This book reviews the physiological mechanisms of diverse insect clocks, including circadian clock, lunar clock, tidal clock, photoperiodism, circannual rhythms and others. It explains the commonality and diversity of insect clocks, focusing on the recent advances in their molecular and neural mechanisms. In the history of chronobiology, insects provided important examples of diverse clocks. The first report of animal photoperiodism was in an aphid, and the time-compensated celestial navigation was first shown in the honeybee. The circadian clock was first localized in the brain of a cockroach. These diverse insect clocks also have some common features which deserve to be reviewed in a single book. The central molecular mechanism of the circadian clock, i.e., the negative feedback loop of clock genes, was proposed in Drosophila melanogaster in the 1990s and later became the subject of the Nobel Prize in Physiology or Medicine in 2017. Thereafter, researches on the molecular and neural mechanisms in diverse insect clocks other than the Drosophila circadian clock also advanced appreciably. Various new methods including RNAi, NGS, and genome editing with CRISPR-Cas9 have become applicable in these researches. This book comprehensively reviews the physiological mechanisms in diverse insect clocks in the last two decades, which have received less attention than the Drosophila circadian clock. The book is intended for researchers, graduate students, and highly motivated undergraduate students in biological sciences, especially in entomology and chronobiology.

This volume presents a series of case studies, at different levels of inclusivity, of how organisms exhibit functional convergence as a key evolutionary mechanism resulting in responses to similar environmental constraints in mechanically similar ways. The contributors to this volume have selected and documented cases of convergent evolution of form and function that are perceived to be driven by environmental abiotic and/or biotic challenges that fall within their areas of expertise. Collectively these chapters explore this phenomenon across a broad phylogenetic spectrum. The sequence of chapters follows the organizational principle of increasing phylogenetic inclusivity, rather than the clustering of chapters by perceived similarity of the phenotypic features or biomechanical challenges being considered. This is done to maintain focus on the evolutionary phenomenon that is the primary subject matter of the book, thereby providing a basis for discussion among the readership about whatis necessary and sufficient to justify the recognition of functional convergence. All chapters stress the need for integrative approaches for the elucidation of both pattern and process as they relate to convergence at various taxonomic levels.

The book appeals to all those interested in communication and vibrational behavior.

This book offers a range of environmentally benign molecular mechanisms which are safer alternative strategies for effective insect pest management. In modern era of biotechnology, there has been much advancement in the field of molecular biology, where many more techniques have evolved which can be helpful in the field of pest management too. Plant resistance, development of transgenic plants, and many more techniques are being considered the panacea to pest problems. On the other hand, there are wide spread concerns of the safety of biotechnological interventions with nontarget organisms including humans. While the world stands divided on the ethical issues of these approaches and the many safety concerns, scientists believe that well thought of biotechnological interventions are probably the only safest ways possible for reducing pest attacks on crops. It explores various techniques and aspects related to molecular pathways for crop pest control. This book is a useful resource for postgraduate students and researchers of agriculture sciences, plant pathology and plant physiology. It is also useful for policy planners in agriculture.

Owing to their unique state of preservation, mummies provide us with significant historical and scientific knowledge of humankind's past. This handbook, written by prominent international experts in mummy studies, offers readers a comprehensive guide to new understandings of the field's most recent trends and developments. It provides invaluable information on the health states and pathologies of historic populations and civilizations, as well as their socio-cultural and religious characteristics. Addressing the developments in mummy studies that have taken place over the past two decades – which have been neglected for as long a time – the authors excavate the ground-breaking research that has transformed scientific and cultural knowledge of our ancient predecessors. The handbook investigates the many new biotechnological tools that are routinely applied in mummy studies, ranging from morphological inspection and endoscopy to minimally invasive radiological techniques that are used to assess states of preservation. It also looks at the paleoparasitological and pathological approaches that have been employed to reconstruct the lifestyles and pathologic conditions of ancient populations, and considers the techniques that have been applied to enhance biomedical knowledge, such as craniofacial reconstruction, chemical analysis, stable isotope analysis and ancient DNA analysis. This interdisciplinary handbook will appeal to academics in historical, anthropological, archaeological and biological sciences, and will serve as an indispensable companion to researchers and students interested in worldwide mummy studies.

