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 ...

Tennessee River
The Tennessee River is the largest tributary of the Ohio River. It is approximately long and is located in the southeastern United States in the Tennessee Valley. The river was once popularly known as the Cherokee River, among other names, as the Cherokee people had their homelands along its banks, especially in what are now East Tennessee and northern Alabama. Additionally, its tributary, the Little Tennessee River, flows into it from Western North Carolina and northeastern Georgia, where the river also was bordered by numerous Cherokee towns. Its current name is derived from the Cherokee town, ''Tanasi'', which was located on the Tennessee side of the Appalachian Mountains. Course The Tennessee River is formed at the confluence of the Holston and French Broad rivers in present-day Knoxville, Tennessee. From Knoxville, it flows southwest through East Tennessee into Chattanooga before crossing into Alabama. It travels through the Huntsville and Decatur area before rea ...

Shoal Creek (Tennessee River)
Shoal Creek (originally called the Sycamore River) is a river from its east point or from the north point on the Little Shoal Creek north of Lawrenceburg, Tennessee. The stream rises in northern Lawrence County, Tennessee, and enters the Tennessee River in Lauderdale County, Alabama, where its lower reaches are impounded in the backwater of Wilson Dam. Historically, Shoal Creek (Sycamore River) was an important source of water power for the cotton industry in Lawrence County. Among the early users of the stream's water power was David Crockett, who settled near the creek bank in 1817 and started a powder mill, grist mill and distillery. After these operations were destroyed by a flood in September 1821, Crockett left the area and moved to West Tennessee. The Crockett-Shoals region of Tennessee, including Lawrence County and surrounding areas, is named for Shoal Creek and this famous frontiersman who played an active role in establishing Lawrence County and Lawrenceburg. This hi ...

Barren Fork (Collins River)
The Barren Fork is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map, accessed June 8, 2011 tributary of the Collins River in the U.S. state of Tennessee. Via the Collins River, the Caney Fork, and the Cumberland and Ohio rivers, it is part of the Mississippi River watershed. The Barren Fork rises in western Warren County, Tennessee. It is formed from the confluence of its north and south prongs, which join near the tiny community of Trousdale. Its component streams and their tributaries drain much of the eastern portions of Cannon County and Coffee County. The stream flows generally from west to east until it reaches the town of McMinnville, county seat of Warren County. From there it turns in a more northeasterly direction. From this point it is less than 5 linear miles (8 km) to the mouth of the Barren Fork into the Collins River, but considerably longer by the meandering course taken by the stream in its lower rea ...

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. Forbes, 1878) (mud darter) * '' Etheostoma atripinne'' ( D. S. Jordan, 1877) (Cumberland snubnose darter) * '' Etheostoma australe'' D. S. Jordan, 1889 (Conchos darter) * '' Etheostoma autumnale'' Mayden, 2010 (autumn darter) * '' E ...

Fish Described In 1878
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Most f ...
