This second edition of a well-received book focuses on rhythmic behaviour in plants, which regulates all developmental and adaptive responses and can thus be regarded as quintessential to life itself. The chapters provide a timely update on recent advances in this field and comprehensively summarize the current state of knowledge concerning the molecular and physiological mechanisms behind circadian and ultradian oscillations in plants, their physiological implications for growth and development and adaptive responses to a dynamic environment. Written by a diverse group of leading researchers, the book will spark the interest of readers from many branches of science: from physicists and chemists wishing to learn about the multi-faceted rhythms in plants, to biologists and ecologists involved in the state-of-the-art modelling of complex rhythmic phenomena.
Well-known outdoor expert Dave Canterbury offers basic techniques and essential information for primitive wilderness survival in this new heavy-duty pocket guide series from Waterford Press. Perfect for throwing into an overnight pack or brushing up on skills before an expedition, these waterproof, rip-proof guides can be used on their own or in conjunction with one another, similar to the method used in Canterbury's unprecedented Pathfinder System. Covering everything from what to include in a survival kit and improvised tracking techniques to signaling for rescue and building shelter, this collection is ideal for outdoor adventurers of any skill level and provides indispensable wilderness information for all situations.
Useful items needed for short-term situations, such as cordage, containers, fire, or fish poison, as well as plants that address everyday ailments experienced by routine backpackers are included in this handy portable reference to plants found east of the Mississippi River.
Plants are subjected to a variety of abiotic stresses such as drought, temperature, salinity, air pollution, heavy metals, UV radiations, etc. To survive under these harsh conditions plants are equipped with different resistance mechanisms which vary from species to species. Due to the environmental fluctuations agricultural and horticultural crops are often exposed to different environmental stresses leading to decreased yield and problems in the growth and development of the crops. Drought stress has been found to decrease the yield to an alarming rate of some important crops throughout the globe. During last few decades, lots of physiological and molecular works have been conducted under water stress in crop plants.
