Book excerpt: "Under the Species at Risk Act, Fisheries and Oceans Canada is responsible for the management of aquatic species at risk including freshwater mussels. Adaptive and responsive species management requires robust survey methods to answer management questions. To date, most of the survey method guidelines to monitor freshwater mussels in Canada have been developed for wadeable streams. However, there is a need to develop deep-water survey guidelines and protocols to ensure adequate protection for mussel species found in deep, turbid environments. This report summarizes the results from a literature review of freshwater mussel (Bivalvia: Unionidae) sampling methods and techniques used in deep, turbid, or high-flow environments. In total, 110 sources from primary and grey literature were reviewed"--Abstract, page iv.

Available in PDF, EPUB and Kindle. Book excerpt: Designing effective surveys for freshwater mussels (Unionidae) is a challenge, because they are spatially clustered and often found in low densities. The objective of this study was to examine how the effectiveness of three different survey methods (timed searches, transect method, and adaptive cluster method) varied between different habitats at six sites in the San Saba, Guadalupe, and San Antonio Rivers in Central Texas. Species richness, the total number of mussels per search effort, species composition and size distribution obtained with different survey methods were compared between sites. Timed searches were generally the most effective method in detecting species especially when densities were low (≤ 0.2 individuals per m2) or mussels were highly clustered. The adaptive cluster method, however, was as effective as timed searches in detecting species when densities were moderate or higher (>2 ind. per m2) and detected more species than timed searches at a site at which habitat conditions hindered searches. The performance of adaptive cluster in respect to number of mussels found per unit search effort seemed to be enhanced by sandy substrate facilitating the detection of mussels, and timed searches were less effective at sites at which habitat conditions hindered the detectability of mussels. Differences in detectability of mussels was not only associated with habitat conditions, but also with the size of mussels, their behavior and morphology. Timed searches detected a larger proportion of larger mussels that tended to be less burrowed and that had shells with more sculpturing compared to quantitative methods. In addition, surveyors with more search experience detected a larger number of mussels. Our results suggest that to design effective surveys variation in detectability of mussels must be considered which depends on local habitat conditions, experience of surveyor, behavior, size and morphology of mussels.
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 Sampling Adequacy of Freshwater Mussel Surveys and Variation of Mussel Species Richness in Illinois Wadeable Streams written by Jian Huang and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Freshwater mussels are one of the most imperiled groups of animals in North America. Effective conservation strategies and resource management of freshwater mussels require adequately characterizing local mussel assemblages. However, sampling protocols for mussel surveys, including sampling efforts, have not been well established and tested. Furthermore, the percentage of all species captured with a standard sampling effort (e.g., search of man-hours) may vary greatly among sites, introducing biases into our understanding of species-diversity patterns and temporal trends. In addressing both questions, I focused on time-based search, one commonly used sampling technique in stream mussel surveys in the present study. I sampled 18 wadeable-stream sites mainly in east-central Illinois, selected based on watershed size, dominant-substrate type, and historic species diversity. With 16 man-hour search per site, my sampling crew collected 27-942 individuals and 5-18 species per site. I estimated the total species richness at a site with Chao-1 method that accounted for imperfect species detectability. I measured sampling adequacy at a given effort as the % of all estimated species recorded. A frequently used effort, 4 man-hour search, captured 15-100% of all species with an average of 61%. Observed species richness was not significantly correlated with the estimated total richness until sampling effort reached 8 man-hours (Pearson0́9s r = 0.59, p
Download or read book Development of Standardized and Validated Survey Methods for Assessing Unionoid Mussel Assemblages in Missouri written by Leslie K. Lueckenhoff and published by . This book was released on 2015 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unionoid mussels are a highly imperiled faunal group that play an important role in the function and health of freshwater ecosystems. Habitat alteration due to anthropogenic influences led to dramatic losses in freshwater mussel diversity, making the long term monitoring and management of these organisms a priority for state and federal agencies. Missouri contains some of the most diverse mussel beds in the Midwest, but lacks a comprehensive monitoring framework for sampling unionoid mussel assemblages. Development of a standardized and validated sampling framework is essential for collecting precise and accurate data to facilitate informed management decisions and determine the success of implemented management plans. Sampling freshwater mussels in wadeable rivers often involves visual-based survey methods subject to multiple levels of bias. A baseline understanding of the ecological, behavioral, and habitat-mediated biases associated with multiple survey techniques is crucial for validation of a standardized sampling protocol. Validating standard methods allows assessment of the comparability of data collected between sites with spatial and temporal variability in assemblage composition and habitat conditions that could bias survey results. In this thesis, I focus on developing and validating standardized sampling techniques for assessing freshwater mussel assemblage-level metrics (e.g., species richness) over a range of habitat features in mid-sized, wadeable rivers in Missouri. The primary objectives are to: 1) determine how sampling technique and habitat features affect site-scale measures of species richness; 2) determine factors that affect site-scale measures of assemblage structure; and 3) determine the effect of sampling technique on species detectability, particularly low-abundant species. Five survey methods were implemented at 14 sites throughout the Meramec River Basin, which contains some of the greatest mussel diversity in the Midwestern United States. Results suggested that an extensive, qualitative survey method (timed visual search) detected a greater proportion of mussel species with consistently higher detection rates per unit effort than more intensive, quantitative methods. Measures of mussel assemblage structure varied by method due to greater effectiveness of extensive survey methods in detecting locally rare species. However, dominant species within mussel assemblages were detected similarly across all survey methods. Under the range of conditions examined in this study, habitat variables did not substantially affect how well methods detected species present in sites; however analysis identified water depth and site size as potential sources of bias. This study represents the first step in developing a standardized, validated sampling framework and will provide agencies tasked with managing and monitoring freshwater mussel assemblages with information to assist in choosing methods that best meet their project objectives.

