Soemmerring's Gazelle
Soemmerring's gazelle (''Nanger soemmerringii''), also known as the Abyssinian mohr, is a gazelle species native to the Horn of Africa (Djibouti, Eritrea, Ethiopia, Somalia and South Sudan). The species was described and given its binomen by German physician Philipp Jakob Cretzschmar in 1828. Three subspecies are recognized. It is possibly no longer present in Sudan. Since 1986, Soemmerring's gazelle has been classified as Vulnerable by the International Union for Conservation of Nature (IUCN). Taxonomy and evolution The scientific name of Soemmerring's gazelle is ''Nanger soemmerringii''. Formerly considered member of genus ''Gazella'' within the subgenus ''Nanger'' before ''Nanger'' was elevated to genus status, Soemmerring's gazelle is one of members of the genus ''Nanger'' and is classified under the family Bovidae.

Thomson's Gazelle
Thomson's gazelle (''Eudorcas thomsonii'') is one of the best known species of gazelles. It is named after explorer Joseph Thomson and is sometimes referred to as a "tommie". It is considered by some to be a subspecies of the red-fronted gazelle and was formerly considered a member of the genus ''Gazella'' within the subgenus ''Eudorcas'', before ''Eudorcas'' was elevated to genus status. Thomson's gazelles can be found in numbers exceeding 200,000 in Africa and are recognized as the most common type of gazelle in East Africa. A small fast antelope, the Thomson's gazelle is claimed to have top speeds up to . It is the fourth-fastest land animal, after the cheetah (its main predator), pronghorn, and springbok. Taxonomy and etymology The current scientific name of Thomson's gazelle is ''Eudorcas thomsonii''. It is a member of the genus ''Eudorcas'' and is classified under the family Bovidae. Thomson's gazelle was first described by British zoologist Albert Günther in 1884. The rel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Samuel Thomas Von Sömmerring
Samuel Thomas von Sömmerring (28 January 1755 – 2 March 1830) was a German physician, anatomist, anthropologist, paleontologist and inventor. Sömmerring discovered the macula in the retina of the human eye. His investigations on the brain and the nervous system, on the sensory organs, on the embryo and its malformations, on the structure of the lungs, etc., made him one of the most important German anatomists. Career Sömmerring was born in Thorn (Toruń), Royal Prussia (a province of the Crown of Poland) as the ninth child of the physician Johann Thomas Sömmerring. In 1774 he completed his education in Thorn and began to study medicine at the University of Göttingen. He visited Petrus Camper lecturing at the University in Franeker. He became a professor of anatomy at the Collegium Carolinum (housed in the Ottoneum, now a Natural History Museum) in Kassel and, beginning in 1784, at the University of Mainz. There he was for five years the dean of the medical faculty. Aft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Physicist
A physicist is a scientist who specializes in the field of physics, which encompasses the interactions of matter and energy at all length and time scales in the physical universe. Physicists generally are interested in the root or ultimate causes of phenomena, and usually frame their understanding in mathematical terms. Physicists work across a wide range of research fields, spanning all length scales: from sub-atomic and particle physics, through biological physics, to cosmological length scales encompassing the universe as a whole. The field generally includes two types of physicists: experimental physicists who specialize in the observation of natural phenomena and the development and analysis of experiments, and theoretical physicists who specialize in mathematical modeling of physical systems to rationalize, explain and predict natural phenomena. Physicists can apply their knowledge towards solving practical problems or to developing new technologies (also known as applie ...

Scientific Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zoolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bovidae
The Bovidae comprise the biological family of cloven-hoofed, ruminant mammals that includes cattle, bison, buffalo, antelopes, and caprines. A member of this family is called a bovid. With 143 extant species and 300 known extinct species, the family Bovidae consists of 11 (or two) major subfamilies and thirteen major tribes. The family evolved 20 million years ago, in the early Miocene. The bovids show great variation in size and pelage colouration. Excepting some domesticated forms, all male bovids have two or more horns, and in many species, females possess horns, too. The size and shape of the horns vary greatly, but the basic structure is always one or more pairs of simple bony protrusions without branches, often having a spiral, twisted or fluted form, each covered in a permanent sheath of keratin. Most bovids bear 30 to 32 teeth. Most bovids are diurnal. Social activity and feeding usually peak during dawn and dusk. Bovids typically rest before dawn, during midday ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Gazella
A gazelle is one of many antelope species in the genus ''Gazella'' . This article also deals with the seven species included in two further genera, ''Eudorcas'' and ''Nanger'', which were formerly considered subgenera of ''Gazella''. A third former subgenus, ''Procapra'', includes three living species of Asian gazelles. Gazelles are known as swift animals. Some are able to run at bursts as high as or run at a sustained speed of . Gazelles are found mostly in the deserts, grasslands, and savannas of Africa; but they are also found in southwest and central Asia and the Indian subcontinent. They tend to live in herds, and eat fine, easily digestible plants and leaves. Gazelles are relatively small antelopes, most standing high at the shoulder, and are generally fawn-colored. The gazelle genera are ''Gazella'', ''Eudorcas'', and ''Nanger''. The taxonomy of these genera is confused, and the classification of species and subspecies has been an unsettled issue. Currently, the genu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
