Book Description
This volume provides a modern introduction to the soil fauna and their contributions to ecosystem function, the mechanisms that structure soil fauna assemblages from local to global scales, and the potential impacts of global change on soil fauna assemblages and through this ecosystem function. Wanting to be an accessible primer, this book is a high level overview of current knowledge rather than a detailed tome of all existing information, with emphasis being placed on key findings and general patterns. It focuses on the soil fauna but contextualizes these assemblages in relation to the microbial assemblages belowground and the vegetation aboveground. It is clear that our knowledge of soil fauna assemblages is ever increasing, but there is still a lot to discover. Key areas of research are highlighted, with particular reference to the future of soil fauna assemblages.

Book Description
Soil fauna plays a key role in many soil functions, such as organic matter decomposition, humus formation, and nutrient release, modifying soil structure, and improving its fertility. Soil invertebrates play key roles in determining soil suitability for agricultural production and realizing sustainable farming systems. They include an enormous diversity of arthropods, nematodes, and earthworms. However, this fauna suffers from the impact of agricultural activities with implications for the capacity of soil to maintain its fertility and provide ecosystem services. Some agricultural practices may create crucial soil habitat changes, with consequences for invertebrate biodiversity. In the few last decades, especially under intensive and specialized farming systems, a loss in soil ecosystem services has been observed, as a result of the reduction in both the abundance and taxonomic diversity of soil faunal communities. On the other hand, agricultural practices, based on sustainable soil management, can promote useful soil fauna. Therefore, the concerns about the sensibility of soil biota to the agricultural practices make it urgent to develop sustainable management strategies, able to realize favorable microclimate and habitats, and reduce the soil disturbance.

Book Description
Soil fauna plays a significant role at all trophic levels of the soil food web and regulates processes that are crucial for soil functioning, such as nutrient cycling, immobilization and/or degradation of toxic compounds, formation of soil structure, greenhouse gas emissions and C turnover. Although soil fauna is not thought to contribute significantly to soil respiration during litter or soil organic matter (SOM) decomposition, the diversity of soil fauna has been found to strongly influence SOM distribution and dynamics. Yet, the functional contribution of soil fauna to many soil processes is not well understood due to methodological limitations and the high complexity of interactions at various spatiotemporal scales. In general, soil fauna has received far less scientific attention than bacteria and fungi (and lately archaea) in soil studies and has been regularly ignored in global biogeochemical models, with maybe exceptions for some earthworms. However, recent studies are raising the awareness of the influence of soil fauna on ecosystems dynamics. For instance, earthworms have been found to be major players in N2O emissions from soils. They exert a strong influence on C stabilization, and they promote the degradation of polycyclic aromatic hydrocarbons (PAHs). Less studied, ants and termites have been found to increase crop productivity in drylands, and different lifeforms of Collembola have been shown to impact microorganisms in various ways over time, thereby potentially affecting C and N cycles within farming systems. The influence of soil fauna indeed manifests over a broad ranges of spatiotemporal scales. For example, some effect such as aggregate formation may cumulate over time and finally contribute to the formation of whole soil profiles, which serve as a framework for other soil processes such as water movement, decomposition, etc. Meanwhile, soil biodiversity is impacted by an increasing human pressure through deforestation, agriculture intensification, habitat fragmentation or climate change (increasing temperatures, extreme weather events), which leads to soil biodiversity loss, in particular of soil fauna, with associated consequences on soil functioning and resilience.

Book Description
This multi-contributor, international volume synthesizes contributions from the world's leading soil scientists and ecologists, describing cutting-edge research that provides a basis for the maintenance of soil health and sustainability. The book covers these advances from a unique perspective of examining the ecosystem services produced by soil biota across different scales - from biotic interactions at microscales to communities functioning at regional and global scales. The book leads the user towards an understanding of how the sustainability of soils, biodiversity, and ecosystem services can be maintained and how humans, other animals, and ecosystems are dependent on living soils and ecosystem services. This is a valuable reference book for academic libraries and professional ecologists worldwide as a statement of progress in the broad field of soil ecology. It will also be of interest to both upper level undergraduate and graduate students taking courses in soil ecology, as well as academic researchers and professionals in the field requiring an authoritative, balanced, and up-to-date overview of this fast expanding topic.

