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.

This book covers a wide range of topics such as role of microorganisms in the global carbon cycle, the impact of climate change on microbial communities, and the feedback mechanism between them. Microorganisms produce and consume greenhouse gases to transform essential elements, such as carbon and nitrogen, to form their cellular components. Microorganisms are also involved in nitrogen and phosphorus cycling, which are essential for plant growth and productivity. Thus, the role of microbial communities in agroecosystems with biogeochemical cycles is imperative for addressing the current global warming situation. Microorganisms are highly sensitive to changes in environmental conditions such as temperature, moisture, and nutrient availability. As the climate continues to change, shifts in microbial community structure and function may have significant consequences for ecosystem services such as nutrient cycling, water purification, and carbon sequestration. In this book experts from a range of fields, such as microbiology, ecology, biogeochemistry, and climate science come together to provide a holistic perspective on the role of microorganisms in climate change. This book is of reference to policymakers, educators, researchers and students working in the field of microbiology and climate sciences.

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.

Rock surfaces provide a challenging habitat for a broad diversity of micro- or small-sized organisms. They interact with each other forming complex communities as well with their substrate causing biodeterioration of rock. Extreme fluctuation in light, temperature and hydration are the main factors that determine the rock surface habitats. The habitat includes epilithic organisms which thrive on the surface without penetrating the rock, endolithic organisms which live just beneath the surface using a thin layer of the rock surface for protection against adverse conditions of the environment (e.g. light protection, storage of water) and chasmo-endolithic organisms which use fractures of the rock surface for a more habitable environment. The book will provide an overview of the various organismal groups, from prokaryotes to vascular plants and arthropods, as well as survey organism-mediated interactions with the rock surface. The latter include biogenic weathering (biogeochemistry, state-of-the art imaging methods), photosynthesis and nitrogen fixation at and inside the rock surface.

This book offers insights into the educational dimensions of climate change and promotes measures to improve education in this context. It is widely believed that education can play a key role in finding global solutions to many problems related to climate change. Indeed, education as a process not only helps young people to better understand and address the impact of global warming, but also fosters better attitudes and behaviours to aid efforts towards mitigating climate change and adapting to a changing environment. But despite the central importance of education in relation to climate change, there is a paucity of publications on this theme. Against this background, the book focuses on the educational aspects of climate change and showcases examples of research, projects and other initiatives aimed at educating various audiences. It also provides a platform for reflections on the role education can play in fostering awareness on a changing climate. Presenting a wide range of valuable lessons learned, which can be adapted and replicated elsewhere, the book appeals to educators and practitioners alike.
