The Role of Microflora in Terrestrial Sulfur Cycling,presents the form of S which is most readily available to plants and microorganisms, it is now generally accepted that organic forms of S represent the major S component(s) in most terrestrial ecosystems (Freney.. 1972, Fitzgerald 1978, David.. 1982). Soils generally contain between loo and 250 of t

The Role of Microfloral and Faunal Interactions in Affecting Soil Processes,hysical, chemical and biotic regimes both buffer and constrain the ongoing nutrient transformations. Using conceptual models and laboratory experiments, a considerable amount of information has been gained about interactions between primary decomposers (bacteria and fungi) and the fauna that feed on

Effects of Management on Soil Decomposers and Decomposition Processes in Grassland, cutting intensity, choice of crops, cultivation practices and use of pesticides directly influence the nutrient supply for the decomposer community by affecting net primary production and how the resultant fixed chemical energy is utilized. Net primary production in grassland sites studied during t

The Role of Modeling in Research on Microfloral and Faunal Interactions in Natural and Agroecosyste7) is more important for our purposes than the particular mathematical tool employed. Explanatory models are structured to be analogous to the real system under study and thus to embody hypotheses about how the real system operates. The structure of correlative models--regression models, for example

Mitchelle on a wide range of topics on polyhedra.Theory of convex po.The focus of this monograph is converting—reshaping—one 3D convex polyhedron to another via an operation the authors call “tailoring.” A convex polyhedron is a gem-like shape composed of flat facets, the focus of study since Plato and Eucl
