Neotominae
The Neotominae are a subfamily of the family Cricetidae. They consist of four tribes, 16 genera, and many species of New World rats and mice, predominantly found in North America. Among them are the well-known deer mice, packrats, and grasshopper mice. Neotomines are related to the other two subfamilies of mice in the New World, the Sigmodontinae and Tylomyinae. Many authorities place them all in a single subfamily, Sigmodontinae.

Peromyscus
''Peromyscus'' is a genus of rodents. They are commonly referred to as deer mice or deermice, not to be confused with the chevrotain or "mouse deer". They are New World mice only distantly related to the common house and laboratory mouse, ''Mus musculus''. From this distant relative, ''Peromyscus'' species are distinguished by relatively larger eyes, and also often two-tone coloring, with darker colors over the dorsum (back), and white abdominal and limb hair-coloring. In reference to the coloring, the word ''Peromyscus'' comes from Greek words meaning "booted mouse". They are also accomplished jumpers and runners by comparison to house mice, and their common name of "deer mouse" (coined in 1833) is in reference to both this agility as well as their two-toned coloring. The most common species of deer mice in the continental United States are two closely related species, '' P. maniculatus'' and '' P. leucopus''. In the United States, ''Peromyscus'' is the most populous mammali ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Neotoma
A pack rat or packrat, also called a woodrat or trade rat, are any species in the North and Central American rodent genus ''Neotoma''. Pack rats have a rat-like appearance, with long tails, large ears, and large, black eyes. Pack rats are noticeably larger than deer mice, harvest mice, and grasshopper mice, and are usually somewhat larger than cotton rats. Species ''Neotoma'' includes three subgenera, Daggers (†) mark extinct species: * Subgenus ''Neotoma'' ** '' Neotoma albigula'' - white-throated woodrat *** '' Neotoma albigula varia'' - Turner Island woodrat ** '' Neotoma angustapalata'' - Tamaulipan woodrat ** '' Neotoma bryanti'' - Bryant's woodrat *** '' Neotoma bryanti anthonyi'' - Anthony's woodrat *** †'' Neotoma bryanti bunkeri'' - Bunker's woodrat *** †'' Neotoma bryanti martinensis'' - San Martín Island woodrat ** '' Neotoma chrysomelas'' - Nicaraguan woodrat ** '' Neotoma devia'' - Arizona woodrat ** '' Neotoma ferruginea'' - Guatemala woodrat ** †'' ...

Ochrotomyini
The golden mouse (''Ochrotomys nuttalli'') is a species of New World mouse. It is usually 5–8 inches (12–25 cm) in body length, and has a soft pelage that ranges from golden-brownish to burnt orange in color. The genus name comes from the Greek words, ''ochra'', meaning "ocher", a yellow or brown earth pigment; ''oto-'' (from ''ous''), meaning "ear"; and ''mys'', meaning "mouse". Geographic range The golden mouse lives and breeds in the southeastern United States, including southeastern Missouri to West Virginia and southern Virginia, south to eastern Texas, the Gulf Coast, and central Florida. The golden mouse is currently regarded as a species with a secure population that is not severely fragmented throughout its range. Habitat Golden mice live in thick woodlands, swampy areas, among vines, and within small trees and shrubs. These animals especially like to live where honeysuckle, greenbrier, and red cedar grow. Golden mice in the south-central region of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 over 870 species, it is either the largest or 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 ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New World Rats And Mice
The New World rats and mice are a group of related rodents found in North and South America. They are extremely diverse in appearance and ecology, ranging from the tiny '' Baiomys'' to the large '' Kunsia''. They represent one of the few examples of muroid rodents (along with the voles) in North America, and the only example of muroid rodents to have made it into South America. The New World rats and mice are often considered part of a single subfamily, Sigmodontinae, but the recent trend among muroid taxonomists is to recognize three separate subfamilies. This strategy better represents the extreme diversity of species numbers and ecological types. Some molecular phylogenetic studies have suggested that the New World rats and mice are not a monophyletic group, but this is yet to be confirmed. Their closest relatives are clearly the hamsters and voles. The New World rats and mice are divided into 3 subfamilies, 12 tribes, and 84 genera. Classification *Family Cricetida ...

A pack rat or packrat, also called a woodrat or trade rat, are any species in the North and Central American rodent genus ''Neotoma''. Pack rats have a rat-like appearance, with long tails, large ears, and large, black eyes.

Sigmodontinae
The rodent subfamily Sigmodontinae includes New World rats and mice, with at least 376 species. Many authorities include the Neotominae and Tylomyinae as part of a larger definition of Sigmodontinae. When those genera are included, the species count numbers at least 508. Their distribution includes much of the New World, but the genera are predominantly South American, such as brucies. They invaded South America from Central America as part of the Great American Interchange near the end of the Miocene, about 5 million years ago. Sigmodontines proceeded to diversify explosively in the formerly isolated continent. They inhabit many of the same ecological niches that the Murinae occupy in the Old World. The "Thomasomyini" from the Atlantic Forest of Brazil are generally thought to be not especially related to the "real" Thomasomyini from the northern Andes and the Amazon rainforest. The genera '' Wiedomys'' and '' Sigmodon'' are generally placed in their own tribe, and the "phyl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Northern Pygmy Mouse
The northern pygmy mouse (''Baiomys taylori'') is a species of rodent in the family Cricetidae. It is known as ''ratón-pigmeo norteño'' in the Spanish-speaking areas of its range. It is found in Mexico and the United States. It is the smallest rodent in North America. Taxonomy This species was originally described as a member of the genus '' Hesperomys''. Afterwards it would be placed in the genus ''Peromyscus'' and even the hamster genus ''Cricetus''. In 1907, the American naturalist Edgar Mearns elevated the subgenus ''Baiomys'' to genus-level and included this species in it alongside '' Baiomys musculus''. It is likely more recent than ''Baiomys musculus'' and '' Baiomys brunneus'', as it less closely resembles fossil members of this genus. There are seven subspecies: *''Baiomys taylori allex'' ( Osgood, 1904 - native to the lowlands of southernmost Nayarit, western Jalisco, Colima, and southwestern Michoacán *''Baiomys taylori analogus'' (Osgood, 1917) - native to northe ...
