Animal populations with impoverished genetic diversity are inherently less able to adapt to changes in their environments (such as climate change, disease outbreaks, habitat change, etc.). The isolation of the four remaining small bongo populations, which themselves would appear to be in decline, means a substantial amount of genetic material ...
Though not an antelope, it is known colloquially in North America as the American antelope, prong buck, pronghorn antelope and prairie antelope, [5] because it closely resembles the antelopes of the Old World and fills a similar ecological niche due to parallel evolution. [6] It is the only surviving member of the family Antilocapridae. [7]

[7] The ears, tipped with black, are 15–18 cm (5.9–7.1 in) long. [2]
Electron micrograph of Bluetongue virus, scale bar = 50 nm. Bluetongue (BT) disease is a noncontagious, arthropod-borne viral disease affecting ruminants, [1] primarily sheep and other domestic or wild ruminants, including cattle, yaks, [2] goats, buffalo, deer, dromedaries, and antelope. [3]
The hirola (Beatragus hunteri), also called the Hunter's hartebeest or Hunter's antelope, is a critically endangered antelope species found as of now, only in Kenya along the border of Somalia. [3] It was first described by the big game hunter and zoologist H.C.V. Hunter in 1888.
The nyala is a spiral-horned and middle-sized antelope, between a bushbuck and a kudu. [16] It is considered the most sexually dimorphic antelope. [2] The nyala is typically between 135–195 cm (53–77 in) in head-and-body length. [2] The male stands up to 110 cm (43 in), the female is up to 90 cm (3.0 ft) tall.
The greater kudu (Tragelaphus strepsiceros) is a large woodland antelope, found throughout eastern and southern Africa.Despite occupying such widespread territory, they are sparsely populated in most areas due to declining habitat, deforestation, and poaching. [2]
