The effect of mating on starvation resistance in natural populations of Drosophila melanogaster
In nature, behavioural and physiological processes involved in mating may entail different costs and benefits for males and females. However, it has been hypothesized that sexual interactions may have additional costs for Drosophila females like decrease in receptivity to remating and shortening of...
