Dr Jim Barnett


I am interested in camouflage and aposematism, and how multiple selection pressures interact. I am interested in amphibian visual ecology, behaviour, and conservation.

My MSc and PhD focused on distance-dependent defensive colouration – patterns which are highly salient at close range but form effective camouflage when viewed from greater distances.

Research projects included distance-dependent colouration in the cinnabar moth caterpillar (Tyria jacobaeae Erebidae) and the dyeing poison frog (Dendrobates tinctorius Dendrobatidae), as well as the optimisation of camouflage in tropical toads (Rhinella margaritifera Bufonidae) and glass frogs (Teratohyla midas Centrolenidae).
