Book Description
Leaf longevity is a fundamental process underlying patterns of variation in foliar phenology and determining the distinction between deciduous and evergreen plant species. Variation in leaf longevity is associated with a wide array of differences in the physiology, anatomy, morphology and ecology of plants. This book brings together for the first time information scattered widely in the botanical literature to provide a clear and comprehensive introduction to the nature and significance of variation in leaf longevity. It traces the development of ideas about leaf longevity from the earliest descriptive studies to contemporary theory of leaf longevity as a key element in the function of leaves as photosynthetic organs. An understanding of variation in leaf longevity reveals much about the nature of adaptation at the whole plant level and provides fundamental insights into the basis of variation in plant productivity at the ecosystem level. The analysis of leaf longevity also provides a process-based perspective on phenological shifts associated with the changing climate. Readers will find this an informative synthesis summarizing and illustrating different views in a readily accessible narrative that draws attention to a central but too often unappreciated aspect of plant biology. The nature and causes of seasonal patterns in the birth and death of individual plant leaves are essential to the understanding of the health of plant communities, biomes, and consequently our planet.

Book Description
In the course of evolution, a great variety of root systems have learned to overcome the many physical, biochemical and biological problems brought about by soil. This development has made them a fascinating object of scientific study. This volume gives an overview of how roots have adapted to the soil environment and which roles they play in the soil ecosystem. The text describes the form and function of roots, their temporal and spatial distribution, and their turnover rate in various ecosystems. Subsequently, a physiological background is provided for basic functions, such as carbon acquisition, water and solute movement, and for their responses to three major abiotic stresses, i.e. hard soil structure, drought and flooding. The volume concludes with the interactions of roots with other organisms of the complex soil ecosystem, including symbiosis, competition, and the function of roots as a food source.

Book Description
The last 30 years has seen the development of increasingly sophisticated models that quantify canopy carbon exchange. These models are now essential parts of larger models for prediction and simulation of crop production, climate change, and regional and global carbon dynamics. There is thus an urgent need for increasing expertise in developing, use and understanding of these models. This in turn calls for an advanced, yet easily accessible textbook that summarizes the “canopy science” and introduces the present and the future scientists to the theoretical background of the current canopy models. This book presents current knowledge of functioning of plant canopies, models and strategies employed to simulate canopy function, and the significance of canopy architecture, physiology and dynamics in ecosystems, landscape and biosphere.

Book Description
Most eucalypts grow naturally on soils low in fertility. Commercial plantations of eucalypts have been established around the world over a range of climates and soils. These two themes are central to this book. Nutrition of Eucalypts provides a comprehensive survey of nutritional ecology of eucalypts in their natural environment and in plantations. The authors, who are all at the forefront of research and development in their fields, are from the various eucalypt growing regions including Brazil, India, China, Spain and Australia. Their text aims at a state-of-the-art presentation. The book includes a key and descriptions for recognising nutrient deficiencies in eucalypts.
