Oryx
''Oryx'' is a genus consisting of four large antelope species called oryxes. Their pelage is pale with contrasting dark markings in the face and on the legs, and their long horns are almost straight. The exception is the scimitar oryx, which lacks dark markings on the legs, only has faint dark markings on the head, has an ochre neck, and has horns that are clearly decurved. The Arabian oryx was only saved from extinction through a captive-breeding program and reintroduction to the wild. The scimitar oryx, which is now listed as extinct in the wild, also relies on a captive-breeding program for its survival.Database entry includes justification for why this species is listed as extinct in the wild. Etymology The term "oryx" comes from the Greek word ὄρυξ, ''óryx'', for a type of antelope. The Greek plural form is ''óryges'', although "oryxes" has been established in English. Herodotus mentions a type of gazelle in Libya called ὄρυς, ''orus'', probably related to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scimitar Oryx
The scimitar oryx (''Oryx dammah''), also known as the scimitar-horned oryx and the Sahara oryx, is a ''Oryx'' species that was once widespread across North Africa. In 2000, it was declared extinct in the wild on the IUCN Red List. A captive bred group was released into an acclimation enclosure within the Ouadi Rimé-Ouadi Achim Faunal Reserve in 2016, then reintroduced into the wild. An additional 21 individuals were released into the acclimation enclosure in 2017. The first ones to be relocated were released into the wild in 2016 and have adapted well to their surroundings. In 2017, another herd of 75 scimitar-horned oryxes arrived in an operation led by Chad's Ministry of Environment and Fisheries and the Sahara Conservation Fund. In 2021, 60 new calves were born, bringing the number in the wild to about 400. This particular oryx can survive for months or even years without drinking water. A grazing animal, it derives most of its daily moisture intake from plants. The scimit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arabian Oryx
The Arabian oryx (''Oryx leucoryx'') or white oryx is a medium-sized antelope with a distinct shoulder bump, long, straight horns, and a tufted tail. It is a bovid, and the smallest member of the genus ''Oryx'', native to desert and steppe areas of the Arabian Peninsula. The Arabian oryx was extinct in the wild by the early 1970s, but was saved in zoos and private reserves, and was reintroduced into the wild starting in 1980. In 1986, the Arabian oryx was classified as endangered on the IUCN Red List, and in 2011, it was the first animal to revert to vulnerable status after previously being listed as extinct in the wild. It is listed in CITES Appendix I. In 2016, populations were estimated at 1,220 individuals in the wild, including 850 mature individuals, and 6,000–7,000 in captivity worldwide. Etymology The taxonomic name ''Oryx leucoryx'' is from the Greek ' (gazelle or antelope) and ' (white). The Arabian oryx is also called the white oryx in English, ' in Hebrew, and is ...

Oryx Gazella
The gemsbok or South African oryx (''Oryx gazella'') is a large antelope in the genus ''Oryx''. It is native to the extremely dry, arid regions of Southern Africa; notably, the Kalahari Desert. Some authorities formerly classified the East African oryx, or ''beisa'' oryx, as a subspecies. The gemsbok is depicted on the coat of arms of Namibia, where the current population of the species is estimated at 373,000 individuals. In the town of Oranjemund, resident gemsbok wander freely around the streets, taking advantage of the vegetation in the town, such as the grass in parks, road medians, and browsing on low branches of the many trees. Name The name ''gemsbok'' is from Afrikaans, which itself is from the Dutch word of the same spelling, meaning "male chamois", composed of (“chamois”) + (“buck, male goat”). The Dutch is further from German ("chamois"). Although some superficial similarities in appearance (especially in the facial pattern) are noticed, the chamois and t ...

Arabian Oryx Reintroduction
The Arabian oryx (''Oryx leucoryx''), also called the white oryx, was extinct in the wild as of 1972, but was reintroduced to the wild starting in 1982. Initial reintroduction was primarily from two herds: the "World Herd" originally started at the Phoenix Zoo in 1963 from only nine oryx and the Saudi Arabian herd started in 1986 from private collections and some "World Herd" stock by the Saudi National Wildlife Research Center (NWRC). As of 2009 there have been reintroductions in Oman, Saudi Arabia, Israel, the United Arab Emirates, and Jordan, and as of 2013 the IUCN Red List classifies the species as vulnerable. Decline of a species The Arabian oryx was known to be in decline since the early 1900s in the Arabian Peninsula. By the 1930 there were two separate populations isolated from each other. In 1960, Lee Talbot reported that Arabian oryx appeared to be extinct in its former range along the southern edge of Ar-Rub' al-Khali. He believed that any oryx still existing would ...

