Fig. 2 in Feeding strategy of the introduced Astronotus crassipinnis (Cichlidae) in upper Paraná river floodplain
Fig. 2. Ordination by principal coordinate analysis (PCoA) of the food items for the size classes of Astronotus crassipinnis (Heckel, 1840) along the upper Paraná River floodplain. Axis 1 separated the diet of Class I (spheres on the right) from the other two classes (square and diamond in the left, with little variability) (Chiro, Chironomidae larvae; Ostra, Ostracoda; Ephe, Ephemeroptera).

FIGURE 3 in Monogenea on exotic Indian freshwater fish. 5. First report of pathogenic Gussevia asota (Platyhelminths) from Oscar Astronotus ocellatus (Agassiz 1831) (Perciformes: Cichlidae)
FIGURE 3. Phylogenetic tree inferred from ML method based on partial 28S rDNA gene sequences of Gussevia asota Kritsky et al., 1989. Numbers preceding the taxa are GenBank accession numbers for their 28s rRNA gene sequences. Bootstrap values (1000 replicates) are shown above nodes. Quadriacanthus bagrae and Thaparocleidus siluri were used as the outgroups. The taxon denoted by a black dot corresponds to the sequence generated in this study.
