Aylacostoma Chloroticum
''Aylacostoma chloroticum'' is a species of freshwater snail, aquatic gastropod mollusc in the family Thiaridae. This species is found in Argentina and Paraguay. It was feared that the species had become extinct in the wild as a consequence of the building of the Yacyretá Dam on the Paraná River, but a single small wild population remains.Vogler, Beltramino, Strong & Rumi (2015).

Animalia
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinode ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Aylacostoma Stigmaticum
''Aylacostoma stigmaticum'' is a species of freshwater snail, aquatic gastropod mollusc in the family Thiaridae. This species disappeared after the building of the Yacyretá Dam on the Paraná River, in between Argentina and Paraguay. Although listed as extinct in the wild by the IUCN, no captive population survives meaning that it now is entirely extinct.Vogler (2013).

Aylacostoma Brunneum
''Aylacostoma'' is a genus of tropical freshwater snails with an operculum, aquatic gastropod molluscs in the family Hemisinidae. They are found in South and Central America. As a consequence of the Yacyretá Dam, two species are entirely extinct and another is extinct in the wild.Vogler (2013).

Bernardino Rivadavia Natural Sciences Museum
The Bernardino Rivadavia Natural Sciences Argentine Museum ( es, Museo Argentino de Ciencias Naturales Bernardino Rivadavia) is a public museum located in the Caballito section of Buenos Aires, Argentina. History and overview The museum owes its existence to a proposal made by Bernardino Rivadavia before the First Triumvirate of the United Provinces of the Río de la Plata in 1812. The ongoing struggle for Independence from the Spanish colonial period stalled Rivadavia's project, however, until 1823, when he promoted construction of a building for the museum as a member of Governor Martín Rodríguez's cabinet. The original museum opened in 1826 and was housed downtown in a loft inside the Santo Domingo Convent, which had been made available to host Rivadavia after his expulsion of the Dominican order from Buenos Aires. Rivadavia closely oversaw the construction of the institution, the first of its kind in South America, and appointed Italian Argentine botanist Carlos Ferraris ...

National University Of Misiones
The National University of Misiones (in Spanish: ''Universidad Nacional de Misiones'', ''UNaM'') is a public university in Argentina. It has a publishing house and a radio station, ''LRH301 FM Universidad Nacional de Misiones'', that streams in Ogg Vorbis format. History The university founded by the Argentine law 20.286 on April 16, 1973, as part of the Taquini plan, a program of reorganization of higher education in Argentina. This would involve the foundation of the universities of Jujuy, La Pampa, Lomas de Zamora, Entre Ríos, Luján, Catamarca, Salta, San Juan, San Luis and Santiago del Estero, to form more than 11.000 pupils, on border locations with Paraguay and Brazil. In 2021, the University awarded a posthumous "honoris causa" prize to the writer Eduardo Galeano.

Paraná River
The Paraná River ( es, Río Paraná, links=no , pt, Rio Paraná, gn, Ysyry Parana) is a river in south-central South America, running through Brazil, Paraguay, and Argentina for some ."Parana River".

Encyclopædia Britannica Inc., 2012. Web. 26 May. 2012 Among South American rivers, it is second in length only to the Amazon River. It merges with the Paraguay River and then farther downstream with the Uruguay River to form the Río de la Plata and empties into the Atlantic Ocean. The first European to go up the Paraná River was the Venetian explorer Sebastian Cabot, in 1526, while working for Spain. A drought hit the river in 2021, causing a 77-year low.

Yacyretá Dam
The Yacyretá Dam or Jasyretâ-Apipé Hydroelectric Power Station (from Guaraní ''jasy retã'', "land of the moon") is a dam and hydroelectric power plant built over the waterfalls of Jasyretâ-Apipé in the Paraná River, between the Paraguayan City of Ayolas and the Argentine Province of Corrientes. The dam is named for Yacyretá Island just upstream, much of which the dam submerged. The word "Yacyreta" is the Hispanicized spelling of the original Guaraní term Jasyretâ. The dam is long, and its installed equipment has a maximum power output of , with a record maximum annual power output of achieved in year 2012, and a maximum water flow rate of 55,000 cubic meters per second. Until February 2011, its reservoir was seven meters below its planned water level, only allowing it to operate at 60% capacity. The project generated controversy and criticism during its planning and construction because of the effects it had on local ecology, particularly the flooding of a uniqu ...

Extinct In The Wild
A species that is extinct in the wild (EW) is one that has been categorized by the International Union for Conservation of Nature as known only by living members kept in captivity or as a naturalized population outside its historic range due to massive habitat loss. Examples Examples of species and subspecies that are extinct in the wild include: *Alagoas curassow (last unconfirmed sighting reported in the late 1980s, listed extinct in the wild since 1994) *Beloribitsa * Cachorrito de charco palmal (last seen in 1994, listed extinct in the wild since 1996) * Christmas Island blue-tailed skink (listed extinct in the wild since 2014) *Dabry's sturgeon (listed extinct in the wild since 2022) * Escarpment cycad (listed extinct in the wild since 2006) *Franklinia (last seen in 1803, listed extinct in the wild since 1998) *Golden skiffia (listed extinct in the wild since 1996) *Guam kingfisher (listed extinct in the wild since 1986) *Hawaiian crow or ʻalalā (last seen in 2002, li ...

Paraguay
Paraguay (; ), officially the Republic of Paraguay ( es, República del Paraguay, links=no; gn, Tavakuairetã Paraguái, links=si), is a landlocked country in South America. It is bordered by Argentina to the south and southwest, Brazil to the east and northeast, and Bolivia to the northwest. It has a population of seven million, nearly three million of whom live in the capital and largest city of Asunción, and its surrounding metro. Although one of only two landlocked countries in South America (Bolivia is the other), Paraguay has ports on the Paraguay and Paraná rivers that give exit to the Atlantic Ocean, through the Paraná-Paraguay Waterway. Spanish conquistadores arrived in 1524, and in 1537, they established the city of Asunción, the first capital of the Governorate of the Río de la Plata. During the 17th century, Paraguay was the center of Jesuit missions, where the native Guaraní people were converted to Christianity and introduced to European culture. ...
