Co-evolution of colour vision and coloration in colourful songbirds
Supervisor: Dr Nick Mundy
The project will investigate whether sexual selection on bright red and yellow coloration in birds is reflected in evolution of colour vision. This will be achieved by examining evolution and expression of major genes involved in two components of colour vision, the opsin photopigments and coloured oil droplets. The main study system is the ploceid finches, which have large variation in carotenoid-based sexually selected plumage coloration, from red to yellow to an absence of bright coloration.
What the student will be doing:
The main component is labwork to sequence and quantify expression in the target genes. There will be some fieldwork in Africa to collect samples, and an opportunity to do some colour vision modelling.
