Parasitic flatworms include Cestodes (tapeworms) and trematodes (flukes, schistosomes, etc), and are the cause of a number of major diseases of medical and veterinary significance. Much recent research has focused on molecular biology and genomics. this book aims to review advances in our understanding of these and related topics such as flatworm biochemistry, immunology and physiology. Where appropriate, comparisons are made between different parasitic flatworms and between parasitic and free-living species. Contributors to the book include leading authorities from Europe, North and South America, and Australia.

A practical guide to the management of habitat for invertebrates. Many invertebrates are highly specialised creatures with very precise habitat requirements. This means that they can be very sensitive indicators of environmental change. It also means that they can be lost from a site through small changes in management of their habitat. This book is a practical manual covering management for invertebrates: it provides guidelines to enable reserve managers and conservationists to take account of the vulnerable habitat features so important to invertebrates. The introduction gives an overview of British invertebrate species, site size and vegetation structure, management need of invertebrates and a summary of invertebrate survey methods. The author then deals, chapter-by-chapter, with each major habitat type: woodland, grasslands, lowland heaths, freshwater wetlands, and coastlands. This is a digital reprint of the 2001 edition (ISBN:0-901930-30-0) - there are no changes or updates from the 2001 edition.

More than seventy percent of the earth's surface is covered by ocean - the home to a staggering and sometimes overwhelming diversity of organisms, a majority of which reside in pelagic form. Marine invertebrate larvae are an integral part of this pelagic diversity and have stimulated the curiosity of researchers for centuries. This book will provide an important, modern update on the topic of larval ecology, representing the first major synthesis of this interdisciplinary field for more than 20 years. The content will be structured around four major areas: evolutionary origins and transitions in developmental mode; functional morphology and ecology of larval forms; larval transport, settlement, and metamorphosis; climate change and larval ecology at the extremes. This novel synthesis will integrate traditional larval ecology with life history theory, evolutionary developmental biology, and modern genomics research.

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 authoritative guide enables accurate identification of the common components of the inshore benthic invertebrates of the British Isles and adjacent European coasts, as well as a substantial proportion of fish species. This new edition builds upon the strengths of the earlier work and is thoroughly revised throughout to incorporate advances in both the taxonomy and ecology of the organisms concerned.

Invertebrates perform such vital roles in global ecosystems and so strongly influence human wellbeing that biologist E.O. Wilson was prompted to describe them as little things that run the world. As they are such powerful shapers of the world around us, their response to global climate change is also pivotal in meeting myriad challenges looming on the horizon everything from food security and biodiversity to human disease control. This book presents a comprehensive overview of the latest scientific knowledge and contemporary theory relating to global climate change and terrestrial invertebrates. Featuring contributions from top international experts, this book explores how changes to invertebrate populations will affect human decision making processes across a number of crucial issues, including agriculture, disease control, conservation planning, and resource allocation. Topics covered include methodologies and approaches to predict invertebrate responses, outcomes for disease vectors and ecosystem service providers, underlying mechanisms for community level responses to global climate change, evolutionary consequences and likely effects on interactions among organisms, and many more. Timely and thought-provoking, Global Climate Change and Terrestrial Invertebrates offers illuminating insights into the profound influence the simplest of organisms may have on the very future of our fragile world.

In this study of arthropod predador-prey systems Michael Hassell shows how many of the components of predation may be simply modeled in order to reveal their effects on the overall dynamics of the interacting populations. Arthropods, particularly insects, make ideal subjects for such a study because their generation times are characteristically short and many have relatively discrete generations, inviting the use of difference equation models to describe population changes. Using analytical models framed in difference equations, Dr. Hassell is able to show how the detailed biological processes of insect predator-prey (including host-parasitoid) interactions may be understood.

Emphasizing the development and subsequent stability analysis of general models, the author considers in detail several crucial components of predator-prey models: the prey's rate of increase as a function of density, non-random search, mutual interference, and the predator's rate of increase as a function of predator survival and fecundity. Drawing on the correspondence between the models and field and laboratory data, Dr. Hassell then discusses the practical implications for biological pest control and suggests how such models may help to formulate a theoretical basis for biological control practices.

Toxocara is a parasitic helminth worm which continues to stimulate both public concern and scientific interest. "Toxocara canis" and "T.cati," the most studied species, are gastrointestinal parasites of dogs and cats and their eggs can contaminate the environment, thus exposing humans and other mammals and birds to infection. Many questions remain unanswered about the host-parasite relationship, its epidemiology and public health significance. Veterinarians and clinicians are interested in its importance as a zoonosis. The parasite's capacity to cause ocular disease is of concern to ophthalmologists, while its propensity to stimulate allergic manifestations is of interest to allergologists, dermatologists and respiratory medicine specialists. Furthermore "Toxocara" provides a unique model system to explore questions in parasite biology. This book provides a comprehensive review of Toxocara and the disease it causes known as toxocariasis.

