Insect Biodiversity Functional Dynamics And Ecological Perspectives

Rapid depletion and degradation of species in diverse ecosystems and the implications of this for human welfare have the cause for increasing concern. Biodiversity or variability among living organisms and the ecological complexes of which they are a part, is essential for ensuring the basic ecological services and resources necessary for sustaining human welfare. The loss of biodiversity is therefore, considered one of the most serious problem threatening the world today. An understanding of the ecological implications of the increasing loss of bodiversity, not to mention of the economic implications, has therefore, became vital. A biodiversity loss is irreversible. A calls for increased caution in our efforts to convert and exploit natural resources. Some minimal level of biodiversity is necessary to main ecological functioning, which in turn is necessary for generating the biological resources on which human welfare depends. Needless to emphasive that substantial biodiversity loss occurs due to forest clearing and degradation, leading to the need for assessing biodiversity in different ecosystems. Keeping these aspects in mind, the present volume highlights biodiversity in different cropping systems besides that the impact of cold and hot deserts. Selection of the topics in the various chapters is essentially because of the experience of the authors in the field of biodiversity.

Despite acknowledgment that loss of living diversity is an international biological crisis, the ecological causes and consequences of extinction have not yet been widely addressed. In honor of Edward O. Wilson, winner of the 1993 International Prize for Biology, an international group of distinguished biologists bring ecological, evolutionary, and management perspectives to the issue of biodiversity. The roles of ecosystem processes, community structure and population dynamics are considered in this book. The goal, as Wilson writes in his introduction, is "to assemble concepts that unite the disciplines of systematics and ecology, and in so doing to create a sound scientific basis for the future management of biodiversity."

The dominance of insects amongst all living organisms on earth, coupled with infinite wealth of knowledge so important for our own existence, is a fundamental scientific fact which is yet to be widely acknowledged. This dominance means that in numbers of species beyond our comprehension these animals permeate diverse and essential natural processes in Earth's terrestrial, aerial and freshwater ecosystems, contributing to the function of the natural world as a self-sustaining biological system. Invariably insects are an integral and complex part of the terrestrial and freshwater ecosystems with which the future of humans is inextricably linked. Insects have ultimately achieved a formidable diversity. Generally, insects are beneficial organisms, however, many of them are important pests and/or vectors to a large number of parasites and other microbial pathogens to both human being, his associates and the plants. The burden caused by their infestation or infection run up to several million-zillion rupees annually. Therefore, knowledge about extreme biodiversity and ecological relationships of these animals is a practical necessity: in the man's own interest to sustain the species. Packed with original 25 original articles/reviews, this book on 'Entomology: Ecology and Biodiversity' offers an invaluable opportunity to comprehend more deeply about our most intimate allies - the insects! The book truly establishes a foundation in basic entomology through varied and diverse treatment to entomology, while focusing on specialized topics in insect ecology and biodiversity, forensic and medical entomology.

Volume Two of the new guide to the study of biodiversity in insects Volume Two of Insect Biodiversity: Science and Society presents an entirely new, companion volume of a comprehensive resource for the most current research on the influence insects have on humankind and on our endangered environment. With contributions from leading researchers and scholars on the topic, the text explores relevant topics including biodiversity in different habitats and regions, taxonomic groups, and perspectives. Volume Two offers coverage of insect biodiversity in regional settings, such as the Arctic and Asia, and in particular habitats including crops, caves, and islands. The authors also include information on historical, cultural, technical, and climatic perspectives of insect biodiversity. This book explores the wide variety of insect species and their evolutionary relationships. Case studies offer assessments on how insect biodiversity can help meet the needs of a rapidly expanding human population, and examine the consequences that an increased loss of insect species will have on the world. This important text: Offers the most up-to-date information on the important topic of insect biodiversity Explores vital topics such as the impact on insect biodiversity through habitat loss and degradation and climate change With its companion Volume I, presents current information on the biodiversity of all insect orders Contains reviews of insect biodiversity in culture and art, in the fossil record, and in agricultural systems Includes scientific approaches and methods for the study of insect biodiversity The book offers scientists, academics, professionals, and students a guide for a better understanding of the biology and ecology of insects, highlighting the need to sustainably manage ecosystems in an ever-changing global environment.

