Conteúdo: | Species forming tussocks are common in complex pastoral systems like the grasslands of the Pampas biome. A detailed knowledge of tussock structure is the key to understand the relationships between plants and animals. The abundance and defoliation patterns of caespitose species can be influenced by management that uses animals as the principal agents of structural changes driven by selective grazing (Laca et al., 2001). Thus, factors that determine selection or avoidance of tussocks by cattle can determine the structure and dynamics of tussocks. We evaluated tussock botanical composition and physical structure as factors to explain patterns of defoliation of the upper stratum in natural pastures with and without fertilization and overseeding.
