Cape ground squirrel (Xerus inauris) Appearance The Cape ground squirrel is a rodent endemic to South Africa. Cape ground squirrels have a mutualistic relationship with meerkats. They can also be found in scrub along pans, on floodplains and in agricultural areas. Small mammals that inhabit this region, such as the Cape ground squirrel (Xerus inauris), exhibit typical arid adaptations including a low resting metabolic rate, a high thermal conductance and a concentrated urine [26,27]. A colony of Cape ground squirrels responds to the presence of a snake with mobbing behavior. They are burrowing animals that dig and live in clusters of burrows averaging around 700 square metres (7,500 sq ft) with 2-100 entrances. The Cape ground squirrel, Xerus inauris, a diurnally active inhabitant of hot arid regions of southern Africa, reduces environmental heat load by using its bushy tail as a portable parasol. Cape ground squirrels live mainly in arid or semiarid areas. Ground squirrels can be found throughout Southern Africa, in South Africa, Botswana and Namibia. The fur is cinnamon on the back while the face, underbelly, sides of neck and ventral sides of limbs are white. Caring for the young seems to be a community duty, since this task is shared by various females in a colony. The prominent eyes are circled with white and the muzzle and feet are also white. Gray fur forms a cape over the sides of the head and shoulders. Each side of their body has a white stripe that stretches from the shoulders to the thighs. They prefer to live in veldand grasslands with hard ground. Nev… Some species have dark and light stripes that run along the body while others show up small light spots with unique contrasting patches. Evidence suggests that sperm competition is an important aspect of male reproductive success in this species. At midday, squirrels must frequently retreat to their burrows as Te of tail-shaded animals then also exceeds 40 C.

The Cape ground squirrel is red-brown in color, with paler undersides and face. The most evident being their long bushy tail. males and females generally living in separate groups, some. Although male-biased dispersal is the norm, with. reflect an adaptation in the Cape ground squirrel to avoid. This involves … Cape Ground Squirrel [Xerus inauris] Appearance The Cape Ground Squirrel is a rodent endemic to South Africa. A thin white line runs from the shoulder to the hip on each side of the body. They have got slender bushy tail and a cylindrical hairless body. The Cape ground squirrel (Xerus inauris) is a highly social species inhabiting open areas in arid regions across southern Africa (Waterman 1995). Males have a scrotum that’s 20% of their body length (excluding the tail) and their penis is more than twice as long. Kruger National Park - South African Safari. Dispersal of offspring to colonies in adjacent territories only takes place after two years. 51x41cm Canvas Print. That’s a Cape ground squirrel and the image isn’t a fake. In turn, Cape ground squirrels provide burrows. Young are altricial and naked at birth. It has a coarse, cinnamon coloured coat with a white stripe running down either side of its body. Time and ecological resilience: can diurnal animals compensate for climate change by shifting to nocturnal activity? Although females are reproductively mature at six months, only the ones older than one year are allowed to breed. … This dispersal pattern allows for the formation of new groups and enhances gene flow. This gray cape may have a protective function, breaking up the animal's body outline and making it more difficult for a predator to spot (see photo). It measures 450 mm in length and weighs up to 1 kg. Meerkat alarm calls warn squirrels of potential danger from predators. Simultaneously, the thermoregulatory behavior of a free-living colony of squirrels was observed.

White underparts and the distinctive bushy fan-like tail have black based, white tipped hairs. They are active year-round and forage during the heat of the day. Not only is this adaptation comfortable and potentially life-saving in the hot, harsh, dry grassland and semi-desert conditions in which they occur, the ability to bring shelter with it gives Cape Ground Squirrels a survive and thrive edge over other species of herbivores. During late spring in the southern Kalahari, operative environmental temperature (Te) was measured on thermal mannequins of differing posture and tail orientation. The tail is raised to shade the body and the squirrels turn their backs to the sun whenever Te exceeds approximately 40 C. The shade provided by the tail reduces Te by over 5 C and allows squirrels to extend greatly their periods of continuous surface foraging (up to 7 h instead of 3 h). They are active year-round and forage during the heat of the day. Cape ground squirrels also increase visibility when they remove plants from the surface while they eat. South African ground squirrel, Cape ground squirrel (Geosciurus inauris, Xerus inauris), walking over soil ground, South Africa, Kgalagadi Transfrontier National Park Cape ground squirrels (Xerus inauris) mobbing a Cape cobra (Naja nivea) that had come too close to … Energetic costs of parasitism in the Cape ground squirrel Xerus inauris.
