Parthenogenesis (Virgin Reproduction), Hybridization, and Life History Plasticity in Mayflies

800 532 Stroud Water Research Center

Scientists are studying a number of mayfly species in White Clay Creek as well as in streams throughout eastern North America to better understand virgin reproduction and hybridization in mayflies, confirm the biological integrity of species that are genetically distinct but have the same name, and develop valuable laboratory techniques for mating and rearing aquatic insects.

The focus of this research on virgin reproduction and hybridization among mayfly species, which started in the 1980s, has been expanded beyond Centroptilum triangulifer and Centroptilum alamance to include a number of related and unrelated mayfly species in Pennsylvania’s White Clay Creek, as well as streams throughout eastern North America.
