Bivalve molluscs are abundant in marine and freshwater ecosystems and perform important ecological functions. Bivalves have epifaunal or infaunal lifestyles but are largely filter feeders that couple the water column and benthos. Bivalve ecology is a large field of study, but few comparisons among aquatic ecosystems or lifestyles have been conducted. Bivalves impact nutrient cycling, create and modify habitat, and affect food webs directly (i.e., prey) and indirectly (i.e., movement of…

Filter-feeders have differential bottom-up impacts on green and brown food webs
It is suggested that nutrient regeneration by mussels most strongly regulates green food webs, with some impacts to brownFood webs, suggesting that consumers have interactive effects on microbial functioning in freshwaters.
Restoring tropical coastal wetland water quality: ecosystem service provisioning by a native freshwater bivalve
Freshwater bivalves can influence water quality by reducing phytoplankton levels through filter-feeding and altering nutrient levels through excretion and biodeposition. In northeast Australia,
A Facilitation Cascade Enhances Local Biodiversity in Seagrass Beds
It is found that pen clam density and survivorship was significantly greater in seagrass beds, indicating that eelgrass facilitates pen clams, and hypothesize that functioning may more likely be enhanced in scenarios where secondary foundation species specifically increase the diversity of key functional groups such as epiphyte grazers and/or when bivalves are infaunal rather than epifaunal.
Mass Mortality Events of Invasive Freshwater Bivalves: Current Understanding and Potential Directions for Future Research
Impacts on biological communities (bacteria, fungi, and macroinvertebrates) are less studied but some examples exist concerning C. fluminea.
Effects of Corbicula fluminea on the nutrient concentration and phytoplankton biomass of tropical reservoirs
Invasive bivalves are known to negatively impact aquatic ecosystems across the globe. Previous research has demonstrated invasive bivalves can shift nutrients from the water column to the sediment,
Ancestral Physical Stress and Later Immune Gene Family Expansions Shaped Bivalve Mollusc Evolution
The ability of bivalves to tolerate high levels of environmental stress and constant exposure to pathogens as filter feeders is reflected in the conserved expansion of protein recycling gene families found across bivalvia.
Mussels and Local Conditions Interact to Influence Microbial Communities in Mussel Beds
Microbiomes are increasingly recognized as widespread regulators of function from individual organism to ecosystem scales. However, the manner in which animals influence the structure and function of


Transformation of Freshwater Ecosystems by Bivalves A case study of zebra mussels in the Hudson River
It is shown that bivalves are in fact dominant filterfeeders in many shallow-water ecosystems, and human activities often radically alter the density and composition of bivalve communities, in so doing inadvertently transforming ecosystem structure and function.
The functional role of native freshwater mussels in the fluvial benthic environment
Examination of the functional role of Margaritifera falcata in the South Fork Eel River, California shows that mussels can play a significant role in local food webs by increasing available fine particulate matter on the substrate.
Effects of Bivalve Aquaculture on the Environment and Their Possible Mitigation: A Review
The purpose of this article is to present a review of the effects of bivalve aquaculture on the surrounding environment and the current mitigation strategies, and to highlight how the same natural characteristics ofbivalves can positively interact with the environment.

Ecosystem services are the benefits that humans derive from ecosystems. Freshwater mussels perform many important functions in aquatic ecosystems, which can in turn be framed as the ecosystem
Impacts of Zebra Mussels on Aquatic Communities and their Role as Ecosystem Engineers
Zebra mussels (Dreissena polymorpha) are not only an extremely aggressive invasive species, often dominating water bodies they invade, they are also very effective ecosystem engineers, altering the
Biodiversity Losses and Ecosystem Function in Freshwaters: Emerging Conclusions and Research Directions
Six conclusions have emerged from recent research that complicate the ability to predict how biodiversity losses may affect ecosystem function: species traits determine ecosystem function, species within functional groups are not always ecological equivalents, and successfully predicting linkages between biodiversity and ecosystem function requires using multiple empirical approaches across scales.
Understanding how nutrient cycles and freshwater mussels (Unionoida) affect one another
It is suggested that nutrient loads are related to the well-being of mussels populations through several mechanisms, probably producing a nonlinear and non-monotonic relationship between nutrient loads and mussel populations.
Potential indirect effects of shellfish culture on the reproductive success of benthic predators
The potential for significant bottom-up effects of aquaculture on surrounding ecological assemblages is demonstrated and, as has been suggested, sperm limitation is a major constraint on recruitment of asteroids and other invertebrate predators, supplemental provisioning from increased farm development could result in occasional outbreaks of populations.
What a difference a species makes: a meta–analysis of dreissenid mussel impacts on freshwater ecosystems
A meta-analysis of published studies and long-term monitoring data sets evaluated the effects of dreissenid mussels on the biogeochemistry, flora, and fauna of lakes and rivers across North America and Eurasia to find the largest effects were found in rivers, followed by littoral and pelagic habitats in lakes.
