In recent years there has been increased interest in growing willow and poplar trees, as fast-growing species that have several purposes, including use as biofuels for energy production. However, silviculture of these trees has been constrained by diseases such as Melampsora rusts. This book provides a comprehensive review of over two decades of extensive study of the rust diseases affecting willow and poplar. It provides insights into the population biology of Melampsora rusts in Europe, China, India and Chile, the genetics of their resistance, and their interaction with their hosts. The book offers information essential to the development of effective and sustainable disease control measures including the use of willow genotype mixtures and biological control agents.

This volume brings together the papers presented at a conference entitled 'Experiencing the Garden in the Eighteenth Century', held at the Institute of Romance Studies, Senate House, University of London on 13 March 2004. Speakers came from Europe, the United States and New Zealand, and each gave a very different perspective on the eighteenth-century landscape garden in England, France and elsewhere in Europe. The papers focused on the theme of experience, an especially important aspect of eighteenth-century garden design. Landscape gardens were created for visitors to move through on a journey from one place to the next: the garden would not be seen all at once, but would be experienced as a story unfolding. The visitor would follow a circuit around the garden, moving from light to shade, being given suggestive prompts with statues, temples and viewpoints, as if on a sensory, emotional and intellectual journey.
The Singularity School and Conference took place in Luminy, Marseille, from January 24th to February 25th 2005. More than 180 mathematicians from over 30 countries converged to discuss recent developments in singularity theory. The volume contains the elementary and advanced courses conducted by singularities specialists during the conference, general lectures on singularity theory, and lectures on applications of the theory to various domains. The subjects range from geometry and topology of singularities, through real and complex singularities, to applications of singularities.

Jean-Jacques Rousseau (1712-1778) is generally seen as one of the most important figures whose ideas had a great influence on the French Revolution (1789). Many immediately associate him with the concept of "the noble savage." However, just as with his political and philosophical writings, his love for botany and scenery would change the landscape of continental Europe, if not the world. This book presents a unique view of the young Rousseau's awakening love for plants, and his sometimes euphoric appreciation of the scenery during his endless walks. The author unfolds the development of Rousseau's concept of nature, which makes it possible to pinpoint the exact and pivotal moment of change i...
