©2020 Biological and Chemical Oceanography Data Management Office.In this study, we tested the hypothesis that red urchins (Strongylocentrotus franciscanus) and lined chitons (Tonicella spp.) are redundant in the maintenance of available space, defined here as encrusting algae and bare rock. In a factorial field experiment replicated at three sites, we reduced the densities of urchins and chitons for nine months. The effects of grazers were interpreted in the context of natural temporal variation by monitoring the benthic community one year before, during, and after grazer removal.
