The term neuroecology was first coined in the 1980s and describes the ways in which species adapt to their environment both in the short term and in evolutionary time. Here, we focus on molluscan neuroecology to show how it interfaces with neuroethology and how animal behaviour adapts to environmental cues. Neuroecology is thus meeting point between ethology, neuroscience, evolution, ecology, physics and chemistry. In this book, our contributors examine the concept of Neuroecology as applied to molluscs for the first time with particular reference to the areas of chemical ecology, predator prey relationships, neuroethology and evolution. Significant neuroecological progress has been made with a number of molluscan groups in terms of neurotoxic peptides, complex defensive ink alarm pheromones, bioaccumulation of shellfish toxins and the evolution of chemical defence mechanisms in species with reduced physical protection. Many molluscs inhabit a world of olfactory cues and their perceptions of the outside world are largely chemically driven, leading to odorant driven behavioural responses. This is important to both molluscan predators and prey and this area is explored in some detail with particular reference to gastropod molluscs. It is also true for cephalopod molluscs which although they have excellent vision, rely on distance chemoreception particularly prey perception, thus demonstrating their significance in affecting marine populations and communities.

Mussel is the common name used for members of several families of bivalvia mollusca, from saltwater and freshwater habitats. Mussels are economically and ecologically important as they play a key role in aquatic environments and are considered to be "ecosystem engineers." In this book, the authors discuss the ecology, life habits and control of mussels. Topics include native and invasive mussels; paralytic shellfish toxins and lipophilic toxins and their interaction with the habitat of mussels in the South Pacific Ocean; mussels as a tool to monitor pollution; bioenergetic model predictions of actual growth and allometric transitions during ontogeny of juvenile blue mussels; the synthesis of vitellogenin in the mussel mytilus galloprovincialis; the Brachidontes solisiannus mussel and its re-colonisation dynamics on a sandstone reef at Pernambuco, Brazil; and mussel farms in the Gulf of Naples.
This book brings together an international group of scientists focusing on present-day and fossil cephalopods, ranging broadly from Paleozoic ammonoids to today's octopods. It has three general sections dealing with: systematics and evolution; descriptions of hard- and soft part morphology; and ecology, biogeography, and taphonomy. Several highlights include new evidence for the existence of an ink sac in fossil ammonoids, a biogeographic study of clymeniid ammonoids throughout the world, the first record of a radula in baculite ammonoids, and an in-depth study of octopus ecology in Alaska. The book is remarkable in its treatment of both fossil and living forms at the same time, with the aim of presenting the wide diversity of cephalopods now and in the past.
This is the first book on molluscs as sources for pharmaceutical drugs. Marine molluscs are very promising candidates for a wide range of biotechnological applications. For example, they possess analgesic drugs more potent than morphine and very effective anticancer agents. International experts provide coverage of the most stimulating topics related to molluscs. This knowledge of their history and current studies opens the door to the future.
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.
The system of multicellular animals presented here is an alternative to the traditional classification system which still operates with the categories of Carl Linné, including typological divisions in artificial species groups. In a new approach to the phylogenetic order in nature this book strives for an objective systematization of the metazoa. It seeks a new path in the field of academic research and teaching based on the theory and methodology of phylogenetic systematics. This volume covers the metazoa from the Molluscs up to the Arthropods; the forthcoming volume 3 will cover all the remaining metazoa.
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.
"We have wasted our inheritance by improvidence and mismanagement."--William K. Brooks, on the Chesapeake Bay's declining oyster harvests, 1905 The Chesapeake Bay oyster has changed little, if at all, in the century since this popular book was published. But the oyster harvest has fallen to its lowest level on record--from 15 million bushels at the turn of the century to fewer than 100,000 bushels in 1993. What was once the most bountiful source of oysters in the world has become nearly exhausted. More than a century ago, explains Kennedy T. Paynter Jr. in the introduction to the present volume, scientist and Maryland state official William K. Brooks warned that this day would come. A classical morphologist by training, and one of the Johns Hopkins University's first and most distinguished faculty members, Brooks had "tonged oysters in five different states" when the governor of Maryland appointed him Oyster Commissioner in 1882. "The Oyster," first published in 1891, is a popular scientific account of what he knew and what he learned on the job. After describing the basic biology of the oyster, Brooks discusses its tremendous reproductive capacity, what it eats, how it lives, why it thrives in the Bay, and what role it plays in the Bay's ecology. But "The Oyster" is more than a simple biology text. It is also a critical scientific review of oyster management in the Chesapeake Bay, commenting on and criticizing contemporary laws and regulatory practices--many of which are still in place today. The book is therefore as timely now as it was when first published. A new introduction from Kennedy T. Paynter Jr. brings the story into modern focus and again charges the reader with the responsibility of caring for the life of the Bay.
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.
Stunning photographs make this guide to the seashells of Egypt's Red Sea coast a delight for scientists and beachcombers alike. Biologist Mary Lyn Rusmore-Villaume offers succinct descriptions of over five hundred species, indicating geographic range, size, color, and other details. The book is organized by taxonomy, divided between gastropods and bivalves, and each species is illustrated with one or more photographs for easy identification, all taken especially for this book by the author using shells from her own collection. All the shells most people are likely to see are included here, as well as many rare specimens (including an entirely new species discovered by the author). The species covered come from all regions of Egypt bordering the Red Sea, including the Gulf of Suez, South Sinai, the Gulf of Aqaba, and the mainland coast from Hurghada to Shalatein. As the only guide to Egypt's Red Sea shells, this is an invaluable reference for anyone interested in the Red Sea and its rich biodiversity. Copiously illustrated and comprehensive in its approach, "Seashells of the Egyptian Red Sea" represents a unique contribution to the scientific knowledge of the marine fauna of this branch of the Indo-Pacific region.
