Sternarchogiton Zuanoni
''Sternarchogiton zuanoni'' is a species of weakly electric, freshwater ray-finned fish belonging to the family Apteronotidae, the ghost knifefishes. This species is known only from a single locality in Brazil. Taxonomy ''Sternarchogiton zuanoni'' was first formally described in 2010 by the Bazilian ichthyologist Carlos David de Santana and the American ichthyologist Richard P. Vari with its type locality given as the Rio Xingu, Município de Altamira, Cachoeira de Kaituká at 3°12'S, 52°12'W in Pará. The genus ''Sternarchogiton'' is classified within the subfamily Aperonotinae of the family Aperonotidae, the ghost kinfefishes. Etymology ''Sternarchogiton zuanoni'' is classified in the genus ''Sternarchogiton'', a name which combines ''Sternarus'', a synonym of ''Apteronotus'', with ''geiton'', which means neighbour. ''Sternarus'' was the genus that the type species of ''Sternarchogiton'', '' S. nattereri'' was originally placed in, thus the name means "neighbour of Ster ...

Synonym (taxonomy)
In taxonomy, the scientific classification of living organisms, a synonym is an alternative scientific name for the accepted scientific name of a taxon. The Botanical nomenclature, botanical and Zoological nomenclature, zoological codes of nomenclature treat the concept of synonymy differently. * In nomenclature, botanical nomenclature, a synonym is a Binomial nomenclature, scientific name that applies to a taxon that now goes by a different scientific name. For example, Carl Linnaeus, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different Binomial nomenclature, binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Critically Endangered
An IUCN Red List critically endangered (CR or sometimes CE) species is one that has been categorized by the International Union for Conservation of Nature as facing an extremely high risk of extinction in the wild. As of December 2023, of the 157,190 species currently on the IUCN Red List, 9,760 of those are listed as critically endangered, with 1,302 being possibly extinct and 67 possibly extinct in the wild. The IUCN Red List provides the public with information regarding the conservation status of animal, fungi, and plant species. It divides various species into seven different categories of conservation that are based on habitat range, population size, habitat, threats, etc. Each category represents a different level of global extinction risk. Species that are considered to be critically endangered are placed within the "Threatened" category. As the IUCN Red List does not consider a species extinct until extensive targeted surveys have been conducted, species that a ...

Vulnerable Species
A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. In 2012 there were 5,196 animals and 6,789 plants classified as vulnerable, compared with 2,815 and 3,222, respectively, in 1998. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A taxon ...

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partners ...

Belo Monte Dam
The Belo Monte Dam (''formerly known as'' Kararaô) is a hydroelectric dam complex on the northern part of the Xingu River in the state of Pará, Brazil. After its completion, with the installation of its 18th turbine, in November 2019, the installed capacity of the dam complex is 11,233 megawatts (MW), which makes it the second largest hydroelectric dam complex in Brazil and the fifth largest in the world by installed capacity, behind the Three Gorges Dam, Baihetan Dam and the Xiluodu Dam in China and the Brazilian-Paraguayan Itaipu Dam. Considering the oscillations of river flow, guaranteed minimum capacity generation from the Belo Monte Dam would measure 4,571 MW, 39% of its maximum capacity. Brazil's rapid economic growth over the last decade has provoked a huge demand for new and stable sources of energy, especially to supply its growing industries. In Brazil, hydroelectric power plants produce over 66% of the electrical energy. The Government has decided to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holotype
A holotype (Latin: ''holotypus'') is a single physical example (or illustration) of an organism used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany and mycology, an isotype is a duplicate of the holotype, generally pieces from the same individual plant or samples from the same genetic individual. A holotype is not necessarily "ty ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet, species epithet, or epitheton) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Etymology Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the ...

Sternarchogiton Nattereri
''Sternarchogiton nattereri'' is a species of weakly electric fish, weakly electric Gymnotiformes, knifefish in the family Apteronotidae. It is native to the Amazon basin, Amazon River system and feeds on sponges. Unlike other members of the genus ''Sternarchogiton'', there is pronounced sexual dimorphism in ''S. nattereri'', with reproductively mature males developing strong external teeth on tips of their jaws. These males are so different from the females and juvenile (organism), juveniles that they were thought to be a different genus and species, the "tooth-lip knifefish" ''Oedemognathus exodon'', for over 40 years. Distribution and habitat ''S. nattereri'' is restricted to large river channels in the lowlands of the Amazon basin. Its habitat ranges from high-Electrical conductivity, conductivity, sediment-rich Whitewater river (river type), whitewater rivers such as the Rio Solimões, to low-conductivity, sediment-poor blackwater river, blackwaters such as the Rio Negro (Ama ...
