Ten new polymorphic microsatellite loci for North American river otters (Lontra canadensis) and their utility in related mustelids

摘要

We describe 10 novel North American river otter (Lontra canadensis) polymorphic microsatellite loci. Individuals from two river drainages in New York were sampled, and the number of alleles per locus ranged from two to 12 (Drainage 1) and two to 10 (Drainage 2). Observed heterozygosities ranged from 0.21 to 0.83 (Drainage 1) and 0.20 to 0.80 (Drainage 2). Preliminary screening revealed that loci amplified in five other mustelids [Mantes pennanti (n = 6), Martes fiona (n = 8), Mustela frenata (n = 8), Mustela erminea (n = 8) and Mustela vison (n = 5)].
