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. 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 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 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 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.

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''.
