It is the first book in the market solely dedicated to this important group of insects, and contains 15 chapters on natural history and ecology, morphology, taxonomy and phylogenetics, evolution and diversity, population dynamics, resistance, symbiotic associations, natural enemies, climate change, management strategies, economics, and politics, with some chapters exclusively devoted to some of the most economically important bark beetle genera, including Dendroctonus, Ips, Tomicus, Hypothenemus, and Scolytus. This text is ideal for entomology and forestry courses, and is aimed at scientists, faculty members, forest managers, practitioners of biological control of insect pests, mycologists interested in bark beetle-fungal associations, and students in the disciplines of entomology, ecology, and forestry.

Insects represent the most abundant and diverse animal group on Earth. The number of described species is more than one million and up to ten million are estimated. Insects have one of the widest distributions in the world because they have adapted to extreme ranges of environments.

Molecular ecology studies ecological processes based on the analysis of biomacromolecules, particularly DNA, RNA, and proteins, but also of low-molecular weight signal compounds. Molecular ecology uses the exciting opportunities offered by the tools of molecular biology.

The book presents current entomological research, where molecular tools help to advance traditional ecological studies. Chapters include ones on insect insect and insect plant interactions, on mechanisms of environmental adaptation, or on the use of insect biotechnology in pest and vector control. The book helps to combine powerful methods in molecular biology with exciting issues in ecology to understand why insects became "masters of survival.""

Containing proceedings of the VIIIth International Rotifer Symposium which was held in Collegeville, Minnesota, USA, on June 22-27 1997, this volume includes review papers and reports of recent research findings along with the presentation of new methods in rotifer biology. The publications contained in this volume reflect the wide diversity of approaches, methods of analysis and conclusions that characterize research on the Rotifera. Some of the topics addressed are: rotifer distribution, responses to biotic and abiotic factors, genetic profile of individuals and populations, rotifer feeding and mating behavior, morphology, phylogeny and taxonomy.

Understanding biotic stress and plant yield allows for the practical development of economic decision making, an instrumental part of Integrated Pest Management. And further, the impact of biotic injury on plant yield bears directly on the basic biological questions of population dynamics, life history strategies, community structure, plant-stressor coevolution, and ecosystem nutrient cycling. Biotic Stress and Yield Loss is a comprehensive review of the latest conclusions of yield loss in entomology, weed science, and plant pathology, combining state-of-the-art theory with successful applications.

This book is unique in that it is the first to cover all biotic stressors, insects, weeds, and plant pathogens, and their impact on plant yield and fitness. It focuses on current knowledge of yield and fitness loss in both natural and agricultural ecosystems and on a physiologically based approach to provide a common basis for considering and discussing biotic stress. By considering biotic stress within the context of plant ecophysiology, Biotic Stress and Yield Loss attempts to elevate knowledge of biotic stress to the same level as abiotic stress and makes an argument for integrating the two types of stress.

Recent Advances in Freshwater Crustacean Biodiversity and Conservation focuses on minor crustacean groups and regionally endemic groups, all from freshwaters. Chapters in this book cover crustaceans such as Maxillopods, Mysids, Cumaceans, Isopods, Amphipods, Branchiopods, Copepods, and Decapods. Each looks at global or regional fauna and discusses conservation issues for that group. The majority of the chapters are based on papers presented at symposia organized by the editors at two international scientific meetings held in Barcelona and Washington DC. The contributors are world-renowned experts on their groups, as well as on freshwater crustacean conservation and biodiversity at global levels. It has previously been difficult for conservation managers, NGOs, and university professors and students who may not have access to comprehensive journal subscriptions to find relevant information on diversity and conservation of freshwater crustaceans. This book meets that need, addressing crustacean groups not previously treated and providing additional information beyond any presented in existing books. As the editors write in their introduction: we cannot conserve and we cannot protect what we do not know exists. This is a reliable, cutting-edge reference for anybody involved in crustacean research: students, researchers, agencies, and NGOs, as well as science educators, conservationists, and government conservation policymakers. The book will also be useful for those working in aquaculture and fisheries, given that many of the taxa discussed are economically important.

Dragonflies and damselflies are some of the most beautiful, fragile and resilient insects found in the natural world.

