ABSTRACT In this study, for the first time, using similar methods, we compared the population density and distribution across different substrate types of Limnoperna fortunei and Dreissena polymorpha, as well as their impacts on the composition of benthic communities. Data on L. fortunei were obtained in Rio Tercero Reservoir, Argentina, whereas studies on D. polymorpha were conducted in North America and Europe. We found that, similar to the zebra mussel, L. fortunei creates high densities… 
Relationships of Limnoperna Fortunei with Benthic Animals
A variety of animals, including fish, crabs, turtles, waterfowl, and some mammals, may benefit from predation on this new abundant prey item, although the consequences to predator populations remain unstudied.
Parallels and Contrasts Between Limnoperna fortunei and Species of Dreissena
Future research on the golden mussel should focus on shedding light on the many unknown aspects of its biology and ecology, which are particularly critical for a comprehensive assessment of its interactions with local biota.
Fish vs. Aliens: predatory fish regulate populations of Limnoperna fortunei mitigating impacts on native macroinvertebrate communities
It was demonstrated that fish significantly reduce colonisation by L. fortunei (i.e. its density, biomass and body size), which may contribute to advancing towards using native fish as mitigating agents in reducing the native fauna.
Ecology and Environmental Impact of Limnoperna fortunei: Introduction
A growing body of evidence indicates that while these mussels are functionally similar, intrinsic and environmental differences are responsible for the fact that their impacts on the waterbodies colonized often differ significantly.
Effects of the Invasive Freshwater Mussel Limnoperna fortunei on Sediment Properties and Accumulation Rates
Since its introduction into South America around 1990, the freshwater bivalve Limnoperna fortunei (the golden mussel) has spread rapidly and is now a dominant component of the benthic and periphytic
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
Trichoptera (Insecta) in water hyacinth roots: evaluation of the influence of exotic mussel and environmental factors
It is suggested that the absence of the effects of the assessed L. fortunei in the community is related to the 'biotic resistance', in which the phytophylous caddisfly demonstrated adaptation to an environment characterized by hypoxic conditions in the dry season.
Nutrient Recycling, Phytoplankton Grazing, and Associated Impacts of Limnoperna fortunei
Laboratory and field experiments indicate that the presence of Limnoperna fortunei decreases concentrations of particulate organic matter and increases ammonia, nitrate, and especially phosphate.
Competitive Replacement of Invasive Congeners May Relax Impact on Native Species: Interactions among Zebra, Quagga, and Native Unionid Mussels
It is found that the frequency of unionid infestation by Dreissena recently declined, and the number of dreissenids attached to unionids in the lower Great Lakes has fallen almost ten-fold since the early 1990s.


The invasive bivalve Limnoperna fortunei enhances benthic invertebrate densities in South American floodplain rivers
It is suggested that higher invertebrate growth is associated with enhanced substrate complexity and, probably, the transfer of organic matter from the plankton to the sediments due to the mussels’ feces and pseudofeces in the lower Paraná river delta.
The golden mussel has broader environmental tolerances and therefore may be a much more successful invader than D. polymorpha in regions dominated by acidic, soft and contaminated waters.
The zebra mussel (Dreissena polymorpha) and the benthic community in a coastal Baltic lagoon: another example of enhancement?
The zebra mussel (Dreissena polymorpha), a sessile suspension feeder, has been known to enhance the benthos in the sediment around mussel beds and druses. The enhancement is mainly due to
Dreissena polymorpha has been invading fresh waterbodies of eastern and western Europe since the beginning of the 19th century and is still invading, and benthic invertebrate communities change dramatically in terms of total biomass, species composition, and relative abundance of functional groups.
Dispersion and Ecological Impact of the Invasive Freshwater Bivalve Limnoperna fortunei in the Río de la Plata Watershed and Beyond
It is suggested that the 2.4-fold increase in Argentine landings of freshwater fish between 1992–1993 and 2000–2001 may be associated with the introduction of this prey species, Limnoperna fortunei.
The Impact of Dreissena polymorpha (Pallas) Invasion on Unionid Bivalves
The correlation between overall Dreissena density and the number of zebra mussels per overgrown unionid, and the ratio of the mass of attached zebra Mussels to the massOf the host unionid is found.
Significant ecosystem-wide effects of the swiftly spreading invasive freshwater bivalve Limnoperna fortunei
The results indicate that the ecosystem-wide impacts of Limnoperna are generally comparable to those described in Europe and North America for another invasive mussel—Dreissena polymorpha; however, given Limniperna’s wider tolerance limits, its influence on newly invaded water bodies, potentially including Europe andNorth America, will probably be stronger.
Potential Impact of Filter-feeding Invaders on Temperate Inland Freshwater Environments
This review examines bivalve invasions in South America, summarizes the research results for two species, the Asian clam (Corbicula fluminea) and the golden mussel, and suggests further studies.
Functional Changes in Benthic Freshwater Communities after Dreissena polymorpha (Pallas) Invasion and Consequences for Filtration
Dreissena is extremely abundant in waters it invades, and dramatically changes benthic invertebrate communities in terms of total biomass, species composition, and the relative abundance of functional groups, which will alter the relative roles of the plankton and benthos in a variety of ecosystem functions.
Variable effect of a large suspension-feeding bivalve on infauna: experimenting in a complex system
In soft-sediment habitats there are many examples of species that modify their habitat and thus can be expected to have an important influence on macrobenthic community structure, but where multi-species interactions, indirect effects, non-linear biotic/abiotic interactions and threshold effects play an important role, specific experiments may not always lead to generalisable results, simply because the system is too complex.
