摘要：

We used reciprocal exclusions to test for indirect interactions between pocket gophers (Thomomys talpoides) and aboveground insects. Sucking insects occurred at higher densities on plants that were protected from grazing by gophers (P < 0.05), whereas chewing insects damaged plants that were browsed by gophers more than plants that were protected from gopher herbivory (P < 0.05). Pocket gophers foraged more in areas treated with insecticide (P < 0.05). These results indicate that aboveground insects and the northern pocket gopher interacted through their shared plant hosts.
