A pronghorn is picky — and has to be. Small bodies need less food, but they also need better food: more protein, fewer carbohydrates, less lignin. The pronghorns' perspective on forbs makes their relationship to a grassland very different from the bison's. For the bison, it's just grass going on forever, but for the pronghorn there are patches of forbs growing among the grasses. Pronghorn territoriality on the National Bison Range seems to have died a demographic death in 1978–79. But in most species in most situations, the abundance and distribution of food are crucial determinants of territoriality.
