query: What eats an antelope?
passage: Addax
The addax mainly eats grasses and leaves of any available shrubs, leguminous herbs and bushes. These animals are well-adapted to exist in their desert habitat, as they can live without water for long periods of time. Addax form herds of five to 20 members, consisting of both males and females. They are led by the oldest female. Due to its slow movements, the antelope is an easy target for its predators: lions, humans, African wild dogs, cheetahs, and leopards. Breeding season is at its peak during winter and early spring. The natural habitat of the addax are arid regions, semideserts and sandy and stony deserts.
passage: Antelope Island bison herd
If there were significant apex predators for the herd on Antelope Island, then yearly culling of the herd would not be necessary. However, there are no significant predators. Bison are large herd animals that defend their young vigorously. Other mammals found on the island include coyotes, bobcats, mule deer (estimated to number 250), pronghorn antelope (approximately 200 on the island), and bighorn sheep (estimated 200). The coyotes and bobcats are far too small to establish significant predation on bison, even bison calves, and the other large mammals such as mule deer, pronghorn antelope and big horn sheep are too small to successfully compete enough to displace the bison herds or otherwise restrict bison range and feeding. Bald eagles, Golden eagles and various large hawks and falcons are also found on Antelope Island, but likewise are incapable of preying on large animals such as bison. Only wolves or bears would be likely to function successfully as apex predators of bison, but Antelope Island is considered to be unsuitable to them. Besides being very close to a major population center, the Wasatch Front including Salt Lake City, Antelope Island at 42 square miles (26,000 acres) could perhaps support a small population of these predators, but would not be likely to support a large enough population of predators to maintain genetic diversity and viability.
