Nelsonia is a genus of rodent in the family Cricetidae, found in Mexico. It contains the following species:
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, white-footed mice, packrats, and grasshopper mice.
The Mexican woodrat is a medium-sized pack rat.
Allen's woodrat is a species of rodent in the family Cricetidae. It is the only species in the genus Hodomys.
Goldman's diminutive woodrat is a species of rodent in the family Cricetidae. It is found only in Mexico.
The diminutive woodrat is a species of rodent in the family Cricetidae. It is endemic to Mexico.
The Tamaulipan woodrat is a species of rodent in the family Cricetidae. It is found only in Mexico.
Anthony's woodrat is an extinct subspecies of Bryant's woodrat in the family Cricetidae. It was found only on Isla Todos Santos in Baja California, Mexico. It is thought to have been driven to extinction through predation from feral cats.
Bryant's woodrat is a species of new-world rodent in the family Cricetidae native to the Southwestern United States and Mexico.
The Nicaraguan woodrat is a species of rodent in the family Cricetidae found in Honduras and Nicaragua.
The bushy-tailed woodrat, or packrat is a species of rodent in the family Cricetidae found in Canada and the United States. Its natural habitats are boreal forests, temperate forests, dry savanna, temperate shrubland, and temperate grassland.
The Arizona woodrat is a species of rodent in the family Cricetidae. It is found in Mexico and United States.
The dusky-footed woodrat is a species of nocturnal rodent in the family Cricetidae. They are commonly called "packrats" or "trade rats" and build large, domed dens that can reach several feet in height. Coyotes and other predators will attempt to prey on these rodents by laying waste to the dens, but the sheer volume of material is usually dissuasive. Occasionally, dusky-footed woodrats will build satellite dens in trees. Although these animals are solitary, except in the mating season, dens are frequently found in clusters of up to several dozen, forming rough "communities". The mating system in this species appears to be variable, with promiscuity most generally at high population densities and monogamy at lower densities.
The San Martín Island woodrat is an extinct subspecies of Bryant's woodrat in the family Cricetidae.
The Southern Plains woodrat is a species of rodent in the family Cricetidae. It is found in northwest Mexico and in Colorado, Kansas, New Mexico, Oklahoma, and Texas in the United States. The subspecies Neotoma micropus leucophaea, the White Sands woodrat, has white coloration, and is found only at White Sands National Park in New Mexico.
The Bolaños woodrat is a species of rodent in the family Cricetidae found only in Mexico.
The Sonoran woodrat is a species of rodent in the family Cricetidae found only in Mexico.
Neotoma leucodon is a species of rodent in the family Cricetidae. Although originally named from San Luis Potosí, Mexico, as a species by Merriam, the white-toothed woodrat was long considered to be a synonym of the white-throated woodrat. Molecular data, however, indicate the populations east of the Rio Grande in New Mexico and Trans-Pecos Texas represent a different species than morphologically similar populations west of the river.
The big-eared woodrat is a nocturnal rodent of the woodrat genus Neotoma, in the family Cricetidae. Closely related to, and formerly included in the species Neotoma fuscipes, it is endemic to western North America and occurs west and south of the Salinas Valley from the California Coast Ranges south of Monterey Bay to northern Baja California, as well as in the Sierra Nevada, extending north to the South Fork American River.
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.
