The Whitefly, Bemisia tabaci (Homoptera: Aleyrodidae) Interaction with Geminivirus-Infected Host Plants

by Winston M.O. Thompson

The book presents a chronology of events of B. tabaci and geminiviruses, and an overview within the Caribbean and Latin America. The pathosystems involving Tomato yellow leaf curl virus, Cotton leaf curl virus and the cassava mosaic viruses are discussed. Data is presented on amino acid concentrations influencing B. tabaci and thus serves the basis for holidic diets. The essential molecular techniques for B. tabaci identification and classification are included with factors to consider for appropriate applications; an essential working guide for graduate students and researchers in the molecular field. Excellent photos portray symptoms of geminivirus-infecting crops: tomato, cotton, cassava, legumes and cucurbits; an important guide for researchers and growers. The novel insecticides, their mode of action and specificity; emphasize the applications of these within IPM programs.

Identification Guide of Freshwater Macroinvertebrates of Spain

by David Galicia Javier Oscoz Rafael Miranda

As a result of the European Commission's concern for the status of continental waters, and as a clear reflection of the notion of water as heritage to be conserved, in the year 2000 the Water Framework Directive (2000/60/CE) was enacted, its goal being to establish a framework to protect water and the different aquatic ecosystems by requiring the Member States to achieve a good ecological status in all their waters by 2015. Like all ecosystems, freshwater ecosystems undergo physical, chemical and energy-related changes, both of natural and anthropogenic origin. These disturbances affect the organisms living in them and those who utilize their resources. Therefore, evaluating these changes has become a very important task in order to better understand aquatic systems. The study and analysis of the ecological status of these ecosystems in relation to their conservation status and water quality is thus a fundamental tool for a more efficient and rational management of their resources, that is, a management that does not threaten the ecosystem. The present guide for the identification of Spanish freshwater macroinvertebrates aims to facilitate the job of those who go to great lengths to identify them in order to then determine biotic indices. It is not the aim of this book to serve as a zoological treaty, nor does it claim to add new information on the biology or the ecology of the taxa covered. This book is, simply, a working tool explicitly designed to facilitate the identification of the Spanish macroinvertebrates and the subsequent computing of biotic indices.

Sustaining Young Forest Communities

by Beverly Collins Frank Thompson III Cathryn Greenberg

This edited volume addresses a rising concern among natural resource scientists and management professionals about decline of the many plant and animal species associated with early-successional habitats, especially within the Central Hardwood Region of the USA. These open habitats, with herbaceous, shrub, or young forest cover, are disappearing as abandoned farmland, pastures, and cleared forest patches return to forest. There are many questions about "why, what, where, and how" to manage for early successional habitats. In this book, expert scientists and experienced land managers synthesize knowledge and original scientific work to address questions on such topics as wildlife, water, carbon sequestration, natural versus managed disturbance, future scenarios, and sustainable creation and management of early successional habitat in a landscape context.

Investigating Quality of Urban Life

by Robert J. Stimson Robert W. Marans

The study of quality of urban life involves both an objective approach to analysis using spatially aggregated secondary data and a subjective approach using unit record survey data whereby people provide subjective evaluations of QOL domains. This book provides a comprehensive overview of theoretical perspectives on QOUL and methodological approaches to research design to investigate QOUL and measure QOL dimensions. It incorporates empirical investigations into QOUL in a range of cities across the world.

‘In Considerable Variety’: Introducing The Diversity Of Australia's Insects

by Tim R. New

The book introduces basic entomology, emphasising perspectives on insect diversity important in conservation assessment and setting priorities for management, as a foundation for managers and others without entomological training or background. It bridges the gap between photographic essays on insect identification and more technical texts, to illustrate and discuss many aspects of taxonomic, ecological and evolutionary diversity in the Australian insect fauna, and its impacts in human life, through outlines of many aspects of insect natural history.

Nanotechnology, the Brain, and the Future

by Jason Scott Robert Sean A. Hays Clark A. Miller Ira Bennett

Our brain is the source of everything that makes us human: language, creativity, rationality, emotion, communication, culture, politics. The neurosciences have given us, in recent decades, fundamental new insights into how the brain works and what that means for how we see ourselves as individuals and as communities. Now - with the help of new advances in nanotechnology - brain science proposes to go further: to study its molecular foundations, to repair brain functions, to create mind-machine interfaces, and to enhance human mental capacities in radical ways. This book explores the convergence of these two revolutionary scientific fields and the implications of this convergence for the future of human societies. In the process, the book offers a significant new approach to technology assessment, one which operates in real-time, alongside the innovation process, to inform the ways in which new fields of science and technology emerge in, get shaped by, and help shape human societies.

