Webexample, among herbaceous grassland species, taller species often flower later than shorter ones (Dahlgren, von Zeipel & Ehrle´n 2007; Du & Qi 2010). However, it is still ambiguous whether flowering phenology largely depends on height growth pattern in grassland species, because two critical ques-tions have not been fully addressed. WebGrasslands and their grazers provide some of the most compelling examples for studying the relationship between diversity, productivity, and disturbance. In this study, we analyzed the impact of grazing-induced changes in species composition and community structure upon the productivity of a grassland in the Campos region, Uruguay.
