Abstract

Nine microsatellite loci are isolated and characterized for the marine isopod Limnoria sp., a model invertebrate species for the study of connectivity of marine brooders with high potential of dispersal through rafting. Analysis of 35 individuals of one population revealed a mean number of alleles of 12.66 and mean expected heterozygosity of 0.83, indicating a high level of variability at most loci. These polymorphic microsatellite loci should be useful to the study of the geographical distribution of the genetic diversity of this species of Limnoria. © 2007 The Authors.
