Plant Litter Quality and Decomposition
by Edited by Georg Cadisch, Ken E Giller
Biological management of nutrient supply to plants is intrinsically more complex than the provision of nutrients as inorganic fertilizers. We need to know whether the nutrients released are retained or lost from the system, whether rates of decomposition can be manipulated to improve nutrient use efficiency, and how the various fractions of plant residues translate into pools of organic matter in soil. Only then can predictive models for nutrient release, plant uptake and soil organic matter dynamics be truly tested and validated. This book brings together contemporary ideas on the characterization and manipulation of plant quality and especially its role in soil organic matter formation and nutrient cycling. It contains work from the leading workers in both temperate and tropical systems. There are also contributions describing work outside decomposition in soil ecosystems, such as the work of plant biochemists and animal nutritionists, as research in these areas has provided many ideas and concepts used in plant quality analysis. A wide range of topics is covered from investigations at the molecular level through to management options for farmers in relation to optimising biological management of crop residues. The work presented in this volume is valuable to all those researching and managing the supply of nutrients to plants. It is important reading for soil scientists, plant physiologists and crop scientists.

BiotechnologyApril 1997Genetic and Environmental Manipulation of Horticultural Crops
by Edited by Ken E Cockshull, D Gray, B Thomas
Genetics has transformed plant pathology on two occasions: first when Mendelian genetics enabled the discovery that disease resistance was a heritable trait in plants, and secondly when Flor proposed the “gene-for-gene” hypothesis to explain his observations of plant-parasite interactions, based on his work on flax rust in North Dakota starting in the 1930s. Our knowledge of the genetics of disease resistance and host-pathogen coevolution is now entering a new phase as a result of the cloning of the first resistance genes. This book provides a broad review of recent developments in this important and expanding subject. Both agricultural and natural host-pathogen situations are addressed. While most of the book focuses on plant pathology, in the usual sense of the term embracing fungal, bacterial and viral pathogens, there is also consideration of parasitic plants and a chapter demonstrating lessons to be learnt from the mammalian immune system. Three overall themes are addressed: genetic analyses and utilization of resistance; population genetics; and cell biology and molecular genetics. Chapters are based on papers presented at the British Society for Plant Pathology Presidential meeting held in December 1995, but all have been revised and updated to mid-1996. Written by leading authorities from North America, Europe and Australia, the book represents an essential update for workers in plant genetics, breeding, biotechnology and pathology.

Dietetics & nutritionApril 2007Encyclopedia of Vitamin E
by Edited by Victor R Preedy, Ronald Watson
Vitamin E is an important dietary constituent which helps in the defence against cellular damage. The process of its absorption from food and its utilisation by the body is an intricate series of reactions. It is also used therapeutically in treating numerous diseases and conditions such as skin damage and the prevention of pathological lesions in major organs, and has been shown to be an important factor in preventing heart disease and cancer. Over 100 chapters from international contributors make this book the most comprehensive reference work in describing both the positive and negative effects and actions of Vitamin E. Chapters are divided into subsections which cover: nomenclature, biochemical, physical and chemical aspects of vitamn E related compounds. Dietary and nutritional influences and effects; cocktails, anti-oxidants mixtures and novel analogues; general physiological systems, metabolism and metabolic stress; brain, neurological and optical systems; reproductive systems, fetus and infant; musculo-skeletal systems and exercise; cardiovascular and pulmonary systems; skin; hepatic, nephrotic and gastrointestinal systems; immune and haematological systems and cancer.

BiotechnologyNovember 1996Biotechnology of Ornamental Plants
by Edited by R L Geneve, John E Preece, Scott A Merkle
Ornamental plants include herbaceous plants produced as bedding plants, greenhouse pot plants and cut flowers, as well as bulbs, trees, shrubs and vines. Ornamental plant production is of major and increasing importance worldwide. Basic scientific research in recent years has provided a better understanding of plant regeneration, genetics, growth and development. This has led to the development of technologies which can significantly improve ornamental species. This book reviews recent advances in the biotechnology of ornamentals. For example, genes have recently been identified for flower characteristics and pest resistance and these have been engineered into ornamental species. The book is divided into four main parts and is written by authors from the USA, UK, Canada, Netherlands, Australia and New Zealand. It is aimed primarily at workers in horticulture and plant biotechnology, but will also be of interest to plant physiologists, geneticists and molecular biologists.

HorticultureApril 2009Mango
Botany, Production and Uses
by Edited by Richard E Litz
The Mango is one of the oldest cultivated fruit crops, having been grown in India for at least 4000 years. Mango is the most important fruit crop of Asia and its annual production is exceeded worldwide only by Musa, citrus, grapes and apples. The last decade has seen a rapid growth of mango production, mainly due to expansion into new growing regions but also to the adoption of modern field practices and cultivars. A wide range of fresh, mango cultivars are now consumed worldwide and are available year round. The Mango: Botany, Production and Uses, published in 1997, represented the first comprehensive examination of all aspects of modern mango production and research. Developing upon the successful first edition, this book incorporates a discussion of significant advances in mango research that have contributed to improved production and will be highly relevant for researchers and growers alike.

Children's & YAA oficina do Cambeva (Cambeva's workshop)
by Lido Loschi
Cambeva's workshop is the first of four books of the collection "Presente de Vô" in partnership with Grupo Ponto de Partida. The book is a mixture of colours and elements that highlight the memory of the world, in which seekers of memories have the mission of bringing light and life to objects found in the travels of two characters: Zalém and Calunga. Cambeva is a restorer who, when the world lost its embrace, tried to reinvent it; he is the grandfather who mends dreams, forgotten things and lost emotions, to whom the seekers ask for help to fix something. In a magical universe, full of children, grandchildren, stories and memories of his lineage of restorers, when faced with this request for restoration, he makes room to bring back an emblematic figure who can no longer sing. A story about memories, care and affection...

EconomicsNovember 2002Persistence and Change in Rural Communities
A Fifty Year Follow-up to Six Classic Studies
by Edited by Albert E Luloff, Richard S Krannich
In the 1930s and 1940s the US Department of Agriculture undertook detailed studies of six US rural communities representing various patterns of social and economic change that were affecting rural America. These studies became classics in the literature on rural communities, and for the past half-century have helped to develop major theoretical perspectives in community sociology.Fifty years later the same study areas were revisited by a team of rural sociologists, with the goal of assessing what changes have occurred and what community characteristics have persisted. This book assesses these changes in rural life."This volume is an important addition to the sociological literature on rural communities."Willis Goudy, The Agricultural History Review, 2003
