In recent years, parasitologists have learned much about the way in which parasite biochemistry differs from that of free-living organisms. Inside the host, factors such as temperature, oxygen tension, carbon dioxide concentration and pH have important consequences for the biochemistry and physiology of the parasitic organism. Strong selection pressure therefore operates at all stages of a parasite's life cycle. The parasite's adaptational response to this pressure is the subject of this book.

Many multicellular animals do not require oxygen to live but respire anaerobically. Some of these have adapted to hostile environments, such as sulphide rich habitats, others live as parasites within host organisms, while others still can perhaps be said to look back on the early days of life on earth before anaerobic respiration had evolved.

Economy, society, and environment comprise the three main dimensions of sustainable development but too often they are considered separately. This book, by comparison, examines the interaction of the three dimensions in the context of rural systems, embracing a wide range of topics, including globalisation and reregulation in sustainable food production, conservation and sustainability, the development of sustainable rural communities, and sustainable rural-urban interaction. An international team of geographers, drawn from the International Geographical Union's Commission on The...
