摘要

The Lancelin Island skink was first discovered in 1961 and recognised as a distinct species in 1972.The species was named Ctenotus lancelini after its island home, following genetic research that differentiated it from the red-legged skink (Ctenotus labillardieri). The small threatened lizard was once only known from the 7.5-hectare Lancelin Island and one site on the adjacent mainland. However, six years ago individuals bred at Perth Zoo were translocated to Favorite Island, approximately 200 kilometres north of Perth. This move made the skink one of only a handful of reptiles to be translocated for conservation purposes anywhere in the world. Since the species was restricted to one population, the chances of extinction due to some disturbance, such as the introduction of exotic animals or fire, were considerable. Genetic diversity is likely to be limited by its small population size, so the skink may be less equipped to cope with factors such as climate change. Therefore, a translocation provides a 'backup' population should there be any detrimental impact on the natural population.
