Book Description
One of the concerns over the invasion of zebra mussels in the Upper Mississippi River (UMR) system is the rapid colonization of these organisms in backwater regions with accompanying changes in water/sediment quality and habitat value. It is expected that zebra mussels will have a pronounced effect on the sediment and water column micro-environment after colonization. For instance, zebra mussels can graze seston (phytoplankton) and, because of their high densities, can filter water at tremendous rates, thereby transferring suspended particulate matter from the water column to the sediments (Reeders and de Vaate 1990). This process may have an important impact on food web dynamics, contaminant cycling, and water/sediment quality (Bruner, Fisher, and Landrum 1994; Effler and Siegfried 1994; Holland 1993; Leach 1993; Nichols and Hopkins 1993). Zebra mussel grazing also results in increased light penetration, which could affect epipelic community productivity (Griffiths 1993) and benthic trophic levels. Excretion of feces and pseudofeces on the sediment surface (Ten Winkel and Davids 1982) could, in turn, affect sediment chemistry and nutrient dynamics at the sediment-water interface. Thus, the colonization of zebra mussels on sediments in the UMR may affect ecosystem dynamics in backwater regions. This technical note summarizes research that was conducted to examine the changes in sediment and overlying water chemistry that occur due to zebra mussel colonization.
Zebra Mussels Biology, Impacts, and Control

Book Description
The introduction and rapid spread of the zebra mussel in North American waters has caused great concern among industrial and recreational users of these waters. This bivalve mollusk is a biofouler that attaches to any firm substrate (e.g. rocks, piers, water intake pipes, boat hulls) and has already created significant problems for raw water users such as water treatment plants and power plants. Zebra Mussels: Biology, Impacts and Control provides essential information regarding the biology of the zebra mussel in North America and Europe, presents case studies of environmental and industrial impacts, and outlines control strategies. Summary articles detail its life history, origins, and morphology. The book also examines techniques used to culture and maintain this organism in the laboratory. Thirty-two color plates illustrate some of the dramatic problems created by the explosive population growth of this species. Zebra Mussels: Biology, Impacts, and Control is an important resource for ecologists, conservationists, environmental consultants, water quality engineers, regulatory officials, power utilities, and libraries.

Book Description
Dense populations of zebra mussels (Dreissena polymorpha) have the potential to greatly impact water quality. By removing particulates and associated nutrients and contaminants from the water column and redistributing them to the sediments, zebra mussels affect water clarity, nutrient and contaminant cycling, and sediment quality. The purpose of this technical note describes potential changes in water quality as a result of zebra mussel infestations in aquatic systems, based on a review of the literature. The preliminary results of field studies to assess nutrient cycling are also presented. Important reference sources for more detailed information are listed at the conclusion of this technical note. Results of laboratory investigations to describe impacts at the sediment-water interface are presented in Technical Note ZMR-1-33.

Book Description
The introduction and rapid spread of two Eurasian mussel species, Dreissena polymorpha (zebra mussel) and Dreissena rostriformis bugensis (quagga mussel), in waters of North America has caused great concern among industrial and recreational water users. These invasive species can create substantial problems for raw water users such as water treatment facilities and power plants, and they can have other negative impacts by altering aquatic environments. In the 20 years since the first edition of this book was published, zebra mussels have continued to spread, and quagga mussels have become the greater threat in the Great Lakes, in deep regions of large lakes, and in the southwestern Unites States. Quagga mussels have also expanded greatly in eastern and western Europe since the first book edition was published. Quagga and Zebra Mussels: Biology, Impacts, and Control, Second Edition provides a broad view of the zebra/quagga mussel issue, offering a historic perspective and up-to-date information on mussel research. Comprising 48 chapters, this second edition includes reviews of mussel morphology, physiology, and behavior. It details mussel distribution and spread in Europe and across North America, and examines policy and regulatory responses, management strategies, and mitigation efforts. In addition, this book provides extensive coverage of the impact of invasive mussel species on freshwater ecosystems, including effects on water clarity, phytoplankton, water quality, food web changes, and consequences to other aquatic fauna. It also reviews and offers new insights on how zebra and quagga mussels respond and adapt to varying environmental conditions. This new edition includes seven video clips that complement chapter text and, through visual documentation, provide a greater understanding of mussel behavior and distribution.
