Plestiodon Egregius
''Plestiodon egregius'', the mole skink, is a species of small lizard endemic to the Southeastern United States. Taxonomy The species is subdivided into five subspecies, including the nominotypical subspecies: *Florida Keys mole skink, ''P. e. egregius'' Baird, 1859: occurs only on some of the Florida Keys. *Cedar Key mole skink, ''P. e. insularis'' (Mount, 1965): occurs only on three islands at Cedar Key. *Bluetail mole skink, ''P. e. lividus'' (Mount, 1965): occurs only in interior central Florida; shares its Florida Scrub habitat with the Sand Skink. *Peninsula mole skink, ''P. e. onocrepis'' Cope, 1871. *Northern mole skink, ''P. e. similis'' ( McConkey, 1957). The species was first described by Baird in 1859 as ''Plestiodon egregius''. In 1871, ''P. onocrepis'' was described by Cope. In 1875, the two species were reassigned to the genus ''Eumeces''. In 1935, two subspecies were defined, ''E. e. egregius'' and ''E. e. onocrepis'', and in 1957, ''E. e. similis'' was separa ...

Spencer Fullerton Baird
Spencer Fullerton Baird (; February 3, 1823 – August 19, 1887) was an American naturalist, ornithologist, ichthyologist, Herpetology, herpetologist, and museum curator. Baird was the first curator to be named at the Smithsonian Institution. He eventually served as assistant Secretary of the Smithsonian from 1850 to 1878, and as Secretary from 1878 until 1887. He was dedicated to expanding the natural history collections of the Smithsonian which he increased from 6,000 specimens in 1850 to over 2 million by the time of his death. He published over 1,000 works during his lifetime. Early life and education Spencer Fullerton Baird was born in Reading, Pennsylvania in 1823. His mother was a member of the prominent Philadelphia Biddle family; he was a nephew of Speaker of the Pennsylvania Senate Charles B. Penrose and a first cousin, once removed, of U.S. Senator Boies Penrose and his distinguished brothers, R. A. F. Penrose Jr., Richard, Spencer Penrose, Spencer, and Charles Bingham ...

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 ...

Plestiodon
''Plestiodon'' is a genus of lizards in the family Scincidae (skinks). The genus contains many species formerly classified under the genus ''Eumeces'', except those now placed in ''Mesoscincus''. They are secretive, agile animals with a cylindrical body covered with smooth, shiny scales. They are distributed from East Asia to throughout North America from southern Canada south to Mexico, including oceanic islands such as Bermuda. Defensive mechanism The conspicuous coloring of species of ''Plestiodon'' is a survival trait: it attracts a predator's attention to the tail of the animal, which will break off when grabbed. A skink thus often manages to escape and hide under some rock, log, or fallen leaves while the predator still contemplates the wildly thrashing severed tail. (This is an instance of what is called autotomy: voluntarily shedding a body part in order to escape, and later re generating the body part.) After the tail regenerates, it usually has the same color as the r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kilobyte
The kilobyte is a multiple of the unit byte for digital information. The International System of Units (SI) defines the prefix ''kilo'' as 1000 (103); per this definition, one kilobyte is 1000 bytes.International Standard IEC 80000-13 Quantities and Units – Part 13: Information science and technology, International Electrotechnical Commission (2008). The internationally recommended unit symbol for the kilobyte is kB. In some areas of information technology, particularly in reference to solid-state memory capacity, ''kilobyte'' instead typically refers to 1024 (210) bytes. This arises from the prevalence of sizes that are powers of two in modern digital memory architectures, coupled with the accident that 210 differs from 103 by less than 2.5%. A kibibyte is defined by Clause 4 of IEC 80000-13 as 1024 bytes. Definitions and usage Base 10 (1000 bytes) In the International System of Units (SI) the prefix ''kilo'' means 1000 (103); therefore, one kilobyte is 1000 bytes. The u ...

Federally Threatened Species
The Endangered Species Act of 1973 (ESA or "The Act"; 16 U.S.C. § 1531 et seq.) is the primary law in the United States for protecting imperiled species. Designed to protect critically imperiled species from extinction as a "consequence of economic growth and development untempered by adequate concern and conservation", the ESA was signed into law by President Richard Nixon on December 28, 1973. The Supreme Court of the United States described it as "the most comprehensive legislation for the preservation of endangered species enacted by any nation"."Tennessee Valley Authority v. Hill" 437 U.S. 153 (1978) Retrieved 24 November 2015. The purposes of the ESA are two-fold: to prevent extinction and to recover species to the point where the law's protections are not needed.

Cricket (insect)
Crickets are orthopteran insects which are related to bush crickets, and, more distantly, to grasshoppers. In older literature, such as Imms,Imms AD, rev. Richards OW & Davies RG (1970) ''A General Textbook of Entomology'' 9th Ed. Methuen 886 pp. "crickets" were placed at the family level (''i.e.'' Gryllidae), but contemporary authorities including Otte now place them in the superfamily Grylloidea. The word has been used in combination to describe more distantly related taxa in the suborder Ensifera, such as king crickets and mole crickets. Crickets have mainly cylindrically-shaped bodies, round heads, and long antennae. Behind the head is a smooth, robust pronotum. The abdomen ends in a pair of long cerci; females have a long, cylindrical ovipositor. Diagnostic features include legs with 3-segmented tarsi; as with many Orthoptera, the hind legs have enlarged femora, providing power for jumping. The front wings are adapted as tough, leathery elytra, and some crickets ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spider
Spiders ( order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had ...

Cockroach
Cockroaches (or roaches) are a paraphyletic group of insects belonging to Blattodea, containing all members of the group except termites. About 30 cockroach species out of 4,600 are associated with human habitats. Some species are well-known as pests. The cockroaches are an ancient group, with their ancestors, known as " roachoids", originating during the Carboniferous period, some 320 million years ago. Those early ancestors, however, lacked the internal ovipositors of modern roaches. Cockroaches are somewhat generalized insects lacking special adaptations (such as the sucking mouthparts of aphids and other true bugs); they have chewing mouthparts and are probably among the most primitive of living Neopteran insects. They are common and hardy insects capable of tolerating a wide range of climates, from Arctic cold to tropical heat. Tropical cockroaches are often much larger than temperate species. Modern cockroaches are not considered to be a monophyletic group, as it has be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sand Skink
The Florida sand skink (''Plestiodon reynoldsi'') is a species of lizard in the family Scincidae, the skinks. It is endemic to Florida in the United States. Taxonomy and etymology It was described as a new genus and new species by Leonhard Stejneger in 1910 and named in honor of a certain Mr. A.G. Reynolds of Gulfport, Florida, who had collected the holotype.Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. xiii + 296 pp. . (''Neoseps reynoldsi'', p. 220). Description A unique lizard adapted to an underground existence, the Florida sand skink measures in total length and is a gray to tan color. Its forelegs are tiny and bear only one toe each; its hindlegs are small and have two toes. The tail comprises about half of the animal's total length.
