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 macromollusks-in 86 gastropod families and 54 bivalve families-are 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.

This collection of conference papers presents information on the molecular genetics, biomineralization, growth and ecology of extant brachiopod stocks (extrapolated back to the Cambrian), and the shell microstructure, taphonomy, paleogeography, evolution, and taxonomy of fossil brachiopods.

The first half of this book is primarily a systematic survey of the snails, beginning with glossaries, keys for identification to genera and a checklist of species. This is followed by a synopsis of species, with brief notes on ecology, distribution and parasites. Relationships are then described between snails and schistosomes and with other parasites. The book goes on to consider the factors affecting snail populations and possible methods for population control.

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. Biogeography and Biodiversity of Western Atlantic Mollusks is the first book 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. Drawing on his decades of intensive field work, the author defines three western Atlantic molluscan provinces and 15 subprovinces based on his Provincial Combined Index, a modern refinement of Valentine's 50% rule. The faunal provinces-Carolinian, Caribbean, and Brazilian-are discussed in detail. The text defines the physical aspects of the provinces using quantitative data, with water temperature as the primary parameter. It discusses the details of the 15 subprovinces-geographically definable faunal subdivisions-as well as provinciatones, transition zones of provincial overlap. The author's algorithms demonstrate that 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.

The first comprehensive volume exclusively on marine cone snails, this book provides descriptions of over 100 species of hazardous marine snails along with their biological and ecological characteristics; the characteristics of conotoxins; information on cone snail injuries and their treatment along with prevention measures; and the therapeutic and medicinal value of conotoxins, including as a powerful nonaddictive painkiller, an epilepsy drug, and more. Over 275 color illustrations accompany the text for easy identification.

Biology and Management of Invasive Quagga and Zebra Mussels in the Western United States is a synthesis of the biology and management of invasive mussels from scientists and managers working on invasive quagga and zebra mussels in the western United States. Invasive dreissenid mussels have spread throughout southwestern United States at unprecedented speeds, and present a unique threat to native ecosystems. This book documents the efforts, both successful and unsuccessful, of individuals and agencies after dreissenid mussels invaded the West. Although the book is designed specifically for scientists and managers fighting invasive mussels in western waterbodies, it offers an opportunity for scientists and lake managers worldwide to compare successful strategies relevant to their unique situation. It includes guidance documents and protocols related to early detection, prevention, regulation, monitoring, and control of these invasive pests in the West. It compares quagga and zebra mussels in the western United States with those mussels colonizing the Great Lakes and European waters.

Members of the gastropod family Littorinidae are common throughout the world. They form a very abundant component of many intertidal and shallow subtidal ecosystems and, by their grazing, often play a central role in shaping these communities. They also display a wide range of life history strategies and many are polymorphic, making them attractive model organisms for ecologists, evolutionary biologists and physiologists alike. Areas of particular interest include ecological interactions with other animals and with algae, the effects of pollutants and the use of littorinids as sentinel species for monitoring pollution, the effects of parasites on growth and ecology, taxonomy, and the study of genotypic/phenotypic responses to environmental factors. There is still much to be done, and the Littorinids are proving to be an ideal group on which to work. The text is primarily targeted at the research level, but should also provide useful information for advanced first-degree students conducting research projects.

Bivalve mollusks are roughly hand-sized animals that can aggregate into large groups of millions of individuals as reefs-pumping and filtering enough water in short periods of time to control the processes on the reef and adjacent tidal waters-and serve as valuable indicators and monitors of ecosystem health. Ecology of Marine Bivalves: An Ecosystems Approach, Second Edition examines the ecology of bivalves from an ecosystem or holistic view, taking into consideration their history, thermodynamics, components, and interactions with other species-namely humans. With the advent of the United Nations Millennium Ecosystem Assessment (MEA) in the year 2000, its emphasis for utilizing the ecosystem approach as a standard guideline, and the growing interest in global climate change, this edition has been expanded to include: A new chapter on shell rings, which emphasizes the importance of interaction between disciplines so that we might learn from the past in order to plan for the future Scientific work done on several continents, including case studies from the Chesapeake Bay, the Wadden Sea, and other case studies from Europe and New Zealand Additional material on non-equilibrium thermodynamics, complexity theory, and other cross-disciplinary interactions This book discusses the roles of marine bivalves as a keystone species and as ecosystem engineers, and explains how bivalves are used as monitors and indicators of ecosystem stress and as a fisheries resource. Utilizing case studies and targeted published research to develop narratives suitable for a complex systems approach, the second edition of Ecology of Marine Bivalves is invaluable to scientists and marine workers interested in an up-to-date treatment of mollusks in our seas.

