  • An Ecosystem Approach provides a modern perspective of insect ecology that integrates two approaches traditionally used to study insect ecology: evolutionary and ecosystem. This integration substantially broadens the scope of insect ecology and contributes to prediction and resolution of the effects of current environmental changes, as these affect and are affected by insects. The third edition includes an updated and expanded synthesis of feedback and interactions between insects and their environment.

  • Looking up ‘‘aquatic food web’’ on Google provides a dizzying array of eclectic sites and information (and disinformation!) to choose from. However, even within this morass it is clear that aquatic food-web research has expanded greatly over the last couple of decades, and includes a wide array of studies from both theoretical and empirical perspectives. This book attempts to bring together and synthesize some of the most recent perspectives on aquatic food-web research, with a particular emphasis on integrating that knowledge within an ecosystem framework....

  • Ecological issues and environmental problems have become exceedingly complex. Today, it is hubris to suppose that any single discipline can provide all the solutions for protecting and restoring ecological integrity. We have entered an age where professional humility is the only operational means for approaching environmental understanding and prediction.

  • SECTION I ECOLOGY OF INDIVIDUAL INSECTS THE INDIVIDUAL ORGANISM IS A FUNDAMENTAL unit of ecology. Organisms interact with their environment and affect ecosystem processes largely through their cumulative physiological and behavioral responses to environmental variation. Individual success in finding and using necessary habitats and resources to gain reproductive advantage determines fitness.

  • The idea for this book stems from a meeting sponsored by the European Union, organized by N. van Breemen, and held in Doorweerth at the end of 1991. At this meeting a large number of European scientists discussed the different issues related to the accumulation and decomposition of organic matter in terrestrial ecosystems. One of the objectives was to gather scientists from various disciplines (biologists, chemists, ecologists, agriculturalists) to pool their different disciplinary approaches and come up with a common perspective for future research on soil organic matter.

  • 12 Herbivory HERBIVORY IS THE RATE OF CONSUMPTION BY ANIMALS OF ANY PLANT parts, including foliage, stems, roots, flowers, fruits, or seeds. Direct effects of insects on plant reproductive parts are addressed in Chapter 13. Herbivory is a key ecosystem process that reduces density of plants or plant materials.

  • Urban ecology in Berlin has been developing over the past 350 years, from garden floras and wild floras of castles and ruins to the Graduate Research Training Group 780 “Perspectives in Urban Ecology”. This program has brought together universities and scientific institutes from all over Berlin. Since the beginning, urban ecology in Berlin has included approaches from biology and geography, leading to the current interdisciplinary work documented in this summarizing publication.

  • The focus of the MA is on ecosystem services (the benefits people obtain from ecosystems), how changes in ecosystem services have affected human well-being in the past, and what role these changes could play in the present as well as in the future. The MA is an assessment of responses that are available to improve ecosystem management and can thereby contribute to the various constituents of human well-being. The specific issues addressed have been defined through consultation with the MA users.

  • SECTION V SYNTHESIS THE PREVIOUS FOUR SECTIONS HAVE ADDRESSED insect ecology at the individual, population, community, and ecosystem levels of organization. Resource acquisition and allocation by individuals (Section I) can be seen to depend on population (Section II), community (Section III), and ecosystem (Section IV) conditions that the individual also influences.

  • Emission inventories play a dual role in global air pollution issues. Firstly, they can be used directly to establish the more important source categories, to identify trends in emissions and to examine the impact of different policy approaches. Secondly, emission inventories are used to drive atmospheric models applied to assess the environmental consequences of changing trace gas emissions and concentrations and to provide advice to policy makers. This second role contributes to the atmospheric modelling community being an important user of emission inventories.

  • Over the past 25 years the discipline of ecotoxicology has undergone two major developments. Firstly, new assays have been developed, deploying organisms that bear added relevance to the specific environment under investigation. Several new procedures assess the effects on organisms after exposure to environmental samples rather than to spiked water or sediment samples. Also noteworthy is the considerable attention given to effects of chronic exposure to low levels of contaminants.

  • This volume, edited by John Gunn, Rob Steedman, and Dick Ryder, pulls together an incredibly broad mix of people and topics under a single cover. As such, it is a worthy addition to the new series from CRC Press — Integrative Studies in Water Management and Land Development — that was initiated in 2002 with publication of my own edited volume, Handbook of Water Sensitive Planning and Design . Books like these are rare, but they shouldn’t be.

  • Urban Ecology is the study of ecosystems that include humans living in cities and urbanizing landscapes. It is an emerging, interdisciplinary field that aims to understand how human and ecological processes can coexist in human-dominated systems and help societies with their efforts to become more sustainable. It has deep roots in many disciplines including sociology, geography, urban planning, landscape architecture, engineering, economics, anthropology, climatology, public health, and ecology.
