Asháninka Arboreal Chinchilla Rat
The Asháninka arboreal chinchilla rat (''Cuscomys ashaninka'') is a large species of chinchilla rats from the Andes of far northern Cusco in Peru. It was first scientifically described in 1999. The first specimen of this species was discovered by Louise Emmons, a researcher of the Smithsonian Institution from Washington, D.C., who found it by chance while climbing in the Vilcabamba Mountains near Machu Picchu. Emmons named the genus after the city of Cusco, and she named the species for the Asháninka people who live in Peru. Description and habitat The animal has grey fur, with a white nose and lips, large claws, and a line of white fur running down its head. It is in length, with a tail of . It weighs . Ashaninka arboreal chinchilla rats live in dwarf forest and are hunted by long-tailed weasels. Classification When described, it was placed in the family Abrocomidae, but was considered different enough from existing species for the creation of the genus ''Cuscomys''. Sin ...

Chinchilla Rat
Chinchilla rats or ''chinchillones'' are members of the family Abrocomidae. This family has few members compared to most rodent families, with only nine known living species. They resemble chinchillas in appearance, with a similar soft fur and silvery-grey color, but have a body structure more like a short-tailed rat. They are social, tunnel-dwelling animals, and live in the Andes Mountains of South America. They are probably herbivorous, although this is not clear. They can be described as medium-sized. Stiff hairs project over the three middle digits of the rear feet. Their massive skulls narrow in the facial areas. Some molecular work suggests that, despite their appearance, they may be more closely related to octodontoids such as degus, nutria, and tuco-tucos than they are to chinchillas and viscachas. Etymology The family name is derived from the Ancient Greek word ἁβροκόμης (''habrokomēs'', "with delicate hair"). The word ἁβρός (habros) means "delicate ...

Long-tailed Weasel
The long-tailed weasel (''Neogale frenata''), also known as the bridled weasel, masked ermine, or big stoat, is a species of mustelid distributed from southern Canada throughout all the United States and Mexico, southward through all of Central America and into northern South America. It is distinct from the short-tailed weasel (''Mustela erminea''), also known as a "stoat", a close relation in the genus '' Mustela'' that originated in Eurasia and crossed into North America some half million years ago; the two species are visually similar, especially the black tail tip. Taxonomy Originally described in the genus '' Mustela'', a 2021 study reclassified it into the genus ''Neogale'' along with 2 other former ''Mustela'' species, as well as the two species formerly classified in '' Neovison''. Evolution The long-tailed weasel is the product of a process begun 5–7 million years ago, when northern forests were replaced by open grassland, thus prompting an explosive evolution of ...

Mammals Of Peru
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla ( hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla (cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, toge ...

Cuscomys
''Cuscomys'' is a genus of rodents found in the Andes of Cusco in southern Peru. These relatively large chinchilla rats are dark grey with a distinct white line running from the crown to the nose. The genus was coined in 1999 when ''C. ashaninka'' was scientifically described,Emmons, L. H. (1999). ''A new genus and species of abrocomid rodent from Peru (Rodentia: Abrocomidae).'' American Museum Novitates 3279: 1-14. but later it was discovered that ''C. oblativus'', a species traditionally placed in the genus ''Abrocoma'', actually belonged in ''Cuscomys''. They are very poorly known, as ''C. ashaninka'' only is known from the holotype, while ''C. oblativus'' usually has been considered extinct, as it was only known from remains found in 1912, buried alongside people in ancient Inca tombs at the Machu Picchu ruins. However, photos of a rodent taken at the ruins in late 2009 likely show this species.Castillo, G. M. (2009). Detectan en Cusco a roedor declarado extinto'. El Comercio ...

IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. 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 partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinct
Extinction is the termination of a kind of organism or of a group of kinds ( taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abrocoma
''Abrocoma'' is a genus of abrocomid rodents found in the Andes of South America, from southern Peru to central Chile. The genus contains eight species, most of which are found in isolated mountain ranges in northwestern Argentina. The oldest fossil record for the Caviomorpha appears at the late Eocene-Early Oligocene transition (37.5–31.5 mybp). Species *Genus ''Abrocoma'' **''A. bennettii'' - Bennett's chinchilla rat **''A. boliviensis'' - Bolivian chinchilla rat **''A. budini'' - Budin's chinchilla rat **''A. cinerea'' - ashy chinchilla rat **''A. famatina'' - Famatina chinchilla rat **''A. shistacea'' - Sierra del Tontal chinchilla rat **''A. uspallata'' - Uspallata chinchilla rat **''A. vaccarum'' - Punta de Vacas chinchilla rat or Mendozan chinchilla rat Additionally, the species ''Cuscomys oblativus The Machu Picchu arboreal chinchilla rat (''Cuscomys oblativus'') is a large species of South American chinchilla rats, known from skeletal remains found by memb ...

Cuscomys Oblativus
The Machu Picchu arboreal chinchilla rat (''Cuscomys oblativus'') is a large species of South American chinchilla rats, known from skeletal remains found by members of the Peruvian Expedition of 1912. The animals were buried alongside people in ancient Inca tombs at Machu Picchu in Peru. It was considered extinct by the IUCN in 2008, but conservation status was changed to data deficient in 2016. Photos of a rodent taken at Machu Picchu in late 2009 likely show this species, a finding apparently confirmed in 2014. In 2020, as part of biodiversity study, a report was released with images that captured the rodent in the surroundings of Machu Picchu sanctuary. Originally assigned to the genus ''Abrocoma'', recent studies showed it to be more closely allied to ''Cuscomys ashaninka ''Cuscomys'' is a genus of rodents found in the Andes of Cusco in southern Peru.

Dwarf Forest
Dwarf forest, elfin forest, or pygmy forest is an uncommon ecosystem featuring miniature trees, inhabited by small species of fauna such as rodents and lizards. They are usually located at high elevations, under conditions of sufficient air humidity but poor soil. There are two main dwarf forest ecosystem types, involving different species and environmental characteristics: coastal Temperate climate, temperate and Montane ecology, montane tropical regions. Temperate coastal dwarf forest is common for parts of Southern California. Montane tropical forests are found across tropical highlands of Central America, northern South America and Southeast Asia. There are also other isolated examples of dwarf forests scattered across the world, while the largest dwarf forest is found in the Philippines. High-elevation tropical dwarf forest High-elevation tropical locations in cloud forests contain mossy wet elfin forests due to high-elevation precipitation. These regions are characterized ...

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 mountain ra ...

Asháninka
The Asháninka or Asháninca are an indigenous people living in the rainforests of Peru and in the State of Acre, Brazil. Their ancestral lands are in the forests of Junín, Pasco, Huánuco and part of Ucayali in Peru. Population The Asháninka are estimated between 25,000 and 10,000,000, although others give 88,000 to almost 100,000. Only little more than a thousand of them live on the Brazilian side of the border. The Ashaninka communities are scattered throughout the central rainforests of Peru in the Provinces of Junin, Pasco, Huanuco, a part of Ucayali, and the Brazilian state of Acre. Subsistence The Asháninka are mostly dependent on subsistence agriculture. They use the slash-and-burn method to clear lands and to plant yucca roots, sweet potato, corn, bananas, rice, coffee, cacao and sugar cane in biodiversity-friendly techniques. They live from hunting and fishing, primarily using bows and arrows or spears, as well as from collecting fruit and vegetables in the j ...
