Book excerpt: El control de malezas es la gran problemática del cultivo de arroz (Oryza sativa L.) en Chile donde se siembra con semilla pre germinada sobre suelo inundado. Una nueva alternativa de establecimiento del arroz es la siembra en suelo sin lámina de agua, lo que indica la necesidad de nuevos sistemas de control de malezas. Debido a esto, se realizó un ensayo en la localidad de San Carlos (36° 18\U+2019\ 32\U+2019\\U+2019\ S; 71° 58\U+2019\ 26\U+2019\\U+2019\ O) temporada 2013-2014 con el objetivo de realizar una selección preliminar de herbicidas de pre y post emergencia sobre arroz en siembra directa. Para esto, se evaluaron los herbicidas clomazone y pendimetalin de pre emergencia temprana y los herbicidas penoxsulam, bispiribac, cyhalofop, bentazone, MCPA, picloram y triclopyr de post emergencia en arroz cultivar Diamante sembrado el 7 de octubre de 2013. El diseño correspondió a bloques completos al azar con 18 tratamientos y 4 repeticiones en parcelas de 6 m x 3 m. Se evaluó, población y materia seca de arroz a macolla y cosecha del cultivo y densidad de arroz a la macolla y cosecha del cultivo, evaluando además el rendimiento y componentes de rendimiento del arroz desde 2 m2 por parcela. Los resultados indican que los tratamientos que incluyeron penoxsulam fueron los más efectivos, en especial en aplicación secuencial de penoxsulam y cyhalofop en dosis de 40,8 y 270 g ha-1 con rendimiento de 6990 kg ha-1 de arroz.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents a holistic view of the complex and dynamic responses of plants to nanoparticles, the signal transduction mechanisms involved, and the regulation of gene expression. Further, it addresses the phytosynthesis of nanoparticles, the role of nanoparticles in the antioxidant systems of plants and agriculture, the beneficial and harmful effects of nanoparticles on plants, and the application of nanoparticles and nanotubes to mass spectrometry, aiming ultimately at an analysis of the metabolomics of plants. The growing numbers of inventions in the field of nanotechnology are producing novel applications in the fields of biotechnology and agriculture. Nanoparticles have received much attention because of the unique physico-chemical properties of these compounds. In the life sciences, nanoparticles are used as “smart” delivery systems, prompting the Nobel Prize winner P. Ehrlich to refer to these compounds as “magic bullets.” Nanoparticles also play an important role in agriculture as compound fertilizers and nano-pesticides, acting as chemical delivery agents that target molecules to specific cellular organelles in plants. The influence of nanoparticles on plant growth and development, however, remains to be investigated. Lastly, this book reveals the research gaps that must be bridged in the years to come in order to achieve larger goals concerning the applications of nanotechnology in the plants sciences. In the 21st century, nanotechnology has become a rapidly emerging branch of science. In the world of physical sciences, nanotechnological tools have been exploited for a broad range of applications. In recent years, nanoparticles have also proven useful in several branches of the life sciences. In particular, nanotechnology has been employed in drug delivery and related applications in medicine.

Available in PDF, EPUB and Kindle. Book excerpt: Over this last decade, the concept of Social Metabolism has gained prestige as a theoretical instrument for the required analysis, to such an extent that there are now dozens of researchers, hundreds of articles and several books that have adopted and use this concept. However, there is a great deal of variety in terms of definitions and interpretations, as well as different methodologies around this concept, which prevents the consolidation of a unified field of new knowledge. The fundamental aim of the book is to conduct a review of the past and present usage of the concept of social metabolism, its origins and history, as well as the main currents or schools that exist around this concept. At the same time, the reviews and discussions included are used by the authors as starting points to draw conclusions and propose a theory of socio-ecological transformations. The theoretical and methodological innovations of this book include a distinction of two types of metabolic processes: tangible and intangible; the analysis of the social metabolism at different scales (in space and time) and a theory of socio-ecological change overcoming the merely “systemic” or “cybernetic” nature of conventional approaches, giving special protagonism to collective action.

