The ecology and breeding biology of the Gemsbok (Oryx Gazella Gazella) (Linnaeus, 1785) in the Hester Malan Nature Reserve

Abstract

The study investigates certain ecological and behavioral adaptations of the Gemsbok in the Hester Malan Nature Reserve. Gemsbok breeding system was found to be a seasonal with a high reproductive potential, being able to produce a calf every nine months. The social organization was characterized by a territorial system with the size of the territories among the largest found in ungulates. Seasonal variations in sizes of mixed herds are related to the availability and nutritional value of food plants, factors which also influenced their feeding pattern. Opportunistic feeders as a result of their restricted existence. Variations in activity patterns are discussed in relation to endogenous and exogenous factors. The management implications of all these factors are examined.
