The Ecology of the Earth's Grazing Ecosystems
Douglas A. Frank, Samuel J. Tracy McNaughton & F. Benjamin - Bioscience v. 48 no 7, July 1998.
Excerpt:
"As recently as 150 years ago, most of Earth's grasslands supported large migratory populations of hoofed herbivores belonging to the Artiodactyla, Perissodactyla, and Proboscidea -- that is, ungulates. These herbivores included bison (Bison bison) on the North American plains, saiga antelope (Saiga Tatarica) on the Eurasian steppe, wildebeest (Connochaetes taurinus) and zebra (Equus burchelli) on the African savanna, and the ecologically equivalent kangaroos (Macropodidae) on the Australian savanna...."
