Etheostomatinae
Etheosomatidae is a species rich subfamily of freshwater ray-finned fish, the members of which are commonly known as the darters. The subfamily is part of the family Percidae which also includes the perches, ruffes and pikeperches. The family is endemic to North America. It consists of 3-5 different genera and well over 200 species. Characteristics Species within the Etheostomatinae are all small fish, mostly less than in length and their bodies are slightly compressed or fusiform in shape. They have two pterygiophores between the first and second dorsal fins which do not have spines and a reduced swimbladder which may be completely lacking. The name darter becomes because these fish are seen to dart around in their habitat and these fish have benthic habits. They are sexually dimorphic and most species have males with bright colours and patterning, particularly when breeding and these colours and patterns are used to attract females and allow for recognition of species as ...

Nothonotus
''Nothonotus'' is a genus or subgenus 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 southeastern United States. First proposed as a sub-genus of '' Etheostoma'' in 1988, there is still debate regarding the appropriate taxonomic rank of ''Nothonotus'' in the literature . Darter species comprise more than 180 of the Percidae The Percidae are a family of ray-finned fish, part of the order Perciformes, which are found in fresh and brackish waters of the Northern Hemisphere. The majority are Nearctic, but there are also Palearctic species. The family contains more ... taxa.

Percina
''Percina'' is a genus of small freshwater ray-finned fish, classified within the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes and pikeperches from North America. Like the similar fishes in the genus '' Etheostoma'', they are some species called "darters". More specifically, the genus as a whole is known as roughbelly darters, while certain species of ''Percina'' with a pattern of vertical bars on the 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.

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.

Ammocrypta
''Ammocrypta'' is a genus of freshwater ray-finned fish, commonly known as the sand darters, which is classified in the subfamily Etheostomatinae, part of the family Percidae which also includes the perches, ruffes and pikeperches. The species in the genus occur in eastern North America in Canada and the continental United States. Characteristics ''Ammocrypta'' species are characterised by having rather elongate and slender bodies. Their bodies are translucent and there is only a single spine in the anal fin. They also have Spreitzer vertebrae, that is that the first three vertebrae of the backbone, counting from the head, have an open haemal arch which allows for the fish's kidney to expand. They have the habit of burying into the sand or gravel bed of streams, only their eyes being visible. The translucence of their bodies and their habit of burying themselves gives them some protection against predation. The shared morphological characteristics of ''Ammocrypta'' with its s ...

Crystallaria
''Crystallaria'' is a genus of freshwater ray-finned fish which is classified in the subfamily Etheostomatinae, commonly known as the darters, part of the family Percidae which also includes the perches, ruffes and pikeperches. They are found in the Mississippi River basin from Ohio to Minnesota and in southern Mississippi, northern Louisiana, and southeastern Oklahoma, and on the Gulf Slope of Escambia, Mobile Bay, and the Pearl River drainages. They have now been extirpated from Ohio, Kentucky, Indiana, and Illinois. Taxonomy ''Crystallaria'' is the sister taxon of the genus ''Ammocrypta'' and together these genera are the sister taxon of the clade consisting of the speciose genus ''Etheostoma'' and ''Nothonotus''. Some authorities regard ''Crystallaria'' as a subgenus of ''Ammocrypta''. Species Currently, two species in this genus are recognized: * '' Crystallaria asprella'' D. S. Jordan, 1878 (Crystal darter) * ''Crystallaria cincotta The diamond darter (''Crystallaria ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Etheostoma Blennioides
The greenside darter (''Etheostoma blennioides'') 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 inhabits swift riffles in the eastern United States and southern Ontario. Biology Greenside darters typically live for three to five years, grow to a maximum of 5.2 inches (132 mm) standard length and sexually mature at one to two years of age. Greenside darters are reproductively active from February to April in the Midwest and Southeastern United States. Spawning occurs over algae- or moss-covered rocks in deep, swift riffles that are guarded by males that vigorously defended against intruders. Females linger in pools below the riffle and move into a male's territory when ready to spawn. Eggs are viscous and stick together in small clumps on green algae (''Cladophora''), moss (''Fontinalis''), and riverweed (Podostemaceae). ''E. blennioides'' ...

