Available in PDF, EPUB and Kindle. Book excerpt: This book reports on developments in Proximal Soil Sensing (PSS) and high resolution digital soil mapping. PSS has become a multidisciplinary area of study that aims to develop field-based techniques for collecting information on the soil from close by, or within, the soil. Amongst others, PSS involves the use of optical, geophysical, electrochemical, mathematical and statistical methods. This volume, suitable for undergraduate course material and postgraduate research, brings together ideas and examples from those developing and using proximal sensors and high resolution digital soil maps for applications such as precision agriculture, soil contamination, archaeology, peri-urban design and high land-value applications, where there is a particular need for high spatial resolution information. The book in particular covers soil sensor sampling, proximal soil sensor development and use, sensor calibrations, prediction methods for large data sets, applications of proximal soil sensing, and high-resolution digital soil mapping. Key themes: soil sensor sampling – soil sensor calibrations – spatial prediction methods – reflectance spectroscopy – electromagnetic induction and electrical resistivity – radar and gamma radiometrics – multi-sensor platforms – high resolution digital soil mapping - applications Raphael A.

Book Synopsis Osmolytes and Plants Acclimation to Changing Environment: Emerging Omics Technologies by : Noushina Iqbal
Download or read book Osmolytes and Plants Acclimation to Changing Environment: Emerging Omics Technologies written by Noushina Iqbal and published by Springer. This book was released on 2015-12-16 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: The continual change in climatic conditions induces a series of adaptations in plants to suit the unfavorable conditions for sustainable agriculture. For sustainable agriculture, it is important to unravel the precise mechanism(s) that disturb the homeostatic equilibrium at cellular and molecular level and also to enhance understanding to build strategies for the tolerance of plants. Osmolytes have long been identified as pivotal abiotic stress busters because of their role in plants in overcoming extremely harsh environmental conditions. This edited compilation attempts to put forth the scattered knowledge on osmolytes and their role in abiotic stress tolerance together and disseminate as a package to deal with the problems of lower productivity under stressful environment. It will enhance the understanding on osmolytes function and bioengineering of plants for abiotic stress tolerance. The book covers very interesting topics dealing with various osmolytes and the mechanistic approach for abiotic stress tolerance to pave the path of agricultural scientists, breeders for developing high yielding sustainable transgenic crops.

Book Synopsis Ecotoxicology in Latin America by : Cristiano V. M. Araújo
Download or read book Ecotoxicology in Latin America written by Cristiano V. M. Araújo and published by . This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Latin America is one of the most diverse but also vulnerable regions in the world that is under continuous anthropogenic pressure due to increasing urban, industrial and agricultural developments. Although there are many research groups studying the impacts caused by those pressures, the results and conclusions obtained by many of them are largely unknown because their studies are mostly published at the local or regional scale. Ecotoxicology in Latin America represents an effort to collect and share research performed in Latin America in the area of ecotoxicology and environmental risk assessment, presenting a collection of relevant and innovative studies focused on the following topics: (i) Contaminant entrance, transportation, distribution and fate; (ii) Environmental risk in freshwater ecosystems; (iii) Ecological risk in coastal zones; (iv) Biomonitoring programs: water, sediment and air; (v) Physiological effects and biomarkers; (vi) Soil ecotoxicology; (vii) Bioaccumulation and human risk; (viii) Toxicity of emerging contaminants; and (ix) Frontiers in Ecotoxicology. This selection of topics aims at covering the most important subjects and applications of ecotoxicology, including classical and novel subjects. Therefore, this book contains chapters related to different environmental compartments prone to contamination (water, sediment, soil and air), to different contamination sources (agriculture, industry, urban discharges and natural emissions), and to multiple biological responses at different organizational levels (individual to ecosystems, including human beings). It is envisioned to have an international projection within and beyond Latin American countries, as it is a great opportunity to increase the networks not only among Latin American research teams working on similar subjects, but also with teams from other regions. The idea of this book was to favour the connection among groups to quickly improve the development of methods and their application in ecotoxicological and environmental risk studies in Latin America. This book will be useful to important sectors of environmental sciences and related areas, and to specific target demographics such as students and researchers acting in environmental studies, and decision-makers (i.e., politicians and environmental organizations). Ecotoxicology in Latin America presents 34 chapters authored by 111 researchers from 12 Latin American countries (Argentina, Brazil, Chile, Colombia, Costa Rica, Cuba, Ecuador, Mexico, Panama, Peru, Uruguay, and Venezuela) and from 6 non-Latin American countries (Austria, Belgium, Italy, Portugal, Spain, and USA).
