Book Description
Microbiome Under Changing Climate: Implications and Solutions presents the latest biotechnological interventions for the judicious use of microbes to ensure optimal agricultural yield. Summarizing aspects of vulnerability, adaptation and amelioration of climate impact, this book provides an important resource for understanding microbes, plants and soil in pursuit of sustainable agriculture and improved food security. It emphasizes the interaction between climate and soil microbes and their potential role in promoting advanced sustainable agricultural solutions, focusing on current research designed to use beneficial microbes such as plant growth promoting microorganisms, fungi, endophytic microbes, and more. Changes in climatic conditions influence all factors of the agricultural ecosystem, including adversely impacting yield both in terms of quantity and nutritional quality. In order to develop resilience against climatic changes, it is increasingly important to understand the effect on the native micro-flora, including the distribution of methanogens and methanotrophs, nutrient content and microbial biomass, among others. - Demonstrates the impact of climate change on secondary metabolites of plants and potential responses - Incorporates insights on microflora of inhabitant soil - Explores mitigation processes and their modulation by sustainable methods - Highlights the role of microbial technologies in agricultural sustainability

Book Description
Understanding the effects climate change will have on the structure and function of global ecosystems is a pressing ecological and social issue. Global change driven changes in atmospheric warming and precipitation régimes have begun to alter the distribution of plants and animals in, as well as the function of, ecosystems. Using two large-scale climate change manipulations, I assessed the effect of changing precipitation and temperature regimes on soil microbial community structure and function. Soil microbial communities regulate decomposition and nutrient cycling rates in ecosystems, thus understanding their response to climatic changes will enable scientists to better predict carbon feedbacks to the atmosphere as well as functional shifts within ecosystems. My first two chapters took advantage of a large-scale precipitation manipulation in a semi-arid woodland. My first chapter aimed to understand how changing precipitation amounts altered the structure and abundance of soil bacteria and fungi; while my second chapter measured how changing precipitation altered soil nitrogen cycling. Overall, I found that soil microbial community composition and function were responsive to changes in precipitation, but these responses were contingent upon seasonal variability in precipitation and the aboveground plant community. My final experiment examined how changing temperature altered soil microbial community structure and function in two temperate forests. Using a large scale warming experiment at two locations, I examined how changes in temperature altered microbial composition, abundance, potential enzyme activity, and decomposition. I found that the effects of warming were contingent upon location; microbial community composition responded to alterations in soil temperature and soil moisture at the warmer site, but not at the cooler site. Unexpectedly, the change in microbial community composition did not result in changes in the rate of decomposition. I conclude that the soil is relatively buffered from atmospheric warming thus changes in microbial community structure and function may take longer than a few years to develop. Taken together, my research demonstrates that understanding the effects of climate change on microbial community structure and function is complex and contingent upon the background abiotic and biotic variability within an ecosystem.

Book Description
In terrestrial ecosystems, soil microorganisms and soil animals are essential for litter degradation, soil formation and the availability of nutrients and trace elements. The measurement of biological soil parameters allows a rapid evaluation of the effects of chemical and physical influences due to pollutants or soil management. This book introduces a number of well proved methods for the analysis of carbon, nitrogen, phosphorus and sulfur cycles. It focuses further on the determination of the number and biomass of microorganisms, algae and animals in the soil. Particular emphasis is placed on the comprehensible and complete description of the experimental procedures.

Book Description
There can be little doubt that there are truly colossal challenges associated with providing food, fibre and energy for an expanding world population without further accelerating already rapid rates of biodiversity loss and undermining the ecosystem processes on which we all depend. These challenges are further complicated by rapid changes in climate and its additional direct impacts on agriculture, biodiversity and ecological processes. There are many different viewpoints about the best way to deal with the myriad issues associated with land use intensification and this book canvasses a number of these from different parts of the tropical and temperate world. Chapters focus on whether science can suggest new and improved approaches to reducing the conflict between productive land use and biodiversity conservation. Who should read this book? Policy makers in regional, state and federal governments, as well as scientists and the interested lay public.

Book Description
This book highlights the impact of climate change on the soil microbiome and its subsequent effects on plant health, soil-plant dynamics, and the ecosphere. It also discusses emerging ideas to counteract these effects, e.g., through agricultural applications of functional microbes, to ensure a sustainable ecosystem. Climate change is altering the soil microbiome distributions and thus the interactions in microbiome and plant‐soil microorganism. Improvement of our understanding of microbe-microbe and plant-microbe interaction under changing climatic conditions is essential, because the overall impact of these interactions under varying adverse environmental conditions is lacking. This book has been designed to understand the impact of climate change, i.e., mainly salt and drought stress, on the soil microbiome and its impact on plant, yield, and the ecosphere. The book is organized into four parts: The first part reviews the impact of climate change on the diversity and richness of the soil microbiome. The second part addresses effects of climate change on plant health. The third part discusses effects on soil-plant dynamics and functionality, e.g., soil productivity. The final part deals with the effects of climate change on ecosystem functioning and also discusses potential solutions. The book will appeal to students and researchers working in the area of soil science, agriculture, molecular biology, plant physiology, and biotechnology.

Book Description
This book provides an enlightening picture of the role of microbes for sustaining life systems and how climatic factors will change the course of the processes. Climate Change and Microbes: Impacts and Vulnerability explores the little-addressed issue of the effects of climate change on microbial ecosystems and the influence of climate change on microbiome diversity across various habitats and regions. Recent years have seen the evidence that microbial communities are neither immune to disruption nor do they have the capacity to recover completely after a stressful climate event. This volume documents the important role of microorganisms as climate engineers and considers mitigation and adaptation strategies as well. It goes on to present the research that addresses a diverse array of topics on the impact of climate change on plant-microbe interactions and microbial aquatic life and change-induced aggravations in microbial populations and processes. The book also addresses microbial foodborne diseases resulting from challenging climates. Other topics include algae as indicators of climate change and strategies for facilitating sustainable agro-ecosystems. This book will be immensely helpful in the study of plant microbiology, agricultural sciences, biotechnology, climate science, and environmental microbiology. It will also be applicable to the field of microbial biotechnology, agricultural, and other life and environmental sciences.
