Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: "The literature on zebra mussels and their effect on the Great Lakes ecosystem dates, of necessity, back only to the mid-1980's. This was when these exotic mollusks were introduced accidentally into Lake St. Clair, via ballast water dumped from a European vessel. The bibliography presented here combines the Great lakes literature with older European references dealing with the interaction of zebra mussels and their sediment substrate. It is intended as an aid for researchers into the associated processes and relationships"--Abstract, page 1.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2013 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive dreissenid mussels (zebra, Dreissena polymorpha and quagga, Dreissena bugensis), first identified in the western basin of Lake Erie in the late 1980s, have become a dominant factor in the structure of the Lake Erie food web and have the potential to cycle heavy metals to higher trophic levels through multiple pathways. The objectives of this study were to better understand the affect of dreissenid biodeposits on other benthic invertebrates through potential bioconcentration of heavy metals, and the subsequent bioaccumulation in amphipods (Gammarus). Laboratory experiments were designed to replicate natural conditions, allowing Dreissena to filter lake water and deposit feces and pseudofeces naturally within the druse structure, while natural sedimentation took place outside the druse. Sediment metal concentrations (Cd, Cr, Cu, Ni, Pb and Zn) exceeded US EPA Threshold Effect Levels (TEL) from both control and treatment traps (field experiment). Lake water concentrations of dissolved and particulate Cd, Cr, Cu and Ni (laboratory experiment) were found to be below levels determined to cause toxicity by the EPA. However, filtering by live dreissenid mussels resulted in elevated concentrations of heavy metals in sediments produced from feces and pseudofeces. Cadmium and chromium sediment concentrations in treatments (live mussels) were significantly higher than those in controls (dead mussels) (F1 = 13.5418, P = 0.0005 and F1 = 23.4032, P =

Available in PDF, EPUB and Kindle. Book excerpt: Zebra mussels, one of the most recent non-indigenous species to invade the Great Lakes, achieves extraordinary population densities in the lower lakes. They draw in water and filter a broad range of suspended particles, and have the potential to alter contaminant cycling in invaded lakes. They are also a conduit for contaminants and energy to higher trophic levels by serving as prey for fish and waterfowl. This study assesses the suitability of the zebra mussel as an organic contaminant biomonitor in the lower Great Lakes and also addresses its importance to waterfowl diets and body burdens or organocontaminants. It presents results of elimination rate determinations for polychlorinated biphenyl (PCB) congeners and contaminant levels in mussels from vaiours sites in Lake Erie and Lake St. Clair; results of experiments to determine the contribution of food to zebra mussel PCB accumulation; and statistical analyses of contaminant data for six species of ducks, examining differences in contaminant levels between those that consumed zebra mussels and those that did not.
Download or read book The Impact of Zebra Mussels Dreissena Polymorpha on Pelagic Food Webs written by Ruth Atkins Pontius and published by . This book was released on 2000 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: Zebra mussel feeding was restricted by reduced delivery of algae into the less-turbulent "concentration boundary layer" and by competition within the mussel colony for algae. I measured the relative magnitude of algal consumption by zooplankton in situ and by mussels in the lab relative to lake algal abundance and photosynthesis. Although seasonal phytoplankton successional patterns typical of north temperate lakes without zebra mussels have persisted after mussels became established in western Lake Erie, total phytoplankton biomasses were lower and Cyanobacteria rarer. However, changes in nutrient concentrations can account for shifts in algal species composition. Based on a comparison of primary productivity and algal standing crop phytoplankton were capable of reproducting once or twice a day. Grazing by free swimming, large-bodied crustacean zooplankton was sufficient to explain seasonal changes in algal abundance without considering zebra mussel impact at all. Even when seasonally abundant (maximum of 750 L-1 during August 1993), zebra mussel veligers grazed pelagic algae at an insignificant rate (generally 1- 3% with a maximum of 7.1%) relative to other zooplankton. Thus, potentially only the benthic adult zebra mussel stage with its larger biomass could be significantly impacting phytoplankton. Grazing by sedentary adult zebra mussels present in high densities was insufficient to overwhelm phytoplankton production.

This book was released on 2020 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Zebra mussels (Dreissena polymorpha) are highly invasive freshwater bivalve mollusks, introduced to the United Sates in the late 1980's, and known for forming dense colonies that can encrust boat hulls and motors, damage docks and marinas, and occlude raw water lines and intake pipes. In 2009, zebra mussels were discovered in Lake Texoma, TX/OK and have since infested twenty other lakes in Texas. Never before have zebra mussels been found in waters as warm as those in Texas, leading scientists, resource managers, and regulatory agencies to question the pervasiveness and persistence of this species in warm southwestern water bodies. To that end, this dissertation describes the results of a long-term study of zebra mussel populations in three Texas reservoirs with three main objectives: (1) assessing the mussel's population dynamics in warm water bodies by analyzing their growth rates, reproductive periods, and juvenile settlement patterns to elucidate the bases for observed zebra mussel population collapses; (2) examining the relationship between mussel veliger larva size and juvenile settlement and identifying possible temporal correlations between the presence of settlement-competent pediveligers in plankton samples with new juvenile settlement; and (3) evaluating the variation in the dry tissue weight of zebra mussels throughout the year in order to determine the impacts of elevated temperatures on body condition as a contributing factor to acute population declines. Collectively, this research will serve to better inform natural resource managers, aquatic ecologists, and those using raw water in developing management strategies, financial investments, and infrastructure changes to mitigate the consequences of zebra mussel invasion and fouling in warm southwestern United States water bodies.
