Abstract

We used primers developed for the SRY gene in otters (Lutra lutra) to determine sex in pine marten (Martes martes). The otter SRY primers worked accurately for pine marten and assigned sex correctly in most replicates. These primers can be used on tissue and noninvasively collected hair samples for the identification of the animal's sex. We found that, based on five sets of replicates, DNA extracted from leg muscle and hair gave significantly better results than DNA extracted from ear tissue. Finally, results indicate the optimum number of PCR replicates to accurately assign sex using this technique.
