Abstract:
Abstract 10.1002/(SICI)1098-2361(1997)16:1<9::AID-ZOO3>3.3.CO;2-J In a review of the evidence for reduction in the severity of inbreeding depression in Speke’s gazelle [Templeton and Read, pp. 241–261 in Genetics and Conservation: A Reference for Managing Wild Animal and Plant Populations, C.M. Schoenwald-Cox, S.M. Chambers, B. MacBryde, and L. Thomas, eds., Reading, MA, Addison-Weley, 1983; Templeton and Read, Zoo Biology 3:177–199, 1984] a flaw was found in the statistical analysis. Reanalysis of the 1983 data showed no significant reduction in the severity of inbreeding depression. An updated analysis using data from the 1992 Speke’s Gazelle North American Regional Studbook [Fischer, St. Louis, St. Louis Zoological Park, 1993] also showed no significant reduction in the severity of inbreeding depression. While there is empirical evidence suggesting reduction in the severity of inbreeding depression in captive populations is possible through reduction of the founder base, maintenance of genetic variation must remain the primary goal of genetic management strategies for captive populations of exotic wildlife.
