Quagga
The quagga ( or ) (''Equus quagga 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 mtDNA 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. The quagga is believed to have been around long and tall at the shoulders. It was distinguished from other zebras by its limited pattern of primarily brown and white stripes, mainly on the front part of the body. The rear was brown and without stripes, and appeared more horse-like. The distribution of stripes varied considerably between individuals. Little is known about the quagga's behaviour, but it may have gathered into herds of 30–50. Quaggas were said to be wild and lively, yet were also considered more docile than the related Burchell's zebra. They were once found in great num ...

Plains Zebra
The plains zebra (''Equus quagga'', formerly ''Equus burchellii'') 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 quagga which was thought to be a separate species. More recent research supports variations in zebra populations being Cline (biology), clines rather than subspecies. Plains zebras are intermediate in size between the larger Grévy's zebra and the smaller mountain zebra and tend to have broader stripes than both. Great variation in coat patterns exists between clines and individuals. The plains zebra's habitat is generally, but not exclusively, treeless grasslands and savanna woodlands, both tropical and temperate. They generally avoid desert, dense rainforest and permanent wetlands. Zebras are preyed upon by lions and spotted hyenas, Nile crocodiles and, to a lesser extent, African leopard, leopards ...

Quagga Project
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 (''Equus quagga burchellii'') which visually resemble the extinct quagga (''Equus quagga quagga''). History In 1955, Lutz Heck suggested in his book ' that careful selective breeding with the plains zebra could produce an animal resembling the extinct quagga: a zebra with reduced striping and a brownish basic colour. In 1971, Reinhold Rau visited various museums in Europe to examine the quagga specimens in their collections and decided to attempt to re-breed the quagga. Rau later contacted several zoologists and park authorities, but they were on the whole negative because the quagga has left no living descendants, and thus the genetic composition of this animal is not present in living zebras. Rau did not abandon his re-breeding proposal, as he considered the quagga to be a subspecies of the plains zebra. In 1984, molecular studies of mitoch ...

Hippotigris
Zebras (, ) (subgenus ''Hippotigris'') are African equines with distinctive black-and-white striped coats. There are three living species: Grévy's zebra (''Equus grevyi''), the plains zebra (''E. quagga''), and the mountain zebra (''E. 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 patterns, 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. Zebras are primarily grazers and can subsist on lower-quality vegetation. They are preyed on mainly by lions, and typically flee when threatened but also bite and kick. Zebra species differ in social behaviour, with plains and mountain zebr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Burchell's Zebra
Burchell's zebra (''Equus quagga burchellii'') 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 (Gray, 1824). Burchell's zebra is the only subspecies of zebra which may be legally farmed for human consumption. Physical characteristics Like most plains zebras, females and males are about the same size, standing at the shoulder. They weigh between . Year-round reproduction observed in this subspecies in Etosha National Park, Namibia, concludes synchronization of a time budget between males and females, possibly explaining the lack of sexual dimorphism. Burchell's zebras are described as being striped on the head, the neck, and the flanks, and sparsely down the upper segments of the limbs then fading to white. One or two shadow stripes rest between the bold, broad stripes on the haunch. This main distinguishing characteristic sets the ...

Karoo
The Karoo ( ; from the Afrikaans borrowing of the South Khoekhoe Khoemana (also known as !Orakobab or Korana) word is a semidesert natural region of South Africa. No exact definition of what constitutes the Karoo is available, so its extent is also not precisely defined. The Karoo is partly defined by its topography, Karoo Supergroup, geology and climate, and above all, its low rainfall, arid air, cloudless skies, and extremes of heat and cold. The Karoo also hosted a well-preserved ecosystem hundreds of millions of years ago which is now represented by many fossils. The Karoo formed an almost impenetrable barrier to the interior from Cape Town, and the early adventurers, explorers, hunters, and travelers on the way to the Highveld unanimously denounced it as a frightening place of great heat, great frosts, great floods, and great droughts. Today, it is still a place of great heat and frosts, and an annual rainfall of between 50 and 250 mm, though on some of the mountains i ...

