Chinchillas
Chinchillas are either of two species (''Chinchilla chinchilla'' and ''Chinchilla lanigera'') of crepuscular rodents of the parvorder Caviomorpha. They are slightly larger and more robust than ground squirrels, and are native to the Andes mountains in South America. They live in colonies called "herds" at high elevations up to . Historically, chinchillas lived in an area that included parts of Bolivia, Peru, Argentina, and Chile, but today, colonies in the wild are known only in Chile. Along with their relatives, viscachas, they make up the family Chinchillidae. They are also related to the chinchilla rat. The chinchilla has the densest fur of all mammals that live on land. In the water, the sea otter has a denser coat. The chinchilla is named after the Chincha people of the Andes, who once wore its dense, velvet-like fur. By the end of the 19th century, chinchillas had become quite rare after being hunted for their ultra-soft fur. Most chinchillas currently used by the fur indu ...

Chinchilla Chinchilla
The short-tailed chinchilla (''Chinchilla chinchilla)'' is a small rodent part of the Chinchillidae family and is classified as an endangered species by the International Union for Conservation of Nature, IUCN. Originating in South America, the chinchilla is part of the genus ''Chinchilla'', which is separated into two species: the long-tailed chinchilla and the short-tailed chinchilla. Although the short-tailed chinchilla used to be found in Chile, Argentina, Peru, and Bolivia, the geographical distribution of the species has since shifted. Today, the species remains extant in the Andes mountains of northern Chile, but small populations have been found in southern Bolivia. The short-tailed chinchilla is characterized by its grayish-blue fur which is extremely dense and plush. The short-tailed chinchilla has a short furry tail, which distinguishes it from the long-tailed chinchilla. Compared to ''Long-tailed chinchilla, C. lanigera, C. chinchilla'' has smaller, more rounded ears and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chinchilla Lanigera
The long-tailed chinchilla (''Chinchilla lanigera''), also called the Chilean, coastal, common, or lesser chinchilla, is one of two species of rodent from the genus '' Chinchilla'': the other species being '' C. chinchilla''. Both species are endangered in the wild after historically being hunted for their soft hair coats. Domestic breeds of chinchilla are believed to descend from specimens of ''C. lanigera''. Domestic chinchillas come in three types: ''la plata, costina'', and ''raton''. Historically, Chilean chinchillas were reported from Talca (35°30’S), Chile, north to Peru, and also eastward, from Chilean coastal hills, throughout low mountains. No fossils of the Chilean chinchilla are known to have been found, and by the mid-19th century, Chilean chinchillas were not found south of the Choapa River in central Chile. Wild populations of Chilean chinchillas, as of 1996, occurred in Aucó (31°38’S, 71°06’W), near Illapel, IV Región, Chile, in Reserva Nacional Las Ch ...

Pocket Pet
The most common rodents kept as household pets are hamsters (golden hamsters and dwarf hamsters), gerbils (Mongolian jirds and duprasi gerbils), common degus, fancy mice, fancy rats, common chinchillas, and guinea pigs (cavies). The domestication of small mammals is a relatively recent development, arising only after large-scale industrialization. Historically, Western society was more agrarian than today, with rodents as a whole seen as vermin that were carriers for disease and a threat to crops. Animals that hunted such pests (e.g. terriers and cats) were prized. Some of these small rodents are prohibited from being kept as pets in certain areas for being invasive; California, Hawaii, and New Zealand have strict regulations to protect their native environments and agricultural operations. Gerbils, degus, and domesticated rats have various prohibitions on their ownership. Characteristics Guinea pig Guinea pigs (cavy) have perhaps been kept the longest as pets amon ...

Rodent
Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for New Zealand, Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/richochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and pikas, whose i ...

