Species. Freshwater mussels are the most rapidly declining group of animals in North America. This guide represents a first-ofits-kind reference to assist both biologists and naturalists in the identification and study of freshwater mussels. Freshwater Mussels of Texas contains 224 pages with 226 black and white photographs, 144 color photographs and 79 line drawings covering all 52 species found in Texas waters. Introductory sections cover basic anatomy, reproduction.

Ducks in January . . . bats in March . . . rain lilies in April . . . meteors in August . . . the predictable appearance of fauna and flora allows humans to experience the natural cycles in the environment, no matter how urban the setting. In Nature Watch Austin, avid amateur naturalists Lynne and Jim Weber provide an introduction and guide to some of the natural events that define the seasons in the city of Austin and its surrounding areas. Month-by-month, each chapter profiles the plants, animals, insects, and other natural phenomena that are particularly noteworthy at that time of year. The authors also provide suggestions on how and where to see them—from driving to a nearby water treatment plant to lounging by the backyard bird feeder. Opening with a chart on weather, temperature, and daylight hours, each month’s chapter features photographs and original illustrations by the authors. A list of references includes area field guides and more in-depth sources of information by subject. No matter how clogged with traffic and entombed in concrete, even large cities harbor wildlife and support a community of plants, either in tucked-away places both familiar and unexpected, or in parks and preserves dedicated to city dwellers in search of open space. Learning the annual rhythms of “urban wildland” encourages everyone to be in tune with nature and welcome the opportunities to enjoy it, year after year.

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.

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

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.
