Book excerpt: Traditionally, the analysis of soil health has overlooked the biological component of soil due to poor understanding of connections between the microbiome and empirically measured soil health indicators. The purpose of this study was to assess the effects of environmental and anthropogenic stressors on the soil microbiome, with the aim of identifying measurable soil biological indicators. Chosen soils were examined under distinct conditions to evaluate the effect of selected environmental and anthropogenic stressors on the microbiome. Soil biological responses were analyzed via enzymatic response, microbial functional genes, and microbial community. Environmental factors such as soil moisture and organic matter showed significant influence on the microbiome with each selected biological indicator showing importance. Anthropogenic factors provided various responses dependent largely on the nature of the soil amendment. This study demonstrates that in addition to traditional soil health indicators, soil biological indicators should be included in the process of determining healthy soils.

Book excerpt: In this thesis I studied how long-term soil contamination affects microbial populations and processes, ecosystem properties and functional stability. I also investigated which parameters are suitable as indicators of soil quality in long-term contaminated soils. I found that contamination had a negative impact on many examined microbial parameters, e.g. biomasses, respiration and growth rate (Chapter 2). Some parameters like protozoan biomass and metabolic quotient did not show any effect of stress probably due to strong variation. No single parameter indicated effects of both stressors. Thus, a set of indicators is needed to assess the condition of contaminated soils. In chapter 3 I tested information indices as a tool to describe ecological succession in belowground ecosystems. I used data from a primary succession on the island of Schiermonnikoog. I found that the indices that describe both size and organization of ecosystem followed trends predicted by the theory, but at the same time they were strongly correlated with total system biomass. Therefore I could not say whether the observed trends reflect succession or simply the build up of biomass. However, analysis of relative indices that are independent of biomass and describe only the organization of the ecosystem, showed that succession occurred only in soils between 0 and 10 years old. Since other authors clearly have shown that there has been succession in these soils in, I conclude that the relative information indices are not sensitive indicators of succession. In contaminated soils, however, relative information indices were sensitive to stress caused by high concentrations of copper and by low pH (chapter 4). Stress affected the organization of belowground ecosystems as predicted by the theory. Stressed soils were more vulnerable to external perturbations and less efficient in processing energy than unstressed soils. As the relative information indices responded to stress in predictable manner and each of them revealed effects of both stresses I concluded that these indices are useful indicators of environmental stress. In contrary the absolute indices responded in unpredicted manner to stress and therefore are not suitable as indicators of stress. In chapters 5 and 6, I used “stress on stress” experiments to test the functional stability of soil respiration and bacterial growth rate to additional stress or disturbance in experimentally contaminated soils. The results described in Chapter 5 seemed to confirm the hypothesis that microbial processes in not-stressed soils are more stable to additional stress. The microbial processes showed different responses to disturbances (Chapter 6) than to stress (Chapter 5). In some cases stressed soils appeared to be more stable to additional disturbance than not-stressed soils, in other cases the opposite was found. In chapter 7, I tested the functional stability in a real field situation with zinc and cadmium pollution. In this experiment processes responded differently than in the former experiments. Probably the response of a process depends on whether a co-tolerance towards a given (subsequent) stress was developed during exposure to the first stress.

Book excerpt: Despite the connections between soils and human health, there has not been a great amount of attention focused on this area when compared to many other fields of scientific and medical study. Soils and Human Health brings together authors from diverse fields with an interest in soils and human health, including soil science, geology, geography, biology, and anthropology to investigate this issue from a number of perspectives. The book includes a soil science primer chapter for readers from other fields, and discusses the ways the soil science community can contribute to improving our understanding of soils and human health. Features Discusses ways the soil science community can contribute to the improvement of soil health Approaches human health from a soils-focused perspective, covering the influence of soil conservation and contact with soil on human health Illustrates topics via case studies including arsenic in groundwater in Bangladesh; the use of Agent Orange in Vietnam; heavy metal contamination in Shipham, United Kingdom and Omaha, Nebraska, USA; and electronic waste recycling in China. In a scientific world where the trend has often been ever-increasing specialization and increasingly difficult communication between fields and subfields, the interdisciplinary nature of soils and human health studies presents a significant challenge going forward. Fields with an interest in soils and human health need to have increased cross-disciplinary communication and cooperation. This book is a step in the direction of accessibility and innovation, elucidating the state of knowledge in the meeting of soil and health sciences, and identifying places where more work is needed.