Invertebrates have proven to be extremely useful model systems for gaining insights into the neural and molecular mechanisms of sensory processing, motor control and higher functions such as feeding behavior, learning and memory, navigation, and social behavior. A major factor in their enormous contributions to neuroscience is the relative simplicity of invertebrate nervous systems. In addition, some invertebrates, primarily the molluscs, have large cells, which allow analyses to take place at the level of individually identified neurons. Individual neurons can be surgically removed and assayed for expression of membrane channels, levels of second messengers, protein phosphorylation, and RNA and protein synthesis. Moreover, peptides and nucleotides can be injected into individual neurons. Other invertebrate model systems such as Drosophila and Caenorhabditis elegans offer tremendous advantages for obtaining insights into the neuronal bases of behavior through the application of genetic approaches. The Oxford Handbook of Invertebrate Neurobiology reviews the many neurobiological principles that have emerged from invertebrate analyses, such as motor pattern generation, mechanisms of synaptic transmission, and learning and memory. It also covers general features of the neurobiology of invertebrate circadian rhythms, development, and regeneration and reproduction. Some neurobiological phenomena are species-specific and diverse, especially in the domain of the neuronal control of locomotion and camouflage. Thus, separate chapters are provided on the control of swimming in annelids, crustaea and molluscs, locomotion in hexapods, and camouflage in cephalopods. Unique features of the handbook include chapters that review social behavior and intentionality in invertebrates. A chapter is devoted to summarizing past contributions of invertebrates to the understanding of nervous systems and identifying areas for future studies that will continue to advance that understanding.

Dieses Buch entstand aus der Begeisterung fur die Vielfalt der Bodenarthropoden und aus der Sorge um einen bedrohten Lebensraum, dem wir mehr Beachtung schenken sollten, als ihn nur "mit Fussen zu treten".

Planarians, a class of flatworm, are extraordinary: they possess the remarkable ability to regenerate lost body parts, including complete regeneration of the nervous system. If cut into pieces, each piece of the planarian can regenerate into a complete organism. They are also unique among invertebrates in that they display addiction-like behaviors to many drugs abused by humans. Because of these distinct neurological traits, the planarian is often used as an animal model in neurological research, being used most recently for developments in neuropharmacology. The First Brain is a discussion of how planarians have been used in neuropharmacology, and what role they have played in scientific developments that have a high impact on our culture. Planarians have been the animal models for research in drug addiction, antidepressant development, and various other topics in biology, neurobiology, and even zoology. Pagan uses these flatworms as a framework to explore the history of biological research. The book provides accessible background information on how biomedical research is impacted by evolution, and defines neurobiology and neuropharmacology in ways that are easy to understand. At the same time, Pagan provides enough detail for the book to useful for scientists working in various subsections of biology. The planarian has played a key role in the history biological, neuropharmacological, and zoological research, and has even made appearances in a few unexpected places in popular culture. One Pagan explores all these roles, and shows us why the planarian truly is one of the most extraordinary and influential organisms in scientific research today.

Acanthocephalans, or spiny-headed worms, are endoparasites found in almost all marine, freshwater and terrestrial systems. They infect a huge range of definitive and intermediate hosts during their life cycles, including both vertebrates and arthropods. This volume, first published in 2006, examines the distribution and abundance of the Acanthocephala, and uses this ecological information to reveal the group's enormous survival success. It discusses how the acanthocephalans have evolved differently to all other groups of parasites, and represent a distinct and alternative pathway of parasite evolution and host parasite-interactions. Written for graduate students and researchers in parasitology, ecology and zoology or anyone interested in reading about parasite ecology and evolution.

So much has to be crammed into today's biology courses that basic information on animal groups and their evolutionary origins is often left out. This is particularly true for the invertebrates. The second edition of Janet Moore's An Introduction to the Invertebrates fills this gap by providing a short updated guide to the invertebrate phyla, looking at their diverse forms, functions and evolutionary relationships. This book first introduces evolution and modern methods of tracing it, then considers the distinctive body plan of each invertebrate phylum showing what has evolved, how the animals live, and how they develop. Boxes introduce physiological mechanisms and development. The final chapter explains uses of molecular evidence and presents an up-to-date view of evolutionary history, giving a more certain definition of the relationships between invertebrates. This user-friendly and well-illustrated introduction will be invaluable for all those studying invertebrates.

Invertebrate Conservation and Agricultural Ecosystems explores the diverse interests of invertebrate conservation and agricultural production. It is both an introduction to invertebrate conservation biology for agriculturists and an introduction to crop protection for conservation biologists, demonstrating how these two disparate fields may draw on each other for greater collective benefit. It draws on recent literature to show how invertebrate conservation in highly altered landscapes may be promoted and enhanced. The book deals with problems of, and approaches to, invertebrate conservation in highly managed agricultural ecosystems, and how biodiversity may be promoted without compromising agricultural production. It draws attention to the importance of invertebrates in agricultural systems and their role in ecosystem functions.

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 in to 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.
