Effective Population Size and Creation

Today, perhaps the most well-known species that is falling off the extinction cliff is the cheetah. Scientists know that Cheetah viability is dropping, litter size is shrinking, and deformities are increasing. As Kelly (2001) pointed out, the effective population size in cheetahs is a mere fifteen percent of the actual population size, far below what is acceptable to maintain a species. The cheetah will go extinct and nothing can be done to prevent it.
