Seeing without eyes: the evolution of non-visual photoreceptors in vertebrates. Australia's underwater biodiversity is second to none with endemic species representing the earliest stages in vertebrate evolution, many of them relying heavily on vision for survival. Tracing the evolution of light detection and image formation will provide crucial information about the lifestyles of our vertebrate ancestors, the environmental selection pressures driving speciation and colour communication. Charact ....Seeing without eyes: the evolution of non-visual photoreceptors in vertebrates. Australia's underwater biodiversity is second to none with endemic species representing the earliest stages in vertebrate evolution, many of them relying heavily on vision for survival. Tracing the evolution of light detection and image formation will provide crucial information about the lifestyles of our vertebrate ancestors, the environmental selection pressures driving speciation and colour communication. Characterisation of optimal light environments and extra-ocular light detection will also help protect and manage endemic species in wild and captive environments. Read moreRead less
The entrainment of circadian rhythms in marsupial mammals: behavioural and sub-cellular investigation of non-rod, non-cone ocular photoreceptors. Our investigation will provide a contribution to understanding the role that photoreceptors play in the mechanisms that control circadian rhythms and will ultimately lead to a better understanding of the basic physiology of sleep and circadian cycles, their contribution to learning and memory and their impact on waking performance. Targeted drug develo ....The entrainment of circadian rhythms in marsupial mammals: behavioural and sub-cellular investigation of non-rod, non-cone ocular photoreceptors. Our investigation will provide a contribution to understanding the role that photoreceptors play in the mechanisms that control circadian rhythms and will ultimately lead to a better understanding of the basic physiology of sleep and circadian cycles, their contribution to learning and memory and their impact on waking performance. Targeted drug development and the design of lighting systems effective in regulating circadian rhythms will improve the quality of life and competitiveness of the many citizens who endure abnormal sleep/wakefulness schedules.Read moreRead less
