理论和实验证据表明，在一定条件下，雌性会模仿其他雌性的择偶行为。在所有的择偶复制实验与鱼的日期，女性被允许复制的选择模型女性后，立即焦点女性观察到一个模型女性与男性互动。不知道女性是否会在更长的时间间隔后继续复制女性模型的选择。我们调查是否sailfin molly女性也复制其他女性的选择时，他们被阻止复制后立即观察一个模型女性旁边的一个以前不喜欢的男性。我们进行了三个复制实验中，女性可以复制模型女性的选择后立即，1小时后或1天后，观察模型女性旁边的先前非首选的男性。在对照实验中，我们测试了女性是否选择一致时，他们没有机会复制，以及女性是否表现出浅滩行为在这些条件下。女性复制模型女性的选择后立即，1小时后，甚至1天后，观察模型女性与以前的非首选男性的互动。女性之间的选择一致的男性时，他们没有机会复制，和女性没有浅滩在这些条件下。我们的结论是，女性记得个别男性与模型女性互动，即使1天后。版权所有2003由爱思唯尔科学有限公司代表动物行为研究协会出版。
Abstract Theoretical and experimental evidence indicates that females copy the mate choice of other females under certain conditions. In all mate choice copying experiments with fish to date, females were allowed to copy the choice of a model female immediately after the focal female had observed a model female interacting with a male. It is not known whether females continue to copy the choice of the model female after a longer interval. We investigated whether sailfin molly females also copy the choice of other females when they are prevented from copying immediately after observing a model female next to a previously nonpreferred male. We performed three copying experiments in which females could copy the choice of the model female immediately after, 1 h after or 1 day after observing the model female next to the previously nonpreferred male. In control experiments, we tested whether females chose consistently when they had no opportunity to copy, and whether females showed shoaling behaviour under these conditions. Females copied the choice of the model female immediately after, 1 h after and even 1 day after the observation of the model female interacting with the previously nonpreferred male. Females chose consistently between males when they had no opportunity to copy, and females did not shoal under these conditions. We conclude that females remember individual males with whom a model female had interacted, even after 1 day.
