Gophers
Pocket gophers, commonly referred to simply as gophers, are burrowing rodents of the family Geomyidae. The roughly 41 speciesSearch results for "Geomyidae" on thASM Mammal Diversity Database are all endemic to North and Central America. They are commonly known for their extensive tunneling activities and their ability to destroy farms and gardens. The name "pocket gopher" on its own may refer to any of a number of genera within the family Geomyidae. These are the "true" gophers, but several ground squirrels in the distantly related family Sciuridae are often called "gophers", as well. The origin of the word "gopher" is uncertain; the French ''gaufre'', meaning waffle, has been suggested, on account of the gopher tunnels resembling the honeycomb-like pattern of holes in a waffle; another suggestion is that the word is of Muskogean origin. Description Gophers weigh around , and are about in body length, with a tail long. A few species reach weights approaching . Within any s ...

Botta's Pocket Gopher
Botta's pocket gopher (''Thomomys bottae'') is a pocket gopher native to western North America. It is also known in some sources as valley pocket gopher, particularly in California. Both the specific and common names of this species honor Paul-Émile Botta, a naturalist and archaeologist who collected mammals in California in 1827 and 1828. Description Botta's pocket gopher is a medium-sized gopher, with adults reaching a length of , including a tail of . The overall dental formula is . Males are larger, with a weight of , compared with in the females. Male pocket gophers are widely believed to continue growing throughout their life. However, size variation would indicate that some males are predisposed to be larger than others, and the largest male may not be the oldest. Coloration is highly variable, and has been used to help distinguish some of the many subspecies; it may also change over the course of a year as the animals molt. Both albino and melanistic individuals have al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heterogeomys
''Heterogeomys'' is a genus of rodent in the family Geomyidae, found in Mexico, Central America and Colombia. ''Heterogeomys'' are a small genus of rodents commonly known as pocket gophers, though the term applies to all genera within the family Geomyidae. The name pocket gopher was earned for this family because of their fur lined cheek pouches that can be used for carrying food. These pouches can also be turned inside out. Species of ''Heterogeomys'' are regarded as pests, one of less than 5% of rodent species classified as pests, and the history of man's attempts to control their populations reaches back into Mayan times. Despite some efforts to the contrary, populations of ''Heterogeomys'' seem to be on a general upwards trend. Furthermore, all of the species of ''Heterogeomys'' are considered to be of Least Concern in the World Status Key. Taxonomy In 1895, C. H Meriam described 3 genera of pocket gophers: ''Heterogeomys'', ''Macrogeomys'', and ''Orthogeomys''. In th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rodent
Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for New Zealand, Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/richochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and pikas, whose i ...

Soil Biomantle
The soil biomantle can be described and defined in several ways. Most simply, the soil biomantle is the organic-rich bioturbated upper part of the soil, including the topsoil where most biota live, reproduce, die, and become assimilated. The biomantle is thus the upper zone of soil that is predominantly a product of organic activity and the area where bioturbation is a dominant process. Soil bioturbation consists predominantly of three subsets: ''faunalturbation'' (animal burrowings), ''floralturbation'' (root growth, tree-uprootings), and ''fungiturbation'' (mycelia growth). All three processes promote soil parent material destratification, mixing, and often particle size sorting, leading with other processes to the formation of soil and its horizons. While the general term bioturbation refers mainly to these three mixing processes, unless otherwise specified it is commonly used as a synonym to faunalturbation (animal burrowings). One- and two-layered biomantles, soil stonelayers ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zygogeomys
The Michoacan pocket gopher (''Zygogeomys trichopus'') is a species of rodent in the family Geomyidae. It is monotypic within the genus ''Zygogeomys''. It is endemic to Mexico where its natural habitat is temperate, high-altitude forests. Its numbers are declining and it is listed by the IUCN as "endangered". Description The Michoacan pocket gopher is a small animal with short, dense, black, lustrous fur and a hairless tail. The eyes are small and deep-set and there is a pad-like region of bare skin just behind the nostrils. It is docile when caught, making no attempt to bite as do other pocket gophers. Distribution and habitat The Michoacan pocket gopher is endemic to the Trans-Mexican Volcanic Belt mountain range in central southern Mexico, where it occurs in four discrete locations near west of Lake Pátzcuaro at altitudes over . The fossil record shows that members of the genus ''Zygogeomys'', including two other now extinct species, were widespread in the late Pliocene epoc ...

Hoarding (animal Behavior)
Hoarding or caching in animal behavior is the storage of food in locations hidden from the sight of both conspecifics (animals of the same or closely related species) and members of other species. Most commonly, the function of hoarding or caching is to store food in times of surplus for times when food is less plentiful. However, there is evidence that some amount of caching or hoarding is done in order to ripen the food, called ripening caching. The term hoarding is most typically used for rodents, whereas caching is more commonly used in reference to birds, but the behaviors in both animal groups are quite similar. Hoarding is done either on a long-term basis – cached on a seasonal cycle, with food to be consumed months down the line – or on a short-term basis, in which case the food will be consumed over a period of one or several days. Some common animals that cache their food are rodents such as hamsters and squirrels, and many different bird species, such as rooks and ...

Burrow
An Eastern chipmunk at the entrance of its burrow A burrow is a hole or tunnel excavated into the ground by an animal to construct a space suitable for habitation or temporary refuge, or as a byproduct of locomotion. Burrows provide a form of shelter against predation and exposure to the elements, and can be found in nearly every biome and among various biological interactions. Many animal species are known to form burrows. These species range from small invertebrates, such as the ''Corophium arenarium'', to very large vertebrate species such as the polar bear. Burrows can be constructed into a wide variety of substrates and can range in complexity from a simple tube a few centimeters long to a complex network of interconnecting tunnels and chambers hundreds or thousands of meters in total length; an example of the latter level of complexity, a well-developed burrow, would be a rabbit warren.

Pest (organism)
A pest is any animal or plant harmful to humans or human concerns. The term is particularly used for creatures that damage crops, livestock, and forestry or cause a nuisance to people, especially in their homes. Humans have modified the environment for their own purposes and are intolerant of other creatures occupying the same space when their activities impact adversely on human objectives. Thus, an elephant is unobjectionable in its natural habitat but a pest when it tramples crops. Some animals are disliked because they bite or sting; snake Snakes are elongated, Limbless vertebrate, limbless, carnivore, carnivorous reptiles of the suborder Serpentes .
