Grivet
The grivet (''Chlorocebus aethiops'') is an Old World monkey with long white tufts of hair along the sides of its face. Some authorities consider this and all of the members of the genus ''Chlorocebus'' to be a single species, ''Cercopithecus aethiops''. As here defined, the grivet is restricted to Ethiopia, Sudan, Djibouti, and Eritrea. In the southern part of its range, it comes into contact with the closely related vervet monkey (''C. pygerythrus'') and Bale Mountains vervet (''C. djamdjamensis''). Hybridization between them is possible, and may present a threat to the vulnerable Bale Mountains vervet. Unlike that species, the grivet is common and rated as least concern by the IUCN. Physical description The grivet's facial skin, hands, and feet are black. The face has a white line above the eyes. It has long, white whiskers on the cheeks. The fur on the back has an olive color, while the front is white. The skin on the stomach has a blue tint. The fur has a bristly feel. The ...

Bale Mountains Vervet
The Bale Mountains vervet (''Chlorocebus djamdjamensis'') is a terrestrial Old World monkey endemic to Ethiopia, found in the bamboo forests of the Bale Mountains. All species in ''Chlorocebus'' were formerly in the genus '' Cercopithecus''. The Bale Mountains vervet is one of the least-known primates in Africa. They avoid tree-dominated and bushland areas as their habitat. These monkeys mainly reside in the bamboo forest (Odubullu Forest) of the Bale Mountains due their dietary specialization on bamboo, but other factors, such as climate, forest history, soil quality, and disease, are likely to play a role in their choice to inhabit this area. The Bale Mountains vervet have a very quiet behavior and tend to flee when encountering a human being. It is also known as the Bale monkey and Bale Mountain grivet. Taxonomy The Bale monkey is a member of genus ''Chlorocebus'', along with six sister species. All members of ''Chlorocebus'' were formerly considered to be part of '' Cerc ...

Vervet Monkey
The vervet monkey (''Chlorocebus pygerythrus''), or simply vervet, is an Old World monkey of the family Cercopithecidae native to Africa. The term "vervet" is also used to refer to all the members of the genus '' Chlorocebus''. The five distinct subspecies can be found mostly throughout Southern Africa, as well as some of the eastern countries. These mostly herbivorous monkeys have black faces and grey body hair color, ranging in body length from about for females, to about for males. In addition to behavioral research on natural populations, vervet monkeys serve as a nonhuman primate model for understanding genetic and social behaviors of humans. They have been noted for having human-like characteristics, such as hypertension, anxiety, and social and dependent alcohol use. Vervets live in social groups ranging from 10 to 70 individuals, with males moving to other groups at the time of sexual maturity. Studies done on vervet monkeys involve their communication and alarm cal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chlorocebus
''Chlorocebus'' is a genus of medium-sized primates from the family of Old World monkeys. Six species are currently recognized, although some people classify them all as a single species with numerous subspecies. Either way, they make up the entirety of the genus ''Chlorocebus''. Confusingly, the terms "vervet monkey" and "green monkey" are sometimes used to refer to the whole genus ''Chlorocebus'', though they also refer more precisely to species ''vervet monkey, Chlorocebus pygerythrus'' and ''green monkey, Chlorocebus sabaeus'', respectively, neither of which is the type species for ''Chlorocebus''. This article uses the term ''Chlorocebus'' consistently for the genus and the common names only for the species. The native range (biology), range of these monkeys is sub-Saharan Africa from Senegal and Ethiopia south to South Africa. However, in previous centuries, a number of them were taken as pets by early Caribbean settlers and slave traders, and were transported across the At ...

Estrus
The estrous cycle (, originally ) is a set of recurring physiological changes induced by reproductive hormones in females of mammalian subclass Theria. Estrous cycles start after sexual maturity in females and are interrupted by anestrous phases, otherwise known as "rest" phases, or by pregnancies. Typically, estrous cycles repeat until death. These cycles are widely variable in duration and frequency depending on the species.Bronson, F. H., 1989. Mammalian Reproductive Biology. University of Chicago Press, Chicago, IL, USA. Some animals may display bloody vaginal discharge, often mistaken for menstruation. Many mammals used in commercial agriculture, such as cattle and sheep, may have their estrous cycles artificially controlled with hormonal medications for optimum productivity. The male equivalent, seen primarily in ruminants, is called rut. Differences from the menstrual cycle Mammals share the same reproductive system, including the regulatory hypothalamic system tha ...

Bushmeat
Bushmeat is meat from wildlife species that are Hunting, hunted for human consumption. Bushmeat represents a primary source of animal protein and a cash-earning commodity in poor and rural communities of humid tropical forest regions of the world. The numbers of animals killed and traded as bushmeat in 1994 in West Africa, West and Central Africa were thought to be unsustainable. By 2005, commercial harvesting and trading of bushmeat was considered a threat to biodiversity. As of 2016, 301 terrestrial mammals were threatened with extinction due to hunting for bushmeat including non-human primates, even-toed ungulates, bats, Diprotodontia, diprotodont marsupials, rodents and carnivores occurring in developing country, developing countries. Bushmeat provides increased opportunity for transmission of several zoonotic viruses from animal hosts to humans, such as ''Ebolavirus'' and HIV.

