The Cactus Primer presents the amateur cactophile with an excellent introduction to cactus biology and provides the informed reader with an invaluable summary of the last forty years' research. This book goes far beyond books that instruct readers in the propagation, growth, and care of these plants; addressing matters of more scientific interest, it takes an integrated approach to the presentation of the form, physiology, evolution, and ecology of cacti. The book is unique in that it combines the descriptive morphology and physiology documented in the scientific literature with more general observations found in popular publications on cacti. It provides a new generic classification of the cacti and contains much new information, including data on photosynthesis, heat and cold tolerance, computer modeling of ribs, and the effects of spines. Enhanced by over 400 illustrations and supplemented with an extensive glossary, this book will appeal to cactus enthusiasts interested in the classification and growth of cacti, as well as to plant biologists who use cacti to illustrate desert adaptation and convergent evolution. Written in accessible style, The Cactus Primer is bound to serve a dual function as both an instructive tool and a reference work in cactus biology for years to come.
Research polls, media interviews, and everyday conversations reveal an unsettling truth: citizens, while well-meaning and even passionate about current affairs, appear to know very little about politics. Hundreds of surveys document vast numbers of citizens answering even basic questions about government incorrectly. Given this unfortunate state of affairs, it is not surprising that more knowledgeable people often deride the public for its ignorance. Some experts even think that less informed citizens should stay out of politics altogether. As Arthur Lupia shows in Uninformed, this is not constructive. At root, critics of public ignorance fundamentally misunderstand the problem. Many experts believe that simply providing people with more facts will make them more competent voters. However, these experts fail to understand how most people learn, and hence don't really know what types of information are even relevant to voters. Feeding them information they don't find relevant does not address the problem. In other words, before educating the public, we need to educate the educators. Lupia offers not just a critique, though; he also has solutions. Drawing from a variety of areas of research on topics like attention span and political psychology, he shows how we can actually increase issue competence among voters in areas ranging from gun regulation to climate change. To attack the problem, he develops an arsenal of techniques to effectively convey to people information they actually care about. Citizens sometimes lack the knowledge that they need to make competent political choices, and it is undeniable that greater knowledge can improve decision making. But we need to understand that voters either don't care about or pay attention to much of the information that experts think is important. Uninformed provides the keys to improving political knowledge and civic competence: understanding what information is important to and knowing how to best convey it to them.

New information has been added and valuations updated, making it possible to establish the value of any note. Paper Money of the United States has been an invaluable asset to currency collectors and numismatists.

Winner of the Pacific Northwest Booksellers Award Bounded on the east by the crest of the Cascade Range and on the west by the lofty east flank of the Olympic Mountains, Puget Sound terrain includes every imaginable topograhic variety. This thoughtful and eloquent natural history of the Puget Sound region begins with a discussion of how the ice ages and vulcanism shaped the land and then examines the natural attributes of the region--flora and fauna, climate, special habitats, life histories of key organisms--as they pertain to the functioning ecosystem. Mankind's effects upon the natural environment are a pervasive theme of the book. Kruckeberg looks at both positive and negative aspects of human interaction with nature in the Puget basin. By probing the interconnectedness of all natural aspects of one region, Kruckeberg illustrates ecological principles at work and gives us a basis for wise decision-making. The Natural History of Puget Sound Country is a comprehensive reference, invaluable for all citizens of the Northwest, as well as for conservationists, biologists, foresters, fisheries and wildlife personnel, urban planners, and environmental consultants everywhere. Lavishly illustrated with over three hundred photographs and drawings, it is much more than a beautiful book. It is a guide to our future.
