Comparison of Techniques for Sex Determination of American Martens

Accurate determination of sex in harvested species is critical for understanding demography and developing population models for management. We used genetic-based sex identification to assess accuracy of external carcass and pelt examination at registration and maximum canine root area (MRA) to dete...

Zusammenfassung:	Accurate determination of sex in harvested species is critical for understanding demography and developing population models for management. We used genetic-based sex identification to assess accuracy of external carcass and pelt examination at registration and maximum canine root area (MRA) to determine sex of American martens (Martes americana) trapped in the Upper Peninsula of Michigan, 2000–2004. Overall percent similarity between MRA and genetic-based sex determination was 98.4% (n = 188). In contrast, only 84.6% (n = 421) of martens were similarly classified using external examination. For external examination, percent similarity to genetic-based sex determination for juveniles (