Book Description
This book presents a detailed discussion on the direct interactions of plants and microorganisms in the rhizosphere environment. It includes fifteen chapters, each focusing on a specific component of plant-microbe interactions, such as the influence of plants on the root microbiome, and the downstream effects of rhizosphere microbial dynamics on carbon and nutrient fluxes in the surroundings. As such, the book helps readers gain a better understanding of diversity above the ground, and its effect on the microbiome and its functionality.

Book Description
About this collection This Collection is the work of more than 50 scientists and Young Reviewers from all around the globe. Our role as editors, together with the authors, was to share our love of soil biodiversity with you. In this Collection, you will discover that soils are full of life. We will introduce some of the methods and techniques used by scientists to observe the life below our feet. We will show you that belowground life is essential to have healthy soils and, therefore, for us. However, you will soon realize that belowground life is changing and under multiple threats. The authors will give ideas on how we can protect soil biodiversity and invite you to actively help us in studying and protecting this valuable ecosystem. We have divided this article Collection into four sections, each of which is introduced below. To make our articles accessible to as many of you as possible, we have created a website hosting translations to languages other than English. Soils are alive Soils are not just rock and dust but are astonishing living systems that are full of life! In this first section, you will read about little creatures that you might already know, like earthworms. You will also discover many new creatures, like springtails and mites, that live close to you in your garden, in the parks, or in nearby fields. Our authors will even show you an entire world of tiny creatures not visible by the naked eye: tiny bacteria, fungi, and protists. Soil biodiversity is about the diversity of these organisms. But how many different organisms are there? How different are they from each other? To answer these questions, scientists need tools and methods to observe and understand the biodiversity under our feet. How can we observe this beautiful world under our feet? In the articles in this section, the authors describe the tools and methods they use to observe and understand soil biodiversity. It is not easy to see the creatures in the soil and what they are doing under our feet; therefore, soils are often called the "black box". Some scientists are using the body fat of soil creatures to identify them and monitor what they feed on; others use DNA to identify soil organisms, like forensic investigators in the movies. In addition, our authors will explain how soil organisms are "talking" to each other and how we study these interactions. What are scientists learning from studying these soil creatures? Is soil biodiversity important to us? Why is soil biodiversity so essential to us? In this section, the authors illustrate that soil biodiversity maintains processes essential for our well-being. For example, you will learn that soil bacteria can keep your food safe by protecting it from diseases. We will highlight that soil biodiversity is essential for nature to work. For example, the authors will demonstrate that soil organisms are vital for recycling dead matter and releasing the nutrients in it. In addition, you will see how soil organisms are directly affecting greenhouse gas emissions such as carbon dioxide and methane by controlling soil processes. Controlling these emissions is critical for keeping our climate stable. Soil organisms are alive, moving, and interacting, but are all these organisms and their important functions changing with time? Are these communities of soil organisms set in stone? Soil communities are changing You probably know that a lot of trees, flowers, and animals can change over the year with the seasons; flowers and fruits appear in spring and summer, leaves drop from the trees in fall. Soil animals are also changing with the seasons. And, like us, soil organisms can move to new places or disappear from others, either permanently or temporarily. These changes can be natural but can also be the result of human activities. Our authors will show you that agricultural practices and the effects of climate change (such as reduced rainfall) are affecting soil organisms, their functions, and the services they provide to us. As we saw previously, soil biodiversity is essential for us, so any changes could be disastrous. So can we protect the organisms in the soil in the same way we protect other organisms such as tigers and pandas? Protecting soil biodiversity In the final section of this Collection, our authors will show you how to protect soil biodiversity. We can reduce our impacts and conserve this wonderful belowground life. But we can even go a step further and restore lost soil functions using our knowledge of soil biodiversity; for example by using fungi to restore soils. However, this is only possible if we understand soil biodiversity and its function. This is where you can help, for example by participating in a citizen science project and going outside to help researchers. Conclusion This Collection is about illuminating the "black box" of soil and showing you some of the fantastic creatures living under our feet. You will learn how scientists are studying soil biodiversity and how this soil biodiversity is essential for us. However, you will also see that soil biodiversity is under threat and needs to be protected. Many people across the globe will be needed to effectively protect these vital systems below our feet. That’s why it is important to spread the word about the beauty and fragility of belowground life. We hope that this Collection will make you a champion of soil biodiversity and that you will pass on this message so that everyone will become more aware of, and be better able to protect soil biodiversity. Now it is your turn to explore and engage with the content of this Collection. We hope there will be something for all of you!
