Alabama rivers and waterways are home to the largest and most diverse population of freshwater mussel species in the nation, roughly 60% of U.S. mussel fauna. The Mobile River Basin, which drains portions of Tennessee, Georgia, and Mississippi waterways, also contains diverse mussel populations. However, many of these species have been significantly depleted in the last century due to habitat alteration (river damming, channelization, siltation), pollution, and invasive species, and many more are in imminent danger of extinction.

The authors offer encyclopedic entries on each of the 178 mussel species currently identified in Alabama and the Mobile River Basin—the scientific and common names; a morphological description as well as color photographs of the shell appearance; analysis of the soft anatomy; information about ecology, biology, and conservation status; and a color distribution map. With an extensive glossary of terms and full index, plus additional material on the archaeological record, a history of commercial uses of mussels, and the work of significant biologists studying these species, this volume is a long overdue and invaluable resource, not only for scholars of aquatic biology and zoology but also conservationists interested in the preservation of ecological diversity and protection of inland environments.

An exhaustive guide to all aspects of the freshwater mussel fauna in Florida, Freshwater Mussels of Florida covers the ecology, biology, distribution, and conservation of the many species of bivalve mollusks in the Sunshine State. In the past three decades, researchers, the public, businesses that depend on wildlife, and policy makers have given more attention to the threatened natural diversity of the Southeast, including freshwater mussels. This compendium meets the increasingly urgent need to catalog this imperiled group of aquatic organisms in the United States.
 
Each entry in this definitive guide provides a detailed description and multiple depictions of the species as well as select characteristics of its soft anatomy and miscellaneous notes of interest. Individual distribution maps pinpoint the historical and present occurrence of each bivalve species and are just one component of the rich set of 307 mussel and habitat photographs, seventy-four maps, and thirteen tables that illustrate the book. Of particular interest are remarkable electron micrographs of glochidia, the specialized larval life history stage parasitic upon fishes.
 
Freshwater Mussels of Florida will be of lasting value to state and federal conservation agencies as well as other government and nongovernment entities that manage aquatic resources in Florida. The research provides a key baseline for future study of Florida mussels. The survey results in this guide, along with extensive reviews of historical mussel collections in natural history museums, provide a complete picture of the Florida mussel fauna, past and present.
