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:
“The white man regards the universe as a gigantic machine hurtling through time and space to its final destruction: individuals in it are but tiny organisms with private lives that lead to private deaths: personal power, success and fame are the absolute measures of values, the things to live for. This outlook on life divides the universe into a host of individual little entities which cannot help being in constant conflict thereby hastening the approach of the hour of their final destruction.”
—Policy statement, 1944, of the Youth League of the African National Congress. pt. 2, ch. 4, Fatima Meer, Higher than Hope (1988)
“The two-party system has given this country the war of Lyndon Johnson, the Watergate of Nixon, and the incompetence of Carter. Saying we should keep the two-party system simply because it is working is like saying the Titanic voyage was a success because a few people survived on life-rafts.”
—Eugene J. McCarthy (b. 1916)
“The I’m-going-to-win-no-matter-how-I-have-to-do-it attitude just doesn’t seem to fit. For me, a contest isn’t a success unless it was fun, whether or not I win.”
—Margo Godfrey Oberg (b. c. 1955)
