Geophagus Surinamensis
''Geophagus'' is a genus of cichlids that mainly live in South America as far south as Argentina and Uruguay, but a single species, ''G. crassilabris'' is from Panama.Mattos, J.L.O., Costa, W.J.E.M. & Santos, A.C.A. (2015): ''Geophagus diamantinensis'', a new species of the ''G. brasiliensis'' species group from Chapada Diamantina, north-eastern Brazil (Cichlidae: Geophagini). ''Ichthyological Explorations of Freshwaters, 26 (3): 209-220.'' They are found in a wide range of freshwater habitats. They are part of a group popularly known as eartheaters and mostly feed by picking up mouthfuls of sediment to sift out food items such as invertebrates, plant material and detritus. The largest species reach up to in standard length. They are often kept in aquariums. As an invasive species Geophagus Surinamensis was an invasive species in Malaysia, recently found in Putrajaya, the populations are now controlled by giant snakeheads.

Geophagus Altifrons
''Geophagus altifrons'' is a freshwater eartheater cichlid fish native to the Amazon River Basin, Brazil. Introduced to Singapore, it thrives in slow-moving streams and reservoirs. Its ecological impact on its adopted habitat In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical ... is still unknown. A member of the family Cichlidae, it can grow up to in standard length. It is benthophagous by nature, taking mouthfuls of substrate (hence its common name) and sifting for edible items, with the remaining materials being expelled via the mouth and gill openings. It prefers clear and blackwater environments as opposed to turbid white waters.

Hernán López-Fernández
Hernán is a Spanish masculine given name, originating from Germanic Hernan in the Visigoth culture in Spain. It is the Latinized version of the compound name ''Fard-nanth'', which seems to mean "gentle traveler" or "spiritual traveler". The House of Hernán gave its name to those with the surname Hernández, the -ez at the end denoting membership of that House. The surname, like many Spanish surnames, is of Teutonic-Gothic origin. It is not connected with "Herman" - also of Germanic origin, but a different one. Persons with the given name include: * Hernán Alvarado Solano (1946–2011), Colombian Roman Catholic bishop * Hernán Andrade (born 1960), Mexican racewalker * Hernán Barcos (born 1984), Argentinian football player * Hernán Barreneche (born 1939), retired long-distance runner * Hernán Behn (19th century), Puerto Rican businessperson * Hernán Bernardello (born 1986), Argentine football midfielder * Hernán Boyero (born 1979), Argentine football striker * Hernán B ...

Andes
The Andes, Andes Mountains or Andean Mountains (; ) are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is long, wide (widest between 18°S – 20°S latitude), and has an average height of about . The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina. Along their length, the Andes are split into several ranges, separated by intermediate depressions. The Andes are the location of several high plateaus—some of which host major cities such as Quito, Bogotá, Cali, Arequipa, Medellín, Bucaramanga, Sucre, Mérida, El Alto and La Paz. The Altiplano plateau is the world's second-highest after the Tibetan plateau. These ranges are in turn grouped into three major divisions based on climate: the Tropical Andes, the Dry Andes, and the Wet Andes. The Andes Mountains are the highest m ...

Species Complex
In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each other, further blurring any distinctions. Terms that are sometimes used synonymously but have more precise meanings are cryptic species for two or more species hidden under one species name, sibling species for two (or more) species that are each other's closest relative, and species flock for a group of closely related species that live in the same habitat. As informal taxonomic ranks, species group, species aggregate, macrospecies, and superspecies are also in use. Two or more taxa that were once considered conspecific (of the same species) may later be subdivided into infraspecific taxa (taxa within a species, such as bacterial strains or plant varieties), that is complex but it is not a species complex. A species complex is in most ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Parnaíba River
The Parnaíba River ( pt, Rio Parnaíba) is a river in Brazil, which forms the border between the states of Maranhão and Piauí. Its main course is long and the Parnaíba River Basin covers .Ramos, T.P.A.; Ramos, R.T.C.; and Ramos, S.A.Q.A. (2014). Ichthyofauna of the Parnaíba river Basin, Northeastern Brazil.' Biota Neotrop. 14(1). The Parnaíba River rises in the Chapada das Mangabeiras range, and flows northeastward to empty into the Atlantic Ocean, being the longest river entirely located within Brazil's Northeast Region. The middle and upper regions of this river are separated by the pt, Boa Esperança Hydroelectric Power Plant dam, but is otherwise navigable. Ecology The fish species richness in the Parnaíba River Basin has traditionally been considered impoverished, but this has been disproven by recent surveys, which have recorded about 140 native species (including several that remain undescribed) and about 40% of these are endemic. One of the basin endemics is th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orinoco
The Orinoco () is one of the longest rivers in South America at . Its drainage basin, sometimes known as the Orinoquia, covers , with 76.3 percent of it in Venezuela and the remainder in Colombia. It is the fourth largest river in the world by discharge volume of water. The Orinoco River and its tributaries are the major transportation system for eastern and interior Venezuela and the Llanos of Colombia. The environment and wildlife in the Orinoco's basin are extremely diverse. Etymology The river's name is derived from the Warao term for "a place to paddle", itself derived from the terms ''güiri'' (paddle) and ''noko'' (place) i.e. a navigable place. History The mouth of the Orinoco River at the Atlantic Ocean was documented by Christopher Columbus on 1 August 1498, during his third voyage. Its source at the Cerro Delgado–Chalbaud, in the Parima range, was not explored until 453 years later, in 1951. The source, near the Venezuelan–Brazilian border, at ab ...

Amazon Basin
The Amazon basin is the part of South America drained by the Amazon River and its tributaries. The Amazon drainage basin covers an area of about , or about 35.5 percent of the South American continent. It is located in the countries of Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Suriname, and Venezuela. Most of the basin is covered by the Amazon rainforest, also known as Amazonia. With a area of dense tropical forest, this is the largest rainforest in the world. Geography The Amazon River begins in the Andes Mountains at the west of the basin with its main tributary the Marañón River and Apurimac River in Peru. The highest point in the watershed of the Amazon is the second biggest peak of Yerupajá at . With a length of about before it drains into the Atlantic Ocean, it is one of the two longest rivers in the world. A team of scientists has claimed that the Amazon is longer than the Nile, but debate about its exact length continues. The Amazon s ...

Sensu Stricto
''Sensu'' is a Latin word meaning "in the sense of". It is used in a number of fields including biology, geology, linguistics, semiotics, and law. Commonly it refers to how strictly or loosely an expression is used in describing any particular concept, but it also appears in expressions that indicate the convention or context of the usage. Common qualifiers ''Sensu'' is the ablative case of the noun ''sensus'', here meaning "sense". It is often accompanied by an adjective (in the same case). Three such phrases are: *''sensu stricto'' – "in the strict sense", abbreviation ''s.s.'' or ''s.str.''; *''sensu lato'' – "in the broad sense", abbreviation ''s.l.''; *''sensu amplo'' – "in a relaxed, generous (or 'ample') sense", a similar meaning to ''sensu lato''. Søren Kierkegaard uses the phrase ''sensu eminenti'' to mean "in the pre-eminent r most important or significantsense".