Available in PDF, EPUB and Kindle. Book excerpt: Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.
Download or read book Freshwater Mussel Ecology written by David L. Strayer and published by Univ of California Press. This book was released on 2008-06-10 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pearly mussels (Unionoidea) live in lakes, rivers, and streams around the world. These bivalves play important roles in freshwater ecosystems and were once both culturally and economically valuable as sources of food, pearls, and mother-of-pearl. Today, however, hundreds of species of these mussels are extinct or endangered. David L. Strayer provides a critical synthesis of the factors that control the distribution and abundance of pearly mussels. Using empirical analyses and models, he assesses the effects of dispersal, habitat quality, availability of fish hosts, adequate food, predators, and parasites. He also addresses conservation issues that apply to other inhabitants of fresh waters around the globe and other pressing issues in contemporary ecology.

Available in PDF, EPUB and Kindle. Book excerpt: "The Freshwater Mussels of Tennessee . . . is indispensable to anyone, anywhere, working on this group. Parmalee and Bogan have written a work that sets the standard for future regional guides."--G. Thomas Watters, Ohio Biological Survey "The Freshwater Mussels of Tennessee documents a tremendously diverse and unique mussel fauna that is rapidly being destroyed by modern development. Parmalee and Bogan set a new standard for state mussel surveys in their authoritative, thorough, and and highly readable account. The book will be of interest to biologists and conservationists worldwide and will appeal to anyone who cares about the preservation of natural resources in the southeastern United States."--Robert E. Warren, Illinois State Museum With more than 150 species and subspecies recorded in the state, Tennessee has one of the most diverse freshwater mussel faunas in North America. Valuable as indicators of water quality, these mollusks have themselves become threatened as development encroaches on habitat--twenty-three are currently listed as endangered species and at least twelve have become extinct. This is the first book for Tennessee to deal with this biologically and commercially significant group of mollusks. Its authors have been studying and writing about the mussels of Tennessee for more than twenty years and have undertaken a systematic organization of a large and complex body of information to bring order to a difficult field. The book traces the long history of human exploitation of mussels, from aboriginal food gathering to the growth of the cultured pearl industry. It provides an interpretive context for its exhaustive species accounts with background material on biology, distribution, economic utilization, taxonomy, and conservation issues. The authors also review the life cycle of the mussel and describe its many remarkable traits, such as its shell formation and the strategies it employs during the larval stage in parasitizing fish. The species accounts comprise 128 members of Family Unionidae--from pigtoes and pocketbooks to lilliputs and spikes--plus four additional species. The authors cover classification and synonymy, range and distribution, life history and ecology, and survival status. Particular attention is paid to shell description and structure to assist the reader in identification. Each species account includes a distribution map and color photos of two specimens. The Freshwater Mussels of Tennessee is a major reference that encompasses historical and modern mussel collections and draws on conservation studies that span two centuries. It will stand as an authoritative guide to understanding Tennessee mollusks and as a benchmark in the study of these species worldwide. The Authors: Paul W. Parmalee is professor emeritus of zooarchaeology and director emeritus of the McClung Museum at the University of Tennessee, Knoxville. Arthur E. Bogan is curator of aquatic invertebrates at the North Carolina State Museum of Natural Sciences, Raleigh.
Download or read book A Handbook of Global Freshwater Invasive Species written by Robert A. Francis and published by Routledge. This book was released on 2012-03-12 with total page 918 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives. This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN. As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms. The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.

Book excerpt: Mollusks have been important to humans since our earliest days. Initially, when humans were primarily interested in what they could eat or use, mollusks were important as food, ornaments, and materials for tools. Over the centuries, as human knowledge branched out and individuals started to study the world around them, mollusks were important subjects for learning how things worked. In this volume, the editors and contributors have brought together a broad range of topics within the field of malacology. It is our expectation that these topics will be of interest and use to amateur and professional malacologists.
