Book Description
Entering the Watershed is the product of a two-year project established by the Pacific Rivers Council to develop new federal riverine protection and restoration policy alternatives. It recommends a comprehensive new approach to river protection based on principles of watershed dynamics, ecosystem function, and conservation biology -- a nationwide, strategic community- and ecosystem-based watershed restoration initiative. The book: describes in detail the existing level of damage to rivers and species analyzes flaws and gaps in existing policy provides the framework necessary to develop new policies outlines the scientific underpinnings and management strategies needed in new policy makes specific policy proposals

Book Description
Hypoxia occurs when dissolved oxygen falls below the level necessary to sustain most animal life, often due to fertilizer run-off. This volume reviews how the expanding hypoxic zone in the northern Gulf of Mexico has affected living resources in the Louisiana/Texas shelf. Topics of the 23 chapters include impacts of changing Si/N ratios and phytoplankton species composition, the effect of hypoxia and anoxia on the supply and settlement of benthic invertebrate larvae, and ecological effects of hypoxia in fish, sea turtles, and marine mammals. c.

Book Description
The ongoing growth of human populations within US coastal regions continues to increase habitat loss, eutrophication, organic loading, overfishing, and other anthropogenic stressors in estuarine waters. The National Estuarine Research Reserve System (NERRS) is a federally funded initiative that addresses these critical estuarine problems and coastal resource issues at 25 sites in 21 states. Now estuarine and watershed scientists, resource managers, community planners, and other professionals dealing with coastal zone issues have an expert resource describing the NERRS program, organization, goals, and management strategy. Estuarine Research, Monitoring, and Restoration first defines the components and technical aspects of the NERRS program, then provides valuable insight into the program through the presentation of six case studies of NERRS sites. This book examines estuarine problems including degraded water quality, reduction of biodiversity, and problematic invasive species, then analyzes the human impacts affecting estuaries. The comprehensive analysis of the six estuarine reserve locations characterizes each region's physical, chemical, and biological conditions from the perspective of the NERRS program. These case studies include a cross section of sites from three coasts, each study emphasizing the importance of unified efforts of government and citizens to successfully maintain the ecology of these critical areas.
