Laboratory Induced Hybridization of Two Crayfish Species, Orconectes rusticus and O. propinquus

Journal of Crustacean Biology, 5(2):347-349.

Abstract

Laboratory induced interspecific copulations between the crayfish Orconectes rusticus and O. propinquus resulted in fewer broods and fewer Stage III juveniles per brood than did intraspecific copulations. Naturally occurring interspecific copulations should therefore affect the reproductive success of both species where they coexist, and may have contributed to the recent range expansion of O. rusticus.
