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 ...

Bubal Hartebeest
The bubal hartebeest, also known as northern hartebeest or bubal antelope or simply bubal (''Alcelaphus buselaphus buselaphus'') is the extinct nominal (i.e., first described) subspecies of hartebeest. It was formerly found north of the Saharan Desert. Other subspecies live currently in grasslands south of the Sahara, from Senegal in the west to Eritrea and Ethiopia in the east and down to central Tanzania. The red hartebeest and Lichtenstein's hartebeest, alternatively considered subspecies or sister species of the common hartebeest, are present in southern Africa. Name The ancient name for the bubal hartebeest was ''bubalus'' (Latin) or ''boubalos'' (Ancient Greek language, Greek), from which the term :wikt:buffalo, buffalo is derived. Authors that describe the wild ''bubali'' of north Africa include Herodotus, Dio Cassius, Strabo, Polybius, Diodorus Siculus and Oppian. Description The bubal hartebeest was described as uniformly sand colored, save for "an ill-defined patch o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coke's Hartebeest
Coke's hartebeest (''Alcelaphus buselaphus cokii'') or ''Kongoni'' is a large migratory antelope that is native to Kenya and Tanzania. It can breed with Lelwel hartebeest to produce a hybrid known as the Kenya Highland hartebeest (''Alcelaphus buselaphus lelwel'' x ''cokii''). Appearance The Coke's hartebeest has a long and narrow face with pointed ears. It has long legs, a sloping back, and ridged horns that are found in both males and females. It has short reddish-brown fur, a white rump, and a short tail with a blackish tuft at the end. Calves have a paler appearance. Male Kongonis may measure anywhere from 117–124 cm (46-48 inches) and weigh about 129–171 kg (284-376 lbs), while female Kongonis are slightly smaller with a height of 112 cm (44 inches) and weigh around 116–148 kg (255-326 lbs). The horns may be up to 70 cm long. Behavior Herding Behavior The Coke's hartebeest herds represent mostly female hierarchies with a typic ...

Swayne's Hartebeest
Swayne's hartebeest (''Alcelaphus buselaphus swaynei'') is an endangered antelope native to Ethiopia. Two of the largest remaining populations are located in Senkelle Swayne's Hartebeest Sanctuary, Nechisar National Park and Maze National Park. It has been extirpated from Somalia. It is named after British officer H. G. C. Swayne (1860–1940). When it comes to their population status, during the times before the early 1890s the Swayne's hartebeest was very common throughout Ethiopia and Somalia. The population then declined due to an epidemic that happened during the mid-1890s which brought about an extremely high mortality rate for wildlife and livestock which as a result were labeled as “in danger of extermination”. Swayne's hartebeest exhibits ecological differences from other subspecies of hartebeests in that they prefer grassland habitats during wet and dry seasons. It likes to select short grass areas of no more than 30 centimeters for feeding, and has a preference ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Hartebeest
The western hartebeest (''Alcelaphus buselaphus major'') is an antelope native to the medium to tall grassland plains of Benin, Burkina Faso, Cameroon, the Central African Republic, Chad, Côte d'Ivoire, Ghana, Guinea, Guinea-Bissau, Mali, Niger, Nigeria, Senegal, and Togo. It is possibly extirpated from Gambia. Average adults stand tall at the shoulder and weigh . A western hartebeest's coat is fawn-colored, ranging from tan to dark brown. It has a small hump at the front shoulders. It has slim legs and a very narrow face. Both sexes are horned. Horns may be long. Considerable variation in horn growth occurs, but they generally grow sideways out from the head, before curving forward, then inward and backward. The horns are terminated by sharp tips. The western hartebeest is mainly active during the day. A herbivore, it grazes during the cooler morning and afternoon periods, resting in shaded areas during the hot daytime. Females form herds of five to 12 members, while ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tora Hartebeest
{{eventoedungulate-stub ...
The tora hartebeest, or simply tora (''Alcelaphus buselaphus tora''), is an extremely endangered antelope, native to Eritrea and Ethiopia. It has possibly been extirpated from Sudan. One of the most critically endangered large mammals in the world, it is threatened by poaching and habitat loss. Perhaps fewer than 250 individuals remain in the wild and there is no captive population, as little to no action has been taken to preserve them.

