As a result of co-evolution between plants and herbivores, related plants often interact with similar herbivore communities. Variation in plant-herbivore interactions is determined by variation in underlying functional traits and by ecological and stochastic processes. Hence, typically, only a subset of possible interactions is realised on individual plants. We show that insect herbivore communities assembling on individual plants are structured by plant phylogeny among 12 species in two phylogenetic lineages of Brassicaceae. This community sorting to plant phylogeny was retained when splitting the community according to herbivore feeding guilds. Relative abundance of herbivores as well as the size of the community structured community dissimilarity among plant species. Importantly, the amount of intraspecific variation in realised plant-herbivore interactions is also phylogenetically structured. We argue that variability in realised interactions that are not directly structured by plant traits is ecologically relevant and must be considered in the evolution of plant defences.
由于植物和草食动物之间的共同进化，相关的植物经常与类似的草食动物群落相互作用。植物与草食动物相互作用的变化取决于潜在功能特征的变化以及生态和随机过程。因此，通常只有可能的相互作用的子集在单个植物上实现。我们表明，在两个十字花科的系统发育谱系中的 12 种植物上，组装在单个植物上的昆虫草食动物群落是由植物系统发育决定的。当根据草食动物的摄食习性将群落分开时，这种对植物系统发育的群落分类仍然存在。食草动物的相对丰度以及群落的大小决定了植物物种之间的群落差异。重要的是，实现的植物-草食动物相互作用的种内变异量也是系统发育结构的。我们认为，不是直接由植物特征结构决定的实现相互作用的可变性在生态学上是相关的，并且在植物防御的进化中必须考虑到这一点。
