    Abstract: The islands of the Pacific and East Indies made an enormous and fateful impact on the minds of Charles Darwin and Alfred Wallace, the fathers of modem evolutionary theory. Since then island floras and faunas have continued to playa central role in the development of evolutionary, and more recently ecological thought. For much ofthis century island ecology was a descriptive science and a wealth of information has been amassed on patterns of species distributions, on the composition of island floras and faunas, on the classification of islands into types such as oceanic and continental, on the taxonomic description of insular species and sub-species and on the adaptations, often bizarre, of island creatures. However, biologists are not satisfied for long with the mere collection of data and the description of patterns, but seek unifying theories. Island ecology was transformed into a predictive science by the publication, in 1967, of MacArthur and Wilson's Theory of Island Biogeography. This, perhaps the most influential book written on island ecology, has been the stimulus for a generation of theoretical ecologists and gifted field workers. The books listed below in the bibliography will indicate to the reader the vast scope of island ecology and the changes in approach that have taken place over the years.

    Abstract: There are good reasons why the subject of electric power engineering, after many years of neglect, is making a comeback in the undergraduate curriculum of many electrical engineering departments. The most obvious is the current public awareness of the "energy crisis. " More fundamental is the concern with social responsibility among college students in general and engineering students in particular. After all, electric power remains one of the cornerstones of our civilization, and the well-publicized problems of ecology, economy, safety, dependability and natural resources management pose ever-growing challenges to the best minds in the engineering community. Before an engineer can successfully involve himself in such problems, he must first be familiar with the main components of electric power systems. This text­ book will assist him in acquiring the necessary familiarity. The course for which this book is mainly intended can be taken by any student who has had some cir­ cuit analysis (using discrete elements, and including sinusoidal steady state) and elementary electromagnetic field theory. Most students taking the course will be in their junior or senior years. Once the course is completed, students may decide to go more deeply into the design and operation of these components and study them on a more advanced level, or they may direct their attention to the problems of the system itself, problems which are only hinted at briefly at various points herein.

    Abstract: This book is about scientific theories of a particular kind - theories of mathematical physics. Examples of such theories are classical and relativis­ tic particle mechanics, classical electrodynamics, classical thermodynamics, statistical mechanics, hydrodynamics, and quantum mechanics. Roughly, these are theories in which a certain mathematical structure is employed to make statements about some fragment of the world. Most of the book is simply an elaboration of this rough characterization of theories of mathematical physics. It is argued that each theory of mathematical physics has associated with it a certain characteristic mathematical struc­ ture. This structure may be used in a variety of ways to make empirical claims about putative applications of the theory. Typically - though not necessarily - the way this structure is used in making such claims requires that certain elements in the structure play essentially different roles. Some playa "theoretical" role; others playa "non-theoretical" role. For example, in classical particle mechanics, mass and force playa theoretical role while position plays a non-theoretical role. Some attention is given to showing how this distinction can be drawn and describing precisely the way in which the theoretical and non-theoretical elements function in the claims of the theory. An attempt is made to say, rather precisely, what a theory of mathematical physics is and how you tell one such theory from anothe- what the identity conditions for these theories are.

    Abstract: Vegetation dynamics is an important subject. A knowledge and under­ standing of it is central to the science of vegetation management-in grassland, range and nature reserve management, and in aspects of wildlife management, forestry and agricultural crop production. It is also a large and diffuse subject. In a small book such as this I had to be highly selective, and could not do equal justice to all aspects. I have had therefore to condense many examples, and more regrettably, many arguments. While I have tried to present a broad selection of topics and examples, the content inevitably reflects my own special interests and experience. The study of vegetation and its dynamics does not lend itselfto neat and tidy divisions, and the way of allotting material into different chapters here is arbitrary. I have used Chapter I to introduce a number of ideas, beginning with the nature of vegetation in space, then passing to an introduction to the nature of changes in vegetation with time, in particular those generally known as successions. The book also contains a number of asides to the text's central arguments; I hope the reader finds these interesting rather than disconcerting.

    Abstract: Plants, in addition to their role as primary synthesizers of organic com­ pounds, have evolved as selective accumulators of inorganic nutrients from the earth's crust. This ability to mine the physical environment is restricted to green plants and some microorganisms, other life forms being direct1y or indirect1y dependent on this process for their supply of mineral nutrients. The initial accumulation of ions by plants is of ten spatially separated from the photosynthetic parts, necessitating the transport to these parts of the inorganic solutes thus acquired. The requirement for energy-rich materials by the accumulation process is provided by a transport in the opposite direction of organic solutes from the photosynthetic areas. These transport phenomena in plants have been studied at the cellular level, the tissue level, and the whole plant level. The basic problems of analysing the driving forces and the supply of energy for solute transport remain the same for alI systems, but the method of approach and the type of results obtained vary widely with the experimental material employed, reflecting the variation of the solute transporting properties which have se1ectively evolved in response to both internal and external environmental pressures.

    Abstract: between the organ systems of cephalopods and those of less ambitious molluscs. Octopus does, as we would predict, live close to the limits set by its own physiology. The circulation, to take one example, is barely adequate for such an active animal, mainly because of the absence of any system for pack­ aging the blood pigment; haemocyanin in solution is a poor oxygen carrier. Cephalopod blood can transport less than 5 millilitres of oxygen per 100 ml of blood (compared with about 15 vol% in fish) and the whole supercharged system of triple hearts, high blood pressure and pulsating blood vessels succeeds only in returning blood that retains less than 30% of its dissolved oxygen by the time it reaches the gills. This at rest; the effect of exercise is immediate and surprisingly long­ lasting even in octopuses as small as 300 g, which must very swiftly run into oxygen debt when they flee from predators or pursue their prey (Sections 3.2.2, 3.2.4). Digestion, too would seem to be limiting. As with other molluscs, digestion in Octopus is based on secretion­ absorption cycles by a massive diverticulum of the gut, an adequate system in a less hectic past, but scarcely appropriate in a predator that must be an opportunist in the matter of feeding. Octopus feeds mainly at night, and spends a great deal of every day sitting at home.

