“…Besides being a particularly persistent invasive species, it is also a very effective ecosystem engineer, altering the invaded environments and outcompeting native species for food and space (Karatayev et al, 2002). D. polymorpha is a filterfeeding bivalve, capable of filtering large volumes of water while feeding mainly on algae, reducing plankton supply and increasing water clarity (Lindim, 2015;Mei et al, 2016). The increase in water clarity allows light to penetrate further in the water column and potentially promote an increase of benthic algae (Mei et al, 2016).…”

Species distribution modelling is a valuable tool for identifying areas most at risk of the spread of invasive species. Here we model the environmental factors governing the distributions of two invasive species of concern that are currently found in Sweden at only a limited number of locations: the aquatic macrophyte Elodea nuttallii (Nuttall’s waterweed / smal vattenpest) and the bivalve Dreissena polymorpha (Zebra mussel / vandrarmussla). For E.nuttallii, the greatest risk factors are connectivity with other water bodies (facilitating dispersion), human population density and length of growing season. This implies that it is principally well-connected lakes in populated areas of southern Sweden that are most at risk of further spread (although other areas of concern are identified). For D.polymorpha, water alkalinity and the proportion of agricultural land (a source of nutrient pollution) are the most important factors, and the models identify lakes Vänern and Vättern, waters in parts of Östergötland, Jämtland and Gotland as key areas of concern for further spread.

“…Higher water clarity can also increase the penetration of ultraviolet radiation affecting the survival or distribution of some organisms, induce changes in fish schooling, reproductive behavior, territoriality (Bunnell et al, 2021 ), and even modify temperature and dissolved oxygen vertical stratification patterns (Yu & Culver, 2000 ). While nutrient sequestration from the water column by invasive bivalves, especially in lakes, has been well documented, studies of changes in their concentrations (in particular P and N) in the water yielded quite dissimilar results, with both increases and decreases having been reported, as well as differences in the changes of their various compounds (see “ Nutrient cycling and sequestration ” section; Lindim, 2015 ), suggesting that these impacts are context-dependent.…”

Ecosystem services provided by the exotic bivalves Dreissena polymorpha, D. rostriformis bugensis, and Limnoperna fortunei

The ecosystem services approach to conservation is becoming central to environmental policy decision making. While many negative biological invasion-driven impacts on ecosystem structure and functioning have been identified, much less was done to evaluate their ecosystem services. In this paper, we focus on the often-overlooked ecosystem services provided by three notable exotic ecosystem engineering bivalves, the zebra mussel, the quagga mussel, and the golden mussel. One of the most significant benefits of invasive bivalves is water filtration, which results in water purification and changes rates of nutrient cycling, thus mitigating the effects of eutrophication. Mussels are widely used as sentinel organisms for the assessment and biomonitoring of contaminants and pathogens and are consumed by many fishes and birds. Benefits of invasive bivalves are particularly relevant in human-modified ecosystems. We summarize the multiple ecosystem services provided by invasive bivalves and recommend including the economically quantifiable services in the assessments of their economic impacts. We also highlight important ecosystem disservices by exotic bivalves, identify data limitations, and future research directions. This assessment should not be interpreted as a rejection of the fact that invasive mussels have negative impacts, but as an attempt to provide additional information for scientists, managers, and policymakers.
