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 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.

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The zebra mussel is an invasive bivalve that was first confirmed in Kansas in 2003, and has decreased zooplankton abundance and altered the aquatic community in other areas where it has invaded. However, little is known about its effects on the aquatic communities of warm-water Great Plains reservoirs. We analyzed zooplankton, benthic macroinvertebrate, and juvenile and small-bodied fish abundance in the littoral zone of an Eastern Kansas reservoir with an established zebra mussel population (El Dorado Reservoir) and a control reservoir without zebra mussels (Melvern Reservoir) for two years pre-zebra mussel invasion (2001-2002) and two years post-invasion (2008-2009). We found no difference in littoral zooplankton abundance between reservoirs across time, but abundance of some macroinvertebrate taxa increased, and abundance of juvenile Lepomis spp. and red shiners decreased in the littoral zone of El Dorado Reservoir in August of the post-zebra mussel invasion period in comparison to the control reservoir. We also analyzed abundance and condition of six adult reservoir fishes in El Dorado Reservoir and three control reservoirs in Eastern Kansas for ten years pre-zebra mussel invasion (1993-2002) and five years post-invasion (2004-2008). Adult white crappie abundance remained constant in El Dorado Reservoir but decreased in the control reservoirs during the post-zebra mussel invasion period, and condition of adult bluegill, white bass, and white crappie decreased in El Dorado Reservoir in the post-zebra mussel invasion period compared to the control reservoirs. Our findings suggest that zebra mussel invasion in El Dorado Reservoir may have affected some benthic macroinvertebrates, juvenile and small-bodied fishes, and adult fishes. We did not find evidence that zebra mussels have had substantial effects on the zooplankton community of El Dorado Reservoir. However, July-August zebra mussel veliger densities in El Dorado Reservoir averaged less than 12 veligers/L in four of the six post-zebra mussel invasion years. Additional research and long-term monitoring of zooplankton, macroinvertebrates, and fishes will be necessary to determine the full effects of zebra mussels on the aquatic communities of warm-water reservoirs throughout North America.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The depth of the wind-mixed layer and diel thermoclines often determine the light climate of individual plankters, which, due to the random nature of turbulence can be different for plankters at the same depth. Time scales associated with photoresponse are often similar to various mixing time scales, on time scales of minutes to hours. I develop a method to estimate primary productivity, considering the effects of vertical turbulent mixing. The indirect temperature gradient microstructure method was used for calculating energy dissipation, from which I obtain Lagrangian diffusivity estimates. I then apply literature values of photosynthetic parameters (the slope and shape of the photosynthesis-irradiance curve) and a random walk simulation, using the diffusivity estimates, to predict the light climate of the phytoplankton and thus the primary productivity. I find that at some points in time and space, notably in early morning convective mixing, that photosynthesis may be underestimated by as much as 45%. However, diel thermocline formation reduces this effect, trapping algae near the surface and causing near surface declines in production. Separated from the source of mixing, the surface wind-shear, the lower water column primary production is still increased by more than 15% relative to the static model.
Download or read book Quantitative Fish Dynamics written by Terrance J. Quinn and published by Oxford University Press, USA. This book was released on 1999 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fields of fish population dynamics and stock assessment have seen major advances in the 1980s and 1990s, creating the need for a new synthesis. This text attempts that synthesis by presenting a contemporary approach for quantitative fisheries science that incorporates modern statistical and mathematical techniques. It emphasizes the link between biology and theory by explaining the assumptions inherent in the quantitative methods and models. The book covers key topics that are often overlooked in other texts, such as optimal harvesting, migratory stocks, and complex age and size-structured models. Quantitative Fish Dynamics is an ideal textbook for graduate and undergraduate courses in fish population dynamics and stock assessment. It is an indispensable reference work for fisheries scientists and others interested in conservation biology, fish and wildlife management, population ecology, and statistical applications.
