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.

This book was released on 2013-06-29 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: The global scale of alien species invasions is becoming more and more evident in the beginning ofthe new millennium. Though the problem ofbiological invasions became a rapidly growing research area, there are large gaps still, both geographically and the matically, to be filled in the near future. This book is the first attempt to provide an overall picture of aquatic species invasions in Europe. Its geographical scope stretches from Irish waters in the west to Volga River and the Caspian Sea in the east, and from Mediterranean in the south up to the Arctic coast of Europe. Not all parts of the continent could be equally covered, as in some countries species invasions are not studied yet. The book tends to represent the array of all major European aquatic systems on the broadest geographical and ecological scope possible from fully saline seas, semi-enclosed brackish water bodies and coastallagoons to freshwater lakes, major river systems and waterways. The key objectives include the present status and impacts caused by non-native aquatic species in European waters. Please note that lengthy species lists submitted for publication and additional informa tion were put on the Internet, as the electronical version of these tables benefits from computer assisted search for data (http://www. ku. lt/nemo/EuroAquaInvaders. htm). Altogether more than 100 scientists from 24 countries have joined to synthesize the available information on bioinvasions. However, the book does not claim to be fully comprehensive.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive species are a threat to global aquatic ecosystems. Nonetheless, their impacts can be heterogeneous across systems. Recent reports suggest Saskatchewan (SK) prairie lakes are highly prone to zebra and quagga mussels (ZQM) given their proximity to invasive corridors of Manitoba and three US states (Montana, North Dakota, and Minnesota) where they have been reported. As the effect of ZQM on native species is variable and context-dependent across locations and time, an understanding of prevailing biological, physical and chemical conditions supporting various cohorts of fish communities is necessary for prioritizing mitigation efforts to address the potential effects of these dreissenids in uninvaded systems. To gain these important insights, I investigated diet composition and body conditions of three ecologically and recreationally important gamefishes; walleye (Sander vitreus), northern pike (Esox lucius), and yellow perch (Perca flavescens) sampled from 18 SK prairie lakes. In addition, I assessed the impact of fish size and environmental variables on gamefish body conditions. Twenty-three prey taxa were found in the diets of these fishes. While both invertebrates (amphipods) and fish formed significant constituents of walleye diets, pike concentrated more on fish prey, whereas perch relied more on invertebrates (chironomids and amphipods). Zooplankton was only a minor contributor to the diets of all three gamefish species. Body conditions of walleye and pike decreased with size, but yellow perch populations were in consistently good condition across all size groups. These results suggest preferred fish prey of larger piscivores (i.e., pike and walleye) may be present in insufficient quantity. Lake productivity and alkalinity influenced body conditions of large-sized walleye and yellow perch. The scarcity of pelagic zooplankton prey in the diets of small-sized gamefishes implies these populations may be less threatened by future ZQM invasion than previously assumed. Next, I contrasted stomach content data and Carbon (C), Nitrogen (N), with Sulfur (S) stable isotope analyses to better quantify the relative importance of various foraging habitats to the three gamefish species. Bayesian Mixing models predicted that in about 70% of our study lakes > 55% of gamefish diets were sourced from the littoral region, whereas in ~30% of surveyed lakes, > 55% of gamefishes diets was sourced from the pelagic habitat. General evidence of similar reliance on sediment S sources in lakes where two species co-occurred (walleye and pike or walleye and perch) was observed. Overall, the three predominant gamefishes exhibited comparable dependence on the three feeding habitats (littoral, pelagic, sediment) across SK prairie lakes. Findings of stomach content analysis (SCA) and stable isotope analysis (SIA) were assessed to determine how the two techniques corroborate, contradict or complement each other. Results indicated a lack of correspondence between the two methods utilized in examining walleye diets, suggesting the need to use both techniques as complements for more robust results. Finally, because future invasion by ZQM is expected to significantly impact energy sources of gamefishes, I examined the current environmental controls of reliance on pelagic, littoral, and sediment-based diets. Walleye reliance on pelagic energy sources increased with the maximum depth of lakes and decreased with total dissolved solids (TDS) concentrations, implying the contribution of pelagic diets increase for fish populations in deeper and less saline lakes. However, sediment-based diets were not influenced by any of the selected environmental parameters. Integrating SCA and SIA overall helped to advance our understanding of feeding habits of gamefish populations in SK prairie lakes and demonstrates the value of combining these analyses for a comprehensive understanding of feeding interactions within aquatic ecosystems.

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.

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.
