Summary of the principal component analysis (PCA) on biotic and abiotic factors that influence the diversity and species richness of the infracommunities of Caranx sexfasciatus. The three principal component axes are indicated by PC1, PC2 and PC3, respectively. Variables that contribute to the total explained variance in each PC are in bold. Eigenvalues, percentage of variance, and accumulative variance are shown at the end of the table. Communality = total influence of the variable with respect to all other associated variables. Uniqueness = percentage of variability that is not predicted by the variable in the model.
|Variables||PC1||PC2||PC3||R 2||% not predicted|
|% total variance||24.9||19.8||17.18|
Predictor variables: Year = sampling year, Season = climatic season (dry/rainy), Temp = surface temperature values, Enso = Multivariate El Niño index, Size = host body size (total length), Kn = condition factor, Diet = host diet variety, EndoR = number of endoparasite species, EctoR = number of ectoparasite species, EndoT = total number of endoparasite per host, EctoT = total number of ectoparasite per host. Infracommunity parameters: Richness = number of parasite species per infracommunity, Diversity = Brillouin diversity index values, Load = total number of parasites per infracommunity, Evenness = species evenness.