Dragonflies and Damselflies of Britain and Western Europe features all 98 species found in the region. Packed with outstanding photography, this comprehensive book includes close-up illustrations to highlight key identification features, diagrams of wing venation, and detailed guides to dragonfly larvae and exuviae. Each species account includes an accurate distribution map and information on field characteristics, confusion species, habitat and ecology. An introduction to the life cycle of Odonata, guidance on when and where to look for them, and the best ways to observe and photograph dragonflies and damselflies in the field are also included. These sections, combined with the identification guides, make this book the ultimate resource for any field naturalist or entomologist interested in these incredible insects.

This book overviews the role of insects in providing various human, environmental, recreational, aesthetic, and cultural services. It presents a comprehensive account of insect service providers to show different aspects of insects and cultivate the appreciation of insects. Insects are beneficial to humans as ecofriendly tools, as parasitoids and predators in the biological control of insect pests and vectors, reducing the use of agrochemicals in modern agriculture and protecting the environment. Insects facilitate crop pollination and increase the agricultural yield. They are farmers' friends, and serve as food for the human population worldwide, provide pharmaceuticals, take part in ecosystem services, and work as scavengers. Insects are used in disease therapy and wound healing. They are also helpful in criminal investigations and are the best models for research and technology innovations. Insects also yield various silks, lac, honey, propolis, wax, etc., promoting insect tourism, recreations, and culture. This contributed volume focuses on these different beneficial aspects of insects in human life. This book will be of interest to undergraduate and postgraduate students of entomology, agricultural zoology, researchers, and anyone interested in insects, including policy planners.

Insects conquered the Earth long before we did and will remain here long after we’re gone.

They outnumber us in the billions and are essential to many of the natural processes that keep us alive and that we take for granted. Yet, despite this, very few of us know much about the hidden world of insects.

In this fascinating new book, entomologist and broadcaster George McGavin takes a deep dive to reveal the unknown truths about the most successful and enduring animal group the world has ever seen, and to show the unseen effects this vast population has on our planet, if only we care to look.

McGavin explores not only the incredible traits that insects have evolved to possess, such as dragonflies that can fly across oceans without resting or beetles that lay their eggs exclusively in corpses, but also the vital lessons we have learnt from them, including how therapy using maggots can save lives and how bees can help grow rich tomato yields.

The Hidden World reveals the wonderful complexity of our relationship with insects, how they have changed the course of our history and how, if we continue to learn from them, they could even be the key to our future and survival.

Jellyfish', a group that includes scyphomedusae, hydromedusae, siphonophores and ctenophores, are important zooplankton predators throughout the world's estuaries and oceans. These beautiful creatures have come to public attention as featured exhibits in aquaria and in news headlines as invaders and as providers of genes used in biomedical research. Nevertheless, jellyfish are generally considered to be nuisances because they interfere with human activities by stinging swimmers, clogging power plant intakes and nets of fishermen and fish farms, and competing with fish and eating fish eggs and larvae. There is concern that environmental changes such as global warming, eutrophication, and over-fishing may result in increased jellyfish populations. The literature reviews and research papers in this volume explore the interactions between jellyfish and humans. Papers cover the medical aspects of jellyfish stings, jellyfish as human food and jellyfish fisheries, interactions of jellyfish and fish, effects of environmental changes on jellyfish, effects of introduced ctenophores on the Black Sea ecosystem, factors causing increases or concentrations of jellyfish, and others aspects of jellyfish ecology. This is an important reference for students and professional marine biologists, oceanographers, fishery scientists, and aquarists.

During the past decade, the study of the chemical structures used by insects has advanced from a subject that could be reviewed in a single volume to a vastly more advanced level. This important new volume brings together a focused group of reviews that offer perspective on the most interesting advances in insect chemical ecology. Chemical Ecology of Insects 2 brings together an internationally respected group of experts covering such topics as chemoreception and integration, orientation mechanisms, plant-insect interactions and insect-insect interactions. An important benefit of these reviews lies in the identification of the boundaries of our current knowledge and the most profitable areas in which we should expect these areas to develop. This important work will appeal to entomologists and ecologists working directly with insects. In addition, plant scientists interested in the interaction of plants and insects will find much valuable information. The book is intended to benefit both field and laboratory researchers as well as advanced students.

An indispensable guide to identification, ecology and study of bumblebees.

The book introduces techniques and approaches to original work so that anyone with an interest can usefully contribute to furthering our understanding and appreciation of these wonderful and important insects.

