Colour vision and polarisation systems in invertebrates
Martin How, from University of Bristol in UK, will give at talk about "Polarization as an alternative to colour for contrast vision in invertebrates". More information about Martin How at the University of Bristol's web.
The ability to detect the polarization of light is widespread among invertebrates, many of which use this modality for well-studied orientation and navigation tasks. Less well understood is how the polarization of light can contribute to local contrast-based visual tasks, particularly in animals that have largely done-away with colour vision. Here I will present our ongoing research in this area, with focus on the polarization vision of crustaceans and cephalopod molluscs.
