Scatter plot of the principal component analysis (PCA) of factors that influence the species richness and diversity of the parasite infracommunities of Caranx sexfasciatus, from Acapulco Bay. 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), K_n = condition factor, Diet = host diet variety, EndoR = number of endoparasite species, EctoR = number of ectoparasite species, EndoT = total number of endoparasites per host, EctoT = total number of ectoparasites 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.