Microbial biotechnology is an emerging field with applications in a broad range of sectors involving food security, human nutrition, plant protection and overall basic research in the agricultural sciences. The environment has been sustaining the burden of mankind from time immemorial, and our indiscriminate use of its resources has led to the degradation of the climate, loss of soil fertility, and the need for sustainable strategies. The major focus in the coming decades will be on achieving a green and clean environment by utilizing soil and plant-associated beneficial microbial communities. Plant-microbe interactions include the association of microbes with plant systems: epiphytic, endophytic and rhizospheric. The microbes associated with plant ecosystems play an important role in plant growth, development, and soil health. Moreover, soil and plant microbiomes help to promote plant growth, either directly or indirectly by means of plant growth-promoting mechanisms, e.g.the release of plant growth regulators; solubilization of phosphorus, potassium and zinc; biological nitrogen fixation; or by producing siderophores, ammonia, HCN and other secondary metabolites. These beneficial microbial communities represent a novel and promising solution for agro-environmental sustainability by providing biofertilizers, bioprotectants, and biostimulants, in addition to mitigating various types of abiotic stress in plants. This book focuses on plant-microbe interactions; the biodiversity of soil and plant microbiomes; and their role in plant growth and soil health. Accordingly, it will be immensely useful to readers working in the biological sciences, especially microbiologists, biochemists and microbial biotechnologists.

In conclusion, the book addresses new aspects like the biofabrication of nanoparticles and their application in plant disease management, and presents an extensive list for further reading.

Insects engage in intimate associations with microbial symbionts that colonize their digestive systems or internal cells and tissues. The stability and near ubiquity of many of these'symbioses'implies their importance, a prediction supported through experimentation. With the advancing power of experimental methodologies and the growing accessibility of genomic techniques, insect science has reached a powerful new stage enabling the study of previously recalcitrant symbioses, including several with medical and agricultural significance. In this volume we publish a collection of chapters focused on the physiology of insect-microbe symbioses, emphasizing their mechanistic underpinnings, and the ecological and evolutionary causes and consequences of these interactions. Resident microbes modulate insect digestion, nutrition, detoxification, reproduction, interspecies signaling, and host-parasite interactions, and these chapters synthesize impactful, state-of-the art research on insect-microbe symbioses. Through discussions of the mechanisms that both stabilize and regulate these symbioses, these chapters yield further insight into the physiological integration between many insects and their influential microbial partners. - A broad look at the wide range of symbiont roles and impacts throughout Insecta - Molecular and genomic-assisted insights into the diversity and function of symbioses - Insights into the influence and integration of symbionts from medically and agriculturally important insects

Part 2 presents an update on the use of essential oils in various areas, including food and pharma industries as well as agriculture. In part 3 readers will find new trends in bioanalytical methods. Lastly, part 4 presents a number of approaches to increase essential oil production, such as in vitro and hairy root culture, metabolic engineering and biotechnology. Altogether, this volume offers a comprehensive look at what researchers have been doing over the last years to better understand these compounds and how to explore them for the benefit of the society.

This updated monograph deals with methanogenic endosymbionts of anaerobic protists, in particular ciliates and termite flagellates, and with methanogens in the gastrointestinal tracts of vertebrates and arthropods. Further chapters discuss the genomic consequences of living together in symbiotic associations, the role of methanogens in syntrophic degradation, and the function and evolution of hydrogenosomes, hydrogen-producing organelles of certain anaerobic protists. Methanogens are prokaryotic microorganisms that produce methane as an end-product of a complex biochemical pathway. They are strictly anaerobic archaea and occupy a wide variety of anoxic environments. Methanogens also thrive in the cytoplasm of anaerobic unicellular eukaryotes and in the gastrointestinal tracts of animals and humans. The symbiotic methanogens in the gastrointestinal tracts of ruminants and other “methanogenic” mammals contribute significantly to the global methane budget; especially therumen hosts an impressive diversity of methanogens. This makes this updated volume an interesting read for scientists and students in Microbiology and Physiology.

This book discusses the controversial and conflicting hypotheses on the origin of angiosperms, which was generally assumed to be restricted to the Cretaceous and later ages. Since publishing the first edition of “The Dawn of Angiosperms” in 2010, several important advances have been made in this field of science, namely 1) the discovery of new fossil angiosperms from the Jurassic; 2) European researchers discovering angiosperm-like pollen from the Triassic; and most importantly 3) the discovery of a perfect flower from the Jurassic. All of these findings are at odds with the currently widely accepted evolutionary theories, and thus call upon us to critically reassess botanical theory. Accordingly, the new edition of this book not only includes more new fossil taxa, but also documents them in greater detail and corrects many commonly held misconceptions. In so doing, it makes related studies and teaching on the early history of angiosperms more realistic, concrete, andtangible, providing concrete fossil evidence as the basis for future research, and helping to distinguish the most accurate botanical hypotheses.

