From the results of a comparative study using quantitative standardized assays of the scale and precision of responses of root and shoot systems to resource patchiness, Campbell et al. (1991; Oecologia 87: 532-538) proposed a mechanism of species coexistence in herbaceous communities involving a dynamic equilibrium between, respectively, the coarse- and fine-scale foraging of dominant and subordinate species. The purpose of this paper is to reject a recent assertion that with respect to root systems the scale-precision hypothesis has been falsified.
