Mechanisms of colour production and the evolution of animal signals

Grant number: DP150101044 | Funding period: 2015 - 2018



This project aims to reveal how diverse colours are produced in reptiles and the information these colours convey about individual health, condition and performance. The project evaluates how stress affects both pigment deposition and the nano-structure of cells and tissues, which together produce colour. By comparing similar colours generated by two entirely different classes of pigment (carotenoids and pteridines), this project will provide new insights into the evolution of animal coloration, and will significantly enhance our understanding of pteridines, one of the most prevalent but least understood classes of pigment in vertebrates.
