Acrobatic Cavy
The acrobatic cavy (''Kerodon acrobata'') also known as the Acrobatic Moco and Climbing Cavy is a cavy species native to Brazil in the Amazon rainforest. It is found from Goiás state to Tocantins state, west of the Espigão Mestre, Serra Geral de Goiás, and is also found in Terra Ronca State Park. Diet They are herbivores known to eat a generalized diet of leaves, flowers, bud, bark and fruit from 16 different types of native plantations. Habitat Found in seasonally dry areas of the Amazon rainforest , often in limestone outcrops and emerge to forage and climb trees. Appearance Acrobatic Cavies are a large rodent averaging 1 kg in weight, their fur ranges from dark grey to light brown with orange-brown feet, mostly observed on hindfeet. Their tails are vestigial. Phylogeny The Acrobatic Cavy belongs to the order Rodentia, in the family Caviidae (Guinea-pig like rodents) which has two subfamilies (formerly three) with Acrobatic Cavies being in a new subfamily Hy ...

João Moojen
João Moojen de Oliveira (December 1, 1904 in Leopoldina, MG, Brazil – March 31, 1985 in Rio de Janeiro, RJ, Brazil) was a zoologist dedicated to the systematics of Brazilian mammals, particularly rodents and primates. He was also interested in birds. He collected extensively between the 1930s and 50s and wrote "Os Roedores do Brasil" in 1952, a key book on Brazilian rodents. He was an authority on spiny rats of the genus ''Phyllomys''. As well as performing research, Moojen worked significantly as a teacher and technical advisor; positions held include: head of the Biology Department of Escola Superior de Agricultura e Veterinária do Estado de Minas Gerais, in Viçosa; Professor-Head of Natural History of Colégio Universitário da Universidade do Brasil; Naturalist of Vertebrate and Invertebrate Zoology Division of Museu Nacional including headed this division into two stages and collected most of the mammals deposited in this collection and in Universidade do Estado do Rio de ...

Vestigiality
Vestigiality is the retention, during the process of evolution, of genetically determined structures or attributes that have lost some or all of the ancestral function in a given species. Assessment of the vestigiality must generally rely on comparison with homologous features in related species. The emergence of vestigiality occurs by normal evolutionary processes, typically by loss of function of a feature that is no longer subject to positive selection pressures when it loses its value in a changing environment. The feature may be selected against more urgently when its function becomes definitively harmful, but if the lack of the feature provides no advantage, and its presence provides no disadvantage, the feature may not be phased out by natural selection and persist across species. Examples of vestigial structures (also called degenerate, atrophied, or rudimentary organs) are the loss of functional wings in island-dwelling birds; the human vomeronasal organ; and the hi ...

Cavies
Caviidae, the cavy family, is composed of rodents native to South America and includes the domestic guinea pig, wild cavies, and the largest living rodent, the capybara. They are found across South America in open areas from moist savanna to thorn forests or scrub desert. This family of rodents has fewer members than most other rodent families, with 19 species in 6 genera in 3 subfamilies. Characteristics With the exception of the maras, which have a more rabbit-like appearance, caviids have short, heavy bodies and large heads. Most have no visible tails. They range in size from the smaller cavies at 22 cm in body length, and 300 grams in weight, up to the capybara, the largest of all rodents at 106 to 134 cm in length, and body weights of 35 to 66 kilograms. Even larger forms existed in the Pliocene, such as '' Phugatherium'', which was about the size of a tapir. They are herbivores, eating tough grasses or softer leaves, depending on species.

ISSN (identifier)
An International Standard Serial Number (ISSN) is an eight-digit serial number used to uniquely identify a serial publication, such as a magazine. The ISSN is especially helpful in distinguishing between serials with the same title. ISSNs are used in ordering, cataloging, interlibrary loans, and other practices in connection with serial literature. The ISSN system was first drafted as an International Organization for Standardization (ISO) international standard in 1971 and published as ISO 3297 in 1975. ISO subcommittee TC 46/SC 9 is responsible for maintaining the standard. When a serial with the same content is published in more than one media type, a different ISSN is assigned to each media type. For example, many serials are published both in print and electronic media. The ISSN system refers to these types as print ISSN (p-ISSN) and electronic ISSN (e-ISSN). Consequently, as defined in ISO 3297:2007, every serial in the ISSN system is also assigned a linking ISSN (ISS ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Doi (identifier)
A digital object identifier (DOI) is a persistent identifier or handle used to uniquely identify various objects, standardized by the International Organization for Standardization (ISO). DOIs are an implementation of the Handle System; they also fit within the URI system (Uniform Resource Identifier). They are widely used to identify academic, professional, and government information, such as journal articles, research reports, data sets, and official publications. DOIs have also been used to identify other types of information resources, such as commercial videos. A DOI aims to resolve to its target, the information object to which the DOI refers. This is achieved by binding the DOI to metadata about the object, such as a URL where the object is located. Thus, by being actionable and interoperable, a DOI differs from ISBNs or ISRCs which are identifiers only. The DOI system uses the indecs Content Model for representing metadata. The DOI for a document remains fixed over th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rock Cavy
The rock cavy or ''mocó'' (''Kerodon rupestris'') is a cavy species endemic to eastern Brazil which has also been introduced to the Atlantic island of Fernando de Noronha. The rock cavy is called ''mocó'' in Brazilian Portuguese, and ''koriko pexerumen'' in the Xukuru language of Pernambuco, Brazil. Description The rock cavy is a fairly large rodent weighing up to . Like other cavy species, their tails are vestigial or absent. Their backs are grey-brown and their bellies tan to light brown. In appearance and habit, they closely resemble the unrelated African rock hyraxes (an example of convergent evolution). They are herbivorous, feeding on seeds and leaves of the scrubby vegetation that grows in their territories. This vegetation consists of tender leaves and certain species of creeper. Distribution and habitat Rock cavies are found in dry, rocky areas with low, scrubby vegetation, and they prefer to reside close to stony mountainsides and hills. They are native to eas ...

