The grazing optimization hypothesis was developed in one of these ecosystems, whose animals include pronghorn and wildebeest.
In one of these ecosystems, David Tilman found a positive correlation between alpha diversity and community stability. These terrestrial ecosystems expanded during the Miocene epoch. From studies of one of these ecosystems, McNaughton formulated a form of the intermediate disturbance hypothesis stating that herbivory can lead to increased primary productivity. Forbs are common organisms in these ecosystems, which are often characterized by mollisols with agriculturally-valuable A-horizons. The grazing optimization hypothesis was developed in one of these ecosystems, whose animals include pronghorn and wildebeest. For 10 points, name these ecosystems exemplified by the Great Plains and Serengeti, characterized by few trees and a whole lot of grass.
