Underwood's Pocket Gopher
Underwood's pocket gopher (''Heterogeomys underwoodi'') is a species of rodent in the family Geomyidae. It is endemic to Costa Rica. Some authors classify it in the genus ''Orthogeomys'', but recent research has allowed this and its related species to be classified in the genus ''Heterogeomys ''Heterogeomys'' is a genus of rodent in the family Geomyidae, found in Mexico, Central America and Colombia.

Wilfred Hudson Osgood
Wilfred Hudson Osgood (December 8, 1875 – June 20, 1947) was an American zoologist. Biography Osgood was born in Rochester, New Hampshire, the oldest child of a family of watchmakers. The family moved to California in 1888 and he went to study in Santa Clara, California, Santa Clara and San Jose, California, San Jose. He joined in the activities of the Cooper Ornithological Club and found company in wikisource:Author:Chester Barlow, Chester Barlow and Rollo Beck, Rollo H. Beck. He taught at a school in Arizona for a year and then moved to the newly formed Stanford University, where he came to meet Charles Henry Gilbert, Charles H. Gilbert and David Starr Jordan. He joined the staff of the Bureau of Economic Ornithology and Mammalogy, of the United States Department of Agriculture at the age of 22. This group later became the Bureau of Biological Survey under Clinton Hart Merriam. In 1909 he moved to the Field Museum of Natural History in Chicago, where he was assistant curator o ...

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 ...

Endemic
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Orthogeomys
The giant pocket gopher (''Orthogeomys grandis'') is a species of rodent in the family Geomyidae. It is found in Mexico, Guatemala, El Salvador and Honduras.

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 ...

Mammals Described In 1931
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla ( cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together wi ...

Least Concern Biota Of North America
Comparison is a feature in the morphology (linguistics), morphology or syntax (linguistics), syntax of some languages whereby adjectives and adverbs are inflection, inflected to indicate the relative degree of the property they define exhibited by the word or phrase they modify or describe. In languages that have it, the comparative construction expresses quality, quantity, or degree relative to ''some'' other comparator(s). The superlative construction expresses the greatest quality, quantity, or degree—i.e. relative to ''all'' other comparators. The associated grammatical category is degree of comparison. The usual degrees of comparison are the ''positive'', which simply denotes a property (as with the English grammar, English words ''big'' and ''fully''); the ''comparative'', which indicates ''greater'' degree (as ''bigger'' and ''more fully''); and the ''superlative'', which indicates ''greatest'' degree (as ''biggest'' and ''most fully'').