This book presents research on volatiles produced by microbes and plants along with their biotechnological implications for sustainable agriculture. A greater understanding of how plants and microbes live together and benefit each other can provide new strategies to improve plant productivity, while at the same time helping to protect the environment and maintain global biodiversity. To date, the use of chemicals to enhance plant growth or induced resistance in plants has been limited due to the negative effects and the difficulty in determining the optimal concentrations to benefit the plant. The book discusses extensive studies on biological alternatives that avoid these problems, and the research presented suggests that these compounds could offer an environmentally sound means to better grow and protect plants under greenhouse or field conditions. To understand the nature of VOCs and gene expression profiling of plant genes responding against these compounds can be conducted. Itis possible that VOCs produced by microbes while colonizing roots are generated at sufficient concentrations to trigger plant responses. In conclusion, positive or negative effects of VOCs on plant productivity will be dependent on upon specific VOCs microbial strain, plant genotype, and presence/absence of abiotic/biotic stresses

Emphasis is placed on the elaborate cuticular matrices in insects and crustaceans, spider and insect silks, sialomes of phytophagous and blood-feeding arthropods as well as on secretions of male and female accessory glands. Focus is placed largely on insects, due to the extensive body of published research that in part is the result of available whole genome sequences of several model species (in particular Drosophila melanogaster) and accessible ESTs for other species. Such advances have facilitated fundamental insights into genomic, proteomic and molecular biology-based physiology. This new volume contains comprehensive contributions on extracellular composite matrices in arthropods. The building blocks of such matrices are formed in and secreted by single layered epithelial cells into exterior domains where their final assembly takes place.Additionally, the unique mechanical properties of natural biocomposites like chitin/chitosan, the crustacean mineralized exoskeleton, the pliant protein resilin or insect and spider silks, have inspired basic and applied research that yield sophistical biomimetics and structural biocomposite hybrids important for future industrial and biomedical use. In summary, this book provides an invaluable vast source of basic and applied information for a plethora of scientists as well as textbook for graduate and advanced undergraduate students.

This book provides a comprehensive review of the evolution of traits associated with predation and predator defense for bats and all of their prey, both invertebrates (e.g. insects) and vertebrates (e.g. frogs), in the context of co-evolution. It reviews current knowledge of how echolocation and passive hearing are used by bats to hunt prey in complete darkness. Also it highlights how prey have evolved counter measures to bat echolocation to avoid detection and capture. This includes the whole range of prey responses from being active at times when bats are inactive to the use of acoustic signals of their own to interfere with the echolocation system of bats.

This volume summarizes recent advances in our understanding of the mechanisms that produce successful symbiotic partnerships involving microorganisms. It begins with a basic introduction to the nature of and mechanistic benefits derived from symbiotic associations. Taking that background knowledge as the starting point, the next sections include chapters that examine representative examples of coevolutionary associations that have developed between species of microbes, as well as associations between microbes and plants. The authors conclude with a section covering a broad range of associations between microbes and invertebrate animals, in which they discuss the spectrum of hosts, with examples ranging from bryozoans and corals to nematodes, arthropods, and cephalopods. Join the authors on this journey of understanding!

The interactions between the plant, soil and microbes are complex in nature. Events may be antagonistic, mutualistic or synergistic, depending upon the types of microorganisms and their association with the plant and soil in question. Multi-trophic tactics can therefore be employed to nourish plants in various habitats and growth conditions. Understanding the mechanisms of these interactions is thus highly desired in order to utilize the knowledge in an ecofriendly and sustainable way. This holistic approach to crop improvement may not only resolve the upcoming food security issues, but also make the environment greener by reducing the chemical inputs. Plant, soil and microbe, Volume 1: Implications in Crop Science, along with the forthcoming Volume 2: Mechanisms and Molecular Interactions, provide detailed accounts of the exquisite and delicate balance between the three critical components of agronomy. Specifically, these two titles focus on the basis of nutrient exchange between the microorganisms and the host plants, the mechanism of disease protection and the recent molecular details emerged from studying this multi-tropic interaction. Together they aim to provide a solid foundation for the students, teachers, and researchers interested in soil microbiology, plant pathology, ecology and agronomy.

