Applying SNP-derived molecular coancestry estimates to captive breeding programsIvy, Jamie A.; Putnam, Andrea S.; Navarro, Asako Y.; Gurr, Jessica; Ryder, Oliver A. (2016)...Although pedigree-based breeding strategies are quite effective at retaining long-term genetic variation, management of zoo-based breeding programs continues to be hampered when pedigrees are poorly known. The objective of this study was to evaluate 2 options for generating single nucleotide polymorphism (SNP) data to resolve unknown relationships within captive breeding programs...
Fitness costs associated with ancestry to isolated populations of an endangered speciesWilder, Aryn P.; Navarro, Asako Y.; King, Shauna N. D.; Miller, William B.; Thomas, Steven M.; Steiner, Cynthia C.; Ryder, Oliver A.; Shier, Debra M. (2020)... The endangered Pacific pocket mouse (Perognathus longimembris pacificus) persists in three isolated populations in southern California. Mitochondrial and microsatellite data indicated that effective population sizes were extremely small (Ne< 50), and continued declines prompted a conservation breeding program founded by individuals from each population....
Genetic population structure of Peninsular bighorn sheep (Ovis canadensis nelsoni) indicates substantial gene flow across US–Mexico borderBuchalski, Michael R.; Navarro, Asako Y.; Boyce, Walter M.; Winston, Vickers T.; Tobler, Mathias W.; Nordstrom, Lisa A.; García, Jorge Alaníz; Gille, Daphne A.; Penedo, Maria Cecilia T.; Ryder, Oliver A.; et al. (2015)…Within the United States (US), Peninsular bighorn sheep (Ovis canadensis nelsoni, PBS) are listed as federally endangered…. Patterns of genetic spatial structure indicate gene flow throughout the ranges is common, and construction of a US–Mexico border fence or wind energy infrastructure would disrupt connectivity of the metapopulation….
