Edward Drinker Cope
Edward Drinker Cope (July 28, 1840 – April 12, 1897) was an American zoologist, paleontologist, comparative anatomist, herpetologist, and ichthyologist. Born to a wealthy Quaker family, Cope distinguished himself as a child prodigy interested in science; he published his first scientific paper at the age of 19. Though his father tried to raise Cope as a gentleman farmer, he eventually acquiesced to his son's scientific aspirations. Cope married his cousin and had one child; the family moved from Philadelphia to Haddonfield, New Jersey, although Cope would maintain a residence and museum in Philadelphia in his later years. Cope had little formal scientific training, and he eschewed a teaching position for field work. He made regular trips to the American West, prospecting in the 1870s and 1880s, often as a member of United States Geological Survey teams. A personal feud between Cope and paleontologist Othniel Charles Marsh led to a period of intense fossil-finding competition ...

Savannah River
The Savannah River is a major river in the southeastern United States, forming most of the border between the states of South Carolina and Georgia. Two tributaries of the Savannah, the Tugaloo River and the Chattooga River, form the northernmost part of the border. The Savannah River drainage basin extends into the southeastern side of the Appalachian Mountains just inside North Carolina, bounded by the Eastern Continental Divide. The river is around long.U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map, accessed April 26, 2011 The Savannah was formed by the confluence of the Tugaloo River and the Seneca River. Today this confluence is submerged beneath Lake Hartwell. The Tallulah Gorge is located on the Tallulah River, a tributary of the Tugaloo River that forms the northwest branch of the Savannah River. Two major cities are located along the Savannah River: Savannah and Augusta, Georgia. They were nuclei of early Eng ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Of The Eastern United States
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. Mos ...

Nocomis Micropogon
The river chub (''Nocomis micropogon'') is a minnow in the family Cyprinidae. It is one of the most common fishes in North American streams. Appearance and anatomy The river chub is a robust minnow, dark olivaceous above to dusky yellow below, with orange-red fins, large scales, a large slightly subterminal mouth, and a small barbel (whisker-like organ) at the corners of the jaw. During the breeding season, sexually mature males develop pinkish-purple coloration, and swollen heads with tubercles between the eyes and snout tip (they are sometimes called hornyheads).Etnier, David A and Wayne C Starnes. ''The Fishes of Tennessee'', (Knoxville: University of Tennessee Press, 1993), pp. 196-199. The river chub grows to a maximum of about , with males larger than females. Common length is about .

Spawn (biology)
Spawn is the Egg cell, eggs and Spermatozoa, sperm released or deposited into water by aquatic animals. As a verb, ''to spawn'' refers to the process of releasing the eggs and sperm, and the act of both sexes is called spawning. Most aquatic animals, except for aquatic mammals and marine reptile, reptiles, reproduce through the process of spawning. Spawn consists of the reproductive cells (gametes) of many aquatic animals, some of which will become fertilized and produce offspring. The process of spawning typically involves females releasing Ovum, ova (unfertilized eggs) into the water, often in large quantities, while males simultaneously or sequentially release spermatozoa (milt) to fertilize the eggs. Most fish reproduce by spawning, as do most other aquatic animals, including crustaceans such as crabs and shrimps, molluscs such as oysters and squid, echinoderms such as sea urchins and sea cucumbers, amphibians such as frogs and newts, aquatic insects such as mayflies and mos ...

Bigeye Shiner
The bigeye shiner (''Notropis boops'') is a species of ray-finned fish in the genus ''Notropis''. This fish is a slender, silvery minnow with a dusky lateral stripe and a maximum total length of about 80 mm. Its distinct characteristic is its large-diameter eyes. It is a common species in upland streams of the middle Mississippi River system. Bigeye shiners prefer warm, quiet pools with clear water and silt-free substrates. Siltation, channelization, and gravel dredging are all threats to bigeye shiner populations.Rice, Daniel, Mark Barnes, and George Phinney. 1998. A review and recent records of the bigeye shiner, ''Notropis boops'' (Cyprinidae), in Ohio. "Ohio Journal of Science" 98(3):42-51. During spawning season, typically late April to August, bigeye shiners have several clutches of eggs. State agencies and the EPA have both played a role in the surveying of bigeye shiner populations. Populations have decreased in Ohio due mostly to habitat destruction Habitat des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telescope Shiner
The telescope shiner (''Notropis telescopus'') is a species of ray-finned fish in the genus ''Notropis''. ''Notropis telescopus'' is primarily found in a small range of waters located in the Southeastern Region of the United States. There is very little published record of the research and management involving the telescope shiner. The following research will provide information on this species that can be helpful toward monitoring efforts of ''Notropis telescopus'' populations. The primary population of telescope shiners occurs throughout drainages of the Tennessee and Cumberland Rivers. This population is distributed throughout Virginia, Kentucky, Tennessee, and Alabama. A second known population occurs in Arkansas and Missouri and is found in the White and Black river systems. The telescope shiner gets its name due to the relatively large eye it possesses compared to other ''Notropis'' species. Adult telescopus usually have a length range from 50 to 105 mm.

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 ...

Fishing Bait
Fishing bait is any substance used to attract and catch fish, e.g. on a fishing hook. Bait items are both selected from and placed within the environment to achieve enhanced prey capture success. Traditionally, fishing baits are natural fish food such as night-crawlers, insects, worms, and smaller bait fish that have been used for catching fish. Fishermen have also begun using processed food, plastic baits and more recently, bionic lures to attract fish. Despite the importance of fish's attraction to bait, the way fish react to different baits is quite poorly understood. The various techniques and bait that a fisher may choose is dictated mainly by the target species and by its habitat. Bait can be separated into two main categories: artificial baits and natural baits. The alternative of artificial and live baits frequently demonstrate similar efficiency. The overall bait type and size will affect the efficiency and results of catches when fishing. With these two common w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Introduced Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and neophyt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
