Table 4. Loadings from an exploratory factor analysis using varimax rotation.

Four factors had eigenvalues > 1 and were therefore extracted. Blank cells had loadings <|0.1|.

	Factor 1	Factor 2	Factor 3	Factor 4
Simpson diversity index	0.366	0.114	-0.211	0.200
Fraction not diseased colonies				0.174
Percent hard coral cover	0.982		0.153
Percent not macroalgae cover				0.506
Rugosity	0.393	0.384		0.489
Total herbivore biomass		0.995
Temperature variation			-0.177
Average coral thermal tolerance	-0.343	-0.176	0.905	-0.167
Sum of squares loadings	1.393	1.188	0.931	0.600
Proportion variance explained	0.174	0.148	0.116	0.075
