In various animal taxa, prior experience of contests influences the consequences of subsequent contests. A well‐known example is the winner and loser effects, in which winners have a higher winning probability, whereas losers become more likely to lose in the subsequent contests. Previous studies have suggested that the intensity of past contests also affects the future winning probability in two...
Females of many animal species mate several times with different males (polyandry), whereas females of some species mate with a single male (monandry) only once. Little is known about the mechanisms by which these different mating systems evolve. Females of Drosophila prolongata mate serially, unlike Drosophila melanogaster females that refuse to remate for several days after their first mating (remating...
Tolerance to extreme temperatures is one of the most important components of adaptation to environments in insects. However, the genetic mechanisms of tolerance to long-term heat stress are mostly unknown. In this study, we investigated the genetic variation of susceptibility to long-term heat stress among the isofemale strains of Drosophila prolongata Singh & Gupta. High rates of pupal lethality...
