Percina Antesella
The amber darter (''Percina antesella'') is a small, endangered species of freshwater ray-finned fish, a darter from the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes and pikeperches. It is native to the Conasauga River and Etowah River in Georgia and Tennessee in the United States. It typically inhabits riffle areas over gravel and sand bottoms, hiding in aquatic vegetation when present. It feeds on small invertebrates and probably breeds between late fall and early spring. It is an uncommon fish with a small range and the International Union for Conservation of Nature has classified its conservation status as being "endangered". Description The amber darter is typically less than in length and has a slender body. It has dark saddle-like markings on its golden brown upper body while the belly is a yellow-to-cream color. Breeding males have blue throats. Ecology While there is little data available about the breeding habits of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Etowah River
The Etowah River is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map, accessed April 27, 2011 waterway that rises northwest of Dahlonega, Georgia, Dahlonega, Georgia (U.S. state), Georgia, north of Atlanta. On Matthew Carey's 1795 map the river was labeled "High Town River". On later maps, such as the 1839 Cass County map (Cass being the original name for Bartow County), it was referred to as "Hightower River", a name that was used in most early Cherokee records. The large Amicalola Creek (which flows over Amicalola Falls) is a primary tributary near the beginning of the river. The Etowah then flows west-southwest through Canton, Georgia, and soon forms Lake Allatoona. From the dam at the lake, it passes Cartersville, Georgia, Cartersville and the Etowah Indian Mounds archaeological site. It then flows to Rome, Georgia, where it meets the Oostanaula River and forms the Coosa River at their confluence. The river is the north ...

Freshwater Fish Of The Southeastern United States
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. The term excludes seawater and brackish water, but it does include non-salty mineral-rich waters, such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of vascular plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh water is the water resource that is of the most and immediate use to humans. Fresh water is not always ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

More specifically, the genus as a whole is known as roughbelly darters, while certain species of ''Percina'' displaying vertical bars on their flanks are called logperches. Species There are currently 49 recognized species in this genus: * '' Percina antesella'' J. D. Williams & Etnier, 1978 (Amber darter) * '' Percina apristis'' C. L.

Gastropods
Gastropods (), commonly known as slugs and snails, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, freshwater, and from the land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, land snails and slugs. The class Gastropoda is a diverse and highly successful class of mollusks within the phylum Mollusca. It contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. , 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,00 ...

Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, invasive species, and climate change. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partners ...

David A
David (; , "beloved one") was a king of ancient Israel and Judah and the third king of the United Monarchy, according to the Hebrew Bible and Old Testament. The Tel Dan stele, an Aramaic-inscribed stone erected by a king of Aram-Damascus in the late 9th/early 8th centuries BCE to commemorate a victory over two enemy kings, contains the phrase (), which is translated as " House of David" by most scholars. The Mesha Stele, erected by King Mesha of Moab in the 9th century BCE, may also refer to the "House of David", although this is disputed. According to Jewish works such as the '' Seder Olam Rabbah'', '' Seder Olam Zutta'', and '' Sefer ha-Qabbalah'' (all written over a thousand years later), David ascended the throne as the king of Judah in 885 BCE. Apart from this, all that is known of David comes from biblical literature, the historicity of which has been extensively challenged,Writing and Rewriting the Story of Solomon in Ancient Israel; by Isaac Kalimi; page 3 ...

Sander (fish)
''Sander'' (formerly known as ''Stizostedion'') is a genus of predatory ray-finned fish in the Family (biology), family Percidae, which also includes the perches, Gymnocephalus, ruffes, and Darter (fish), darters. They are also known as "pike-perch" because of their resemblance to fish in the unrelated Esocidae (pike) family.

The earliest known fossils of this genus are partial jaw and vertebrae elements from the middle Miocene (Barstovian)-aged Wood Mountain Formation of Saskatchewan, Canada. Characteristics ''Sander'' species have elongated and laterally compressed bodies and they range in fish measurement, total length from in the Volga pikeperch (''S. volgensis'') to in the zander (''S. lucioperca''). The species within the genus share canine-like teeth that are at their largest in the zander, and although they are not present i ...
