Orange-throated Whiptail
The orange-throated whiptail (''Aspidoscelis hyperythrus'') is a species of lizard in the family Teiidae. The species was previously placed in the genus ''Cnemidophorus''. Three subspecies are recognized as being valid, including the nominotypical subspecies. Geographic range ''A. hyperythrus'' is native to southern California in the United States, and to the states of Baja California and Baja California Sur in Mexico. Description ''A. hyperythrus'' has five or six light-colored stripes down a black, brown, or grey dorsal side. The middle stripe may be forked at both ends. The species is whitish-yellow or cream on the venter, and has an orange throat (females and juveniles may lack this character). Its head is yellow-brown to olive-colored, and its tongue is forked and flicked continually. It has a snout-to-vent length of . Juveniles of this species have cobalt blue legs and tails. The entire ventral surface of males, including the tail, may be orange, although gravid females ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward Drinker Cope
Edward Drinker Cope (July 28, 1840 – April 12, 1897) was an American zoologist, paleontology, paleontologist, comparative anatomy, comparative anatomist, herpetology, herpetologist, and ichthyology, ichthyologist. Born to a wealthy Quaker family, he distinguished himself as a child prodigy interested in science, publishing his first scientific paper at the age of 19. Though his father tried to raise Cope as a gentleman farmer, he eventually acquiesced to his son's scientific aspirations. Cope had little formal scientific training, and he eschewed a teaching position for field work. He made regular trips to the Western United States, American West, prospecting in the 1870s and 1880s, often as a member of United States Geological Survey, U.S. Geological Survey teams. A personal feud between Cope and paleontologist Othniel Charles Marsh led to a period of intense fossil-finding competition now known as the Bone Wars. Cope's financial fortunes soured after failed mining ventures i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baja California Sur
Baja California Sur, officially the Free and Sovereign State of Baja California Sur, is a state in Mexico. It is the 31st and last state to be admitted, in 1974. It is also the second least populated Mexican state and the ninth-largest state by area.

Reptiles Of Mexico
Reptiles, as commonly defined, are a group of tetrapods with an ectothermic metabolism and Amniotic egg, amniotic development. Living traditional reptiles comprise four Order (biology), orders: Testudines, Crocodilia, Squamata, and Rhynchocephalia. About 12,000 living species of reptiles are listed in the Reptile Database. The study of the traditional reptile orders, customarily in combination with the study of modern amphibians, is called herpetology. Reptiles have been subject to several conflicting Taxonomy, taxonomic definitions. In Linnaean taxonomy, reptiles are gathered together under the Class (biology), class Reptilia ( ), which corresponds to common usage. Modern Cladistics, cladistic taxonomy regards that group as Paraphyly, paraphyletic, since Genetics, genetic and Paleontology, paleontological evidence has determined that birds (class Aves), as members of Dinosauria, are more closely related to living crocodilians than to other reptiles, and are thus nested among re ...

Fauna Of The Southwestern United States
Fauna (: faunae or faunas) is all of the animal life present in a particular region or time. The corresponding terms for plants and fungi are ''flora'' and '' funga'', respectively. Flora, fauna, funga and other forms of life are collectively referred to as '' biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the " Sonoran Desert fauna" or the " Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Modern Greek equivalent of fauna (πανίς or rather πανίδα). ''Fauna'' is also the word for a ...

Aspidoscelis
''Aspidoscelis'' is a genus of whiptail lizards in the family Teiidae. Taxonomy The nomenclature for the genus ''Aspidoscelis'' was published by T.W. Reeder et al. in 2002. Many species that were formerly included in the genus '' Cnemidophorus'' are now considered ''Aspidoscelis'' based upon divergent characters between the two groups. Etymology The name ''Aspidoscelis'' literally means "shield-leg", from the Ancient Greek ("shield") and ("leg"). Species The following species are recognized as being valid. *'' Aspidoscelis angusticeps'' – Yucatán whiptail *'' Aspidoscelis arizonae'' – Arizona striped whiptail *''Aspidoscelis burti'' – canyon spotted whiptail *'' Aspidoscelis calidipes'' – Tepalcatepec Valley whiptail *'' Aspidoscelis carmenensis'' – Carmen Island whiptail *''Aspidoscelis ceralbensis'' – Cerralvo Island whiptail *''Aspidoscelis communis'' – Colima giant whiptail *''Aspidoscelis costatus'' – western Mexico whiptail lizard *''Aspidos ...

