Erythrocebus
''Erythrocebus'' is a genus of Old World monkey. All three species in this genus are found in Africa, and are known as patas monkeys. While previously considered a monotypic In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa.

Erythrocebus Patas
The common patas monkey (''Erythrocebus patas''), also known as the wadi monkey or 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. Phylo ...

Erythrocebus Baumstarki
The southern patas monkey (''Erythrocebus baumstarki'') is a critically endangered species of Old World monkey found only in Tanzania, and formerly in Kenya. It may be the most endangered primate in Africa known to still be extant, with only 100 to 200 known wild inviduals. Taxonomy This species was described in 1905, but later reclassified as a subspecies of the common patas monkey (''E. patas''). However, a 2017 review on variation and taxonomy in ''Erythrocebus'' supported reclassifying it as a distinct species based on its distinctive appearance and geographic separation from the other two species. This taxonomy was followed by the IUCN Red List and American Society of Mammalogists. Phylogenetic evidence has also affirmed ''E. baumstarki'' as being a distinct species. It is possible that due to its seemingly-relictual distribution at the fringe of the range of ''Erythrocebus'', ''E.'' ''baumstarki'' may represent an ancient lineage of ''Erythrocebus'' that has been largely ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Erythrocebus Poliophaeus
The Blue Nile patas monkey (''Erythrocebus poliophaeus'') or Heuglin's patas monkey is a species of Old World monkey found in Africa along the Blue Nile river valley in Ethiopia, Sudan, and potentially South Sudan. While first described in 1862, it was synonymized with the common patas monkey (''E. patas'') in 1927. A 2017 study reclassified it as a distinct species. Taxonomy The species was described in 1862 by Heinrich Gottlieb Ludwig Reichenbach. Reichenbach's description was based on a live specimen from Fazogli and a skin from the vicinity of the White Nile, both received by Theodor von Heuglin, with a captive adult in Cairo confirming the species as distinct to him. However, in the first widely adopted taxonomy for ''Erythrocebus'' by Schwartz (1927), all ''Erythrocebus'' monkeys were classified into three subspecies: ''patas'', ''pyrrhonotus'' and ''baumstarki,'' creating a monotypic genus. This led to the synonymization of ''E. poliophaeus'' with ''E. patas''. In 2017, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Old World Monkey
Old World monkey is the common English name for a family of primates known taxonomically as the Cercopithecidae (). Twenty-four genera and 138 species are recognized, making it the largest primate family. Old World monkey genera include baboons (genus '' Papio''), red colobus (genus '' Piliocolobus'') and macaques (genus '' Macaca''). Common names for other Old World monkeys include the talapoin, guenon, colobus, douc (douc langur, genus ''Pygathrix''), vervet, gelada, mangabey (a group of genera), langur, mandrill, surili (''Presbytis''), patas, and proboscis monkey. Phylogenetically, they are more closely related to apes than to New World monkeys. They diverged from a common ancestor of New World monkeys around 45 to 55 million years ago. The smallest Old World monkey is the talapoin, with a head and body 34–37 cm in length, and weighing between 0.7 and 1.3 kg. The largest is the male mandrill, around 70 cm in length, and weighing up to 50 kg. Old ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Édouard Louis Trouessart
Édouard Louis Trouessart (25 August 1842 – 30 June 1927) was a French zoologist born in Angers. He studied military medicine in Strasbourg, but was forced to leave school due to serious health problems. In 1864 he started work as ''préparateur de physique'' at the Faculty of Poitiers, and in the process, dedicated his time and energies to natural history. He also resumed his studies in medicine, earning a medical doctorate in 1870. During the Franco-Prussian War, he served in the French army. Later, he was employed at the hospital in Villevêque. From 1882 to 1884, he was director at the Museum of Angers, and in the meantime taught classes in natural history at the high school in Angers. In 1885 he relocated to Paris, where he worked with Alphonse Milne-Edwards (1835-1900). After the death of Emile Oustalet (1844-1905), he attained the chair of zoology (mammals and birds), a position he maintained until 1926.

Johann Christian Daniel Von Schreber
Johann Christian Daniel von Schreber (17 January 1739 in Weißensee, Thuringia – 10 December 1810 in Erlangen), often styled J.C.D. von Schreber, was a German naturalist. Career He was appointed professor of'' materia medica'' at the University of Erlangen in 1769. In 1774, he began writing a multivolume set of books entitled ''Die Säugethiere in Abbildungen nach der Natur mit Beschreibungen'', which focused on the mammals of the world. Many of the animals included were given a scientific name for the first time, following the binomial system of Carl Linnaeus. From 1791 until his death in 1810, he was the president of the German Academy of Sciences Leopoldina. He was elected a member of the Royal Swedish Academy of Sciences in 1787. In April 1795, he was elected a Fellow of the Royal Society Numerous honors were bestowed on him, including the office of an imperial count palatine. Schreber also wrote on entomology, notably ''Schreberi Novae Species Insectorvm''. His herbar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