Fauna Of Africa
The fauna of Africa, in its broader sense, is all the animals living in Africa and its surrounding seas and islands. The more characteristic African fauna is found in the Afrotropical realm. Lying almost entirely within the tropics, and equally to north and south of the equator creates favourable conditions for rich wildlife. Africa is home to many of the world's most famous fauna in human culture such as lions‚ rhinos‚ cheetahs‚ giraffes‚ antelope, hippos, leopards, zebras‚ and African elephants among many others. Origins and history of African fauna Whereas the earliest traces of life in fossil record of Africa date back to the earliest times, the formation of African fauna as we know it today, began with the splitting up of the Gondwana supercontinent in the mid-Mesozoic era. After that, four to six faunal assemblages, the so-called African Faunal Strata (AFSs) can be distinguished. The isolation of Africa was broken intermittently by discontinuous "filter routes" tha ...

Albert Günther
Albert Karl Ludwig Gotthilf Günther FRS, also Albert Charles Lewis Gotthilf Günther (3 October 1830 – 1 February 1914), was a German-born British zoologist, ichthyologist, and herpetologist. Günther is ranked the second-most productive reptile taxonomist (after George Albert Boulenger) with more than 340 reptile species described. Early life and career Günther was born in Esslingen in Swabia (Württemberg). His father was a ''Stiftungs-Commissar'' in Esslingen and his mother was Eleonora Nagel. He initially schooled at the Stuttgart Gymnasium. His family wished him to train for the ministry of the Lutheran Church for which he moved to the University of Tübingen. A brother shifted from theology to medicine, and he, too, turned to science and medicine at Tübingen in 1852. His first work was "''Ueber den Puppenzustand eines Distoma''". He graduated in medicine with an M.D. from Tübingen in 1858, the same year in which he published a handbook of zoology for students of ...

Process (anatomy)
In anatomy, a process ( la, processus) is a projection or outgrowth of tissue from a larger body. For instance, in a vertebra, a process may serve for muscle attachment and leverage (as in the case of the transverse and spinous processes), or to fit (forming a synovial joint), with another vertebra (as in the case of the articular processes).Moore, Keith L. et al. (2010) ''Clinically Oriented Anatomy'', 6th Ed, p.442 fig. 4.2 The word is used even at the microanatomic level, where cells can have processes such as cilia or pedicels. Depending on the tissue, processes may also be called by other terms, such as ''apophysis'', ''tubercle'', or ''protuberance''. Examples Examples of processes include: *The many processes of the human skull: ** The mastoid and styloid processes of the temporal bone ** The zygomatic process of the temporal bone ** The zygomatic process of the frontal bone ** The orbital, temporal, lateral, frontal, and maxillary processes of the zygomatic bone ...

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinction
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tanzania
Tanzania (; ), officially the United Republic of Tanzania ( sw, Jamhuri ya Muungano wa Tanzania), is a country in East Africa within the African Great Lakes region. It borders Uganda to the north; Kenya to the northeast; Comoro Islands and the Indian Ocean to the east; Mozambique and Malawi to the south; Zambia to the southwest; and Rwanda, Burundi, and the Democratic Republic of the Congo to the west. Mount Kilimanjaro, Africa's highest mountain, is in northeastern Tanzania. According to the United Nations, Tanzania has a population of million, making it the most populous country located entirely south of the equator. Many important hominid fossils have been found in Tanzania, such as 6-million-year-old Pliocene hominid fossils. The genus Australopithecus ranged across Africa between 4 and 2 million years ago, and the oldest remains of the genus ''Homo'' are found near Lake Olduvai. Following the rise of '' Homo erectus'' 1.8 million years ago, humanity spread ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Destruction
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...
