本文描述了“反向敲击“作为一种特征性的交配行为在Pagurusnigrofascia。这种行为包括一只寄居蟹把另一只螃蟹的壳拉向自己，导致壳互相碰撞。这是第一个证据表明，男性执行反向说唱作为一种交配行为在一个Pagurus物种。通过两个实验对反振打进行了详细的描述，并讨论了反振打的作用。在实验A中，我们艾德雄性在什么时候（交配季节或非交配季节）以及对谁（雄性或雌性）表现出这种行为。一只没有在野外守卫的焦点雄性螃蟹与另一只螃蟹放在一起，观察它们的相互作用，特别是反向敲击。在交配季节，雄性主要表现为与接近交配的雌性发生反向交配，尤其是当雄性守卫雌性时。在实验B中，我们检查了女性对男性反向敲击的反应，并测试了邻居的存在对行为发生的影响。大多数雌性动物在听到雄性动物的反向敲击后会减少挣扎和/或缩入壳中。附近螃蟹的出现并没有产生明显的反作用。我们的研究结果表明，反向敲击是黑筋膜P. nigrofascia的一种交配行为，反向敲击可能贝内男性开始和/或继续进行prepulatory守卫，因为它可以帮助抑制挣扎的女性。这种行为在其他同域寄居的寄居蟹中没有观察到，似乎是黑带寄居蟹的一种特征性交配行为。
: This paper describes “ inverse rapping ” as a characteristic mating behavior in Pagurus nigrofascia . The behavior involves one hermit crab pulling another crab ʼ s shell towards itself causing the shells to hit against each other. This is the first evidence that males perform inverse rapping as a mating behavior in a Pagurus species. Two experi-ments were conducted to describe the inverse rapping in detail and to discuss its function. In Experiment A, we clarified when (mating season or non-mating season) and to whom (males or females) males displayed this behavior. A focal male that had not been guarding in the field was placed together with another crab and their interaction was observed, especially inverse rapping. Males showed inverse rapping mainly with a female that was close to copulation in the mating season, especially when the male guarded the female. In Experiment B, we examined the female ʼ s response to male inverse rapping and tested the effect of the presence of a neighboring conspecific on the occurrence of the behavior. Most females reduced struggling and/or withdrew into their shells in response to male inverse rapping. The presence of neighboring crabs did not affect inverse rapping. Our findings suggest that inverse rapping is a mating behavior in P. nigrofascia , and that inverse rapping may benefit males in the initiation and/or continuation of precopulatory guarding because it can help to restrain struggling females. This behavior has not been observed in other sympatric Pagurus species and appears to be a characteristic mating behavior of P. nigrofascia .
