A Postdoctoral Fellowship is available for our NSF-funded investigation of sperm modification within the female reproductive tract. Molecular interactions between sperm and the female reproductive tract evolve across closely related species and may contribute to reproductive isolation. Sperm undergo numerous modifications as they move through the male and female reproductive tracts, although the nature of these interactions and their importance for fertilization success is not well understood. This project will characterize these changes at the molecular level, within closely-related species of fruit fly, as well as following hybrid inseminations, to understand their evolutionary history and influence on sperm survival and fertilization success.
