Book Description
Molecular Aspects of Bioelectricity describes the self-organization in molecular and cellular networks. This book evaluates the chemical representation of ion flux gating in excitable biomembranes and addresses the theoretical implication of liganding reactions in axonal sodium channel gating. It also strongly demonstrates the ligand interactions of crustacean axonal membrane. The opening chapters deal with the biochemical studies of the structure, mechanism, and differentiation of the voltage-sensitive sodium channel; and biochemical cycle of impedance variation in axonal membranes. The succeeding chapters examine the effect of various compounds on the phosphorylation of nerve proteins and the molecular aspects of the actions of cyclic nucleotides at synapses. These topics are followed by discussions of the acetylcholine and choline acetyltransferase, as well as the polymorphism of cholinesterase in vertebrates. The closing chapters are devoted to the physical factors determining gated flux from and into sealed membrane fragments. The book can provide useful information to biologists, students, and researchers.

Book Description
In The Wrong Place: Alien Marine Crustaceans - Distribution, Biology And Impacts provides a unique view into the remarkable story of how shrimps, crabs, and lobsters – and their many relatives – have been distributed around the world by human activity, and the profound implications of this global reorganization of biodiversity for marine conservation biology. Many crustaceans form the base of marine food chains, and are often prominent predators and competitors acting as ecological engineers in marine ecosystems. Commencing in the 1800s global commerce began to move hundreds – perhaps thousands – of species of marine crustaceans across oceans and between continents, both intentionally and unintentionally. This book tells the story of these invasions from Arctic waters to tropical shores, highlighting not only the importance and impact of all prominent crustacean invasions in the world's oceans, but also the commercial exploitation of invasive crabs and shrimps. Topics explored for the first time in one volume include the historical roots of man's impact on crustacean biogeography, the global dispersal of crabs, barnacle invasions, insights into the potential scale of tropical invasions, the history of the world's most widely cultured shrimp, the invasive history and management of red king crabs in Norway, Chinese mitten crabs in England, and American blue crabs in Europe, the evolutionary ecology of green crabs, and many other subjects as well, touching upon all ocean shores.

Book Description
The world's nearly 7,000 species of crabs are immediately recognizable by their claws, sideways movement, stalked eyes, and thick outer shells. These common crustaceans are found internationally, thriving in various habitats from the edge of the sea to the depths of the ocean, in fresh water or on land. Despite having the same basic body type as decapod crustaceans-true crabs have heavy exoskeletons and ten limbs with front pincer claws-crabs come in an enormous variety of shapes and sizes, from the near microscopic to the giant Japanese spider crab. In Walking Sideways, Judith S. Weis provides an engaging and informative tour of the remarkable world of crabs, highlighting their unique biology and natural history. She introduces us to recently discovered crabs such as the Yeti crab found in deep sea vents, explains what scientists are learning about blue and hermit crabs commonly found at the shore, and gives us insight into the lifecycles of the king and Dungeness crabs typically seen only on dinner plates. Among the topics Weis covers are the evolution and classification of crabs, their habitats, unique adaptations to water and land, reproduction and development, behavior, ecology, and threats, including up-to-date research. Crabs are of special interest to biologists for their communication behaviors, sexual dimorphism, and use of chemical stimuli and touch receptors, and Weis explains the importance of new scientific discoveries. In addition to the traditional ten-legged crabs, the book also treats those that appear eight-legged, including hermit crabs, king crabs, and sand crabs. Sidebars address topics of special interest, such as the relationship of lobsters to crabs and medical uses of compounds derived from horseshoe crabs (which aren't really crabs). While Weis emphasizes conservation and the threats that crabs face, she also addresses the use of crabs as food (detailing how crabs are caught and cooked) and their commercial value from fisheries and aquaculture. She highlights other interactions between crabs and people, including keeping hermit crabs as pets or studying marine species in the laboratory and field. Reminding us of characters such as The Little Mermaid's Sebastian and Sherman Lagoon's Hawthorne, she also surveys the role of crabs in literature (for both children and adults), film, and television, as well in mythology and astrology. With illustrations that offer delightful visual evidence of crab diversity and their unique behaviors, Walking Sideways will appeal to anyone who has encountered these fascinating animals on the beach, at an aquarium, or in the kitchen.

Book Description
Many previous studies and books have been dedicated to fundamental and developmental aspects of biomarkers. The purpose of this book is to provide, through various case studies, an overview of the practical use of biological markers in marine animals to evaluate the health effects of environmental contamination in marine ecosystems. More precisely, the book presents the results obtained during the development and application of biological markers as indicators of exposure/effect to toxic chemicals in marine environments, using diverse sentinel species such as fish, bivalves and crustaceans. An important aspect is also the publication of technical annexes that describe in detail the experimental procedures developed for both chemical and biochemical measurement.

Book Description
About 90 per cent of the 10,000 known species of the Crustacea Decapoda live in oceans and adjacent coastal and estuarine regions, and most of them pass through a complex life history comprising a benthic (juvenile-adult) and a planktonic (larval) phase. The larvae show a wide array of adaptations to the pelagic environment, including modifications in their functional morphology, anatomy, the molting cycle, nutrition, growth, chemical composition, metabolism, energy partitioning, ecology and behaviour.;All these traits are reviewed in this volume, attempting to promote an integrated, multidisciplinary view of the biology of larval Decapoda and other crustacean taxa. Emphasis is placed on the lesser-known anatomical, bioenergetic and ecophysiological aspects of larval life, as morphology has already been extensively documented. Changes in biological parameters (for example, rates of feeding, growth, metabolism) are shown in successive developmental stages, within individual stages, and as responses to environmental factors. Particular attention is paid to interrelationships between intrinsic phenomena (molting cycle, organogenesis, growth) and the overlaying effects of extrinsic factors (for example, food, temperature, salinity, pollution). Concluding from the available data, major bias and gaps in present knowledge of larval biology are identified and discussed as to their potential significance in future research.

Book Description
There has been a continual expansion in aquaculture, such that total production is fast approaching that of wild-caught fisheries. Yet the expansion is marred by continued problems of disease. New pathogens emerge, and others become associated with new conditions. Some of these pathogens become well established, and develop into major killers of aquatic species. Diagnosis and Control of Diseases of Fish and Shellfish focuses on the diagnosis and control of diseases of fish and shellfish, notably those affecting aquaculture. Divided into 12 chapters, the book discusses the range of bacterial, viral and parasitic pathogens, their trends, emerging problems, and the relative significance to aquaculture. Developments in diagnostics and disease management, including the widespread use of serological and molecular methods, are presented. Application/dose and mode of action of prebiotics, probiotics and medicinal plant products used to control disease are examined, as well as the management and hygiene precautions that can be taken to prevent/control the spread of disease. This book will be a valuable resource for researchers, students, diagnosticians, veterinarians, fish pathologists and microbiologists concerned with the management of diseases of fish and shellfish.
