59-545: 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 Chlorocebus pygerythrus and Chlorocebus sabaeus , respectively, neither of which

118-557: A species : see Botanical name and Specific name (zoology) . The rules for the scientific names of organisms are laid down in the nomenclature codes , which allow each species a single unique name that, for animals (including protists ), plants (also including algae and fungi ) and prokaryotes ( bacteria and archaea ), is Latin and binomial in form; this contrasts with common or vernacular names , which are non-standardized, can be non-unique, and typically also vary by country and language of usage. Except for viruses ,

177-482: A complex biomarker of aging - was developed for Chlorocebus sabaeus in several variants: tissue-specific clocks for brain cortex, blood, and liver; multitissue clock; and human-sabaeus monkey clocks. Genus The composition of a genus is determined by taxonomists . The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including

236-501: A continuous cell line derived from epithelial cells of the African green monkey kidney , and are widely used for research in immunology and infectious disease . Similar cell lines include buffalo green monkey kidney and BS-C-1. Chlorocebus monkeys are an important model organism for studies of AIDS, microbiome, development, neurobehavior, neurodegeneration, metabolism and obesity. A genome of chlorocebus monkey ( Chlorocebus sabaeus )

295-643: A later homonym of a validly published name is a nomen illegitimum or nom. illeg. ; for a full list refer to the International Code of Nomenclature for algae, fungi, and plants and the work cited above by Hawksworth, 2010. In place of the "valid taxon" in zoology, the nearest equivalent in botany is " correct name " or "current name" which can, again, differ or change with alternative taxonomic treatments or new information that results in previously accepted genera being combined or split. Prokaryote and virus codes of nomenclature also exist which serve as

354-621: A long time and redescribed as new by a range of subsequent workers, or if a range of genera previously considered separate taxa have subsequently been consolidated into one. For example, the World Register of Marine Species presently lists 8 genus-level synonyms for the sperm whale genus Physeter Linnaeus, 1758, and 13 for the bivalve genus Pecten O.F. Müller, 1776. Within the same kingdom, one generic name can apply to one genus only. However, many names have been assigned (usually unintentionally) to two or more different genera. For example,

413-524: A notable exception. When chimpanzees from different troops come together, there is often an exciting, friendly encounter lasting several hours, following which, some of the adult females switch groups. Apparently, they are seeking new mates. Occasionally, however, contact between communities of the comparatively unpredictable chimpanzees will develop into genocidal violence. Interactions within non-human primate communities are usually unlimited. Subgroups are rarely closed from group interaction. All members of

472-407: A number of different mates. Multi-male groups are common among semi-terrestrial primates, like savanna baboons, macques, colobus and some New World monkeys. A factor influencing the number of males in a group may be to avoid predators, as a study found significant positive correlations between the number of males in a group and the predation risk where the group lived. Another study found that there

531-434: A number of multi-male societies in two general contexts: when new immigrants rise to the alpha position in the male dominance hierarchy; or when coalitionary cohorts of alien males collectively replace the entire male membership of a group. In some multi-male groups, the costs for infanticidal males seem likely to be high, since other resident males might defend the victim, and the benefits seem likely to be low because of

590-415: A particular locale and rarely migrate outside of their home range. This aloofness from other troops prevents high concentrations of individuals, which could result in rapid depletion of local resources. Communities usually avoid each other and are aggressive towards outsiders. As a result, social interactions between members of different troops are usually very rare, especially for females. Chimpanzees are

649-409: A reference for designating currently accepted genus names as opposed to others which may be either reduced to synonymy, or, in the case of prokaryotes, relegated to a status of "names without standing in prokaryotic nomenclature". An available (zoological) or validly published (botanical) name that has been historically applied to a genus but is not regarded as the accepted (current/valid) name for

708-542: A result, the population numbers in troops are declining in urban areas to an average of between 15 and 25 individuals, with many troops disappearing altogether. The African green monkey has been the focus of much scientific research since the 1950s, and cell lines derived from its tissues are still used today to produce vaccines for polio and smallpox . Chlorocebus species are also important in studying high blood pressure and AIDS. Unlike most other nonhuman primates, they naturally develop high blood pressure . In Africa,

