Centroid: latitude: -17.476944, longitude: -149.839167
Temporal Extent: -

Methodology:

Each coral in each plot was visually examined from all sides and the percentage tissue mortality was estimated and assigned in 10% classes (0, 10 and 20% and so on, up to 100%).

Sampling and analytical procedures:

We used permutation-based, linear mixed-effects (LME) models in the R package predictmeans to compare differences in the percentage mass change and tissue mortality of conspecific corals in monocultures versus polyculture, as well as the combined percentage mass change of all species in polycultures with that of all species in monocultures. In each analysis, plot type (monoculture or polyculture) was treated as a fixed factor, and individual replicate plots were treated as a random effect nested within plot type.
