Comparative Biology of Zebra Mussels in Europe and North America: An Overview

“…It is capable of monopolizing a considerable part of available energy through high filtering capacity and selective feeding on high-quality phytoplankton (MacIsaac 1996b, Mackie and Schloesser 1996, Naddafi et al 2007b). Zebra mussels cause considerable economic loss to electrical power plants and water treatment facilities, and can reduce plankton biomass, increase water clarity, alter phytoplankton species composition, increase macrophyte distribution, eradicate native bivalves, compete with resident species, modify nutrient cycling, change seston stoichiometry, alter energy pathways, and affect foodweb dynamics (MacIsaac 1996b, Naddafi et al 2008.…”

Abstract. The zebra mussel (Dreissena polymorpha) provides one example of successful invaders in novel environments. However, little attention has been devoted to exploring the factors regulating zebra mussel density and population size structure at the local scale. We tested effects of physicochemical factors and fish predation on the density of zebra mussels at several sites and between years in a natural lake. Water depth and roach (Rutilus rutilus) density were the most important variables affecting local zebra mussel density. Substrate was also an important factor but affected Dreissena density only at the shallowest depth examined (2 m), which also supported a large population of the mussels. Mean shell length of Dreissena increased with water depth. Our results indicate that predation pressure, intraspecific competition, and food limitation might be responsible for variation in zebra mussel density and population size structure in space and time and that fish predation might have strong top-down effects on zebra mussel populations.

“…However, Dreissena have vast dispersal potential owing to long-lived planktonic larvae (Mackie and Schloesser 1996;Mills et al 1996). As dispersal increased the range of lake sizes capable of supporting both species declined; patterns of species zonation were lost and a single species typically dominated the entire lake.…”

“…Both are benthic suspension feeders with diocy, broadcast spawning, and long-lived dispersing larvae (Mackie and Schloesser 1996;Mills et al 1996). Although similar in life history and ecology, they differ markedly in their patterns of spread.…”

Source-sink dynamics may be ubiquitous in ecology. We developed a theory for source-sink dynamics using spatial extensions of the net reproductive value, R 0 , which has been used elsewhere to define fitness, disease eradication, population growth, and invasion risk. R 0 decomposes into biologically meaningful componentslifetime reproductive output, survival, and dispersal-that are widely adaptable and easily interpreted. The theory provides a general quantitative means for relating fundamental niche, biotic interactions, dispersal, and species distributions. We applied the methods to Dreissena and found a resolution to a paradox in invasion biology-competitive coexistence between quagga (Dreissena bugensis) and zebra (D. polymorpha) mussels among lakes despite extensive niche overlap within lakes. Source-sink dynamics within lakes between deepwater and shallow habitats, which favor quagga and zebra mussels, respectively, yield a metacommunity distribution where quagga mussels dominate large lakes and zebra mussels dominate small lakes. The sourcesink framework may also be useful in spatial competition theory, habitat conservation, marine protected areas, and ecological responses to climate change.