767-542: A seasonal resource, varied to cope with changes in food availability. On the island of Saint Kitts , they will commonly steal brightly coloured alcoholic drinks left behind by tourists on the beach. Many tourists have also found out these monkeys will deliver a powerful bite if they are cornered or threatened. In Africa, the documented attacks by these monkeys are extremely rare when compared with dog attacks, in spite of living very closely with humans and often being threatened by humans and their dogs. To signal mating readiness,

826-427: A taxon; however, the names published in suppressed works are made unavailable via the relevant Opinion dealing with the work in question. In botany, similar concepts exist but with different labels. The botanical equivalent of zoology's "available name" is a validly published name . An invalidly published name is a nomen invalidum or nom. inval. ; a rejected name is a nomen rejiciendum or nom. rej. ;

885-455: A total of c. 520,000 published names (including synonyms) as at end 2019, increasing at some 2,500 published generic names per year. "Official" registers of taxon names at all ranks, including genera, exist for a few groups only such as viruses and prokaryotes, while for others there are compendia with no "official" standing such as Index Fungorum for fungi, Index Nominum Algarum and AlgaeBase for algae, Index Nominum Genericorum and

944-434: A type of social organization where the group contains more than one adult male, more than one adult female, and offspring. This structure is characterized by group living (as opposed to solitary), polygynandrous, and strong reproductive competition among males, which could result in an uneven division of male reproductive success (i.e. reproductive skew). There are no stable heterosexual bonds as both males and females have

1003-476: Is a primary determinant of female-female aggression and thus female social relationships. In social systems with promiscuous breeding like multi-male groups, polygamy causes possible ambiguity in parentage. Since kin discrimination between fathers and infants could be more difficult, it has been theorized in the past that the incidence of male care of infants in polygamous primate groups may be less in multi-male groups than in monogamous primate groups. However, in

1062-422: Is a significant positive correlation between the number of males per female and the estimated predation rate. This finding may reflect the adaptive advantage to females of tolerating multiple males that provide vigilance and predator defense. There are two theories about the advantages of multi-male groups against predators: (1) males are more vigilant or (2) males more actively engage in the physical defense of

1121-410: Is bluish. Males have a blue scrotum and red penis . The monkeys are sexually dimorphic , wild adult males range from 42 to 59 cm (17 to 23 in) and females are 30 to 49.5 cm (11.8 to 19.5 in), including a tail measuring 30 to 50 cm (12 to 20 in). Males weigh from 3.9 to 8 kg (8.6 to 17.6 lb) and females weigh from 3.4 to 5.3 kg (7.5 to 11.7 lb). Unlike

1180-596: Is discouraged by both the International Code of Zoological Nomenclature and the International Code of Nomenclature for algae, fungi, and plants , there are some five thousand such names in use in more than one kingdom. For instance, A list of generic homonyms (with their authorities), including both available (validly published) and selected unavailable names, has been compiled by the Interim Register of Marine and Nonmarine Genera (IRMNG). The type genus forms

1239-466: Is reports the least. The variation in male paternal care may be due to the differences in the importance of male care to infant survival, the differences in male confidence of paternity, which may relate to seasonal breeding patterns and the presence or absence of conspicuous signs of female ovulation, and the relative costs and benefits of other opportunities available to males (e.g. mating opportunities). Significant male infanticide has been documented in

1298-460: Is somewhat arbitrary. Although all species within a genus are supposed to be "similar", there are no objective criteria for grouping species into genera. There is much debate among zoologists about whether enormous, species-rich genera should be maintained, as it is extremely difficult to come up with identification keys or even character sets that distinguish all species. Hence, many taxonomists argue in favor of breaking down large genera. For instance,

1357-474: Is the type species , and the generic name is permanently associated with the type specimen of its type species. Should the specimen turn out to be assignable to another genus, the generic name linked to it becomes a junior synonym and the remaining taxa in the former genus need to be reassessed. In zoological usage, taxonomic names, including those of genera, are classified as "available" or "unavailable". Available names are those published in accordance with

1416-479: Is the low costs of finding a mate and reproducing since the males and females are always together. Also, participants in multi-male groups have better access to resources such as food and living quarters. However, a major cost to living in a multi-male group is the constant competition for mates, mainly among males but also among females. Most non-human primate communities are more or less closed to contact with members of other communities. Most often, they are tied to

1475-411: 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 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

