HerbivoreLast Updated on 2014-02-13 16:58:29A herbivore is an animal that obtains its energy and nutrients by feeding on plants. Different types of herbivores eat different plant parts. For example, folivores feed on leaves, frugivores feed on fruits, granivores feed on seeds, pollinivores feed on pollen, and nectarivores feed on nectar. Herbivores can vary greatly in size, ranging from the largest terrestrial animals (elephants) and large marine mammals such as manatees and dugongs to small insects, nematodes and thrips. Herbivores are primary consumers (they receive their energy by consuming primary producers), so they play an important trophic role in ecological communities and food webs.
Because mature leaves are low in nutrients, and difficult to digest because of their high cellulose content, animals use many different strategies to eat leaves. Animals that feed on grass leaves are generally... More »
Leather OakLast Updated on 2014-01-18 12:16:02
The Leather Oak, a California endemic, occurs primarily in the California interior chaparral and woodlands ecoregion. It is a species with strong affinity for ultramafic soils, a geochemical class of high magnesium, low calcium and nutrient deficient media. In appearance this is a shrub-like tree whose leathery leaves reveal its common name and obvious membership in the sclerophyll vegetation category, a morphological class of hard leaved species that may occur in such diverse places as Australia, Southern Africa, the Chilean matorral and the Mediterranean Basin as well as the California Floristic Province.
Q durata has two recognized varieties:
