This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies that differentiate between lake type or origin, i.e., natural lakes and reservoirs, or that focus solely on reservoirs are rare, especially at broad scales. These facts lead to reservoirs being less well understood compared to natural lakes. It is known that adding dams/impoundments alters the flow regime of the original water body and changes surface water connectivity. However, the impact of these alterations on invasive species dispersal is widely unknown. Reservoirs are also thought to have higher levels of human disturbance, which can provide opportunities for non-native species such as the zebra mussel (Dreissena polymorpha) to invade and establish. Surface water connections allow zebra mussel larvae to flow from one waterbody to another. Additionally, trailering of recreational boats among lakes can promote overland dispersal of zebra mussels through live wells and boating equipment. Although such connectivity promotes zebra mussel spread, we do not yet know how zebra mussels vary according to lake type nor the relative roles of surface and human connectivity and lake type. Taking a data-intensive approach at the macroscale, we ask: Are zebra mussels more common in reservoirs than in natural lakes? How does surface water and human connectivity influence the presence of zebra mussels in reservoirs and natural lakes? To answer these questions, we used 907 lakes within a 17-U.S. state extent and data from a variety of sources. Water quality, surface water connectivity, and human disturbance data were from the LAke multi-scaled GeOSpatial and temporal (LAGOS) database, public lake access sites were from the United States Geological Survey (USGS), and zebra mussel presence data were from the USGS Nonindigenous Aquatic Species database. We characterized surface water connectivity using six unique lake connectivity classes. We characterized human connectivity two ways: watershed road densities measured in meters per hectare and, for a 3-state subset of the study extent, the presence of public access sites on lakes. We characterized surface water connectivity using a lake connectivity classification based on lake and stream inflow(s)/outflow(s). Using logistic multiple regressions and controlling for region and lake chlorophyll a concentrations, we found that a higher proportion of reservoirs have zebra mussels compared to natural lakes for the 17-state extent. At this same spatial extent, we found that more highly connected lakes, both by humans and surface waters, were more likely to have zebra mussels present, regardless of lake type. Finally, at the 3-state extent, lakes with a public access site were more likely to have zebra mussels than those without, regardless of lake type. We conclude that not all 'lakes' are equally likely to have zebra mussels present and that both surface water and human connectivity are important predictors of zebra mussel presence. This study improves the understanding of how natural lakes and reservoirs differ and the extent to which reservoirs disproportionately harbor the invasive zebra mussel, which can improve management and prevention. For example, these results suggest that legislation and management focused on uninvaded reservoirs that are highly connected may help slow the spread of this invasive species.
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 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 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.

Download or read book Ecological Effects of Water level Fluctuations in Lakes written by Karl M. Wantzen and published by Springer Science & Business Media. This book was released on 2009-05-06 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most aquatic ecosystems have variable water levels. These water-level fluctuations (WLF) have multiple effects on the organisms above and below the waterline. Natural WLF patterns in lakes guarantee both productivity and biodiversity, while untimely floods and droughts may have negative effects. Human impacts on WLF have led to a stabilization of the water levels of many lakes by hydraulic regulation, untimely drawdown due to water use, or floods due to water release from hydropower plants in the catchments. This book provides a first review in this field. It presents selected papers on the ecological effects of WLF in lakes, resulting from a workshop at the University of Konstanz in winter 2005. Issues addressed here include the extent of WLF, and analyses of their effects on different groups of biota from microorganisms to vertebrates. Applied issues include recommendations for the hydrological management of regulated lakes to reduce negative impacts, and a conceptual framework is delivered by an extension of the floodpulse concept for lakes. Current impacts on water use, including increasing demands on drinking and irrigation water, hydropower etc., and climate change effects on WLF make this book an essential resource for aquatic ecologists, engineers, and decision-makers dealing with the management of lake ecosystems and their catchments.
Download or read book Ecology of Teleost Fishes written by Robert J. Wootton and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among the fishes, a remarkably wide range of biological adaptations to diverse habitats has evolved. As well as living in the conventional habitats of lakes, ponds, rivers, rock pools and the open sea, fish have solved the problems of life in deserts, in the deep sea, in the cold antarctic, and in warm waters of high alkalinity or of low oxygen. Along with these adaptations, we find the most impressive specializations of morphology, physiology and behaviour. For example we can marvel at the high-speed swimming of the marlins, sailfish and warm-blooded tunas, air-breathing in catfish and lungfish, parental care in the mouth-brooding cichlids and viviparity in many sharks and toothcarps. Moreover, fish are of considerable importance to the survival of the human species in the form of nutritious and delicious food of numerous kinds. Rational expoitation and management of our global stocks of fishes must rely upon a detailed and precise insight of their biology. The Chapman and Hall Fish and Fisheries Series aims to present timely volumes reviewing important aspects of fish biology. Most volumes will be of interest to research workers in biology, zoology, ecology and physiology but an additional aim is for the books to be accessible to a wide spectrum of non specialist readers ranging from undergraduates and postgraduates to those with an interest in industrial and commercial aspects of fish and fisheries.

Download or read book Freshwater Biodiversity written by David Dudgeon and published by Cambridge University Press. This book was released on 2020-05-21 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: Growing human populations and higher demands for water impose increasing impacts and stresses upon freshwater biodiversity. Their combined effects have made these animals more endangered than their terrestrial and marine counterparts. Overuse and contamination of water, overexploitation and overfishing, introduction of alien species, and alteration of natural flow regimes have led to a 'great thinning' and declines in abundance of freshwater animals, a 'great shrinking' in body size with reductions in large species, and a 'great mixing' whereby the spread of introduced species has tended to homogenize previously dissimilar communities in different parts of the world. Climate change and warming temperatures will alter global water availability, and exacerbate the other threat factors. What conservation action is needed to halt or reverse these trends, and preserve freshwater biodiversity in a rapidly changing world? This book offers the tools and approaches that can be deployed to help conserve freshwater biodiversity.
Download or read book Invasive Aquatic Species of Europe Distribution Impacts and Management written by Erkki Leppäkoski and published by Springer Science & Business Media. 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.
Download or read book Nonnative Oysters in the Chesapeake Bay written by National Research Council and published by National Academies Press. This book was released on 2004-03-09 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nonnative Oysters in the Chesapeake Bay discusses the proposed plan to offset the dramatic decline in the bay's native oysters by introducing disease-resistant reproductive Suminoe oysters from Asia. It suggests this move should be delayed until more is known about the environmental risks, even though carefully regulated cultivation of sterile Asian oysters in contained areas could help the local industry and researchers. It is also noted that even though these oysters eat the excess algae caused by pollution, it could take decades before there are enough of them to improve water quality.
