The gemsbok is an oryx with bold black markings on its face and body.
Its gray-to-tan body contrasts with black facial markings and a white muzzle. The long horns carry ring-like ridges.
Gemsbok adjust when and where they are active in hot surroundings. In Botswana’s Kalahari, they increased the proportion of activity occurring at night in hot seasons and selected cooler surroundings during hot daytime periods.
Researchers fitted free-ranging females with devices recording body temperature, activity and location. Detailed analyses focused on December 2013–November 2014, using temperature and microclimate records from five gemsbok and activity records from three. Comparing a collar thermometer with an identical sun-exposed thermometer revealed the thermal environments selected by each animal.
During hot seasons, animals sometimes occupied environments about ten degrees cooler than the sun-exposed reference. Body temperature stayed within a relatively narrow daily range for much of the year, with a wider range during the hot-dry season. The authors interpreted shade seeking and nighttime activity as ways of coping with these surroundings. Physiology and choices of place and time worked together.
An extinction-risk assessment has not been added yet.
The 2016 regional assessment for South Africa, Lesotho and Swaziland identifies habitat degradation through overgrazing and the maintenance of genetic diversity in isolated gemsbok subpopulations as management concerns. On small private properties, fences restrict natural movements. The assessment recommends maintaining forage and water resources and monitoring population trends and genetic diversity. It also lists habitat connections permitting natural movements as a conservation intervention.
