| The indirect impact of flower herbivory on plant reproduction depends on the pollination environment, particularly on the presence or absence of pollinator species with the ability to discriminate damaged from undamaged flowers. The change in pollinator assemblages, due to habitat modification, may modify the impact of flower herbivory on plant reproductive success. In this work, we evaluate the effect of flower herbivory on the seed production of Viola portalesia (Gay) in two contrasting environments, a native and low-disturbed habitat and an extensively transformed habitat characterized by Pinus radiata plantations. Even though the two habitats differed substantially in the composition of pollinator assemblages and visitation rate, the flower damage... |

| Egeria densa Planchón is considered an invasive species in continental aquatic systems in Chile. Its original geographical distribution was limited to the subtropical regions of Brazil, Argentina and Uruguay. Its fast growth and dense canopy-forming habit are associated with the clear water state of shallow water continental ecosystems. As a dominant species in many of the systems in which it occurs, E. densa behaves as an ecosystem engineer by preventing the re-suspension of sediments and controlling the growth of phytoplankton by removing nutrients from the water column. At the same time, this invasive species produces unwanted effects such as: (1) clogging waterways and hydroelectric turbines, (2) out-competing native vegetation, and (3) negatively... |
