Available in PDF, EPUB and Kindle. Book excerpt: Since current water quality models do not adequately portray population dynamics (Waide and Kennedy 1998), understanding the interactions between zebra mussels and water quality will require linking water quality models and models of zebra mussel population dynamics (Kennedy, Bridges, and O'Neill 1998). This technical note describes the development of a population model for zebra mussels. The model predicts probable population trajectories (changes in abundance over time) based on current abundances and information describing vital rates. A population is a group of individuals of the same species who, because they are located in the same geographic space, are able to locate each other and reproduce (Ackakaya, Burgman, and Ginzburg 1997). Population ecology is the study of the dynamics of populations while providing an information base upon which to discuss and evaluate many important natural resource management challenges (e.g., invasion of nuisance species, extinction of rare species). Population models account for changes in the number of individuals over time by considering factors that increase (i.e., birth and immigration) and decrease (i.e., death and emigration) abundance.
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.

Download or read book Population and Reproductive Dynamics of Zebra Mussels Dreissena Polymorpha in Texas Reservoirs written by Heather Mae Arterburn and published by . 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.

Available in PDF, EPUB and Kindle. Book excerpt: River networks are critically important ecosystems. This interdisciplinary book provides an integrated ecohydrological framework blending laboratory, field, and theoretical evidence that changes our understanding of river networks as ecological corridors. It describes how the physical structure of the river environment impacts biodiversity, species invasions, population dynamics, and the spread of waterborne disease. State-of-the-art research on the ecological roles of the structure of river networks is summarized, including important studies on the spread and control of waterborne diseases, biodiversity loss due to water resource management, and invasions by non-native species. Practical implications of this research are illustrated with numerous examples throughout. This is an invaluable go-to reference for graduate students and researchers interested in river ecology and hydrology, and the links between the two. Describing new related research on spatially-explicit modeling of the spread of waterborne disease, this book will also be of great interest to epidemiologists and public health managers.
