Abstract

We describe primers and amplification conditions for seven microsatellite loci that were developed and characterized in the commercially harvested surfclam Mactromeris polynyma. Five of these loci were polymorphic: we found 6 to 23 alleles per locus among 100 individuals from one population in Nova Scotia, with some large heterozygote deficits that may reflect unrecognized temporal genetic variation. We are using these markers to investigate temporal and spatial genetic structure in this species.
