摘要1.棉白杨（Populus spp.） 在这些河岸森林中，海狸（Castor canadensis）是一种主要的生态系统工程师，通常会浏览棉白杨，导致植物结构的明显变化。在这里，海狸食草动物间接影响分布的梯形叶刺叶蜂通过建筑的变化在三角叶杨的假设进行了检查。
Abstract 1. Cottonwood (Populus spp.) are the dominant tree type in riparian forests of the western U.S.A. In these riparian forests, the beaver (Castor canadensis) is a major ecosystem engineer that commonly browses cottonwood, resulting in distinct changes to plant architecture. Here the hypothesis that beaver herbivory indirectly affects the distribution of a keystone leaf‐galling sawfly through architectural changes in cottonwood was examined.
