Figure 5 in Temporal dynamics of parasite populations and communities of blue sea catfish Ariopsis guatemalensis (Günther, 1864), in a eutrophic coastal lagoon from Mexican Pacific

Figure 5. Scatter plot of principal component analysis (PCA) of factors that influence the species richness and diversity of the parasite infracommunities of Ariopsis guatemalensis, from Tres Palos lagoon. 'Predictor variables': Season = climatic season, Month = sampling month, GRI = gastric repletion index, GSI = gonadosomatic index, CF = condition factor, Size = host body size (total length), Sex = sex of the host. Infracommunity parameters: Richness = number of parasite species per host, Diversity = Brillouin diversity index values, Load = total number of parasites per infracommunity, Evenness = species evenness, RHsp = number of heteroxenous parasite species, THsp = total number of heteroxenous parasites, TMsp = total number of monoxenous parasites. Ellipses represent sampling months.
