Colour constancy in diurnal and nocturnal hawkmoths.
Diurnal and nocturnal hawkmoths have been shown to use colour vision for flower discrimination. Here, we present evidence that the nocturnal hawkmoth Deilephila elpenor and the diurnal hawkmoth Macroglossum stellatarum also have colour constancy. Colour constancy was shown in D. elpenor in two multiple-choice experiments with five different bluish colour patches under white and blue illuminatio...

متن کاملWorking for Food Shifts Nocturnal Mouse Activity into the Day
Nocturnal rodents show diurnal food anticipatory activity when food access is restricted to a few hours in daytime. Timed food access also results in reduced food intake, but the role of food intake in circadian organization per se has not been described. By simulating natural food shortage in mice that work for food we show that reduced food intake alone shifts the activity phase from the nigh...
متن کاملParoxysmal activity and seizures associated with sleep breathing disorder in children: A possible overlap between diurnal and nocturnal symptoms
PURPOSE Sleep breathing disorders (SBD) can trigger paroxysmal events. We recently found a higher percentage of paroxysmal activity (PA) in a sample of Italian children with obstructive sleep apnea syndrome (OSAS) and no history of epilepsy. The signs of nocturnal seizures can overlap with sleep respiratory events. The aim of this study was to confirm the high frequency of PA or interictal epil...
متن کاملOcellar optics in nocturnal and diurnal bees and wasps.
Nocturnal bees, wasps and ants have considerably larger ocelli than their diurnal relatives, suggesting an active role in vision at night. In a first step to understanding what this role might be, the morphology and physiological optics of ocelli were investigated in three tropical rainforest species - the nocturnal sweat bee Megalopta genalis, the nocturnal paper wasp Apoica pallens and the di...
