Wetlands are crucial ecosystems that help filter a great number of toxicants out of the earth's waters. They must be managed and occasionally even built from scratch, including all of the flora and fauna that grows there. Invertebrates play a key role in the wetland food chain. This comprehensive resource is the first dedicated solely to the ecology and management of invertebrates.

As the world's population and the demand for seafood increase, the production of seafood from aquaculture has also seen massive increase and is set to continue. With wild stocks of many molluscan species depleted, aquaculture is firmly recognised as the means now, and for the future, of bridging the gap between the supply and demand of seafood.

This important book covers the general biology of bivalves, hatchery culture methods and specific and comprehensive details of the cultivation of many commercially important species, including clams, oysters, mussels, scallops and abalone.

Based on the author's extensive experience and hands on research into this subject, Molluscan Shellfish Farming provides essential information for all involved in the culture of molluscs. The book will be particularly useful for aquaculture personnel on working fish farms and in academic research posts. Libraries in all universities and research establishments where aquaculture and biological sciences are studied and taught should have copies of this book available.

Part of this book is based on a Buckland Lecture, sponsored by the Buckland Trustees

About 95 per cent of all known animal species are invertebrates. A knowledge of their sexual, reproductive, and developmental biology is essential for the effective management of species that are economically useful to man or are harmful to him, his crops, and livestock. This treatise is the first to cover all aspects of reproduction and development of the entire spectrum of invertebratesterrestrial, marine, freshwater, brackish-water, free-living, and parasitic. The chapters, by leading world experts in their fields, are up-to-date and informative, and suggest a number of problems for future research.

Teeming with weird and wonderful life--giant clams and mussels, tubeworms, "eyeless" shrimp, and bacteria that survive on sulfur--deep-sea hot-water springs are found along rifts where sea-floor spreading occurs. The theory of plate tectonics predicted the existence of these hydrothermal vents, but they were discovered only in 1977. Since then the sites have attracted teams of scientists seeking to understand how life can thrive in what would seem to be intolerable or extreme conditions of temperature and fluid chemistry. Some suspect that these vents even hold the key to understanding the very origins of life. Here a leading expert provides the first authoritative and comprehensive account of this research in a book intended for students, professionals, and general readers. Cindy Lee Van Dover, an ecologist, brings nearly two decades of experience and a lively writing style to the text, which is further enhanced by two hundred illustrations, including photographs of vent communities taken in situ.

The book begins by explaining what is known about hydrothermal systems in terms of their deep-sea environment and their geological and chemical makeup. The coverage of microbial ecology includes a chapter on symbiosis. Symbiotic relationships are further developed in a section on physiological ecology, which includes discussions of adaptations to sulfide, thermal tolerances, and sensory adaptations. Separate chapters are devoted to trophic relationships and reproductive ecology. A chapter on community dynamics reveals what has been learned about the ways in which vent communities become established and why they persist, while a chapter on evolution and biogeography examines patterns of species diversity and evolutionary relationships within chemosynthetic ecosystems.

Cognate communities such as seeps and whale skeletons come under scrutiny for their ability to support microbial and invertebrate communities that are ecologically and evolutionarily related to hydrothermal faunas. The book concludes by exploring the possibility that life originated at hydrothermal vents, a hypothesis that has had tremendous impact on our ideas about the potential for life on other planets or planetary bodies in our solar system.

The marine zooplankton is one of the most fascinating and diverse assemblages of animals known to biologists. This student manual provides a photographic guide to representative forms of the major groups from medusae and comb jellies to larval fish and squid. In it, only photographs of live and active organisms appear, giving a unique visual perspective. In this new edition, the authors have revised and updated the taxonomy and morphology so that combined with information on behavior and development, this book creates a vivid and essential reference.

