Hybopsis Winchelli
The clear chub (''Hybopsis winchelli'') is a species of freshwater fish in the carp family ( Cyprinidae). Description ''Hybopsis winchelli'' is a species of freshwater fish with terminal maxillary barbels at exist in various degrees of development. Some populations have well developed barbels while others have rudimentary barbels. Other populations have barbels that are nonexistent. Just as the barbel development is variable, so is the pigmentation of the fish. Most populations exhibit a dark band that runs laterally along the sides, opercle, snout and causal base of the fish. In most populations, the pigmentation intensifies at the causal base that forms an ill-defined, continuous causal spot. There may also be a predorsal stripe and a small dark spot on the dorsal fin. The scales themselves have a pigment concentration along the edges of the scales so that they give the fish a cross-hatched appearance. The sides below the lateral line are white, and the only melanophores are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Frédéric Girard
Charles Frédéric Girard (8 March 1822 – 29 January 1895) was a French biologist specializing in ichthyology and herpetology. Born in Mulhouse, France, he studied at the College of Neuchâtel, Switzerland, as a student of Louis Agassiz. In 1847, he accompanied Agassiz as his assistant to Harvard University. Three years later, Spencer Fullerton Baird called him to the Smithsonian Institution to work on its growing collection of North American reptiles, amphibians and fishes. He worked at the museum for the next ten years and published numerous papers, many in collaboration with Baird. In 1854, he was naturalized as a U.S. citizen. Besides his work at the Smithsonian, he managed to earn an M.D. from Georgetown University in Washington, D.C. in 1856. In 1859 he returned to France and was awarded the Cuvier Prize by the Institute of France for his work on the North American reptiles and fishes two years later. When the American Civil War broke out, he joined the Confederate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apalachicola River
The Apalachicola River is a river, approximately 160 mi (180 km) long in the state of Florida. The river's large watershed, known as the ACF River Basin, drains an area of approximately into the Gulf of Mexico. The distance to its farthest head waters in northeast Georgia is approximately 500 miles (800 km). Its name comes from the Apalachicola people, who used to live along the river. Description The river is formed on the state line between Florida and Georgia, near the town of Chattahoochee, Florida, approximately northeast of Panama City, by the confluence of the Flint and Chattahoochee rivers. The actual confluence is contained within the Lake Seminole reservoir formed by the Jim Woodruff Dam. It flows generally south through the forests of the Florida Panhandle, past Bristol. In northern Gulf County, it receives the Chipola River from the west. It flows into Apalachicola Bay, an inlet of the Gulf of Mexico, at Apalachicola, Florida. The lower of the riv ...

Fish Described In 1856
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 ...

Taxa Named By Charles Frédéric Girard
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alexander Winchell
Alexander Winchell (December 31, 1824, in North East, New York – February 19, 1891, in Ann Arbor, Michigan) was a United States geologist who contributed to this field mainly as an educator and a popular lecturer and author. His views on evolution aroused controversy among his contemporaries; today the racism of these views is more cause for comment. Biography Education Winchell graduated from the Wesleyan University of Middletown, Connecticut, in 1847. Early career He then taught at Pennington Male Seminary of New Jersey, Amenia Seminary of New York (where he had previously been a student), an academy in Newbern, Alabama, and the Mesopotamia Female Seminary of Eutaw, the last of which was founded by him. He became president of the Masonic University at Selma, Alabama, in 1853. He was elected as a member of the American Philosophical Society in 1865. Michigan In 1854 Winchell entered the service of the University of Michigan as professor of physics and civil enginee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flint River (Georgia)
The Flint River is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map, accessed April 15, 2011 river in the U.S. state of Georgia. The river drains of western Georgia, flowing south from the upper Piedmont region south of Atlanta to the wetlands of the Gulf Coastal Plain in the southwestern corner of the state. Along with the Apalachicola and the Chattahoochee rivers, it forms part of the ACF basin. In its upper course through the red hills of the Piedmont, it is considered especially scenic, flowing unimpeded for over . Historically, it was also called the Thronateeska River. Description The Flint River rises in west central Georgia in the city of East Point in southern Fulton County on the southern outskirts of the Atlanta metropolitan area as ground seepage. The exact start can be traced to the field located between Plant Street, Willingham Drive, Elm Street, and Vesta Avenue. It travels under the runways of the Hartsfi ...

Ocklockonee River
The Ochlockonee River ( ) is a fast running river, except where it has been dammed to form Lake Talquin in Florida, originating in Georgia and flowing for before terminating in Florida. Background The name is from the Hitchiti language words for yellow river. The Ochlockonee originates south of the town of Sylvester in Worth County in southwest Georgia and empties into Ochlockonee Bay and then Apalachee Bay in Florida. The river forms the western boundaries of Leon County and Wakulla County and eastern boundaries of Gadsden County, Liberty County, and Franklin County in Florida. It flows through the Red Hills, the Jackson Bluff Dam, Talquin State Forest, Lake Talquin State Park and the Apalachicola National Forest, and past Ochlockonee River State Park, where it is tidally influenced and a mixture of fresh, brackish, and salt water, on the way to its terminus in Ochlockonee Bay, which then empties into Apalachee Bay, with tidal influences extending upstream over from ...

Freshwater Fish
Freshwater fish are those that spend some or all of their lives in fresh water, such as rivers and lakes, with a salinity of less than 1.05%. These environments differ from marine conditions in many ways, especially the difference in levels of salinity. To survive fresh water, the fish need a range of physiology, physiological adaptations. 41.24% of all known species of fish are found in fresh water. This is primarily due to the rapid speciation that the scattered habitats make possible. When dealing with ponds and lakes, one might use the same basic models of speciation as when studying island biogeography. Physiology Freshwater fish differ physiologically from salt water fish in several respects. Their gills must be able to diffuse dissolved gases while keeping the salts in the body fluids inside. Their scales reduce water diffusion through the skin: freshwater fish that have lost too many scales will die. They also have well developed kidneys to reclaim salts from body flui ...