Karl Patterson Schmidt
Karl Patterson Schmidt (June 19, 1890 – September 26, 1957) was an American herpetologist. Family Schmidt was the son of George W. Schmidt and Margaret Patterson Schmidt. George W. Schmidt was a German professor, who, at the time of Karl Schmidt's birth, was teaching in Lake Forest, Illinois. His family left the city in 1907 and settled in Wisconsin. They worked on a farm near Stanley, Wisconsin, where his mother and his younger brother died in a fire on August 7, 1935. The brother, Franklin J. W. Schmidt, had been prominent in the then-new field of wildlife management. Karl Schmidt married Margaret Wightman in 1919, and they had two sons, John and Robert. Education In 1913, Schmidt entered Cornell University to study biology and geology. In 1915, he discovered his preference for herpetology during a four-month training course at the Perdee Oil Company in Louisiana. In 1916, he received the degree of Bachelor of Arts and made his first geological expedition to Santo Do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lyman Belding
Lyman Belding (June 12, 1829 – November 22, 1917) was a prominent American ornithologist. Biography Lyman Belding was born to Joshua Belding and Rosetta Cooley Belding on June 12, 1829, at West Farms, Massachusetts, but later moved to Kingston, Pennsylvania when he was about 7 years old, and finally to California. He spent many years on whaling ships, but became fascinated by birds after acquiring his first bird book in 1876. By then he retired in Stockton, California and became a foremost authority on the avifauna of California and Baja California. He died in Stockton on November 22, 1917, and is buried there in the Rural Cemetery. Legacy Belding's yellowthroat (''Geothlypis beldingi'' ) was named in his honor by Robert Ridgway. Belding's orange-throated whiptail ('' Aspidoscelis hyperythrus beldingi''), a subspecies of lizard, was named in his honour by Leonhard Stejneger. In addition to his work as a self-taught ornithologist, Belding made a contribution to Baja Ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subspecies
In Taxonomy (biology), biological classification, subspecies (: subspecies) is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (Morphology (biology), morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated as subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific name, infraspecific ranks, such as variety (botany), variety, may be named. In bacteriology and virology, under standard International Code of Nomenclature of Prokaryotes, bacterial nomenclature and virus clas ...

Gait
Gait is the pattern of Motion (physics), movement of the limb (anatomy), limbs of animals, including Gait (human), humans, during Animal locomotion, locomotion over a solid substrate. Most animals use a variety of gaits, selecting gait based on speed, terrain, the need to wikt:maneuver, maneuver, and energetic efficiency. Different animal species may use different gaits due to differences in anatomy that prevent use of certain gaits, or simply due to evolved innate preferences as a result of habitat differences. While various gaits are given specific names, the complexity of biological systems and interacting with the environment make these distinctions "fuzzy" at best. Gaits are typically classified according to footfall patterns, but recent studies often prefer definitions based on mechanics. The term typically does not refer to limb-based propulsion through fluid mediums such as water or air, but rather to propulsion across a solid substrate by generating reactive forces against ...

Cobalt Blue
Cobalt blue is a blue pigment made by sintering cobalt(II) oxide with aluminium(III) oxide (alumina) at 1200 °C. Chemically, cobalt blue pigment is cobalt(II) oxide-aluminium oxide, or cobalt(II) aluminate, CoAl2O4. Cobalt blue is lighter and less intense than the (iron-cyanide based) pigment Prussian blue. It is extremely stable, and has historically been used as a coloring agent in ceramics (especially Chinese porcelain), jewelry, and paint. Transparent glasses are tinted with the silica-based cobalt pigment "smalt". Historical uses and production Ores containing cobalt have been used since antiquity as pigments to give a blue color to porcelain and glass. Cobalt blue in impure forms had long been used in Chinese porcelain. In 1742, Swedish chemist Georg Brandt showed that the blue color was due to a previously unidentified metal, cobalt. The first recorded use of ''cobalt blue'' as a color name in English was in 1777. It was independently discovered as an alumina ...
