In the course of evolution, a great variety of root systems have learned to overcome the many physical, biochemical and biological problems brought about by soil. This development has made them a fascinating object of scientific study. This volume gives an overview of how roots have adapted to the soil environment and which roles they play in the soil ecosystem. The text describes the form and function of roots, their temporal and spatial distribution, and their turnover rate in various ecosystems. Subsequently, a physiological background is provided for basic functions, such as carbon acquisition, water and solute movement, and for their responses to three major abiotic stresses, i.e. hard soil structure, drought and flooding. The volume concludes with the interactions of roots with other organisms of the complex soil ecosystem, including symbiosis, competition, and the function of roots as a food source.

Motivated by a deeply rooted sense of place and community, Appalachian women have long fought against the damaging effects of industrialization. In this collection of interviews, sociologist Shannon Elizabeth Bell presents the voices of twelve Central Appalachian women, environmental justice activists fighting against mountaintop removal mining and its devastating effects on public health, regional ecology, and community well-being. Each woman narrates her own personal story of injustice and tells how that experience led her to activism. The interviews--many of them illustrated by the women's "photostories"--describe obstacles, losses, and tragedies. But they also tell of new communities and personal transformations catalyzed through activism. Bell supplements each narrative with careful notes that aid the reader while amplifying the power and flow of the activists' stories. Bell's analysis outlines the relationship between Appalachian women's activism and the gendered responsibilities they feel within their families and communities. Ultimately, Bell argues that these women draw upon a broader "protector identity" that both encompasses and extends the identity of motherhood that has often been associated with grassroots women's activism. As protectors, the women challenge dominant Appalachian gender expectations and guard not only their families but also their homeplaces, their communities, their heritage, and the endangered mountains that surround them. 30% of the proceeds from the sale of this book will be donated to organizations fighting for environmental justice in Central Appalachia.

In the United States, some populations suffer from far greater disparities in health than others. Those disparities are caused not only by fundamental differences in health status across segments of the population, but also because of inequities in factors that impact health status, so-called determinants of health. Only part of an individual's health status depends on his or her behavior and choice; community-wide problems like poverty, unemployment, poor education, inadequate housing, poor public transportation, interpersonal violence, and decaying neighborhoods also contribute to health inequities, as well as the historic and ongoing interplay of structures, policies, and norms that shape lives. When these factors are not optimal in a community, it does not mean they are intractable: such inequities can be mitigated by social policies that can shape health in powerful ways. Communities in Action: Pathways to Health Equity seeks to delineate the causes of and the solutions to health inequities in the United States. This report focuses on what communities can do to promote health equity, what actions are needed by the many and varied stakeholders that are part of communities or support them, as well as the root causes and structural barriers that need to be overcome.

This book traces the interacting histories of the disciplines of ecology and economics, from their common origin in the ancient Greek concept of oikonomia, through their distinct encounters with energy physics, to the current obstruction of neoliberal economics to responses to the ecological and climate crisis of the so-called Anthropocene. Reconstructing their constitution as separate sciences in the era of fossil-fuelled industrial capitalism, the book offers an explanation of how the ecological sciences have moved from a position of critical collision with mainstream economics in the 1970s, to one of collusion with the project of permanent growth, in and through the thermal crisis of the biosphere.

The root is the organ that functions as the interface between the plant and the earth environment. Many human management practices involving crops, forests and natural vegetation also affect plant growth through the soil and roots. Understanding the morphology and function of roots from the cellular level to the level of the whole root system is required for both plant production and environmental protection. This book is at the forefront of plant root science (rhizology), catering to professional plant scientists and graduate students. It covers root development, stress physiology, ecology, and associations with microorganisms. The chapters are selected papers originally presented at the 6th Symposium of the International Society of Root Research, where plant biologists, ecologists, soil microbiologists, crop scientists, forestry scientists, and environmental scientists, among others, gathered to discuss current research results and to establish rhizology as a newly integrated research area.

Sacred Ecology examines bodies of knowledge held by indigenous and other rural peoples around the world, and asks how we can learn from this knowledge and ways of knowing. Berkes explores the importance of local and indigenous knowledge as a complement to scientific ecology, and its cultural and political significance for indigenous groups themselves. This third edition further develops the point that traditional knowledge as process, rather than as content, is what we should be examining. It has been updated with about 150 new references, and includes an extensive list of web resources through which instructors can access additional material and further illustrate many of the topics and themes in the book. Winner of the Ecological Society of America's 2014 Sustainability Science Award.
