Mean per cent volumes of animal matter in diets of these rodents over the entire study were: D. ordii, 4.4 per cent; 0. leucogaster, 73.9 per cent; P. maniculatus, 39.0 per cent; and S. tridecemlineatus, 44.0 per cent. The greatest amount of seasonal variation in per cent volume animal matter in the diet was in P. maniculatus. Animal matter in diets of all four species was composed almost entirely of arthropods and a few parts of vertebrates. The most common arthropods [...]
