In this volume outstanding specialists review the state of the art in nervous system research for all main invertebrate groups. They provide a comprehensive up-to-date analysis important for everyone working on neuronal aspects of single groups, as well as taking into account the phylogenesis of invertebrates. The articles report on recently gained knowledge about diversification in the invertebrate nervous systems, and demonstrate the analytical power of a comparative approach. Novel techniques in molecular and developmental biology are creating new perspectives that point toward a theoretical foundation for a modern organismic biology. The comparative approach, as documented here, will engage the interest of anyone challenged by the problem of structural diversification in biology.

The more we learn about bees, the more extraordinary they seem. They have five eyes and beat their wings at almost 200 cycles per second. And to communicate with each other bees do make sounds but also dance. This book, packed with over 30 figures, gives a fascinating insight into the extraordinary complex and highly organised world of bees. The author, K. Weiss, explains the critical role that bees and bee-keeping play for human society, and offers advice for those interested in raising bees.

Many invertebrates are serious pests of agriculture (e.g., mites and locusts), vectors of disease (e.g., mosquitoes and aquatic snails) and venomous (e.g., scorpions), whilst others are beneficial to humans as pollinators, food sources, and detritivores. Despite their obvious ecological, medical, and economic importance, this is the first comprehensive review of invertebrate diseases to be available within a single volume. Concurrent molecular and bioinformatics developments over the last decade have catalysed a renaissance in invertebrate pathology. High-throughput sequencing, handheld diagnostic kits, and the move to new technologies have rapidly increased our understanding of invertebrate diseases, generating a large volume of fundamental and applied research on the topic. An overview is now timely and this authoritative work assembles an international team of the leading specialists in the field to review the main diseases and pathologic manifestations of all the major invertebrate groups. Each chapter adopts a common plan in terms of its scope and approach to achieve a succinct and coherent synthesis. Invertebrate Pathology is aimed at graduate students and researchers in the fields of disease ecology, invertebrate biology, comparative immunology, aquaculture, fisheries, veterinary science, evolution, and conservation. It will be particularly useful for readers new to the field as well as a broader interdisciplinary audience of practitioners and resource managers.

Although of high abundance, diversity and ecological importance, meiofauna is little covered by relevant scientific media. How can this negligence be overcome? The present treatise highlights promising meiofauna research fields, selected both from basic and applied science, as well as new methods that could strengthen the potential of meiobenthology. Selected recent meiofauna studies, often supported by rapidly advancing gene-based methods, underline the relevance and potential of meiobenthology revealing characteristics and harassments of ecosystems, not the least in extreme habitats. Also in the more classical domains such as taxonomy and phylogeny, progress in meiobenthos research defines a new and deeper scientific understanding.

Since 1972, scientists from all over the world working on fundamental questions of echinoderm biology and palaeontology have conferred every three years to exchange current views and results. The 11th International Echinoderm Conference held at the University of Munich, Germany, from 6-10 October 2003, continued this tradition. This volume comprises 95 submitted papers and 96 abstracts covering a wide spectrum from innovative student contributions to the lessons learnt from experienced specialists. The content of the contributions ranges from original research results to the latest synopses concerning a variety of topics, including visual sensing, larval cloning, mutable collagenous tissues, sea urchin aqua-culture, deuterostome phylogeny, palaeobiology and taphonomy.

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.

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.

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.

Dieser Atlas lenkt mit seinen zahlreichen rasterelektronischen Abbildungen den Blick auf die bizarre Welt der Wasserinsekten.

Daneben sind viele Arten von anderen Kontinenten und aus den verschiedensten aquatischen Lebensraumen der Welt berucksichtigt. Die erlauternden Texte und die klarenden Zeichnungen beschreiben die Biologie der dargestellten Wasserinsekten und zeigen, dass hinter der Formenmannigfaltigkeit der Tiere stets physiologische Mechanismen fur die oekologische Anpassung an das Leben im Wasser stehen.

