摘要：

We describe the development of 13 variable microsatellites developed to investigate population structure and dispersal in the sea urchin Centrostephanus rodgersii. This species is the dominant grazing herbivore in southeast Australian coastal waters and has the ability to modify benthic community structure. The microsatellites we identified showed a range of allele numbers (4-21) and expected heterozygosity (0.32-0.91) in two sampled populations. Contrary to previous findings in free-spawning marine invertebrates, genotype proportions in neither population deviated significantly from Hardy-Weinberg expectations.
