  • The impetus to write a book on the riverine ecosystem synthesis emerged at the 2005 annual meeting of the North American Benthological Society in New Orleans, and barely 2 months later, we signed a contract with Academic Press. This book was to be an expansion of a manuscript that was In Press at that time in River Research and Applications (Thorp et al., 2006).

  • The purpose of this collection is to present some of the diversity of ideas and studies about species that can be classifi ed as “ecosystem engineers.” As with any developing concept, we fi nd disagreement about the meaning and usefulness of this term in the literature and among ourselves. The idea for the book arose in a National Center for Ecological Analysis and Synthesis (NCEAS) working group designed to develop models of ecosystem engineering species.

  • This report is in response to a request from the Exxon Valdez Oil Spill Trustee Council to review the Gulf of Alaska Ecosystem Monitoring and Research Program (GEM). To ensure that the GEM program is based on a science plan that is robust, far-reaching, and scientifically sound, the Trustee Council asked the National Academies to serve as an independent advisor. The Academies appointed a special committee and charged it to review the scope and content of the program as it evolved.

  • 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.

  • T his second edition provides an updated and expanded synthesis of feedbacks and interactions between insects and their environment. A number of recent studies have advanced understanding of feedbacks or provided useful examples of principles. Molecular methods have provided new tools for addressing dispersal and interactions among organisms and have clarified mechanisms of feedback between insect effects.

  • Land management is presently undergoing enormous change: away from managing single resources to managing ecosystems. From forest to tundra, to desert, to steppe, the world’s ecosystems vary vastly. To manage them effectively we need to understand their geographic distribution better. We need to do this at various levels of detail because ecosystems exist at multiple scales in a hierarchy, from regional to local. Maps are needed to display ecosystem distribution and hierarchy. Until now, information on defining ecosystem boundaries has been scarce.

  • The Pacific Ocean isn’t just the deepest and largest ocean. It is also home to one of the world’s most amazing natural wonders: the Great Barrier Reef. Located off of the northeastern coast of Australia, the Great Barrier Reef is 210 separate coral reefs that stretch for more than 1,260 miles (2,028 kilometers) around northern Australia. Th e Great Barrier Reef is full of some of the most amazing, beautiful, and deadly sea creatures on the planet, including the Irukandji jellyfi sh and the great white shark....

  • 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.

  • From February 11 to 13, 2001, at the Lodge at Snowbird ski resort in the Wasatch Mountains of Utah, 17 people met to talk, ski, relax, and try to find common ground. What emerged was the Agile Software Development movement. Representatives from Extreme Programming (XP), Scrum, the Dynamic Systems Development Method (DSDM), Adaptive Software Development (ASD), Crystal Methods, Feature-Driven Development (FDD), Pragmatic Programming, and others sympathetic to the need for an alternative to document-driven, rigorous software development processes convened....

  • The Earth’s polar regions (see Figure 1.1) are ecologically, economically, and, increasingly, geopolitically important; they are particularly vulnerable to the speed and magnitude of climate change and have significant potential to influence the global climate system (Oreskes, 2004; IPCC, 2007a; Anderegg et al., 2010). Climate models and observational data have shown that polar regions have warmed at substantially higher rates than the global mean (IPCC, 2007c).

  • The synthesis includes empirical data from on-going studies of the dehesa and grazing behavior and performance of Iberian pigs finished on acorns. The authors conclude that farmers conserve, prune and reforest oaks to maintain fruit production to feed and fatten Iberian pigs during the montanera or pannage, which result in conservation of biodiversity and associated ecosystem services.

  • This book consists of eight chapters, which are broadly divided into two themes. The first five chapters examine design features and management practices of selected agroforestry practices, and their effects on ecosystem functions and productivity. In the first Chapter, Rodríguez-Estéz et al. provide a synthesis of existing knowledge on the ecology of the dehesa, a Mediterranean agrosilvopastoral system, and how the Iberian pig production system enhances biodiversity and ecosystem services....
