Описание: This book presents a detailed discussion on the direct interactions of plants and microorganisms in the rhizosphere environment.
Описание: This volume reviews our current knowledge and novel research areas on Pochonia chlamydosporia, a cosmopolitan fungus occurring in soils as a saprophyte yet capable of colonizing the rhizosphere of crops as an endophyte and behaving as a parasite of eggs of plant-parasitic nematodes.

Описание: Papers Presented at a Symposium held May 8--11, 1989, at the Beltsville Agricultural Research Center (BARC), Beltsville, Maryland, U.S.A.
This book focuses on the development of DGT (diffusive gradients in thin films) and the related techniques for measuring and investigating the geochemical process and P transfer across the sediment/water or sediment/root interface in lakes. A series of DGT techniques such as new types of probes, test methods in sediment or the rhizosphere, DIFS (DGT induced fluxes in sediments and soils) model for kinetic P exchange, CID (computer imaging densitometry) for S(-II), and microchelex gel/LA-ICP-MS (laser ablation inductively coupled plasma mass spectrometry) have been developed.
The corresponding chapters on the theory and methodology of DGT, the "internal P loading" or P transfer across sediment/root in two lakes, provide insights into the research method and conclusions, including the P release mechanism, the quantification of "internal P loading", kinetic P exchange in DGT/sediment interface, Fe- or S(-II)-microniches at submillimeter scales in sediments for the prediction of P release, and DGT as a surrogate for the prediction of P uptake by roots.
It also offers new perspectives in the fields of P analysis and P process in micro-interfaces in lakes using DGT techniques. The P remobilization from Fe-bound P, the coupled Fe-S(-II)-P geochemical reaction and algae biomass breakdown causing P release, are elucidated using DGT methods in sediment layers. DGT parameters and curves for time or distance derived from DIFS can be used to assess kinetic P release in the sediment microzone. CID and LA-ICP-MS methods deliver Fe- and S(-II) images at submillimeter scales, which can be used for the quantification of flux related to microniche peaks and the prediction of P release from Fe-microniche or Fe-S(-II)-P geochemical reactions. DGT measurements in-situ in rhizosphere or rhizonbox can give CE (effective concentration) and CDGT values for the prediction of P accumulated in plant tissues.
This book provides a valuable reference resource for senior graduate students, lecturers and researchers in the fields of the geochemical process of eutrophic elements in lakes, lake eutrophication mechanism and environmental analysis.
Описание: An overview of how complex systems from a variety of fields can be modelled using principles of quantum mechanics; from biology and ecology, to sociology and decision-making. The mathematical basis of these models is fully described, providing a self-contained introduction for students and researchers in applied mathematics or theoretical physics.
