Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Answers to practical questions about plant growth are sought with increasing urgency. Climate change is affecting the stability of vegetation, the yield of many important crops, and there is a continual need for ever more productive varieties to feed a growing global population. Answering questions posed by these problems requires a more integrated understanding of how plants function in producing growth. This book shows how this understanding can be achieved. First and foremost, plant growth must be defined as a dynamic system with developmental, morphological, and physiological processes responding to fluctuations in the environment due to weather, changes in the architecture of the plant as it grows, and the effects of plants on their environment: connecting these processes in a complete system is the essential integration. Part I shows, for contrasting plant types, that developmental, morphological, and physiological processes must all be considered to explain differences in growth and survival; Part II defines the types of control processes occurring in plants and their different functions; Part III illustrates the importance of plant morphology in controlling growth; Part IV how, and to what extent, the effects of environmental factors are controlled by plant processes particularly as plants grow in size. A final chapter defines how a theory for growth of a particular plant must be based on its characteristics as a dynamic system.

Scientists tend to take the thought processes that drive their research for granted, often learning them indirectly by observing their supervisors and colleagues. This book emphasizes the advantages of being explicit about these thought processes and aims to help those undertaking ecological research to develop a critical attitude to approaching a scientific problem and constructing a procedure for assessment. The outcome is a text that provides a framework for understanding methodological issues and which assists with the effective definition and planning of ecological research. As such, it represents a unique resource for anyone embarking on their research career. It also provides a valuable source of information for those more experienced researchers who are seeking to strengthen the methodology underlying their studies or who have an interest in the analysis of research methods in ecology.

This Very Short Introduction provides both the believer and non-believer with a balanced survey of the central questions of theology. David Ford's approach draws us in to considering the principles underlying religious belief, including the centrality of salvation to most major religions, the concept of God in ancient, modern, and postmodern contexts, the challenge posed to theology by prayer and worship, and the issue of sin and evil. He also probes the nature of experience, knowledge, and wisdom in theology, and discusses what is involved in interpreting theological texts. In this new edition, Ford considers the contemporary relevance of theology, including the effect of globalization and digitized communication, examines the theological responses to change and development in science, considers the impact of increased engagement between Islam and the West, and looks at the development and importance of theology between the different faiths.
