Book Description
This book challenges the precedent that a mountain's worth scales with height. It is a rational synthesis of new concepts that compel one to reassess the popular "heightist mindset". The concept of prominence, loosely defined as a mountain's vertical relief, is a stiff competitor to summit height for assessing a mountain's stature and relative worth for innumerable purposes. The community of prominence theoreticians, list builders, and climbers has reached critical mass - suggesting publication of a book dedicated exclusively to prominence. Revolutions are not overnight. The heightist mindset has minimally a 100 year head start. Eventually the climbing community will embrace prominence. For the mountaineer a prominence-based peak list provides fresh goals guaranteed to satisfy. A prominence-based peak list, regardless of geographic region, incorporates the most awe inspiring and diverse mountains. Chapter I introduces prominence, being defined and contrasted with altitude as peak list generator. Chapters II and III concern peak list production. Chapter IV reviews the history of prominence, including a compendium of prominence list builders and their lists. Chapter V is about prominence oriented peakbaggers and their accomplishments. Chapter VI entails prominence-derived mountain measures - submarine prominence, inverse prominence, proportional prominence, and dominance. Chapter VII concerns the advanced, prominence-derived concepts of parentage, divide trees, lineage cells, and more. Chapter VIII concerns alternative, objective mountain measures: isolation measure; peakedness and prominence density; and height / steepness combination measures - drop measure, cliff measure, spire measure, and ruggedness measure. Spire measure quantifies a mountain's subjective impressiveness due to great angularity. Chapter IX is a search for the largest prominence unclimbed mountain - grand goal of a future, summit-discovering expedition. Appendices A to G cover various subtopics, the glossary defines over 300 terms. 48 pages of illustrations are included, with full-color versions on-line at http://www.cohp.org/prominence/publication_2005_illustrations/main.html A beautiful, hardcover edition with color illustrations is available, and is highly recommended by book reviewers. ?

Book Description
The Yukon is a land of remarkable wilderness, diverse ecosystems, and profound beauty. It is also home to a unique assemblage of birds. As of 2002, 288 bird species have been documented in the Yukon, with 223 occurring regularly. They occupy an amazing range of habitats, from the most barren mountain peaks to lush valley bottom forests, and are an integral part of the cultural heritage of Yukon First Nations people. The vast areas of natural habitat with limited road access can make the study of birds challenging, but are key in defining the nature of birding in the Yukon. Birds of the Yukon Territory is the result of a decade-long project initiated to gather and share what is known about the Yukon's birdlife. Lavishly illustrated with 600 colour photographs and 223 hand-drawn bird illustrations, the book presents a wealth of information on bird distribution, migration and breeding chronology, nesting behaviour, and habitat use, and on conservation concerns. Two hundred and eighty-eight species of birds are documented, including 223 regular species, and 65 casual and accidental species. In compiling this meticulously researched volume, the authors consulted over 166,000 records in a database created by the Canadian Wildlife Service, with information dating back to 1861. S ections on birds in Aboriginal culture and history, and bird names in the Yukon First Nations and Inuvialuit languages, enhance the book, as do the numerous easily interpreted charts and graphs. Destined to become a basic reference work on the avifauna of the North, Birds of the Yukon Territory is a must-have for bird enthusiasts and anyone interested in the natural history of the Yukon and the North.

Book Description
This panoramic chronicle of Alaska captures the grandeur of its geography, history, and many larger-than-life personalities: “Just plain terrific” (Bradford Washburn). The history of Alaska is filled with stories of new land and new riches—and ever present are new people with competing views on how these valuable resources should be used. Here are the stories of Russians exploiting a fur empire; explorers checking rival advances; prospectors stampeding to the clarion call of “Gold!”; soldiers battling out a decisive chapter in WWII; oil wildcatters looking for a different kind of mineral wealth; and always at the core of these disputes is the question of how the land itself is to be used—and by whom. While some want Alaska to remain static, others are in the vanguard of change. Alaska: Saga of a Bold Land shows that there are no easy answers on either side of this perennial debate, and that Alaska will always be crossing the next frontier.

Book Description
In this book entitled "The Biosphere", researchers from all regions of the world report on their findings to explore the origins, evolution, ecosystems and resource utilization patterns of the biosphere. Some describe the complexities and challenges that humanity faces in its efforts to experiment and establish a new partnership with nature in places designated as biosphere reserves by UNESCO under its Man and the Biosphere (MAB) Programme. At the dawn of the 21st century humanity is ever more aware and conscious of the adverse consequences that it has brought upon global climate change and biodiversity loss. We are at a critical moment of reflection and action to work out a new compact with the biosphere that sustains our own wellbeing and that of our planetary companions. This book is a modest attempt to enrich and enable that special moment and its march ahead in human history.

Book Description
This book is the definitive guide to the largest and most charismatic species of falcon in the world, the Gyrfalcon. With detailed information on life history characteristics, ecology, conservation issues, and much more, the book presents the most accurate, up-to-date, and complete view of this spectacular bird ever published. Drawing on extensive research and travel to every country within the range of the Gyrfalcon, Eugene Potapov and Richard Sale delineate a new map of the bird’s range, conclude that the Gyrfalcon is more adaptable than previously thought, and restore the traditional Linnean scientific name of the species, Falco gyrfalco. The authors also reveal that Gyrfalcons, for much of their lives, are true stenophagous raptors, a rarity not only among raptors but among all birds. Elegantly illustrated with many photographs and line drawings, this is an essential volume for ornithologists, ecologists, wildlife rehabilitators, falconers, and all others fascinated by birds of prey.
