Energetic costs of sex reversal in lizards: implications for understanding evolutionary transitions between environmental and genotypic sex determination

Our aims are to understand patterns of energy turnover, growth and growth costs in both wild and labreared animals of different genetic/phenotypic sex to better understand the metabolic consequences of sex-reversal in two model systems with different patterns of GSD, Bassiana duperryii [XX (female): XY (male)] and Pogona vitticeps [ZW (female): ZZ (male)]. These are ideal systems as we already have sex-markers developed and a great deal of prior knowledge on the frequencies and abundances of sex-reversal in the wild. We will test the following questions