1534-678: The Atlantic Ocean to the Caribbean islands. The monkeys subsequently escaped or were released and became naturalized. Today, they are found on the West Indian islands of Barbados , Saint Kitts , Nevis , Anguilla , and Saint Martin . A colony also exists in Broward County, Florida . The classification of the Chlorocebus monkeys is undergoing change. They were previously lumped together with

1593-621: The International Code of Zoological Nomenclature ; the earliest such name for any taxon (for example, a genus) should then be selected as the " valid " (i.e., current or accepted) name for the taxon in question. Consequently, there will be more available names than valid names at any point in time; which names are currently in use depending on the judgement of taxonomists in either combining taxa described under multiple names, or splitting taxa which may bring available names previously treated as synonyms back into use. "Unavailable" names in zoology comprise names that either were not published according to

1652-799: The International Plant Names Index for plants in general, and ferns through angiosperms, respectively, and Nomenclator Zoologicus and the Index to Organism Names for zoological names. Totals for both "all names" and estimates for "accepted names" as held in the Interim Register of Marine and Nonmarine Genera (IRMNG) are broken down further in the publication by Rees et al., 2020 cited above. The accepted names estimates are as follows, broken down by kingdom: The cited ranges of uncertainty arise because IRMNG lists "uncertain" names (not researched therein) in addition to known "accepted" names;

1711-404: The platypus belongs to the genus Ornithorhynchus although George Shaw named it Platypus in 1799 (these two names are thus synonyms ) . However, the name Platypus had already been given to a group of ambrosia beetles by Johann Friedrich Wilhelm Herbst in 1793. A name that means two different things is a homonym . Since beetles and platypuses are both members of the kingdom Animalia,

1770-469: The French botanist Joseph Pitton de Tournefort (1656–1708) is considered "the founder of the modern concept of genera". The scientific name (or the scientific epithet) of a genus is also called the generic name ; in modern style guides and science, it is always capitalised. It plays a fundamental role in binomial nomenclature , the system of naming organisms , where it is combined with the scientific name of

1829-442: The base for higher taxonomic ranks, such as the family name Canidae ("Canids") based on Canis . However, this does not typically ascend more than one or two levels: the order to which dogs and wolves belong is Carnivora ("Carnivores"). The numbers of either accepted, or all published genus names is not known precisely; Rees et al., 2020 estimate that approximately 310,000 accepted names (valid taxa) may exist, out of

1888-466: The closely related guenons , Chlorocebus species are not primarily forest dwellers. Rather, they are semi- arboreal and semi- terrestrial , spending most of the day on the ground feeding and then sleeping at night in the trees. However, they must drink each day and are dependent on water, so they are never far from rivers or lakes. Like most other Old World monkeys, they have cheek pouches for storing food. They are diurnal , and are particularly active in

1947-401: The early morning and in the later afternoon or early evening. Chlorocebus monkeys live in multiple male/multiple female groups, which can be as large as 76 individuals. The group hierarchy plays an important role: dominant males and females are given priority in the search for food, and are groomed by subordinate members of the group. They exhibit female philopatry , a social system whereby

2006-409: The female presents her vulva to the male. Since groups are made of several more females than males, each male mates with several females. Generally, the male will display a striking, light-blue scrotal pouch, most prevalent during the mating season. Males do not take part in raising the young, but other females of the group (the "aunties") share the burden. The dominance hierarchy also comes into play, as

2065-532: The females remain in the same home range where they were born, and males leave once sexually mature. These monkeys are territorial animals, and a group can occupy an area of approximately .06 to 1.78 km (0.023 to 0.687 sq mi). They use a wide variety of vocalizations. They can with warn off members of other groups from their territory, and they can also warn members of their own troop of dangers from predators, using different calls for different predators. Monkeys scream when they are disciplined by members of

2124-446: The form "author, year" in zoology, and "standard abbreviated author name" in botany. Thus in the examples above, the genus Canis would be cited in full as " Canis Linnaeus, 1758" (zoological usage), while Hibiscus , also first established by Linnaeus but in 1753, is simply " Hibiscus L." (botanical usage). Each genus should have a designated type , although in practice there is a backlog of older names without one. In zoology, this

