Bibimys
''Bibimys'' is a genus of new world rats. Commonly known as the crimson-nosed rats, there are three species: *'' Bibimys chacoensis'' - Chaco crimson-nosed rat - found in north-east Argentina and Paraguay *'' Bibimys labiosus'' - Large-lipped crimson-nosed rat - south-east Brazil *'' Bibimys torresi'' - Torres's crimson-nosed rat - central Argentina Argentina (), officially the Argentine Republic ( es, link=no, República Argentina), is a country in the southern half of South America. Argentina covers an area of , making it the second-largest country in South America after Brazil, t ... A extinct species '' Bibimys massoiai'' is known from Quaternary remains in northeastern Brazil. Presently, species of ''Bibimys'' are found in Argentina, Brazil and Paraguay. As with most of the species in the South American Sigmodontinae, ''Bibimys'' has been arranged as a genus based mainly on morphological differences from the other living genera. ''Bibimys'' belongs to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bibimys Chacoensis
''Bibimys chacoensis'' is a species of small rodent of the family Cricetidae living in the north-central part of Southern Cone of South America. The common name of this species is Chaco crimson-nosed rat (in Spanish: ''ratón de hocico rosado norteño'' orthern pink-nosed mouse. It is one of the three species currently recognized under the genus ''Bibimys''. The species was described in 1931 by zoologist Harold H. Shamel, under the denomination of ''Akodon chacoensis''. The etymology of this species is a toponym for the locality where the type material was collected, Chaco Province in Argentina. The exact locality in the label is: “Las Palmas, provincia del Chaco, Argentina”. In 1980, Argentinian mammalogist, Elio Massoia, transferred it to genus ''Bibimys''. ''Bibimys chacoensis'' is considered to be an endemic species of the gallery forests and open spaces of the Humid Chaco region between the provinces of Formosa Province, Chaco, and Misiones Province. It has been also re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

New World Rat
The New World rats and mice are a group of related rodents found in North and South America. They are extremely diverse in appearance and ecology, ranging in from the tiny '' Baiomys'' to the large ''Kunsia''. They represent one of the few examples of muroid rodents (along with the voles) in North America, and the only example of muroid rodents to have made it into South America. The New World rats and mice are often considered part of a single subfamily, Sigmodontinae, but the recent trend among muroid taxonomists is to recognize three separate subfamilies. This strategy better represents the extreme diversity of species numbers and ecological types. Some molecular phylogenetic studies have suggested that the New World rats and mice are not a monophyletic group, but this is yet to be confirmed. Their closest relatives are clearly the hamsters and voles. The New World rats and mice are divided into 3 subfamilies, 12 tribes, and 84 genera. Classification *Family Cricetidae ...

Pleistocene
The Pleistocene ( , often referred to as the '' Ice age'') is the geological epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing a faunal interchange between the t ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

Argentina
Argentina (), officially the Argentine Republic ( es, link=no, República Argentina), is a country in the southern half of South America. Argentina covers an area of , making it the second-largest country in South America after Brazil, the fourth-largest country in the Americas, and the eighth-largest country in the world. It shares the bulk of the Southern Cone with Chile to the west, and is also bordered by Bolivia and Paraguay to the north, Brazil to the northeast, Uruguay and the South Atlantic Ocean to the east, and the Drake Passage to the south. Argentina is a federal state subdivided into twenty-three provinces, and one autonomous city, which is the federal capital and largest city of the nation, Buenos Aires. The provinces and the capital have their own constitutions, but exist under a federal system. Argentina claims sovereignty over the Falkland Islands, South Georgia and the South Sandwich Islands, and a part of Antarctica. The earliest recorded ...

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 city, 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 River, Paraguay and Paraná River, 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 Reductions, Jesuit missions, where the native Guaraní people were converted to Ch ...

Brazil
Brazil ( pt, Brasil; ), officially the Federative Republic of Brazil (Portuguese: ), is the largest country in both South America and Latin America. At and with over 217 million people, Brazil is the world's fifth-largest country by area and the seventh most populous. Its capital is Brasília, and its most populous city is São Paulo.

Quaternary
The Quaternary ( ) is the current and most recent of the three period (geology), periods of the Cenozoic era (geology), Era in the geologic time scale of the International Commission on Stratigraphy (ICS). It follows the Neogene Period and spans from 2.58 million years ago to the present. The Quaternary Period is divided into two epochs: the Pleistocene (2.58 million years ago to 11.7 thousand years ago) and the Holocene (11.7 thousand years ago to today, although a third epoch, the Anthropocene, has been proposed but is not yet officially recognised by the ICS). The Quaternary Period is typically defined by the cyclic growth and decay of continental ice sheets related to the Milankovitch cycles and the associated climate and environmental changes that they caused. Research history In 1759 Giovanni Arduino (geologist), Giovanni Arduino proposed that the geological strata of northern Italy could be divided into four successive formations or "orders" ( it, quattro ord ...
