Gender Discrimination of Tigers by Using Their Pugmarks

Abstract

We evaluated gender discrimination of tigers (Panthera tigris) using the shape of their pugmarks. Discriminant Function Analysis (DFA) and logistic regression were used to discriminate gender of 13 known tigers from nine easy-to-obtain pugmark measurements. Both multivariate techniques were quite accurate in discriminating genders; the most accurate and parsimonious model was DFA with parameters of pugmark length and width. Our technique can be used to acquire sex-ratio data of tiger populations in areas where pugmarks are easy to obtain.
