The Living and Fossil Busycon Whelks: Iconic Mollusks of Eastern North America, is the seminal book on Busycon whelks, including all 17 living species and over 100 fossil species. The book contains over 120 color plates and maps with pictures of these fascinating shells. A trip to an open shoreline anywhere along the eastern United States will quickly introduce a beachcomber to the busycon whelks. These iconic American shells are abundant in shallow water areas from Cape Cod south to Florida and throughout the Gulf of Mexico, and are often the most conspicuous large mollusks to wash up onto beaches after storms. Although the busycon whelks are recognized as being one of the most conspicuous and common groups of marine mollusks in eastern North America, their systematic classification and taxonomic nomenclature was uncertain at best. Over the past 100 years, these iconic American mollusks have been placed in no fewer than four different families, underscoring the wide range of professional opinions regarding the systematic placement of this group. These families have included the Melongenidae, Busyconidae, Fasciolariidae, and the Buccinidae. In this book, the authors follow the requirement of total evidence, utilizing several busyconid classification tools, including classic morphological characters such as shell shape, protoconch structure, and periostracal structure, and also the evolutionary history, fossil record, and biogeographical patterns for each genus and species complex, and where available biochemical and DNA studies. These are all combined in different ways to gain insight into a more precise systematic placement of these large and important marine animals. The authors bring together as many aspects of busyconid biology and paleontology as possible, including an iconography of over one hundred color figures representing both the living and fossil species with distribution maps for each living species and subspecies. These data and color images give a higher-resolution view of the origins and evolutionary patterns of this important and iconic American molluscan family. 194 pp. num. color figs, hardcover 4.

Shallow water marine molluscan faunas are distributed in a pattern of distinct, geographically definable areas. This makes mollusks ideal for studying the distribution of organisms in the marine environment and the processes and patterns that control their evolution. This book is the first to use quantitative methodologies to define marine molluscan biogeographical patterns. It traces the historical development of these patterns for the subtropical and tropical western Atlantic. The book discusses the multistage process of evolving new taxa caused by eustatic fluctuations, ecological stress, and evolutionary selection. The authors define three western Atlantic provinces - Carolinian, Caribbean, and Brazilian - with 15 subprovinces. The text defines the physical aspects of the provinces using quantitative data, with water temperature as the primary parameter. The bulk of the molluscan biodiversity is concentrated in 40 separate centers of speciation, ranging from Cape Hatteras, North Carolina, south to Argentina. Many of these evolutionary hotspots reside on remote archipelagos and offshore banks as well as within areas of provincial overlap. The text describes some of the more exotic and poorly known areas and presents maps and color photographs of characteristic habitats, index species, and live animals, including over 400 species of rare and seldom seen shells. 234 pp., num. col. figs, num. maps, hc gr. 8.

In this book, a total of 103 fossil cone species are redescribed and presented on 30 figure plates, their time ranges are compared in a diagram, and two new genera are introduced (Herndliconus, p. 60, and Tequestaconus, p. 62). To each genus a picture of the type species is shown, and, wherever necessary, pictures of important conchological features are added after every description. As opposed to the "Compendium of Fossil Shells of Florida", Petuch & Drolshage, 2011, the shells on the figure plates are shown in true proportion, to give a visual overview of the dimensions of the single species in comparison to their congeners - an important distinguishing feature in identifying them. As a contribution to, and a summary of our present knowledge of fossil cones of southern Florida, this book represents the culmination of over 40 years of field research by the senior author. 179 pp., 30 color pls, num. text figs, hc 4.

Mollusks and Marine Environments of the Ten Thousand Islands provides the first comprehensive overview of the shells and habitats that are present in the last unexplored coastal area of southwestern Florida. The mysterious and primordial Ten Thousand Islands, where the rivers and marshlands of the Everglades empty into the Gulf of Mexico, house a number of remarkable marine ecosystems, many shown here in detail for the first time. Primary among these are unique worm shell "reef systems," composed entirely of immense masses of vermetid gastropod mollusks. These previously unexplored and unstudied gastropod reefs, which are often many acres in size, are shown here to mimic coral reefs in their growth structure and represent the only large-scale molluscan reefs found anywhere on Earth. Living in association with the zonated gastropod reefs are a number of rare and unusual mollusks, some of which represent endemic species that are unique to the Ten Thousand Islands. These and many other southwestern Florida shells are illustrated throughout this book, along with detailed illustrations and descriptions of the marine and estuarine environments that dominate the archipelago and its adjacent lagoon systems. 157 pp., num. color photographs, figs & maps, hardcover 4.

