This book has a very strong practical orientation, telling readers what methodologies are available using stable isotopes, how studies should be designed and executed to maximise effectiveness and incisiveness in terms of data obtained and outcomes in terms of understanding events and processes in plant and ecosystem functioning. The readership is very much aimed toward postgraduates with good knowledge of general biological principles and underlying chemical and physical processes. Pre-existing knowledge of or experience in application and assay of stable isotopes is not required. The stable isotope research field is one of the most rapidly growing areas of ecophysiology and techniques using stable isotopes comprise an ever increasing component of research programs of university postgraduates and a wide range of agencies conducting environmental monitoring and rehabilitation programs. The book is tailor-made for such an audience.

“To follow the journeys made by Mackay and Evans up the Missouri and across the plains in 1795–97 is to begin to appreciate the kind of world Lewis and Clark found when they voyaged up the river in 1804. . . . Of all those waterways, none has captured the American imagination more than the Missouri. . . . It is a river of promise, of dreams, and of dreams denied.” –James P. Ronda, from the Foreword When Mackay and Evans returned to Spanish St. Louis in 1797, they were hailed as “the two most illustrious travelers in the northern parts of this continent.” Ironically, though the findings of Mackay and Evans were responsible for much of the early success of Lewis and Clark in their expedition, the adulation that followed Lewis and Clark’s successful return completely eclipsed Mackay and Evans’s reputations. In Prologue to Lewis and Clark, W. Raymond Wood narrates the history of this long-forgotten but important expedition up the Missouri River. The Mackay and Evans expedition was more than an exploratory mission. It was the last effort by Spain to gain control over the Missouri River basin in the decade before the United States purchased the Louisiana territory. In that respect, it failed. But the expedition was successful as a journey of exploration. The maps and documents they created later provided the Lewis and Clark expedition with invaluable information for its first full year. Consolidating a collection of eighteen contemporary documents relating to the Mackay and Evans expedition as well as his own research and analysis, Wood provides an in-depth examination of the expedition’s background, execution, and final results.

Maps and atlases are created as soon as information on our geography has been clarified. They are used to find directions or to get insight into spatial relations. They are produced and used both on paper as well as on-screen. The Web is the new medium for spreading and using maps. This book explains the benefits of this medium from the perspective of the user, and the map provider. Opportunities and pitfalls are illustrated by a set of case-studies. A website accompanies the book and provides a dynamic environment for demonstrating many of the principles set out in the text, including access to a basic course in Internet cartography as well as links to other interesting places on the Web. Professor Kraak looks at basic questions such as "I have this data what can I do with it?" and discusses the various functions of maps on the web. Web Cartography also looks at the particularities of multidimensional web maps and addresses topics such as map contents (colour, text and symbols), map physics (size and resolution), and the map environment (interface design/site contents).
