Joel Asaph Allen
Joel Asaph Allen (July 19, 1838 – August 29, 1921) was an American zoology, zoologist, mammalogy, mammalogist, and ornithology, ornithologist. He became the first president of the American Ornithologists' Union, the first curator of birds and mammals at the American Museum of Natural History, and the first head of that museum's Department of Ornithology. He is remembered for Allen's rule, which states that the bodies of endotherms (warm-blooded animals) vary in shape with climate, having increased surface area in hot climates to lose heat, and minimized surface area in cold climates, to conserve heat. Early life Allen was born in Springfield, Massachusetts, the son of Joel Allen and Harriet Trumbull. He studied and collected specimen of natural history early in life, but he was forced to sell his relatively large collection so that he could attend the Wilbraham & Monson Academy in 1861. The following year, he transferred to Harvard University, where he studied under Louis Agassi ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Rodent
Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for New Zealand, Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/richochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and pikas, whose i ...

Nephelomys
''Nephelomys'' is a genus of South American oryzomyine rodents found in the Andes from Bolivia to Venezuela, with a westward extension into the mountains of Costa Rica. Its generic name is derived from the Ancient Greek word ''nephelê'' "mist", referring to the cloud forest habitat of the members of the genus. The species in this genus have historically been placed in ''Oryzomys'', but in 2006, Brazilian zoologist Marcelo Weksler and coworkers described it as a separate genus, because it is not closely related to the type species of ''Oryzomys''.Weksler, 2006 They are most closely related to other members of clade B, including ''Euryoryzomys'', ''Transandinomys'', '' Hylaeamys'', '' Oecomys'', and ''Handleyomys'', with some weak evidence supporting a sister-group relationship to ''Transandinomys''.Weksler et al., 2006, p. 20 ''Oryzomys'' appears in a different part of the oryzomyine evolutionary radiation, perhaps close to ''Holochilus'' and related genera.

Cricetidae
The Cricetidae are a family of rodents in the large and complex superfamily Muroidea. It includes true hamsters, voles, lemmings, muskrats, and New World rats and mice. At almost 608 species, it is the second-largest family of mammals, and has members throughout the Americas, Europe and Asia. Characteristics The cricetids are small mammals, ranging from just in length and in weight in the New World pygmy mouse up to and in the muskrat. The length of their tails varies greatly in relation to their bodies, and they may be either furred or sparsely haired. The fur of most species is brownish in colour, often with a white underbelly, but many other patterns exist, especially in the cricetine and arvicoline subfamilies. Like the Old World mice, cricetids are adapted to a wide range of habitats, from the high Arctic to tropical rainforests and hot deserts. Some are arboreal, with long balancing tails and other adaptations for climbing, while others are semiaquatic, with w ...

Type Locality (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost a ...

Colombia
Colombia (, ; ), officially the Republic of Colombia, is a country in South America with insular regions in North America—near Nicaragua's Caribbean coast—as well as in the Pacific Ocean. The Colombian mainland is bordered by the Caribbean Sea to the north, Venezuela to the east and northeast, Brazil to the southeast, Ecuador and Peru to the south and southwest, the Pacific Ocean to the west, and Panama to the northwest.

Oryzomys
''Oryzomys'' is a genus of semiaquatic rodents in the tribe Oryzomyini living in southern North America and far northern South America. It includes eight species, two of which—the marsh rice rat (''O. palustris'') of the United States and '' O. couesi'' of Mexico and Central America—are widespread; the six others have more restricted distributions. The species have had eventful taxonomic histories, and most species were at one time included in the marsh rice rat; additional species may be recognized in the future. The name ''Oryzomys'' was established in 1857 by Spencer Fullerton Baird for the marsh rice rat and was soon applied to over a hundred species of American rodents. Subsequently, the genus gradually became more narrowly defined until its current contents were established in 2006, when ten new genera were established for species previously placed in ''Oryzomys''. Species of ''Oryzomys'' are medium-sized rats with long, coarse fur. The upperparts are gray ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Nephelomys Albigularis
''Nephelomys albigularis'', also known as the white-throated oryzomys or Tomes's rice rat, is a species of rodent in the genus '' Nephelomys'' of family Cricetidae. Described in 1860, it was the first ''Nephelomys'' species to be discovered. It was originally described in the defunct genus '' Hesperomys'' as ''Hesperomys albigularis'' and considered related to the much smaller ''H. longicaudatus'' (currently ''Oligoryzomys longicaudatus''). By 1894, it was placed in ''Oryzomys'', as ''Oryzomys albigularis'', and associated with what is now '' Nephelomys meridensis''. In the early 1960s, the scope of the species was considerably expanded to include most of the species that are now in ''Nephelomys'', as well as a single name, ''boliviae'', that is currently a synonym of '' Euryoryzomys nitidus''. From 1976 on, several of these were reinstated as separate species.Musser and Carleton, 2005, p. 1145 In 2006, a phylogenetic analysis by Marcelo Weksler of the oryzomyine tribe, in which ...

Nephelomys Maculiventer
''Nephelomys maculiventer'' is a species of rodent in the genus ''Nephelomys'' of family Cricetidae. The type locality is in Colombia, at "Sierra El Libano, alt. 6000 ft, Santa Marta District". It was originally described on the basis of 47 specimens, including 34 from Sierra El Libano and 13 from "Valparaiso". ''N. maculiventer'' has long and soft fur that is rufous in color on the upperparts and becomes lighter towards the sides. This coloration changes abruptly into that of the underparts, which are pure white in some adults. Juveniles are darker in color, with the underparts dark gray. As the animal matures, the gray fur of the underparts is gradually replaced by white fur. The ears are brown and nearly unhaired. The hindfeet are gray. The tail is brown above and lighter below. In 29 individuals of both sexes, the total length varies from , the tail length from , and the hindfoot length (including claws) from . On average, males are slightly larger than females.