Bananas and plantains are among the most important food and cash crops in the world. They are cultivated in more than 135 countries, across the tropics and subtropics, with an annual global production of ca. 130 million metric tonnes. Though bananas are one of the most important components of food security in many developing countries, banana production is threatened by both abiotic and biotic stresses. These include a wide range of diseases and pests, such as bunchy top virus, burrowing nematodes, black Sigatoka or black leaf streak, Fusarium wilt, etc. In recent years, considerable progress has been made and several biotechnological and genomic tools have been employed to help understand and unravel the mysterious banana genome. Molecular and genomic studies have helped to decipher the Musa genome and its evolution. Genetic linkage map and whole genome sequencing of both Musa acuminata and Musa balbisiana (progenitors of cultivated banana) have completely changedthe way of thinking and the approach on banana crop improvement. Whole-genome sequencing has helped to improve the selection of quantitative traits such as yield, as well as the selection of optimal parents for developing required hybrids in breeding programs. Gene isolation and the analysis of mutants have helped in the characterization of genes of agronomic value and the associated regulatory sequences. With the advent of molecular markers and new statistical tools, it is now possible to measure the diversity, identify genes and useful alleles linked to important agronomic traits. Further these alleles can be incorporated into cultivars through marker assisted selection or through transgenic approach. Transgenic approaches are potential tools for direct transfer of these genes into popular cultivars, which are generally not amenable for conventional breeding techniques, in specific with crops such as bananas which are sterile, triploid and heterozygous thereby making itdifficult to reconstruct the recurrent genotypes in banana. Transgenic techniques thus have helped overcome the difficulty of working with sterile, triploid banana crop. In the last five years, enormous amount of new information and techniques have been generated for banana. A comprehensive book entitled “Banana: Genomics and Transgenic Approaches for Genetic improvement” on banana genomics, latest transgenic technologies and tools available for improved crop development in banana will address all these requirements.

This volume offers a much-needed compilation of essential reviews on diverse aspects of plant biology, written by eminent botanists. These reviews effectively cover a wide range of aspects of plant biology that have contemporary relevance. At the same time they integrate classical morphology with molecular biology, physiology with pattern formation, growth with genomics, development with morphogenesis, and classical crop-improvement techniques with modern breeding methodologies. Classical botany has been transformed into cutting-edge plant biology, thus providing the theoretical basis for plant biotechnology.It goes without saying that biotechnology has emerged as a powerful discipline of Biology in the last three decades. Biotechnological tools, techniques and information, used in combination with appropriate planning and execution, have already contributed significantly to economic growth and development. It is estimated that in the next decade or two, products and processes made possible by biotechnology will account for over 60% of worldwide commerce and output. There is, therefore, a need to arrive at a general understanding and common approach to issues related to the nature, possession, conservation and use of biodiversity, as it provides the raw material for biotechnology. More than 90% of the total requirements for the biotechnology industry are contributed by plants and microbes, in terms of goods and services. There are however substantial plant and microbial resources that are waiting for biotechnological exploitation in the near future through effective bioprospection. In order to exploit plants and microbes for their useful products and processes, we need to first understand their basic structure, organization, growth and development, cellular process and overall biology. We also need to identify and develop strategies to improve the productivity of plants.In view of the above, in this two-volume book on plant biology and biotechnology, the first volume is devoted to various aspects of plant biology and crop improvement. It includes 33 chapters contributed by 50 researchers, each of which is an expert in his/her own field of research. The book begins with an introductory chapter that gives a lucid account on the past, present and future of plant biology, thereby providing a perfect historical foundation for the chapters that follow. Four chapters are devoted to details on the structural and developmental aspects of the structures of plants and their principal organs. These chapters provide the molecular biological basis for the regulation of morphogenesis of the form of plants and their organs, involving control at the cellular and tissue levels. Details on biodiversity, the basic raw material for biotechnology, are discussed in a separate chapter, in which emphasis is placed on the genetic, species and ecosystem diversities and their conservation.Since fungi and other microbes form an important component ofthe overall biodiversity, special attention is paid to the treatment of fungi and other microbes in this volume. Four chapters respectively deal with an overview of fungi, arbuscularmycorrhizae and their relation to the sustenance of plant wealth, diversity and practical applications of mushrooms, and lichens (associated with a photobiont). Microbial endosymbionts associated with plants and phosphate solubilizing microbes in the rhizosphere of plants are exhaustively treated in two separate chapters. The reproductive strategies of bryophytes and an overview on Cycads form the subject matter of another two chapters, thus fulfilling the need to deal with the non-flowering Embryophyte group of plants.Angiosperms, the most important group of plants from a biotechnological perspective, are examined exhaustively in this volume. The chapters on angiosperms provide an overview and cover the genetic basis of flowers development, pre-and post-fertilization reproductive growth and developme

