Effects of a past contest on the future winning probability in a hyper-aggressive fruit fly

【Abstract】
In many animals, the “winner/loser effect” is known to make individuals more likely to win/lose the next fight based on their past victories or defeats. However, in Drosophila prolongata, we found that past winners are just as likely to lose as losers. Moreover, by the experiments that manipulated the intensity of fights by adjusting the size of opposing individuals, we found that the intensity of fights may be the cause of why winners are more likely to lose. This study demonstrates that the role of experience in animal fights is diverse and cannot be solely explained by the winner/loser effect.
