In the present study we assess the contribution of 32 species in the diet of both native Rhea americana and domestic (cattle) herbivore species and the abundance of these photosynthetic plant types in different environments in the lower section of the Del Plata Basin, Argentina, with a similar climate but with different hydrological regimes. The analysis of annual diets conducted in terms of photosynthetic types showed that the feedings patterns of wild as well as domestic herbivores varied both spatially and temporally.
