Book Description
Life in the Chesapeake Bay is the most important book ever published on America's largest estuary. Since publication of the first edition in 1984, tens of thousands of naturalists, boaters, fishermen, and conservationists have relied on the book's descriptions of the Bay's plants, animals, and diverse habitats. Superbly illustrated and clearly written, this acclaimed guide describes hundreds of plants and animals and their habitats, from diamondback terrapins to blue crabs to hornshell snails. Now in its third edition, the book has been updated with a new gallery of thirty-nine color photographs and dozens of new species descriptions and illustrations. The new edition retains the charm of an engaging classic while adding a decade of new research. This classic guide to the plants and animals of the Chesapeake Bay will appeal to a variety of readers—year-round residents and summer vacationers, professional biologists and amateur scientists, conservationists and sportsmen.

Book Description
The Chesapeake Bay is North America's largest and most biologically diverse estuary, as well as an important commercial and recreational resource. However, excessive amounts of nitrogen, phosphorus, and sediment from human activities and land development have disrupted the ecosystem, causing harmful algae blooms, degraded habitats, and diminished populations of many species of fish and shellfish. In 1983, the Chesapeake Bay Program (CBP) was established, based on a cooperative partnership among the U.S. Environmental Protection Agency (EPA), the state of Maryland, and the commonwealths of Pennsylvania and Virginia, and the District of Columbia, to address the extent, complexity, and sources of pollutants entering the Bay. In 2008, the CBP launched a series of initiatives to increase the transparency of the program and heighten its accountability and in 2009 an executive order injected new energy into the restoration. In addition, as part of the effect to improve the pace of progress and increase accountability in the Bay restoration, a two-year milestone strategy was introduced aimed at reducing overall pollution in the Bay by focusing on incremental, short-term commitments from each of the Bay jurisdictions. The National Research Council (NRC) established the Committee on the Evaluation of Chesapeake Bay Program Implementation for Nutrient Reduction in Improve Water Quality in 2009 in response to a request from the EPA. The committee was charged to assess the framework used by the states and the CBP for tracking nutrient and sediment control practices that are implemented in the Chesapeake Bay watershed and to evaluate the two-year milestone strategy. The committee was also to assess existing adaptive management strategies and to recommend improvements that could help CBP to meet its nutrient and sediment reduction goals. The committee did not attempt to identify every possible strategy that could be implemented but instead focused on approaches that are not being implemented to their full potential or that may have substantial, unrealized potential in the Bay watershed. Because many of these strategies have policy or societal implications that could not be fully evaluated by the committee, the strategies are not prioritized but are offered to encourage further consideration and exploration among the CBP partners and stakeholders.

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
Through theoretical discussion as well as hands-on participatory learning approaches, Thomashow provides concerned citizens, teachers, and students with the tools needed to become reflective environmentalists. Mitchell Thomashow, a preeminent educator, shows how environmental studies can be taught from different perspective, one that is deeply informed by personal reflection. Through theoretical discussion as well as hands-on participatory learning approaches, Thomashow provides concerned citizens, teachers, and students with the tools needed to become reflective environmentalists. What do I know about the place where I live? Where do things come from? How do I connect to the earth? What is my purpose as a human being? These are the questions that Thomashow identifies as being at the heart of environmental education. Developing a profound sense of oneself in relationship to natural and social ecosystems is necessary grounding for the difficult work of environmental advocacy. In this book he provides a clear and accessible guide to the learning experiences that accompany the construction of an "ecological identity": using the direct experience of nature as a framework for personal decisions, professional choices, political action, and spiritual inquiry. Ecological Identity covers the different types of environmental thought and activism (using John Muir, Henry David Thoreau, and Rachel Carson as environmental archetypes, but branching out into ecofeminism and bioregionalism), issues of personal property and consumption, political identity and citizenship, and integrating ecological identity work into environmental studies programs. Each chapter has accompanying learning activities such as the Sense of Place Map, a Community Network Map, and the Political Genogram, most of which can be carried out on an individual basis. Although people from diverse backgrounds become environmental activists and enroll in environmental studies programs, they are rarely encouraged to examine their own history, motivations, and aspirations. Thomashow's approach is to reveal the depth of personal experience that underlies contemporary environmentalism and to explore, interpret, and nurture the learning spaces made possible when people are moved to contemplate their experience of nature.
