Isolation and characterization of ten microsatellite loci in Blue-footed (Sula nebouxii) and Peruvian Boobies (Sula variegata)

Ten microsatellite loci were isolated and characterized from Blue-footed (Sula nebouxii) and Peruvian Boobies (S. variegata). The loci were screened in 24 Blue-footed Boobies and 27 Peruvian Boobies: 8 were polymorphic in Blue-footed Boobies with between 2 and 10 alleles per locus and 9 were polymorphic in Peruvian Boobies with between 2 and 12 alleles per locus. Observed heterozygosity ranged from 0.29 to 0.84. These loci were also tested in Brown Boobies (S. leucogaster) and were variably polymorphic. These new loci are currently being used to assess population genetic structure in Blue-footed and Peruvian Boobies and will also be used to examine hybridization between the species.
