Altitudinal variation in the circadian rhythm of oviposition in Drosophila ananassae.

abstract：:To compare the behavioral effects of sleep-loss sleepiness (performance impairment due to sleep loss) and sleep inertia (period of impaired performance that follows awakening), mean response latencies and number of lapses from a visual simple reaction-time task were analyzed. Three experimental conditions were designe...
