Calls and constraints: do male frogs signal direct benefits? There is international concern over recent declines and disappearances of many species of amphibians. Australia is a hotspot for declines, but causes of declines remain enigmatic. Approximately one quarter of Australia's 230 amphibian species breed in terrestrial situations, but processes such as salinity, wetland and urban developments and climate change are altering the hydrology of our landscape, and preventing the flood events nece ....Calls and constraints: do male frogs signal direct benefits? There is international concern over recent declines and disappearances of many species of amphibians. Australia is a hotspot for declines, but causes of declines remain enigmatic. Approximately one quarter of Australia's 230 amphibian species breed in terrestrial situations, but processes such as salinity, wetland and urban developments and climate change are altering the hydrology of our landscape, and preventing the flood events necessary for the completion of the lifecycle of many species. This research has important conservation implications because it examines the effects of variable moisture regimes on the physiology and reproductive behaviours of terrestrial breeding frogs.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