The Chesapeake Miocene will always be considered a paleontological treasure. Given the richness and accessibility of the Maryland and Virginia Miocene shell beds, it seems remarkable that very few people have ever described new species from these strata over the past 185 years. Until now. Integrating elements from paleontology, geology, environmental science, and ecology, Molluscan Paleontology of the Chesapeake Miocene assembles previous research and the authors' experience into a synoptic field guide. The most complete compendium of Miocene species created since 1904, this long-awaited resource lists nearly 500 species. It contains illustrations of 260 species, including more than 60 not found in any previous book and 26 newly discovered. It describes Chesapeake molluscan faunas in terms of local geology, paleoceanography, and marine paleobiology. Organized by stratigraphic geology, the book covers fossils of the Eastover, St Mary's, Choptank, and Calvert Formations. It illustrates 24 collecting sites and fossil exposures, showing details of in situ specimens, along with maps of 4 Miocene paleoseas and detailed stratigraphic columns for Maryland and northern Virginia. The text is accompanied by a CD-ROM with color illustrations of the forty known species of ecphora shells. Armed with these, you should be able to identify the species found in the amazingly rich shell beds of the Chesapeake Bay area. 168 pp, 60 b/w figs, hardcover gr. 8.

Molluscan Communities of the Florida Keys and Adjacent Areas: Their Ecology and Biodiversity is the first comprehensive overview of the ecology and biodiversity of the phylum Mollusca in the area of Florida extending from the Dry Tortugas and Ten Thousand Islands in the west to Palm Beach in the east. The book provides detailed analyses of molluscan faunas found in 20 different ecosystems, emphasizing the marine environments of the Florida Keys archipelago and its extensive coral reef tracts. Full-page color illustrations portray living animals, unique Keys environments, underwater ecosystems, and satellite images. More than 1,200 species of macromollusksin 86 gastropod families and 54 bivalve familiesare recorded from the study area, with color plates illustrating over 550 of the region's most ecologically important species. For the first time in any book on the malacology of the Florida Keys area, the 20 marine ecosystems and their associated molluscan assemblages are arranged by the CMECS (Coastal Marine Ecological Classification Standard) system. This system emphasizes the hierarchical relationships determined by substrate type, bathymetry, and water chemistry. Along with complete species lists for every molluscan assemblage, this handy guide introduces ten newly-discovered gastropods, including new species in the families Muricidae, Buccinidae, Nassariidae, Naticidae, Turritellidae, and Olividae. Two new bivalves in the families Pectinidae and Arcidae are also described in a special systematic appendix. This richly illustrated book is written for the professional scientific audience interested in mollusks, marine ecology, evolution, and taxonomy as well as malacologists, naturalists, and shell collectors. It is also an ideal synoptic field guide, showing where individual species of mollusks can be found and within which ecosystems they occur. 320 pp., 105 color figs, hardcover gr. 8.

Recent biodiversity studies, reported here for the first time, have shown that the molluscan fauna of the Gulf of Mexico is far richer and more complex than previously thought. As a result of these new discoveries, the Gulf malacofauna is shown to contain large numbers of endemic species that reside within four separate biogeographical subdivisions of the larger Carolinian Molluscan Province; the Floridian, Suwannean, Texan, and Yucatanean Subprovinces. These four Gulf biotic components, with each supporting its own endemic fauna, are shown here to be separated by distinct ecological and oceanographic barriers. The resultant physical and genetic isolation has led to the evolution of spectacular sibling species radiations, many unknown and undescribed until now. Some of the most conspicuous and important of these are found in the gastropod families Fasciolariidae, Volutidae, Conidae, Muricidae, and Busyconidae, all of which are dominant predators in their respective benthonic ecosystems. The species within these ecologically important families, along with hundreds of endemic taxa in 50 other gastropod and bivalve families, are illustrated here on 132 colour plates and are discussed in detail in the individual chapters. Special attention is given to the molluscs of poorly studied and virtually unknown ecosystems such as those on the deep reefs off the Florida Keys and Dry Tortugas, the deep water coralline algal beds off western Florida, the Flower Garden Reefs off Texas, the petroleum seeps and brine pools of the Sigsbee Escarpment, the Campeche Bank Archipelago, and the deep water areas at the mouth of the Yucatan Channel. This new book is unlike previous taxonomic surveys of the Gulf of Mexico molluscs in that it highlights only the endemic species and genera and does not cover the large number of widespread Carolinian and Caribbean taxa that occur with them. In this aspect, the book is designed to be an augmentation to previous faunal surveys, adding hundreds more taxa that had been missed in these older surveys or were described after those earlier works had been published. The emphasis on endemic species and species complexes is meant to underscore the special nature of the Gulf of Mexico malacofauna, setting it aside from all others in the Tropical Western Atlantic Region.

Marine biogeography, the study of the spatial distribution of organisms in the world's oceans, is one of the most fascinating branches of oceanography. This book continues the pioneering research into the distributions of molluscan faunas, first studied by biologists over 160 years ago. It illustrates 1778 species of gastropods in full color, many of which are extremely rare and poorly known endemic species that are illustrated for the first time outside of their original descriptions. CRC Press. 373 pp. with 203 color figs, hardbound 4.
