FIGURE 4 | A. Relationship between the hydrometric level and the consumption of all autochthonous items; B. The consumption of aquatic invertebrates; C. The consumption of detritus; D. And the consumption of fish for Trachelyopterus galeatus. Red graphs indicate a significant negative influence of the variable as a function of hydrometric level, while grayscale graphs indicate a non-significance.