This volume is a republication in one volume of the 10-part "CIH Keys to the Nematode Parasites of Vertebrates," first published between 1974 and 1983. For many years the "Keys" have provided a working tool to those within the field and laboratory needing to know "what is this worm?"Now due to popular demand and to coincide with the long awaited publication of the supplement volume, the "Keys" will be presented as one volume, refreshed and reformatted with the additional convenience of reordering into superfamily. As an indispensable guide the "Keys" shall continue to be an essential resource to those working within medical, veterinary and biological departments worldwide for many more years to come.

The Aphelenchida, Longidoridae and Trichodoridae are groups of nematodes that include almost 1,000 species from some forty genera. A number are of known agricultural importance, both in their own right as parasites of fungi or higher plants and/or as vectors of certain plant viruses. While monographs exist on the systematics and taxonomy of a number of nematode groups, no recent volume covers the three groups included here. This book aims to provide a practical, working guide to the taxa of the Aphelenchida, Longidoridae and Trichodoridae, in such a form as to facilitate usage by both specialist taxonomists and general nematologists. Keys to generic level are included, each genus being diagnosed, illustrated and provided with a comprehensive list of nominal species and, where appropriate, synonyms. General notes on the bionomics and distribution are appended and some 22 species, mostly those of economic importance, are individually described in greater detail. In addition, a general introduction to each of the three systematic sections includes an historical review, basic morphology and a summary of the bionomics. With a comprehensive bibliography, the book is a unique guide to these groups of plant parasitic and free-living nematodes.

The Butterflies of Britain & Ireland provides comprehensive coverage of all our resident and migratory butterflies, including the latest information on newly discovered species such as Cryptic Wood White and the Geranium Bronze. When first published in 1991 it won the Natural World Book of the Year Award and won plaudits from all quarters. Fully revised, considerably expanded and reset in 2010, it was judged that year's Guardian Nature Book of the Year. Now revised again to reflect the latest research findings, and with up-to-date distribution maps, this remarkable book is THE guide to the appearance, behaviour, life cycle and ecology of the butterflies of Britain and Ireland.

In "The Descent of Man, " Charles Darwin proposed that an ant's brain, no larger than a pin's head, must be sophisticated to accomplish all that it does. Yet today many people still find it surprising that insects and other arthropods show behaviors that are much more complex than innate reflexes. They are products of versatile brains which, in a sense, think.

Fascinating in their own right, arthropods provide fundamental insights into how brains process and organize sensory information to produce learning, strategizing, cooperation, and sociality. Nicholas Strausfeld elucidates the evolution of this knowledge, beginning with nineteenth-century debates about how similar arthropod brains were to vertebrate brains. This exchange, he shows, had a profound and far-reaching impact on attitudes toward evolution and animal origins. Many renowned scientists, including Sigmund Freud, cut their professional teeth studying arthropod nervous systems. The greatest neuroanatomist of them all, Santiago Ramon y Cajal-founder of the neuron doctrine-was awed by similarities between insect and mammalian brains.

Writing in a style that will appeal to a broad readership, Strausfeld weaves anatomical observations with evidence from molecular biology, neuroethology, cladistics, and the fossil record to explore the neurobiology of the largest phylum on earth-and one that is crucial to the well-being of our planet. Highly informative and richly illustrated, "Arthropod Brains" offers an original synthesis drawing on many fields, and a comprehensive reference that will serve biologists for years to come.

This book, in three volumes, presents a detailed revision of the systematics and taxonomy of the platyhelminth class "Trematoda," subclasses "Aspidogastrea" and "Digenea," with keys for the identification of these parasites at the superfamily, family, subfamily and generic levels.The trematodes are parasitic worms infecting all vertebrate groups and include families of significance to human and animal health, with considerable economic impact. Volume 1 covers the subclass "Aspidogastrea" and order "Strigeida," while the second and third volumes will cover the orders "Echinostomida" and "Plagiorchiida."

