Madtom
Madtoms are freshwater catfishes (order Siluriformes) of the genus ''Noturus'' of the family Ictaluridae. It is the most species-rich family of catfish in North America, native to the central and eastern United States, and adjacent parts of Canada. Their fin spines contain a mild venom with a sting comparable to that of a honey bee. Nearly half the species of madtom catfishes were described in a single comprehensive revision of the group. Morphology is very conserved in this genus; most of the species look very similar and telling them apart with the usual meristic and morphometric characters used to identify species is difficult. The more conspicuously variable attributes of these secretive fishes are features of pigmentation, which also are more difficult to quantify and often vary according to substrate and water quality. These species have small to tiny or fragmented ranges, and aspects of pigmentation are important diagnostic characters of each. Over one-quarter of the recog ...

Noturus Baileyi
The smoky madtom (''Noturus baileyi'') is a species of catfish. Little information exists about the smoky madtom, along with other members of the ''Noturus'' species, due to the high turbidity in which they spawn, preventing observation, as well as their nocturnal behaviors. Description The madtom is a small member of the family Ictaluridae, only reaching a maximum of 5 cm (2 in) long. It is olive brown on top with white to yellow below. Four saddles line the back of this species.Global Species. 2009-2011. Noturus baileyi.

Noturus Exilis
''Noturus exilis'', also called the slender madtom, is a species of the catfish family Ictaluridae. Ictaluridae includes bullheads, madtoms, channel catfish, and blue catfish. ''Noturus exilis'' is found in the central portion of the Mississippi River basin, but is most abundant in Ozarkian streams. Slender madtoms occur west of the Mississippi River in the Ozarks of Oklahoma, Arkansas, and Missouri north to southern Wisconsin and Minnesota. It also occurs east of the Mississippi River in the uplands of Alabama, Tennessee, and Kentucky in the Tennessee, Cumberland, and Green drainages. Nelson first described ''Noturus exilis'' in 1876.

Noturus Trautmani
The Scioto madtom (''Noturus trautmani'') was a species of fish in the family Ictaluridae. It is listed as extinct by the International Union for Conservation of Nature, which notes that it has likely been entirely or functionally extinct since 1957 given the lack of records since that year. This fish was endemic to Ohio in the United States. Only one population was ever known; it was located in Big Darby Creek, a tributary of the Scioto River. Eighteen specimens were collected, all at one riffle A riffle is a shallow landform in a flowing channel. Colloquially, it is a shallow place in a river where water flows quickly past rocks. However, in geology a riffle has specific characteristics. Topographic, sedimentary and hydraulic indica ... in this creek, an area called Trautman's Riffle. It has not been seen since 1957.

Noturus Fasciatus
''Noturus fasciatus'' (saddled madtom) is a rare freshwater fish native to the U.S. state of Tennessee. It was first described as a species separate from ''Noturus crypticus'' in 2005.Burr, M. Eisenhour, D. Grady, J. 2005. Two new species of Noturus (Siluriformes : Ictaluridae) from the Tennessee River drainage: Description, distribution, and conservation status. Copeia. 2005. 4: 783-802 It is restricted to the Duck River system and is also found in two minor tributaries on the lower section of the Tennessee River. This species dwells in small to medium-sized streams where they can be found under gravel, rubble, and slab rock.

Noturus Elegans
The elegant madtom (''Noturus elegans'') is a fish native to Tennessee, Alabama, and Kentucky, and is one of twenty-nine species of madtom. It prefers to live in small rivers and gravel-bottomed creeks. The average lifespan of the elegant madtom is two years. The elegant madtom is not listed on any federal or state conservation lists. However, scientists who have done surveys on the fish have recommended that it should be listed as threatened. Classification Until the 1990s and early 2000, ''Noturus crypticus'' and '' Noturus fasciatus'' were thought to be the same species as ''Noturus elegans''. However, they are now considered distinct species. The chucky madtom, ''N. crypticus'', is the only one of the three currently listed as severely threatened.Burr, B.M., And Walter W Dimmick. 1981.

Noturus Crypticus
The chucky madtom (''Noturus crypticus'') is a critically endangered freshwater fish endemic to the U.S. state of Tennessee Tennessee ( , ), officially the State of Tennessee, is a landlocked state in the Southeastern region of the United States. Tennessee is the 36th-largest by area and the 15th-most populous of the 50 states. It is bordered by Kentucky to th .... It has been observed in two streams in eastern Tennessee, Little Chucky Creek and Dunn Creek. The last observed specimen in Dunn Creek was collected in 1940 and the species is likely no longer present in that location. Because the species is endangered, and the number of known individuals is so low, there is no information regarding spawning conditions or diet. However, it is theorized that they may spawn in the early summer. Due to the dismal population size little is also known about the life history. The population is in decline most likely due to habitat degradation. The current management plan for the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward William Nelson
Edward William Nelson (May 8, 1855 – May 19, 1934) was an American naturalist and ethnologist. A collector of specimens and field naturalist of repute, he became a member of several expeditions to survey the fauna and flora. He was part of a team with Clinton Hart Merriam that took part in the Death Valley Expedition. He also explored the Yosemite Valley. A number of vertebrate species are named after him. Biography Nelson was born in Manchester, New Hampshire, on May 8, 1855, the first son of William and Martha () Nelson. Nelson and his brother then lived with his maternal grandparents in the Adirondacks when his father joined the Union Army and mother went to Baltimore as a nurse. Here he fell in love with the wilderness. Nelson moved to Chicago after his father was killed in the Civil War and his mother established a dressmaking business. In 1871, his large insect collection was lost in the Chicago Fire and the family was left homeless. This was the time that h ...

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] |
