Sea urchin herbivory has been demostrated to be a controlling                   factor in limiting the distribution of kelp forest habitats.                    But as yet, its role in limiting the distribution of seagrass                   habitats in inadequately investigated.  In addition,                            bioturbation by infaunal invertebrates, i.e., ghost shrimp and                  sand dollars has also been suggested as limiting the local                      distribution of seagrass habitats, but the relative importance                  of bioturbation in controlling the size of seagrass meadows is                  also poorly understood.  Field experiments will be conducted                    to identify the roles of sea urchin herbivory, bioturbation                     of seagrasses by sand dollars, and the potential interaction                    between sand dollar bioturbation and sea urchin herbivory                       in limiting the distribution of seagrass habitats.  The                         results of this study should add to the existing body of                        knowledge and untested theories concerning the factors                          structuring nearshore ecosystems.
