The Saint Lawrence Island shrew (''Sorex jacksoni'') is a species of mammal in the family Soricidae. It is found only on Alaska Alaska ( ) is a non-contiguous U.S. state on the northwest extremity of North America. Part of the Western United States region, it is one of the two non-contiguous U.S. states, alongside Hawaii. Alaska is also considered to be the north ...'s St. Lawrence Island.

Eugene Raymond Hall
Eugene Raymond Hall (11 May 1902, Imes, Kansas – 2 April 1986, Lawrence, Kansas) was an American mammalogist. Biology Hall graduated from the University of Kansas with A.B. in 1924 and from the University of California, Berkeley with M.A. in 1925 and Ph.D. in 1928. His doctoral dissertation, under the direction of Joseph Grinnell, was a taxonomic revision of the American weasels. At U.C. Berkeley, Hall was a research assistant from 1926 to 1927, curator of the Museum of Vertebrate Zoology from 1927 to 1944, an assistant professor of vertebrate zoology from 1930 to 1937, and an associate professor from 1937 to 1944. At the University of Kansas he was a full professor and chair of the zoology department from 1944 to 1967, when he retired as professor emeritus. He was also the director of the University of Kansas Natural History Museum from 1944 to 1967. He persuaded Ralph Nicholson Ellis (1908–1945) to will his collection of books and papers to the University of Kansas. (In 19 ...

Raymond Gilmore
Raymond Maurice Gilmore (1 January 1907 - 31 December 1983) was an American zoologist and a recognized authority on whales. He conducted the first census of California gray whales and is credited with creating public interest in their conservation by leading the earliest whale-watching excursions for the San Diego Natural History Museum. Guiding groups of whale-watchers beginning in 1958, Gilmore was the first onboard naturalist in San Diego; he continued his popular excursions for 25 years. Known as the father of whale watching, Gilmore was the leading expert on California gray whales. Biography Gilmore was born in Ithaca, New York, on January 1, 1907, the son of Elizabeth M. Hitchcock and agronomist John W. Gilmore. He was raised in Honolulu, Hawai'i and Berkeley, California. Gilmore received both his A.B. degree (1930, Zoology) and his M.A. (1933, Zoology and Anthropology) from the University of California, Berkeley. He was the Virginia Barret Gibbs Scholar at Harvard U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammal
A mammal () is a vertebrate animal of the Class (biology), class Mammalia (). Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three Evolution of mammalian auditory ossicles, middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors Genetic divergence, diverged in the Carboniferous Period over 300 million years ago. Around 6,640 Neontology#Extant taxon, extant species of mammals have been described and divided into 27 Order (biology), orders. The study of mammals is called mammalogy. The largest orders of mammals, by number of species, are the rodents, bats, and eulipotyphlans (including hedgehogs, Mole (animal), moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the Artiodactyl, even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including Felidae, ...

Alaska
Alaska ( ) is a non-contiguous U.S. state on the northwest extremity of North America. Part of the Western United States region, it is one of the two non-contiguous U.S. states, alongside Hawaii. Alaska is also considered to be the northernmost, westernmost, and easternmost (the Aleutian Islands cross the 180th meridian into the eastern hemisphere) state in the United States. It borders the Canadian territory of Yukon and the province of British Columbia to the east. It shares a western maritime border, in the Bering Strait, with Russia's Chukotka Autonomous Okrug. The Chukchi and Beaufort Seas of the Arctic Ocean lie to the north, and the Pacific Ocean lies to the south. Technically, it is a semi-exclave of the U.S., and is the largest exclave in the world. Alaska is the largest U.S. state by area, comprising more total area than the following three largest states of Texas, California, and Montana combined, and is the seventh-largest subnational division i ...

Sorex
The genus ''Sorex'' includes many of the common shrews of Eurasia and North America, and contains at least 142 known species and subspecies. Members of this genus, known as long-tailed shrews, are the only members of the tribe Soricini of the subfamily Soricinae (red-toothed shrews). They have 32 teeth. These animals have long, pointed snouts, small ears, which are often not visible, and scent glands located on the sides of their bodies. As their eyesight is generally poor, they rely on hearing and smell to locate their prey, mainly insects. Some species also use echolocation. Distinguishing between species without examining the dental pattern is often difficult. In some species, a female shrew and her dependent young form "caravans", in which each shrew grasps the rear of the shrew in front, when changing location. Species * Genus ''Sorex'' – most basal of the genera ** Kashmir pygmy shrew (''S. planiceps'') – India and Pakistan ** Tibetan shrew (''S. thibetanus'') – ...

Endemic Mammals Of The United States
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becoming ...

Taxonomy Articles Created By Polbot
280px, Generalized scheme of taxonomy Taxonomy is a practice and science concerned with classification or categorization. Typically, there are two parts to it: the development of an underlying scheme of classes (a taxonomy) and the allocation of things to the classes (classification). Originally, taxonomy referred only to the classification of organisms on the basis of shared characteristics. Today it also has a more general sense. It may refer to the classification of things or concepts, as well as to the principles underlying such work. Thus a taxonomy can be used to organize species, documents, videos or anything else. A taxonomy organizes taxonomic units known as "taxa" (singular "taxon"). Many are hierarchies. One function of a taxonomy is to help users more easily find what they are searching for. This may be effected in ways that include a library classification system and a search engine taxonomy. Etymology The word was coined in 1813 by the Swiss botanist A ...
