Alcelaphini
The subfamily Alcelaphinae or tribe Alcelaphini of the family Bovidae contains wildebeest, hartebeest, bonteboks, and several similar species. Depending on the classification, there are 6–10 species placed in four genera, although ''Beatragus'' is sometimes considered a subgenus of ''Damaliscus'', and ''Sigmoceros'' for the Lichtenstein's hartebeest.

Hartebeest
The hartebeest (; ''Alcelaphus buselaphus''), also known as kongoni or kaama, is an African antelope. It is the only member of the genus ''Alcelaphus''. Eight subspecies have been described, including two sometimes considered to be independent species. A large antelope, the hartebeest stands just over at the shoulder, and has a typical head-and-body length of . The weight ranges from . It has a particularly elongated forehead and oddly-shaped horns, a short neck, and pointed ears. Its legs, which often have black markings, are unusually long. The coat is generally short and shiny. Coat colour varies by the subspecies, from the sandy brown of the western hartebeest to the chocolate brown of the Swayne's hartebeest. Both sexes of all subspecies have horns, with those of females being more slender. Horns can reach lengths of . Apart from its long face, the large chest and the sharply sloping back differentiate the hartebeest from other antelopes. A conspicuous hump over the ...

Bovidae
The Bovidae comprise the biological family of cloven-hoofed, ruminant mammals that includes cattle, bison, buffalo, antelopes, and caprines. A member of this family is called a bovid. With 143 extant species and 300 known extinct species, the family Bovidae consists of 11 (or two) major subfamilies and thirteen major tribes. The family evolved 20 million years ago, in the early Miocene. The bovids show great variation in size and pelage colouration. Excepting some domesticated forms, all male bovids have two or more horns, and in many species, females possess horns, too. The size and shape of the horns vary greatly, but the basic structure is always one or more pairs of simple bony protrusions without branches, often having a spiral, twisted or fluted form, each covered in a permanent sheath of keratin. Most bovids bear 30 to 32 teeth. Most bovids are diurnal. Social activity and feeding usually peak during dawn and dusk. Bovids typically rest before dawn, during midday ...

Topi
''Damaliscus lunatus jimela'' is a subspecies of topi, and is usually just called a topi. It is a highly social and fast type of antelope found in the savannas, semi-deserts, and floodplains of sub-Saharan Africa. Names The word ''tope'' or ''topi'' is Swahili, and was first recorded in the 1880s by the German explorer Gustav Fischer to refer to the local topi population in the Lamu island region of Kenya; this population is now designated as ''Damaliscus lunatus topi''. Contemporaneously, in English, sportsmen referred to the animal as a Senegal hartebeest, as it was considered the same species as what is now recognised as ''D. lunatus korrigum''. Other names recorded in East Africa by various German explorers were in Kisukuma and in Kinyamwezi. The Luganda name was according to Neumann, or according to Lugard. By the turn of the 19th century this antelope was called a topi by most in English. Writing in 1908, Richard Lydekker complains that it would have so much ...

Megalotragus
''Megalotragus'' was a genus of very large extinct African alcelaphines that occurred from the Pliocene to early Holocene.Thackeray, John Francis. (2015). Faunal Remains from Holocene Deposits, Excavation 1, Wonderwerk Cave, South Africa. African Archaeological Review. Its skull resembled that of modern hartebeests, but it differed in having a larger body size and wildebeest-like proportions. ''Megalotragus'' includes some of the largest bovid species in the tribe Alcelaphini, reaching a shoulder height of . The genus consists of three species of which ''Megalotragus priscus'' survived until the early Holocene 7.500 C14yBP. Description With a distance between the tips of its horns of around , ''Megalotragus'' is probably the largest alcelaphine bovid ever recorded, much bigger than the extanct wildebeest. The skull of ''Megalotragus'' is similar to that of the hartebeest: characterized by extreme elongation, and the fusion and posterior placement of the horn pedicels. However, ...

Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia.

Tribe (biology)
In biology, a tribe is a taxonomic rank above genus, but below family and subfamily. It is sometimes subdivided into subtribes. By convention, all taxonomic ranks from genus upwards are capitalized, including both tribe and subtribe. In zoology, the standard ending for the name of a zoological tribe is "-ini". Examples include the tribes Caprini (goat-antelopes), Hominini (hominins), Bombini (bumblebees), and Thunnini (tunas). The tribe Hominini is divided into subtribes by some scientists; subtribe Hominina then comprises "humans". The standard ending for the name of a zoological subtribe is "-ina". In botany, the standard ending for the name of a botanical tribe is "-eae". Examples include the tribes Acalypheae and Hyacintheae. The tribe Hyacintheae is divided into subtribes, including the subtribe Massoniinae. The standard ending for the name of a botanical subtribe is "-inae". In bacteriology, the form of tribe names is as in botany, e.g., Pseudomonadeae, based on the ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Korrigum
The korrigum (''Damaliscus lunatus korrigum''), also known as Senegal hartebeest, is a subspecies of the Damaliscus lunatus, topi, a large African antelope. Taxonomy An 1822–1824 British expedition across the Sahara to the ancient kingdom of Kanem–Bornu Empire#Successors, Bornu, returned with single set of horns of an antelope known in the language of that land as a ''korrigum''. These horns were classified as a new species by William Ogilby in an article in the journal ''Proceedings of the Zoological Society of London'' dated 1836, but published in 1837. Description Korrigan were said to differ from the tiang subspecies based on the tail tuft being more bushy, and the pelage being more reddish. In the tiang, the patches of dark hair on the legs were said to be somewhat larger. In the Belgian Congo, a topi was shot in the 19th century which is intermediate between these two. Morphometrically, korrigan and tiang were found to be indistinguishable. Range and conservation Ko ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hirola
The hirola (''Beatragus hunteri''), also called the Hunter's hartebeest or Hunter's antelope, is a critically endangered antelope species found on the border between Kenya and Somalia. It was first described by the big game hunter and zoologist H.C.V. Hunter in 1888. It is the only living member of the genus ''Beatragus'', though other species are known from the fossil record. The global hirola population is estimated at 300–500 animals and there are none in captivity.Probert, J. (2011The Tsavo hirola: current status and future management MSc thesis.

Lichtenstein's Hartebeest
Lichtenstein's hartebeest (''Alcelaphus buselaphus lichtensteinii'')Wilson, Don E. & Reeder, DeeAnn M. (editors). 2005. Mammal Species of the World. A Taxonomic and Geographic Reference (3rd ed), Johns Hopkins University Press, 2,142 ppAvailable online/ref> is a subspecies of the hartebeest antelope that dwells in savannahs and floodplains of Southeastern-Central Africa. It is sometimes classified as a unique species, ''Sigmoceros lichtensteinii''. It derives its name from zoologist Martin Lichtenstein. Description It typically stands about at the shoulder and have a mass of around . It has a red-brown colour, which is lighter on the underbelly. The horns found on both sexes appear from the side to be shaped like the letter 'S', and appear from the front to be shaped like the letter 'O' with its upper portions missing. The horns are slightly ridged and reach over in length. Behavior They live on areas where they eat grasses. They are diurnal (active in the day). They gather i ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
