Equidae is the taxonomic family of horses and related animals, including the extant horses, asses, and zebras, and many other species known only from fossils. The family evolved around 50 million years ago from a small, multi-toed ungulate into larger, single-toed animals. All extant species are in the genus Equus, which originated in North America. Equidae belongs to the order Perissodactyla, which includes the extant tapirs and rhinoceros, and several extinct families.
Perissodactyla is an order of ungulates. The order includes about 17 living species divided into three families: Equidae, Rhinocerotidae (rhinoceroses), and Tapiridae (tapirs). They typically have reduced the weight-bearing toes to three or one of the five original toes, though tapirs retain four toes on their front feet. The nonweight-bearing toes are either present, absent, vestigial, or positioned posteriorly. By contrast, artiodactyls bear most of their weight equally on four or two of the five toes: their third and fourth toes. Another difference between the two is that odd-toed ungulates digest plant cellulose in their intestines, rather than in one or more stomach chambers as even-toed ungulates, with the exception of Suina, do.
The quagga is an extinct subspecies of the plains zebra that was endemic to South Africa until it was hunted to extinction in the late 19th century. It was long thought to be a distinct species, but early genetic studies have supported it being a subspecies of plains zebra. A more recent study suggested that it was the southernmost cline or ecotype of the species.
Zebras are African equines with distinctive black-and-white striped coats. There are three living species: the Grévy's zebra, plains zebra, and the mountain zebra. Zebras share the genus Equus with horses and asses, the three groups being the only living members of the family Equidae. Zebra stripes come in different patterns, unique to each individual. Several theories have been proposed for the function of these stripes, with most evidence supporting them as a deterrent for biting flies. Zebras inhabit eastern and southern Africa and can be found in a variety of habitats such as savannahs, grasslands, woodlands, shrublands, and mountainous areas.
The plains zebra, also known as the common zebra, is the most common and geographically widespread species of zebra. Its range is fragmented, but spans much of southern and eastern Africa south of the Sahara. Six or seven subspecies have been recognised, including the extinct quagga which was thought to be a separate species. More recent research supports variations in zebra populations being clines rather than subspecies.
The mountain zebra is a zebra species in the family Equidae, native to southwestern Africa. There are two subspecies, the Cape mountain zebra found in South Africa and Hartmann's mountain zebra found in south-western Angola and Namibia.
Equus is a genus of mammals in the family Equidae, which includes horses, asses, and zebras. Within the Equidae, Equus is the only recognized extant genus, comprising seven living species. Like Equidae more broadly, Equus has numerous extinct species known only from fossils. The genus most likely originated in North America and spread quickly to the Old World. Equines are odd-toed ungulates with slender legs, long heads, relatively long necks, manes, and long tails. All species are herbivorous, and mostly grazers, with simpler digestive systems than ruminants but able to subsist on lower-quality vegetation.
Burchell's zebra is a southern subspecies of the plains zebra. It is named after the British explorer and naturalist William John Burchell. Common names include bontequagga, Damaraland zebra, and Zululand zebra. Burchell's zebra is the only subspecies of zebra which may be legally farmed for human consumption.
Kidepo Valley National Park is a 1,442 square kilometres (557 sq mi) national park in the Karamoja region in northeast Uganda. Kidepo is rugged savannah, dominated by the 2,750 metres (9,020 ft) Mount Morungole and transected by the Kidepo and Narus rivers.
Axel Johann Einar Lönnberg was a Swedish zoologist and conservationist. Lönnberg was born in Stockholm. He was head of the Vertebrate Department of the Naturhistoriska Riksmuseet from 1904 to 1933.
Grant's zebra is the smallest of the seven subspecies of the plains zebra. This subspecies represents the zebra form of the Serengeti-Mara ecosystem and others across central Africa.
The Quagga Project is an attempt by a group in South Africa to use selective breeding to achieve a breeding lineage of Burchell's zebra which visually resemble the extinct quagga.
Reinhold Eugen Rau was a German natural historian who initiated the Quagga Project in South Africa, which aims to re-breed the extinct quagga, a sub-species of zebra.
The Cape mountain zebra is a subspecies of mountain zebra that occurs in certain mountainous regions of the Western and Eastern Cape provinces of South Africa.
Crawshay's zebra is a subspecies of the plains zebra native to eastern Zambia, east of the Luangwa River, Malawi, southeastern Tanzania, and northern Mozambique south to the Gorongoza District. Crawshay's zebras can be distinguished from other subspecies of plains zebras in that its lower incisors lack an infundibulum. Crawshay's zebra has very narrow stripes compared to other forms of the plains zebra.
Felis margarita margarita, sometimes called the Saharan sand cat, is a subspecies of the sand cat native to the Sahara.
Chapman's zebra, named after explorer James Chapman, is a subspecies of the plains zebra from southern Africa.
Boma National Park is a protected area in eastern South Sudan near the Ethiopian border. It was established in 1977 and covers 22,800 km2 (8,800 sq mi) of grasslands and floodplains.
The Narus River flows in a northwesterly direction through the southern portion of Kidepo Valley National Park in northern Uganda, joining the larger Kidepo River near Komoloich, about 13 kilometres (8.1 mi) after entering Eastern Equatoria state of South Sudan. The name Narus is derived from the Karamajong word for mud.
The East African cheetah, is a cheetah population in East Africa. It lives in grasslands and savannas of Tanzania, Kenya, Uganda and Somalia. The cheetah inhabits mainly the Serengeti ecosystem, including Maasai Mara, and the Tsavo landscape.
