Variation in pigmentation often underlies many tractable and interesting questions in evolutionary biology; such as speciation, adaptation and sexual selection. In the zebra finch we have identified candidate genes for red beak colouration. Click here to read more

Ultraviolet signalling in flat lizards, Platysaurus broadleyi


Male competition is a driving force in the evolution and exaggeration of male traits and colourful male badges are a striking example of this. Ultraviolet (UV) colour badges are an interesting example of colourful signals that while invisible to us are used extensively in a range of other taxa. We investigated how UV signals were used during male contests in the Augrabies flat lizard. Click here to read more
