Abstract: | We used linear discriminant analysis to test the ability of commonly collected antler characteristics to discriminate ages in an isolated elk population. A discriminant model was developed using three sets of prior classification probabilities; (1) equal among all age-classes, (2) proportional to the sample used to construct the model and (3) mimicking hunter selection bias in Michigan. Antler characteristics were an imprecise predictor of age in harvested bull elk regardless of prior classification probabilities, with overall successful classification rates of 53-67%. Despite popular beliefs, antler characteristics are poor indicators of bull elk ages, even in a small, geographically isolated population such as Michigan's. |
