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] |
Titi Monkey
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 prehensi ...

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 ...

Endemic (ecology)
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or bec ...

Plecturocebus
''Plecturocebus'' is one of three genera of titi monkeys. Historically, these monkeys were monotypic taxon, monogeneric, being placed in a single genus: ''Callicebus'' Thomas, 1903. Owing to the great diversity found across titi monkey species, a new genus-level taxonomy was proposed in 2016 that recognises three genera within the subfamily Callicebinae; ''Plecturocebus'' Byrne et al., 2016 for the Amazonian and Chaco titis of the ''moloch'' and ''donacophilus'' groups; ''Cheracebus'' Byrne et al., 2016 for the species of the ''torquatus'' group (Widow titis); and ''Callicebus'' Thomas, 1903 ''sensu stricto'', for species of the Atlantic Forest ''personatus'' group. ''Plecturocebus'' is derived from the Latin forms of three Greek words: plektos, meaning twist or plait, oura, meaning tail, and kebos, meaning long-tailed monkey. All together, this refers to the behavior of many titi monkeys to intertwine their tails when they sit next to each other. Species There are 25 species in ...

Primates Of Brazil
Primates is an order (biology), order of mammals, which is further divided into the Strepsirrhini, strepsirrhines, which include lemurs, galagos, and Lorisidae, lorisids; and the Haplorhini, haplorhines, which include Tarsiiformes, tarsiers and simians (monkeys and apes). Primates arose 74–63 million years ago first from small terrestrial animal, terrestrial mammals, which adapted for life in tropical forests: many primate characteristics represent adaptations to the challenging environment among Canopy (biology), tree tops, including large brain sizes, binocular vision, color vision, Animal communication, vocalizations, shoulder girdles allowing a large degree of movement in the upper limbs, and opposable thumbs (in most but not all) that enable better grasping and dexterity. 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 ...

Mammals Described In 1908
A mammal () is a vertebrate animal of the Class (biology), 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 Evolution of mammalian auditory ossicles, middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors Genetic divergence, diverged in the Carboniferous Period over 300 million years ago. Around 6,640 Neontology#Extant taxon, extant species of mammals have been described and divided into 27 Order (biology), 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, Mole (animal), moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the Artiodactyl, even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including Felidae, ...
