Abstract

Reptiles are the most diverse vertebrate group. Their successful conquering of a great variety of ecological niches has been accompanied by the extensive evolutionary radiation of their visual system. This thesis applies a comparative approach to investigate the visual abilities of key species of Australian reptiles across different ecological niches. Microspectrophotometry, electrophysiology and stereology are used to investigate colour vision and the spatial distribution of retinal neurons. The results provide detailed information about the visual capabilities of several iconic Australian species and can be used to understand past evolutionary pressures as well as future conservation needs.
