Abstract
We examined diets of bison (Bos bison) bulls, cows, juveniles, and calves t o determine differences in quality of diets between groups. Our results sho wed that bulls had a significantly higher proportion of C-4 grasses in thei r diet than cows, juveniles, or calves. Diets or calves were of higher qual ity than diets of bulls, cows, or juveniles. Our results provide support Fo r the sexual dimorphism-body size hypothesis of sexual segregation in large ungulates.
