节肢动物捕食者之间共生关系的健身效果：蜘蛛三方共生中的协同作用

不同种类的蜘蛛共同生活在同一张蜘蛛网上，这为利用野外实验研究节肢动物捕食者之间种间相互作用的性质提供了大量机会：蜘蛛网复合体易于发现和监测；寄主蜘蛛的流动性较低，可以通过野外实验揭示适应性效应；蜘蛛的行为易于观察。这种多物种共生中的伙伴组合可能在地理上有所不同，因为在不同的时空尺度上，Leucauge 和 Argyrodes 客体的地理范围往往超过它们共同宿主的地理范围。在这里，我们利用野外实验揭示了由 Cyrtophora 宿主及其两种同居蜘蛛客体（织网的 Leucauge 和寄生的 Argyrodes）组成的多物种共生对参与蜘蛛的觅食影响。值得注意的是，我们在纬度范围广泛的不同地理位置重复了实地实验，每个实验都涉及不同物种的参与伙伴组合（图 1），从而为我们的经验推论提供了前所未有的地理通用性。我们提出了以下问题：(1) 三种参与者是否对宿主的捕食效率有各自的影响；(2) Cyrtophora 宿主和 Argyrodes 客体的捕食机制（反映了猎物的大小范围）是否受到 Leucauge 造网客体存在的调节；(3) 当单独存在或与不同的客体物种组合共存时，共生对宿主的潜在适应性后果（通过体重变化估算）是什么？通过操纵该系统中节肢动物捕食者的物种组成，我们的研究揭示了多物种共生中不同共生体的叠加效应和协同效应。

期刊介绍： Functional Ecology publishes high-impact papers that enable a mechanistic understanding of ecological pattern and process from the organismic to the ecosystem scale. Because of the multifaceted nature of this challenge, papers can be based on a wide range of approaches. Thus, manuscripts may vary from physiological, genetics, life-history, and behavioural perspectives for organismal studies to community and biogeochemical studies when the goal is to understand ecosystem and larger scale ecological phenomena. We believe that the diverse nature of our journal is a strength, not a weakness, and we are open-minded about the variety of data, research approaches and types of studies that we publish. Certain key areas will continue to be emphasized: studies that integrate genomics with ecology, studies that examine how key aspects of physiology (e.g., stress) impact the ecology of animals and plants, or vice versa, and how evolution shapes interactions among function and ecological traits. Ecology has increasingly moved towards the realization that organismal traits and activities are vital for understanding community dynamics and ecosystem processes, particularly in response to the rapid global changes occurring in earth’s environment, and Functional Ecology aims to publish such integrative papers.
