Moxostoma Ugidatli
The sicklefin redhorse (''Moxostoma ugidatli''), is a species of freshwater Actinopterygii, ray-finned fish in the genus ''Moxostoma''. It is Endemism, endemic to the southeastern United States, where it is known from a small section of the Appalachian Mountains in southwestern North Carolina and northern Georgia (U.S. state), Georgia. Long known to the Cherokee people, it was only scientifically recognized as a distinct species in 1992, and only officially given a scientific name in 2025. The fish was once an important food source to the Eastern Band of Cherokee Indians before it nearly disappeared in the 1970s and 1980s. A number of groups and agencies are attempting to preserve the fish, including the N.C. Wildlife Resources Commission, Duke Energy, the Tennessee Valley Authority, the Eastern Band of Cherokee Indians, the Georgia Department of Natural Resources, and the U.S. Fish and Wildlife Service. Taxonomy Etymology According to various sources it is called ugidatli ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Actinopterygii
Actinopterygii (; ), members of which are known as ray-finned fish or actinopterygians, is a class (biology), class of Osteichthyes, bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fish fin, fins made of webbings of skin supported by radially extended thin bony spine (zoology), spines called ''lepidotrichia'', as opposed to the bulkier, fleshy lobed fins of the sister taxon, sister clade Sarcopterygii (lobe-finned fish). Resembling folding fans, the actinopterygian fins can easily change shape and wetted area, providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins. The fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the articulation (anatomy), articulation between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). The vast majority of actinopterygians are teleosts. By species count, they domi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salmon
Salmon (; : salmon) are any of several list of commercially important fish species, commercially important species of euryhaline ray-finned fish from the genera ''Salmo'' and ''Oncorhynchus'' of the family (biology), family Salmonidae, native to tributary, tributaries of the North Atlantic (''Salmo'') and North Pacific (''Oncorhynchus'') basins. ''Salmon'' is a colloquial or common name used for fish in this group, but is not a scientific name. Other closely related fish in the same family include trout, Salvelinus, char, Thymallus, grayling, Freshwater whitefish, whitefish, lenok and Hucho, taimen, all coldwater fish of the subarctic and cooler temperate regions with some sporadic endorheic populations in Central Asia. Salmon are typically fish migration, anadromous: they hatch in the shallow gravel stream bed, beds of freshwater headstreams and spend their juvenile fish, juvenile years in rivers, lakes and freshwater wetlands, migrate to the ocean as adults and live like sea ...

Greenfin Darter
The greenfin darter (''Etheostoma chlorobranchium'') 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 is endemic to the eastern United States. Geographic distribution The greenfin darter is primarily restricted to the fast-flowing, mountainous streams and rivers of the upper Tennessee River drainage area, in North Carolina, Georgia, and Tennessee. The species' range stretches from the upper Holston and Watauga Rivers, south through the French Broad and Little Tennessee Rivers, and ultimately ends at the Hiwassee River.Etnier, D. A., & Starnes, W. C. (1993). Fishes of Tennessee (pp. 478–479). University of Tennessee press. Ecology The greenfin darter is a benthic insectivore, feeding mainly on insect larvae in cold, high-elevation creeks and rivers.

Ridge-and-Valley Appalachians
The Ridge-and-Valley Appalachians, also called the Ridge and Valley Province or the Valley and Ridge Appalachians, are a physiographic province of the larger Appalachian Highlands division. The physiographic province is divided into three sections: the Hudson Valley, the Central, and the Tennessee. The river valleys were areas of indigenous settlements for thousands of years. In the historic period, the Cherokee people had towns along many of the rivers in western South Carolina and North Carolina, as well as on the western side of the Appalachian Mountains in present-day Tennessee. Similarly, the Catawba people occupied areas along the upper Catawba River in Western North Carolina, to the east of Cherokee County. The ridge and valley system presents an important obstacle to east–west land travel even with today's technology. It was a nearly insurmountable barrier to European-American migrants who walked or rode horses traveling west to settle the Ohio Country, and ...

