Cumberland Slider
The Cumberland slider (''Trachemys scripta troostii)'', also called commonly the Cumberland turtle and Troost's turtle, is a subspecies of pond slider, a semiaquatic turtle in the family Emydidae. The subspecies is indigenous to the Southeastern United States. Etymology The subspecific name, ''troostii'', is in honor of Dutch-American naturalist Gerard Troost. Taxonomy ''T. s. troostii'', a subspecies of ''T. scripta'', was formerly placed in the genus ''Pseudemys''. The Cumberland slider occurs in a different geographic location from the yellow-bellied slider (''T. s. scripta''). Intergradation does not occur between these two subspecies. Description The carapace of ''T. s. troostii'' is olive brown with yellow markings. It has two rounded projections on the posterior edge of the shell, and is slightly keeled. The adult carapace is wrinkled and oval shaped. The plastron is hingeless and slightly smaller than the carapace. Each of the bottom sides of the marginals has a s ...

John Edwards Holbrook
John Edwards Holbrook (December 31, 1796 – September 8, 1871) was an American zoologist, herpetologist, physician, and naturalist, born in Beaufort, South Carolina, the son of Silas Holbrook, a teacher, and Mary Edwards. Although Holbrook's memoir, written by his medical partner, and his tombstone both give the date 1794 for his birth, this is incorrect. Holbrook received his A.B. degree from Brown University in 1815, and his M.D. from the University of Pennsylvania in 1818. In 1827, he married Harriott Pinckney Rutledge (1802–1863), granddaughter of John Rutledge and a member of the Middleton-Rutledge-Pinckney family. He provided the first comprehensive illustrated account of North American amphibians and reptiles in the two editions of his ''North American Herpetology; or, A Description of the Reptiles Inhabiting the United States''. The first edition in four volumes (1836–1840) is very rare because Holbrook attempted to destroy all copies in a bonfire in his backyard over ...

Turtle
Turtles are an order of reptiles known as Testudines, characterized by a special shell developed mainly from their ribs. Modern turtles are divided into two major groups, the Pleurodira (side necked turtles) and Cryptodira (hidden necked turtles), which differ in the way the head retracts. There are 360 living and recently extinct species of turtles, including land-dwelling tortoises and freshwater terrapins. They are found on most continents, some islands and, in the case of sea turtles, much of the ocean. Like other amniotes (reptiles, birds, and mammals) they breathe air and do not lay eggs underwater, although many species live in or around water. Turtle shells are made mostly of bone; the upper part is the domed carapace, while the underside is the flatter plastron or belly-plate. Its outer surface is covered in scales made of keratin, the material of hair, horns, and claws. The carapace bones develop from ribs that grow sideways and develop into broad flat plates th ...

David B
David Robert Jones (8 January 194710 January 2016), known professionally as David Bowie ( ), was an English singer-songwriter and actor. A leading figure in the music industry, he is regarded as one of the most influential musicians of the 20th century. Bowie was acclaimed by critics and musicians, particularly for his innovative work during the 1970s. His career was marked by reinvention and visual presentation, and his music and stagecraft had a significant impact on popular music. Bowie developed an interest in music from an early age. He studied art, music and design before embarking on a professional career as a musician in 1963. "Space Oddity", released in 1969, was his first top-five entry on the UK Singles Chart. After a period of experimentation, he re-emerged in 1972 during the glam rock era with his flamboyant and androgynous alter ego Ziggy Stardust (character), Ziggy Stardust. The character was spearheaded by the success of Bowie's single "Starman (song), Starma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tennessee River
The Tennessee River is the largest tributary of the Ohio River. It is approximately long and is located in the southeastern United States in the Tennessee Valley. The river was once popularly known as the Cherokee River, among other names, as the Cherokee people had their homelands along its banks, especially in what are now East Tennessee and northern Alabama. Additionally, its tributary, the Little Tennessee River, flows into it from Western North Carolina and northeastern Georgia, where the river also was bordered by numerous Cherokee towns. Its current name is derived from the Cherokee town, ''Tanasi'', which was located on the Tennessee side of the Appalachian Mountains. Course The Tennessee River is formed at the confluence of the Holston and French Broad rivers in present-day Knoxville, Tennessee. From Knoxville, it flows southwest through East Tennessee into Chattanooga before crossing into Alabama. It travels through the Huntsville and Decatur area before rea ...

