It has been argued that intraspecific mate-choice copying can be adaptive under certain conditions. Dugatkin's (1992, Am. Nat.139, 1384-1389) work with guppies, Poecilia reticulataremains the most influential experimental demonstration of this phenomenon. We replicated Dugatkin's work using several choice criteria to ensure that our results were not dependent upon any single method of judging mate choice. We also tested our findings against two null hypotheses of differing stringency. Irrespective of the choice criteria or null hypothesis used, we did not observe any relationship between female mate choice and copying. We conclude that further experimental evidence of female mate-choice copying is required before the existence of this behaviour can be affirmed.1997The Association for the Study of Animal Behaviour
有人认为，种内择偶模仿在某些情况下可能具有适应性。杜加金（1992年，《美国博物学家》139卷，第1384 - 1389页）对孔雀鱼（Poecilia reticulata）的研究，仍然是这一现象最具影响力的实验证明。我们使用多种选择标准重复了杜加金的研究，以确保我们的结果不依赖于任何单一的判断择偶的方法。我们还根据两个不同严格程度的零假设检验了我们的发现。无论使用何种选择标准或零假设，我们都没有观察到雌性择偶与模仿之间存在任何关系。我们得出结论，在确认这种行为存在之前，需要进一步的实验证据来证明雌性择偶模仿行为的存在。1997年动物行为研究协会
