Can captive breeding have deleterious effects on individual fitness?
A study of a population of Mauritius kestrels Falco punctatus in eastern Mauritius (Ewing et al. 2008) found that the population had grown from 12 individuals in 1987 to a minimum of 154 by 2002. Over this time, the degree of inbreeding increased by 2.6% each generation and by 2002, 25% of pairs were either closely or moderately related. Over this period 1.6% of genetic diversity was lost each generation. Effects on reproduction or survival were not monitored.
