AbstractDefensive mimicry systems are typically categorized into two types: Batesian, involving a defenseless mimic and a defended model, or Mullerian, involving two or more defended co-models. More recent theoretical treatments of mimicry predict that the nature of a single mimicry system may vary over space and time. In this proposal, the work incorporates both the phenology and the geography of three butterfly species to assess the dynamics of two well-known mimicry systems: the viceroy/monarch system and the viceroy/queen. While these systems were originally classified as Batesian mimicry, accumulating evidence suggests that the viceroy is often unpalatable to avian predators, while the models, the monarch and queen, can often be palatable. Thus, the viceroy mimicry complex may span the continuum with roles of model and mimic changing through space and time. This work will document the chemistry responsible for unpalatability, spatial and temporal variation in chemical defense of the three butterfly species, and variation in palatability to vertebrate and invertebrate predators.

摘要防御性模仿系统通常分为两种类型：Baidian，涉及一个无防御的模仿者和一个有防御的模型，或Mullerian，涉及两个或多个有防御的协同模型。 最近对拟态的理论研究预测，单一拟态系统的性质可能随时间和空间而变化。 在这项提案中，这项工作结合了三种蝴蝶的物候学和地理学，以评估两个著名的拟态系统的动态：总督/君主系统和总督/女王。虽然这些系统最初被归类为巴塞罗拟态，但越来越多的证据表明，总督通常不受鸟类捕食者的欢迎，而模型，君主和女王，往往是美味的。因此，总督拟态复合体可能跨越了连续体，模型和模仿者的角色在空间和时间上不断变化。这项工作将记录负责unpalatability，空间和时间的变化，在化学防御的三种蝴蝶的化学，和可口的脊椎动物和无脊椎动物捕食者的变化。
