Elassoma Alabamae
The spring pygmy sunfish, ''Elassoma alabamae'', is a species of pygmy sunfish Endemism, endemic to spring (hydrology), springs in northern Alabama. It was historically known to occur in springs in North Alabama along the Tennessee River in Limestone and Lauderdale counties. The spring pygmy sunfish was first discovered in Cave Spring in Lauderdale County, Alabama in 1937 but in 1938, this site was flooded by the creation of the Pickwick Reservoir. The spring pygmy sunfish was considered extinct until its rediscovery in the Beaverdam Spring complex in 1973 by researchers from the University of Tennessee. Appearance The spring pygmy sunfish is a small fish that rarely exceeds an inch long. Males and females exhibit different coloration. Breeding males are vividly colored. Overall the breeding male is very dark except for vertical, iridescent blue-green bars along the body and iridescent mottling on the cheek. Females are more muted in coloration when compared to the males. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Richard L
Richard is a male given name. It originates, via Old French, from Old Frankish and is a compound of the words descending from Proto-Germanic ''*rīk-'' 'ruler, leader, king' and ''*hardu-'' 'strong, brave, hardy', and it therefore means 'strong in rule'. Nicknames include "Richie", "Dick", "Dickon", " Dickie", "Rich", "Rick", "Rico", "Ricky", and more. Richard is a common English, German and French male name. It's also used in many more languages, particularly Germanic, such as Norwegian, Danish, Swedish, Icelandic, and Dutch, as well as other languages including Irish, Scottish, Welsh and Finnish. Richard is cognate with variants of the name in other European languages, such as the Swedish "Rickard", the Catalan "Ricard" and the Italian "Riccardo", among others (see comprehensive variant list below). People named Richard Multiple people with the same name * Richard Andersen (other) * Richard Anderson (other) * Richard Cartwright (other) * Ri ...

Center For Biological Diversity
The Center for Biological Diversity is a nonprofit membership organization known for its work protecting endangered species through legal action, scientific petitions, creative media and grassroots activism. It was founded in 1989 by Kieran Suckling, Peter Galvin, Todd Schulke and Robin Silver. The Center is based in Tucson, Arizona, with its headquarters in the historic Owls club building, and has offices and staff in New Mexico, Nevada, California, Oregon, Illinois, Minnesota, Alaska, Vermont, Florida and Washington, D.C. Background Given a small grant by the Fund For Wild Nature, the organization started in 1989 as a small group by the name of ''Greater Gila Biodiversity Project'', with the objective to protect endangered species and critical habitat in the Southwestern United States. The organization grew and became the Center for Biological Diversity. Kieran Suckling, Peter Galvin, and Todd Schulke founded the organization in response to what they perceived as a failure on ...

Freshwater Fish Of The United States
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh wa ...

Endemic Fish Of The United States
Endemism is the state of a species being found 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 be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elassoma
''Elassoma'' is a genus of freshwater fish, the only member of subfamily Elassomatinae of the sunfish family Centrarchidae in the order Perciformes. It is sometimes classified as a separate family, the Elassomatidae, in a monotypic suborder, Elassomatoidei, in Perciformes. The type species is ''E. zonatum,'' the banded pygmy sunfish. The Elassomatinae are known collectively as pygmy sunfishes, but are considered by some authorities not to be true sunfishes, which are members of family Centrarchidae. Some researchers believe they are related to sticklebacks and pipefishes (order Syngnathiformes) rather than Perciformes, though genetic research strongly implies a close relationship with the centrarchids. Currently the Integrated Taxonomic Information System classifies them in the family Elassomatidae rather than Centrarchidae. The pygmy sunfishes grow to a maximum overall length of . They occur mostly in temperate and subtropical swamps, marshes, and other shallow, slow-moving ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overgrazing
Overgrazing occurs when plants are exposed to intensive grazing for extended periods of time, or without sufficient recovery periods. It can be caused by either livestock in poorly managed agricultural applications, game reserves, or nature reserves. It can also be caused by immobile, travel restricted populations of native or non-native wild animals. Overgrazing reduces the usefulness, productivity, and biodiversity of the land and is one cause of desertification and erosion. Overgrazing is also seen as a cause of the spread of invasive species of non-native plants and of weeds. Degrading land, emissions from animal agriculture and reducing the biomass in a ecosystem contribute directly to climate change. Overgrazing can be reversed or prevented by removing grazers in order to give plants time to recover between grazing events. Successful planned grazing strategies have been support in the American bison of the Great Plains, or migratory Wildebeests of the African savann ...

Wheeler National Wildlife Refuge
The Wheeler National Wildlife Refuge is a 35,000 acre (142 km2) National Wildlife Refuge located along the Tennessee River near Decatur, Alabama. Named after Major General Joseph Wheeler, it was established to provide a habitat for wintering and migrating birds in the eastern United States.

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
