Microsatellite markers for the Common ringtail possum (Pseudocheirus peregrinus) and their amplification in other Pseudocheirids

Abstract

Eleven microsatellite markers were developed for the Common ringtail possum, an arboreal marsupial abundant in fragmented forests of south-eastern Australia. Loci were highly polymorphic (4-32 alleles per locus) and heterozygosity ranged from 0.66 to 1. Two loci deviated significantly from Hardy-Weinberg equilibrium proportions, possibly because of low-frequency null alleles. These markers will be informative for examining patterns of gene flow, relatedness and mating systems within fragmented populations of the Common ringtail possum and have potential for use in other Pseudocheirids.