2183-422: The generally lower paternal probability in multi-male groups. However, in other primate species living in multi-male groups, males have been observed to kill infants. The aggressors are typically extra-group males, recent immigrants, have recently been introduced or are conceived outside the group, mainly due to the fact that they could not possibly be related to the infants they kill. A male's age and rank influence

2242-727: The generic name (or its abbreviated form) still forms the leading portion of the scientific name, for example, Canis lupus lupus for the Eurasian wolf subspecies, or as a botanical example, Hibiscus arnottianus ssp. immaculatus . Also, as visible in the above examples, the Latinised portions of the scientific names of genera and their included species (and infraspecies, where applicable) are, by convention, written in italics . The scientific names of virus species are descriptive, not binomial in form, and may or may not incorporate an indication of their containing genus; for example,

2301-487: The genus is thought to be the dryas monkey ( C. dryas ), which was previously classified in Cercopithecus and may potentially warrant its own genus. The dorsal fur of Chlorocebus monkeys varies by species from pale yellow through grey-green brown to dark brown, while the lower portion and the hair ring around the face is a whitish yellow. The face, hands, and feet are hairless and black, although their abdominal skin

2360-729: The group's females and immatures. In multi-male groups, there is typically no single male that has full control over the reproductive share of females. Females in multi-male groups will mate multiple times with different top ranking males as well as lower ranking males and occasionally bachelor "lone wolf" males outside of the group. Most female primates do not have a particular breeding season but can be receptive all year around, however they will most likely not mate if they are already caring for an infant. Female-female conflicts over reproduction have been overlooked in contrast to male-male competition. Recently, reviews and studies found that while it may not affect mating competition, sexual activity

2419-432: The idea that a newly defined genus should fulfill these three criteria to be descriptively useful: Moreover, genera should be composed of phylogenetic units of the same kind as other (analogous) genera. The term "genus" comes from Latin genus , a noun form cognate with gignere ('to bear; to give birth to'). The Swedish taxonomist Carl Linnaeus popularized its use in his 1753 Species Plantarum , but

2478-628: The largest component, with 23,236 ± 5,379 accepted genus names, of which 20,845 ± 4,494 are angiosperms (superclass Angiospermae). By comparison, the 2018 annual edition of the Catalogue of Life (estimated >90% complete, for extant species in the main) contains currently 175,363 "accepted" genus names for 1,744,204 living and 59,284 extinct species, also including genus names only (no species) for some groups. The number of species in genera varies considerably among taxonomic groups. For instance, among (non-avian) reptiles , which have about 1180 genera,

2537-446: The last five years, this view has changed as a result of careful documentation of intimate male-infant affiliations in certain species, especially in the savanna-dwelling baboons species and barbary macaques. Male paternal care includes: protection from predators, protection from aggression by conspecifics, access to preferred foods, grooming, transport, and adoption. Among other macaques, chimpanzees, and vervet monkeys, male care of young

2596-456: The lizard genus Anolis has been suggested to be broken down into 8 or so different genera which would bring its ~400 species to smaller, more manageable subsets. Multi-male group Basic requirements of individual primates include obtaining food, avoiding predators, and reproducing. When these basic requirements are best pursued in the company of others, groups will form. Multi-male groups , also known as multi-male/multi-female , are

2655-611: The medium-sized arboreal African monkeys of the guenon genus, Cercopithecus , where they were classified as a single species, Cercopithecus aethiops .

2714-572: The monkeys are massively infected with simian immunodeficiency virus (SIV), related to the ancestor of human immunodeficiency virus (HIV), both of which are widespread throughout populations. Chlorocebus monkeys are a natural host of SIV and do not succumb to immunodeficiency upon infection; therefore they are an important model in AIDS studies to understand protective mechanisms against AIDS. The monkeys infected with SIV and humans infected with HIV differ in microbial responses to infection. Vero cells are

2773-403: The most (>300) have only 1 species, ~360 have between 2 and 4 species, 260 have 5–10 species, ~200 have 11–50 species, and only 27 genera have more than 50 species. However, some insect genera such as the bee genera Lasioglossum and Andrena have over 1000 species each. The largest flowering plant genus, Astragalus , contains over 3,000 species. Which species are assigned to a genus

