Fig. 4 in Diet and body shape among populations of Bryconamericus iheringii (Otophysi: Characidae) across the Campos Sulinos ecosystem

Fig. 4. Partial least squares canonical analysis depicting the covariation between: a. dietary (blue) and environmental (brown) variables; b. morphological (orange) and environmental (brown) variables; c. dietary (blue) and morphological variables (orange). Variables near the edge of the circle are better represented by the model. Variables near one another are positively correlated, whereas variables opposite one another are negatively correlated. Uncorrelated variables are orthogonal.