Chinchillidae
The family Chinchillidae is in the order Rodentia and consists of the chinchillas, the viscachas, and their fossil relatives. This family is restricted to southern and western South America, mostly living in mountainous regions of the Andes but one species living on plains. They are medium to large-sized rodents, weighing from to , with strong hind legs and large ears and a bushy tail. All species have thick, soft fur, which is considered valuable in some cultures. Characteristics Members of the family Chinchillidae are somewhat rabbit or squirrel-like rodents varying in weight from . They have large eyes, medium-sized ears, soft dense fur and short bushy tails. The forelegs are shorter than the hind legs. The forefeet have four toes while the hind feet have four small-clawed toes in ''Lagidium'' and ''Chinchilla'' but three large-clawed toes in '' Lagostomus'', a digging species. Their dental formula is and their incisors grow continually throughout their lives. Chinchillids a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fur Industry
Fur farming is the practice of breeding or raising certain types of animals for their fur. Most of the world's farmed fur is produced by European farmers. In 2018, there were 5,000 fur farms in the European Union, EU, all located across 22 countries; these areas of production collectively accounted for 50% of the global production of farmed fur. The EU accounts for 63% of global mink production and 70% of fox production. Denmark was the leading mink-producing country, accounting for approximately 28% of world production. The top three fur producers are Denmark (formerly), Poland and China. Finland is the largest United States supplier of fox pelts. The United States is a major exporter of fur skins. Major export markets include China, Russia, Canada, and the EU. Exports to Asia as a share of total exports grew from 22% in 1998 to 47% in 2002. As of 2012, Russia was reported to be the world's biggest sales market for fur. China has been the world's largest importer of fur pelts ...

Cerro De Pasco
Cerro de Pasco is a city in central Peru, located at the top of the Andean mountains. It is the capital of the Pasco region, and an important mining center. At elevation, it is one of the highest cities in the world, and the highest or the second highest city with over 50,000 inhabitants, with elevation reaching up to in the Yanacancha area. It is connected by road and by rail to the capital Lima, away. Mining center Cerro de Pasco became one of the world's richest silver producing areas after silver was discovered there in 1630. It is still an active mining center. The Spanish mined the rich Cerro de Pasco silver-bearing oxide ore deposits since colonial times. Sulfide minerals are more common in the Atacocha district however. Francisco Uville arranged for steam engines made by Richard Trevithick of Cornwall, England, to be installed in Cerro de Pasco in 1816 to pump water from the mines and allow lower levels to be reached.

Antofagasta Region
The Antofagasta Region ( es, Región de Antofagasta, ) is one of Chile's sixteen first-order administrative divisions. The second-largest region of Chile in area, it comprises three provinces, Antofagasta, El Loa and Tocopilla. It is bordered to the north by Tarapacá, by Atacama to the south, and to the east by Bolivia and Argentina. The region's capital is the port city of Antofagasta; another one of its important cities is Calama. The region's main economic activity is copper mining in its giant inland porphyry copper systems. Antofagasta's climate is extremely arid, albeit somewhat milder near the coast. Nearly all of the region is devoid of vegetation, except close to the Loa River and at oases such as San Pedro de Atacama. Much of the inland is covered by salt flats, tephra and lava flows, and the coast exhibits prominent cliffs. The region was sparsely populated by indigenous Changos and Atacameños until massive Chilean immigration in conjunction with a saltpeter ...

Jujuy Province
Jujuy is a province of Argentina, located in the extreme northwest of the country, at the borders with Chile and Bolivia. The only neighboring Argentine province is Salta to the east and south. Geography There are three main areas in Jujuy: *The Altiplano, a plateau high with peaks of , covers most of the province. *The Río Grande of Jujuy cuts through the Quebrada de Humahuaca canyon, of heights between . *To the southeast, the sierras descends to the Gran Chaco region. The vast difference in height and climate produces desert areas such as the Salinas Grandes salt mines and subtropical Yungas jungle. The terrain of the province is mainly arid and semi-desertic across the different areas, except for the ''El Ramal'' valley of the San Francisco River. Temperature difference between day and night is wider in higher lands, and precipitation is scarce outside the temperate area of the San Francisco River. The Grande River and the San Francisco River flow to the Bermejo River. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overexploitation
Overexploitation, also called overharvesting, refers to harvesting a renewable resource to the point of diminishing returns. Continued overexploitation can lead to the destruction of the resource, as it will be unable to replenish. The term applies to natural resources such as water aquifers, grazing pastures and forests, wild medicinal plants, fish stocks and other wildlife. In ecology, overexploitation describes one of the five main activities threatening global biodiversity. Ecologists use the term to describe populations that are harvested at an unsustainable rate, given their natural rates of mortality and capacities for reproduction. This can result in extinction at the population level and even extinction of whole species. In conservation biology, the term is usually used in the context of human economic activity that involves the taking of biological resources, or organisms, in larger numbers than their populations can withstand. The term is also used and defined some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Du Chinchilla Lanigera - Auco
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
