This chapter continues the discussion of ecological indicators but with the specific application of producing ecological report cards. It explains the reasons for producing report cards, the steps to produce indicators based on ecological thresholds, and the process of combining indicators into overarching indices. Ecological report cards, like the indicators that they are based on, are one of the most important products for directing data collection and analysis.

This chapter provides an overview of the process of developing, producing, and releasing an ecological forecast, which is supported by statistical analysis and models that underpin forecasts (see Chapters 8 and 9). Areas discussed in this chapter include why you may consider conducting ecological forecasting, some of the essential elements of a forecasting program, and some of the challenges you may face.

One of the most important goals of a coastal assessment program is to increase the knowledge of individuals and agencies who make management decisions. Information must be presented in an easy-to-understand format and supported by quantitative analyses. Quantitative analyses often involve applying statistical techniques that are used to visualize, describe, and model data.

Models can act as an interface among scientists, managers, and the public to build a shared understanding of the status and trends of coastal resources (Figure 9.1). Environmental models can be an effective way of synthesizing large quantities of environmental data. These models can assume a variety of forms and be used to address many different types of research questions.

Vast areas of the globe's coastal zone have experienced significant declines in ecosystem health. Deteriorating water quality, loss and alteration of vital habitats, and reduced populations of fish and shellfish are some of the major changes recorded. Regardless of the differences between cultures, climate regions, and population pressures, integrated management and assessment is required to solve coastal environmental problems.

While engaged in professional oceanographic research and teaching, Marshall, like the postman who goes for a hike on Sundays, spent much of his free time cruising in his 30-foot auxiliary sloop. Underway he realized that, with the equipment readily available on vessels, whether large or small, interested observers could learn a great deal about their surroundings. This prompted him, in his retirement, to write Oceanography: An Observer's Guide.

The environmental challenges now facing humanity are particularly acute in the coastal zone. Research in this region and in other aquatic ecosystems is complicated by interactions that occur over broad scales of time, space, and ecological complexity. Enclosed experimental ecosystems have become critical research tools because they provide a degree of control not achievable through field experiments.

Ratios of nitrogen (N) isotopes in leaves could elucidate underlying patterns of N cycling across ecological gradients. To better understand global-scale patterns of N cycling, we compiled data on foliar N isotope ratios (delta N-15), foliar N concentrations, mycorrhizal type and climate for over 11 000 plants worldwide.

Seagrasses: biology, ecology and conservation, edited by Tony Larkum, Bob Orth and Carlos Duarte, and authored by 79 active seagrass researchers is the most comprehensive book about these unique flowering plants ever written. It is long, 691 pp, with an excess of 100 pages devoted to references, and it includes 26 chapters on evolution, anatomy, biology, physiology, biogeochemistry, remote sensing, grazing and predation, ecology, and management.

This richly illustrated book provides personal accounts derived from interviews with Riverprize recipients over the past 10 years.
