The gemsbok (Oryx gazella), or South African oryx, is a large antelope in the genus Oryx. It is endemic to the dry and barren regions of Botswana , Namibia , South Africa and (parts of) Zimbabwe , mainly inhabiting the Kalahari and Namib Deserts , areas in which it is supremely adapted for survival.
Females all but cease other activities in favor of vigilance. They move slowly in the direction of the fawn's hiding spot, stopping frequently to scan the environment. Several females in our observations engaged in "sham" feeding behavior, in which they lowered their heads to the ground as if to feed before quickly raising them back up to scan.
The dama gazelle (Nanger dama), also known as the addra gazelle or mhorr gazelle, is a species of gazelle.It lives in Africa, in the Sahara desert and the Sahel.A critically endangered species, it has disappeared from most of its former range due to overhunting and habitat loss, and natural populations only remain in Chad, Mali, and Niger.
Acclimatization or acclimatisation (also called acclimation or acclimatation) is the process in which an individual organism adjusts to a change in its environment (such as a change in altitude, temperature, humidity, photoperiod, or pH), allowing it to maintain fitness across a range of environmental conditions.

[53] [55] This is to compensate for the low oxygen environment. This adaptation is associated with developmental patterns such as high birth weight, increased lung volumes, increased breathing, and higher resting metabolism. [56] [57] The genome of Tibetans provided the first clue to the molecular evolution of high-altitude adaptation in 2010. [58]
Adaptationism is an approach to studying the evolution of form and function. It attempts to frame the existence and persistence of traits, assuming that each of them arose independently and improved the reproductive success of the organism's ancestors.
Foraging and feeding is the major activity throughout the day; females appear to spend longer time in feeding. The gerenuk may expose itself to rain, probably to cool its body. [17] The social structure consists of small herds of two to six members. Herds typically comprise members of a single sex, though female herds additionally have juveniles.
