Ned Hollister
Ned Hollister (November 26, 1876 – November 3, 1924) was an American biologist primarily known for studying mammals. Hollister was born in Delavan, Wisconsin to parents Kinner Newcomb Hollister (1841–1911) and Frances Margaret (Tilden) Hollister (1845–1927). He attended Delavan High School. He married Mabel Pfrimmer in 1908. From 1916 until his death he was Superintendent of the National Zoological Park (United States), National Zoological Park. In 1921 he served as president of the Biological Society of Washington. When Hollister was twelve, he gained an interest in birds as he studied under Ludwig Kumlien, who was a professor at Milton College. At the age of 16, Hollister wrote his first papers on ornithology. At 18, Hollister was elected to the American Ornithologists' Union. Hollister was designated to be the assistant curator of mammals at the U.S. National Museum in 1910. In the year of 1912, Hollister worked for the Smithsonian Institution, Smithsonian. In 1916, Ned Ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rodent
Rodents (from Latin , 'to gnaw') are mammals of the Order (biology), order Rodentia ( ), which are characterized by a single pair of continuously growing incisors in each of the upper and Mandible, lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for 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/ricochetal (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 Mouse, mice, rats, squirrels, prairie dogs, porcupines, beavers, Cavia, guinea pigs, and hamsters. Once included wi ...

Sminthidae
Sminthidae is a family of mouse-like jumping rodents. They are represented by only one extant genus, '' Sicista'', represented by 19 species found throughout most of Eurasia, from central Europe east to Siberia, and south to southern China. However, they were much more diverse and had a much wider range in prehistory, having multiple genera and being found not only in Eurasia but also throughout North America, where they existed up to the early Pleistocene. They have a well-attested fossil record which dates as far back as the early Oligocene. They were formerly classified as the subfamily Sicistinae in the family Dipodidae alongside the jerboas and jumping mice, but phylogenetic evidence supports all three of these belonging to distinct families, thus leaving only the jerboas in Dipodidae.

Sicista
Birch mice (genus ''Sicista'') are small jumping rodents that resemble mice with long, tufted tails and very long hind legs, allowing for remarkable leaps. They are the only extant members of the family Sminthidae. They are native to Eurasian forests and steppes. All variants possess a long tail of of length and weigh about . Head and body length of and hind foot length of . The animal's skin color is light brown or dark-brown to brownish yellow on the upper side and paler on the underside, but generally brownish. Birch mice have a vast geographic distribution in that they inhabit a wide variety of habitats, from semiarid areas to subalpine meadows. Although they have a diverse region of areas, their molecular and anatomical markers have claimed that Birch mice originated from Central Asia. Birch mice have a systematic of the genus of ''Sicista'', they look at the male reproductive organs and cytogenic data. Species Nineteen species are listed by the American Society of Mamm ...

Mammals Of Russia
This is a list of the mammal species recorded in Russia. There are 266 mammal species in Russia, of which five are critically endangered, thirteen are endangered, twenty-six are vulnerable, and six are near threatened. One of the species listed for Russia is extinct and one can no longer be found in the wild. All the mammals of Russia are in the subclass Theria and infraclass Eutheria, being all Placentalia, placental. The following tags are used to highlight each species' conservation status as assessed by the International Union for Conservation of Nature: Order: Rodentia (rodents) Rodents make up the largest order of mammals, with over 40% of mammalian species. They have two incisors in the upper and lower jaw which grow continually and must be kept short by gnawing.

Mammals Of Central Asia
A mammal () is a vertebrate animal of the 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 middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors diverged in the Carboniferous Period over 300 million years ago. Around 6,640 extant species of mammals have been described and divided into 27 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, moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including cats, dogs, and seals). Mammals are the only living members of Synapsida; this clade, together with Sauropsida (reptiles and birds), constitutes the large ...

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 ...