Sunning (behaviour)
Sunning or basking, sometimes also known as sunbathing, is a thermoregulatory or comfort behaviour used by animals, especially birds, reptiles, and insects, to help raise their body temperature, reduce the energy needed for temperature maintenance or to provide comfort. They may also have additional functions of ridding animals of ectoparasites, bacteria, or excess moisture. Birds Birds adopt special postures when sunning, these may include spreading out their feathers, flattening their body on soil, showing either their upper parts to the sun or facing the sun. Some authors separate the behaviours into sun-basking and sun-exposure - the former term used when the behaviour is strictly thermoregulatory in function while the latter term may be more appropriate if the behaviour serves functions other than raising body temperature. In some species, the sunbathing posture is adopted in very hot weather and the birds sometimes stay in close contact with hot soil. Birds may fluff up th ...

Carapace
A carapace is a Dorsum (biology), dorsal (upper) section of the exoskeleton or shell in a number of animal groups, including arthropods, such as crustaceans and arachnids, as well as vertebrates, such as turtles and tortoises. In turtles and tortoises, the underside is called the plastron. Crustaceans In crustaceans, the carapace functions as a protective cover over the cephalothorax (i.e., the fused head and thorax, as distinct from the abdomen behind). Where it projects forward beyond the eyes, this projection is called a rostrum (anatomy), rostrum. The carapace is Calcification, calcified to varying degrees in different crustaceans. Zooplankton within the phylum Crustacea also have a carapace. These include Cladocera, ostracods, and Isopoda, isopods, but isopods only have a developed "cephalic shield" carapace covering the head. Arachnids In arachnids, the carapace is formed by the fusion of prosomal tergites into a single Plate (animal anatomy), plate which carries the e ...

Yellow-bellied Slider
The yellow-bellied slider (''Trachemys scripta scripta'') is a land and water turtle belonging to the family Emydidae. This subspecies of pond slider is native to the southeastern United States, specifically from Florida to southeastern Virginia, and is the most common turtle species in its range. It is found in a wide variety of habitats, including slow-moving rivers, floodplain swamps, marshes, seasonal wetlands, and permanent ponds. Yellow-bellied sliders are popular as pets. Description Adult male yellow-bellied sliders typically reach in length; females range from . The carapace (upper shell) is typically brown and black, often with yellow stripes. The skin is olive green with prominent patches of yellow down the neck and legs. As the name implies, the plastron (bottom shell) is mostly yellow with black spots along the edges. Adults tend to grow darker as they age. Yellow-bellied sliders are often confused with eastern river cooters, who also have yellow stripes on the ne ...

Pseudemys
''Pseudemys'' is a genus of large, herbivorous, freshwater turtles of the eastern United States and adjacent northeast Mexico. They are often referred to as cooters, which stems from ''kuta'', the word for turtle in the Bambara and Malinké languages, brought to America by enslaved people from Africa. Etymology The generic name ''Pseudemys'' is derived from the Greek words, ''pseudes'' meaning false or misleading, and ''emydos'' a freshwater turtle, implying a resemblance to, but not included in the genus ''Emys''.Seidel, Michael and Carl H. Ernst. 1996. Pseudemys'' Catalogue of American Amphibians and Reptile. Society for the Study of Amphibians and Reptiles. 625: 1-7 pp. The trivial names, or specific epithets, of five of the species are toponyms, named for places where the species were first discovered including, the Florida peninsular (''P. peninsularis''),Seidel, Michael and Carl H.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Gerard Troost
Gerardus Troost (March 5, 1776 – August 14, 1850) was a Dutch-American medical doctor, naturalist, mineralogist, and founding member and first president of the Philadelphia Academy of Natural Sciences.; archive.org copie Biography Troost was born in Den Bosch, Netherlands, to Anna Cornelia (Van Heeck) and Everardus Josephus Troost. He received the degree of Doctor of Medicine from the University of Leyden, and of Master in Pharmacy, in 1801, from the University of Amsterdam. After a brief practice at Amsterdam and the Hague, he was enlisted in the army as a private soldier, and then as an officer of the first class in the medical department. During these periods of service, he was wounded in the thigh and in the head. In 1807 Troost went to Paris under the patronage of Louis Napoleon, King of Holland. There he studied at the School of Mines with renowned mineralogist René Just Haüy. While in Paris, he translated into the Dutch language one of the earlier works of Alexander ...

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (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 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 ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