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.

The snails found living on rocky sea shores are among the most rewarding invertebrate animals to study. Species such as dog-whelks, topshells and winkles are easy to find, capture, identify, measure and mark. This book provides a key to common species, background ecology, an overview of rocky shore habitats and the techniques required for anyone to study this fascinating and accessible fauna.

Cephalopods are generally regarded as the most intelligent group among the invertebrates. Despite their popularity, relatively little is known about the range and function of their cognitive abilities. This book fills that gap, accentuating the varied and fascinating aspects of cognition across the group. Starting with the brain, learning and memory, Part I looks at early learning, memory acquisition and cognitive development in modern cephalopods. An analysis of the chambered nautilus, a living fossil, is included, providing insight into the evolution of behavioural complexity. Part II surveys environmental responses, especially within the active and learning-dependent coleoids. The ever-intriguing camouflage abilities of octopus and cuttlefish are highlighted, alongside bioluminescence, navigation and other aspects of visual and cognitive competence. Covering the range of cognitive function, this text underscores the importance of the cephalopods within the field of comparative cognition generally. It will be highly valuable for researchers, graduates and senior undergraduate students.

Originally published during the early part of the twentieth century, the Cambridge Manuals of Science and Literature were designed to provide concise introductions to a broad range of topics. They were written by experts for the general reader and combined a comprehensive approach to knowledge with an emphasis on accessibility. Pearls by W. J. Dakin was first published in 1913. The book presents a biologically-focused summary of the key facts regarding pearls, pearl fishing and pearl formation.

This book provides a comprehensive review of the ecology of freshwater bivalves and gastropods worldwide. It deals with the ecology of these species in its broadest sense, including diet, habitat and reproductive biology, emphasising in particular the tremendous diversity of these freshwater invertebrates. Following on from these introductory themes, the author develops a life history model that unifies them, and serves as a basis for reviews of their population and community ecology, including treatments of competition, predation, parasitism and biogeography. Extensively referenced and providing a synthesis of work from the nineteenth century onwards, this book includes original analyses that seek to unify previous work into a coherent whole. It will appeal primarily to professional ecologists and evolutionary biologists, as well as to parasitologists.

This book is perhaps the first attempt to comprehensively project the uniqueness of molluscs, covering almost all aspects of reproduction and development from aplacophorans to vampyromorphic cephalopods. Molluscs are unique for the presence of protective external shell, defensive inking, geographic distribution from the depth of 9,050 m to an altitude of 4,300 m, gamete diversity, the use of nurse eggs and embryos to accelerate the first few mitotic divisions in embryos, the natural occurrence of androgenics in a couple of bivalves, viable induced tetraploids, gigantism induced by elevated ploidy, the complementary role played by mitochondrial genome in sex determination by nuclear genes and the uptake and accumulation of steroid hormone from surrounding waters. In molluscs, sexuality comprises of gonochorism (< 75 %) and hermaphroditism, which itself includes simultaneous (> 24%), protandry (< 1 %), Marian and serial. In them, the presence of shell affords iteroparity and relatively longer life span in prosobranchs and bivalves but its absence semelparity and short life span in opisthobranchs and cephalopods. Within semelparity, gonochorism facilitates faster growth and larger body size but hermaphroditism small body size. In them, sex is irrevocably determined at fertilization by a few unknown genes and is not amenable to any environmental influence. However, the sex determining mechanism is more a family trait in bivalves. Primary sex differentiation is also fixed and not amenable to environmental factor but secondary differentiation is labile, protracted and amenable to environmental factors. Both sex differentiation and reproductive cycle are accomplished and controlled solely by neurohormones. In these processes, the role of steroid hormones may be alien to molluscs.

One of the most important sites for the early history of dyeing ever found in Minoan Crete was discovered in 2007. A Middle Bronze Age (Middle Minoan IIB) workshop for making natural dyes and using them to color fabrics included several basins carved into the soft limestone bedrock. Excavations uncovered pottery and stone vessels, stone tools, animal bones, and botanical remains among other types of artifacts. Pefka is of great importance for the history of Bronze Age technology as well as for the light it sheds on what was clearly a major Minoan industry. The evidence provides information both for the manufacture of dyes and for the broader issue of the economic foundation for Minoan trade in textiles during the period of the Old Palaces.

