In this study we analyzed grazing-induced vegetation changes by comparing 21 grazed- ungrazed pairs across steppes and grasslands of South America. Our results support the hypothesis that grazing impacts on vegetation structure increase with habitat productivity. We found that the magnitude of grazing-related differences in species composition, species richness and β diversity, all increased over a ten-fold productivity gradient.
