The Adelaide pygmy blue-tongue skink (Tiliqua adelaidensis ), or pygmy bluetongue, is a species of skink, a lizard in the family Scincidae. The species was previously thought to be extinct and only rediscovered in 1992. Known locations of the species extend from Kapunda in the Light River valley, about 77 kilometres (48 mi) north east of Adelaide, northwards to Peterborough, about 254 kilometres (158 mi) north of Adelaide.
When artificial burrows were offered in the field to T. adelaidensis lizards, all the lizards preferred vertical rather than angled burrows and juvenile lizards preferred more shallow burrows than did adult lizards. Observation of 36 artificial burrows showed a significant increase in lizard numbers during 2001–2002 and over three surveys. The study suggests that this local increase in population could be due to lizards locating appropriate burrows much easier. The study results suggest that artificial burrows could be a tool for conservation management of this species.Show More
Another study compared the fitness of female lizards in natural burrows and artificial ones, over a three-year period. The study showed that the female in the artificial burrows had a better body condition, and produced larger offspring with better body conditions.Show Less
