This is a biography of Wilson Alwyn Bentley, the farmer from Jericho, Vermont, who took over five thousand photomicrographs of ice, dew, frost, and -- especially -- snow crystals. Although his photographs were taken between 1885 and 1931, they have never been equalled and are in great demand today. Bentley's story is one of courage and persistence against tremendous odds. He taught himself how to photograph snow crystals through a microscope while still in his teens and then pursued his obsession for years before having the beauty and scientific value of his work recognised by others. 'The Snowflake Man' lays open the life of a simple, self-educated, sensitive man who pursued natural beauty with microscope and camera for nearly fifty years. The book contains 30 black and white photographs.

Mammals in the genus Martes are mid-sized carnivores of great importance to forest ecosystems. This book, the successor to Martens, Sables, and Fishers: Biology and Conservation, provides a scientific basis for management and conservation efforts designed to maintain or enhance the populations and habitats of Martes species throughout the world. The twenty synthesis chapters contained in this book bring together the perspectives and expertise of sixty-three scientists from twelve countries, and are organized by the five key themes of evolution and biogeography, population biology and management, habitat ecology and management, research techniques, and conservation. Recent developments in research technologies such as modeling and genetics, biological knowledge about pathogens and parasites, and concerns about the potential effects of global warming on the distribution and status of Martes populations make new syntheses of these areas especially timely. The volume provides an overview of what is known while clarifying initiatives for future research and conservation priorities, and will be of interest to mammalogists, resource managers, applied ecologists, and conservation biologists.

Particularly valuable for Ronda's inclusion of pertinent background information about the various tribes and for his ethnological analysis. An appendix also places the Sacagawea myth in its proper perspective. Gracefully written, the book bridges the gap between academic and general audiences.OCo"Choice""
