Document Summary
Section 1: natural history of exploitation, pages 11 15. Most herbivores are not true predators because they often do not kill the plants they eat. Example: during the summer, snowshoe hares typically nibble on the leafy parts of plants, which the plant can regrow. Grazers are herbivores that specialize on herbaceous plants (grasses, herbs, forbs) Browsers eat the leaves, bark, and twigs of woody plants. Some herbivores both graze and browse, depending on food availability. Example: during the winter months when grasses and herbs are not available, hares switch to eating woody shoots and bark of trees and shrubs. Herbivores that specialize on seeds are granivores, while those specializing on fruits are frugivores. Seeds and fruits are high-quality foods, but grazers and browsers face a dietary challenge. Leaves and woody parts of plants are primarily made of cellulose, which is indigestible to mammals.
