Prairie dogs were targeted as pests because their burrows damaged farm implements and tractors.In addition, the prairie dogs appear to have suffered from introduction of plague.This is characteristic of animals whose recent ancestors have been through a catastrophic drop in population in the relatively recent past.This lack of genetic diversity frustrates conservation workers who must work not only to breed the cheetah population back up to safe numbers, but avoid further inbreeding in the process.Ferrets also suffered from habitat fragmentation as the plains were developed for agricultural and other purposes.By 1985, the species was limited to ~10 individuals in two populations (South Dakota and Wyoming).

If the wild cheetah is to be saved, conservation efforts must focus on breeding the cats back from the edge of extinction with special care.In general, only the information that you provide, or the choices you make while visiting a web site, can be stored in a cookie.For example, the site cannot determine your email name unless you choose to type it.This research, done by an international team and published in Genome Biology, uses whole-genome sequencing to establish not one, but two major bottlenecks in the cheetahs’ history.The first, dating to around 100,000 years ago, came when a small founder population of cheetahs broke away from American pumas and migrated to Asia.
