Climate change has caused fluctuations in the frequency and severity of droughts and floods, favoring extended periods of drought and extreme rainfall, rises in temperature, and associated with anthropic actions, has triggered other stressful abiotic effects, which have threatened terrestrial ecosystems and, especially agroecosystems. Considering the current environmental scenario, studies related to cultural practices with native or cultivated species have been carried out with the aim of guaranteeing sustainable development, conservation of biodiversity and natural resources, and the guarantee of food sovereignty.
Phytoremediation is the process that uses plants to remove pollutants from soils. These pollutants are stored in the edible parts of plants and, if they are consumed above a certain level, they become a health risk for humans and animals. This book is a critical review of phytoremediation, its direct or indirect effects on food products, and the risks posed by this cost-effective technology in food safety. It shows how different plants are suited for phytoremediation, explains the role of toxicants in the environment, and analyses their effects and risks in the food chain at a global level. It also reviews the extraction methods of toxicants from plants after they are exposed to phytoremedia...
Esta obra tem por objetivo contribuir com a melhor compreensão de características ecofisiológicas do desenvolvimento e anatomia de espécies florestais na região amazônica. Copila resultados interessantes de como algumas espécies florestais respondem à variação de luz em condições ambientes, como dossel superior de florestas, e em simulações ambientais em casa de vegetação. Reunindo uma coletânea de artigos que envolvem respostas fotossintéticas a diferentes níveis de luz em que as folhas se desenvolvem, além de mostrar o desenvolvimento de estruturas anatômicas em condições naturais nos distintos períodos sazonais na região da Amazônia Central. Buscou-se despertar e...
This book is rather unique in its approach and coverage. The approach is essentially that of an engineering textbook, emphasizing the quantitative aspects and highlighting the fundamentals and basic concepts involved. The coverage progresses in a logical and systematic manner from the subcellular, starting with the electrophysiology of the cell membrane, then proceeding to synapses, neurons, and muscle, before considering neuronal motor ensembles and the neuromuscular system as a whole. Simple, clear, and comprehensive explanations are given throughout. After an introductory chapter on some background material in biology, biophysics, and chemical kinetics, a substantial part of the book (Cha...
First published in 1985, this book covers the physiological and environmental factors that regulate leaf growth. It opens with a consideration of the importance to the plant of leaf size, form and development, and then divides naturally into two sections: the first covers the intrinsic factors within the leaf that influence development, including solute and hormonal status, cellular components, and energy transducing systems; the second considers the role of some major environmental variables in the regulation of leaf growth, including temperature, light, water and nutrients, atmospheric influences and the interactive effects of climatic variables.
Nutraceuticals: Efficacy, Safety and Toxicity, Second Edition, brings together everything that is currently known about nutraceuticals and their potential toxic effects. The book introduces readers to nutraceuticals, herbal medicines, Ayurvedic medicines, prebiotics, probiotics, adaptogens, and their uses and specific applications. This essential reference discusses the mechanism of action for the judicious use of these nutraceuticals and the best tools for their evaluation before detailing the safety and toxicity of nutraceuticals and interactions with other therapeutic drugs. Finally, and crucially, regulatory aspects from around the world are covered. Completely revised and updated, this ...
The "Path" to attain liberation ("marga"), a central notion of Buddhist praxis and thought, designates specific patterns of behaviour and methods of practice connected with transformative powers and soteriological goals. This volume shows the plurality and complexity of Buddhist views on the Path found in Buddhist doctrinal, narrative and philosophical literature, epigraphic sources and iconographic programmes from South Asia. Through new analyses-rather than general pictures-of different kinds of sources, this volume examines how the Path was interpreted, discussed and represented in Buddhist traditions of South Asia. It traces the contours of ideologies of the Path that have variously influenced the formation and development of Buddhist identities in the religious and intellectual landscape of premodern South Asia and contributes to revisiting modern descriptions of the Buddhist Path. Contributors are: Naomi Appleton, Malcolm David Eckel, Vincent Eltschinger, Anna Filigenzi, Rupert Gethin, Jowita Kramer, Daniel M. Stuart, Peter-Daniel Szanto, Vincent Tournier and Nobuyoshi Yamabe.
The functional analysis of plant-microbe interactions has re-emerged in the past 10 years due to spectacular advances in integrative study models. This book summarizes basic and technical information related to the plant growth promoting rhizobacteria (PGPR) belonging to the genus Azospirillum, considered to be one of the most representative PGPR last 40 years. We include exhaustive information about the general microbiology of genus Azospirillum, their identification strategies; the evaluation of plant growth promoting mechanisms, inoculants technology and agronomic use of these bacteria and some special references to the genetic technology and use.
Microbes in Land Use Change Management details the various roles of microbial resources in management of land uses and how the microbes can be used for the source of income due to their cultivation for the purpose of biomass and bioenergy production. Using various techniques, the disturbed and marginal lands may also be restored eco-friendly in present era to fulfil the feeding needs of mankind around the globe. Microbes in Land Use Change Management provides standard and up to date information towards the land use change management using various microbial technologies to enhance the productivity of agriculture. Needless to say that Microbes in Land Use Change Management also considers the a...