This book aims at providing students and researchers an advanced integrative overview on zooplankton ecology, covering marine and freshwater organisms, from microscopic phagotrophic protists, to macro-jellyfishes and active fish larvae. The first book section addresses zooplanktonic organisms and processes, the second section is devoted to zooplankton spatial and temporal distribution patterns and trophic dynamics, and the final section is dedicated to emergent methodological approaches (e.g., omics). Book chapters include comprehensive synthesis, observational and manipulative studies, and sediment-based analysis, a vibrant imprint of benthic-pelagic coupling and ecosystem connectivity. Most chapters also address the impacts of anticipated environmental changes (e.g., warming, acidification).

Aeglidae focuses on these unique crustaceans who are endemic to South America. The book is the first to summarize the diverse aspects of the Aeglidae, whose taxonomic features and phylogenetic relationships, evolutionary history and biogeographical background, biological characteristics, and current conservation awareness make them stand out among all other decapods. Addresses the morphology, taxonomy, and phylogenetics that characterize the Aegla and their relationship to other decapod taxa Provides in-depth treatment of the evolutionary history, biogeography, reproduction, developmental biology, and the life cycle of the Aeglidae Discusses their physiology, ecology and behavior, including physiological mechanisms associated with freshwater adaptation, population dynamics, trophic ecology, agonistic and non-agonistic behavior Covers the current conservation status of all known species of aeglids, major threats to them, the use of aeglids as flagships or umbrella species, and conservation action planning Edited by internationally distinguished leaders in this field. This will be an important reference not only for carcinologists working with this family of decapods, but also readers interested in the evolution, biogeography, taxonomy, phylogenetics, physiology, and reproductive ecology.

This study examines the principles and practices of the Afikpo (Eugbo) Nigeria indigenous justice system in contemporary times. Like most African societies, the Afikpo indigenous justice system employs restorative, transformative and communitarian principles in conflict resolution. This book describes the processes of community empowerment, participatory justice system and how regular institutions of society that provide education, social and economic support are also effective in early intervention in disputes and prevention of conflicts.

The stingless bees are the most diverse group of highly social bees and are key species in our planet's tropical and subtropical regions, where they thrive. In Mexico, the management of stingless bees dates back centuries, and they were an essential part of the culture and cosmogony of native peoples like the Maya. In recent decades a vast amount of information has been gathered on stingless bees worldwide. This book summarizes various aspects of the biology and management of stingless bees, with special emphasis on the Mexican species and the traditions behind their cultivation. Much of the information presented here was produced by the author and the team of researchers at the Universidad Autonoma de Yucatan in the course of three decades of working with these insects. Given the breadth of its coverage, the book offers an equally valuable reference guide for academics, students and beekeepers alike.

Advances in Invertebrate (Neuro)Endocrinology: A Collection of Reviews in the Post-Genomic Era (2-volume set) provides an informative series of reviews from expert scientists who are at the forefront of their research into the endocrinology of invertebrates. These two volumes are timely and appropriate in this post-genomic era because of the rapid pace of change brought about by genome projects, functional genomics, and genetics (omics technologies). The volume shows the rich history and strong tradition of cutting-edge research using invertebrates that has opened up our broader understanding of comparative endocrinology and the evolution of regulatory pathways and systems. These reviews set the scene and context for this exciting new era of understanding that has come from this post-genomic revolution. This book undertakes the daunting task of covering most of the diverse endocrine systems that exist among invertebrates. The papers in this book will advance our knowledge of invertebrate endocrinology but also of endocrinology in general, making the book will be valuable to researchers and students.

In 1961, neurobiologists found that the conduction velocity of the nerve impulse in the giant nerve fiber of the" Penaeus "shrimp abdominal nerve cord was over 200 m/s, the highest speed of information transmission ever observed in the animal kingdom. The peculiar myelin sheath with its unique nodal structure and the electrical properties of the nerve fibers of the shrimp have continued to be investigated for a quarter of century and are now fully described in this book. The investigation dispels the commonly held belief that the fastest recorded impulse conduction is about 120 m/s in the thickest vertebrate myelinated nerve fibers. In the shrimp, researchers found a completely novel type of functional node in the giant fiber which they designated as the fenestration node. In portions of the myelinated fiber, the fenestration node furnished the sites of excitation. Also discovered was a new strategy for increasing impulse conduction in the shrimp. The book includes a section on the formation of the fenestration node and the discovery of a strategy that allows the shrimp to escape its predators by an action of the fastest velocity. The data presented in this volume on the myelin sheath of invertebrates present a new direction for this field and a rich source of information for neurobiologists worldwide.

This book provides updated information on this intriguing and exciting group of insects: Neotropical Social Wasps. These insects have a particular biology and their colonies are formed by a few cooperative females living in either small or massive, structured nests where stinging individuals organize their activities and defend their offspring. Topics include evolutionary aspects, biogeography, post-embryonic development, community behavior and ecology, economic importance, and research methods.

