Colombian Black-handed Titi
The Colombian black-handed titi monkey (''Cheracebus medemi'') is a species of titi, a type of New World monkey, endemic to Colombia. It was originally described in the genus '' Callicebus'' in 1963. Description Colombian black-handed titis sare relatively small primates with a fluffy coat and a long, bushy tail. This is longer than the body and cannot be used as a prehensile tail. The fur is predominantly black, and in contrast to closely related species, so are the hands. The head is small and roundish, along the throat a white or yellow, collar-like marking extends to the ears. Distribution and habitat Colombian black-handed titis are restricted to southern Colombia. Their range is located in the departments of Caquetá and Putumayo. The habitat of this species is tropical rainforests Tropical rainforests are rainforests that occur in areas of tropical rainforest climate in which there is no dry season – all months have an average precipitation of at least ...

Philip Hershkovitz
Philip Hershkovitz (12 October 1909 – 15 February 1997) was an American mammalogy, mammalogist. Born in Pittsburgh, he attended the Universities of Pittsburgh and Michigan and lived in South America collecting mammals. In 1947, he was appointed a curator at the Field Museum of Natural History in Chicago and he continued to work there until his death. He has published much on the mammals of the Neotropics, particularly primates and rodents, and described almost 70 new species and subspecies of mammals. About a dozen species have been named after him. Life Early life Philip Hershkovitz was born 12 October 1909 in Pittsburgh to parents Aba and Bertha (Halpern) Hershkovitz. He was the second child and only son among four siblings. He reported that his father died when he was nine years old. After graduating from Schenley High School in 1927, he attended the University of Pittsburgh from 1929 to 1931, majoring in zoology, before transferring to the University of Michigan at Ann Arb ...

Titi
The titis, or titi monkeys, are New World monkeys of the subfamily Callicebinae, which contains three extant genera: ''Cheracebus'', ''Callicebus'', and ''Plecturocebus.'' This subfamily also contains the extinct genera ''Miocallicebus, Homunculus'', and ''Carlocebus''. Titi monkeys live in South America, from Colombia, Ecuador and Peru, east through Brazil, and south to Bolivia and northern Paraguay. Description Depending on species, titis have a head and body length of , and a tail, which is longer than the head and body, of . The different titi species vary substantially in coloring, but resemble each other in most other physical ways. They have long, soft fur, and it is usually reddish, brownish, grayish or blackish, and in most species the underside is lighter or more reddish than the upperside. Some species have contrasting blackish or whitish foreheads, while all members of the genus ''Cheracebus'' have a white half-collar. The tail is always furry and is not prehensile. ...

New World Monkey
New World monkeys are the five families of primates that are found in the tropical regions of Mexico, Central and South America: Callitrichidae, Cebidae, Aotidae, Pitheciidae, and Atelidae. The five families are ranked together as the Ceboidea (), the only extant superfamily in the parvorder Platyrrhini (). Platyrrhini is derived from the Greek for "broad nosed", and their noses are flatter than those of other simians, with sideways-facing nostrils. Monkeys in the family Atelidae, such as the spider monkey, are the only primates to have prehensile tails. New World monkeys' closest relatives are the other simians, the Catarrhini ("down-nosed"), comprising Old World monkeys and apes. New World monkeys descend from African simians that colonized South America, a line that split off about 40 million years ago. Evolutionary history About 40 million years ago, the Simiiformes infraorder split into the parvorders Platyrrhini (New World monkeys) and Catarrhini ( apes and Old Worl ...

Endemic (ecology)
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colombia
Colombia (, ; ), officially the Republic of Colombia, is a country in South America with insular regions in North America—near Nicaragua's Caribbean coast—as well as in the Pacific Ocean. The Colombian mainland is bordered by the Caribbean Sea to the north, Venezuela to the east and northeast, Brazil to the southeast, Ecuador and Peru to the south and southwest, the Pacific Ocean to the west, and Panama to the northwest. Colombia is divided into 32 departments and the Capital District of Bogotá, the country's largest city. It covers an area of 1,141,748 square kilometers (440,831 sq mi), and has a population of 52 million. Colombia's cultural heritage—including language, religion, cuisine, and art—reflects its history as a Spanish colony, fusing cultural elements brought by immigration from Europe and the Middle East, with those brought by enslaved Africans, as well as with those of the various Amerindian civilizations that predate colonization.

