A mouse is a small rodent. Characteristically, mice are known to have a pointed snout, small rounded ears, a body-length scaly tail, and a high breeding rate. The best known mouse species is the common house mouse. Mice are also popular as pets. In some places, certain kinds of field mice are locally common. They are known to invade homes for food and shelter.
The Muroidea are a large superfamily of rodents, including mice, rats, voles, hamsters, lemmings, gerbils, and many other relatives. Although the Muroidea originated in Eurasia, they occupy a vast variety of habitats on every continent except Antarctica. Some authorities have placed all members of this group into a single family, Muridae, due to difficulties in determining how the subfamilies are related to one another. Many of the families within the Muroidea superfamily have more variations between the families than between the different clades. A possible explanation for the variations in rodents is because of the location of these rodents; these changes could have been due to radiation or the overall environment they migrated to or originated in. The following taxonomy is based on recent well-supported molecular phylogenies.
Heteromyidae is a family of rodents consisting of kangaroo rats, kangaroo mice, pocket mice and spiny pocket mice. Most heteromyids live in complex burrows within the deserts and grasslands of western North America, though species within the genus Heteromys are also found in forests and their range extends down as far as northern South America. They feed mostly on seeds and other plant parts, which they carry in their fur-lined cheek pouches to their burrows.
Perognathinae is a subfamily of rodents consisting of two genera of pocket mice. Most species live in complex burrows within the deserts and grasslands of western North America, They feed mostly on seeds and other plant parts, which they carry in their fur-lined cheek pouches to their burrows.
The spiny pocket mouse is a species of rodent in the family Heteromyidae and order Rodentia. It is found in Baja California in Mexico and in Arizona, California and Nevada.
The Trinidad spiny pocket mouse is a species of rodent in the family Heteromyidae. It is found in Colombia, Trinidad and Tobago, and Venezuela.
Desmarest's spiny pocket mouse is a species of rodent in the family Heteromyidae. It is found in Colombia, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, and Panama.
Goldman's spiny pocket mouse is a species of rodent in the family Heteromyidae. It has been reported to be a subspecies of Heteromys desmarestianus. It is found in Guatemala and Mexico. Its natural habitat is subtropical or tropical moist lowland forests.
The mountain spiny pocket mouse is a species of rodent in the family Heteromyidae. It is endemic to Costa Rica. Its natural habitat is subtropical or tropical moist lowland forests.
The Panamanian spiny pocket mouse, also known as Peter's spiny pocket mouse, is a species of heteromyid rodent endemic to Panama. It is very closely related to Salvin's spiny pocket mouse, and has been placed in the same species group by some authors. It was formerly placed in the genus Liomys, which is now recognized to be paraphyletic and has been subsumed into Heteromys.
The Mexican spiny pocket mouse is a species of rodent in the family Heteromyidae. It is native to Mexico and Texas in the United States where it is found in dry, scrubby habitats. The IUCN has assessed it as being of "least concern". It was formerly placed in the genus Liomys, which is now recognized to be paraphyletic and has been subsumed into Heteromys.
The painted spiny pocket mouse is a species of rodent in the family Heteromyidae. It is found in Mexico and the northern tip of Guatemala. It was formerly placed in the genus Liomys, which is now recognized to be paraphyletic and has been subsumed into Heteromys.
Salvin's spiny pocket mouse is a small to medium-sized rodent in the family Heteromyidae. It was formerly placed in the genus Liomys, which is now recognized to be paraphyletic and has been subsumed into Heteromys.
The Jaliscan spiny pocket mouse is a species of heteromyid rodent endemic to Mexico. The specific name spectabilis means "striking", and refers to the animal's relatively bright coloration. It was formerly placed in the genus Liomys, which is now recognized to be paraphyletic and has been subsumed into Heteromys.
The Paraguaná spiny pocket mouse is a South American species of rodent in the family Heteromyidae. It is known from two localities at elevations above 200 m, Cerro Santa Ana and the Fila de Monte Cano, within the Paraguaná Peninsula in Venezuela. While this region consists mostly of arid shrublands, this pocket mouse is found in elevated areas that provide cloud forest or mesic habitat with evergreen and semideciduous vegetation, such as terrestrial bromeliads. It is more likely to be found near streams. The species is threatened by habitat degradation due to goat grazing and development.
The Ecuadoran spiny pocket mouse is a species of rodent in the family Heteromyidae. It is endemic to central western Ecuador, where it is found at elevations from sea level to 2000 m on the coastal plain and western slopes of the Andes. The species is nocturnal and lives in dry tropical evergreen forests of the southernmost extension of the Choco; it creates well-defined runways, and is often found near streams. It is threatened by deforestation and fragmentation of its remaining habitat.
James Lloyd Patton, is an American evolutionary biologist and mammalogist. He is emeritus professor of integrative biology and curator of mammals at the Museum of Vertebrate Zoology, UC Berkeley and has made extensive contributions to the systematics and biogeography of several vertebrate taxa, especially small mammals.
Heteromyinae is a subfamily of rodents in the family Heteromyidae, commonly known as spiny pocket mice. It contains a single extant genus, Heteromys, as well as the extinct genera Diprionomys and Metaliomys. Heteromys was recently enlarged by inclusion of the members of formerly recognized heteromyine genus Liomys, which was found to be paraphyletic.
The overlook spiny pocket mouse is a species of heteromyid rodent endemic to Venezuela.
The cloud-dwelling spiny pocket mouse is a species of rodent (Rodentia) that is endemic to the high elevations of Cordillera de Tilarán and Cordillera de Guanacaste within Costa Rica. It is contained within the Heteromys desmarestianus species complex.