Dieser Atlas bietet einen exemplarischen Einblick in das bizarre Reich der bodenbewohnenden Arthropoden. In der vergleichenden Darstellung von brillanten rasterelektronenmikroskopischen Abbildungen mit aussergewoehnlich lebensnahen Zeichnungen wird offenbar, dass hinter der Formenmannigfaltigkeit dieser Tiere physiologische Mechanismen fur oekologische Anpassungen an das differenzierte Leben im Boden stehen. Die Bedeutung der Arthropoden als Konsumenten am Abbau des pflanzlichen Bestandsabfalls und am Stoffkreislauf im Boden wird besonders hervorgehoben. 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".

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.

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.

Most undergraduate texts in invertebrate zoology (of which there are many) fall into one of two categories. They either offer a systematic treatment of groups of animals phylum by phylum, or adopt a functional approach to the various anatomical and physiological systems of the better known species. The Invertebrates is the first and only textbook to integrate both approaches, describing the range and diversity of invertebrates and the way they work, thus meeting the modern teaching needs of the subject.

This new edition has been completely revised and updated. The molecular systematics sections have been rewritten and the book now has a strong evolutionary theme throughout, which reflects the importance of molecular techniques.

The first part of the book describes all the known phyla of invertebrates with living representatives, together with their component classes. Rather than outline all the anatomical features of different types of animals, the book distills those essential characteristics of each group with which the student should be familiar. Lists of diagnostic features permit comparison between the phyla; the diversity of body plans illustrated by line figures of different forms.

The second part concentrates on the unifying features of invertebrate functional anatomy, physiology and behavior, describing how the invertebrates display a range of solutions to the problems of living and reproduction. Throughout, form and function are presented from an evolutionary viewpoint, in the light of the selective pressures that have influenced and continue to mold invertebrates biology.

Paleozoology and Paleoenvironments outlines the reconstruction of ancient climates, floras, and habitats on the basis of animal fossil remains recovered from archaeological and paleontological sites. In addition to outlining the ecological fundamentals and analytical assumptions attending such analyzes, J. Tyler Faith and R. Lee Lyman describe and critically evaluate many of the varied analytical techniques that have been applied to paleozoological remains for the purpose of paleoenvironmental reconstruction. These techniques range from analyses based on the presence or abundance of species in a fossil assemblage to those based on taxon-free ecological characterizations. All techniques are illustrated using faunal data from archaeological or paleontological contexts. Aimed at students and professionals, this volume will serve as fundamental resource for courses in zooarchaeology, paleontology, and paleoecology.

The book 'Silent Spring' written by Rachel Carson in 1962, is considered the la- mark in changing the attitude of the scientists and the general public regarding the complete reliance on the synthetic pesticides for controlling the ravages caused by the pests in agriculture crops. For about ve decades, the Integrated Pest Mana- ment (IPM) is the accepted strategy for managing crop pests. IPM was practiced in Canet ~ e Valley, Peru in 1950s, even before the term IPM was coined. Integrated Pest management: Innovation-Development Process, Volume 1, focuses on the recog- tion of the dysfunctional consequences of the pesticide use in agriculture, through researchanddevelopmentoftheIntegratedPest Managementinnovations. Thebook aims to update the information on the global scenario of IPM with respect to the use of pesticides, its dysfunctional consequences, and the concepts and advan- ments made in IPM systems. This book is intended as a text as well as reference material for use in teaching the advancements made in IPM. The book provides an interdisciplinary perspective of IPM by the forty-three experts from the eld of entomology, plant pathology, plant breeding, plant physiology, biochemistry, and extension education. The introductory chapter (Chapter 1) gives an overview of IPM initiatives in the developed and developing countries from Asia, Africa, Australia, Europe, Latin America and North America. IPM concepts, opportunities and challenges are d- cussed in Chapter 2.
