Woodrat
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 ** †'' ...

Neotoma Albigula
The white-throated woodrat (''Neotoma albigula'') is a species of rodent in the family Cricetidae. It is found from central Mexico north to Utah and Colorado in the United States. It is primarily a western species in the United States, extending from central Texas west to southeastern California. Populations east of the Rio Grande in New Mexico and Trans-Pecos Texas, previously considered to be variants of the white-throated woodrat, have since 1988 been assigned to the white-toothed woodrat (''Neotoma leucodon''). The animal lives mostly in the Upper and Lower Sonoran life zones, occurring from pinyon-juniper woodland in higher country to desert habitats at lower elevations. As with other species of woodrats, the white-throated woodrat constructs middens of a variety of materials such as sticks, cactus parts, and miscellaneous debris. An above-ground chamber within the midden contains a nest lined with grasses and kept free of feces. In non-rocky areas, the den usually is sever ...

Neotoma Floridana
The eastern woodrat (''Neotoma floridana''), also known as the Florida woodrat or bush rat, is a pack rat native to the central and Eastern United States. It constructs large dens that may serve as nests for many generations and stores food in outlying caches for the winter. While widespread and not uncommon, it has declined or disappeared in several areas. Taxonomy Eight subspecies of the eastern woodrat are currently recognized: ''N. f. illinoensis'', ''N. f. floridana'' (the nominate), ''N. f. smalli'', ''N. f. baileyi'', ''N. f. pennsylvanica'', ''N. f. attwateri'', ''N. f. osagensis'', and ''N. f. rubida''. Of these, the Key Largo woodrat (''N. f. smalli'') is classified as endangered by the IUCN. The Allegheny woodrat (''Neotoma magister'') was previously considered a subspecies but was elevated to species status based on comparative mitochondrial DNA analyses. Subspecies are thought to be descended from one species living along the Appalachian Plateau, which subsequentl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Neotoma Magister
The Allegheny woodrat (''Neotoma magister''), is a species of "pack rat" in the genus ''Neotoma''. Once believed to be a subspecies of the eastern woodrat (''Neotoma floridana''), extensive DNA analysis has proven it to be a distinct species. Description The Allegheny woodrat is a medium-sized rodent almost indistinguishable from the closely related eastern woodrat, although slightly larger on average, and often with longer whiskers. Adults typically range from in total length, including a tail measuring . Males weigh on average, while females are slightly smaller, weighing an average of . It is the second-largest member of the native North American rats, and can weigh up to a pound, roughly the size of an eastern gray squirrel. The fur is long, soft, and brownish-gray or cinnamon in color, while the undersides and feet are white. They have large eyes, and naked ears. Their most distinguishing feature is their tails: while the tails of European rats are naked with only sligh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neotoma Cinerea
The bushy-tailed woodrat, or packrat (''Neotoma cinerea'') 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 bushy-tailed woodrat is the original "pack rat", the species in which the trading habit is most pronounced. It has a strong preference for shiny objects and will drop whatever it may be carrying in favor of a coin or a spoon. Description Bushy-tailed woodrats can be identified by their large, rounded ears, and their long, bushy tails. They are usually brown, peppered with black hairs above with white undersides and feet. The top coloration may vary from buff to almost black. The tail is squirrel-like - bushy, and flattened from base to tip. These woodrats are good climbers and have sharp claws. They use their long tails for balance while climbing and jumping, and for added warmth. These rodents are sexually dim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neotoma Macrotis
The big-eared woodrat (''Neotoma macrotis'') 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. The big-eared woodrat is light to dark brown in color, often with a lighter underside. It has characteristically large mobile ears, large eyes, and a long, fur covered tail. It is a primarily arboreal herbivore and functions as an important keystone species in oak and other forest ecosystems. Taxonomy Although often misconstrued to be related to common rats, woodrats are not in fact part of the genus ''Rattus'' and are quite biologically and behaviorally different from them.

Neotoma Fuscipes
The dusky-footed woodrat (''Neotoma fuscipes'') is a species of nocturnal rodent in the family Cricetidae. Nicknames include "packrats" or "trade rats" because of their tendency to hoard things, build large domed dens, and "trade" by dropping then picking up another object for it. 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 (when they are most vulnerable to predation), 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. They are similar in appearance to the common rat species ''Rattus rattus'' and ''Rattus norvegicus'', but with larger ears and eyes ...

Neotoma Nelsoni
Nelson's woodrat (''Neotoma nelsoni'') is a species of rodent in the family Cricetidae. It is endemic to Mexico, where it is known only from the eastern slopes of the volcanoes Orizaba and Cofre de Perote. Due to the small geographic range, isolation, and low population, the Nelson's woodrat has a higher risk for extinction. The distribution and population sizes are small. The population exists in geographic isolation, which prevents gene flow Location The Nelson's woodrat can only be found on the eastern side of the volcanoes Pico de Orizaba and Cofre de Perote in Mexico. The estimated area for where this species is located is 1,350 km2. This area includes steep slopes, coffee plantations, and a cloud forest. They are found at elevation ranging from 970 to 2,770 m, In a climate that is humid and warm. Preferred locations have Rain throughout all months of the year. Vegetation in the area is tropical rain forest Characteristics The upper body is cinnamon color wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neotoma Findleyi
''Neotoma findleyi'', or Findley's woodrat, is an extinct species of rodent that was found in New Mexico. It lived during the Pleistocene, going extinct during the Rancholabrean. Naming The rat was named in honour of James S. Findley, who trained a generation of mammalogists while at the University of New Mexico and was instrumental in building a greater knowledge of Southwestern mammals. Diagnosis The holotype was found in the caves of New Mexico. Ages from the cave sites are 29,290 ± 1060 and 33,590 ± 1500 BP, respectively. They are thought to be somewhat older on the based on the faunal makeup from these around these sites as well as with problems with ages based on carbonates from the bones alone. Findley's woodrat was between the size of the Mexican woodrat (''N. mexicana'') and bushy-tailed woodrat The bushy-tailed woodrat, or packrat (''Neotoma cinerea'') is a species of rodent in the family Cricetidae found in Canada and the United States.
