This report addresses and synthesizes the current state of scientific understanding regarding potential abrupt state changes or regime shifts in ecosystems in response to climate change. It provides an overview of what is known about ecological thresholds and where they are likely to occur. The report also identifies those areas where research is most needed to improve knowledge and understand the uncertainties regarding them. It suggests a suite of potential actions that land and resource managers could use to improve the likelihood of success for the resources they manage, even under conditions of incomplete understanding of what drives thresholds of change and when changes will occur.

The 11 papers in this document address issues and needs in the development and stewardship of Central Asia rangelands, and identify directions for future work. With its vast rangelands and numerous pastoral populations, Central Asia is a region of increasing importance to rangeland scientists, managers, and pastoral development specialists. Five of the papers address rangeland issues in Mongolia, three papers specifically address studies in China, two papers address Kazakhstan, and one paper addresses the use of satellite images for natural resource planning across Central Asia. These papers comprise the proceedings from a general technical conference at the 2004 Annual Meeting of the Societ...
Canadian Geography: A Scholarly Bibliography is a compendium of published works on geographical studies of Canada and its various provinces. It includes works on geographical studies of Canada as a whole, on multiple provinces, and on individual provinces. Works covered include books, monographs, atlases, book chapters, scholarly articles, dissertations, and theses. The contents are organized first by region into main chapters, and then each chapter is divided into sections: General Studies, Cultural and Social Geography, Economic Geography, Historical Geography, Physical Geography, Political Geography, and Urban Geography. Each section is further sub-divided into specific topics within each main subject. All known publications on the geographical studies of Canada—in English, French, and other languages—covering all types of geography are included in this bibliography. It is an essential resource for all researchers, students, teachers, and government officials needing information and references on the varied aspects of the environments and human geographies of Canada.
