Dactylomys Dactylinus
''For Asian bamboo rats (family: Spalacidae), see Bamboo rat.'' The Amazon bamboo rat (''Dactylomys dactylinus'') is a species of spiny rat from the Amazon Basin of South America.Pearson, David L., and Les Beletsky. Travellers' Wildlife Guides: Peru. Northampton: Interlink. (2008) It is also referred to as coro-coro, Toró, Rato-do-Bambú, or Rata del Bambú in different parts of its range. The bamboo rat prefers to reside in areas of dense vegetation, such as clumps of bamboo or in the canopy. It is an arboreal browser, consuming primarily leaves and spending much of its time off the ground. Because the Amazon bamboo rat spends most of its time in heavily forested areas, it is difficult to observe, and not much is known about its habits. Physical characteristics The Amazon bamboo rat has a body length of over from the nose to the tip of the tail, and weighs approximately . The rat has a stout appearance, olive-grey fur streaked with black, and a tail with short, fine hairs. It ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dactylomys Boliviensis
__NOTOC__ The Bolivian bamboo rat (''Dactylomys boliviensis''), is a species of spiny rat from South America. Description The Bolivian bamboo rat is one of the largest species of spiny rat, with an adult head-body length of about and a tail long. It is also unusual in having a hairless tail, soft (rather than spiny) fur, and only four visible toes on the fore-feet. Most of the body is covered in soft grizzled greyish hair, and marked with blackish streaks. A darker line runs down the centre of the back, while the underparts have only sparse, white fur. The long tail is hairless, except at the base, and covered with large, pentagonal scales. The fifth toe on the forefeet is vestigial, consisting only of a tiny claw located on a tubercle at the side of the foot. The third and fourth toes are widely separated, giving the rat a grasp that has been likened to that of primates. The head has a distinctive blunt nose, and long whiskers. There is also a strong-smelling scent gland just ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Echimyini
Echimyini is a tribe of echimyid rodents, proposed in 2016, and containing 13 extant genera: all of the tree rats '' Echimys'', '' Phyllomys'', '' Makalata'', ''Pattonomys'', '' Toromys'', '' Diplomys'', '' Santamartamys'', and '' Isothrix'', the long recognized dactylomines '' Dactylomys'', '' Olallamys'', and '' Kannabateomys'', and the enigmatic and previously classified as eumysopines '' Lonchothrix'' and '' Mesomys''. All these spiny rats genera are arboreal. Worth of note, the arboreal genus '' Callistomys'' – the painted-tree rat – does not belong to the tribe Echimyini. Because it is phylogenetically closer to '' Myocastor'', '' Hoplomys'', ''Proechimys'', and '' Thrichomys'' than to the above-mentioned Echimyini genera, it is classified in the tribe Myocastorini. Phylogeny Five assemblages can be distinguished in the genus-level cladogram of Echimyini: * ''Echimys'' is closely related to ''Phyllomys'', ''Makalata'', ''Pattonomys'' and ''Toromys''. This clade is in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Echimyidae
Echimyidae is the family of neotropical spiny rats and their fossil relatives. This is the most species-rich family of hystricognath rodents. It is probably also the most ecologically diverse, with members ranging from fully arboreal to terrestrial to fossorial to semiaquatic habits. They presently exist mainly in South America; three members of the family also range into Central America, and the hutias are found in the Greater Antilles in the Caribbean. Species of the extinct subfamily Heteropsomyinae formerly lived on Cuba, Hispaniola, and Puerto Rico in the Antilles, probably until the arrival of Europeans. Characteristics In general form, most spiny rats resemble rats, although they are more closely related to guinea pigs and chinchillas. Most species have stiff, pointed hairs, or spines, that presumably serve for protection from predators. Many echimyids can break off their tails when attacked. This action may confuse predators long enough for the spiny rat to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isidore Geoffroy Saint-Hilaire
Isidore Geoffroy Saint-Hilaire (16 December 1805 – 10 November 1861) was a French zoology, zoologist and an authority on deviation from normal structure. In 1854 he coined the term ''éthologie'' (ethology). Biography He was born in Paris, the son of Étienne Geoffroy Saint-Hilaire. In his earlier years he showed an aptitude for mathematics, but eventually he devoted himself to the study of natural history and of medicine, and in 1824 he was appointed assistant naturalist to his father. In 1829 he delivered for his father the second part of a course of lectures on ornithology, and during the following three years he taught zoology at the ''Athénée'', and teratology at the ''École pratique''. He was elected a member of the French Academy of Sciences in 1833, was in 1837 appointed to act as deputy for his father at the faculty of sciences in Paris. During the following year he was sent to Bordeaux to organize a similar faculty there. He became successively; inspector of t ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus '' Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should cl ...

South America
South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere at the northern tip of the continent. It can also be described as the southern subregion of a single continent called America. South America is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean; North America and the Caribbean Sea lie to the northwest. The continent generally includes twelve sovereign states: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela; two dependent territories: the Falkland Islands and South Georgia and the South Sandwich Islands; and one internal territory: French Guiana. In addition, the ABC islands of the Kingdom of the Netherlands, Ascension Island (dependency of Saint Helena, Ascension and Tristan da Cunha, a British Overseas Territory), Bouvet Island ( dependency ...

Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
