Most Australian marsupials are nocturnal and consequently it might be expected that the circadian system of this group may be similar to the circadian system of nocturnal rodents. Ten male kowaris (Dasyuroides byrnei) were allowed to free-run in constant darkness and were subsequently administered 1-hour light pulses (1000 lux) at known circadian times in their cycles at intervals of greater than 2 weeks. Changes in the phase of the kowari's circadian rhythm of wheel-running were measured when… CONTINUE READING