Capybara
The capybaraAlso called capivara (in Brazil), capiguara (in Bolivia), chigüire, chigüiro, or fercho (in Colombia and Venezuela), carpincho (in Argentina, Paraguay and Uruguay) and ronsoco (in Peru). or greater capybara (''Hydrochoerus hydrochaeris'') is a giant cavy rodent native to South America. It is the largest living rodent and a member of the genus ''Hydrochoerus''. The only other extant member is the lesser capybara (''Hydrochoerus isthmius''). Its close relatives include guinea pigs and rock cavies, and it is more distantly related to the agouti, the chinchilla, and the nutria. The capybara inhabits savannas and dense forests, and lives near bodies of water. It is a highly social species and can be found in groups as large as 100 individuals, but usually live in groups of 10–20 individuals. The capybara is hunted for its meat and hide and also for grease from its thick fatty skin. It is not considered a threatened species. Etymology Its common name is derived fro ...

Hydrochoerinae
Hydrochoerinae is a subfamily of Caviidae, consisting of two living genera, ''Hydrochoerus'', the capybaras, and ''Kerodon'', the rock cavies. In addition, a number of extinct genera related to capybaras should also be placed in this subfamily. The taxonomy of Hydrochoerinae is confused because, until 2005, living capybaras and their extinct relatives were placed in their own family, Hydrochoeridae.McKenna, Malcolm C., and Bell, Susan K. 1997. ''Classification of Mammals Above the Species Level.'' Columbia University Press, New York, 631 pp. Recent molecular phylogenetic studies recognize a close relationship between ''Hydrochoerus'' and ''Kerodon'', supporting placement of both genera in a subfamily of Caviidae. Paleontological classifications have yet to incorporate this new taxonomy, and continue to use Hydrochoeridae for all capybaras, while using Hydrochoerinae for the living genus and its closest fossil relatives such as ''Neochoerus ''Neochoerus'' ("new hog") is an ...

Terra Ronca State Park
The Terra Ronca State Park was created by decree nr. 10,879 of 7 July 1989 and had its area and boundaries established by decree nr. 4,700 of 21 August 1996, covering the municipality of São Domingos. Around the state park they created the environmental protection area (APA) of the Serra Geral, by decree nr. 4,666 of 16 April 1996. The areas of these two protected areas are of restricted use and regularly monitored and audited by the Agência Goiana de Meio Ambiente e Recursos Naturais, covering respectively 57,018 ha and 40,000 ha. It is one of the most beautiful and significant geo-morfologic sets of Brazil. The implementation of the park and the APA has as their main focus the protection of all the natural complex of the region composed of numerous caves with a rich system of speleothems, springs and rivers of clear waters that run inside and outside the caves, as well the diverse flora and fauna of the region, offering a spectacle for the vastness of countless species, inclu ...

Kerodon
The genus ''Kerodon'' (vernacular name Mocos; Rock Cavies) contains two species of South American rock cavies, related to capybaras and guinea pigs. They are found in semiarid regions of northeast Brazil known as the Caatinga. This area has a rocky terrain with large granite boulders that contain rifts and hollows where ''Kerodon'' spp. primarily live. Characteristics They are hystricomorph rodents, medium-sized, with rabbit-like bodies, a squirrel-like face, and heavily padded feet. Their nails are blunt on all digits except a small grooming claw on the outermost digit of the foot. Fully grown adults weigh around 1000 g or 31-35 oz, and range in length from 200 to 400 mm or 7.5 to 16 in. They forage for mostly leaves, grasses, seeds, and tree bark. They breed year round, usually having one to three litters per year and one to three young per pregnancy. Gestation last around 76 days and the young are weaned from the mother within 33 days. They reach sexual maturity at 133 days. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Serra Geral
The Serra Geral (General Mountains) is a mountain range in southern Brazil, constituting the southern portion of the Serra do Mar system which runs along Brazil's southeastern coast. The Serra Geral runs parallel to the Atlantic coast in Santa Catarina and northern Rio Grande do Sul states, separating a narrow coastal plain from an interior plateau. The coastal plain is characterized by short rivers and frequent lagoons and bays, and lies within the humid tropical Serra do Mar coastal forests ecoregion. The plateau to the west of the range is drained by tributaries of the Uruguay River, including the Pelotas and Canoas, and by the Jacuí River and its tributaries, which drains south into the Lagoa dos Patos of Rio Grande do Sul. The Serra Geral is home to Aparados da Serra National Park and Serra Geral National Park, which are notable for their enormous canyons. The plateau is the coldest part of Brazil, with frequent frosts and yearly snow, being home to the montane ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