Readers familiar with the first three editions of Ecology and Classification of North American Freshwater Invertebrates (edited by J.H. Thorp and A.P. Covich) will welcome the comprehensive revision and expansion of that trusted professional reference manual and educational textbook from a single North American tome into a developing multi-volume series covering inland water invertebrates of the world. The series entitled Thorp and Covich's Freshwater Invertebrates (edited by J.H. Thorp) begins with the current Volume I: Ecology and General Biology (edited by J.H. Thorp and D.C. Rogers), which is designed as a companion volume for the remaining books in the series. Those following volumes provide taxonomic coverage for specific zoogeographic regions of the world, starting with Keys to Nearctic Fauna (Vol. II) and Keys to Palaearctic Fauna (Vol. III). Volume I maintains the ecological and general biological focus of the previous editions but now expands coverage globally in all chapters, includes more taxonomic groups (e.g., chapters on individual insect orders), and covers additional functional topics such as invasive species, economic impacts, and functional ecology. As in previous editions, the 4th edition of Ecology and Classification of North American Freshwater Invertebrates is designed for use by professionals in universities, government agencies, and private companies as well as by undergraduate and graduate students. - Global coverage of aquatic invertebrate ecology - Discussions on invertebrate ecology, phylogeny, and general biology written by international experts for each group - Separate chapters on invasive species and economic impacts and uses of invertebrates - Eight additional chapters on insect orders and a chapter on freshwater millipedes - Four new chapters on collecting and culturing techniques, ecology of invasive species, economic impacts, and ecological function of invertebrates - Overall expansion of ecology and general biology and a shift of the even more detailed taxonomic keys to other volumes in the projected 9-volume series - Identification keys to lower taxonomic levels

Entomology is a super science, embracing interdisciplinary approaches in genomics, proteomics, and interdependent fields of biochemistry, physiology, molecular entomology, and biotechnology. An urgent need to manage available resources for the benefit of the planet and humankind has led to remarkable progress since publication of the fruit fly genome in 2000. “Short Views on Insect Genomics and Proteomics” presents multiple perspectives of recognized experts from around the world in genomics, bioinformatics, molecular biology, biochemistry, physiology, and immunology, emphasizing fast-moving areas of current research on insects and other arthropods. Concise, accessible, topical reviews include body lice and white fly genome projects, aphid phenotypic plasticity, insect regulatory genomics, the complex tick sialome, protein expression systems, therapeutic potential of insect antimicrobial peptides, nanoparticle insecticides, and novel uses for recombinant and synthetic spider silks.

Every coordination within or between animals depends on communication processes. Although the signaling molecules, vocal and tactile signs, gestures and its combinations differ throughout all species according their evolutionary origins and variety of adaptation processes, certain levels of biocommunication can be found in all animal species: (a) Abiotic environmental indices such as temperature, light, water, etc. that affect the local ecosphere of an organism and are sensed, interpreted. (b) Trans-specific communication with non-related organisms.(c) Species-specific communication between same or related species. (d) Intraorganismic communication, i.e., sign-mediated coordination within the body of the organism. This book gives an overview of the manifold levels of animal communication exemplified by a variety of species and thereby broadens the understanding of these organisms.

The 11th International Symposium on Insect-Plant Relationships (SIP11), held on August 4-10, 2001, in Helsingør, Denmark, followed the tradition of previous SIP meetings and covered topics of different levels from chemistry, physiology, and ethology to ecology, genetics, and evolution of insect-plant relationships. The present volume includes a representative selection of fully refereed papers as well as a complete list of all the contributions which were presented at the meeting. Reviews of selected topics as well as original experimental data are included. The book provides valuable information for students and research workers interested in chemical and biological aspects of interactions between individuals and populations of different organisms.

