Phenotypic changes in plants during domestication may disrupt plant–herbivore interactions. Because wild and cultivated plants have different habitats and some anti-herbivore defences exhibit some plasticity, their defences may be also influenced by the environment. Our goal was to assess the effects of domestication and the environment on herbivory and some anti-herbivore defences in chaya (Cnidoscolus aconitifolius) in its centre of domestication. Herbivores, herbivory, and direct and indirect anti-herbivore defences were assessed in wild and cultivated plants. The same variables were measured in the field and in a common garden to assess environmental effects. Our results show that domestication increased herbivory and herbivore abundance, but reduced direct and some indirect defences (ants). The environment also affected the herbivore guild (herbivore abundance and richness) and some direct and indirect defences (trichome number and ants). There was also an interaction effect of domestication and the environment on the number of trichomes. We conclude that domestication and the environment influence herbivory and anti-herbivore defences in an additive and interactive manner in chaya.

野生和栽培的乌头蚴的食草动物和反食草动物防御：解开驯化和环境影响。


驯化过程中植物的表型变化可能会破坏植物与草食动物的相互作用。由于野生和栽培植物具有不同的栖息地，并且一些反草食动物的防御表现出一定的可塑性，因此它们的防御也可能受到环境的影响。我们的目标是评估驯化和环境对驯化中心查亚（ Cnidoscolus aconitifolius ）食草动物和一些反草食动物防御的影响。在野生和栽培植物中评估了食草动物、食草动物以及直接和间接的反食草动物防御。在田间和公共花园中测量了相同的变量，以评估环境影响。我们的结果表明，驯化增加了食草动物和食草动物的丰度，但减少了直接和一些间接防御（蚂蚁）。环境还影响食草动物行会（食草动物数量和丰富度）以及一些直接和间接的防御（毛状体数量和蚂蚁）。驯化和环境对毛状体数量也存在相互作用。我们得出的结论是，驯化和环境以累加和交互的方式影响查亚的食草动物和反食草动物防御。
