Species distribution models predict genetic isolation of Hagen in Selys, 1853 (Odonata, Calopterygidae).

Understanding how past and current environmental conditions shape the demographic and genetic distributions of organisms facilitates our predictions of how future environmental patterns may affect populations. The Canyon Rubyspot damselfly (Odonata: Zygoptera: ) is an insect with a range distribution from Colombia to the arid southwestern United States, where it inhabits shaded mountain streams in the arid southwestern United States. Past spatial fragmentation of habitat and limited dispersal capacity of may cause population isolation and genetic differentiation, and projected climate change may exacerbate isolation by further restricting the species' distribution.
