- Abstract
The limpet Patella ferruginea is one of the most endangered marine invertebrates on western Mediterranean rocky shores. We have isolated and characterised 11 polymorphic microsatellites markers to provide new tools to investigate genetic structure and gather information necessary for the proper management of this severely threatened species. The number of alleles per locus ranged from 2 to 16 (mean; Na = 8.37) with an average observed heterozygosity of 0.64 (He = 0.66). The levels of polymorphism uncovered at these loci suggest that they should be useful for population genetic studies, parentage analysis and assessment of connectivity among protected areas. None of the pairwaise comparisons among loci showed significant linkage disequilibrium after sequential Bonferroni correction. All but one locus (Pf-31IF1) conformed to HW equilibrium. Further investigation revealed that departures at Pf-31IF1 were not caused by null alleles. Results from cross-species amplifications suggest that some of these loci may also be useful for Patella tenuis (two loci) P. ulyssiponensis (one locus) and P. piperata (three loci).
