Book Description
Global Integrity Project has brought together leading scientists and thinkers from around the world to examine the combined problems of threatened and unequal human well-being, degradation of the ecosphere, and unsustainable economies. Based on the proposition that healthy, functioning ecosystems are a necessary prerequisite for both economic security and social justice, the project is built around the concept of ecological integrity and its practical implications for policy and management. Ecological Integrity presents a synthesis and findings of the project. Contributors -- including Robert Goodland, James Karr, Orie Loucks, Jack Manno, William Rees, Mark Sagoff, Robert Ulanowicz, Philippe Crabbe, Laura Westra, David Pimentel, Reed Noss, and others -- examine the key elements of ecological integrity and consider what happens when integrity is lost or compromised. The book: examines historical and philosophical foundations of the concept of ecological integrity explores how integrity can be measured examines the relationships among ecological integrity, human health, and food production looks at economic and ethical issues that need to be considered in protecting ecological integrity offers concrete recommendations for reversing ecological degradation while promoting social and economic justice and welfare . Contributors argue that there is an urgent need for rapid and fundamental change in the ecologically destructive patterns of collective human behavior if society is to survive and thrive in coming decades. Ecological Integrity is a groundbreaking book that integrates environmental science, economics, law, and ethics in problem analysis, synthesis, and solution, and is a vital contribution for anyone concerned with interactions between human and planetary health.

Book Description
Report on how mercury (Hg) was examined in top-predator fish, bed sediment, and water from streams that spanned regional and national gradients of Hg source strength and other factors thought to influence methylmercury bioaccum. Sampled settings include stream basins that were agr¿l, urbanized, undeveloped, and mined. Predator fish were targeted for collection, and composited samples of fish were analyzed for total Hg (THg), as most of the Hg found in fish tissue is MeHg. Samples of bed sediment and stream water were analyzed for THg, MeHg, and characteristics thought to affect Hg methylation, such as loss-on-ignition and acid-volatile sulfide in bed sediment, and pH, dissolved organic carbon, and dissolved sulfate in water.

Book Description
From Francis Alÿs and Ursula Biemann to Vivan Sundaram, Allora & Calzadilla, and the Center for Urban Pedagogy, some of the most compelling artists today are engaging with the politics of land use, including the growth of the global economy, climate change, sustainability, Occupy movements, and the privatization of public space. Their work pivots around a set of evolving questions: In what ways is land, formed over the course of geological time, also contemporary and formed by the conditions of the present? How might art contribute to the expansion of spatial and environmental justice? Editors Emily Eliza Scott and Kirsten Swenson bring together a range of international voices and artworks to illuminate this critical mass of practices. One of the first comprehensive treatments of land use in contemporary art, Critical Landscapes skillfully surveys the stakes and concerns of recent land-based practices, outlining the art historical contexts, methodological strategies, and geopolitical phenomena. This cross-disciplinary collection is destined to be an essential reference not only within the fields of art and art history, but also across those of cultural geography, architecture and urban planning, environmental history, and landscape studies.