Sedimentary Rock
Sedimentary rocks are types of rock (geology), rock formed by the cementation (geology), cementation of sediments—i.e. particles made of minerals (geological detritus) or organic matter (biological detritus)—that have been accumulated or deposited at Earth's surface. Sedimentation is any process that causes these particles to settle in place. Geological detritus originates from weathering and erosion of existing rocks, or from the solidification of molten lava blobs erupted by volcanoes. The geological detritus is transported to the place of deposition by water, wind, ice or Mass wasting, mass movement, which are called agents of denudation. Biological detritus is formed by bodies and parts (mainly shells) of dead aquatic organisms, as well as their fecal mass, suspended in water and slowly piling up on the floor of water bodies (marine snow). Sedimentation may also occur when dissolved minerals precipitate from aqueous solution, water solution. The sedimentary rock cover of ...

Metamorphic Rock
Metamorphic rocks arise from the transformation of existing rock to new types of rock in a process called metamorphism. The original rock ( protolith) is subjected to temperatures greater than and, often, elevated pressure of or more, causing profound physical or chemical changes. During this process, the rock remains mostly in the solid state, but gradually recrystallizes to a new texture or mineral composition. The protolith may be an igneous, sedimentary, or existing metamorphic rock. Metamorphic rocks make up a large part of the Earth's crust and form 12% of the Earth's land surface. They are classified by their protolith, their chemical and mineral makeup, and their texture. They may be formed simply by being deeply buried beneath the Earth's surface, where they are subject to high temperatures and the great pressure of the rock layers above. They can also form from tectonic processes such as continental collisions, which cause horizontal pressure, friction, and dist ...

Late Miocene
The Late Miocene (also known as Upper Miocene) is a sub-epoch of the Miocene epoch (geology), Epoch made up of two faunal stage, stages. The Tortonian and Messinian stages comprise the Late Miocene sub-epoch, which lasted from 11.63 Ma (million years ago) to 5.333 Ma. The evolution of ''Homo'' The gibbons (family Hylobatidae) and orangutans (genus ''Pongo'') were the first groups to split from the line leading to the hominins, including humans, then gorillas (genus ''Gorilla''), and finally chimpanzees and bonobos (genus ''Pan (genus), Pan''). The splitting date between hominin and chimpanzee lineages is placed by some between 4 and 8 million years ago, that is, during the Late Miocene.

Shorthead Redhorse
The shorthead redhorse (''Moxostoma macrolepidotum'') is a wide-ranging species in North America. The shorthead redhorse is native to central and eastern North America. However, its range has expanded to include areas like the Hudson estuary and Grayson County, Texas. It inhabits small to large rivers and lakes, and lives in the benthic zone. Shorthead redhorse feed on benthic invertebrates and can consume plant material from the benthic environment that it inhabits. When it spawns, shorthead redhorse move into more shallow streams and spawn over gravel or rocky shoals. They will also spawn in springs with swift moving water. The shorthead redhorse is important to humans because it is a game fish. It is also important to anglers because of its role in the ecosystem; it is prey for larger game fish such as northern pike and muskellunge. One source gives one of its English names as "common mullet". Others are redfin, redfin sucker, red sucker, redhorse mullet, shorthead mullet, mu ...

River Redhorse
The river redhorse (''Moxostoma carinatum'') is a species of freshwater fish endemic to the eastern half of the United States and southeastern Canada. They can range from 10 to 30 inches in length and can potentially reach a weight of more than 10 pounds after maturity. It is typically found in clear, large creeks and rivers, though it is sometimes also found in lakes. They are sometimes speared or caught with hook and line using crayfish or worms as bait. A bottom-feeder, it feeds on mussels, snails, crustaceans and immature aquatic insects. Its common names include big-sawed sucker, river mullet, greater redhorse, redfin redhorse and redhorse sucker. It has the following characteristics: Distribution The river redhorse occurs throughout the central and eastern Mississippi River System and the Gulf Slope from Florida to Louisiana. In Canada, its distribution is characterized by disjunct populations in southern Ontario and Quebec as well as Alberta. This species has declined cons ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera. Hybrids are not always intermediates between their parents such as in blending inheritance (a now discredited theory in modern genetics by particulate inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridization, which include genetic and morph ...