JOHN G. HILDEBRAND Research on insect olfaction is important for at least two reasons. First, the olfactory systems of insects and their arthropod kin are experi­ mentally favourable models for studies aimed at learning about general principles of olfaction that apply to vertebrates and invertebrates alike. Detailed comparisons between the olfactory pathways in vertebrates and insects have revealed striking similarities of functional organisation, physiol­ ogy, and development, suggesting that olfactory information is processed through neural mechanisms more similar than different in these evolution­ arily remote creatures. Second, insect olfaction itself is important because of the economic and medical impact of insects that are agricultural pests and disease vectors, as well as positive impact of beneficial species, such as the bees and moths responsible for pollination and production of honey. The harm or benefit attributable to an insect is a function of what it does - that is, of its behaviour - which is shaped by sensory information. Often olfaction is the key modality for control of basic insect behaviour, such as ori­ entation and movement toward, and interactions with, potential mates, appro­ priate sites for oviposition, and sources of food. Not surprisingly, therefore, much work on insect olfaction has been motivated by long-term hopes of using knowledge of this pivotal sensory system to design strategies for mon­ itoring and managing harmful species and fostering the welfare of beneficial ones.

This book represents the proceedings of a NATO Advanced Research Workshop of the same name, held at St. Andrews University, Scotland in July of 1989. It was the first meeting of its kind and was convened as a forum to review and discuss the phylogeny of some of the cell biological functions that underlie nervous system function, such matters as intercellular communication in diverse, lower organisms, and the electrical excitability of protozoans and cnidarians, to mention but two. The rationale behind such work has not necessarily been to understand how the first nervous systems evolved; many of the animals in question provide excellent opportunities for examining general questions that are unapproachable in the more complex nervous systems of higher animals. Nevertheless, a curiosity about nervous system evolution has invariably pervaded much of the work. The return on this effort has been mixed, depending to a large extent on the usefulness of the preparation under examination. For example, work on cnidarians, to many the keystone phylum in nervous system evolution simply because they possess the'first'nervous systems, lagged behind that carried out on protozoans, because the latter are large, single cells and, thus, far more amenable to microelectrode-based recording techniques. Furthermore, protozoans can be cultured easily and are more amenable to genetic and molecular analyses.

In March 1996 the Society of Experimental Biology (UK) together with two other international scientific societies, the Australian and New Zealand Society for Comparative Physiology and Biochemistry and the Society for Integrative and Comparative Biology (formally the American Society for Zoology) joined forces with Springer-Verlag, Heidelberg to produce one of the first fully electronic online, peer-reviewed biological journals, Experimental Biology Online. The present product represents the fruits of this joint venture and encapsulates Volumes 1 and 2 of the journal. This will be an ongoing series such that an archival version of the journal will be available to all libraries as well as the on-line version. At the outset this was'new land'for all concerned but the launching of a journal which would cover experimental biology in terms of Animal, Cell and Plant topics was daunting but we all felt that the use of electronic media and the internet would be ideally suited to this purpose.

With over 43,000 species, spiders are the largest predacious arthropod group. They have developed key characteristics such as multi-purpose silk types, venoms consisting of hundreds of components, locomotion driven by muscles and hydraulic pressure, a highly evolved key-lock mechanism between the complex genital structures, and many more unique features. After 300 million years of evolutionary refinement, spiders are present in all land habitats and represent one of the most successful groups of terrestrial organisms.Ecophysiology combines functional and evolutionary aspects of morphology, physiology, biochemistry and molecular biology with ecology. Cutting-edge science in spiders focuses on the circulatory and respiratory system, locomotion and dispersal abilities, the immune system, endosymbionts and pathogens, chemical communication, gland secretions, venom components, silk structure, structure and perception of colours as well as nutritional requirements. Spiders are valuable indicator species in agroecosystems and for conservation biology. Modern transfer and application technologies research spiders and their products with respect to their value for biomimetics, material sciences, and the agrochemical and pharmaceutical industries.

Kevin Marshall is a hard act to follow. Volume 13 of Advances in Microbial Ecology has been produced by a new editorial board, and we, the members of that board, are delighted to have the opportunity to pay tribute to Kevin's achievements. In his time as Series Editor, the quality of the chapters submitted and the range of subject matter covered have ensured an expanding and more stimulated readership. This represents a considerable achievement, given the growth in the number of review volumes and the increasing tendency for journals to publish review articles. The achievement was reached not only through metic­ ulous attention to quality and detail but also by providing a forum for the expression of views, information, and results that would stimulate discussion. Advances in Microbial Ecology will continue to provide such a focus, although, because of the frequency of publication, it would not be practicable to introduce a'reply'or'comment'section. Although we do not deliberately aim to provide a forum for controversy, we encourage speculation based on sound scientific arguments. In addition, we would like to encourage authors to offer chapters for consideration. In the past, the volumes have largely comprised invited chapters. With the best will in the world, an editorial board of four cannot claim adequate coverage of such a vast and rapidly developing research area. We would there­ fore welcome submission of outline plans for chapters, which should be sent to the Editor.