Recently, technological progress and the rise of DNA barcoding efforts have led to a significant increase in the availability of molecular datasets on intraspecific variability. Carcinologists and other organismal biologists, who want to use molecular tools to investigate patterns on the scale of populations, face a bewildering variety of genetic markers, analytical methods, and computer programs from which to choose. A modern overview of population genetic and phylogeographic studies, Phylogeography and Population Genetics in Crustacea offers insights to guide research on intraspecific genetic variation in crustaceans. Combining theory and case studies of current best practices, the book helps researchers select methods of analysis and interpret their results. The theoretical chapters discuss the potential of currently used and upcoming molecular markers in the context of marine non-model species. They also gather practical tips and address the effect of seldom-discussed sources of error, such as spatial and temporal variation, stochasticity, and choice of statistical parameters. Case studies of marine and limnic crustaceans from around the world highlight the importance and diversity of sources of population structure in intraspecific variation. Written by an international team of 46 leading experts, the book showcases the use and analysis of molecular markers, including mitochondrial and nuclear DNA sequence data, coding and non-coding sequences, microsatellites, and cytogenetics. It gives researchers and students a valuable summary of current knowledge on the processes that shape genetic variability and geographic distribution patterns in space and time.

Bivalve mollusks are roughly hand-sized animals that can aggregate into large groups of millions of individuals as reefs-pumping and filtering enough water in short periods of time to control the processes on the reef and adjacent tidal waters-and serve as valuable indicators and monitors of ecosystem health. Ecology of Marine Bivalves: An Ecosystems Approach, Second Edition examines the ecology of bivalves from an ecosystem or holistic view, taking into consideration their history, thermodynamics, components, and interactions with other species-namely humans. With the advent of the United Nations Millennium Ecosystem Assessment (MEA) in the year 2000, its emphasis for utilizing the ecosystem approach as a standard guideline, and the growing interest in global climate change, this edition has been expanded to include: A new chapter on shell rings, which emphasizes the importance of interaction between disciplines so that we might learn from the past in order to plan for the future Scientific work done on several continents, including case studies from the Chesapeake Bay, the Wadden Sea, and other case studies from Europe and New Zealand Additional material on non-equilibrium thermodynamics, complexity theory, and other cross-disciplinary interactions This book discusses the roles of marine bivalves as a keystone species and as ecosystem engineers, and explains how bivalves are used as monitors and indicators of ecosystem stress and as a fisheries resource. Utilizing case studies and targeted published research to develop narratives suitable for a complex systems approach, the second edition of Ecology of Marine Bivalves is invaluable to scientists and marine workers interested in an up-to-date treatment of mollusks in our seas.

In the English edition of his landmark book Endosymbiosis of Animals with Plant Microorganisms (1965), Professor Paul Buchner, probably the most prominent founder of systematic symbiosis research, wrote: ?I too soon fell victim to the spell of this subject, and from 1911 on devoted myself to it.? Almost half a century later, a growing number of entomologists are recognizing the impact that arthropod-bacteria symbiosis has on virtually all aspects of the biology of both host and symbiont. The discussion of this subject tends to be system based, with primary emphasis on the insect host. However, recent screening studies have revealed that the diversity of bacteria associated with arthropods may not be as wide as initially expected, and some genera are constantly being found in hosts that belong to distantly related taxa.

Manipulative Tenants: Bacteria Associated with Arthropods introduces the fascinating world of bacteria-arthropod associations with an emphasis on the bacterial partner. Written by an interdisciplinary team of international contributors, this book provides an overview of the diversity of bacterial symbionts identified to date as frequent partners of terrestrial arthropods. It discusses primary (obligatory) symbionts as well as the most abundant secondary (facultative) symbionts currently known.

Summarizing the most up-to-date information available on each symbiont, the book presents a synopsis of the field from the bacterial angle. Chapters examine Proteobacteria, including Sodalis and Wigglesworthia in tsetse flies and Stammerula and other symbiotic bacteria in fruit flies, as well as Bacteroidetes such as Blattabacterium and Cardinium. The book also identifies questions that emerge from the study of these systems. This comprehensive reference introduces the topic of bacteria-arthropod associations to researchers who are not familiar with it, enlarges the scope of knowledge of those who are, and provides a textbook for students in microbiology and other branches of biology.

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 invertebrates -- terrestrial, 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.