Available in PDF, EPUB and Kindle. Book excerpt: The globally important nature of wetland ecosystems has led to their increased protection and restoration as well as their use in engineered systems. Underpinning the beneficial functions of wetlands are a unique suite of physical, chemical, and biological processes that regulate elemental cycling in soils and the water column. This book provides an in-depth coverage of these wetland biogeochemical processes related to the cycling of macroelements including carbon, nitrogen, phosphorus, and sulfur, secondary and trace elements, and toxic organic compounds. In this synthesis, the authors combine more than 100 years of experience studying wetlands and biogeochemistry to look inside the black box of elemental transformations in wetland ecosystems. This new edition is updated throughout to include more topics and provide an integrated view of the coupled nature of biogeochemical cycles in wetland systems. The influence of the elemental cycles is discussed at a range of scales in the context of environmental change including climate, sea level rise, and water quality. Frequent examples of key methods and major case studies are also included to help the reader extend the basic theories for application in their own system. Some of the major topics discussed are: Flooded soil and sediment characteristics Aerobic-anaerobic interfaces Redox chemistry in flooded soil and sediment systems Anaerobic microbial metabolism Plant adaptations to reducing conditions Regulators of organic matter decomposition and accretion Major nutrient sources and sinks Greenhouse gas production and emission Elemental flux processes Remediation of contaminated soils and sediments Coupled C-N-P-S processes Consequences of environmental change in wetlands# The book provides the foundation for a basic understanding of key biogeochemical processes and its applications to solve real world problems. It is detailed, but also assists the reader with box inserts, artfully designed diagrams, and summary tables all supported by numerous current references. This book is an excellent resource for senior undergraduates and graduate students studying ecosystem biogeochemistry with a focus in wetlands and aquatic systems.

Book excerpt: This new edition of Numerical Ecology with R guides readers through an applied exploration of the major methods of multivariate data analysis, as seen through the eyes of three ecologists. It provides a bridge between a textbook of numerical ecology and the implementation of this discipline in the R language. The book begins by examining some exploratory approaches. It proceeds logically with the construction of the key building blocks of most methods, i.e. association measures and matrices, and then submits example data to three families of approaches: clustering, ordination and canonical ordination. The last two chapters make use of these methods to explore important and contemporary issues in ecology: the analysis of spatial structures and of community diversity. The aims of methods thus range from descriptive to explanatory and predictive and encompass a wide variety of approaches that should provide readers with an extensive toolbox that can address a wide palette of questions arising in contemporary multivariate ecological analysis. The second edition of this book features a complete revision to the R code and offers improved procedures and more diverse applications of the major methods. It also highlights important changes in the methods and expands upon topics such as multiple correspondence analysis, principal response curves and co-correspondence analysis. New features include the study of relationships between species traits and the environment, and community diversity analysis. This book is aimed at professional researchers, practitioners, graduate students and teachers in ecology, environmental science and engineering, and in related fields such as oceanography, molecular ecology, agriculture and soil science, who already have a background in general and multivariate statistics and wish to apply this knowledge to their data using the R language, as well as people willing to accompany their disciplinary learning with practical applications. People from other fields (e.g. geology, geography, paleoecology, phylogenetics, anthropology, the social and education sciences, etc.) may also benefit from the materials presented in this book. Users are invited to use this book as a teaching companion at the computer. All the necessary data files, the scripts used in the chapters, as well as extra R functions and packages written by the authors of the book, are available online (URL: http://adn.biol.umontreal.ca/~numericalecology/numecolR/).

Available in PDF, EPUB and Kindle. Book excerpt: With regional, national, and global processes affecting both the structure and function of lakes and rivers, assessment methodology must encompass many attributes to evaluate the impact of these processes on water quality. Many of the changes in biological communities correlate to resource exploitation, nonpoint pollutant interactions, and habitat alteration - factors that can be missed by routine chemical sampling. This creates the need for ecologically-based approaches to this problem. Biological monitoring is a fundamental part of an ecologically-based approach. Biological Monitoring of Aquatic Systems brings together contributions by authors recognized as leaders in the development and utilization of biological monitoring techniques for freshwater ecosystems. It provides a conceptual framework for the use of biological monitoring to assess the environmental health of freshwater resources. Biological monitoring is an important part of any water quality assessment program. Biological Monitoring of Aquatic Systems provides you with an understanding of water resources. It includes discussions concerning historical development, ecological basis, experimental design characteristics, case studies, and future concerns. As efforts to maintain and restore the world's water resources intensify, the need to develop accurate methods to assess the health of these resources becomes critical.

Available in PDF, EPUB and Kindle. Book excerpt: Protists are by far the most diverse and abundant eukaryotes in soils. Nevertheless, very little is known about individual representatives, the diversity and community composition and ecological functioning of these important organisms. For instance, soil protists are commonly lumped into a single functional unit, i.e. bacterivores. This work tackles missing knowledge gaps on soil protists and common misconceptions using multi-methodological approaches including cultivation, microcosm experiments and environmental sequencing. In a first part, several new species and genera of amoeboid protists are described showing their immense unknown diversity. In the second part, the enormous complexity of soil protists communities is highlighted using cultivation- and sequence-based approaches. In the third part, the present of diverse mycophagous and nematophagous protists are shown in functional studies on cultivated taxa and their environmental importance supported by sequence-based approaches. This work is just a start for a promising future of soil Protistology that is likely to find other important roles of these diverse organisms.
