Savannah Slimy Salamander
The Savannah slimy salamander (''Plethodon savannah'') is a species of salamander in the family Plethodontidae. It is endemic to the state of Georgia in the United States, where it is restricted to the Atlantic coastal plain in Burke, Jefferson, and Richmond counties. This distribution reaches its eastern limit at the Savannah River. Its natural habitat is bottomland hardwood forest The bottomland hardwood forest is a type of deciduous and evergreen hardwood forest found in broad lowland floodplains along large rivers and lakes in the United States and elsewhere. They are occasionally flooded, which builds up the alluvial soi .... Population analysis indicates a precipitous decline in the population of this species, and it is becoming extirpated in many areas due to development; for example, the habitat at the type locality of this species was partially destroyed by a housing development.

Richmond County, Georgia
Richmond County is a county located in the U.S. state of Georgia. As of the 2010 census, the population was 200,549. It is one of the original counties of Georgia, created February 5, 1777. Following an election in 1995, the city of Augusta (the county seat) consolidated governments with Richmond County. The consolidated entity is known as Augusta-Richmond County, or simply Augusta. Exempt are the cities of Hephzibah and Blythe, in southern Richmond County, which voted to remain separate. Richmond County is included in the Augusta-Richmond County, GA- SC Metropolitan Statistical Area. History The county is named for Charles Lennox, 3rd Duke of Richmond, a British politician and office-holder sympathetic to the cause of the American colonies. Richmond was also a first cousin to King George III. Richmond County was established in 1777 by the first Constitution of the (newly independent) State of Georgia. As such, it is one of the original counties of the state. It was formed o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plethodon
''Plethodon'' is a genus of salamanders in the family Plethodontidae. They are also known as woodland salamanders or, more rarely, slimy salamanders. All members of the genus are endemic to North America (Canada and USA). They have no aquatic larval stage. In some species, such as ''Plethodon cinereus'', the red-backed salamander, eggs are laid underneath a stone or log. Young hatch in the adult form. Members of ''Plethodon'' primarily eat small invertebrates. The earliest known fossils of this genus are from the Hemphillian of Tennessee in the United States. Species There are 56 species in the genus ''Plethodon''. Listed in alphabetical order of specific name: ''Nota bene'': A binomial authority In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, bot ... in parentheses indicates that th ...

Endemic Amphibians 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] |
Type Locality (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost a ...

Local Extinction
Local extinction, also known as extirpation, refers to a species (or other taxon) of plant or animal that ceases to exist in a chosen geographic area of study, though it still exists elsewhere. Local extinctions are contrasted with global extinctions. Local extinctions mark a change in the ecology of an area. In recent times, local extinction has sometimes been followed by a replacement of the species taken from other locations; wolf reintroduction is an example of this. The term "local extinction" is highly vernacular. The more proper biological term is ''extirpation''. Discussion Glaciation can lead to local extinction. This was the case during the Pleistocene glaciation event in North America. During this period, most of the native North American species of earthworm were killed in places covered by glaciation. This left them open for colonization by European earthworms brought over in soil from Europe. Species naturally become extirpated from islands over time. The number ...

Bottomland Hardwood Forest
The bottomland hardwood forest is a type of deciduous and evergreen hardwood forest found in broad lowland floodplains along large rivers and lakes in the United States and elsewhere. They are occasionally flooded, which builds up the alluvial soils required for the gum, oak and bald cypress trees that typically grow in this type of biome. The trees often develop unique characteristics to allow submergence, including cypress knees and fluted trunks, but can not survive continuous flooding. Typical examples of this forest type are found throughout the Gulf Coast states, and along the Mississippi River The Mississippi River is the second-longest river and chief river of the second-largest drainage system in North America, second only to the Hudson Bay drainage system. From its traditional source of Lake Itasca in northern Minnesota, it fl ... in the United States.

Savannah River
The Savannah River is a major river in the southeastern United States, forming most of the border between the states of South Carolina and Georgia. Two tributaries of the Savannah, the Tugaloo River and the Chattooga River, form the northernmost part of the border. The Savannah River drainage basin extends into the southeastern side of the Appalachian Mountains just inside North Carolina, bounded by the Eastern Continental Divide. The river is around long.U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map, accessed April 26, 2011 The Savannah was formed by the confluence of the Tugaloo River and the Seneca River. Today this confluence is submerged beneath Lake Hartwell. The Tallulah Gorge is located on the Tallulah River, a tributary of the Tugaloo River that forms the northwest branch of the Savannah River.

Salamander
Salamanders are a group of amphibians typically characterized by their lizard-like appearance, with slender bodies, blunt snouts, short limbs projecting at right angles to the body, and the presence of a tail in both larvae and adults. All ten extant salamander families are grouped together under the order Urodela. Salamander diversity is highest in eastern North America, especially in the Appalachian Mountains; most species are found in the Holarctic realm, with some species present in the Neotropical realm. Salamanders rarely have more than four toes on their front legs and five on their rear legs, but some species have fewer digits and others lack hind limbs. Their permeable skin usually makes them reliant on habitats in or near water or other cool, damp places. Some salamander species are fully aquatic throughout their lives, some take to the water intermittently, and others are entirely terrestrial as adults. This group of amphibians is capable of regenerating lost lim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burke County, Georgia

Atlantic Coastal Plain
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth#Surface, Earth's surface and about 29% of its water surface area. It is known to separate the "Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of Earth, the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North America, North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8th paralle ...
