Relative herbivory tolerance and competitive ability in two dominant

We evaluated herbivory tolerance and competitive ability within two dominant: subordinate pairs of C 4, perennial grasses at each of two sites to determine the contribution of these processes to herbivore-induced species replacement. Herbivory tolerance was assessed by cumulative regrowth from defol ...