    Abstract: In a mathematical programming problem, an optimum (maxi­ mum or minimum) of a function is sought, subject to con­ straints on the values of the variables. In the quarter century since G. B. Dantzig introduced the simplex method for linear programming, many real-world problems have been modelled in mathematical programming terms. Such problems often arise in economic planning - such as scheduling industrial production or transportation - but various other problems, such as the optimal control of an interplanetary rocket, are of similar kind. Often the problems involve nonlinear func­ tions, and so need methods more general than linear pro­ gramming. This book presents a unified theory of nonlinear mathe­ matical programming. The same methods and concepts apply equally to 'nonlinear programming' problems with a finite number of variables, and to 'optimal control' problems with e. g. a continuous curve (i. e. infinitely many variables). The underlying ideas of vector space, convex cone, and separating hyperplane are the same, whether the dimension is finite or infinite; and infinite dimension makes very little difference to the proofs. Duality theory - the various nonlinear generaliz­ ations of the well-known duality theorem of linear program­ ming - is found relevant also to optimal control, and the , PREFACE Pontryagin theory for optimal control also illuminates finite dimensional problems. The theory is simplified, and its applicability extended, by using the geometric concept of convex cones, in place of coordinate inequalities.

    Abstract: viii homology groups. A weaker result, sufficient nevertheless for our purposes, is proved in Chapter 5, where the reader will also find some discussion of the need for a more powerful in­ variance theorem and a summary of the proof of such a theorem. Secondly the emphasis in this book is on low-dimensional examples the graphs and surfaces of the title since it is there that geometrical intuition has its roots. The goal of the book is the investigation in Chapter 9 of the properties of graphs in surfaces; some of the problems studied there are mentioned briefly in the Introduction, which contains an in­ formal survey of the material of the book. Many of the results of Chapter 9 do indeed generalize to higher dimensions (and the general machinery of simplicial homology theory is avai1able from earlier chapters) but I have confined myself to one example, namely the theorem that non-orientable closed surfaces do not embed in three-dimensional space. One of the principal results of Chapter 9, a version of Lefschetz duality, certainly generalizes, but for an effective presentation such a gener- ization needs cohomology theory. Apart from a brief mention in connexion with Kirchhoff's laws for an electrical network I do not use any cohomology here. Thirdly there are a number of digressions, whose purpose is rather to illuminate the central argument from a slight dis­ tance, than to contribute materially to its exposition.

    Abstract: The present scientific and technical revolution has brought science into the range of the most effective forces of production. The formula "science= production force" applies also to the social sciences whose explorations of human relationships and drives have reached previously unsuspected depths. Objectives, such as higher living standards and full employment, economic growth and stability, social equity and security, have both called for and provided a basis for the exploitation of possibilities offered by the natural and technical sciences. In today's agriculture, age-old traditions are in the process of disintegra­ tion, but the heredity of a century (or that of even a millennium as in Hungary) does not get dissolved without defending itself. Technical progress and social restratification, the emergence of new scales of values and preferences, the adjustment of the rural communities to their new tasks and conditions - all these have transformed farm operations and farming techniques. But agriculture, even under its revolutionized surface, still hides deep, almost untouched layers. If economists and agriculturalists are perplexed by the multitude and variety of the visible farm problems, there exist many others about which they can only guess, which they must follow up. In formulating and solving these problems, agricultural economists have professional tasks: (1) facilitating the most efficient use of agricultural resources from the standpoint of the national economy, and (2) helping farmers and farm people to attain their stated, socially feasible objectives.

    Abstract: Materials Science has now become established as a discipline in its own right as well as being of increasing importance in the fields of Physics, Chemistry and Engineering. To the student meeting this subject for the first time the combination of disciplines which it embraces represents a formidable challenge. He will require to understand the lan­ guage of the physicist and chemist as well as appreciate the practical uses and limita­ tions of solid materials. This book has been written as an introduction to the Physical Properties of Materials with these thoughts in mind. The mathematical content has been limited deliberately and emphasis is placed on providing a sound basis using simplified models. Once these are understood we feel that a mathematical approach is more readily assimilated and for this purpose supplementary reading is suggested. While the authors are deeply aware of the pitfalls in attempting such a treatment this is meant to be an essentially simple book to point the many avenues to be explored. We anticipate that the book will appeal to first and second year degree students in a variety of disciplines and may not prove too difficult for those studying appropriate Higher National Certificate and Diploma courses. Electrical engineers working in the field of materials applications may well find it useful as a guide to modern thinking about materials and their properties. The book begins with an introduction to some basic ideas of modern physics.

    Abstract: Since the first statement of the aims and methods of the Cambridge Growth Project, which appeared in 1962 as the first number of our former series A Programme for Growth, we have produced a volume on the state ofthe model and on projections derived from it at roughly five year intervals: Exploring 1970 (1965), Exploring 1972 (1970) and now the present book. A comparison of these publications shows the directions in which we have developed our model. First, we have been able to model more parts of the economy and to model them better; and, second, by adopting a targets-and-instruments approach, we have been able to tackle questions of policy. As a consequence of the first of these improvements, the model has become more closely knit and variables which were previously exogenous have become endogenous; and, as a consequence of the second, the model has become less rigid and can be used to suggest policies for correcting some ofthe undesir­ able features that emerge from the projections.
