The invasive bivalve Limnoperna fortunei enhances benthic invertebrate densities in South American floodplain rivers
We assessed the effects of the introduced bivalve L. fortunei on the abundance and biomass of associated benthic invertebrates in South American large floodplain rivers. The survey was based on comparisons of L. fortunei-covered and L. fortunei-barren areas in five artificial cages from where large...
