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. 

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.

 

 

"This is nature writing at its best." —E.O. Wilson

"Eloquent treatise...Landis's book is as much call to action as paean to mesmerizing molluscs." —Nature

"A lyrical love letter to the imperiled freshwater mussel." —Science

Abbie Gascho Landis first fell for freshwater mussels while submerged in an Alabama creek, her pregnant belly squeezed into a wetsuit. After an hour of fruitless scanning, a mussel materialized from the rocks—a little spectaclecase, herself pregnant, filtering the river water through a delicate body while her gills bulged with offspring. In that moment of connection, Landis became a mussel groupie, obsessed with learning more about the creatures’ hidden lives. She isn’t the only fanatic; the shy mollusks, so vital to the health of rivers around the world, have a way of inspiring unusual devotion.

In Immersion, Landis brings readers to a hotbed of mussel diversity, the American Southeast, to seek mussels where they eat, procreate, and, too often, perish. Accompanied often by her husband, a mussel scientist, and her young children, she learned to see mussels on the creekbed, to tell a spectaclecase from a pigtoe, and to worry what vanishing mussels—70 percent of North American species are imperiled—will mean for humans and wildlife alike. In Immersion, Landis shares this journey, traveling from perilous river surveys to dry streambeds and into laboratories where endangered mussels are raised one precious life at a time.

Mussels have much to teach us about the health of our watersheds if we step into the creek and take a closer look at their lives. In the tradition of writers like Terry Tempest Williams and Sy Montgomery, Landis gracefully chronicles these untold stories with a veterinarian’s careful eye and the curiosity of a naturalist. In turns joyful and sobering, Immersion is an invitation to see rivers from a mussel’s perspective, a celebration of the wild lives visible to those who learn to search.
