FIGURE 3 in Genetic differentiation through dispersal and isolation in two freshwater fish species from coastal basins of Northeastern Brazil
FIGURE 3 | Distribution and haplotype structure of Prochilodus lacustris. A. Paleodrainage reconstruction of coastal basins from northeastern Brazil and geographic distribution of groups defined by SAMOVA. B. Estimate of the probable groups of populations produced by the BAPS. C. Haplotypes networks of mtDNA control region.

Fig. 2 in Chromosome evolution in fishes: a new challenging proposal from Neotropical species
Fig. 2. Scatter-plot of (a, c) diploid number (2n), and (b, d) pg of DNA per haploid nucleus (C-Value), against the phylogenetic position of Actinopterygii families presented by Nelson (2006). Data include all available species (a, b) or exclude possible polyploidy species (c, d). Ellipses with 95% confidence are used as a correlation indicator.

Fig. 6 in The effect of structural enrichment in hatchery tanks on the morphology of two neotropical fish species
Fig. 6. Most important ecomorphological attributes for Brycon orbignyanus in the morphological differentiation among treatments, according to the ANOVA and the DCA, concomitantly. Treatments with a different letter above their ranges differed significantly.
Fig. 3 in The effect of structural enrichment in hatchery tanks on the morphology of two neotropical fish species
Fig. 3. Condition factors (CFs) for Prochilodus lineatus and Brycon orbignyanus. The ANOVA was significant for both species (p <0.0001), demonstrating significant differences among the treatments. The results of the Tukey tests specifying which CFs were different from each other is demonstrated by the letters A, B, and C. Different letters indicate significant differences among the treatments.
Fig. 1 in Predictive factors of species composition of follower fishes in nuclear-follower feeding associations: a snapshot study
Fig. 1. Selected examples of nuclear-follower fish associations recorded in a stream in Southwestern Brazil: Leporellus vittatus begins to approach the bottom, while followed by a small group of Jupiaba acanthogaster (A); Leporinus macrocephalus disturbs the bottom, while Crenicichla vittata approaches to feed on fleeing or uncovered prey (B); L. macrocephalus stirs a little cloud, while a small group of Odontostilbe pequira and J. acanthogaster approaches (C); the same nuclear species stirs a large cloud, which congregates large numbers of O. pequira (D); Prochilodus lineatus begins to probe on the bottom, readily attracting a small group of O. pequira and J. acanthogaster (E); the same nuclear species stirs a large sediment cloud, which attracts large numbers of O. pequira (F).

Fig. 7. The log of the distance from the centroid plus 1 [log (DC+1)] for Prochilodus lineatus and Brycon orbignyanus. The ANOVA was significant for both species (p <0.0001), demonstrating significant differences among the treatments. The results of the Tukey tests, specifying which DCs were different from each other, are demonstrated by the letters A, B, and C. Different letters indicate significant differences among the treatments.
