Book Description
Estuaries are highly dynamic systems subject to changes occurring over a spectrum of time scales ranging from very short periods (e. g. over a tidal cycle) to geologic time scales. The nature of an estuary reflects complex responses to many driving forces, each having a characteristic frequency (or frequencies) of change. For example, freshwater inflow to estuaries varies daily in response to short-term events such as storms, seasonally, and between years as a result of longer-term climatic variability. Other important components of weather, e. g. wind speed/ direction and daily insolation, also vary over time scales ranging from hours to years. Tidal amplitude changes continuously with dominant frequencies associated with the semi-diurnal cycle, the fortnightly neap-spring, and the semi-annual cycle. Temporal dynamics of these driving forces evoke responses in the form of changing (I) circulation patterns and mixing, (2) sediment composition and transport, (3) solute speciation and distribution, (4) composition and abundance of particulates, (5) biomass, species composition, and productivity of plant and animal communities, (6) rates of material exchange between the sediments, water column, and atmosphere, and (7) bioavailability of trace metals and other pollutants. The purpose of this book is to examine the temporal dynamics of these properties and processes in the San Francisco Bay estuary.

Book Description
"You can't really know the place where you live until you know the shapes and origins of the land around you. To feel truly at home in the Bay Area, read Doris Sloan's intriguing stories of this region's spectacular, quirky landscapes."—Hal Gilliam, author of Weather of the San Francisco Bay Region "This is a fascinating look at some of the world's most complex and engaging geology. I highly recommend this book to anyone interested in an understanding of the beautiful landscape and dynamic geology of the Bay Area."—Mel Erskine, geological consultant "This accessible summary of San Francisco Bay Area geology is particularly timely. We are living in an age where we must deal with our impact on our environment and the impact of the environment on us. Earthquake hazards, and to a lesser extent landslide hazards, are well known, but the public also needs to be aware of other important engineering and environmental impacts and geologic resources. This book will allow Bay Area residents to make more intelligent decisions about the geological issues affecting their lives."—John Wakabayashi, geological consultant

Book Description
Environmental politics and policy, while gaining a significant place in the nation's consciousness, constantly comes up against the United States' desire for more development, more profit, and a collective lack of foresight. Nowhere is this more evident than in the crucial biodiversity of the world's oceans, which are victim to pollution, overharvesting, habitat destruction, and simplistic and fragmented environmental policies that do not speak to underlying problems.Robert Wilder describes how management of the world's oceans and their ecosystems has long faced two principal obstacles. The first is the seemingly infinite capacity of human apathy - something that permits us to take the sea's comfort, sustenance, ecological services, and integrity for granted. The second is the myriad lines for rigid offshore jurisdiction.That people believe the diversity of life on land should be protected is reflected in well-publicized efforts to save the celebrated biodiversity of rainforests. Far less is known, however, about protecting a larger two-thirds of this planet - the oceans. Drawing on academic literature and practical experience, Wilder illustrates the nature of the questions facing decision makers and provides intelligent, well-crafted solutions.By describing how the emerging idea of precautionary action can help build second-generation policy, Wilder offers means to halt problematic overfishing. He integrates political science with the goals of environmental protection, revealing why agencies often fail in their mission to preserve the environment, and offers fresh, sensible, new paths ahead. Wilder shows how damage to marine ecosystems often stems from distant land-based activities and details emerging ideas such as how industrial ecology can be a cost-effective way to preven pollution.Through a rigorous integration of policy and science, Wilder suggests a much-improved second-generation governance of the ocean and coasts and proposes new ideas for resolving the environmental policy stalemate found within the U.S. government.

Book Description
This long-anticipated reference and sourcebook for CaliforniaÕs remarkable ecological abundance provides an integrated assessment of each major ecosystem typeÑits distribution, structure, function, and management. A comprehensive synthesis of our knowledge about this biologically diverse state, Ecosystems of California covers the state from oceans to mountaintops using multiple lenses: past and present, flora and fauna, aquatic and terrestrial, natural and managed. Each chapter evaluates natural processes for a specific ecosystem, describes drivers of change, and discusses how that ecosystem may be altered in the future. This book also explores the drivers of CaliforniaÕs ecological patterns and the history of the stateÕs various ecosystems, outlining how the challenges of climate change and invasive species and opportunities for regulation and stewardship could potentially affect the stateÕs ecosystems. The text explicitly incorporates both human impacts and conservation and restoration efforts and shows how ecosystems support human well-being. Edited by two esteemed ecosystem ecologists and with overviews by leading experts on each ecosystem, this definitive work will be indispensable for natural resource management and conservation professionals as well as for undergraduate or graduate students of CaliforniaÕs environment and curious naturalists.
