Relationships between photosynthetic plant types in the diet of herbivore mammals and in the environment in the lower Paraná river Basin, Argentina
In the present study we assess the contribution of C3, C 4 and intermediate C3-C4 plant species to the diet of both native (Hydrochoerus hydrochaeris, Rhea americana and Logostomus maximus) and introduced (cattle) herbivore species and the abundance of these photosynthetic plant types in different e...
