Success
In 1971 the de Wildt Cheetah and Wildlife Centre was established. Between 1975 and 2005, 242 litters were born with a total of 785 cubs. In a study done by Bertschinger, H. J., Meltzer, D. J. A., & Van Dyk, A. (2008), the survival rate of cubs was examined. "Mean cub survival from 1 to 12 months and greater than 12 months of age was 71.3 and 66.2%, respectively." This study shows that cheetahs can be bred successfully and that their endangerment can be decreased through these breeding programs. It also indicated that failure in other breeding habitats may be due to "poor" sperm morphology.
Recently, the number of wild Tasmanian devils is declining from transmissible Devil Facial Tumor Disease. A captive insurance population program has started, but the captive breeding rates at the moment are lower than they need to be. A study done by Keeley, T. J., O, J. K., Fanson, B. G., Masters, K., and McGreevy, P. D. (2012), had a goal to "increase our understanding of the estrous cycle of the devil and elucidate potential causes of failed male-female pairings." The temporal patterns of fecal progestogen and corticosterone metabolite concentrations were examined. A big finding in this study is that the majority of unsuccessful females were mostly captive born. This is important because if there were no wild Tasmanian devils left and their survival relied solely on captive breeding, the population would probably disappear.

Famous quotes containing the word success:
“If A is a success in life, then A equals x plus y plus z. Work is x; y is play; and z is keeping your mouth shut.”
—Albert Einstein (1879–1955)
“It’s not a field, I think, for people who need to have success every day: if you can’t live with a nightly sort of disaster, you should get out. I wouldn’t describe myself as lacking in confidence, but I would just say that ... the ghosts you chase you never catch.”
—John Malkovich (b. 1953)
“Men of extraordinary success, in their honest moments, have always sung, “Not unto us, not unto us.” According to the faith of their times, they have built altars to Fortune, or to Destiny, or to St. Julian. Their success lay in their parallelism to the course of thought, which found in them an unobstructed channel; and the wonders of which they were the visible conductors seemed to their eye their deed.”
—Ralph Waldo Emerson (1803–1882)
