Conservation genetics of threatened Mexican axolotls (Ambystoma)

The loss of genetic diversity in small or isolated populations can increase inbreeding, decrease fitness and adaptive potential and increase a species’ probability of extinction. In species with life histories that naturally result in small populations and/or low levels of gene flow, patterns of anthropogenically induced genetic erosion can be obscured by evolutionary history; yet these species may still be susceptible to genetic loss.
