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.
Download or read book Quagga and Zebra Mussels written by Thomas F. Nalepa and published by CRC Press. This book was released on 2013-10-25 with total page 820 pages. 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.

Download or read book Shallow Lakes 98 written by Norbert Walz and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume combines articles on shallow lakes from leading European scientists in limnology. It covers aspects of the dynamics of macrophytes, phytoplankton, zooplankton and benthos, nutrient loading, littoral-pelagic interactions, and sediment-water interactions, as well as lake management. The object was not to separate theory (e.g. modelling) and management in order to generate new theories for the understanding of shallow lake ecosystems. The volume provides a comprehensive overview of the ecology of shallow lakes, a lake type which differs in prominent ways from deeper lakes. The broad spectrum of issues may also reflect the spectrum of interested readers such as limnologists, water engineers, hydrobiologists, who will be informed on a high level about new developments.

Download or read book Ecological Integration of Zebra Mussels in the Great Lakes written by Hugh Joseph MacIsaac and published by . This book was released on 1996 with total page 97 pages. 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 Zebra Mussels Biology Impacts and Control written by Thomas F. Nalepa and published by CRC Press. This book was released on 1992-11-24 with total page 848 pages. 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.
