Mountain Ground Squirrel
The mountain ground squirrel (''Geosciurus princeps'') is a rodent that is native to southwestern Angola, western Namibia, and western South Africa. It is also known as the Kaoko ground squirrel or the Damara ground squirrel. It is the closest relative of the Cape ground squirrel (Latin name ''Geosciurus inauris''), which is so similar in appearance that the two are difficult to distinguish in the field. Both species have long bushy black and white tails with a white stripe from the shoulder towards the rump. ''Geosciurus princeps'' is slightly larger, on average, than ''G. inauris'', although there is considerable overlap in body size. Differences in skull morphology also distinguish the two species, and the incisors are yellow to orange rather than white as in ''G. inauris''. Distribution The mountain ground squirrel is restricted to a narrow band of the southwest arid region of Africa from southern Angola to southern Namibia and as far south as Richtersveld National Park. ...

Oldfield Thomas
Michael Rogers Oldfield Thomas (21 February 1858 – 16 June 1929) was a British zoologist. Career Thomas worked at the Natural History Museum, London, Natural History Museum on mammals, describing about 2,000 new species and subspecies for the first time. He was appointed to the museum secretary's office in 1876, transferring to the zoological department in 1878. In 1891, Thomas married Mary Kane, daughter of Sir Andrew Clark, 1st Baronet, Sir Andrew Clark, heiress to a small fortune, which gave him the finances to hire mammal collectors and present their specimens to the museum. He also did field work himself in Western Europe and South America. His wife shared his interest in natural history, and accompanied him on collecting trips. In 1896, when William Henry Flower took control of the department, he hired Richard Lydekker to rearrange the exhibitions, allowing Thomas to concentrate on these new specimens. Thomas viewed his taxonomy efforts from the scope of British impe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape Ground Squirrel
The Cape ground squirrel or South African ground squirrel (''Geosciurus inauris'') is found in most of the drier parts of southern Africa from South Africa, through to Botswana, and into Namibia, including Etosha National Park. The name ''Cape'' ground squirrel is somewhat misleading as it actually has a much wider area of habitation. This common name may have been arrived at to distinguish it from a tree squirrel (the eastern grey squirrel) found around Cape Town, which was imported from Europe by Cecil John Rhodes. The species has also been known as the fan-tailed squirrel. Description The Cape ground squirrel has black skin with a coat made of short stiff hairs without underfur. The fur is cinnamon on the back while the face, underbelly, sides of neck and ventral sides of limbs are white.Skurski, D., J. Waterman. 2005. "Xerus inauris", ''Mammalian Species'' 781:1-4. The sides of its body each have a white stripe that stretches from the shoulders to the thighs. The eye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Described In 1929
A mammal () is a vertebrate animal of the class Mammalia (). Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors diverged in the Carboniferous Period over 300 million years ago. Around 6,640 extant species of mammals have been described and divided into 27 orders. The study of mammals is called mammalogy. The largest orders of mammals, by number of species, are the rodents, bats, and eulipotyphlans (including hedgehogs, moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including cats, dogs, and seals). Mammals are the only living members of Synapsida; this clade, together with Sauropsida (reptiles and birds), constitutes the large ...

Mammals Of South Africa
The wildlife of South Africa consists of the flora and fauna of this country in Southern Africa. The country has a range of different habitat types and an ecologically rich and diverse wildlife, vascular plants being particularly abundant, many of them endemic to the country. There are few forested areas, much savanna grassland, semi-arid Karoo vegetation and the fynbos of the Cape Floristic Region. Famed for its national parks and big game, 297 species of mammal have been recorded in South Africa, as well as 849 species of bird and over 20,000 species of vascular plants. Geography South Africa is located in subtropical southern Africa, lying between 22°S and 35°S. It is bordered by Namibia, Botswana and Zimbabwe to the north, by Mozambique and Eswatini (Swaziland) to the northeast, by the Indian Ocean to the east and south, and the Atlantic Ocean to the west, the coastline extending for more than . The interior of the country consists of a large, nearly flat, plateau with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Allogrooming
Social grooming is a behavior in which social animals, including humans, clean or maintain one another's bodies or appearances. A related term, allogrooming, indicates social grooming between members of the same species. Grooming is a major social activity and a means by which animals who live in close proximity may bond, reinforce social structures and family links, and build companionship. Social grooming is also used as a means of conflict resolution, maternal behavior, and reconciliation in some species. Mutual grooming typically describes the act of grooming between two individuals, often as a part of social grooming, pair bonding, or a precoital activity. Evolutionary advantages There are a variety of proposed mechanisms by which social grooming behavior has been hypothesized to increase fitness. These evolutionary advantages may come in the form of health benefits including reduction in disease transmission and stress levels, maintenance of social structures, and d ...

Play (animal Behaviour)
Play is a range of Motivation#Intrinsic and extrinsic, intrinsically motivated activities done for recreation. Play is commonly associated with children and juvenile-level activities, but may be engaged in at any life stage, and among other higher-functioning animals as well, most notably mammals and birds. Play is often interpreted as frivolous; yet the player can be intently focused on their objective, particularly when play is structured and goal-oriented, as in a game. Accordingly, play can range from relaxed, free-spirited, spontaneous, and frivolous to planned or even compulsive. Play is not just a pastime activity; it has the potential to serve as an important tool in numerous aspects of daily life for adolescents, adults, and cognitively advanced non-human species (such as primates). Not only does play promote and aid in physical development (such as hand-eye coordination), but it also aids in cognitive development and social skills, and can even act as a stepping stone i ...

Diurnality
Diurnality is a form of plant and ethology, animal behavior characterized by activity during daytime, with a period of sleeping or other inactivity at night. The common adjective used for daytime activity is "diurnal". The timing of activity by an animal depends on a variety of environmental factors such as the temperature, the ability to gather food by sight, the risk of predation, and the time of year. Diurnality is a cycle of activity within a 24-hour period; cyclic activities called circadian rhythms are endogenous cycles not dependent on external cues or environmental factors except for a zeitgeber. Animals active during twilight are crepuscular, those active during the night are nocturnal and animals active at sporadic times during both night and day are cathemerality, cathemeral. Plants that open their flowers during the daytime are described as diurnal, while those that bloom during nighttime are nocturnal. The timing of flower opening is often related to the time at whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rodent
Rodents (from Latin , 'to gnaw') are mammals of the Order (biology), order Rodentia ( ), which are characterized by a single pair of continuously growing incisors in each of the upper and Mandible, lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/ricochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include Mouse, mice, rats, squirrels, prairie dogs, porcupines, beavers, Cavia, guinea pigs, and hamsters. Once included wi ...

Richtersveld National Park
The Richtersveld is a desert landscape characterised by rugged kloofs and high mountains, situated in the north-western corner of South Africa’s Northern Cape province. It is full of changing scenery from flat, sandy, coastal plains, to craggy sharp mountains of volcanic rock and the lushness of the Orange River, which forms the border with neighboring Namibia. The area ranges in altitude from sea level, to at Cornellberg. Located in the north-western side of the Northern Cape province in South Africa, the Richtersveld is regarded as the only arid biodiversity hotspot on earth and the majority of the area is inscribed on UNESCO's World Heritage List due to its cultural values. The Nama people of Richtersveld claimed title to their traditional land and set aside this conservancy for future research and tourism. The northern part of the area was proclaimed in 1991 after 18 years of negotiations between the National Parks Board and the local Nama people who continue to live an ...
