Limnomedusa (genus)
''Limnomedusa macroglossa'' (common name: rapids frog) is a species of frog in the family Alsodidae, in the monotypic genus ''Limnomedusa''. It is found in southern Brazil, northeastern Argentina, Uruguay, and northern Paraguay. ''Limnomedusa macroglossa'' are found in open and forested areas on rocky soil along rivers. Tadpoles are found in temporary river-side pools and slow-flowing water. It is threatened by habitat degradation due to agricultural activities, water pollution, hydroelectric development, and pine plantations. For example, the Itaipu Dam The Itaipu Dam ( pt, Barragem de Itaipu , es, Represa de Itaipú ) is a hydroelectric dam on the Paraná River located on the border between Brazil and Paraguay.

Leopold Fitzinger
Leopold Joseph Franz Johann Fitzinger (13 April 1802 – 20 September 1884) was an Austrian zoologist. Fitzinger was born in Vienna and studied botany at the University of Vienna under Nikolaus Joseph von Jacquin. He worked at the Vienna Naturhistorisches Museum between 1817, when he joined as a volunteer assistant, and 1821, when he left to become secretary to the provincial legislature of Lower Austria; after a hiatus he was appointed assistant curator in 1844 and remained at the Naturhistorisches Museum until 1861. Later he became director of the zoos of Munich and Budapest. In 1826 he published ''Neue Classification der Reptilien'', based partly on the work of his friends Friedrich Wilhelm Hemprich and Heinrich Boie. In 1843 he published ''Systema Reptilium'', covering geckos, chameleons and iguanas. Fitzinger is commemorated in the scientific names of five reptiles: '' Algyroides fitzingeri'', '' Leptotyphlops fitzingeri'', '' Liolaemus fitzingerii'', ''Micrurus tener fitzi ...

Itaipu Dam
The Itaipu Dam ( pt, Barragem de Itaipu , es, Represa de Itaipú ) is a hydroelectric dam on the Paraná River located on the border between Brazil and Paraguay. The construction of the dam was first contested by Argentina, but the negotiations and resolution of the dispute ended up setting the basis for Argentine–Brazilian integration later on. The name "Itaipu" was taken from an isle that existed near the construction site. In the Guarani language, means "the sounding stone". The Itaipu Dam's hydroelectric power plant produced the second-most electricity of any in the world as of 2020, only surpassed by the Three Gorges Dam plant in electricity production. Completed in 1984, it is a binational undertaking run by Brazil and Paraguay at the border between the two countries, north of the Friendship Bridge. The project ranges from Foz do Iguaçu, in Brazil, and Ciudad del Este in Paraguay, in the south to Guaíra and Salto del Guairá in the north. The installed generation ...

Amphibians Of Paraguay
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic ...

Taxa Named By Gabriel Bibron
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ...

Paraná (state)
Paraná () is one of the 26 states of Brazil, in the south of the country, bordered on the north by São Paulo state, on the east by the Atlantic Ocean, on the south by Santa Catarina state and the province of Misiones, Argentina, and on the west by Mato Grosso do Sul and Paraguay, with the Paraná River as its western boundary line. It is subdivided into 399 municipalities, and its capital is the city of Curitiba. Other major cities are Londrina, Maringá, Ponta Grossa, Cascavel, São José dos Pinhais and Foz do Iguaçu. The state is home to 5.4% of the Brazilian population and has 6.2% of the Brazilian GDP. Crossed by the Tropic of Capricorn, Paraná has what is left of the araucaria forest, one of the most important subtropical forests in the world. At the border with Argentina is the National Park of Iguaçu, considered by UNESCO as a World Heritage Site. At only from there, at the border with Paraguay, the largest dam in the world was built, the Hidroelétrica de Itaipu ...

Habitat Degradation
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, intro ...

André Marie Constant Duméril
André Marie Constant Duméril (1 January 1774 – 14 August 1860) was a French zoologist. He was professor of anatomy at the Muséum national d'histoire naturelle from 1801 to 1812, when he became professor of herpetology and ichthyology. His son Auguste Duméril was also a zoologist. Life André Marie Constant Duméril was born on 1 January 1774 in Amiens and died on 14 August 1860 in Paris. He became a doctor at a young age, obtaining, at 19 years, the ''prévot'' of anatomy at the medical school of Rouen. In 1800, he left for Paris and collaborated in the drafting of the comparative anatomy lessons of Georges Cuvier. He replaced Cuvier at the Central School of the Panthéon and had, as his colleague, Alexandre Brongniart. In 1801, he gave courses to the medical school of Paris. Under the ''Restauration'', he was elected a member of the Académie des Sciences (French Academy of Sciences) and after 1803 succeeded Lacépède, who was occupied by his political offic ...

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. ...
