Investigating motion-based communication in agamid lizards and how it is affected by habitat structure
Signal diversity in lizard displays relates to habitat structure, with differences in signal complexity between species influenced by a variety of ecological factors. Much of our knowledge about movement-based lizard signals has come from the iguanids of North/South America. Surprisingly, the agamid lizards of Australia have received comparatively little attention despite the prevalence of motor patterns in their social behaviour. I intend to quantify the movement-based signals of several agamid species using an innovative approach that ensures signals are captured in three-dimensions. I will also relate habitat characteristics to the structure of these displays to provide a better understanding on how habitat changes might reflect on signalling efficiency.
