Speckled Darter
The speckled darter (''Etheostoma stigmaeum'') is a 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 endemic to the central and southeastern United States. It occurs in the Mississippi River basin and through the Gulf Coast drainages. It is also found in the Clinch River and the Powell River. This species inhabits rocky or sandy pools in flowing waters up to the size of medium rivers with fast currents. It can reach a length of TL though most only reach about . In 2012, studies found five distinct species that were formerly included in ''E. stigmaeum''. In a paper published in the ''Bulletin of the Alabama Museum of Natural History'', Mayden and Layman described five new species, all named after former U S presidents and one vice president, based on their "leadership in conservation policies": * ''Etheostoma teddyroosevelt'' (highland dar ...

David Starr Jordan
David Starr Jordan (January 19, 1851 – September 19, 1931) was the founding president of Stanford University, serving from 1891 to 1913. He was an ichthyologist during his research career. Prior to serving as president of Stanford University, he had served as president of Indiana University from 1884 to 1891. Starr was also a strong supporter of eugenics, and his published views expressed a fear of "race-degeneration" and asserted that cattle and human beings are "governed by the same laws of selection". He was an antimilitarist since he believed that war killed off the best members of the gene pool, and he initially opposed American involvement in World War I. Early life and career Jordan was born in Gainesville, New York, and grew up on a farm in upstate New York. His parents made the unorthodox decision to educate him at a local girls' high school. His middle name, Starr, does not appear in early census records, and was apparently self-selected; he had begun using ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clinch River
The Clinch River is a river that flows southwest for more than through the Great Appalachian Valley in the U.S. states of Virginia and Tennessee, gathering various tributaries, including the Powell River, before joining the Tennessee River in Kingston, Tennessee. Course The Clinch River is dammed twice: by Norris Dam, the first dam built by the Tennessee Valley Authority (TVA); and by the Melton Hill Dam, the only TVA dam with a navigation lock that is not located on the main channel of the Tennessee River. An important tributary of the Clinch River is the Powell River. The Clinch and Powell River drainage basins are separated by Powell Mountain. Tributaries entering the Clinch River below Norris Dam but above Melton Hill Dam include Coal Creek, Hinds Creek, Bull Run Creek, and Beaver Creek. Poplar Creek enters the river below the Melton Hill Dam. History A peninsula located at the mouth of the Clinch River, called Southwest Point, was the site of an early frontier fort ...

Etheostoma
''Etheostoma'' is a genus of small freshwater fish in the family Percidae native to North America. Most are restricted to the United States, but species are also found in Canada and Mexico. They are commonly known as darters, although the term "darter" is shared by several other genera. Many can produce alarm pheromones that serve to warn nearby fish in case of an attack.Smith, R.J.F. (1992): Alarm signals in fishes. ''Reviews in Fish Biology and Fisheries, 2 (1): 33-63.'' Species The 157 recognized species in this genus are: * ''Etheostoma acuticeps'' R. M. Bailey, 1959 (sharphead darter) * ''Etheostoma akatulo'' Layman & Mayden, 2009 (bluemask darter) * '' Etheostoma artesiae'' ( O. P. Hay, 1881) (redspot darter) * '' Etheostoma asprigene'' ( S. A.

Pensacola Bay
Pensacola Bay is a bay located in the northwestern part of Florida, United States, known as the Florida Panhandle. The bay, an inlet of the Gulf of Mexico, is located in Escambia County and Santa Rosa County, adjacent to the city of Pensacola, Florida, and is about 13 miles (21 km) long and 2.5 miles (4 km) wide. The Pensacola Bay estuarine system including Escambia Bay, Pensacola Bay, Blackwater Bay, East Bay, and Santa Rosa Sound, and four rivers—the Escambia,’ Blackwater,’ Yellow and East Rivers is 144 square miles, and it is the fourth largest estuarine system in Florida. Pensacola Bay is formed and protected by Fairpoint Peninsula and the barrier island of Santa Rosa. The Pensacola Bay Bridge crosses the bay, connecting Pensacola to Gulf Breeze on the western end of the peninsula. The Gulf Islands National Seashore includes Santa Rosa Island, and encloses part of the bay. The Gulf Intracoastal Waterway runs through a section of the bay. Pensacola Bay le ...

Sabine River (Texas–Louisiana)
The Sabine River () is a long riverU.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed June 20, 2011 in the Southern U.S. states of Texas and Louisiana, From the 32nd parallel north and downstream, it serves as part of the boundary between the two states and empties into Sabine Lake, an estuary of the Gulf of Mexico. Over the first half of the 19th century, the river formed part of the Spanish–American, Mexican–American, and Texan–American international boundaries. The upper reaches of the river flow through the prairie country of northeast Texas. Along much of its lower reaches, it flows through pine forests along the Texas–Louisiana border, and eventually the bayou country near the Gulf Coast. The river drains an area of , of which are in Texas and in Louisiana. It flows through an area of abundant rainfall and discharges the largest volume of any river in Texas.

Etheostoma Obama
''Etheostoma obama'', the spangled darter, is a 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 endemic to the eastern United States where it is only known to occur in the Duck River and the Buffalo River, both in Tennessee. Discovery and naming Steven Layman of Geosyntec Consultants and Rick Mayden of Saint Louis University studied the freshwater darters, most of which are native to Alabama and Tennessee in the United States. While they were studying color variation of ''Etheostoma stigmaeum'', the speckled darter, Layman and Mayden discovered that there were populations with enough variation that they should be described as unique species. This species was one of five distinct species of fish that were named after former U.S. presidents and a vice-president, based on their leadership in conservation. ''E. obama'' was named after Barack Obama, for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fish Measurement
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. Overall length * Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. Simply put, this measurement excludes the length of the caudal (tail) fin. * Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes (lampreys), and (usually) Elasmobranchii (sharks and rays), as well as some other fishes. Total length meas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Powell River (Tennessee River)
The Powell River is a 195-mile-long river in the United States that rises in Southwest Virginia and flows southwest into East Tennessee. The South Fork of the river rises in rural Wise County, Virginia, near the Laurel Grove community northwest of Norton and flows for several miles before the confluence with Roaring Fork in the Kent Junction community. From Kent Junction the river flows until it meets the North Fork of the River near Woodway, Virginia. The North Folk originates near Keokee, Virginia. The river flows past Big Stone Gap, Virginia and then runs nearly the entire length of Lee County, Virginia. It drains approximately 954 square miles (2,471 km2) in both Virginia and Tennessee before reaching its confluence with the Clinch River in the Norris Lake reservoir at the site of the town of Grantsboro. The Powell River was named for Ambrose Powell who accompanied the exploration party of Dr. Thomas Walker in the mid-18th century. Legend has it that his name app ...
