Eurycea Quadridigitata
The southeastern dwarf salamander (''Eurycea quadridigitata''), formerly known as the dwarf salamander, is a species of salamander native to the southern United States, ranging primarily from southern North Carolina south to northern Florida, with some populations from southwestern Alabama to eastern Louisiana. Some sources refer to it as the four-fingered manculus, dwarf four-toed salamander, or the Florida dwarf salamander. Taxonomy A review of ''E. quadridigitata'' published in 2017 identified five cryptic species within ''E. quadridigitata'' based on molecular evidence.Wray, K. P., D. B. Means, and S. J.

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 ...

Eurycea Sphagnicola
The bog dwarf salamander (''Eurycea sphagnicola'') is a species of salamander endemic to the southern United States. Taxonomy It was previously thought to be a population of the southeastern dwarf salamander (''E. quadridigitata'') but a 2017 study found it to be a distinct species based on genetic evidence, and described it as ''E. sphagnicola''. It is unlikely that any previous studies had analyzed populations of this species. It is the most divergent of the eastern species in the dwarf salamander complex, having diverged from the clade containing '' E. quadridigitata'', '' E. hillisi'', and '' E. chamberlaini'' during the late Oligocene to mid-Miocene, about 23-15 million years ago. Distribution It is found only in a small portion of the Gulf Coast of the United States, being found in the western Florida Panhandle and southern Alabama and Mississippi. It is likely the most geographically restricted of all species in the dwarf salamander complex. Habitat It is notable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of The United States
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Egg (biology)
An egg is an organic vessel grown by an animal to carry a possibly fertilized egg cell (a zygote) and to incubate from it an embryo within the egg until the embryo has become an animal fetus that can survive on its own, at which point the animal hatches. Most arthropods such as insects, vertebrates (excluding live-bearing mammals), and mollusks lay eggs, although some, such as scorpions, do not. Reptile eggs, bird eggs, and monotreme eggs are laid out of water and are surrounded by a protective shell, either flexible or inflexible. Eggs laid on land or in nests are usually kept within a warm and favorable temperature range while the embryo grows. When the embryo is adequately developed it hatches, i.e., breaks out of the egg's shell. Some embryos have a temporary egg tooth they use to crack, pip, or break the eggshell or covering. The largest recorded egg is from a whale shark and was in size. Whale shark eggs typically hatch within the mother. At and up to , the o ...

Nocturnal Animal
Nocturnality is an animal behavior characterized by being active during the night and sleeping during the day. The common adjective is "nocturnal", versus diurnal meaning the opposite. Nocturnal creatures generally have highly developed senses of hearing, smell, and specially adapted eyesight. Some animals, such as cats and ferrets, have eyes that can adapt to both low-level and bright day levels of illumination (see metaturnal). Others, such as bushbabies and (some) bats, can function only at night. Many nocturnal creatures including tarsiers and some owls have large eyes in comparison with their body size to compensate for the lower light levels at night. More specifically, they have been found to have a larger cornea relative to their eye size than diurnal creatures to increase their : in the low-light conditions. Nocturnality helps wasps, such as ''Apoica flavissima'', avoid hunting in intense sunlight. Diurnal animals, including squirrels and songbirds, are active duri ...

Sensu Stricto
''Sensu'' is a Latin word meaning "in the sense of". It is used in a number of fields including biology, geology, linguistics, semiotics, and law. Commonly it refers to how strictly or loosely an expression is used in describing any particular concept, but it also appears in expressions that indicate the convention or context of the usage. Common qualifiers ''Sensu'' is the ablative case of the noun ''sensus'', here meaning "sense". It is often accompanied by an adjective (in the same case). Three such phrases are: *''sensu stricto'' – "in the strict sense", abbreviation ''s.s.'' or ''s.str.''; *''sensu lato'' – "in the broad sense", abbreviation ''s.l.''; *''sensu amplo'' – "in a relaxed, generous (or 'ample') sense", a similar meaning to ''sensu lato''. Søren Kierkegaard uses the phrase ''sensu eminenti'' to mean "in the pre-eminent r most important or significantsense". When appropriate, comparative and superlative adjectives may also be used to convey the meaning o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eurycea Paludicola
The western dwarf salamander (''Eurycea paludicola'') is species of salamander native to the southern United States. Taxonomy It was described in 1947 but later synonymized with the southeastern dwarf salamander (''Eurycea quadridigitata''). However, a 2017 study used . In addition, genetic studies indicate that it may be more closely related to the radiation of neotenic '' Eurycea'' of the Edwards Plateau in Texas than to the rest of the ''E. quadridigitata'' complex. Distribution It ranges from southern Mississippi east through Louisiana to eastern Texas Texas (, ; Spanish language, Spanish: ''Texas'', ''Tejas'') is a state in the South Central United States, South Central region of the United States.

Eurycea Hillisi
Hillis's dwarf salamander (''Eurycea hillisi'') is a species of salamander endemic to the southern United States. Taxonomy It was previously thought to be a population of the southeastern dwarf salamander (''E. quadridigitata'') but a 2017 study found it to be a distinct species based on genetic evidence, and described it as ''E. hillisi''. It is named in honor of American evolutionary biologist David Hillis. It is unlikely that any previous studies had analyzed populations of this species. Distribution It is found throughout the southern half of Alabama outside of the Mobile Bay region, and ranges east into mid-central Georgia and south to the central Florida Panhandle The Florida Panhandle (also West Florida and Northwest Florida) is the northwestern part of the U.S. state of Florida; it is a Salient (geography), salient roughly long and wide, lying between Alabama on the north and the west, Georgia (U. ....

Chamberlain's Dwarf Salamander
Chamberlain's dwarf salamander (''Eurycea chamberlaini'') is a species of salamander in the family Plethodontidae, endemic to the United States. Its natural habitats are temperate forests, rivers, and freshwater marshes. It is only found in the states of North Carolina and South Carolina. It was previously thought to be a color morph of the southeastern dwarf salamander (''Eurycea quadridigitata''), but was described in 2003 as a distinct species based on distinct morphology and behavior. A 2017 study reaffirmed it as being a distinct species. It was named after Edward Burnham Chamberlain, a former curator of the Vertebrate Zoology department at the Charleston Museum The Charleston Museum is a museum located in the Wraggborough neighborhood in Charleston, South Carolina. It is one of the oldest museums in the United States. Its highly regarded collection includes historic artifacts, natural history, decora ....

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 ...

Louisiana
Louisiana , group=pronunciation (French: ''La Louisiane'') is a state in the Deep South and South Central regions of the United States. It is the 20th-smallest by area and the 25th most populous of the 50 U.S. states. Louisiana is bordered by the state of Texas to the west, Arkansas to the north, Mississippi to the east, and the Gulf of Mexico to the south. A large part of its eastern boundary is demarcated by the Mississippi River. Louisiana is the only U.S. state with political subdivisions termed parishes, which are equivalent to counties, making it one of only two U.S. states not subdivided into counties (the other being Alaska and its boroughs). The state's capital is Baton Rouge, and its largest city is New Orleans, with a population of roughly 383,000 people. Some Louisiana urban environments have a multicultural, multilingual heritage, being so strongly influenced by a mixture of 18th century Louisiana French, Dominican Creole, Spanish, French Canadian, Acadi ...