Percidae
The Percidae are a family of ray-finned fish, part of the order Perciformes, which are found in fresh and brackish waters of the Northern Hemisphere. The majority are Nearctic, but there are also Palearctic species. The family contains more than 200 species in 11 genera. The perches, and their relatives are in this family; well-known species include the walleye, sauger, ruffe, and three species of perch. However, small fish known as darters are also a part of this family. Characteristics The family is characterised by having the dorsal fin split into two which are normally separated or have a narrow connection, although this is wider in the genus ''Zingel'', the front section contains the spines and the rear section contains the soft rays. The anal fin contains 1 or 2 spines, if there is a second spine it is typically weak. The pelvic fins are placed on the thorax and have a single spine and 5 soft rays. They also have skeletal synapomorphies. The maximum size attaine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 flows generally south for to the Mississippi River Delta in the Gulf of Mexico. With its many tributaries, the Mississippi's watershed drains all or parts of 32 U.S. states and two Canadian provinces between the Rocky and Appalachian mountains. The main stem is entirely within the United States; the total drainage basin is , of which only about one percent is in Canada. The Mississippi ranks as the thirteenth-largest river by discharge in the world. The river either borders or passes through the states of Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana. Native Americans have lived along the Mississippi River and its tributaries for thousands of years. Most were hunter-gathere ...

Frederic Ward Putnam
Frederic Ward Putnam (April 16, 1839 – August 14, 1915) was an American anthropologist and biologist. Biography Putnam was born and raised in Salem, Massachusetts, the son of Ebenezer (1797–1876) and Elizabeth (Appleton) Putnam. After leaving college, Ebenezer had for a short time engaged in fitting young men for college, but soon went into business in Cincinnati as a commission merchant, a line in which he was successful. Recalled to Salem by his father's death in 1826, Ebenezer married there and devoted himself to the study and cultivation of plants and fruits, and involved himself in the Democratic Party in his county. Although frequently offered office, Ebenezer never accepted, except to serve as alderman in the so-called “model-government” of Salem when that town was first chartered as a city, and as postmaster of Salem.''The Cyclopædia of American Biography'', 1918 Frederic's early studies were at private schools, and with his father at home. He became curator of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Constantine Samuel Rafinesque
Constantine Samuel Rafinesque-Schmaltz (; October 22, 1783September 18, 1840) was a French 19th-century polymath born near Constantinople in the Ottoman Empire and self-educated in France. He traveled as a young man in the United States, ultimately settling in Ohio in 1815, where he made notable contributions to botany, zoology, and the study of prehistoric earthworks in North America. He also contributed to the study of ancient Mesoamerican linguistics, in addition to work he had already completed in Europe. Rafinesque was an eccentric and erratic genius. He was an autodidact, who excelled in various fields of knowledge, as a zoologist, botanist, writer and polyglot. He wrote prolifically on such diverse topics as anthropology, biology, geology, and linguistics, but was honored in none of these fields during his lifetime. Indeed, he was an outcast in the American scientific community whose submissions were rejected automatically by leading journals. Among his theories were th ...

Charles Henry Gilbert
Charles Henry Gilbert (December 5, 1859 in Rockford, Illinois – April 20, 1928 in Palo Alto, California) was a pioneer ichthyologist and fishery biologist of particular significance to natural history of the western United States. He collected and studied fishes from Central America north to Alaska and described many new species. Later he became an expert on Pacific salmon and was a noted conservationist of the Pacific Northwest. He is considered by many as the intellectual founder of American fisheries biology. He was one of the 22 "pioneer professors" (founding faculty) of Stanford University. Early life and education Born in Rockford, Illinois, Gilbert spent his early years in Indianapolis, Indiana, where he came under the influence of his high school teacher, David Starr Jordan (1851‒1931). When Jordan became Professor of Natural History at Butler University in Indianapolis, Gilbert followed and received his B.A. degree in 1879. Jordan moved to Indiana Univer ...

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] |
