生物体已经进化出了形态和行为特征，这些特征降低了它们对捕食的敏感性。然而，很少有研究考虑形态结构如何工作，以提供必要的信息输入有效的行为反应捕食风险。在这项研究中，我们证明，毛Orgyia leucostigma（毒蛾科）毛虫不仅作为物理屏障，阻止捕食者，但也采取行动，提供感官输入触发行为，降低捕食风险。特别是，毛毛虫的毛被触摸时的反应方式是捕食者特有的。确定响应的相互作用的机械参数进行了相关性鉴定和确认操作。毛毛虫主要下降，以响应高的头发弯曲速度和主要走开，以响应低的头发弯曲速度。这些刺激特异性反应似乎是适应性的，因为它们导致生存率增加。我们的研究结果表明，形态和行为之间的功能联系。只有在捕食者攻击开始后才能有效地作出反应，这应该会减少与反捕食者行为相关的成本。版权所有2011，牛津大学出版社。
Organisms have evolved morphological and behavioral traits that reduce their susceptibility to predation. However, few studies have considered how morphological structures work to provide informational inputs necessary for effective behavioral responses to predation risk. In this study, we demonstrate that the hairs of Orgyia leucostigma (Lymantriidae) caterpillars not only function as physical barriers that deter predators but also act to provide sensory inputs triggering behavior that reduces predation risk. In particular, the way in which caterpillars respond when their hairs are touched is predator specific. Mechanical parameters of the interaction determining the response were identified correlatively and confirmed manipulatively. Caterpillars predominantly dropped in response to high hair bending velocities and predominantly walked away in response to low hair bending velocities. These stimulus-specific responses appear to be adaptive as they led to increased survival. Our results demonstrate a functional link between morphology and behavior. The ability to respond effectively only after the initiation of a predator attack should reduce the costs associated with antipredator behaviors. Copyright 2011, Oxford University Press.
