Population genetics and the effects of a severe bottleneck in an ex situ population of critically endangered Hawaiian tree snails.

PloS one - 1 Jan 2014

Abstract excerpt

As wild populations decline, ex situ propagation provides a potential bank of genetic diversity and a hedge against extinction. These programs are unlikely to succeed if captive populations do not recover from the severe bottleneck imposed when they are founded with a limited number of individuals from remnant populations. In small captive populations allelic richness may be lost due to genetic drift, leading to...
