Augspurger, Carol K. Beckstead, Julie 2015-09-28T15:22:36Z 2015-09-28T15:22:36Z 10000-01-01 2001 2001 Linking theories of invasion biology with that of associational herbivory, I found that (1) cheatgrass was a highly utilized food source for generalist grasshoppers, (2) among native plant species, the amount of herbivory corresponded with their total percent nitrogen and other plant traits, and (3) a native grass, Elymus elymoides, experienced higher herbivory in high- than in low-density cheatgrass patches, supporting the attractant-source hypothesis that predicts associational susceptibility. Through indirect effects, invading species may generate important shifts in herbivory on native species. Made available in DSpace on 2015-09-28T15:22:36Z (GMT).
