Summary

Data presented are 1.) the locations where Coastal Cactus Wren (Campylorhynchus brunneicapillus) genetic samples were collected in southern California, in 2011, 2012, and 2013; 2.) 2012 and 2013 survey results; 3.) the territory locations of all Cactus Wrens detected in 2011, 2012, and 2013 in Orange, Riverside, and San Diego counties; and 4.) dispersal results on a subset of Cactus Wrens color banded in 2011. These data support the following: Barr, K.R., Kus, B.E., Preston, K.L., Howell, S., Perkins, E. and Vandergast, A.G., 2015. Habitat fragmentation in coastal southern California disrupts genetic connectivity in the cactus wren (Campylorhynchus brunneicapillus). Molecular Ecology, 24(10), pp.2349-2363.

Purpose

The goal of this study was to evaluate the degree of genetic connectivity among coastal Cactus Wren populations in southern California. The research addressed a high priority need identified by the San Diego Management and Monitoring Program (SDMMP); specifically, how well are corridors serving physically and functionally to connect habitat patches and populations within networks of preserved sites, such as those protected under the San Diego Multiple Species Conservation Program and similar plans? Cactus Wren was ranked first among four top priority avian species identified by the SDMMP as requiring investigation regarding genetic connectivity. Our results provided information on Cactus Wren genetic variability and gene flow among populations that can be used to inform decisions regarding current and future corridor needs for maintaining viable Cactus Wren populations in coastal California. Specific objectives include: 1. Develop a minimum of 10 polymorphic microsatellite loci that amplify DNA from coastal Cactus Wrens. 2. Collect blood samples from Cactus Wren populations throughout southern California, and individually color band Cactus Wren nestlings at selected sites in San Diego County for a future investigation of juvenile dispersal (Objective 4). 3. Use microsatellite markers to evaluate within- and among- population genetic variability. 4. Conduct follow-up surveys to resight color banded wrens and evaluate dispersal patterns and behavior. We sampled populations from throughout the range of the Coastal Cactus Wren, including those in the vicinities of (from north to south): Ventura County, Palos Verdes Peninsula, Puente Hills/Chino Hills, San Dimas, Puente/Chino Hills, Redlands, southern and central Orange County, Marine Corps Base Camp Pendleton, Fallbrook Naval Weapons Station, Aguanga area in western Riverside County, San Pasqual Valley, Lake Jennings, Sweetwater/Encanto, and Otay Valley.