Ancient Egypt
Ancient Egypt () was a cradle of civilization concentrated along the lower reaches of the Nile River in Northeast Africa. It emerged from prehistoric Egypt around 3150BC (according to conventional Egyptian chronology), when Upper and Lower Egypt were amalgamated by Menes, who is believed by the majority of List of Egyptologists, Egyptologists to have been the same person as Narmer. The history of ancient Egypt unfolded as a series of stable kingdoms interspersed by the "Periodization of ancient Egypt, Intermediate Periods" of relative instability. These stable kingdoms existed in one of three periods: the Old Kingdom of Egypt, Old Kingdom of the Early Bronze Age; the Middle Kingdom of Egypt, Middle Kingdom of the Middle Bronze Age; or the New Kingdom of Egypt, New Kingdom of the Late Bronze Age. The pinnacle of ancient Egyptian power was achieved during the New Kingdom, which extended its rule to much of Nubia and a considerable portion of the Levant. After this period, Egypt ...

Hamadryas Baboon
The hamadryas baboon (''Papio hamadryas'' ; gawina;Aerts 2019 , Ar Robbaḥ) is a species of baboon within the Old World monkey family. It is the northernmost of all the baboons, being native to the Horn of Africa and the southwestern region of the Arabian Peninsula. These regions provide habitats with the advantage for this species of fewer natural predators than central or southern Africa where other baboons reside. The hamadryas baboon was a sacred animal to the ancient Egyptians and appears in various roles in ancient Egyptian religion, hence its alternative name of 'sacred baboon'.Swedell 2015 Description The hamadryas baboon shows differences in coloration among adults with males having a pronounced silver-white mane and mantle, which they develop at around the age of ten years, while the females are capeless and brown all over and have reddish to dark brown faces. They are also Sexual dimorphism in non-human primates, sexually dimorphic in size, and males are nearly twic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patas Monkey
The common patas monkey (''Erythrocebus patas''), also known as the hussar monkey, is a ground-dwelling monkey distributed over semi-arid areas of West Africa, and into East Africa. Taxonomy There is some confusion surrounding if there are valid subspecies, with some listing four, others three, and others listing two: the western ''Erythrocebus patas patas'' (with a black nose) and the eastern ''E. patas pyrrhonotus'' (with a white nose). However, it was later discovered that the nose colour used to separate these subspecies could change to white during pregnancy in females, as well as in general as animals aged, and ''E. patas pyrrhonotus'' in Kenya often did not have white noses, thus ''Mammal Species of the World'' has classified ''E. patas'' as a monotypic species. The genus status of the species has previously been in flux. Colin Groves first argued the species was closely related to '' Cercopithecus aethiops'' in 1989, based on anatomical morphology.

Olive Baboon
The olive baboon (''Papio anubis''), also called the Anubis baboon, is a member of the family Cercopithecidae Old World monkeys. The species is the most wide-ranging of all baboons, being native to 25 countries throughout Africa, extending from Mali eastward to Ethiopia and Tanzania. Isolated populations are also present in some mountainous regions of the Sahara. It inhabits savannahs, steppes, and forests. The common name is derived from its coat colour, which is a shade of green-grey at a distance. A variety of communications, vocal and non-vocal, facilitate a complex social structure. Characteristics The olive baboon is named for its coat, which, at a distance, is a shade of green-grey. At closer range, its coat is multicoloured, due to Agouti (coloration), rings of yellow-brown and black on the hairs. The hair on the baboon's face is coarser and ranges from dark grey to black. This coloration is shared by both sexes, although males have a mane of longer hair that tapers dow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quadruped
Quadrupedalism is a form of locomotion in which animals have four legs that are used to bear weight and move around. An animal or machine that usually maintains a four-legged posture and moves using all four legs is said to be a quadruped (from Latin ''quattuor'' for "four", and ''pes'', ''pedis'' for "foot"). Quadruped animals are found among both vertebrates and invertebrates. Quadrupeds vs. tetrapods Although the words ‘quadruped’ and ‘tetrapod’ are both derived from terms meaning ‘four-footed’, they have distinct meanings. A tetrapod is any member of the taxonomic unit Tetrapoda (which is defined by descent from a specific four-limbed ancestor), whereas a quadruped actually uses four limbs for locomotion. Not all tetrapods are quadrupeds and not all quadrupedal animals are tetrapods; some arthropods are adapted for four-footed locomotion, such as the raptorial Mantodea, or mantises, and the Nymphalidae, or brush-footed butterflies—the largest butterfly f ...
