![]() Since that time, the pocket gopher hybrid zone has stabilized, whereas the northern chewing louse species has replaced the southern louse species at a consistent rate of ~150 m/year. ![]() ![]() Flood control measures completed in the 1930s permitted contact, thus establishing the hybrid zone between the pocket gophers and the contact zone between their lice (without hybridization). Historically, the natural flood cycle of the Rio Grande prevented contact between the two subspecies of pocket gophers. We synthesize observations from 1979 to 2016 of a contact zone involving two subspecies of pocket gophers ( Thomomys bottae connectens and T. b. opulentus) and their respective chewing lice ( Geomydoecus aurei and G. centralis) along the Río Grande Valley in New Mexico, U.S.A., to test predictions about the dynamics of the zone.