Common Infectious Diseases of Insects in Culture: Diagnostic and Prophylactic Methods (SpringerBriefs in Animal Sciences)

by Jose Marcelino Svetlana Gouli Vladimir Gouli

This handbook gives a comprehensive and copious illustrated description, with original art work, of the most common diseases in laboratory reared insect colonies, comprising Viruses (Baculoviridae, Reoviridae, Poxviridae, Iridoviridae); Bacteria (Bacillaceae, Pseudomonadaceae, Enterobacteriaceae); Rickettsia; Fungi and Microsporidia and Protozoa. Gregarine and Coccidian parasitoids are also depicted. Manuals for the diagnostic of insect diseases have been published in the 90's, however, these were intended for professional insect pathologists or for proficient training in invertebrate pathology, hence requiring some scientific background in insect pathology. Currently, most guides are web based, not comprehensive and solely addressing the most common diseases in a particular insect, or group of insects, reared in laboratory facilities. A comprehensive and proficient practical handbook for students and technicians working with insect reared colonies is lacking in the current literature.

Pollination Biology

by Dharam P. Abrol

This book has a wider approach not strictly focused on crop production compared to other books that are strictly oriented towards bees, but has a generalist approach to pollination biology. It also highlights relationships between introduced and wild pollinators and consequences of such introductions on communities of wild pollinating insects. The chapters on biochemical basis of plant-pollination interaction, pollination energetics, climate change and pollinators and pollinators as bioindicators of ecosystem functioning provide a base for future insights into pollination biology. The role of honeybees and wild bees on crop pollination, value of bee pollination, planned honeybee pollination, non-bee pollinators, safety of pollinators, pollination in cages, pollination for hybrid seed production, the problem of diseases, genetically modified plants and bees, the role of bees in improving food security and livelihoods, capacity building and awareness for pollinators are also discussed.

Philosophy of Behavioral Biology

by Kathryn S. Plaisance Thomas A.C. Reydon

This volume provides a broad overview of issues in the philosophy of behavioral biology, covering four main themes: genetic, developmental, evolutionary, and neurobiological explanations of behavior. It is both interdisciplinary and empirically informed in its approach, addressing philosophical issues that arise from recent scientific findings in biological research on human and non-human animal behavior. Accordingly, it includes papers by professional philosophers and philosophers of science, as well as practicing scientists. Much of the work in this volume builds on presentations given at the international conference, "Biological Explanations of Behavior: Philosophical Perspectives", held in 2008 at the Leibniz Universität Hannover in Germany. The volume is intended to be of interest to a broad range of audiences, which includes philosophers (e.g., philosophers of mind, philosophers of biology, and metaethicists), as well as practicing scientists, such as biologists or psychologists whose interests relate to biological explanations of behavior.

The Sirex Woodwasp and its Fungal Symbiont:

by Bernard Slippers Peter De Groot Michael John Wingfield

The Sirex woodwasp, Sirex noctilio, is the most important invasive alien insect pest of Pinus plantations in the Southern Hemisphere. It now also threatens pines in North America. This book brings together the worldwide knowledge of researchers from Universities and Government institutions, as well as forest industry practitioners that have worked on the pest. Importantly, it is the first comprehensive treatment of the subject since S. noctilio was discovered outside its native range around 1900. The book covers all aspects of the biology and management of S. noctilio, including aspects of the insects' taxonomy, general life history, host-plant relationships, population dynamics, chemical ecology and symbiosis with the fungus Amylostereum areolatum. The book also contains a comprehensive synthesis of the history and current status of the pest and worldwide efforts to control it, including biological control, silviculture and quarantine.