Callicebus
''Callicebus'' is a genus of monkeys known as titi monkeys. Historically, titis were monogeneric, comprising only the genus ''Callicebus'' Thomas, 1903. Owing to the great diversity found across titi monkey species, a new genus-level taxonomy was recently proposed that recognises three genera within the subfamily Callicebinae The titis, or titi monkeys, are New World monkeys of the subfamily Callicebinae, which contains three extant genera: ''Cheracebus'', ''Callicebus'', and ''Plecturocebus.'' This subfamily also contains the extinct genera '' Miocallicebus, Homuncu ...; '' Cheracebus'' Byrne et al., 2016 for the species of the ''torquatus'' group (Widow titis); '' Plecturocebus'' Byrne et al., 2016 for the Amazonian and Chaco titis of the ''moloch'' and ''donacophilus'' groups; and ''Callicebus'' Thomas, 1903 ''sensu stricto'', for species of the Atlantic Forest ''personatus'' group. In 2014, a previously unknown orange ''Callicebus'' was spotted in the Peruvian Amazon; it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Primate
Primates are a diverse order of mammals. They are divided into the strepsirrhines, which include the lemurs, galagos, and lorisids, and the haplorhines, which include the tarsiers and the simians ( monkeys and apes, the latter including humans). Primates arose 85–55 million years ago first from small terrestrial mammals, which adapted to living in the trees of tropical forests: many primate characteristics represent adaptations to life in this challenging environment, including large brains, visual acuity, color vision, a shoulder girdle allowing a large degree of movement in the shoulder joint, and dextrous hands. Primates range in size from Madame Berthe's mouse lemur, which weighs , to the eastern gorilla, weighing over . There are 376–524 species of living primates, depending on which classification is used. New primate species continue to be discovered: over 25 species were described in the 2000s, 36 in the 2010s, and three in the 2020s. Primates have ...

Prehensile Tail
A prehensile tail is the tail of an animal that has adapted to grasp or hold objects. Fully prehensile tails can be used to hold and manipulate objects, and in particular to aid arboreal creatures in finding and eating food in the trees. If the tail cannot be used for this it is considered only partially prehensile - such tails are often used to anchor an animal's body to dangle from a branch, or as an aid for climbing. The term ''prehensile'' means "able to grasp" (from the Latin ''prehendere'', to take hold of, to grasp). Evolution One point of interest is the distribution of animals with prehensile tails. The prehensile tail is predominantly a New World adaptation, especially among mammals. Many more animals in South America have prehensile tails than in Africa and Southeast Asia. It has been argued that animals with prehensile tails are more common in South America because the forest there is denser than in Africa or Southeast Asia. In contrast, less dense forests such as in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Putumayo Department
Putumayo () is a department of Southern Colombia. It is in the south-west of the country, bordering Ecuador and Peru. Its capital is Mocoa. The word ''putumayo'' comes from the Quechua languages. The verb ''p'utuy'' means "to spring forth" or "to burst out", and ''mayu'' means river. Thus it means "gushing river". History Originally, the southwestern area of the department belonged to the Cofán Indians, the northwestern to the Kamentxá Indians, the central and southern areas to tribes that spoke Tukano languages (such as the Siona), and the eastern to tribes that spoke Witoto languages. Part of the Kamentxá territory was conquered by the Inca Huayna Cápac in 1492, who, after crossing the Cofán territory, established a Quechua population on the valley of Sibundoy, known today as Ingas. After the Inca defeat in 1533, the region was invaded by the Spanish in 1542, and from 1547 was administered by Catholic missions. The current territory of Putumayo was linked to P ...

Tropical Rainforest
Tropical rainforests are rainforests that occur in areas of tropical rainforest climate in which there is no dry season – all months have an average precipitation of at least 60 mm – and may also be referred to as ''lowland equatorial evergreen rainforest''. True rainforests are typically found between 10 degrees north and south of the equator (see map); they are a sub-set of the tropical forest biome that occurs roughly within the 28-degree latitudes (in the equatorial zone between the Tropic of Cancer and Tropic of Capricorn). Within the World Wildlife Fund's biome classification, tropical rainforests are a type of tropical moist broadleaf forest (or tropical wet forest) that also includes the more extensive seasonal tropical forests. Overview Tropical rainforests are characterized by two words: hot and wet. Mean monthly temperatures exceed during all months of the year. Average annual rainfall is no less than and can exceed although it typically ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monogamous Pairing In Animals
Monogamous pairing in animals refers to the natural history of mating systems in which species pair bond to raise offspring. This is associated, usually implicitly, with sexual monogamy. Monogamous mating Monogamy is defined as a pair bond between two adult animals of the same species – typically of the opposite sex. This pair may cohabitate in an area or territory for some duration of time, and in some cases may copulate and reproduce with only each other. Monogamy may either be short-term, lasting one to a few seasons or long-term, lasting many seasons and in extreme cases, life-long. Monogamy can be partitioned into two categories, social monogamy and genetic monogamy which may occur together in some combination, or completely independently of one another.Ophir, Alexander G., Phelps, Steven M., Sorin, Anna Bess & O. Wolff, J. (2008)Social but not genetic monogamy is associated with greater breeding success in prairie voles/ref> As an example, in the cichlid species ''Variabil ...
