Conteúdo: | This study examined the effect of crowding on the size of the floating and submerged leaves of Salvinia auriculata. In addition, we examined investment in reproductive structures( sporocarps) in response to the size of ramets. Ramets of S. auriculata growing on the surface of lagoons in the Southern Pantanal were sampled from populations of different densities. Ramets under densely crowded conditions were significantly larger than ramets under uncrowded conditions. There was a tendency for the number of sporocarps to increase with the size of submerged leaves, but not with lenght or specific area of floating leaves. The results indicate that S. auriculata exbibit density-dependent morphological plasticity, and may be a reflection of an envolved strategy that increases competetive ability of the ramets. It further suggests that increase in production of sporocarps may not be a simple response to the size of ramets.
