The Chinchilla, How endangered are in Chile?

 Surprisingly since surely many of you have had a home chinchilla, chinchillas wild 'parents' of domestic chinchillas, are critically endangered.

Reasons?: In just 15 years in Chile has gone to 90% of its population, plus the very low current population is under pressure from poaching and habitat reduction? reason enough to classify it as seriously endangered.
To make it more clear to us, these chinchillas were once abundant, but came to have only 42 small colonies in the wild in 1996. The number of these colonies and the general population size decreases steadily in time.

Although lower quality of coat and size as the other Chinchilla, has established worldwide market, probably because of its greater malleability in captivity.

 A long-tailed chinchilla (Chinchilla lanigera), also called chinchilla Chilean coastal chinchilla, Chinchilla chinchilla costina or less.

COMPARISON Chinchillas: Chinchilla Within the genus there are two species, the long-tailed Chinchilla and actual chinchilla (Chinchilla chinchilla), formerly known as Chinchilla brevicaudata. Both are in critical danger of extinction. In comparison, the long-tailed Chinchilla is smaller, has more rounded ears and tail longer than the actual chinchilla.
Domestic Copies are larger than wild and have more sexual dimorphism, which means that there are more differences between males and females. There are also more varieties of colors due to mutations that have been maintained through artificial selection. Keep in mind that the first copies to play them and raise them in captivity were not chosen at random, if that were not selected for the quality of their hair and their size. Until now point are different, they are not considered the same species, so obviously not feel threatened.

THREATS

1.Actualmente are so few, that are below the minimum viable population, that is, there are not enough copies so that populations are maintained for long. To give us an idea, say for example if there are 10 pieces in a very large, are not and do not reproduce? This would be an example that can happen in a non viable.
2.the predation by foxes has increased in recent years, probably because they are also scarce other usual prey for the fox.
3.On recently, the decline is exacerbated by both abiotic and biotic changes
4.Many species populations increase and decrease in their cycles (increase and decrease very much increase again?) Could be that they are in a phase of decline in population
5.Peleterias: Legal who are over Chile which produces a threat to this species.
