Pack Rat
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, Reithrodontomys, 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 *** ''Anthony's woodrat, Neotoma bryanti anthonyi'' - Anthony's woodrat *** †''Bunker's woodrat, Neotoma bryanti bunkeri'' - Bunker's woodrat *** †''San Martín Island woodrat, Neotoma bryanti martinensis'' - San Martín Island woodrat ** ''Neotoma chrysomelas'' - Nicaraguan woodrat ** ''Neotoma devia'' - Ar ...

Cenozoic
The Cenozoic Era ( ; ) is Earth's current geological era, representing the last 66million years of Earth's history. It is characterized by the dominance of mammals, insects, birds and angiosperms (flowering plants). It is the latest of three geological eras of the Phanerozoic Eon, preceded by the Mesozoic and Paleozoic. The Cenozoic 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 and to some extent South America) in the Southern Hemisphere. The extinction of many groups allowed mammals and birds to greatly diversify so that large m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neotoma Leucodon
''Neotoma leucodon'' is a species of rodent in the family Cricetidae. Although originally named from San Luis Potosí, Mexico, as a species by Clinton Hart Merriam, the white-toothed woodrat was long considered to be a synonym of the white-throated woodrat (''Neotoma albigula''). 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 habitat preferences of the two species appear similar, with woodland to desert habitats preferred. Almost invariably, cacti, especially cholla and prickly pear (''Opuntia ''Opuntia'', commonly called the prickly pear cactus, is a genus of flowering plants in the cactus family Cactaceae, many known for their flavorful fruit and showy flowers. Cacti are native to the Americas, and are well adapted to arid clima ...''), are present, and form an integral portion of their diets. In general, the data p ...

Deer Mice
''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] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Species
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. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists 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. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neotoma Stephensi
Stephen's woodrat (''Neotoma stephensi'') is a species of rodent in the family Cricetidae found in Arizona, New Mexico and Utah in the United States. Description Individuals of ''N. stephensi'' are small with long, silky fur and a slightly bushy tail. They are colored grayish buff with a paler head and a pinkish buff belly. They have white fur on their pectoral, inguinal (groin), foot, and occasionally throat regions. Their ears and topside of their tail have grayish-brown fur. They have a short and broad skull with a small and smoothly rounded braincase; broad, flat frontal region; large bullae; and a first upper molar without an antero-internal sulcus. Similar species ''N. stephensi'' resembles the species '' Neotoma lepida'', but can be distinguished by its larger hind foot, color, and the shape of its skull, which is generally larger with a longer toothrow, larger interparietal bone, and smaller bullae than that of ''N. lepida''.

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 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'': White Sands woodrat, is white in coloration and found only at White Sands National Park in New Mexico. Habitat ''N. micropus'' inhabits semi-arid brush-lands and rocky outcrops. It favors cactus, mesquite and thickets. Dens are constructed underneath shrubs and cacti, often prickly pears. They have a large central chamber that serve as the nest and side chambers around for storing food. The female of the species tends to use the same den throughout her adult life. Other organisms sometimes co-inhabit the dens with them, such as desert shrews and assassin bugs. The 'house' section is large and around 4-5' (1.2-1.5 m) high. It's composed of sticks, parts of cacti, thorns and other assorted debris. Description The Southern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neotoma Mexicana
The Mexican woodrat (''Neotoma mexicana'') is a medium-sized pack rat. Distribution and habitat It ranges from the United States (Utah, Colorado, New Mexico and parts of Arizona and Trans-Pecos Texas) south to Honduras. Although occurring at lower elevations during the Pleistocene, it generally is limited now to highlands supporting open coniferous forests or woodlands. In a few places, it occurs in lower country where lava or boulder fields occur; presumably the presence of spaces extending far below the surface enables survival. Like most members of the genus living in rocky areas, dens tend to take advantage of crevices, rock shelters, and caves; stick nests are relatively rare. Taxonomy The type locality is near Chihuahua, Mexico. Some 26 species names have been applied to populations of the Mexican woodrat and are now considered synonyms. Description and diet The animal averages a bit over in total length and weighs . Their diets tend to be generalist, with a wide varie ...
