Advances in next generation sequencing technologies, omics, and bioinformatics are revealing a tremendous and unsuspected diversity of microbes, both at a compositional and functional level. Moreover, the expansion of ecological concepts into microbial ecology has greatly advanced our comprehension of the role microbes play in the functioning of ecosystems across a wide range of biomes. Super-imposed on this new information about microbes, their functions and how they are organized, environmental gradients are changing rapidly, largely driven by direct and indirect human activities. In the context of global change, understanding the mechanisms that shape microbial communities is pivotal to predict microbial responses to novel selective forces and their implications at the local as well as global scale. One of the main features of microbial communities is their ability to react to changes in the environment. Thus, many studies have reported changes in the performance and composition of communities along environmental gradients. However, the mechanisms underlying these responses remain unclear. It is assumed that the response of microbes to changes in the environment is mediated by a complex combination of shifts in the physiological properties, single-cell activities, or composition of communities: it may occur by means of physiological adjustments of the taxa present in a community or selecting towards more tolerant/better adapted phylotypes. Knowing whether certain factors trigger one, many, or all mechanisms would greatly increase confidence in predictions of future microbial composition and processes. This Research Topic brings together studies that applied the latest molecular techniques for studying microbial composition and functioning and integrated ecological, biogeochemical and/or modeling approaches to provide a comprehensive and mechanistic perspective of the responses of micro-organisms to environmental changes. This Research Topic presents new findings on environmental parameters influencing microbial communities, the type and magnitude of response and differences in the response among microbial groups, and which collectively deepen our current understanding and knowledge of the underlying mechanisms of microbial structural and functional responses to environmental changes and gradients in both aquatic and terrestrial ecosystems. The body of work has, furthermore, identified many challenges and questions that yet remain to be addressed and new perspectives to follow up on.

Marine environments are fluid. Microorganisms living in the ocean experience diverse environmental changes over wide spatiotemporal scales. For microorganisms and their communities to survive and function in the ocean, they need to have the capacity to sense, respond to, adapt to and/or withstand periodic and sporadic environmental changes. This eBook collates a variety of recent research reports and theoretical discussions on the ecoenergetic strategies, community structure, biogeochemical and ecosystem functions as well as regulatory processes and mechanisms that marine microorganisms employ in response to environmental gradients and variations.

The ongoing global climate change triggered by greenhouse gas growth has had a significant effect on the microbial dynamics of plants and soils. This volume explores the various microbial responses of plants and soils caused directly or indirectly by climate change resulting from rising greenhouse gases and other factors. The book considers the rapidly changing environment and the important role of microbiomes in restoring soil and plant health and in creating sustainable approaches. It discusses the adaptation and mitigation of plants and soils, specifically addressing such topics as biogeochemical processes, antimicrobial resistance, the dynamics of bacteria and fungus in extreme environments, bacterial siderophores for sustainability, and more. The volume also looks at edaphic and regeneration performance of tree species in the temperate forests.

The cryosphere stands for environments where water appears in a frozen form. It includes permafrost, glaciers, ice sheets, and sea ice and is currently more affected by Global Change than most other regions of the Earth. In the cryosphere, limited water availability and subzero temperatures cause extreme conditions for all kind of life which microorganisms can cope with extremely well. The cryosphere’s microbiota displays an unexpectedly large genetic potential, and taxonomic as well as functional diversity which, however, we still only begin to map. Also, microbial communities influence reaction patterns of the cryosphere towards Global Change. Altered patterns of seasonal temperature fluctuations and precipitation are expected in the Arctic and will affect the microbial turnover of soil organic matter (SOM). Activation of nutrients by thawing and increased active layer thickness as well as erosion renders nutrient stocks accessible to microbial activities. Also, glacier melt and retreat stimulate microbial life in turn influencing albedo and surface temperatures. In this context, the functional resilience of microbial communities in the cryosphere is of major interest. Particularly important is the ability of microorganisms and microbial communities to respond to changes in their surroundings by intracellular regulation and population shifts within functional niches, respectively. Research on microbial life exposed to permanent freeze or seasonal freeze-thaw cycles has led to astonishing findings about microbial versatility, adaptation, and diversity. Microorganisms thrive in cold habitats and new sequencing techniques have produced large amounts of genomic, metagenomic, and metatranscriptomic data that allow insights into the fascinating microbial ecology and physiology at low and subzero temperatures. Moreover, some of the frozen ecosystems such as permafrost constitute major global carbon and nitrogen storages, but can also act as sources of the greenhouse gases methane and nitrous oxide. In this book we summarize state of the art knowledge on whether environmental changes are met by a flexible microbial community retaining its function, or if the altered conditions also render the community in a state of altered properties that affect the Earth’s element cycles and climate. This book brings together research on the cryosphere’s microbiota including permafrost, glaciers, and sea ice in Arctic and Antarctic regions. Different spatial scales and levels of complexity are considered, spanning from ecosystem level to pure culture studies of model microbes in the laboratory. It aims to attract a wide range of parties with interest in the effect of climate change and/or low temperatures on microbial nutrient cycling and physiology.

The book provides an overview relevant to various biological mechanisms that regulate carbon exchanges between the major components and their response to climate change. Climate change has a significant impact on people's lives, energy demand, food security, etc. The soil microbial ecology is vital for assessing terrestrial and aquatic carbon cycles and climate feedback. However, the primary concern is the complexity of the soil microbial community and its severely affected functions due to the climate and other global changes. Global warming comprises an assessment of the dynamic interactions and feedback between microbes, plants, and their physical environment due to climate change. The book will address the need to use a multifactor experimental approach to understand how soil microorganisms and their activities adapt to climate change and the implications of carbon cycle feedback. The most pressing concern is a clearer understanding of the biological factors that regulate carbon exchanges between land, oceans, and the atmosphere and how these exchanges will respond to climate change via climate–ecosystem feedbacks, which could augment or quell regional and global climate change. Terrestrial ecosystems play an important role in climate feedback as they produce and absorb greenhouse gases like carbon dioxide, methane, and nitrous oxides. They also strongly contribute to storing enormous amounts of carbon in living vegetation and soils, rendering them a significant global carbon sink. If climate change projections are realistic, such a rapid increase in carbon loss from soil could exacerbate the soil carbon cycle feedback. The book will determine the role of microbial feedback in regulating soil-land-atmosphere carbon exchange under changing climatic conditions at the regional and global levels. The current book will also focus on recent research designed to use beneficial microbes such as plant growth-promoting microorganisms, fungi, endophytic microbes, and others to improve understanding of the interaction and their potential role in promoting advanced management for sustainable agricultural solutions. Understanding the influence on the native microbiome, such as the distribution of methanogens and methanotrophs, nutritional content, microbial biomass, and other factors, is becoming increasingly crucial to establishing climate-resilient agriculture.

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.