Oryx Beisa
The East African oryx (''Oryx beisa''), also known as the beisa is a species of antelope from East Africa. It has two subspecies: the common beisa oryx (''Oryx beisa beisa'') found in steppe and semidesert throughout the Horn of Africa and north of the Tana River, and the fringe-eared oryx (''Oryx beisa callotis'') south of the Tana River in southern Kenya and parts of Tanzania. In the past, some taxonomists considered it a subspecies of the gemsbok (''Oryx gazella''), but they are genetically distinct; the diploid chromosome count is 56 for the beisa and 58 for the gemsbok. The species is listed as Endangered by the IUCN. Description The East African oryx stands just over a metre at the shoulder and weighs around . It has a grey coat with a white underside, separated from the grey by a stripe of black, with black stripes where the head attaches to the neck, along the nose, and from the eye to the mouth and on the forehead. The mane is small and chestnut-coloured; the ringed h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species Reintroduction
Species reintroduction is the deliberate release of a species into the wild, from captivity or other areas where the organism is capable of survival. The goal of species reintroduction is to establish a healthy, genetically diverse, self-sustaining population to an area where it has been extirpated, or to augment an existing population. Species that may be eligible for reintroduction are typically threatened or endangered in the wild. However, reintroduction of a species can also be for pest control; for example, wolves being reintroduced to a wild area to curb an overpopulation of deer. Because reintroduction may involve returning native species to localities where they had been extirpated, some prefer the term "reestablishment". Humans have been reintroducing species for food and pest control for thousands of years. However, the practice of reintroducing for conservation is much younger, starting in the 20th century.

Extinct In The Wild
A species that is extinct in the wild (EW) is one that has been categorized by the International Union for Conservation of Nature as known only by living members kept in captivity or as a naturalized population outside its historic range due to massive habitat loss. Examples Examples of species and subspecies that are extinct in the wild include: *Alagoas curassow (last unconfirmed sighting reported in the late 1980s, listed extinct in the wild since 1994) *Beloribitsa * Cachorrito de charco palmal (last seen in 1994, listed extinct in the wild since 1996) * Christmas Island blue-tailed skink (listed extinct in the wild since 2014) *Dabry's sturgeon (listed extinct in the wild since 2022) * Escarpment cycad (listed extinct in the wild since 2006) *Franklinia (last seen in 1803, listed extinct in the wild since 1998) *Golden skiffia (listed extinct in the wild since 1996) *Guam kingfisher (listed extinct in the wild since 1986) *Hawaiian crow or ʻalalā (last seen in 2002, li ...

Antelope
The term antelope is used to refer to many species of even-toed ruminant that are indigenous to various regions in Africa and Eurasia. Antelope comprise a wastebasket taxon defined as any of numerous Old World grazing and browsing hoofed mammals belonging to the family Bovidae of the order Artiodactyla. A stricter definition, also known as the "true antelopes," includes only the genera ''Gazella'', ''Nanger'', ''Eudorcas'' and ''Antilope''. One North American species, the pronghorn, is colloquially referred to as the "American antelope," but it belongs to a different family from the African and Eurasian antelopes. A group of antelope is called a herd. Unlike deer antlers, which are shed and grown annually, antelope horns grow continuously. Etymology The English word "antelope" first appeared in 1417 and is derived from the Old French ''antelop'', itself derived from Medieval Latin ''ant(h)alopus'', which in turn comes from the Byzantine Greek word ἀνθόλοψ, ''anthó ...

Captive Breeding
Captive breeding, also known as captive propagation, is the process of plants or animals in controlled environments, such as wildlife reserves, zoos, botanic gardens, and other conservation facilities. It is sometimes employed to help species that are being threatened by the effects of human activities such as climate change, habitat loss, fragmentation, over hunting or fishing, pollution, predation, disease, and parasitism. For many species, relatively little is known about the conditions needed for successful breeding. Information about a species' reproductive biology may be critical to the success of a captive breeding program. In some cases a captive breeding program can save a species from extinction, but for success, breeders must consider many factors—including genetic, ecological, behavioral, and ethical issues. Most successful attempts involve the cooperation and coordination of many institutions. History Captive breeding techniques began with the first human do ...
