Ecosystem impacts of the invasive bivalve Limnoperna fortunei (golden mussel) in South America

We summarize current knowledge on the effects of the invasive Asian bivalve Limnoperna fortunei (introduced in South America around 1990) on local biota. Limnoperna modifies nutrient concentrations and decreases concentrations of particulate organic matter in the water column (including phytoplankto...
