Note
In order to provide insight into the regulation of species densities of seagrass-associated macrobenthos, field experiments in the Indian River estuary, Florida were initiated in the seagrass Halodule wrightii to test effects of (1) excluding predators by caging, (2) enclosing predators inside cages, (3) adding dense populations of suspension feeders, (4) providing organic enrichment, (5) removing seagrass blades, and (6) erecting cages at different times. The 11 most abundant species were selected for statistical testing of responses to the experimental treatments.
