Book Description
Phosphorus (P) is a finite resource which is essential for life. It is a limiting nutrient in many ecosystems but also a pollutant which can affect biodiversity in terrestrial ecosystems and change the ecology of water bodies. This book collects the latest information on biological processes in soil P cycling, which to date have remained much less understood than physico-chemical processes. The methods section presents spectroscopic techniques and the characterization of microbial P forms, as well as the use of tracers, molecular approaches and modeling of soil-plant systems. The section on processes deals with mycorrhizal symbioses, microbial P solubilization, soil macrofauna, phosphatase enzymes and rhizosphere processes. On the system level, P cycling is examined for grasslands, arctic and alpine soils, forest plantations, tropical forests, and dryland regions. Further, P management with respect to animal production and cropping, and the interactions between global change and P cycling, are treated.

Book Description
The title ‘Phosphorus in Agriculture: 100 % Zero’ is synonymous for make-or-break. And it stands up to the promise. This book sends an important message as it delivers background information, intrinsic hypotheses, validation approaches and legal frameworks, all for balanced phosphorus fertilization in agriculture. This implies firstly that the phosphorus requirement of crop is fully satisfied by applying exclusively fertilizers which contain the nutrient in completely available form. Secondly, environmental demands through eutrophication and hazardous contaminants must not be compromised. The book identifies equally knowledge gaps and deficits in the transformation and implementation of research into practice. Bottom line is that research delivers the tools for a sustainable phosphorus management while legal frameworks are insufficient.

Book Description
Abstract: Useful for biologists, biochemists, medical and dental researchers, other persons interested in mineral metabolism, and biology and medical students, the text provides current knowledge of the physiology of calcium and phosphorus. Topics are: dietary sources of calcium and phosphorus; mechanism of calcium and phosphorus absorption in the intestine--the action of vitamin D; intestinal absorption of calcium and phosphorus data from balance experiments; calcium and phosphorus content of the body; calcium and phosphorus balances and retention; recommended daily calcium and phosphorus requirements; blood calcium and phosphorus; bone formation and resorption; bone; dietary factors on bone and calcium and phosphorus matabolism; action of endocrine glands on bone and calcium and phosphorus metabolism; calcium and phosphorus metabolism of the teeth; excretion of calcium and phosphorous in the urine; kinetic and cybernetic analysis of calcium metabolism; and cellular functions of calcium.

Book Description
This book will provide a complete overview of an alpine ecosystem, based on the long-term research conducted at the Niwot Ridge LTER. There is, at present, no general book on alpine ecology. The alpine ecosystem features conditions near the limits of biological existence, and is a useful laboratory for asking more general ecological questions, because it offers large environmental change over relatively short distances. Factors such as macroclimate, microclimate, soil conditions, biota, and various biological factors change on differing scales, allowing insight into the relative contributions of the different factors on ecological outcomes.
