Book Description
Leaves are among the most abundant organs on earth and are a defining feature of most terrestrial ecosystems. However, a leaf is also a potential meal for a hungry animal and the question therefore arises, why does so much foliage survive in nature? What mechanisms protect leaves so that, on a global scale, only a relatively small proportion of living leaf material is consumed? Leaf survival is in large part due to two processes: firstly, leaf-eating organisms fall prey to predators (top-down pressure on the herbivore); secondly, leaves defend themselves (bottom-up pressure on the herbivore). Remarkably, these two types of event are often linked; they are controlled and coordinated by plants and the molecular mechanisms that underlie this are now beginning to emerge. This novel text focuses exclusively on the leaf, on the herbivorous organisms that attack leaves, and the mechanisms that plants use to defend these vital organs. It begins with an assessment of the scale of herbivory, before examining direct physical and chemical defences on leaf surfaces and within the leaf itself. Although some leaf defences are easily seen, most operate at the molecular level and are therefore invisible to the naked eye. Many of these recently elucidated mechanisms are described. Throughout the book, perspectives from both the laboratory and the field are combined. A central feature of the work is its emphasis on the coevolution of leaf defences and the digestive tracts of animals including humans, making the book of relevance in understanding the role of leaf defences in agriculture. Leaf Defence is suitable for senior undergraduate and graduate students taking courses in plant science, as well as a broader audience of biologists and biochemists seeking a comprehensive and authoritative overview of this exciting and emerging topic.

Book Description
The study of phytoliths—inorganic silica remnants plants leave behind when they die and decay—has developed dramatically over the last twenty years. New publications have documented a diverse array of phytoliths from many regions around the globe, while new understandings have emerged as to how and why plants produce phytoliths. Together, these developments make phytoliths a powerful tool in reconstructing past environments and human uses of plants. In Phytoliths, Dolores Piperno makes sense of the discipline for both those working directly with phytoliths in the field or the lab as well as for those who rely on the results of phytolith studies for their own research. Including over a hundred images, Piperno's book will be of great benefit to archaeologists and paleobotanists in the classroom or the lab.

Book Description
All animals feed selectively. This book examines the selectivity of feeding from a variety of viewpoints. It examines the viewpoint of the behavioural ecologist that considers decision rules, the dietitian that looks at nutritional problems, and the community ecologist that sees feeding as a factor influencing species diversity. The text brings these diverse disciplines together to produce a coherent view of the way in which organisms 'choose' their diet. Optimal foraging theory has brought the study of foraging behaviour, particularly diet selection to a point where physiological, nutritional, psychological, morphological and ecological factors can begin to be addressed in a coherent fashion. This book is not another exposition of optimal foraging theory, but it does draw on the applications and limitations of the theory to demonstrate the great potential for the development of diet selection as an interdisciplinary subject. Authoritative synthesis of the latest thinking in optimal foraging and feeding theory. Adopts, for the first time, a truly interdisciplinary approach to diet selection. Authored by experts from each of the contributing fields.

Book Description
Recent research indicates that plants may be defended by mechanisms activated only after a plant has been challenged by a herbivore. Examines these inducible defenses and provides a framework for future advances in the field. Also serves as a summary and compilation of major studies to date on important areas of plant and insect ecology. While treating both vertebrates and invertebrates it covers mechanisms and models of long- and short-term induction. The impact of inducible phytochemicals on herbivores is extensively discussed as are pesticidal activity of inducible phytochemicals. Covers agricultural implications of inducible phytochemicals.
