In soft sediments, Dreissena spp. create firm substrate in the form of aggregates of living mussels (druses) that roll free on the sediments. Druses provide physical structure which increases habitat heterogeneity, and the mussels increase benthic organic matter through the production of pseudofeces and feces. Descriptive and experimental studies were used to determine: 1) whether the density of benthic invertebrates in soft sediments increased in the presence of druses, and 2) whether the… 

Effects of an exotic bivalve mollusc on benthic invertebrates and food quality in the Ohio River

Isotope data suggest that detrital FBOM was not the sole food source for snails and amphipods in the authors' channels and that they were assimilating a higher quality portion of this BOM, which may depend on the response and/or susceptibility of those species to biofouling, increased habitat heterogeneity, and changes in the quality and quantity of nutrients.

Invasive mussels induce community changes by increasing habitat complexity

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.

Invasive ecosystem engineers on soft sediment change the habitat preferences of native mayflies and their availability to predators

The results suggest that by choosing Dreissena-covered habitat, Hexagenia receive protection from fish predation in turbid ⁄low light systems, as protection from predation cannot be the only reason hexagenia select Dreissenid mussels-covered sediments, ashexagenia selected for live clusters more often than empty clusters and may be a result of additional food resources.

The invasive freshwater bivalve Limnoperna fortunei in South America: multiannual changes in its predation and effects on associated benthic invertebrates

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.

The role of the zebra mussel (Dreissena polymorpha) in structuring macroinvertebrate communities on hard substrata

The results suggest that dense zebra mussel colonization alters macroinvertebrate communities on hard substrata by enhancing conditions for deposit-feeding organisms, small gastropods, and small predatory invertebrates, and by displacing large gastropod and certain large filterers.

Yellow Perch Foraging on Hexagenia spp.: Effects of Hypoxia and Dreissena

Two distinct mechanisms, one biotic and one abiotic, are examined that may affect whether or not burrowing mayflies select Dreissenacolonized habitat and hypoxia (low oxygen) may discourage use of Dreissena habitat because of already low oxygen levels are hypothesized.

Fouling mussels (Dreissena spp.) colonize soft sediments in Lake Erie and facilitate benthic invertebrates

Results from this study illustrate that physical disturbance directly limits the distribution of mussels on soft sediments, and the diversity and abundance of other benthic invertebrates in consequence.

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

Effect of Zebra Mussels, Dreissena polymorpha, on Macroinvertebrates in a Lake-outlet Stream

It is concluded that changes in macroinvertebrate community structure probably were related to the increased substrate complexity provided by zebra mussels.



Patterns in the Distribution and Abundance of Zebra Mussel (Dreissena polymorpha) in Rivers and Lakes in Relation to Substrate and Other Physicochemical Factors

Using SCUBA and an in situ method of quantifying substrate characteristics, patterns of zebra mussel distribution along the St. Lawrence and Hudson rivers and in Oneida Lake are described and empirical models for their abundance are developed.

Effect of filtering activity of Dreissena polymorpha (Pall.) on the nutrient budget of the littoral of Lake Mikolajskie

The effect of filtering activity of D. polymorpha on nutrient dynamics in Lake Mikolajskie depended mostly on population density: D. polymorpha was important in N and P cycling in periods when its

Food selection by Dreissena polymorpha Pallas (Mollusca: Bivalvia)

It is concluded that selection of different kinds of particle occurs in specific places in the mantle cavity, and not only does size-selection occur, but also selection of a chemical nature.

Zebra mussels : biology, impacts, and control

This book describes thirty years of studies of "dreissena polymorpha" pallas ecology in Mazurian lakes of northeastern Poland and the evolution and success of the heteromyarian form in the " dreissenoida".
