| In this study, we examined some aspects regarding the effect of willow trees (Salix fragilis L.) invasion of grassland riparian environments in the Argentinean Pampas on the runof reduction, sedimentation and glyphosate retention in the riparian vegetation strip (RVS). To assess the influence of willows on the filtering mechanisms, we performed runof simulation experiments in plots of 1.5 x 2.5 m, in coastal environments characterized by the presence of willows or the lack of trees. Despite the short length of the experimental plots, the retention of glyphosate in the controls, with no trees, was higher and reached almost 74%. Nevertheless, sediment retention did not differ significantly between the tree areas and the grassy controls. The runoff reduction... |

| ABSTRACT Algal turfs are currently the most abundant benthic component on most coral reefs. Their wide distribution, functional role and positive response to factors that stress corals confirm their importance in the functioning of reef ecosystem. It has been shown that species composition, structural development and sediment retention influence their capacity to kill and displace adjacent live coral tissue. In this study in two reefs of the Tayrona National Natural Park (Colombian Caribbean), the variation in structure of turfs growing on and in direct interaction with massive live corals was determined, and its structural complexity was related with its sediment retention capacity. For that, the taxonomical composition was determined, and canopy height,... |
