Schneider's Marmoset
Schneider's marmoset (''Mico schneideri'') is a species of marmoset of the genus ''Mico'' in the family Callitrichidae. Endemic to Brazil, it is found in the Amazon rainforest of Mato Grosso state. It is found on the interfluve between the Juruena and Teles Pires rivers. Schneider's marmoset is found in primary and secondary '' terra firma'' rainforests and in the transition zone to the Cerrado. Previously recognised as Emilia's marmoset (''Mico emiliae''), a morphological and phylogenetic study in 2021 showed the species is distinct and it was formally described as a new species. Schneider's marmoset has a lead-coloured saddle and rump with cream-silver underparts. There is grey fur on the back of its neck and on top of its head. Its hands are light orange, its feet are orange, and its tail is black. Schneider's marmoset is found in the "arc of deforestation", a 2,500 km stretch of the Amazon rainforest which is under greatest pressure from deforestation, mostly due to ag ...

Emilia's Marmoset
The Emilia's marmoset (''Mico emiliae''), also known as Snethlage's marmoset, is a marmoset endemic to Brazil.Emmons, L & Feer, F. (1997). ''Neotropical Rainforest Mammals''. It is found only in the Brazilian states of Pará and Mato Grosso. It was named to honour German-born Brazilian ornithologist Emilie Snethlage Maria Emilie Snethlage (April 13, 1868 – November 25, 1929) was a German-born Brazilian naturalist and ornithologist who worked on the bird fauna of the Amazon. Snethlage collected in Brazil from 1905 until her death. She was the director of t ....

Taxon
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's Linnaean taxonomy, system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard de Jussieu, Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first mad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canine Tooth
In mammalian oral anatomy, the canine teeth, also called cuspids, dog teeth, or (in the context of the upper jaw) fangs, eye teeth, vampire teeth, or vampire fangs, are the relatively long, pointed teeth. They can appear more flattened however, causing them to resemble incisors and leading them to be called ''incisiform''. They developed and are used primarily for firmly holding food in order to tear it apart, and occasionally as weapons. They are often the largest teeth in a mammal's mouth. Individuals of most species that develop them normally have four, two in the upper jaw and two in the lower, separated within each jaw by incisors; humans and dogs are examples. In most species, canines are the anterior-most teeth in the maxillary bone. The four canines in humans are the two maxillary canines and the two mandibular canines. Details There are generally four canine teeth: two in the upper (maxillary) and two in the lower (mandibular) arch. A canine is placed laterally to ...

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 World mon ...

Exudate
An exudate is a fluid emitted by an organism through pores or a wound, a process known as exuding or exudation. ''Exudate'' is derived from ''exude'' 'to ooze' from Latin ''exsūdāre'' 'to (ooze out) sweat' (''ex-'' 'out' and ''sūdāre'' 'to sweat'). Medicine An exudate is any fluid that filters from the circulatory system into lesions or areas of inflammation. It can be a pus-like or clear fluid. When an injury occurs, leaving skin exposed, it leaks out of the blood vessels and into nearby tissues. The fluid is composed of serum, fibrin, and leukocytes. Exudate may ooze from cuts or from areas of infection or inflammation. Types * Purulent or suppurative exudate consists of plasma with both active and dead neutrophils, fibrinogen, and necrotic parenchymal cells. This kind of exudate is consistent with more severe infections, and is commonly referred to as pus. * Fibrinous exudate is composed mainly of fibrinogen and fibrin. It is characteristic of rheumatic carditis, bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Incisor
Incisors (from Latin ''incidere'', "to cut") are the front teeth present in most mammals. They are located in the premaxilla above and on the mandible below. Humans have a total of eight (two on each side, top and bottom). Opossums have 18, whereas armadillos have none. Structure Adult humans normally have eight incisors, two of each type. The types of incisor are: * maxillary central incisor (upper jaw, closest to the center of the lips) * maxillary lateral incisor (upper jaw, beside the maxillary central incisor) * mandibular central incisor (lower jaw, closest to the center of the lips) * mandibular lateral incisor (lower jaw, beside the mandibular central incisor) Children with a full set of deciduous teeth (primary teeth) also have eight incisors, named the same way as in permanent teeth. Young children may have from zero to eight incisors depending on the stage of their tooth eruption and tooth development. Typically, the mandibular central incisors erupt first, followed ...

