Book Description
Animal Energetics, Volume 2: Bivalvia through Reptilia is part of a two-volume treatise focusing on the integrated picture of the energy transformation process at the organismic level. Since it is almost impossible to restrict meaningful discussions to only one level of organization, some reference is made to population energetics as well as to the suborganismic level. The bioenergetics of both vertebrate and invertebrate groups are discussed. Specifically, the bioenergetics of bivalves, gastropods, bryozoans, pogonophorans, echinoderms, lower chordates, fishes, amphibians, and reptiles are covered. Understanding the efficient and fast transformation of biological energy has become an important issue in world affairs; studies on energetics and growth of thermoconformers can therefore be expected to expand greatly in the future. This book aims to provide many keys to a broader understanding of biology as well as open untrodden avenues to biologists with the quest for newer energy sources and efficient methods of energy utilization.

Book Description
This book represents the first attempt to quantify environmental factors and life history traits that accelerate or decelerate species diversity in animals. About 15%, 8% and 77% of species are distributed in marine (70% of earth’s surface), freshwater (terra firma fosters more diversity. The harsh hadal, desert and elevated montane habitats restrict diversity to 0.5-4.2%. Costing more time and energy, osmotrophic and suspension modes of food acquisition limit diversity to Selfing hermaphrodites (0.9%), parthenogens ( Incidence of heterogamety is four-times more in males than in females. Hence, evolution is more a male-driven process. Egg size is determined by environmental factors, but lecithality is genetically fixed. In poikilotherms, sex is also determined by gene(s), but differentiation by environmental factors. The extra-ovarian vitellogenesis (> 96%), spermatozoan (81%) rather than spermatophore mechanism of sperm transfer, promiscuity and polygamy over monogamy, iteroparity (99.6%) over semelparity and internal fertilization (84%) are preferred, as they accelerate diversity. Body size and egg size determine fecundity. Indirect life cycle (82%) and incorporation of feeding larval stages accelerate diversity. Brooding and viviparity (6.4%) decelerate it. Parasitism extends life span and liberates fecundity from eutelism. Evolution is an ongoing process, and speciation and extinction are its unavoidable by-products. The in-built conservation mechanism of reviving life after a sleeping duration has been reduced from a few million years in microbial spores to a few thousand years in plant seeds and a few hundred years in dormant eggs in animals. Hence, animal conservation requires priority. The existence of temperature-resistant/insensitive individuals, strains and species shall flourish during the ongoing global warming and earth shall continue with such burgeoning species, hopefully inclusive of man.

Book Description
Exploring the potential use of bivalves as indicators and monitors of ecosystem health, this book describes live and computer simulated experiments, mesocosm studies, and field manipulation experiments. This second edition discusses major new developments, including phase shifts in many coastal and estuarine ecosystems dominated by suspension-feeding bivalves, the invasion or introduction of alien bivalve species, the rapid growth of environmental restoration focused on bivalves, and the examination of geological history with regard to global climate change and its impact on bivalve-dominated systems.

Book Description
Marine Bivalve Molluscs Marine Bivalve Molluscs is a comprehensive and thoroughly updated Second Edition of Bivalve Molluscs, covering all major aspects of this important class of invertebrates. As well as being an important class biologically and ecologically, many of the bivalves are fished and cultured commercially (e.g. mussels, oysters, scallops and clams) in a multi-billion dollar worldwide industry. Elizabeth Gosling has written a landmark book that will stand for many years as the standard work on the subject. Chapters in Marine Bivalve Molluscs cover morphology, ecology, feeding, reproduction, settlement and recruitment, growth, physiology, fisheries, aquaculture, genetics, diseases and parasites, and public health issues. A full understanding of many of these aspects is vital for all those working in bivalve fisheries and culture. An essential purchase for anyone concerned with this important class of animals, copies of Marine Bivalve Molluscs should be on the shelves of biologists, ecologists, environmental scientists, fisheries scientists and personnel within the aquaculture industry. Copies of the book should be available in all libraries and research establishments where these subjects are studied or taught. REVIEWS OF THE FIRST EDITION An admirable achievement…a valuable addition to marine sciences libraries everywhere. The back cover of this book says that it is a landmark text that will stand for many years as the standard work on this subject. I can only agree with this sentiment. ~ Aquaculture A welcome addition to the literature and provides the reader with a comprehensive overview of biological and environmental factors that affect and control both natural populations of marine bivalves and culture operations. ~ Aquaculture International The author has done an admirable job in compiling a wealth of information into a readable text. ~ Transactions of the American Fisheries Society Will serve well as a description of much of both the experimental biology and the aquaculture of bivalves. ~ Journal of Experimental Marine Biology and Ecology Provides excellent reviews of all major aspects…an extremely important reference for anyone engaged in bivalve research, fisheries management, and aquaculture. ~ Quarterly Review of Biology The book is very readable, in an easy style. It is well illustrated and there is a wealth of data and statistics presented. ~ Bulletin of the Malacological Society of London

Book Description
Bivalves are key components of recent marine and freshwater ecosystems and have been so for most of the Phanerozoic. Their rich and long fossil record, combined with their abundance and diversity in modern seas, has made bivalves the ideal subject of palaeobiological and evolutionary studies. Despite this, however, topics such as the early evolution of the class, relationships between various taxa and the life habits of some key extinct forms have remained remarkably unclear. This volume integrates palaeontological and zoological approaches and sheds new light on the course of bivalve evolution.

Book Description
Scallops are among the better known shellfish and are widely distributed throughout the world. They are of great economic importance, support both commercial fisheries and mariculture efforts and occupy a unique niche in the marine environment. Contributions from world leaders in scallop research and culture cover all facets of scallop biology including anatomy, taxonomy, physiology, ecology, larval biology and neurobiology. Chapters are also devoted to diseases and parasites, genetics, population dynamics and the adductor muscle, with extensive reference lists provided for each chapter. Since the publication of the first edition of Scallops: Biology, Ecology and Aquaculture in 1991, commercial interest in scallops has grown globally and this is reflected in the seventeen extensive chapters covering both fisheries and aquaculture for all species of scallops in all countries where they are fished or cultured. The Second Edition is the only comprehensive treatise on the biology of scallops and is the definitive reference source for advanced undergraduate and graduate students, mariculturists, managers and researchers. It is a valuable reference for anyone interested in staying abreast of the latest advances in scallops. * Offers over 30 detailed chapters on the developments and ecology of scallops* Provides chapters on various cultures of scallops in China, Japan, Scandinivia, Eastern North American, Europe, and Eastern North America* Includes details of their reproduction, nervous system and behavior, genetics, disease and parasites, and much more* Complete updated version of the first edition
