Abstract
The endemic and endangered Hawaiian petrel (Pterodroma sandwichensis) breeds on four of the Hawaiian Islands, however the levels of gene flow between islands remain unclear. We describe 10 novel polymorphic microsatellite loci isolated from this species, and characterize 10 additional previously published primer sets in 40 individuals from the island of Maui. Loci exhibited between 3 and 14 alleles (mean 6.85), and observed heterozygosity ranged from 0.150 to 0.825 (mean 0.540). Four loci showed evidence for null alleles, although only one locus had significant deviation from Hardy–Weinberg equilibrium after Bonferonni correction. Two primer pairs showed significant gametic disequilibrium. The loci described here should provide a useful toolset for investigations of population connectivity.
