At the dawn of the third millennium, dramatic challenges face human civilization everywhere. Relations between human beings and their environment are in peril, with mounting threats to both biological diversity of life on earth and cultural diversity of human communities. The peoples of the Circumpolar Arctic are at the forefront of these challenges and lead the way in seeking meaningful respon…
This book provides an overview of the intricacies of plant communication via volatile chemicals. Plants produce an extraordinarily vast array of chemicals, which provide community members with detailed information about the producer's identity, physiology and phenology. Volatile organic chemicals, either as individual compounds or complex chemical blends, are a communication medium operating be…
Abiotic stresses such as high temperature, low-temperature, drought and salinity limit crop productivity worldwide. Understanding plant responses to these stresses is essential for rational engineering of crop plants. In Arabidopsis, the signal transduction pathways for abiotic stresses, light, several phytohormones and pathogenesis have been elucidated. A significant portion of plant genomes (…
Understanding plant responses to abiotic stresses is central to our ability to predict the impact of global change and environmental pollution on the production of food, feed and forestry. Besides increasing carbon dioxide concentration and rising global temperature, increasingly frequent and severe climatic events (e.g. extended droughts, heat waves, flooding) are expected in the coming decade…
This work presents up-to-date information on chemical, pharmacological, clinical studies and historical uses of common dietary Chinese herbs. A brief chronological review of Chinese literatures on dietary herb uses, with chapters dedicated to each selected dietary herb, and with plant Latin name indices is provided. Examined are the health benefits that have been studied for centuries. A wide r…
This open access multi-authored book presents a 'state of the science' synthesis of knowledge on the biodiversity of Angola, based on sources in peer-reviewed journals, in books and where appropriate, unpublished official reports. The book identifies Angola as one of the most biologically diverse countries in Africa, but notes that its fauna, flora, habitats and the processes that drive the dyn…
This book focuses on early germination, one of maize germplasm most important strategies for adapting to drought-induced stress. Some genotypes have the ability to adapt by either reducing water losses or by increasing water uptake. Drought tolerance is also an adaptive strategy that enables crop plants to maintain their normal physiological processes and deliver higher economical yield despite…
This work provides detailed overviews and offer new insights into the biology, life histories, cultivation, markets, legal protection, chemistry and medical use of Echinacea species. The extensively detailed maps in this text are the most accurate of any produced, based on verified herbarium records. The information on ethnobotanical uses of Echinacea species, and especially E. angustifolia, is…
This book provides an in-depth analysis of one the of most popular medicinal plants—Echinacea a species that is native to only the US and Canada. There are nine Echinacea species and several roots and above-ground portions of these showy wildflowers have been used in herbal medicine as an immune stimulant and to reduce one’s chances of catching a cold. Considerable medical research supports…