Sister Taxon
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxonomi ...

Black-tailed Marmoset
The black-tailed marmoset (''Mico melanurus'') is a species of New World monkey from central South America, where it ranges from the south-central Amazon in Brazil, south through the Pantanal and eastern Bolivia, to the Chaco in far northern Paraguay. It is the southernmost member of the genus ''Mico'' and the only species where most of its range is outside the Amazon.Rylands, Mittermeier, Coimbra-Filho, Heymann, de la Torre, Silva Jr., Kierulff, Noronha and Röhe (2008). ''Marmosets and Tamarins: Pocket Identification Guide.'' Conservation International. The black-tailed marmoset is dark brown with paler foreparts and a black tail. Unlike most of its relatives, it has a striking white or yellow-white stripe that extends down its thigh. Its ears are naked, flesh-colored and stand out from the fur. They reach a size of 18 to 28 cm and weigh from 300 to 400 g. Black-tailed marmosets are diurnal and arboreal, using their claws to climb trees. Originally rain forest inhabi ...

Paratype
In zoology and botany, a paratype is a specimen of an organism that helps define what the scientific name of a species and other taxon actually represents, but it is not the holotype (and in botany is also neither an isotype nor a syntype). Often there is more than one paratype. Paratypes are usually held in museum research collections. The exact meaning of the term ''paratype'' when it is used in zoology is not the same as the meaning when it is used in botany. In both cases however, this term is used in conjunction with ''holotype''. Zoology In zoological nomenclature, a paratype is officially defined as "Each specimen of a type series other than the holotype.", ''International Code of Zoological Nomenclature'' In turn, this definition relies on the definition of a "type series". A type series is the material (specimens of organisms) that was cited in the original publication of the new species or subspecies, and was not excluded from being type material by the author (th ...

Belém
Belém (; Portuguese for Bethlehem; initially called Nossa Senhora de Belém do Grão-Pará, in English Our Lady of Bethlehem of Great Pará) often called Belém of Pará, is a Brazilian city, capital and largest city of the state of Pará in the country's north. It is the gateway to the Amazon River with a busy port, airport, and bus/coach station. Belém lies approximately 100 km upriver from the Atlantic Ocean, on the Pará River, which is part of the greater Amazon River system, separated from the larger part of the Amazon delta by ''Ilha de Marajó'' ( Marajo Island). With an estimated population of 1,499,641 people — or 2,491,052, considering its metropolitan area — it is the 11th most populous city in Brazil, as well as the 16th by economic relevance. It is the second largest in the North Region, second only to Manaus, in the state of Amazonas. Founded in 1616 by the Kingdom of Portugal, Belém was the first European colony on the Amazon but did not become ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Museu Paraense Emílio Goeldi
The Museu Paraense Emílio Goeldi (MPEG) is a Brazilian research institution and museum located in the city of Belém, state of Pará, Brazil. It was founded in 1866 by Domingos Soares Ferreira Penna as the Pará Museum of Natural History and Ethnography, and was later named in honor of Swiss naturalist Émil August Goeldi, who reorganized the institution and was its director from 1894 to 1905. It is now the "main research center on natural systems and sociocultural processes of the Brazilian Amazon." The museum and zoological park are listed as protected sites by both the National Institute of Historic and Artistic Heritage (IPHAN) and the Department of Historic, Artistic and Cultural Heritage of the state of Pará. Activities The institution has the mission of researching, cataloging and analyzing the biological and sociocultural diversity of the Amazon Basin, contributing to its cultural memory and its regional development. It has also the aim of increasing public awarenes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
