Chihuahuan Grasshopper Mouse
Mearns's grasshopper mouse or the Chihuahuan grasshopper mouse (''Onychomys arenicola'') is a grasshopper mouse found in southwestern New Mexico, West Texas, and north-central Mexico. They are similar to ''Onychomys torridus'', but differ in karyotype and size. This mouse is smaller in every regard except for the nasal length of the skull. They are found in semiarid habitat, prairie, and scrub. They feed largely on insects and other invertebrates, including scorpions. They also feed on small muroid rodents and pocket mice Perognathinae is a subfamily of rodents consisting of two genera of pocket mice. Most species live in complex burrows within the deserts and grasslands of western North America, They feed mostly on seeds and other plant parts, which they carry i .... References *Nowak, R.

Grasshopper Mouse
Grasshopper mice are rodents of the genus ''Onychomys'', occurring in North America. They feed on insects and other arthropods. Biology The three species in this genus of New World mice are only distantly related to the common house mouse, ''Mus musculus''. They are endemic to the United States and Mexico. The southern grasshopper mouse has around a long body and a tail that is generally long. Its behavior is distinct from other mice. It is a carnivorous rodent, dining on insects (such as grasshoppers), worms, spiders, centipedes, scorpions, snakes, and even other mice. It also stalks its prey in the manner of a cat, sneaking up quietly, and defends its territory by "howling" like a small wolf. The grasshopper mouse is known to be immune to various venoms released by its prey (scorpions, snakes, etc.). Grasshopper mice are nocturnal and avoid exposure to bright light.

West Texas
West Texas is a loosely defined region in the U.S. state of Texas, generally encompassing the arid and semiarid lands west of a line drawn between the cities of Wichita Falls, Abilene, and Del Rio. No consensus exists on the boundary between East Texas and West Texas. While most Texans understand these terms, no boundaries are officially recognized and any two individuals are likely to describe the boundaries of these regions differently. Walter Prescott Webb, American historian and geographer, suggested that the 98th meridian separates East and West Texas; Texas writer A.C. Greene proposed that West Texas extends west of the Brazos River. Use of a single line, though, seems to preclude the use of other separators, such as an area— Central Texas. Unlike East Texas, West Texas is not generally considered to be part of the American South, and the dry, desert climate is often more associated with the American Southwest. West Texas is often subdivided according to disti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Onychomys Torridus
The southern grasshopper mouse or scorpion mouse (''Onychomys torridus'') is a species of predatory rodent in the family Cricetidae, native to Mexico and the states of Arizona, California, Nevada, New Mexico, and Utah in the United States. Notable for its resistance to venom, it routinely preys on the highly venomous Arizona bark scorpion. Description The southern grasshopper mouse is a robust, small, nocturnal species that typically forms monogamous pairs. They have a short tail, growing to a total length of . The head, back and sides are pinkish- or grayish-brown while the underparts are white, the two colors being distinctly separated. The tail is club-shaped, short and broad, the anterior part being the same color as the body and the tip being white. Biology The southern grasshopper mouse feeds almost entirely on arthropods, such as beetles, grasshoppers and scorpions. In addition to arthropods, it is known to prey upon the little pocket mouse (''Perognathus longimembris'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karyotype
A karyotype is the general appearance of the complete set of metaphase chromosomes in the cells of a species or in an individual organism, mainly including their sizes, numbers, and shapes. Karyotyping is the process by which a karyotype is discerned by determining the chromosome complement of an individual, including the number of chromosomes and any abnormalities. A karyogram or idiogram is a graphical depiction of a karyotype, wherein chromosomes are organized in pairs, ordered by size and position of centromere for chromosomes of the same size. Karyotyping generally combines light microscopy and photography, and results in a photomicrographic (or simply micrographic) karyogram. In contrast, a schematic karyogram is a designed graphic representation of a karyotype. In schematic karyograms, just one of the sister chromatids of each chromosome is generally shown for brevity, and in reality they are generally so close together that they look as one on photomicrographs as well ...

Prairie
Prairies are ecosystems considered part of the temperate grasslands, savannas, and shrublands biome by ecologists, based on similar temperate climates, moderate rainfall, and a composition of grasses, herbs, and shrubs, rather than trees, as the dominant vegetation type. Temperate grassland regions include the Pampas of Argentina, Brazil and Uruguay, and the steppe of Ukraine, Russia and Kazakhstan. Lands typically referred to as "prairie" tend to be in North America. The term encompasses the area referred to as the Geography of North America, Interior Lowlands of Canada, the United States, and Mexico, which includes all of the Great Plains as well as the wetter, hillier land to the east. In the U.S., the area is constituted by most or all of the states of North Dakota, South Dakota, Nebraska, Kansas, and Oklahoma, and sizable parts of the states of Montana, Wyoming, Colorado, New Mexico, Texas, Missouri, Iowa, Illinois, Indiana, Wisconsin, and western and southern Minnesota.

Scorpion
Scorpions are predatory arachnids of the order Scorpiones. They have eight legs, and are easily recognized by a pair of grasping pincers and a narrow, segmented tail, often carried in a characteristic forward curve over the back and always ending with a stinger. The evolutionary history of scorpions goes back 435 million years. They mainly live in deserts but have adapted to a wide range of environmental conditions, and can be found on all continents except Antarctica. There are over 2,500 described species, with 22 extant (living) families recognized to date. Their taxonomy is being revised to account for 21st-century genomic studies. Scorpions primarily prey on insects and other invertebrates, but some species hunt vertebrates. They use their pincers to restrain and kill prey, or to prevent their own predation. The venomous sting is used for offense and defense. During courtship, the male and female grasp each other's pincers and dance while he tries to move her onto his s ...

Muroid Rodents
The Muroidea are a large superfamily of rodents, including mice, rats, voles, hamsters, lemmings, gerbils, and many other relatives. Although the Muroidea originated in Eurasia, they occupy a vast variety of habitats on every continent except Antarctica. Some authorities have placed all members of this group into a single family, Muridae, due to difficulties in determining how the subfamilies are related to one another. Many of the families within the Muroidea superfamily have more variations between the families than between the different clades. A possible explanation for the variations in rodents is because of the location of these rodents; these changes could have been due to radiation or the overall environment they migrated to or originated in. The following taxonomy is based on recent well-supported molecular phylogenies. The muroids are classified in six families, 19 subfamilies, around 280 genera, and at least 1,750 species.

Pocket Mice
Perognathinae is a subfamily of rodents consisting of two genera of pocket mice. Most species live in complex burrows within the deserts and grasslands of western North America, They feed mostly on seeds and other plant parts, which they carry in their fur-lined cheek pouches to their burrows. Description There are about twenty-six members of the subfamily Perognathinae divided among two genera. They are all small rodents. Adaptations include partially fused vertebrae in the neck, short fore limbs and much enlarged bullae (bubble-shaped bones in the skull). The dental formula is 1/1, 0/0, 1/1, 3/3 making twenty teeth in total. The molars have two-lobed cusps. The upper incisors are grooved and the enamel on the molars is quickly worn away by chewing leaving the dentine exposed. The check teeth have roots. Fur-lined cheek pouches are a feature across the family Heteromyidae. They have openings near the mouth and extend backwards along the sides of the neck. The fur on the animal ...
