The Mollusks by Charles F. Sturm,Timothy A. Pearce,Ángel Valdés Pdf
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.
Ecology and Classification of North American Freshwater Invertebrates by James H. Thorp,Alan P. Covich Pdf
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

Bivalve Seashells of Western North America. Marine Bivalve Mollusks from Arctic Alaska to Baja California by Eugene V. Coan,Paul Valentich-Scott,Frank R. Bernard Pdf
The culmination of a ten-year study, Bivalve Seashells of Western North America treats all bivalve mollusks living from northern Baja California, Mexico to Arctic Alaska. A total of 472 species are described and illustrated with detailed photographs and drawings. All habitats in the region are included from the intertidal splash zone to the abyssal depths of the ocean basins. The book has over 4,800 complete bibliographic references to the bivalves, including citations on the biology, physiology, ecology, and taxonomy of this commercially and biologically important group. Character tables and dichotomous keys assist the reader in identification. Also included in the 764 page book is an illustrated key to the superfamiles of the region, and a complete glossary.

Freshwater Mollusks of the World by Charles Lydeard,Kevin S. Cummings Pdf
The definitive resource on the biology and evolution of freshwater mollusks. There are more species of freshwater mollusks—well over 5,000—than all the mammal species of the world. Freshwater mollusks are also arguably the most endangered fauna on the planet. Yet few references exist for researchers, shell enthusiasts, and general readers who are interested in learning more about these fascinating creatures. In Freshwater Mollusks of the World, Charles Lydeard and Kevin S. Cummings fill that void with contributions from dozens of renowned mollusk experts. Touching on 34 families of freshwater gastropods (snails) and 9 families of freshwater bivalves (mussels and clams), each chapter provides a synthesis of the latest research on the diversity and evolutionary relationships of the family. The book also includes • a look at how evolving DNA sequencing data techniques help shed light on mollusk taxonomy • distribution maps of each family's biogeographic locales • a representative photo and distribution map for each of the freshwater mollusk families • the latest information on each family's conservation status—and how to reverse the habitat destruction, modification, and pollution that threatens it • a discussion of the ecological and economic damages caused by invasive mollusk species, as well as their role as disease vectors Mollusks provide us with amazing biogeographical insights: their ancient fossil record goes back over 500 million years, and their distribution patterns are a reflection of past continental and climate changes. The only comprehensive summary of systematic and biodiversity information on freshwater mollusk families throughout the world, this reference is a must for malacologists, limnologists, ichthyologists, stream ecologists, biogeographers, and conservation biologists.

Monitoring and Control of Macrofouling Mollusks in Fresh Water Systems, Second Edition by Gerald L. Mackie,Renata Claudi Pdf
Upon its initial publication more than fifteen years ago, this book broke new ground with its comprehensive coverage of the biology and ecology, distribution and dispersal mechanisms, physiology, monitoring, negative and positive impacts, and control of aquatic invasive species of mussels, clams, and snails. Building on this foundation, the second edition of Monitoring and Control of Macrofouling Mollusks in Fresh Water Systems includes completely revised information on species such as the zebra mussel while also covering up-and-coming nuisance species such as the quagga mussel, Conrad’s false mussel, the Asian clam, and the fast-spreading golden mussel. The Second Edition includes: Ten new species of mussels and snails International case studies on mussel fouling problems and how to cope with them New control and monitoring techniques Discussions of the latest threats and possible future scenarios The book contains brief descriptions of the external and internal structures, examining only those features relevant to the monitoring and control of the invasive species. It discusses why the mollusks are pests, distinguishing nuisance species from native species, their habits and habitat, reproductive potential, and life cycles and population dynamics. The authors also explain how efficient dispersal mechanisms employed by the nuisance mollusks not only help them spread so rapidly to inland lakes and rivers across continents, but how they can invade virtually every part of a facility. While many other resources contain segments of this information, none cover all areas and link them in a cohesive fashion. It is this approach that makes the understanding of potential impacts on ecosystems, industries and utilities, as well as the many human-made physical and chemical mitigants for controlling the mollusks supplied by this book so crucial for preserving the health of raw water supplies.

The Woodland Southeast by David G. Anderson,Robert C. Mainfort Pdf
This collection presents, for the first time, a much-needed synthesis of the major research themes and findings that characterize the Woodland Period in the southeastern United States. The Woodland Period (ca. 1200 B.C. to A.D. 1000) has been the subject of a great deal of archaeological research over the past 25 years. Researchers have learned that in this approximately 2000-year era the peoples of the Southeast experienced increasing sedentism, population growth, and organizational complexity. At the beginning of the period, people are assumed to have been living in small groups, loosely bound by collective burial rituals. But by the first millennium A.D., some parts of the region had densely packed civic ceremonial centers ruled by hereditary elites. Maize was now the primary food crop. Perhaps most importantly, the ancient animal-focused and hunting-based religion and cosmology were being replaced by solar and warfare iconography, consistent with societies dependent on agriculture, and whose elites were increasingly in competition with one another. This volume synthesizes the research on what happened during this era and how these changes came about while analyzing the period's archaeological record. In gathering the latest research available on the Woodland Period, the editors have included contributions from the full range of specialists working in the field, highlighted major themes, and directed readers to the proper primary sources. Of interest to archaeologists and anthropologists, both professional and amateur, this will be a valuable reference work essential to understanding the Woodland Period in the Southeast.
