This book describes the ecoregions of Saskatchewan, following a hierarchical framework for terrestrial ecosystems in Canada. The introduction reviews ecological land classification and the various interrelated factors that are involved in the development of ecosystems: geology, water, climate, vegetation, soils, wildlife, and human impacts. The main section describes the province within the context of the four ecozones and 11 ecoregions that were identified in the framework. For each ecoregion, the book provides a description of the physical setting, such as geology & climate, as well as the biological features that have developed in response to this physical environment. The impact of human activities on the ecology of the area concludes each of these descriptions. Appendices include lists of animal & plant species found in Saskatchewan and a glossary.

This book provides a comprehensive review of drilling technologies in the polar regions, from the portable drilling equipment for shallow sampling and coring, to heavy drilling equipment for deep onshore and offshore drilling. Particular attention is given to safe drilling methods in permafrost. In recent years, interest in drilling in the polar regions has increased under the pressure of the geopolitical “rush” and the undiscovered resource potential. In addition, borehole monitoring of permafrost thermal states is urgently needed to obtain evidence of climate change. The book focuses on the latest drilling technologies but also discusses the historical development of sampling, and drilling tools and devices, over the last 60–70 years providing valuable insights into a way forward and future possibilities.

Originally published in 1974, Arctic and Alpine Environments examines, the relatively simple ecosystems of arctic and alpine lands that still occupy extensive areas little disturbed by modern technology. The book argues that there is a necessity for carefully controlled development of the resources of these regions and suggests that there is a risk of irreversible disturbance without full understanding of these regions. This book provides a detailed documentation of cold-stressed arctic and alpine terrestrial environments and systematically deals with the present and past physical environment – climate, hydrology and glaciology; biota – treeline, vegetation, vertebrate zoology, and historical biogeography; abiotic processes – geomorphological and pedological and the role of man – bioclimatology, archaeology and technological impact, including radioecology. The book will appeal to academics and students of environmental and biological science, as well as providing a significant source for conservationists’, government agencies and industrial organizations.