A thorough understanding of planktonic organisms is the first step towards a real appreciation of the diversity, biology, and ecological importance of marine life. A detailed knowledge of their distribution and community composition is particularly important since these organisms are often very delicate and sensitive to change, and can be used as early indicators of environmental change. Natural and man-induced modification of the environment can affect both the distribution and composition of plankton, with important ecological and economic impacts. Marine Plankton provides a practical guide to plankton biology with a large geographic coverage spanning the North Sea to the north-eastern Atlantic coast of the USA and Canada. The book is divided into three sections: an overview of plankton ecology, an assessment of methodology in plankton research covering sampling, preservation, and counting of samples, and a taxonomic guide richly illustrated with detailed line drawings to aid identification. This is an essential reference text suitable for senior undergraduate and graduate students taking courses in marine ecology (particularly useful for fieldwork) as well as for professional marine biologists. It will also be of relevance and use to environmental scientists, conservation biologists, marine resource managers, environmental consultants, and other specialised practitioners.

This 4th edition updates the latest research on earthworms. More than 3,000 species of earthworm exist in the world. They are considered to be an important ally in advancing environmental and biomedical research. Earthworms play an important role in forest or agricultural ecosystems and play an increasing role in biomedical issues. Earthworms are critical to the environment because they consume huge quantities of decomposed litter, manure, and other organic matter deposited on soil -- helping to convert it into rich topsoil Earthworms can also help reduce soil compaction, improve permeability--thus providing channels for root growth, water infiltration, and gas exchange. Earthworms are also important animals for the assessment of the toxicity of chemicals, such as herbicides and pesticides, which are deliberately released into the environment. Earthworms are superb barometers' or sentinels' providing an early warning of deterioration in soil quality.

Their story began 500 million years ago, but we only started to get to know them in 1746, when Linne described the first ostracod species. Vividly portraying the freshwater ostracods, this comprehensive reference work gathers the knowledge gained during some 250 years, but which to date has remained scattered throughout the literature. It starts with an introduction to the class Ostracoda with a special focus on freshwater ostracods and highlights practical methods in their study. The systematic part includes an introduction to all families; identification keys for all subfamilies, genera and species; diagnoses for each subfamily and genus; and lists of synonyms and distribution of species. The text is richly illustrated with distribution maps, line drawings of key generic characteristics, and numerous SEM photographs. Serving as an excellent starting point for all further research on freshwater ostracods, it can be widely used not only by ostracodologists, but also by crustaceologists, evolutionists and ecologists.

Our oceans are becoming increasingly inhospitable to life--growing toxicity and rising temperatures coupled with overfishing have led many marine species to the brink of collapse. And yet there is one creature that is thriving in this seasick environment: the beautiful, dangerous, and now incredibly numerous jellyfish. As foremost jellyfish expert Lisa-ann Gershwin describes in "Stung , "the jellyfish population bloom is highly indicative of the tragic state of the world's ocean waters, while also revealing the incredible tenacity of these remarkable creatures. Recent documentaries about swarms of giant jellyfish invading Japanese fishing grounds and summertime headlines about armadas of stinging jellyfish in the Mediterranean and Chesapeake are only the beginning--jellyfish are truly taking over the oceans. Despite their often dazzling appearance, jellyfish are simple creatures with simple needs: namely, fewer predators and competitors, warmer waters to encourage rapid growth, and more places for their larvae to settle and grow. In general, oceans that are less favorable to fish are more favorable to jellyfish, and these are the very conditions that we are creating through mechanized trawling, habitat degradation, coastal construction, pollution, and climate change. Despite their role as harbingers of marine destruction, jellyfish are truly enthralling creatures in their own right, and in "Stung ," Gershwin tells stories of jellyfish both attractive and deadly while illuminating many interesting and unusual facts about their behaviors and environmental adaptations. She takes readers back to the Proterozoic era, when jellyfish were the top predator in the marine ecosystem--at a time when there were no fish, no mammals, and no turtles; and she explores the role jellies have as middlemen of destruction, moving swiftly into vulnerable ecosystems. The story of the jellyfish, as Gershwin makes clear, is also the story of the world's oceans, and "Stung "provides a unique and urgent look at their inseparable histories--and future.
