Andinoacara Latifrons
''Andinoacara latifrons'', the platinum acara, is a species of fish in the family Cichlidae in the order Perciformes, native to the Magdalena, Atrato, Sinú, and San Juan River basins in Colombia. Description Males can reach a length of total in length. It has a stocky body with a bluish-grey colouration. It has lighter speckles across the scales, with relatively long fins. It is similar in appearance to the blue acara. Spawning The platinum acara spawns several times each year. As with most cichlids there are frequent quarrels between partners. The female cleans a stone carefully and lays eggs on it afterward. They are attached to one another, resembling a pearl necklace. As they begin to increase in size the stone is completely covered by them. The female fans them with her body and pectoral fins. Once the fry have emerged and can swim independently they surround their parents in a great shoal. References Bibliography * Arai, R. y H. Kobayasi, 1973. A chromosome s ...

The IUCN Red List Of Threatened Species
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 provide sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sinú River
Sinú River (), is a river in northwestern Colombia that flows mostly through the Córdoba Department and into the Caribbean. The river is the third most important river after the Magdalena River and the Cauca River in the Caribbean Region. It is born in the Antioquia Department, flowing south to north for until flowing into the Caribbean Sea. The river is navigable for only half of its length, starting in Montería, the largest city in its basin. Also, this river is the main tourist attraction of Montería decorated with the first avenue when it passes by Montería. Ecology The river flows through the Sinú Valley dry forests ecoregion. In general, the aquatic fauna shows connections with the Magdalena–Cauca River basin, but also the Atrato River basin. There has been extensive habitat destruction in the region, causing problems to many species in the area. Two parrots that are endemic to the river valley, the Sinú brown-throated parakeet (''Aratinga pertinax griseipect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Andinoacara
''Andinoacara'' is a genus of fish in the family Cichlidae. The genus was described in 2009.Musilova, Rican and Novak, 2009''Phylogeny of the Neotropical cichlid fish tribe Cichlasomatini (Teleostei: Cichlidae) based on morphological and molecular data, with the description of a new genus''.Journal of Zoological Systematics and Evolutionary Research, Volume 47 Issue 3, Pages 209 - 304 (August 2009) Before this the members of ''Andinoacara'' were placed in the "catch-all" genus ''Aequidens'' although they are not closely related to the other members of this genus. The genus ''Andinoacara'' is restricted to freshwater habitats in northwestern South America (Trinidad and the Orinoco Basin west to the Pacific coast of South America as far south as Peru) and southern Central America (Costa Rica and Panama). There are no members of the genus in the Amazon Basin. Species There are currently eight recognized species in this genus:Eschmeyer, W.N., & R. Fricke, eds. (2013). Catalog of Fishe ...

Alemania
Alamannia, or Alemannia, was the kingdom established and inhabited by the Alemanni, a Germanic tribal confederation that had broken through the Roman ''limes'' in 213. The Alemanni expanded from the Main River basin during the 3rd century and raided Roman provinces and settled on the left bank of the Rhine River from the 4th century. Ruled by independent tribal kings during the 4th and the 5th centuries, Alamannia lost its independence and became a duchy of the Frankish Empire in the 6th century. As the Holy Roman Empire started to form under King Conrad I of East Francia (reigning 911 to 918), the territory of Alamannia became the Duchy of Swabia in 915. Scribes often used the term '' Suebia'' interchangeably with ''Alamannia'' in the 10th to the 12th centuries. The territory of Alamannia as it existed from the 7th to 9th centuries centred on Lake Constance and included the High Rhine, the Black Forest and the Alsace on either side of the Upper Rhine, the upper Danube River ...

Cichlids
Cichlids are fish from the family (biology), family Cichlidae in the order Cichliformes. Cichlids were traditionally classed in a suborder, the Labroidei, along with the wrasses (Labridae), in the order Perciformes, but molecular studies have contradicted this grouping. The closest living relative of cichlids is probably the Pholidichthys leucotaenia, convict blenny, and both families are classified in the 5th edition of ''Fishes of the World'' as the two families in the Cichliformes, part of the subseries Ovalentaria. This family is both large and diverse. At least 1,650 species have been Binomial nomenclature, scientifically described, making it one of the largest vertebrate families. New species are discovered annually, and many species remain Undescribed taxon, undescribed. The actual number of species is therefore unknown, with estimates varying between 2,000 and 3,000. Many cichlids, particularly tilapia, are important food fishes, while others, such as the ''Cichla'' spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