Freshwater mussels are declining rapidly worldwide. Propagation has the potential to restore numbers of these remarkable organisms, preventing extinction of rare species and maintaining the many benefits that they bring to aquatic ecosystems. Written by practitioners with firsthand experience of propagation programs, this practical book is a thorough guide to the subject, taking readers through the process from start to finish. The latest propagation and culture techniques are explored as readers follow freshwater mussels through their amazing and complex life cycle. Topics covered include the basics of building a culture facility, collecting and maintaining brood stock, collecting host species, infesting host species with larval mussels, collecting and culturing juvenile mussels, releasing juveniles to the wild, and post-release monitoring. This will be valuable reading for any biologist interested in the conservation of freshwater mussel populations.

With their large brains, elaborate sense organs and complex behaviour, cephalopods are among the world's most highly evolved invertebrates. This second edition summarises the wealth of exciting new research data stemming from over five hundred papers published since the first volume appeared. It adopts a comparative approach to causation, function, development and evolution as it explores cephalopod behaviour in natural habitats and the laboratory. Extensive colour and black-and-white photography illustrates various aspects of cephalopod behaviour to complement the scientific analysis. Covering the major octopus, squid and cuttlefish species, as well as the shelled Nautilus, this is an essential resource for undergraduate and advanced students of animal behaviour, as well as researchers new to cephalopods, in fields such as neuroscience and conservation biology. By highlighting the gaps in current knowledge, the text looks to inform and to stimulate further study of these enigmatic and beautiful animals.

Martin Lister, royal physician and fellow of the Royal Society, was an extraordinarily prolific natural historian with an expertise in shells and molluscs. Disappointed with the work of established artists, Lister decided to teach his daughters, Susanna and Anna, how to illustrate the specimens he studied. The sisters became so skilled at this that Lister entrusted them with his great work, 'Historiae Conchyliorum', assembled between 1685 and 1692. This first comprehensive study of conchology consisted of over 1,000 copperplates of shells and molluscs collected from around the world. 'Martin Lister and his Remarkable Daughters' reconstructs the creation of this masterwork, from the identification of the original shells to the drawings themselves, and from the engraved copperplates to the draft prints and final books. Susanna and Anna portrayed the shells not only as curious and beautiful objects, but also as specimens of natural history rendered with sensitivity and keen scientific empiricism. Beautiful in their own right, these illustrations and engravings reveal the early techniques behind scientific illustration together with the often unnoticed role of women in the scientific revolution.

Geerat Vermeij wrote this "celebration of shells" to share his enthusiasm for those supremely elegant creations and what they can teach us about nature. Most popular books on shells emphasize the identification of species, but Vermeij uses shells as a way to explore major ideas in biology. How are shells built? How do they work? How did they evolve? The author lucidly and charmingly demonstrates how shells give us insights into the lives of animals in our own day as well as in the distant geological past.

Cephalopods are fast-moving, voracious predators, and can change colour with breath-taking rapidity. They range from the giant squid, the world's largest marine invertebrate, to species of only 2 cm in length. Inhabitants of most seas of the world, they are found from the surface to great depths. Most cephalopods have short lives yet their efficiency in capturing and consuming prey ensures rapid growth. These animals possess highly-developed nervous systems, large brains, elaborate senses, complex behaviour and are capable of learning. Many of these features are described and illustrated with line drawings and photomicrographs.

Physiology of Molluscs: A Collection of Selected Reviews is an informative two-volume sent that brings together some of the most important recent and unique developments in molluscan physiology. Volume One focuses on shell structure, mineralization, the dynamics of calcium transport, shell drilling, byssus proteins, locomotion, and reproduction. Volume Two includes reviews on the neural mechanisms of learning, reproductive behavior, responses to environmental stress and hormones, and neurotransmitters. With the rapid development of cutting-edge proteomic, molecular biological, and cellular imaging techniques, our understanding of molluscan physiology, specifically in the areas of neurobiology, reproductive biology, and shell formation, has increased exponentially over the last several years. With contributions from some of the world's leading experts in the field of molluscan physiology, this valuable two-volume set fills this void and will serve as an important resource for researchers, professors, and students. Chapters report on a variety of recent developments and new understanding, including * biology of byssus threads * physiology of reproduction in cephalopods * learning and memory of molluscs * endocrine disruption in molluscs * nautilus biology and behavior * cephalopod locomotion * neuronal circuitry in molluscs * reproductive endocrinology * bioactive peptides in molluscs The reviews in these two volumes will make a significant contribution to our understanding not only of molluscan physiology but also the physiology of animals in general.
