Dactylomys
''Dactylomys'' is the genus of South American bamboo rats They are arboreal members of the family Echimyidae. Systematics The genus name ''Dactylomys'' derives from the two Ancient Greek words (), meaning "finger", and (), meaning "mouse, rat", and refers to the middle two digits especially elongated relative to lateral ones as observed in these rodents. The genus contains three species: * '' Dactylomys boliviensis'' (Bolivian bamboo rat) * ''Dactylomys dactylinus'' (Amazon bamboo rat) * '' Dactylomys peruanus'' (Montane bamboo rat) Phylogeny ''Dactylomys'' is a member of the Echimyini clade of arboreal Arboreal locomotion is the locomotion of animals in trees. In habitats in which trees are present, animals have evolved to move in them. Some animals may scale trees only occasionally (scansorial), but others are exclusively arboreal. The hab ... Echimyidae rodents. The closest relative of ''Dactylomys'' is ''Olallamys'', and then ''Kannabateomys''. These South American ...

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. I ... [...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, particularly the southwest Amazon basin. A large, olivaceous rodent, it is nocturnal and feeds almost exclusively on bamboo. 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 ... [...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 West Indies in the Caribbean. Species of the extinct subfamily Heteropsomyinae formerly lived on Cuba, Hispaniola, and Puerto Rico in the Antilles. 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 Spine (zoology), spines, that presumably serve for protection from predators. Many echimyids can Autotomy, break off their tails when attacked. This action may confuse predators long enough for the spiny rat to escape. Unlike the tai ... [...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] |
Isidore Geoffroy Saint-Hilaire
Isidore Geoffroy Saint-Hilaire (; 16 December 1805 – 10 November 1861) was a French 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 the ac ...

Anselme Gaëtan Desmarest
Anselme Gaëtan Desmarest (6 March 1784 – 4 June 1838) was a French Zoology, zoologist and author. He was the son of Nicolas Desmarest and the father of Eugène Anselme Sébastien Léon Desmarest. Career Desmarest was a disciple of Georges Cuvier and Alexandre Brongniart, and in 1815, he succeeded Pierre André Latreille to the professorship of zoology at the '. He was elected to the American Philosophical Society in 1819 and to the Académie Nationale de Médecine in 1820. Publications Desmarest published ' (1805), ' (1825), ' (1820), and ' (1816–30, with André Marie Constant Duméril). His ''Mammalogie'' was significant as it contained a comprehensive list of all mammals known at the time, including living forms and extinct forms known only from fossils. Desmarest was one of the first scientists to routinely apply both genus and species names to animals. Prior to his time, it was common practice to give only a genus name to a new animal.

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] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. 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 taxonomy (biology), 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. Phylogeneti ...
