FIGURE 1 | Map depicting the Volta Grande do Xingu (Xingu River, Brazil), with emphasis on the reduced flow section created by the construction of the Belo Monte Dam (including the Pimental Dam). The orange circles represent the sampling sites where Pimelodus blochii specimens were collected, and the arrows indicate the direction of water flow. The orange star and triangle represent the Pimental Dam and the Belo Monte Dam, respectively.

Fig. 2 in Impacts of ontogenetic dietary shifts on the food-transmitted intestinal parasite communities of two lake salmonids

Fig. 2. Correlation between the mean number of parasite taxa and mean length among the different size classes of Arctic charr and brown trout with a 95% confidence interval.

Fig. 1 in Impacts of ontogenetic dietary shifts on the food-transmitted intestinal parasite communities of two lake salmonids

Fig. 1. Frequency of occurrence of prey categories in the diet of a) Arctic charr and b) brown trout throughout their ontogenesis. Prey categories not related to intestinal parasite transmission are excluded.

Fig. 4 in Impacts of ontogenetic dietary shifts on the food-transmitted intestinal parasite communities of two lake salmonids

Fig. 4. Nonmetric multidimensional scaling (NMDS) plot on Bray-Curtis distances of a) Arctic charr and b) brown trout showing dissimilarity in parasite community composition between different size classes including 95% confidence intervals ellipses. NMDS converged on a three-dimensional solution with an acceptable stress level.

Fig. 7 in Impacts of ontogenetic dietary shifts on the food-transmitted intestinal parasite communities of two lake salmonids

Fig. 7. Canonical correspondence analysis (CCA) performed on parasite abundances as a function of presence-absence of prey types and fish length in a) Arctic charr and b) brown trout (Cre. = Crepidostomum spp., Cya. = Cyatocephalus truncatus, Eub.s. = Eubothrium salvelini, Eub.c. = Eubothrium crassum, Pro. = Proteocephalus sp., Dib. = Dibothriocephalus spp.).

Fig. 5. Differences in parasite community composition between Arctic charr and brown trout using nonmetric multidimensional scaling (NMDS) plot on Bray-Curtis distances, including 95% confidence interval ellipses. NMDS converged on a three-dimensional solution with an acceptable stress level.
