Amistad Reservoir
Amistad Reservoir () is a Reservoir (water), reservoir on the Rio Grande at its confluence with the Devils River (Texas), Devils River northwest of Del Rio, Texas, Del Rio, Texas. The lake is bounded by Val Verde County, Texas, Val Verde County on the United States side of the international border and by the state of Coahuila on the Mexico, Mexican side of the border; the American shoreline forms the Amistad National Recreation Area. The reservoir was formed in 1969 by the construction of Amistad Dam. The dam and lake are managed jointly by the governments of the United States and Mexico through the International Boundary and Water Commission. The name of the dam and lake is the Spanish language, Spanish word for "friendship". The reservoir is also known as Lake Amistad. Hydrology Amistad Reservoir is part of the Rio Grande, which forms its principal inflow at its northwestern end. The other major inflow is the Devils River (Texas), Devils River, which enters from the north. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Val Verde County, Texas
Val Verde County is a county located on the southern Edwards Plateau in the U.S. state of Texas. The 2020 population is 47,586. Its county seat is Del Rio. The Del Rio micropolitan statistical area includes all of Val Verde County. Val Verde, which means "green valley", was named for a battle of the Civil War. In 1862, soldiers of Sibley's Brigade took part in the Texas invasion of New Mexico Territory, where they captured several artillery pieces at the Battle of Val Verde. The battle is memorialized both in the name of the county and a small settlement in Milam County. History Early history The first inhabitants of what is now known as Val Verde County lived there some 6,000–10,000 years ago. Their descendants include such Native American peoples as the Lipan Apache, Coahuiltecan, Jumano, Tamaulipan and Comanche. Colonial rule In 1590, Spanish explorer Gaspar Castaño de Sosa led a mining expedition of 170 who passed through Devils Draw. He referred to a st ...

Endemism
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Amistad Gambusia
The Amistad gambusia (''Gambusia amistadensis'') is an extinct species of small fish known only from a single locality, the large vegetated Goodenough Spring in Val Verde County, Texas. It apparently was driven to extinction in the wild when its habitat was submerged to a depth of about 70 feet by the construction of the Amistad Reservoir in 1968. The two captive populations, at the University of Texas System and the Dexter National Fish Hatchery in New Mexico, later failed through hybridization with the related mosquitofish and predation. The species has been classified as extinct by the United States Fish and Wildlife Service since 1987, and by the IUCN The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status ... since 2013. References Further reading * Gambusia Fish described i ...

Texas Parks And Wildlife Department
The Texas Parks & Wildlife Department (TPWD) is a Texas state agency that oversees and protects wildlife and their habitat (ecology), habitats. In addition, the agency is responsible for managing the state park, state's parks and historical areas. Its mission is to manage and conserve the natural and cultural resources of Texas and to provide hunting, fishing, and outdoor recreation opportunities for the use and enjoyment of present and future generations. The agency maintains its headquarters at 4200 Smith School Road in Austin, Texas. History In 1895, the Texas Legislature created the Fish and Oyster Commission to regulate fishing. The legislature added the Game Department to the commission in 1907. The Legislature created the State Parks Board as a separate entity in 1923. In 1963, the Texas Parks and Wildlife Department was formed through merger of the State Parks Board and the Game and Fish Commission. In 1983, the Texas legislature passed the Wildlife Conservation Act ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrilla
''Hydrilla'' (waterthyme) is a genus of aquatic plant, usually treated as containing just one species, ''Hydrilla verticillata'', though some botanists divide it into several species. It is native to the cool and warm waters of the Old World in Asia, Africa and Australia, with a sparse, scattered distribution; in Australia from Northern Territory, Queensland, and New South Wales.Flora Europaea''Hydrilla''/ref>Flora of Taiwan''Hydrilla'' The stems grow up to 1–2 m long. The leaves are arranged in whorls of two to eight around the stem, each leaf 5–20 mm long and 0.7–2 mm broad, with serrations or small spines along the leaf margins; the leaf midrib is often reddish when fresh. It is monoecious (sometimes dioecious), with male and female flowers produced separately on a single plant; the flowers are small, with three sepals and three petals, the petals 3–5 mm long, transparent with red streaks. It reproduces primarily vegetatively by fragmentation and by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catfish
Catfish (or catfishes; order (biology), order Siluriformes or Nematognathi) are a diverse group of ray-finned fish. Catfish are common name, named for their prominent barbel (anatomy), barbels, which resemble a cat's whiskers, though not all catfish have prominent barbels or "whiskers", with some seemingly not having them. Siluriformes as a whole are Fish scale, scale-less, with neither the Armoured catfish, armour-plated nor the naked species having scales. This order of fish are Autapomorphy, defined by features of the skull and swimbladder. Catfish range in size and behavior from the three List of largest fish, largest species alive, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia, and the piraÃba of South America, to detritivorous and scavenging bottom feeders, down to tiny ectoparasitic species known as the Candiru (fish), candirus.

Guadalupe Bass
The Guadalupe bass (''Micropterus treculii'') is a rare species of fish endemic to the U.S. state of Texas, where it also is the official state fish. It is restricted to creeks and rivers (including the Guadalupe River, hence the name Guadalupe bass), and is listed as near threatened. Today, most fly fishermen and anglers practice catch-and-release techniques to improve fish populations. The Guadalupe bass is often difficult to distinguish from the smallmouth bass or spotted bass, and the fish is known to hybridize. Description and range Guadalupe bass, like most black bass, are lime to olive green in color, this particular species being lighter in shade usually in river specimens. They have a lateral line covered in mostly separate diamond-shaped or circular spots, which with age fade from black to olive. Also, many smaller diamond marks are scattered on the back, which are less distinguished than the ones on the lateral line. They have a rectangular tooth patch on the tongu ...