The study of animal communication has led to significant progress in our general understanding of motor and sensory systems, evolution, and speciation. However, one often neglected aspect is that signal exchange in every modality is constrained by noise, be it in the transmission channel or in the nervous system. This book analyses whether and how animals can cope with such constraints, and explores the implications that noise has for our understanding of animal communication. It is written by leading biologists working on different taxa including insects, fish, amphibians, lizards, birds, and mammals. In addition to this broad taxonomic approach, the chapters also cover a wide array of research disciplines: from the mechanisms of signal production and perception, to the behavioural ecology of signalling, the evolution of animal communication, and conservation issues. This volume promotes the integration of the knowledge gained by the diverse approaches to the study of animal communication and, at the same time, highlights particularly interesting fields of current and future research.

Allelopathy is an ecological phenomenon by which plants release organic chemicals (allelochemicals) into the environment influencing the growth and survival of other organisms. In this book, leading scientists in the field synthesize latest developments in allelopathy research with a special emphasis on its application in sustainable agriculture. The following topics are highlighted: Ecological implications, such as the role of allelopathy during the invasion of alien plant species; regional experiences with the application of allelopathy in agricultural systems and pest management; the use of microscopy for modeling allelopathy; allelopathy and abiotic stress tolerance; host allelopathy and arbuscular mycorrhizal fungi; allelopathic interaction with plant nutrition; and the molecular mechanisms of allelopathy. This book is an invaluable source of information for scientists, teachers and advanced students in the fields of plant physiology, agriculture, ecology, environmental sciences, and molecular biology.

Fourteen years have passed since the publication of David Spencer Smith's Insect Cells: Their Structure and Function. Here the results of a decade of electronmicroscopic studies on insect cells were summarized in an organized and integrated fashion for the first time, and the ultrastructural characteristics of different specialized cells and tissues were abundantly illustrated in the 117 plates this monograph contained. In the intervening period great progress has been made in the field of Insect Ultrastructure. Organelles not even mentioned in Smith's book, such as synaptonemal complexes, clathrin baskets, fusomes, and retinular junc­ tions, have been identified and functions proposed for them. There have also been many technical advances that have profoundly influenced the direction of subsequent research. A spectacular example would be the development by Miller and Beatty of the chromosomal spreading technique which allowed for the first time ultrastructural studies on segments of chromosomes containing genes in various stages of replication and transcription. Then there is the freeze-fracture procedure first described by Moor and his colleagues. This technique permitted an analysis of intercellular junctions that was impossible with the conventional sectioning methods. The results greatly clarified our understanding of the channels for ion movement and the permeability barriers between cells and also the membrane changes that occur during the embryonic differentiation and metamorphosis of various types of insect cells.

This volume contains the scientific papers and abstracts of posters presented at the International Symposium on Molecular Insect Science held in Tucson, Arizona, October 22-27, 1989. This meeting was organized by the Center for Insect Science at the University of Arizona in response to the growing need for a forum dedicated to the impact of modern biology on insect science. While scientific studies of a few insects, notably Drosophila melanogaster, have always had a central role in the development of biology, it is only recently that tools have become available to extend these studies to other insects, including those having economic and medical importance. The Tucson meeting was evidence of how far we have come in extending modern biological tools to the study of insects. It is also evident from the contents of this book that the study of insects is making an increasingly important contribution to the advancement of biology generally. Given the large impact of insects on human life, such a development has considerable importance for human welfare, and of the welfare of the ecosystem as a whole. It should be noted that several of the participants who presented posters were invited to prepare full length papers to ensure that the book covered the major areas of insect science. The financial support of the National Science Foundation and the Monsanto Corporation is gratefully acknowledged. Thanks are also due to Sharon Richards for her dedicated work on the manuscripts.

