Packrat
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.

Neotoma Lepida
The desert woodrat (''Neotoma lepida'') is a species of pack rat native to desert regions of western North America. Description Desert woodrats are relatively small for pack rats, measuring in length, including a tail. They weigh from , with males being larger than females. Their coloring varies between individuals, and can be anything from pale gray to cinnamon to near-black. Regardless of the color on the rest of the body, however, the animal's underparts and feet are always white, while the otherwise pale fur on the throat region is gray at its base. The tail is distinctly bicolored, and has more hair, and fewer visible scales, than the tails of brown rats. Desert woodrats have a narrow snout, long whiskers, and relatively long ears that are almost the length of the hind feet. Distribution and habitat Desert woodrats range from southeastern Oregon and southwestern Idaho, south through Nevada and western Utah Utah ( , ) is a state in the Mountain West subregio ...

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 subsequently s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 se ...

Cenozoic
The Cenozoic ( ; ) is Earth's current geological era, representing the last 66million years of Earth's history. It is characterised by the dominance of mammals, birds and flowering plants, a cooling and drying climate, and the current configuration of continents. It is the latest of three geological eras since complex life evolved, preceded by the Mesozoic and Paleozoic. It started with the Cretaceous–Paleogene extinction event, when many species, including the non-avian dinosaurs, became extinct in an event attributed by most experts to the impact of a large asteroid or other celestial body, the Chicxulub impactor. The Cenozoic is also known as the Age of Mammals because the terrestrial animals that dominated both hemispheres were mammalsthe eutherians (placentals) in the northern hemisphere and the metatherians (marsupials, now mainly restricted to Australia) in the southern hemisphere. The extinction of many groups allowed mammals and birds to greatly diversify so that l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Neotoma Micropus
The Southern Plains woodrat (''Neotoma micropus'') 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. References *Musser, G. G. and M. D.

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. * Elevation range: 970–2,770 m * Climate: Humid and warm * Precipitation: Rain throughout all months of the year * Vegetation: Tropical rain forest Characteristics * Upper Body ** Cinnamon color ** White throat ** Grayish brown cheeks ** Short and silky hairs * ...

Deer Mice
Deer or true deer are hoofed ruminant mammals forming the family Cervidae. The two main groups of deer are the Cervinae, including the muntjac, the elk (wapiti), the red deer, and the fallow deer; and the Capreolinae, including the reindeer (caribou), white-tailed deer, the roe deer, and the moose. Male deer of all species (except the water deer), as well as female reindeer, grow and shed new antlers each year. In this they differ from permanently horned antelope, which are part of a different family (Bovidae) within the same order of even-toed ungulates (Artiodactyla). The musk deer (Moschidae) of Asia and chevrotains (Tragulidae) of tropical African and Asian forests are separate families that are also in the ruminant clade Ruminantia; they are not especially closely related to Cervidae. Deer appear in art from Paleolithic cave paintings onwards, and they have played a role in mythology, religion, and literature throughout history, as well as in heraldry, such as red dee ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
