  1. Models tested whether diet varies as a function of sex and range between mating season and a multi-year time period. To test hypotheses 3 and 4, we subset the data for each range (CR, Central Range; NR, Northern Range), and analyzed the effect of sex on proxy measures for diet within each range. Columns labeled “x” and “y” denote the independent and dependent variables, respectively, for each model
