Mura's Saddleback Tamarin
Mura's saddleback tamarin (''Leontocebus fuscicollis mura'') is a subspecies of monkey that was first seen by scientists in 2007 in the Brazilian state of Amazonas. The monkey, which is mostly gray and brown, weighs , is tall, and has a tail. According to the discoverers of this new subspecies, Mura's saddleback tamarin is threatened by several planned development projects in the region, including a proposed gas pipeline, two hydroelectric dams currently in the beginning stages of construction, and, most notably, a major highway cutting through the Amazon that is currently being paved. Conservationists fear the highway could fuel wider deforestation in the Amazon over the next two decades.

Monkey
Monkey is a common name that may refer to most mammals of the infraorder Simiiformes, also known as the simians. Traditionally, all animals in the group now known as simians are counted as monkeys except the apes, which constitutes an incomplete paraphyletic grouping; however, in the broader sense based on cladistics, apes (Hominoidea) are also included, making the terms ''monkeys'' and ''simians'' synonyms in regards to their scope. In 1812, Geoffroy grouped the apes and the Cercopithecidae group of monkeys together and established the name Catarrhini, "Old World monkeys", ("''singes de l'Ancien Monde''" in French). The extant sister of the Catarrhini in the monkey ("singes") group is the Platyrrhini (New World monkeys). Some nine million years before the divergence between the Cercopithecidae and the apes, the Platyrrhini emerged within "monkeys" by migration to South America likely by ocean. Apes are thus deep in the tree of extant and extinct monkeys, and any of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amazonas (Brazilian State)
Amazonas () is a state of Brazil, located in the North Region in the northwestern corner of the country. It is the largest Brazilian state by area and the 9th largest country subdivision in the world, and the largest in South America, being greater than the areas of Uruguay, Paraguay, and Chile combined. Mostly located in the Southern Hemisphere, it is the third largest country subdivision in the Southern Hemisphere after the Australian states of Western Australia and Queensland. Entirely in the Western Hemisphere, it is the fourth largest in the Western Hemisphere after Greenland, Nunavut and Alaska. It would be the sixteenth largest country in land area, slightly larger than Mongolia. Neighbouring states are (from the north clockwise) Roraima, Pará, Mato Grosso, Rondônia, and Acre. It also borders the nations of Peru, Colombia and Venezuela. This includes the Departments of Amazonas, Vaupés and Guainía in Colombia, as well as the Amazonas state in Venezuela, and ...

Tamarins
The tamarins are squirrel-sized New World monkeys from the family Callitrichidae in the genus ''Saguinus''. They are the first offshoot in the Callitrichidae tree, and therefore are the sister group of a clade formed by the lion tamarins, Goeldi's monkeys and marmosets. Taxonomy and evolutionary history Hershkovitz (1977) recognised ten species in the genus ''Saguinus'', further divided into 33 morphotypes based on facial pelage. A later classification into two clades was based on variations in dental measurements. A taxonomic review (Rylands et al., 2016) showed the tamarins are a sister group to all other callitrichids, branching off 15–13 million years ago. Within this clade, six species groups are historically recognised, ''nigricollis'', ''mystax'', ''midas'', ''inustus'', ''bicolor'' and ''oedipus'', five of which were shown to be valid with ''Sanguinus inustus'' placed within the ''midas'' group. The review noted that the smaller-bodied ''nigricollis'' group began div ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leontocebus
The saddle-back tamarins are squirrel-sized New World monkeys from the family Callitrichidae in the genus or subgenus ''Leontocebus''. They were split from the tamarin genus ''Saguinus'' based on genetic data and on the fact that saddle-back tamarins are sympatric with members of ''Saguinus'' to a greater extent than would be expected from two members of the same genus. However, this argument can be circular, as several other mammals show sympatry among congeneric species, such as armadillos (genus ''Dasypus''), spotted cats (genus ''Leopardus''), and fruit-eating bats (genus ''Artibeus''). Some authors still consider ''Leontocebus'' to be a subgenus of ''Saguinus''. Species include: *Cruz Lima's saddle-back tamarin, ('' Leontocebus cruzlimai'') * Brown-mantled tamarin or Spix's saddle-back tamarin, ('' Leontocebus fuscicollis'') *Lesson's saddle-back tamarin, ('' Leontocebus fuscus'') * Illiger's saddle-back tamarin, ('' Leontocebus illigeri'') *Red-mantled saddle-back tamarin ...

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Of Brazil
Brazil has the largest mammal diversity in the world, with more than 600 described species and more likely to be discovered. According to the International Union for Conservation of Nature, 66 of these species are endangered, and 40% of the threatened taxa belong to the primate group. 658 species are listed. The following tags are used to highlight each species' conservation status as assessed by the International Union for Conservation of Nature: Some species were assessed using an earlier set of criteria. Species assessed using this system have the following instead of near threatened and least concern categories: Infraclass: Metatheria Order: Didelphimorphia * Family: Caluromyidae ** Genus: '' Caluromys'' *** Brown-eared woolly opossum, ''C. lanatus'' LC *** Bare-tailed woolly opossum, ''C. philander'' LC * Family: Didelphidae ** Genus: ''Caluromysiops'' *** Black-shouldered opossum, ''Caluromysiops irrupta'' LC ** Genus: ''Glironia'' *** Bushy-tailed opossum, ' ...

Endemic Fauna Of Brazil
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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