Download or read book The Effects of Wetland Streams on the Secondary Dispersal of Zebra Mussels Dreissena Polymorpha in Connected Lake stream Systems written by Betsy L. Bodamer and published by . This book was released on 2007 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stream flow is a major vector for zebra mussel spread among inland lakes. I hypothesized that vegetated waterways, i.e. wetland streams, would hinder downstream dispersal of zebra mussels in connected inland lake systems. To test this hypothesis, veliger (larva) abundance, recruitment, and adult mussels were surveyed in four lake-wetland systems in southeastern Michigan, USA from May through August 2006. Sampling was conducted downstream of the zebra mussel invaded lakes, beginning at the upstream edge of aquatic vegetation and continuing downstream through the wetland streams. Results showed that veliger abundance decreased rapidly in vegetated waterways compared to their previously reported rates of decrease in non-vegetated streams. Veligers were rarely found more than 1 km downstream from where vegetation began. Newly recruited individuals and adults were extremely rare beyond open water in the study systems. These results suggest that densely vegetated aquatic ecosystems limit the dispersal of zebra mussels downstream from invaded sources. Natural, remediated and constructed wetlands may therefore serve as a protective barrier to help prevent the spread of zebra mussels and other aquatic invasive species to other lakes and ecosystems.
Download or read book The Freshwater Mussels of Ohio written by G. Thomas Watters and published by . This book was released on 2009 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the early nineteenth century, a naturalist named Rafinesque stood on the banks of the Ohio River and began to describe the freshwater mussels he found there. Since that time, these animals have earned a place among the most imperiled animals in North America. Dozens of species have become extinct, and it is estimated that two-thirds of the remaining freshwater mussels face a similar fate. Yet, despite their importance, the mussels of Ohio remain a poorly documented and largely mysterious fauna. This book compiles existing research on Ohio's mussels, synthesizing works on genetics, biology, and systematics into one volume. Full-page color images depict shell variation, hinge detail, and beak sculpture. Full-page maps show the distribution of each species based upon the collections of numerous museums, with historical distributions dating from the 1800s. In addition to species accounts, the book has an introductory section that includes information on basic biology, human use, and conservation issues.--adapted from jacket.
Download or read book Impacts of Zebra Mussels on Texas Unionid Mussels written by Ericah Beason and published by . This book was released on 2021 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Zebra mussels (Dreissena polymorpha) are an invasive species known to detrimentally affect native unionid mussels, a highly imperiled group of organisms. Zebra mussels infest (directly attach to) the shells of unionid mussels and compete with them for food as both unionid and zebra mussels are filter feeders. Previous studies, mostly from the northeastern US, have shown that both competition for food (indirect interaction) and zebra mussel infestation (direct interaction) can affect the body condition of unionid mussels. However, no study has examined this in Central Texas, the southern edge of zebra mussel distribution nor compared the impact of zebra mussel presence (in the same system as unionid mussels) and infestation (direct attachment to unionid mussel shells) on glycogen storage under controlled conditions. Hence, the objectives of this study were to 1) examine the impact of infestation versus presence of zebra mussels with experiments in the laboratory and 2) collect data on glycogen concentrations of unionid mussels at different field sites with and without zebra mussels. In the experiment, tissue samples were collected after 30 days from treatment tanks where 1) Threeridge (Amblema plicata) were artificially infested with zebra mussels, 2) zebra mussels were present with their biomass being comparable with the first treatment (44 ± 14 g wet biomass), but shells of A. plicata were not infested, and 3) control tanks where zebra mussels were absent. Tissue samples from A. plicata were collected from 20 individuals at each of the 10 field sites. Results from the experiments showed zebra mussel presence and infestation reduced glycogen 38% and 66% respectively. Results from the field supported these findings. Variation in glycogen concentrations of mussels collected in the field was best explained by chlorophyll-a concentrations (coarse measure of food resource) and total number zebra mussels. A larger percentage of infested mussels were burrowed in the lab experiment compared to control mussels, potentially to avoid unfavorable conditions created by both the presence and infestation of zebra mussels. Reduction of glycogen stores by zebra mussels can reduce short- and long-term fitness of unionid mussels which needs to be considered when creating and implementing management practices.
