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… Expand
Relationships of Limnoperna Fortunei with Benthic Animals
TLDR
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. Expand
Invasive mussels induce community changes by increasing habitat complexity
TLDR
This study explored the impact of the change in habitat complexity on benthic community created by druses of D. polymorpha and L. fortunei and found significant changes in species richness, density, biomass, taxonomic, and trophic structure of communities formed in druses compared to the nearby bare sediments.

The invasive freshwater bivalve Limnoperna fortunei in South America: multiannual changes in its predation and effects on associated benthic invertebrates
TLDR
Comparisons with a similar study carried out a decade earlier suggest that, after two decades of invasion, the reproductive potential of the mussel, the predation pressure on its colonies, and its facilitation effects on other invertebrates have increased in the Paraná River delta. Expand
Parallels and Contrasts Between Limnoperna fortunei and Species of Dreissena
TLDR
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. Expand
Fish predators of the golden mussel limnoperna fortunei in different environments in a south american subtropical river
TLDR
The degree of digestion of L. fortunei in the digestive tract of fish indicated that although most fish could digest this food resource, some Siluriformes found it difficult. Expand
Zebra versus quagga mussels: a review of their spread, population dynamics, and ecosystem impacts
TLDR
Because quagga mussels are found in all regions of a lake, and form larger populations, they may filter larger volumes of water and may have greater system-wide effects, especially in deep lakes, than zebra mussels, which are restricted to shallower portions of lakes. Expand
Fish vs. Aliens: predatory fish regulate populations of Limnoperna fortunei mitigating impacts on native macroinvertebrate communities
TLDR
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. Expand
Distribution and Colonization of Limnoperna fortunei: Special Traits of an Odd Mussel
TLDR
Man’s extensive modification of landscapes, in particular construction of reservoirs, large interbasin connections—canals and aqueducts and freshwater navigation was instrumental for the fast dispersal and success of a species that would otherwise have remained inconspicuous and restricted geographically. Expand
Ecology and Environmental Impact of Limnoperna fortunei: Introduction
TLDR
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. Expand
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 concentrationsExpand

The invasive bivalve Limnoperna fortunei enhances benthic invertebrate densities in South American floodplain rivers
TLDR
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. Expand
THE INVASIVE BIVALVES DREISSENA POLYMORPHA AND LIMNOPERNA FORTUNEI: PARALLELS, CONTRASTS, POTENTIAL SPREAD AND INVASION IMPACTS
TLDR
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. Expand
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 toExpand
THE EFFECTS OF DREISSENA POLYMORPHA (PALLAS) INVASION ON AQUATIC COMMUNITIES IN EASTERN EUROPE
TLDR
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. Expand
Changes in the distribution and abundance of Dreissena polymorpha within lakes through time
TLDR
Zebra mussel distribution within lakes was highly patchy, but the degree of dispersion decreased over time after initial colonization, which may be a result of saturation of suitable substrates by zebra mussels as populations increase and reach carrying capacity. Expand
Dispersion and Ecological Impact of the Invasive Freshwater Bivalve Limnoperna fortunei in the Río de la Plata Watershed and Beyond
TLDR
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. Expand
The Impact of Dreissena polymorpha (Pallas) Invasion on Unionid Bivalves
TLDR
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. Expand
The effects of the invasive mussel, Limnoperna fortunei, on associated fauna in South American freshwaters: importance of physical structure and food supply.
TLDR
It is concluded that the activity of living mussels is of major importance for controlling invertebrate numbers, biomass and diversity in South American rresnwaters. Expand
Significant ecosystem-wide effects of the swiftly spreading invasive freshwater bivalve Limnoperna fortunei
TLDR
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
TLDR
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. Expand
