Insects And Ecosystem Function

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.

In the past two decades, an increasing number of ecologists have started to investigate the importance of biodiversity for ecological processes such as energy flow and nutrient cycling, often referred to as 'ecosystem functioning'. 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 is the first to summarize 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. In addition to providing concise reviews of the field, this volume discusses in detail the advantages and disadvantages of various techniques of manipulating insect herbivory. Thus, the text provides both a theoretical basis as well as practical advice for future manipulative studies of biodiversity-ecosystem functioning.

CHOICE Highly Recommended title, 2022! Forest insects play important roles ecologically and economically. They pollinate plants, decompose dead plant and animal tissue, provide food for vertebrates, regulate pest organisms and shape entire landscapes. Some are considered pests, while others provide usable products. Introduced species may become invasive, while the survival of others is threatened. Forest Insects in Europe: Diversity, Functions and Importance has been written not only with professional entomologists in mind, but also for nature lovers generally. The descriptions of the various roles insects play in forest ecosystems are intended to be easily comprehensible, but still scientific. The book is richly illustrated with attractive photos and contains 580 fascinating colour images of more than 300 different insect and spider species. The German edition was awarded the Prix Moulines by the Swiss Entomological Society in 2019.

This new innovative work on insects and their impact on the ecosystem covers the role of insects in environmental pollution, their use in sustainable agricultural services, and the industrial, forensic, and medical applications of insects and their pure products. The book also covers the entomological and molecular aspects of insects, identifies the gaps in the research, and looks at integrated management strategies for pests. Volume 1: Importance, Threats, Conservation, and Economic Perspectives, reviews the different insect orders regarding their diversity and importance in providing free ecological services and discusses the diversity patterns of world biogeographic zones and how insects contribute to maintaining ecological diversity. Volume 2: Environmental Indicators, Molecular Approaches, and Management Strategies discusses the role of insects as environmental indicators, the effect of pesticides on insect diversity, strategies to control the diversity of insects, medical and forensic importance of insects, exploring new insect species through DNA barcoding, integrated pest management, the role of insect population in agriculture, and eco-friendly pest management approaches. Some topics covered in the book include: Role of insects for the sustainable agricultural development Commercial importance of insects and their products Food additive roles of insects and formulation of remedies for the reduction of disease pathogenesis Management strategies for pest control Some specific topics include colony collapse disorder of managed honey bee (Apis mellifera l.) populations, insects as strong crime indicator tools in forensic sciences, insect-based value-added products, and more. Together, these two volumes offer important information for researchers, academicians, scientists, industrialists, teachers, entomologists, and students for understanding the contribution of insects towards the sustainability of the ecosystem.

The term biodiversity has become a mainstream concept that can be found in any newspaper at any given time. Concerns on biodiversity protection are usually linked to species protection and extinction risks for iconic species, such as whales, pandas and so on. However, conserving biodiversity has much deeper implications than preserving a few (although important) species. Biodiversity in ecosystems is tightly linked to ecosystem functions such as biomass production, organic matter decomposition, ecosystem resilience, and others. Many of these ecological processes are also directly implied in services that the humankind obtains from ecosystems. The first part of this book will introduce different concepts and theories important to understand the links between ecosystem function and ecosystem biodiversity. The second part of the book provides a wide range of different studies showcasing the evidence and practical implications of such relationships.

The biota of the earth is being altered at an unprecedented rate. We are witnessing wholesale exchanges of organisms among geographic areas that were once totally biologically isolated. We are seeing massive changes in landscape use that are creating even more abundant succes sional patches, reductions in population sizes, and in the worst cases, losses of species. There are many reasons for concern about these trends. One is that we unfortunately do not know in detail the conse quences of these massive alterations in terms of how the biosphere as a whole operates or even, for that matter, the functioning of localized ecosystems. We do know that the biosphere interacts strongly with the atmospheric composition, contributing to potential climate change. We also know that changes in vegetative cover greatly influence the hydrology and biochemistry ofa site or region. Our knowledge is weak in important details, however. How are the many services that ecosystems provide to humanity altered by modifications of ecosystem composition? Stated in another way, what is the role of individual species in ecosystem function? We are observing the selective as well as wholesale alteration in the composition of ecosystems. Do these alterations matter in respect to how ecosystems operate and provide services? This book represents the initial probing of this central ques tion. It will be followed by other volumes in this series examining in depth the functional role of biodiversity in various ecosystems of the world.

This handbook outlines the main methods and techniques, both modern and traditional, used to measure insect diversity. With the growing relevance of insect conservation in nature, this guide should assist students in understanding a complicated field.