2832-428: The name could not be used for both. Johann Friedrich Blumenbach published the replacement name Ornithorhynchus in 1800. However, a genus in one kingdom is allowed to bear a scientific name that is in use as a generic name (or the name of a taxon in another rank) in a kingdom that is governed by a different nomenclature code. Names with the same form but applying to different taxa are called "homonyms". Although this

2891-447: The occurrence of infanticide. The youngest and highest-ranking immigrant males are more likely to commit infanticide than their older and lower-ranking counterparts if putative fathers fail to protect infants. A benefit of living in multi-male groups is the collective protection that the group as a whole receives from outsiders as well as sufficient protection of infants against infanticide from other outside roaming males. Another benefit

2950-448: The offspring of the more dominant group members get preferential treatment. The gestation time is about 163–165 days, and births are typically of a single young. The births usually happen at the beginning of the rainy season, when sufficient food is available. The young are weaned at about six months of age and are fully mature in four to five years. The life expectancy of the green monkeys is 11–13 years in captivity, and about 10–12 years in

3009-526: The provisions of the ICZN Code, e.g., incorrect original or subsequent spellings, names published only in a thesis, and generic names published after 1930 with no type species indicated. According to "Glossary" section of the zoological Code, suppressed names (per published "Opinions" of the International Commission of Zoological Nomenclature) remain available but cannot be used as the valid name for

3068-497: The specific name particular to the wolf. A botanical example would be Hibiscus arnottianus , a particular species of the genus Hibiscus native to Hawaii. The specific name is written in lower-case and may be followed by subspecies names in zoology or a variety of infraspecific names in botany . When the generic name is already known from context, it may be shortened to its initial letter, for example, C. lupus in place of Canis lupus . Where species are further subdivided,

3127-412: The standard format for a species name comprises the generic name, indicating the genus to which the species belongs, followed by the specific epithet, which (within that genus) is unique to the species. For example, the gray wolf 's scientific name is Canis lupus , with Canis ( Latin for 'dog') being the generic name shared by the wolf's close relatives and lupus (Latin for 'wolf') being

3186-403: The taxon is termed a synonym ; some authors also include unavailable names in lists of synonyms as well as available names, such as misspellings, names previously published without fulfilling all of the requirements of the relevant nomenclatural code, and rejected or suppressed names. A particular genus name may have zero to many synonyms, the latter case generally if the genus has been known for

3245-589: The troop. Facial expressions and body posturing serve as additional communication tools. Their social interactions are highly complex. Where alliances can be formed for benefit, deception is sometimes used. Physical affection is important between family members. Chlorocebus monkeys are, along with chimpanzees and baboons , the most omnivorous of the primates. They will eat leaves, gum, seeds, nuts, grasses, fungi, fruit, berries, flowers, buds, shoots, invertebrates, bird eggs, birds, lizards, rodents, and other vertebrate prey. Their preferred foods are fruit and flowers,

3304-566: The values quoted are the mean of "accepted" names alone (all "uncertain" names treated as unaccepted) and "accepted + uncertain" names (all "uncertain" names treated as accepted), with the associated range of uncertainty indicating these two extremes. Within Animalia, the largest phylum is Arthropoda , with 151,697 ± 33,160 accepted genus names, of which 114,387 ± 27,654 are insects (class Insecta). Within Plantae, Tracheophyta (vascular plants) make up

3363-429: The virus species " Salmonid herpesvirus 1 ", " Salmonid herpesvirus 2 " and " Salmonid herpesvirus 3 " are all within the genus Salmonivirus ; however, the genus to which the species with the formal names " Everglades virus " and " Ross River virus " are assigned is Alphavirus . As with scientific names at other ranks, in all groups other than viruses, names of genera may be cited with their authorities, typically in

3422-759: The wild. In the Caribbean islands, interactions between humans and monkeys are sometimes problematic. On the island of Barbados , farmers complain about the monkeys damaging their crops, and many try to find ways to keep them at bay. On Halloween 2006, a monkey was suspected of causing an island-wide, eight-hour blackout . The monkey apparently climbed a light pole and tripped an 11,000- and 24,000-volt powerline. In some African countries, many monkeys are killed by power lines, dogs, predatory animals e.g. wild cats, vehicles, shooting, poisoning, and hunting for sport. Added to this, an increase in desertification , and loss of habitat due to agriculture and urbanisation has occurred. As
