Genetic conservation in captive populations and endangered species

摘要: Many rare and endangered species require genetic conservation strategies involving an ex situ management phase prior to their reintroduction in nature. Since small populations are likely lose variation suffer from inbreeding depression, these designed terms monitor avoid effects as short-term goals, retain reestablishment or adaptive potential nature the long-term goal. Population theory helps us define concepts of effective population size, subdivision, discuss changes homozygosis, variance, fitness populations. Estimates several parameters models presented for three examples (Cheetah, Przewalski’s horse, Speke’s gazelle). Intermatings among different bred captivity conserved natural habitats can be guided (but not exactly prescribed) by migration, mating systems, drift. Rates level monitored drastic losses, thereby evolving tolerance certain amount inbreeding. These methods supplement never substitute conservation.
