Cactus Wren Genetic Study - San Diego and Orange County

Project description

In this study, we describe genetic connectivity in the coastal cactus wren in San Diego County. To gain a broader perspective, we also obtained samples from the Nature Reserve of orange County, where many of the remaining coastal cactus wrens are found in that county. These data provide excellent resolution for describing current population structure in the species, reveal the gene flow regime, and provide insight on current levels of genetic diversity within populations, Understanding these patterns will aid in management of current coastal cactus wrens populations and future efforts in habitat restoration,
