Abstract: | In this paper, we report the isolation of 11 polymorphic microsatellite loci from Lithophragma maximum (Saxifragaceae), a rare species restricted to San Clemente Island, California. We found moderate levels of allelic variation (mean NA= 5.5) and high levels of expected heterozygosity (mean HE= 0.531) across sampled individuals. However, eight loci showed a significant absence of heterozygous individuals, which we attribute to small population size and demographic history of the species. |