London Zoo
London Zoo, previously known as ZSL London Zoo or London Zoological Gardens and sometimes called Regent's Park Zoo, is the world's oldest scientific zoo. It was opened in London on 27 April 1828 and was originally intended to be used as a collection for scientific study. In 1831 or 1832, the Tower of London menagerie animals were transferred to the zoo's collection. It was opened to the public in 1847. As of December 2022, it houses a collection of 14,926 individuals, making it one of the largest collections in the United Kingdom. It is managed under the aegis of the Zoological Society of London (established in 1826) and is situated at the northern edge of Regent's Park, on the boundary line between the City of Westminster and the borough of Camden (the Regent's Canal runs through it). The Society also has a more spacious site at Whipsnade Zoo in Bedfordshire where larger animals, such as elephants and rhinos, have been moved. As well as being the first scientific zoo, Lond ...

Onomatopoeic
Onomatopoeia (or rarely echoism) is a type of word, or the process of creating a word, that phonetically imitates, resembles, or suggests the sound that it describes. Common onomatopoeias in English include animal noises such as ''oink'', ''meow'', '' roar'', and ''chirp'', among other sounds such as '' beep'' or ''hiccup''. Onomatopoeia can differ by language: it conforms to some extent to the broader linguistic system. Hence, the sound of a clock may be expressed variously across languages: as ' in English, in Spanish and Italian (see photo), in Mandarin, in Japanese, or in Hindi, Urdu, and Bengali. Etymology and terminology The word ''onomatopoeia'', with rarer spelling variants like ''onomatopeia'' and ''onomatopœia'', is an English word from the Ancient Greek compound ὀνοματοποιία, ''onomatopoiía'', meaning 'name-making', composed of ὄνομα, ''ónoma'', meaning "name"; and ποιέω, ''poiéō'', meaning "making". It is pronounced . Word ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Khoikhoi
Khoikhoi (Help:IPA/English, /ˈkɔɪkɔɪ/ Help:Pronunciation respelling key, ''KOY-koy'') (or Khoekhoe in Namibian orthography) are the traditionally Nomad, nomadic pastoralist Indigenous peoples, indigenous population of South Africa. They are often grouped with the hunter-gatherer San people, San (literally "foragers") peoples, the accepted term for the two people being Khoisan. The designation "Khoikhoi" is actually a ''kare'' or praise address, not an ethnic endonym, but it has been used in the literature as an ethnic term for Khoe–Kwadi languages, Khoe-speaking peoples of Southern Africa, particularly pastoralist groups, such as the Inqua people, Inqua, Griqua people, Griqua, Gonaqua, Nama people, Nama, Attequa. The Khoekhoe were once known as ''Hottentot (racial term), Hottentots'', a term now considered offensive."Hottentot, n. and adj."

Tshwa
Tsoa, Tshwa or Tshuwau, also known as Kua and Hiechware, is an East Kalahari Khoe dialect cluster spoken by several thousand people in Botswana and Zimbabwe. One of the dialects is Tjwao (formerly spelled 'Tshwao'), the only Khoisan language in Zimbabwe, where "Koisan" is a language officially recognised in the constitution. Dialects Tsoa–Kua is a dialect cluster, which is still poorly studied but seems to include: *Tsoa, also known as Hiechware and as various other combinations of Hio-, Hie-, Hai- + Chwa, Tshwa, Chuwau, Tshuwau + -re, -ri; also as Sarwa, Sesarwa (the Tswana name), Gǁabakʼe-Ntshori, Tati, and Kwe-Etshori Kwee. Zimbabwean Tjwao apparently belongs here. *Kua, also spelled Cua and Tyhua. That is, both Tsoa and Kua may be pronounced something like , and it's not clear that they are distinct dialects. *Cire Cire , spoken in the area around Nata in Botswana.

Calabrian (stage)
Calabrian is a subdivision of the Pleistocene Epoch of the geologic time scale, defined as 1.8 Ma—774,000 years ago ± 5,000 years, a period of ~. The end of the stage is defined by the last magnetic pole reversal (781 ± 5 Ka) and plunge into an ice age and global drying possibly colder and drier than the late Miocene (Messinian) through early Pliocene (Zanclean) cold period. Originally the Calabrian was a European faunal stage primarily based on mollusk fossils. It has become the second geologic age in the Early Pleistocene. History of the definition of the Calabrian Because sea shells are much more abundant as fossils, 19th- and early-20th-century geo-scientists used the plentiful and well-differentiable Mollusca (mollusks) and Brachiopods to identify stratigraphic boundaries. Thus the Calabrian was originally defined as an assemblage of mollusk fossils, most brachiopods being extinct by then. Efforts were then made to find the best representation of that assemblage in ...
