Rodent Population Densities and Food Habits in Arizona Ponderosa Pine Forests

摘要

Habitat preference, effect of timber harvesting on population densities, and food habits were determined for small rodents inhabiting ponderosa pine in north-central Arizona. Forbs were the primary summer food item for all rodent species. Seeds and flowers comprised 75% of the vegetative diet and leaves or stems 25%. Approximately 85% of the total diet was vegetation, and 15% was insects.
