Starvation tolerance associated with prolonged sleep bouts upon starvation in a single natural population of Drosophila melanogaster.

ABSTRACT: Large genetic variations in starvation tolerance in animals indicate that there are multiple strategies to cope with low-nutrient conditions. Fruit flies (Drosophila melanogaster) typically respond to starvation by suppressing sleep and enhancing locomotor activity presumably to search for food. However, we hypothesized that in a natural population, there are costs and benefits to sleep suppression under low-nutrient conditions and that conserving energy through sleep could be a better strategy depending on food availability. In this study, we quantified the variation in sleep-related traits in 21 wild-derived inbred lines from Katsunuma, Japan, under fed and starved conditions and analysed the relationship between those traits and starvation tolerance. Although most of the lines responded
