Book Description
The present work is intended as a guide or manual to the 340 species and major geographical races of flowering plants and ferns that comprise the vascular flora as it is known at present of the Canadian Arctic Archipelago. Besides conventional keys to families, genera, and species, it contains brief descriptions, line drawings, and maps showing the North American ranges of all species. For each species brief notes are given on local occurrence, soil preferences, economic uses, if any, and on their total or world distribution. A glossary explains the meaning of all special botanical terms used throughout the text ; at the end an index is provided to species, illustrations, and maps.

Book Description
This 2001 book provides a selective annotated bibliography of the principal floras and related works of inventory for vascular plants. The second edition was completely updated and expanded to take into account the substantial literature of the late twentieth century, and features a more fully developed review of the history of floristic documentation. The works covered are principally specialist publications such as floras, checklists, distribution atlases, systematic iconographies and enumerations or catalogues, although a relatively few more popularly oriented books are also included. The Guide is organised in ten geographical divisions, with these successively divided into regions and units, each of which is prefaced with a historical review of floristic studies. In addition to the bibliography, the book includes general chapters on botanical bibliography, the history of floras, and general principles and current trends, plus an appendix on bibliographic searching, a lexicon of serial abbreviations, and author and geographical indexes.

Book Description
The Boreal Ecosystem presents an overview of the state of knowledge on the boreal forest region of North America, with extensive reference to the boreal regions of Europe and Asia. Initial sections of this book deal with aspects of the floristic composition and evolutionary history of the boreal vegetation. These introduce subsequent discussions on the processes at work in vegetation, soils, and the atmosphere—in short, with the boreal forest as an ecosystem, the sum total of the influences of many closely interlaced biotic and physical factors. These include not only plant species that make up the visible vegetation but also nutrients, soil, temperature, rainfall, progression of the seasons, soil microflora, arthropods, insects, and larger animals such as marten, otter, beaver, moose, caribou, bear, and wolf, and man. All are closely linked strands in the web of life, a web apart from, yet dependent on and influencing, the raw physical environment. This book should serve as an introduction and reference source to its audience: undergraduate and graduate students in the biological and ecological disciplines, research workers in these fields as well as in related areas such as soil science, agronomy, genetics, and climatology; in short, everyone with an interest in boreal ecology.

Book Description
This book is a practical, portable guide to all of the Arctic's natural history—sky, atmosphere, terrain, ice, the sea, plants, birds, mammals, fish, and insects—for those who will experience the Arctic firsthand and for armchair travelers who would just as soon read about its splendors and surprises. It is packed with answers to naturalists' questions and with questions—some of them answered—that naturalists may not even have thought of.

Book Description
The Periglacial Environment, Fourth Edition, is an authoritative overview of the world’s cold, non-glacial environments. First published in 1976 and subsequently revised in 1996 and 2007, the text has been the international standard for nearly 40 years. The Fourth Edition continues to be a personal interpretation of the frost-induced conditions, geomorphic processes and landforms that characterize periglacial environments. Part One discusses the periglacial concept and describes the typical climates and ecosystems that are involved. Part Two describes the geocryology (permafrost science) associated with frozen ground. Part Three outlines the weathering and geomorphic processes associated with cold-climate conditions. Part Four provides insight into the periglacial environments of the Quaternary, especially the Late Pleistocene. Part Five describes some of the problems associated with human occupancy in regions that experience frozen ground and cold-climate conditions. Extensively revised and updated Written by an expert with over 50 years of field research Draws upon the author’s personal experience from Northern Canada, Alaska, Siberia, Tibet, Antarctica, Svalbard, Scandinavia, southern South America, Western Europe and eastern North America This book is an invaluable reference for advanced undergraduates in geography, geology, earth sciences and environmental sciences programs, and to resource managers and geotechnical engineers interested in cold regions.

Book Description
This authoritative impartial scientific account by a recognised expert, will be of interest to planning officers, ski companies, skiers, hill-walkers and mountaineers as well as the many in the public who appreciate wildlife and the Scottish countryside. The first part of this book presents the evidence of the author as the main scientific witness at the 1981 Lurcher's Gully Public Inquiry into proposals for ski developments on Cairn Gorm. The Inquiry examined human impacts for a week and remains the most thorough Inquiry on this topic so far in Scotland. Following the decision of the Reporter in charge of the Inquiry, the Secretary of State for Scotland rejected the proposals. In the second part of the book the author presents his unpublished research on certain aspects of the Inquiry that he continued to study afterwards, in more detail.