The Utah Mollusk Identification Guide offers up-to-date information for identifying aquatic and terrestrial snails, slugs, clams, and mussels within the state of Utah, providing comparative tables, taxonomic keys, and more than 230 images, including many type specimen images published for the first time. Amateur naturalists and biologists alike will benefit from detailed information regarding size, type, specimen location, junior synonyms (including taxonomy notes), original descriptions for each of the 139 species, and comments to help differentiate similar species. In contrast to older guides, this book includes data on the external and internal anatomy of mollusks. Taxonomic names are updated to incorporate the latest information available. Family descriptions and miscellaneous data on ecology, life history, and genetics are also presented. Distribution data are based on historical articles, museum records, personal observations, and collections. Although the focus is on Utah mollusks, many species are widely distributed and the data, images, references, and taxonomy details within the guide will be of interest to many outside the state.
Pearly mussels (Unionoidea) live in lakes, rivers, and streams around the world. These bivalves play important roles in freshwater ecosystems and were once both culturally and economically valuable as sources of food, pearls, and mother-of-pearl. Today, however, hundreds of species of these mussels are extinct or endangered. David L. Strayer provides a critical synthesis of the factors that control the distribution and abundance of pearly mussels. Using empirical analyses and models, he assesses the effects of dispersal, habitat quality, availability of fish hosts, adequate food, predators, and parasites. He also addresses conservation issues that apply to other inhabitants of fresh waters around the globe and other pressing issues in contemporary ecology.
"Ponder and Lindberg provides a breathtaking overview of the
evolutionary history of the Mollusca, effectively melding
information from anatomy, ecology, genomics, and paleobiology to
explore the depths of molluscan phylogeny. Its outstanding success
is due to thoughtful planning, focused complementary contributions
from 36 expert authors, and careful editing. This volume is a must
for malacologists."--Bruce Runnegar, Department of Earth and Space
Sciences, University of California, Los Angeles
The authors argue that the growth pattern and form of the colony in many bryozoans is an adaptive strategy rather than a stable genetic character. "Bryozoan Evolution is profusely illustrated and has a bibliography of over 400 titles. It will find an appreciative audience of paleontologists, invertebrate zoologists, and ecologists thanks to its innovative and detailed evaluations of the roles of ecology, adaptive and functional morphology, life histories, biomechanics, developmental constraints, and chance on the evolution of the marine taxa of this speciose group."--Russel L. Zimmer, Science "This book is an excellent source of information on the functional morphology and variety of colonial architecture in bryozoans, very well illustrated, and worth reading at least twice."-Robert L. Anstey, Paleobiology "Even as one of the converted, I found the book a stimulating combination of paleobiology and ecology. In many ways it is a 'teaser'-the authors suggest a number of interesting hypotheses, and can test only some of them. Perhaps most important, McKinney and Jackson provide a plethora of fascinating ideas and examples that demonstrate the potential of this group of animals, and that should stimulate more work."-Michael S. Keough, TREE "This stimulating book is sure to promote further interest in bryozoans. It will appeal to biologists and paleontologists alike."-Paul Taylor, Times Higher Education Supplement
This book identifies all valid species belonging to the superfamily Mactroidea living in American waters, distributed across fourteen biogeographical provinces. It also provides an updated classification of the widely occurring Mactroidea superfamily, which comprises eight subfamilies grouped into four families: Mactridae (Lamarck, 1809); Anatinellidae (Deshayes, J.Gray 1853); Cardiliidae (Fischer, 1887) and Mesodesmatidae (J. Gray, 1840). The species included in this superfamily are known to have existed in North America since the Early Cretaceous.
Written during a long sea voyage from England through the Mediterranean, "Civilization and the Limpet" unveils many fascinating phenomena of undersea life. Wells captures with exquisite detail how limpets, like bees, navigate by the stars; how the brainless sea urchin makes a myriad of critical survival decisions every day; how "deserted islands" teem with an incredible abundance of animal life; and why deep-diving whales never get the bends. Elegant and finely crafted, "Civilization and the Limpet" will enlighten, amuse, and awe anyone interested in the natural world.
Lucid line drawings and photos, 16 in fine color. Based on some 15 years of study and collection in both polar regions and most areas of the tropics and temperate zones. Detailed treatment is given on all known pelagic snails (aoubt 140 species) including: external anatomy, swimming and buoyancy mec
During the 1950s, 60s, and early 70s, California's coast seemed awash in abalone. From San Diego to Crescent City, people feasted on abalone steaks and glimmering shells were sold in trinket shops. Abalones' remarkable abundance and appeal made them icons of California's easy-living, laid-back beach culture. But just a few decades later, many younger Californians had never seen the legendary mollusk. In the past twenty years, two of California's seven abalone species have joined the U.S. Endangered Species list, and even the hardiest now faces the ecological collapse of its home habitat in Northern California - long regarded as a sure stronghold. After more than 70 million years of gripping tenaciously to North America's western shoreline, how - in our time - did the fate of the delicious, wondrous, and once abundant abalone become so precarious?
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.
Freshwater Mussels of Florida is the only comprehensive, illustrated encyclopedia of all recorded species of mussels in the state on Florida. 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.
In Mexico's western Sonoran Desert along the Gulf of California is
a place made extraordinary by the desert solitude, the dynamic sea,
and the people who live there--the Seris. Central to the lives of
these people are the sea and its shores. |
