A symposium on biophysical ecology was held at The University of Michigan Biological Station on Douglas Lake August 20-24, 1973. Biophysical ecology is an approach to ecology which uses fundamental principles of physics and chemistry along with mathematics as a tool to understand the interactions between organisms and their environment. It is fundamentally a mechanistic approach to ecology, and as such, it is amenable to theoretical modeling. A theoretical model applied to an organism and its interactions with its environ ment should include all the significant environmental factors, organism properties, and the mechanisms that connect these things together in an appropriate organism response. The purpose of a theoretical model is to use it to explain observed facts and to make predictions beyond the realm of observation which can be verified or denied by further observation. If the predictions are confirmed, the model must be reasonably complete except for second or third-order refinements. If the pre dictions are denied by further observation, one must go back to the basic ideas that entered the model and decide what has been overlooked or even what has been included that perhaps should not have been. Theoretical modeling must always have recourse to experiment in the laboratory and observation in the field. For plants, a theoretical model might be formulated to explain the manner and magnitude by which various environmental factors affect leaf temperature.

D.A. Cooke and R.K. Scott Sugar beet is one of just two crops (the other being sugar cane) which constitute the only important sources of sucrose - a product with sweeten ing and preserving properties that make it a major component of, or additive to, a vast range of foods, beverages and pharmaceuticals. Sugar, as sucrose is almost invariably called, has been a valued compo nent of the human diet for thousands of years. For the great majority of that time the only source of pure sucrose was the sugar-cane plant, varieties of which are all species or hybrids within the genus Saccharum. The sugar-cane crop was, and is, restricted to tropical and subtropical regions, and until the eighteenth century the sugar produced from it was available in Europe only to the privileged few. However, the expansion of cane production, particularly in the Caribbean area, in the late seventeenth and the eighteenth centuries, and the new sugar-beet crop in Europe in the nineteenth century, meant that sugar became available to an increasing proportion of the world's population.

It has been ten years since the publication of the third edition of this seminal text on plant virology, during which there has been an explosion of conceptual and factual advances. The fourth edition updates and revises many details of the previous editon, while retaining the important older results that constitute the field's conceptual foundation. Key features of the fourth edition include:* Thumbnail sketches of each genera and family groups* Genome maps of all genera for which they are known* Genetic engineered resistance strategies for virus disease control* Latest understanding of virus interactions with plants, including gene silencing* Interactions between viruses and insect, fungal, and nematode vectors* New plate section containing over 50 full-color illustrations

Plant Diseases An Advanced Treatise, Volume III: How Plants Suffer from Disease deals with the mechanism on how individual plants suffer from disease. Organized into 19 chapters, this volume discusses plant growth, the conceptual theory of disease development in plants, and the occurrence of different kinds of impairment in diseased plant system. The opening chapters outline the array of physiological functions that are essential in the growth and development of healthy plants. This text also describes the effect of disease on the capture, transfer, and utilization of energy by plants. The subsequent chapters discuss specific types of dysfunction in plant system, including food flow, water system, mineral nutrition, and growth alteration. Other chapters deal with other plant diseases, such as crown gall, teratoma, dysfunction and shortfalls of symbiont responses, disrupted reproduction, and tissue disintegration. This volume also examines various physical factors of the environment that impose mechanical or other physical stresses on plants. It also discusses the engineering mechanics of growing plants and the effect of various pathogens and microorganisms on plant strength and plant organ structural integrity. Other chapters deal with the effect of disease on cell membrane and permeability and on intermediary plant metabolism. The concluding chapters cover the genetic aspects of diseased plants and the diseases that induce senescence and diseases that senescence induced. This volume is an invaluable source for plant pathologists and researchers, mycologists, virologists, and graduate students.

In this major 1993 work, Lloyd Evans provides an integrated view of the domestication, adaptation and improvement of crop plants, bringing together genetic diversity, plant breeding, physiology and aspects of agronomy. Considerations of yield and maximum yield provide continuity throughout the book. Food, feed, fibre, fuel and pharmaceutical crops are all discussed. Cereals, grain legumes and root crops, both temperate and tropical, provide many of the examples, but pasture plants, oilseeds, leafy crops, fruit trees and others are also considered. After the introductory chapter, the increasing significance of crop yields to the world's food supply is highlighted. The next three chapters consider changes to crop plants over the last ten thousand years, including domestication, adaptation and improvement. Aimed at research workers and advanced students in crop physiology and ecology, agronomy and plant breeding, this book also reaches conclusions of relevance to those concerned with developmental policy, agricultural research and management, environmental quality, resource depletion and human history.