Reef Fish Spawning Aggregations: Biology, Research and Management

by Patrick L. Colin Yvonne Sadovy de Mitcheson

Reef fish spawning aggregations, ranging from small groups to many tens of thousands of individuals, are spectacular but poorly known natural phenomena whereby fish assemble at specific times and locations to spawn. For some species these large groups may be the only form of reproduction, the high fish numbers briefly giving a false impression of stability and abundance--an 'illusion of plenty'. They are often a focus for intensive seasonal fishing because of their predictability and because many important commercial fishes form them. Highly vulnerable to overexploitation, many aggregations and their associated fisheries, have disappeared or are in decline. Few are effectively managed or incorporated into protected areas. Aggregations are not well understood by fishery scientists, managers and conservationists and their significance little appreciated by fishers or the wider public. To ensure their persistence to replenish important fisheries in coral ecosystems, maintain their ecosystem function and continue to delight divers, a significant change in perspective is needed to foster protection and management. This book provides comprehensive and practical coverage of the biology, study and management of reef fish aggregations, exploring their how, when, where, and why. It explores ways to better protect, study, manage and conserve them, while identifying key data gaps and questions. The text is extensively illustrated with many unique, never before published, photographs and graphics. Case studies on over 20 interesting and important fishes are included, outlining their biology and fisheries and highlighting major concerns and challenges.

Acquired Mitochondropathy – A New Paradigm in Western Medicine explaining Chronic Diseases

by Enno Freye

The book on Acquired Mitochondropathy offers a new perspective on the understanding and the treatment of chronic ailments. Addressing a new paradigm deemed necessary, since in one of every four adults in the western world chronic ailments are on the rise. Resulting from energy dysfunction of cellular organelles, the mitochondria, the most of the common symptoms the physician faces during medical consultation are presented. An increasing focus on chronic disabilities presents difficulties for the busy practitioner, since patients typically describe a complex pattern of discomfort, disability, and distress, with pain affecting physical, social, and psychological functioning, which have to be put in the proper perspective. Since clinicians must efficiently condense widely varied symptomatic descriptions into characteristic patterns to permit accurate diagnosis and implement effective treatment, this book serves as a useful educational resource for the healthcare provider.

It is a "Festschrift" for the 70th birthday of Randolf Menzel, who devoted his life to the topic of the book. The book will include an open commentary for each section written by Randolf Menzel, and discussed with the authors. The written contributions take their inspiration from a symposium on the topic, with all the authors, that was held in Berlin in summer 2010

Regulation of Agricultural Biotechnology: The United States and Canada

by Chris A. Wozniak Alan Mchughen

Agricultural biotechnology takes many forms and applications, with the number and diversity of products ever increasing. With this rapid development, regulatory authorities have sought to keep pace through regulatory adjustments and advances to ensure the safe and beneficial use of this critical technology. The regulatory systems for the U.S. and Canada are not static and must evolve in order to maintain relevance, efficiency and applicability to the challenges encountered. The diverse authors, drawn from the biotechnology industry, academia, government research and regulatory agencies, offer their perspectives of the historical and current system and suggest where it can be improved in the future. Based upon vast experience interacting with the regulatory system, the editors and authors offer demystifying views of the US and Canadian regulatory structures and how they came to be. We know of no other effort to present the biotechnology regulatory systems of the US and Canada in an open forum which will benefit those in the regulated community as well as those charged with oversight of the products of biotechnology, and ultimately the consumer!

The Acheulian Site of Gesher Benot Ya‘aqov Volume III

by Lutz Kindler Naama Goren-Inbar Rivka Rabinovich Sabine Gaudzinski-Windheuser

Multidisciplinary research on the Early-Middle Pleistocene site of Gesher Benot Ya'aqov has yielded abundant climatic, environmental, ecological and behavioral records. The 15 archaeological horizons form a sequence of Acheulian occupational episodes on the shore of the paleo-Lake Hula. These enable us to reconstruct numerous aspects of the survival and adaptation of ancient hominins, leading to a better understanding of their evolution and behavior. This book presents the faunal analyses of medium-sized and large mammals, providing taxonomic, taphonomic and actualistic data for the largest faunal assemblages. The study of modes of animal exploitation reveals valuable information on hominin behavior.

by Jed Z. Buchwald

New essays in science history ranging across the entire field and related in most instance to the works of Charles Gillispie, one of the field's founders.

The Biotechnology Debate

by Bernice Bovenkerk

This book grounds deliberative democratic theory in a more refined understanding of deliberative practice, in particular when dealing with intractable moral disagreement regarding novel technologies. While there is an ongoing, vibrant debate about the theoretical merits of deliberative democracy on the one hand, and more recently, empirical studies of specific deliberative exercises have been carried out, these two discussions fail to speak to one another. Debates about animal and plant biotechnology are examined as a paradigmatic case for intractable disagreement in today's pluralistic societies. This examination reveals that the disagreements in this debate are multi-faceted and multi-dimensional and can often be traced to fundamental disagreements about values or worldviews. "One of the acute insights to emerge from this examination is that deliberation can serve different purposes vis-à-vis different types of problem. In the case of deeply unstructured problems, like the modern biotechnology debate, the aim of inclusion is more appropriate than the aim of consensus. This book highlights the importance of political culture and broader institutional settings in shaping the capacity and propensity of citizens to engage in deliberation and the degree to which governments are prepared to relinquish authority to deliberative mini-publics."

