Available in PDF, EPUB and Kindle. Book excerpt: Conifers--pine, fir, and spruce trees--are dominant species in forests around the world. This book focuses on the physiology of conifers and how these physiological systems operate. Special consideration is devoted to the means by which ecophysiological processes influence organismal function and distribution. Chapters focus on the genetics of conifers, their geographic distribution and the factors that influence this distribution, the impact of insect herbivory on ecophysiological parameters, the effects of air pollution, and the potential impact that global climatic changes will have upon conifers. Because of the growing realization that forests have a crucial role to play in global environmental health, this book will appeal to a developing union of ecologists, physiologists and more theoretically minded foresters.

Available in PDF, EPUB and Kindle. Book excerpt: The second edition of Ecological Forest Management Handbook continues to provide forestry professionals and students with basic principles of ecological forest management and their applications at regional and site-specific levels. Thoroughly updated and revised, the handbook addresses numerous topics and explains that ecological forest management is a complex process that requires broad ecological knowledge. It discusses how to develop adaptive management scenarios to harvest resources in a sustainable way and provide ecosystem services and social functions. It includes new studies on ecological indicators, the carbon cycle, and ecosystem simulation models for various forest types: boreal, temperate, and tropical forests. NEW IN THE SECOND EDITION Provides a comprehensive collection of sustainable forest management principles and their applications Covers new ecological indicators that can be applied to address forest environmental issues Includes all types of models: empirical, gap, and process-based models Explains several basic ecological and management concepts in a clear, easy-to- understand manner This handbook is intended for researchers, academics, professionals, and undergraduate and graduate students studying and/or involved in the management of forest ecosystems.

Download or read book Insect Ecology written by Timothy D. Schowalter and published by Academic Press. This book was released on 2016-07-29 with total page 776 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insect Ecology: An Ecosystem Approach, Fourth Edition, follows a hierarchical organization that begins with relatively easy-to-understand chapters on adaptive responses of insect populations to various environmental changes, disturbances, and anthropogenic activities, how insects find food and habitat resources, and how insects allocate available energy and nutrients. Chapters build on fundamental information to show how insect populations respond to changing environmental conditions, including spatial and temporal distribution of food and habitat. The next section integrates populations of interacting species within communities and how these interactions determine structure of communities over time and space. Other works in insect ecology stop there, essentially limiting presentation of insect ecology to evolutionary responses of insects to their environment, including the activities of other species. The unique aspect of this book is its four chapters on ecosystem structure and function, and how herbivores, pollinators, seed predators, and detritivores drive ecosystem dynamics and contribute to ecosystem stability. - Provides the most advanced synthesis of insect ecology, with updated material throughout and new chapters - Presents the roles of insects in delivery of ecosystem services and applications to pest management and conservation - Features full coverage of ecosystem structure and function balanced with essential background on evolutionary aspects - Includes case studies highlighting practical and theoretical applications for topics covered in each chapter

Available in PDF, EPUB and Kindle. Book excerpt: Forest landscape disturbances are a global phenomenon. Simulation models are an important tool in understanding these broad scale processes and exploring their effects on forest ecosystems. This book contains a collection of insights from a group of ecologists who address a variety of processes: physical disturbances such as drought, wind, and fire; biological disturbances such as defoliating insects and bark beetles; anthropogenic influences; interactions among disturbances; effects of climate change on disturbances; and the recovery of forest landscapes from disturbances—all from a simulation modeling perspective. These discussions and examples offer a broad synopsis of the state of this rapidly evolving subject.
Download or read book Insects and Sustainability of Ecosystem Services written by Timothy D. Schowalter and published by CRC Press. This book was released on 2013-05-23 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: With few exceptions, insects are perceived in industrialized countries as undesirable pests. In reality, relatively few insects interfere with us or our resources. Most have benign or positive effects on ecosystem services, and many represent useful resources in non-industrialized countries. Challenging traditional perceptions of the value of insects, Insects and Sustainability of Ecosystem Services explores the ways insects affect the ecosystem services we depend upon. It also fosters an appreciation for the amazing diversity, adaptive ability, and natural roles of insects. The book discusses how the ways in which we manage insects will determine an ecosystem’s capacity to continue to supply services. It reviews aspects of insect physiology, behavior, and ecology that affect their interactions with other ecosystem components and ecosystem services, emphasizing critical effects of insects on the sustainability of ecosystem processes and services. The author examines the integration of insect ecology with self-regulatory aspects of ecosystems that control primary production, energy and nutrient fluxes, and global climate—functions that underlie the sustainability of ecosystem services. Clearly, we need environmental policies that meet needs for pest control where warranted, but do not undermine the important contributions of insects to sustaining ecosystem processes and services. With in-depth coverage of the multiple, often compensatory, effects of insects on various resources or ecosystem services and on the consequences of control tactics for those resources or services, Insects and Sustainability of Ecosystem Services recommends changes in perspectives and policies regarding insects that will contribute to sustainability of ecosystem services.

Available in PDF, EPUB and Kindle. Book excerpt: The future of the world's forests is at the forefront of environmental debate. Rising concerns over the effects of deforestation and climate change are highlighting the need both to conserve and manage existing forests and woodland through sustainable forestry practices. The Forests Handbook, written by an international team of both scientists and practitioners, presents an integrated approach to forests and forestry, applying our present understanding of forest science to management practices, as a basis for achieving sustainability. Volume One presents an overview of the world's forests; their locations and what they are like, the science of how they operate as complex ecosystems and how they interact with their environment. Volume Two applies this science to reality; it focuses on forestry interventions and their impact, the principles governing how to protect forests and on how we can better harness the enormous benefits forests offer. Case studies are drawn from several different countries and are used to illustrate the key points. Development specialists, forest managers and those involved with land and land-use will find this handbook a valuable and comprehensive overview of forest science and forestry practice. Researchers and students of forestry, biology, ecology and geography will find it equally accessible and useful.