This book aims at an understanding of diverse mutualistic interactions, with all individuals tending to display their own adaptational ranges. In view of different species using different kinds of microhabitats, the diversity of assemblages goes a long way towards a better appreciation of the adaptive trends of the species involved therein. Insect assemblages and communities are shaped by the compositional, structural and trophic interactions which hold together ecological communities.

The topic of the book is covered at the cellular, tissue, organ and organism levels and inputs from all these hierarchical levels of plant organization have been carefully integrated to get a holistic picture of growth and development in plants. The book will be useful to undergraduate, post-graduate and research students, and teachers of botany/plant sciences, plant biotechnology, agriculture and forestry.

Insects are a dominant component of biodiversity in terrestrial ecosystems and play a key role in mediating the relationship between plants and ecosystem processes. This volume examines their effects on ecosystem functioning, focusing mainly, but not exclusively, on herbivorous insects. Renowned authors with extensive experience in the field of plant-insect interactions, contribute to the volume using examples from their own work.

Insect Ecology is the world's foremost reference to the never-ending and crucial interactions of the richest taxon of organisms on this earth, with perhaps some 8 million extant species. Now in its Third Edition and twentieth year of publication, Insect Ecology has endured as an unparalleled classic. Taking the reader from an explanation of the science to its significance as a discipline, Insect Ecology is a meticulous, systematic examination of the underlying dynamics of plant-insect interactions, predation, parasites and hosts, and mutualistic relationships, including pollination ecology, that are central to understanding the insects' role in nature. Viewing the largely invisible drama of natural protagonists and antagonists, hidden in the lush foliage of a tropical rain forest or temperate woody vegetation, Peter Price details the unique traits, behaviors, and functions of insects, while placing them in the broader contexts of their places in food webs, ecosystem function, population dynamics, and community interactions. The author also describes the various levels of insect interaction, from trophic relationships (Part II), populations (Part III), and communities (Part IV), while unfolding the infinite variety of insect species and their visible legacy in the fossil record. Full of fascinating details ("Ants are everywhere, but only occasionally noticed. They run much of the terrestrial world as the premier soil turners." "[Insect] galls provide tanning acids and the basis for inks."), Insect Ecology offers detail and breadth, while providing timely discussion on the conservation of biodiversity, the existence and study of vacant ecological niches, latitudinal gradients in species richness, and evolutionary perspectives on population dynamics. The book also examines the development of theory in insect ecology and how it is advanced. Novel features in the Third Edition include four new chapters, covering the importance of insect ecology, the development of theory in the science, hypotheses on plant and herbivore interactions, and a synthesis chapter on population dynamics. Subheadings within chapters provide easier subject access, and many new figures contribute to the book's aesthetic appeal. Clearly organized and with a bibliography of 2,000 references to up-to-date and classic literature, the Third Edition of Insect Ecology is a practical, well-formatted resource. Also copiously illustrated with over 350 figures, many new to this edition, Insect Ecology is a lush graphic tour of the minute, often startling universe of insects in their native habitat. With a history in geologic time much older than the terrestrial vertebrates, insects speak to us-the scarab beetle encased in amber, or New Zealand's endangered large Wellington speargrass weevil-of a resilience and ingenuity oddly reflective of our own. Insect Ecology has let generations of agriculturalists, ecologists, entomologists, environmental scientists, foresters, professionals, and students understand the insects' world, and ours. With unerring detail and breadth, Insect Ecology has described for generations of professionals the interactions and dynamics of the world's richest group of species-the insects-whose wildly various 8 million forms have been the source of endless fascination and study. From caterpillars to the goliath beetle, from the adult copper butterfly to the agromyzid fly, the insect universe is at once ordinary and exotic, capturing, in microcosm, nature's complexity and beauty.