Principles of Insect Pathology, a text written from a pathological viewpoint, is intended for graduate-level students and researchers with a limited background in microbiology and in insect diseases. The book explains the importance of insect diseases and illuminates the complexity and diversity of insect-microbe relationships. Separate sections are devoted to the major insect pathogens, their characteristics, and their life cycles the homology that exists among invertebrate, vertebrate, and plant pathogens the humoral and cellular defense systems of the host insect as well as the evasive and suppressive activities of insect disease agents the structure and function of passive barriers the heterogeneity in host susceptibility to insect diseases and associated toxins the mechanisms regulating the spread and persistence of diseases in insects. Principles of Insect Pathology combines the disciplines of microbiology (virology, bacteriology, mycology, protozoology), pathology, and immunology within the context of the insect host, providing a format which is understandable to entomologists, microbiologists, and comparative pathologists.

G.P. Stamou describes the adaptive strategies that allow arthropods to cope with the severity of Mediterranean environments. After an introduction to the structure and function of Mediterranean-type ecosystems, ecophysiological adaptations to water stress and varying temperature are considered. Further, activity patterns and life cycle tactics are discussed in relation to the peculiarity of Mediterranean environments. Phenological patterns and population dynamics as well as community structures are also presented. The volume ends with a synthesis of life history tactics.

Comparisons are made of the adaptations of invertebrates from polar deserts with those of temperate and subtropical deserts. These regions represent some of the most hostile environments on earth and an array of strategies for survival has been developed. Polar species are well adapted to cold and experience arid conditions due to low precipitation and lack of liquid water during the winter. Similarly, temperate desert invertebrates are adapted to dry conditions and are also exposed to low winter temperatures. Terrestrial arthropods maintain their water balance through behavioural and physiological adaptations. Tardigrades and nematodes are remarkable in their ability to lose all their water, enter a state of anhydrobiosis and be revived when moisture becomes available again.

Ecology is characterized by a rapidly growing complexity and diversity of facts, aspects, examples, and observations. What is badly needed is the development of common patterns, of rules that, as in other sciences such as physics, can more generally explain the increasing complexity and variability we observe. Tom White, being one of the'seniors'in ecology, makes such an attempt in his book. the pattern he shows and explains with numerous examples from the entire animal kingdom is a universal hunger for nitrogen, a misery that drives the ecology of all organisms. He advocates that the awareness of this fundamental role that the limitation of nitrogen plays in the ecology of all organisms should be as a much part of each ecologis's intellectual equipment as is the awareness of the fact of evolution by means of natural selection. His claim is that not'enery'but'nitrogen'is the most limited'currency'in the animal world for the production and growth of their young.

There are over a million different species of insects, and individually they 8 outnumber humans by more than 10 to 1. Moreover, some insects live in close association with both plants and higher animals and naturally exchange viruses with them. It has even been speculated that viruses in general may have radiated through the plant and animal kingdoms from common insect origins. Be that as it may, since insects play pivotal roles in the biosphere, both to the benefit and detriment of mankind, they and the viruses that infect them are important subjects for study. Insects are infected by a diverse medley of viruses, and this volume focuses on those insect virus families that are found primarily or exclusively in insects. All major families of insect-selective viruses are covered except for the baculo­ viruses, which were described in a separate volume of The Viruses series. Included in this volume are the established families of insect viruses, the newly recognized ascovirus family, and the nudiviruses, which probably represent a separate family but currently remain unclassified. The coverage of arboviruses is limited to a single chapter that focuses on their potential utility as vectors and in insect control. Omitted for practical reasons are several individual insect viruses that have been described sporadically in the literature and probably represent novel virus families.

Surprising though it seems, the world faces almost as great a threat today from arthropod-borne diseases as it did in the heady days of the 1950s when global eradication of such diseases by eliminating their vectors with synthetic insecticides, particularly DDT, seemed a real possibility. Malaria, for example, still causes tremendous morbidity and mortality throughout the world, especially in Africa. Knowledge of the biology of insect and arachnid disease vectors is arguably more important now than it has ever been. Biological research directed at the development of better methods of control becomes even more important in the light of the partial failure of many control schemes that are based on insecticide- although not all is gloom, since basic biological studies have contributed enormously to the outstanding success of international control programmes such as the vast Onchocerciasis Control Programme in West Africa. It is a sine qua non for proper understanding of the epidemiology and successful vector control of any human disease transmitted by an arthropod that all concerned with the problem - medical entomologist, parasitologist, field technician - have a good basic understanding of the arthropod's biology. Knowledge will be needed not only of its direct relationship to any parasite or pathogen that it transmits but also of its structure, its life history and its behaviour - in short, its natural history. Above all, it will be necessary to be sure that it is correctly identified.
