive conflicts. Males compete for paternity and this continues after mating if females copulate and receive semen from multiple males. In ants and bees, molecules in males’ ejaculates recognise and kill rival males’ sperm. Reproductive proteins in leaf cutter ants’ seminal fluid may be the molecular agents of sperm competition. This project will investigate reproductive proteins and their functioning and effects on reproductive success. This project will show how reproductive conflicts over paternity operate on the protein level and may lead to novel avenues for future pest control.Read moreRead less
Evolutionary proteomics of social insects. This project aims to understand the molecular mechanisms that affect fertility in honeybees and leaf-cutting ants by identifying the function of proteins in male and female secretions related to insemination and sperm storage. The understanding of these general principles will have important applications for honeybee breeding.
