متن کاملCross-species characterisation of polymorphic microsatellite loci in the giant otter (Pteronura brasiliensis).
Nineteen microsatellite loci developed for the Eurasian otter (Lutra lutra) and 15 loci developed for the North American river otter (Lontra canadensis) were tested for ease of amplification and degree of polymorphism on a set of 20 giant otter (Pteronura brasiliensis) faecal samples from the Bolivian Amazon basin. Nineteen loci amplified consistently well, with polymorphisms ranging from two t...
