Effect of Heliocidaris erythrogramma on benthic macroalgae and drift retention
Two experiments were performed. The first was designed to test for effects of Heliocidaris at different densities, using fenced plots in which the densities of Heliocidaris were controlled. The second (which was repeated twice) was designed to test for effects of natural densities of sea urchins on benthos, using unfenced plots from which all sea urchins were removed.
