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.

Ecology and Evolution of Cancer is a timely work outlining ideas that not only represent a substantial and original contribution to the fields of evolution, ecology, and cancer, but also goes beyond by connecting the interfaces of these disciplines. This work engages the expertise of a multidisciplinary research team to collate and review the latest knowledge and developments in this exciting research field. The evolutionary perspective of cancer has gained significant international recognition and interest, which is fully understandable given that somatic cellular selection and evolution are elegant explanations for carcinogenesis. Cancer is now generally accepted to be an evolutionary and ecological process with complex interactions between tumor cells and their environment sharing many similarities with organismal evolution. As a critical contribution to this field of research the book is important and relevant for the applications of evolutionary biology to understand the origin of cancers, to control neoplastic progression, and to prevent therapeutic failures.

Is it possible to omit parasites when studying free-living organisms? The answer is clearly no! Parasites have evolved independently in numerous animal lineages, and now make up a considerable proportion of the biodiversity of life. Ecologists, epidemiologists, conservationists and evolutionary biologists are increasingly aware of the universal significance of parasites to the study of ecology and evolution where they have become a powerful model system. This book provides a summary of the issues involved as well as an overview of the possibilities offered by this research topic including the practical applications for disease prevention. It uses well-documented case-studies across a range of scales to illustrate the main trends and prospects in this area, outlining areas for future research.
Ecology and Evolution of Parasitism is the first book to provide a broad synthesis of both the roles and consequences of pathogens on the ecology and evolution of free living systems. It focuses on hosts rather than the parasites themselves, integrating those aspects related to the ecology and the evolution of free-living species (sexual selection, behaviour, life history traits, regulation of populations etc.). The book includes examples across a range of scales from individuals to populations, communities and ecosystems.

Parasites that manipulate the behaviour of their hosts represent striking examples of adaptation by natural selection. This field of study is now moving beyond its descriptive phase and into more exciting areas where the processes and patterns of such dramatic adaptations can be better understood. This innovative text provides an up-to-date, authoritative, and challenging review of host manipulation by parasites that assesses the current state of developments in the field and lays out a framework for future research. It also promotes a greater integration of behavioral ecology with studies of host manipulation (behavioral ecology has tended to concentrate mainly on behaviour expressed by free living organisms and is far less focused on the role of parasites in shaping behaviour). To help achieve this, the editors adopt a novel approach of having a prominent expert on behavioral ecology (but who does not work directly on parasites) to provide an afterword to each chapter.

For several years there has been a growing interest in understanding the dynamics of parasites in ecosystems, as well as the diversity of ways in which they influence ecosystem functioning through their effects on host populations and communities. Ecologists, epidemiologists, evolutionary biologists, and other scientists are increasingly coming to realise that parasites must be taken into account when studying ecosystems. Parasitism and Ecosystems summarizes current knowledge on this topic, providing a comprehensive overview for researchers and students. It represents the first synthesis of both the roles and the consequences of pathogens in ecosystems, utilizing well-documented case-studies to illustrate the main issues as well as identifying prospects for future research.