Available in PDF, EPUB and Kindle. Book excerpt: Business-as-usual in terms of industrial and technological development – even if based on a growing fear of pollution and shortages of natural resources – will never deliver sustainable development. However, the growing interest in recent years in the new science of industrial ecology (IE), and the idea that industrial systems should mimic the quasi-cyclical functions of natural ecosystems in an 'industrial food chain', holds promise in addressing not only short-term environmental problems but also the long-term holistic evolution of industrial systems. This possibility requires a number of key conditions to be met, not least the restructuring of our manufacturing and consumer society to reduce the effects of material and energy flows at the very point in history when globalisation is rapidly increasing them. This book sets out to address the theoretical considerations that should be made implicit in future research as well as practical implementation options for industry. The systematic recovery of industrial wastes, the minimisation of losses caused by dispersion, the dematerialisation of the economy, the requirement to decrease our reliance on fuels derived from hydrocarbons and the need for management systems that help foster inter-industry collaboration and networks are among the topics covered. The book is split into four sections. First, the various definitions of IE are outlined. Here, important distinctions are made between industrial metabolism and IE. Second, a number of different industrial sectors, including glass, petroleum and electric power, are assessed with regard to the operationalisation of industrial ecology. Eco-industrial Parks and Networks are also analysed. Third, the options for overcoming obstacles that stand in the way of the closing of cycles such as the separation and screening of materials are considered and, finally, a number of implications for the future are assessed. The contributions to Perspectives on Industrial Ecology come from the leading thinkers working in this field at the crossroads between a number of different disciplines: engineering, ecology, bio-economics, geography, the social sciences and law.

Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the recent advancements in the role of various biomolecules in regulating root growth and development. Rhizobiology is a dynamic sub discipline of plant science which collates investigations from various aspects like physiology, biochemistry, genetic analysis and plant–microbe interactions. The physiology and molecular mechanisms of root development have undergone significant advancements in the last couple of decades. Apart from the already known conventional phytohormones (IAA, GA, cytokinin, ethylene and ABA), certain novel biomolecules have been considered as potential growth regulators or hormones regulating plant growth and development. Root phenotyping and plasticity analysis with respect to the specific functional mutants of each biomolecule shall provide substantial information on the molecular pathways of root signaling. Special emphasis provides insights on the tolerance and modulatory mechanisms of root physiology in response to light burst, ROS generation, agravitrophic response, abiotic stress and biotic interactions.

Available in PDF, EPUB and Kindle. Book excerpt: It is increasingly evident that the conventional scientific approach to economic processes and related sustainability issues is seriously flawed. No economist predicted the current planetary crisis even though the world has now undergone five severe recessions primed by dramatic increases in the price of oil. This book presents the results of more than twenty years of work aimed at developing an alternative method of analysis of the economic process and related sustainability issues: it is possible to perform an integrated and comprehensive analysis of the sustainability of socio-economic systems using indicators and variables that have been so far ignored by conventional economists. The book’s innovative approach aims to provide a better framework with which we can face the predicaments of sustainability issues. It begins by presenting practical examples of the shortcomings of conventional economic analysis and examines the systemic problems faced when trying to use quantitative analysis for governance. In providing a critical appraisal of current applications of economic narratives to the issue of sustainability, the book presents several innovative concepts required to generate a post-Newtonian approach to quantitative analysis in the Musiasem approach. An empirical section illustrates the results of an analysis of structural changes in world and EU countries. Finally, the book, using the insight gained in the theoretical and empirical analysis, exposes the dubious quality of many narratives currently used in the sustainability debate. Overall, the performance of modern economies across different hierarchical levels of organization and across different disciplinary knowledge systems is fully analyzed and a more realistic measure of happiness and well-being is devised. The book should be of interest to researchers and students looking at the issue of sustainability within a variety of disciplines.

Available in PDF, EPUB and Kindle. Book excerpt: Invasive alien species are among today's most daunting environmental threats, costing billions of dollars in economic damages and wreaking havoc on ecosystems around the world. In 1997, a consortium of scientific organizations including SCOPE, IUCN, and CABI developed the Global Invasive Species Programme (GISP) with the explicit objective of providing new tools for understanding and coping with invasive alien species. Invasive Alien Species is the final report of GISP's first phase of operation, 1997-2000, in which authorities from more than thirty countries worked to examine invasions as a worldwide environmental hazard. The book brings together the world's leading scientists and researchers involved with invasive alien species to offer a comprehensive summary and synthesis of the current state of knowledge on the subject. Invasive alien species represent a critical threat to natural ecosystems and native biodiversity, as well as to human economic vitality and health. The knowledge gained to date in understanding and combating invasive alien species can form a useful basis on which to build strategies for controlling or minimizing the effects in the future. Invasive Alien Species is an essential reference for the international community of investigators concerned with biological invasions.