Non-fibrillar Amyloidogenic Protein Assemblies - Common Cytotoxins Underlying Degenerative Diseases

by Gal Bitan Farid Rahimi

Amyloid-forming proteins are implicated in over 30 human diseases. The proteins involved in each disease have unrelated sequences and dissimilar native structures, but they all undergo conformational alterations to form fibrillar polymers. The fibrillar assemblies accumulate progressively into disease-specific lesions in vivo. Substantial evidence suggests these lesions are the end state of aberrant protein folding whereas the actual disease-causing culprits likely are soluble, non-fibrillar assemblies preceding the aggregates. The non-fibrillar protein assemblies range from small, low-order oligomers to spherical, annular, and protofibrillar species. Oligomeric species are believed to mediate various pathogenic mechanisms that lead to cellular dysfunction, cytotoxicity, and cell loss, eventuating in disease-specific degeneration and systemic morbidity. The particular pathologies thus are determined by the afflicted cell types, organs, systems, and the proteins involved. Evidence suggests that the oligomeric species may share structural features and possibly common mechanisms of action. In many cases, the structure-function interrelationships amongst the various protein assemblies described in vitro are still elusive. Deciphering these intricate structure-function correlations will help understanding a complex array of pathogenic mechanisms, some of which may be common across different diseases albeit affecting different cell types and systems.

Stem Cells and Human Diseases

by Rakesh K. Srivastava Sharmila Shankar

The main objective of this book is to provide a comprehensive review on stem cells and their role in tissue regeneration, homeostasis and therapy. In addition, the role of cancer stem cells in cancer initiation, progression and drug resistance are discussed. The cell signaling pathways and microRNA regulating stem cell self-renewal, tissue homeostasis and drug resistance are also mentioned. Overall, these reviews will provide a new understanding of the influence of stem cells in tissue regeneration, disease regulation, therapy and drug resistance in several human diseases.

The Biology of Subcellular Nitric Oxide

by Tamás Rőszer

This book fills in a gap in the NO literature. Recent progress in the field of NO-biology shows that NO is generated within distinct cell compartments, including specific plasma membrane regions, mitochondria, chloroplasts, peroxisomes, the Golgi-complex and intracellular membrane systems. NO synthesis plays specific roles in these compartments and, in turn, cell organelles also control intracellular NO levels. This monograph focuses on the roles played by the subcellular NO-signaling microdomains in the prokaryote-, fungus-, plant- and animal cells and shows how NO behaves as an intracellular signal in distinct cellular environments. This monograph also provides a summary of our knowledge on how NO synthesis came through evolution to be associated with organelles and subcellular compartments. Promotes the novel ideas that some functions of NO and its associations with subcellular units have been conserved during the evolution of the cell. A special chapter is dedicated to the biomedical relevance of subcellular NO synthesis, and this chapter also discusses the evidence that altered compartmentalization of NO-producing enzymes causes disease.

Insect Conservation: Past, Present and Prospects

by Tim R. New

The history of interest and practice in insect conservation is summarised and traced through contributions from many of the leaders in the discipline, to provide the first broad global account of how insects have become incorporated into considerations of conservation. The essays collectively cover the genesis and development of insect conservation, emphasising its strong foundation within the northern temperate regions and the contrasts with much of the rest of the world. Major present-day scenarios are discussed, together with possible developments and priorities in insect conservation for the future.

Evolutionary Psychology and the Propositional-attitudes

by Alex Walter

The two essays provide a critical examination of theory and research in the field of evolutionary psychology. The view advanced here is that philosophical materialism and minimalist assumptions about adaptation serve Darwinian psychology better than the more popular alternative view that relies on cognitive dualism and propositional-attitude psychology to formulate evolutionary psychology theory. A commitment to cognitive dualism is destined to undermine the physical basis of behavior upon which evolutionary theory depends. Many evolutionary psychologists do not see this but are seduced by the easy way in which hypotheses can be formulated using the 'propositional-attitude' model. The challenge is to develop a materialistic and mechanistic approach to understanding human cognition and behavior, including linguistic and social behavior.
