This state-of-knowledge review about the effects of fire on air quality can assist land, fire, and air resource managers with fire and smoke planning, and their efforts to explain to others the science behind fire-related program policies and practices to improve air quality. Chapter topics include air quality regulations and fire; characterization of emissions from fire; the transport, dispersion, and modeling of fire emissions; atmospheric and plume chemistry; air quality impacts of fire; social consequences of air quality impacts; and recommendations for future research.

Unknown to most people, there are innumerable microbial species that accomplish vital ecosystem functions while residing in a suspended state in the troposphere or resting on crop canopies. These microbial species, if utilized properly, can improve agriculture. At the same time, harmful microbes can also devastate crops easily. This new book, Microbiology of the Agricultural Sky, explores a number of microbes present in the agrarian sky and details their identities, roles in nature, and usefulness to crops as well as other biotic factors. The volume first provides an introduction that details the historical aspects of microbes relating to their discovery and identification of their role in agrarian ecosystems. The book then gives detailed explanations of microbes in the atmosphere, with information on the general distribution, spread distance, and intercontinental migration of microbes in the atmosphere. It discusses aeolian dust microbes above agrarian regions and the role of aerial microbes in nutrient dynamics. The book also explains the functions of microbes that reside on crop canopies and the importance of the plant‘s phyllosphere. It looks at microbial flora and how a region‘s bio-geochemical functions affect crops. Also discussed is the role of aerial microbes in inducing epidemics and pandemics among different crops. The final chapter details farm procedures that can be adopted in the outfield and in animal houses and how they impact atmospheric microbes. Key features: Highlights the relevance of the agrarian sky and its microbial component, detailing the wide range of functions that microbes accomplish in the aerospace Presents a timeline of discoveries about aeromicrobiology and the agrarian sky Discusses aerial microbes on crop canopies and their influence on plant pathogens, including beneficial nutrients, need for crop protection, etc. Looks at the microbiology of the agrarian sky and the spread of crop diseases locally and via the intercontinental migration of microbes Discusses farm procedures and their impact on microbes in the troposphere and the agricultural fields beneath it This first-of-its-kind book provides extensive information on microorganisms that can be traced in the agrarian sky and their relevance to agriculture. The easy-to-read style of the book makes it suitable for farmers, agricultural science professors, students, and researchers. It will be useful for farm specialists dealing with airborne diseases, GHG emissions, and agronomic procedures as well.

Completely devoted to applicati on of models to opti mize the use of limited water and nutrients in various climates, this collecti on will inspire confi dence in the capacity of modeling to tackle the biggest threats to secure agriculture. To obtain the most producti on from available water while maintaining natural resources, we need whole system–based quanti tati ve knowledge and tools to help select appropriate crops and manage water and associated inputs on a site-specifi c basis under changing climate. Site-specifi c experimental results are available for limited locati ons, limited periods of ti me, and limited management opti ons. Well-tested process models of cropping systems can extend fi eld research results to long-term weather conditi ons, as well as other climates and soils, allowing us to explore new management opti ons. The case studies in this volume are promising examples of these kinds of soluti ons.

Disturbance ecology continues to be an active area of research, having undergone advances in many areas in recent years. One emerging direction is the increased coupling of physical and ecological processes, in which disturbances are increasingly traced back to mechanisms that cause the disturbances themselves, such as earth surface processes, mesoscale, and larger meteorological processes, and the ecological effects of interest are increasingly physiological. Plant Disturbance Ecology, 2nd Edition encourages movement away from the informal, conceptual approach traditionally used in defining natural disturbances and clearly presents how scientists can use a multitude of approaches in plant disturbance ecology. This edition includes nine revised chapters from the first edition, as well new, more comprehensive chapters on fire disturbance and beaver disturbance. Edited by leading experts in the field, Plant Disturbance Ecology, 2nd Edition is an essential resource for scientists interested in understanding plant disturbance and ecological processes. - Advances understanding of natural disturbances by combining geophysical and ecological processes - Provides a framework for collaboration between geophysical scientists and ecologists studying natural disturbances - Includes fully updated research with 5 new chapters and revision of 11 chapters from the first edition
