Keystone Resource

In conservation biology, a resource that is of vital importance to the preservation of an ecosystem. For example, elevation gradients in the tropics are viewed as a keystone resource because they allow frugivorous primates to move in elevations where there are different species of tree that provide nutritional diversity as well as different fruiting seasons. Los of keystone resources can mean los of animal diversity (for example, cutting down trees in the tropics leaves primate species without a habitat).
