Pomacea Ocanensis
''Pomacea ocanensis'' is a species of freshwater snail in the Ampullariidae family. Wilhelm Kobelt originally described the species as a subspecies of '' Ampullaria auriformis'' in 1914. It is native to Colombia and resides in the shallow margins of the Magdalena River near Ocaña, Norte de Santander. A critically endangered species, ''P. ocanensis'' faces threats of declining habitat quality due to urbanization, local water management, and pollution. It is the only member of ''Pomacea'' considered Endangered or Critically Endangered by the IUCN and one of only two Ampullariids to be Critically Endangered.

Wilhelm Kobelt
Wilhelm Kobelt (20 February 1840 – 26 March 1916) was a German zoologist born in Alsfeld, Grand Duchy of Hesse. He specialized in the field of malacology. Kobelt is remembered for his work as curator of the Senckenberg Museum in Frankfurt am Main. Several species of mollusk contain his name, including '' Fusinus kobelti'' (Kobelt's spindle), '' Cymatium kobelti'' and '' Hyalinia kobelti''. '' Kobeltia'', a subgenus of '' Arion'' slugs, is named in honor of him.

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freshwater Snail
Freshwater snails are gastropod mollusks which live in fresh water. There are many different families. They are found throughout the world in various habitats, ranging from ephemeral pools to the largest lakes, and from small seeps and springs to major rivers. The great majority of freshwater gastropods have a shell, with very few exceptions. Some groups of snails that live in freshwater respire using gills, whereas other groups need to reach the surface to breathe air. In addition, some are amphibious and have both gills and a lung (e.g. ''Ampullariidae''). Most feed on algae, but many are detritivores and some are filter feeders. According to a 2008 review of the taxonomy, there are about 4,000 species of freshwater gastropods (3,795–3,972). At least 33–38 independent lineages of gastropods have successfully colonized freshwater environments. It is not possible to quantify the exact number of these lineages yet, because they have yet to be clarified within the Cerit ...

Ampullariidae
Ampullariidae, commonly known as the apple snails, is a family of large freshwater snails, aquatic gastropod mollusks with a gill and an operculum. These snails simultaneously have a gill and a lung as functional respiratory structures, which are separated by a division of the mantle cavity. This adaptation allows these animals to be amphibious. Species in this family are considered gonochoristic, meaning that each individual organism is either male or female. Systematics and taxonomy Ampullariidae belongs to the superfamily Ampullarioidea, and is also its type family. It comprised two subfamilies according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005, which followed the classification proposed by Berthold (1991), including Ampullariinae Gray, 1824, and Afropominae Berthold, 1991. The current classification accepted by WoRMS includes Ampullariinae and Pomaceinae Starobogatov, 1983. Genera Ampullariidae are probably of Gondwanan origin, and the divers ...

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ampullaria Auriformis
''Pomacea auriformis'' is a species of freshwater snail in the family Ampullariidae, described by Lovell Augustus Reeve in 1856 as ''Ampullaria auriformis''. Its distribution is along the Caribbean coast of Central America.

Colombia
Colombia (, ; ), officially the Republic of Colombia, is a country in South America with insular regions in North America—near Nicaragua's Caribbean coast—as well as in the Pacific Ocean. The Colombian mainland is bordered by the Caribbean Sea to the north, Venezuela to the east and northeast, Brazil to the southeast, Ecuador and Peru to the south and southwest, the Pacific Ocean to the west, and Panama to the northwest. Colombia is divided into 32 departments and the Capital District of Bogotá, the country's largest city. It covers an area of 1,141,748 square kilometers (440,831 sq mi), and has a population of 52 million. Colombia's cultural heritage—including language, religion, cuisine, and art—reflects its history as a Spanish colony, fusing cultural elements brought by immigration from Europe and the Middle East, with those brought by enslaved Africans, as well as with those of the various Amerindian civilizations that predate colonization.

Magdalena River
The Magdalena River ( es, Río Magdalena, ; less commonly ) is the main river of Colombia, flowing northward about through the western half of the country. It takes its name from the biblical figure Mary Magdalene. It is navigable through much of its lower reaches, in spite of the shifting sand bars at the mouth of its delta, as far as Honda, at the downstream base of its rapids. It flows through the Magdalena River Valley. Its drainage basin covers a surface of , which is 24% of the country's area and where 66% of its population lives. Course The Magdalena River is the largest river system of the northern Andes, with a length of 1,612 km. Its headwaters are in the south of Colombia, where the Andean subranges Cordillera Central and Cordillera Oriental separate, in Huila Department. The river runs east then north in a great valley between the two cordilleras. It reaches the coastal plain at about nine degrees north, then runs west for about , then north again, reaching th ...

Ocaña, Norte De Santander
Ocaña is a town and municipality in the Colombian Departments of Colombia, Department of Norte de Santander. Ocaña is the second largest populated center of this department. It played an important role during the Military career of Simón Bolívar, Independence of Colombia from the Spanish monarchy. History The city was founded on 14 December of 1570 by Captain Francisco Fernández de Contreras, as part of the third populating project of the east, patronised by the Audiencia y Cabildo de Pamplona. Contreras chose the Hacaritama Indigenous Society in order to have more control over the indigenous population of the area and thus be able to found the city. The first name the city received was Santa Ana de Hacarí when it was founded in 1570. During 1575, it was assigned the status of city with its current name, Ocaña. During the time of colonization, Fernandez de Contreras stated that all merchandise coming from Spain and destined for the Magdalena River, Madgalena River should p ...

Pomacea
''Pomacea'' is a genus of freshwater snails with gills and an operculum, aquatic gastropod mollusks in the family Ampullariidae, the apple snails. The genus is native to the Americas; most species in this genus are restricted to South America. in the aquarium trade these snails are sometimes called ''Pomacea'' or incorrectly ''Ampullarius'', and in English as "olormystery snail" or "apple snail". Some species have been introduced outside their native range and are considered invasive because of their voracious appetite for plants. Because of this, imports involving this genus are restricted in some regions (including the United States) and are entirely banned in others (including the EU).Dawes, J. (14 January 2013).

Endangered
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
