Conservation genetics and ecological modelling of the Tjakura (Liopholis kintorei).

Low genetic variation increases extinction risk through inbreeding depression and loss of adaptive potential. Translocating Tjakura to supplement the population size and genetic variation in dwindling populations is being considered by conservation managers. Effective implementation of these projects requires measures of genetic variation and local adaptation to identify at-risk populations and suitable donor populations. We aim to characterize genetic variation and patterns of localised adaptation, identifying genetically depauperate populations and suitable donor populations for translocation and genetic rescue. Additionally, genetic data will be incorporated into predictive viability and distribution models, proactively informing management under future environmental/ecological conditions.

We aim to understand the underlying genetics of populations of great desert skink across their range, assessing both contemporary measures of population genetics as well as changes over time. Results of these analyses will inform translocation projects moving forward in order to maintain healthy populations of Tjakura across their ranges, with the aim of conserving this culturally significant species. Genetics information will also be assessed in relation to the environment, particularly climate, fire regimes and feral species in order to predict best management strategies into the future.
