“…In terms of biomass, increases as high as 99% have been reported (Thayer et al, 1997;Stewart et al, 1998a, b;Stewart et al, 1999). It should be noticed that there also are some reports pointing at the opposite effect: that the presence of D. polymorpha has a negative impact on the invertebrate fauna (e.g., Nalepa et al, 1998;Lozano et al, 2001;Strayer & Smith, 2001), yet the overwhelming majority of the surveys do not support this conclusion.…”

The invasive bivalve Limnoperna fortunei enhances benthic invertebrate densities in South American floodplain rivers

2007

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 predators were excluded, exposed to colonization by the mussel for a total of 17 months in the lower Paraná river delta. Accompanying invertebrates were dominated by Oligochaeta, Nematoda, Rotifera, Copepoda, Gastropoda, Hirudinea, Chironomidae and nauplii. Also present in minor numbers were Tardigrada, Turbellaria, Cladocera, Ostracoda, Insecta, Hydracarina and Decapoda. Dominant invertebrates were 27-100% more numerous (and hosted 43-100% more biomass) in areas with L. fortunei than in areas barren of the mussel. In areas with L. fortunei, total invertebrate biomass (excluding the bivalve) was positively correlated with mussel biomass, and increased with time of exposure under water. No such trend was observed in areas barren of L. fortunei. 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. Some of the adverse ecosystem-wide effects of filter-feeding invasive mussels observed in European and North American water bodies may be offset in the Paraná by the extremely high loads of organic matter in these turbid waters.

“…Increase in the density of benthic invertebrates ranging from 38 to 90% and biomass as high as 99% were also observed in association with zebra mussel D. polymorpha presence, both in field manipulations and comparative studies (Silver Botts et al 1996;Ricciardi et al 1997;Thayer et al 1997;Stewart et al 1998Stewart et al , 1999aBially and MacIsaac 2000). Some studies (e.g., Nalepa et al 1998;Lozano et al 2001), however, have shown a negative impact of D. polymorpha beds on the diversity and density of benthic invertebrate fauna. All these examples suggest that increased bottom complexity and heterogeneity due to the presence of epibenthic bivalves usually, but not invariably, results in increased density, biomass and richness of associated fauna.…”

Non-indigenous invasive bivalves as ecosystem engineers

2009

Several non-indigenous bivalve species have been colonising aquatic ecosystems worldwide, in some cases with great ecological and economic impacts. In this paper, we focus on the ecosystem engineering attributes of non-indigenous invasive bivalves (i.e., the capacities of these organisms to directly or indirectly affect the availability of resources to other species by physically modifying the environment). By reviewing the ecology of several invasive bivalves we identify a variety of mechanisms via which they modify, maintain and/or create habitats. Given the usually high densities and broad spatial distributions of such bivalves, their engineering activities can significantly alter ecosystem structure and functioning (e.g., changes in sediment chemistry, grain size, and organic matter content via bioturbation, increased light penetration into the water column due to filter feeding, changes in near bed flows and shear stress due to the presence of shells, provision of colonisable substrate and refuges by shells). In addition, changes in ecosystem structure and functioning due to engineering by invasive bivalves often have very large economic impacts. Given the worldwide spread of nonindigenous bivalves and the varied ways in which they physically modify habitats, their engineering effects should receive more serious consideration in restoration and management initiatives.

“…The zebra mussel (Dreissena polymorpha Pallas) originates from the Caspian and Black Seas, but has invaded numerous European and North American inland waters (Strayer 1991), resulting in dramatic physical and biological changes (MacIsaac 1996). Especially in North American waters, invaded in the mid 1980s (Hebert et al 1989), zebra mussels have had a strong impact on ecosystem structure and function (Caraco et al 2006;Dermott and Kerec 1997;Lozano et al 2001;Mills et al 2003;Nalepa et al 1998) and long-reaching economic consequences (Connelly et al 2007;Khalanski 1997). Furthermore, zebra mussel invasions have caused the clogging of the water-intake of industrial and drinking-water plants, primarily in the USA (MacIsaac 1996).…”

Current and modeled potential distribution of the zebra mussel (Dreissena polymorpha) in Sweden

2009

In this study, we report the results from a recently performed survey of zebra mussel in Sweden and present a risk model for the potential distribution of the species. The zebra mussel was found in 11 of the 30 surveyed lakes and rivers. Most of the observations were made in the north-eastern parts of Lake Mälaren, i.e., in the basins Ekoln, Skarven, and Görväln. Hierarchical partitioning and stepwise selection of water chemistry variables in a multiple logistic model identified pH and magnesium concentrations as the best predictors for zebra mussel occurrence. We conjecture that magnesium is an important predictor due to its crucial role in mussel physiology. The logistic model was applied on 2,781 lakes and in total 109 lakes (3.9%), most of them situated in specific areas in central Sweden, in the very south and on the island of Gotland, were predicted to be potentially at risk for zebra mussel invasions. The lakes potentially at risk for zebra mussel invasions are separated by the soft-water boreal lakes that constitute the vast majority of lakes on the Fennoscandian peninsula, thus forming barriers for further dispersal.
