The First Edition of Ecology and Classification of North American Freshwater Invertebrates has been immensely popular with students and researchers interested in freshwater biology and ecology, limnology, environmental science, invertebrate zoology, and related fields. The First Edition has been widely used as a textbook and this Second Edition should continue to serve students in advanced classes. The Second Edition features expanded and updated chapters, especially with respect to the cited references and the classification of North American freshwater invertebrates. New chapters or substantially revised chapters include those on freshwater ecosystems, snails, aquatic spiders, aquatic insects, and crustaceans. * Most up-to-date and informative text of its kind * Written by experts in the ecology of various invertebrate groups, coverage emphasizes ecological information within a current taxonomic framework * Each chapter contains both morphological and taxonomic information, including keys to North American taxa (usually to the generic level) as well as bibliographic information and a list of further readings * The text is geared toward researchers and advanced undergraduate and graduate students

Pennak's Freshwater Invertebrates of the United States

Invertebrate Zoology deals with the animals that have no backbones, including the shrimps, crabs, sponges, worms, snails and squids. This book deals specifically with the invertebrates that spend all or part of their lifecycle in a freshwater environment. (As is usual and as in the previous edition, aquatic insects are excluded due to their vast numbers.) The invertebrate species far outnumber the vertebrate species, and a through understanding of aquatic invertebrate zoology is essential.

Ecology and Evolution of the Freshwater Mussels Unionoida

Unionoida (naiads) are characterized by larvae which have to pass through a parasitic stage on a host fish. Some of these host-parasite systems are unique, since the generation time of the parasite exceeds that of its host by a factor of ten. There is tremendous life history variation. With a life span of more than 200 years, some naiad species belong to the longest-lived invertebrates, some are highly host-specific, some are extremely fertile, some produce very peculiar larvae, and some occur at very high population densities. This volume describes and explains the characteristics and life histories of the naiads, the interactions with their hosts, and their evolution. It elucidates the manifold implications of their presence or absence in a lake or stream. Further, aspects of nature conservation are covered, as many naiad species are seriously threatened. Some have been used successfully as sensitive pollutant indicators in habitat monitoring and as "archives" for environmental changes.

"This fully illustrated book is a comprehensive, yet convenient and easy-to-understand guide to Florida's endangered and threatened animals and the habitats that support them. Chris Scott covers all 71 species, subspecies, or populations of mammals, birds, reptiles, fish, crustaceans, insects, corals, and mollusks. His species accounts describe each animal's listed status, identifying characteristics, historical and current distribution, biology, current threats, and conservation efforts.

The Art and Archaeology of Florida's Wetlands

Waterlogged archaeological sites in Florida contain tools, art objects, dietary items, human skeletal remains, and glimpses of past environments that do not survive the ravages of time at typical terrestrial sites. Unfortunately, archaeological wet sites are invisible since their preservation depends upon their entombment in oxygen-free, organic deposits. As a result, they are often destroyed accidentally during draining, dredging, and development projects. These sites and the objects they contain are an important part of Florida's heritage. They provide an opportunity to learn how the state's earliest residents used available resources to make their lives more comfortable and how they expressed themselves artistically. Without the wood carvings from water-saturated sites, it would be easy to think of early Floridians as culturally impoverished because Florida does not have stone suitable for creating sculptures. This book compiles in one volume detailed accounts of such famous sites as Key Marco, Little Salt Spring, Windover, Ft. Center, and others. The book discusses wet site environments and explains the kinds of physical, chemical, and structural components required to ensure that the proper conditions for site formation are present and prevail through time. The book also talks about how to preserve artifacts that have been entombed in anaerobic deposits and the importance of classes of objects, such as wooden carvings, dietary items, human skeletal remains, to our better understanding of past cultures. Until now this information has been scattered in obscure documents and articles, thus diminishing its importance. Our ancestors may not have been Indians, but they contributed to the state's heritage for more than 10,000 years. Once disturbed by ambitious dredging and draining projects, their story is gone forever; it cannot be transplanted to another location.

The Freshwater Mussels of Ohio

Nearly 200 years ago, 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 become 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. The Freshwater Mussels of Ohio by G. Thomas Watters, Michael A. Hoggarth, and David H. Stansbery brings together, for the first time, the most up-to-date research on Ohio's mussels. Designed for the weekend naturalist and scientist alike, it synthesizes recent work on genetics, biology, and systematics into one book. Each species is illustrated to a degree not found in any other work. Full-page color plates 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 a substantive introduction that includes information on basic biology, human use, and conservation issues. Extensive synonymies, a key to all species, and an illustrated glossary are included as well.

Freshwater Mussels in a California North Coast Range River

Occurrence, Distribution, and Controls

Freshwater mussels in California's rivers are potentially very useful as indicators of watershed health and recorders of watershed changes. We report the occurrence and habitat of mussel populations within a continuous 8-km section of the South Fork Eel River in the Northern Coast Range of California. The primary goals of our study were 1) to compile information on species composition and population density, and 2) to examine whether spatial distribution and variability were related to geomorphology and hydrology. We found numerous individuals of 2 species (Margaritifera falcata and Anodonta californiensis), with the spatial distribution of both species characterized by high variability. Mussels in this system live almost exclusively in pools (with a few in runs), near the channel banks, and especially among sedge root-mat substrate. High discharges almost certainly provide more of a constraint on the distribution and persistence of mussels in the South Fork Eel than do low summer flows, so we used the Hydrologic Engineering Center's River Analysis System (HEC-RAS) hydraulic model to estimate physical conditions during high flows when in-channel investigations were not feasible. In all flow regimes (summer, winter, 5-y flood, and the largest floods on record), mussels were found in areas of lower boundary shear stresses and lower velocities. Our study suggests that, at various spatial scales, mussels appear to be distributed in a manner that protects them from the highest flow-induced stresses.
