Between sites, Aitutaki had a higher density of branching corals in 2004, but there was no significant difference between the sites in 1980. Then density of coarse-branching corals has significantly decreased at both sites over time. Due to a higher proportional loss at Rarotonga, the density of coarse-branching corals (which was once similar at the sites), is lower in density at Rarotonga in 2004. Alternative Hypotheses for Fine-branching Coral: Hypothesis 1: Due to the increase in agriculture at Rarotonga since 1980, there has been an increase in organically enriched runoff. This has led to increased nutrients in the lagoon that are available to algae, organically enriched runoff....
