Integrating and Applying Science: A handbook for effective coastal ecosystem assessment

Longstaff BJ, Carruthers TJB, Dennison WC, Lookingbill TR, Hawkey JM, Thomas JE, Wicks EC, Woerner J ·
10 May 2010

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. Establishing and running an effective assessment program is a complex process that necessitates strategic collaboration and partnerships between many individuals and agencies.

Chapter 1: Environmental campaigns: achieving a shared vision using research, monitoring, and management

Dennison WC and Wicks EC ·
2010

A coastal assessment program cannot simply draw from a few individuals; it takes contributions from an entire community and the creation of a shared vision. Keeping a balance among research, monitoring, and management is especially important and includes the dynamics of human interactions and strong communication between stakeholders and the broader community.

Chapter 2: Environmental leadership: achieving a sustainable future by fostering environmental champions

Dennison WC and Thomas JE ·
2010

For every environmental campaign, a strong leader is needed for guidance and motivation. There have been a series of leaders or "champions" in the history of the world who have changed life on this planet. All of these leaders, no matter what area their specialty, have contained the following traits: knowledge of their field; passion for what they do; and an ability to successfully communicate their messages not only to their colleagues, but also to the broader community.

Chapter 4: Communication strategy: packaging and delivering the message for maximum impact

Conner CS, Dennison WC, and Thomas JE ·
2010

Drawing from the last chapter and its emphasis on the importance of communication, this chapter discusses ways to broadcast a message internally within a coastal assessment program and externally to the general public. Throughout the chapter, the steps involved in broadcasting the message (such as determining target audience, ways in which to relay the message, and how to create an appropriate timeline) will be explained in detail.

Chapter 5: Ecological indicators: assessing ecosystem health using metrics

Wicks EC, Longstaff BJ, Fertig BM, and Dennison WC ·
2010

Chapter 4 discussed how selecting an appropriate communication product can affect an audience and persuade opinions. This chapter discusses how using another tool, an indicator (Figure 5.1), not only can persuade opinions, but also can be used to evaluate the health of an ecosystem.

Chapter 7: Ecological forecasts: building a predictive capacity to guide management

Jasinski DA, Longstaff BJ, and Wicks EC ·
2010

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.

Eastern oyster (Crassostrea virginica) [delta]15N as a bioindicator of nitrogen sources: Observations and modeling

Fertig BM, Carruthers TJB, Dennison WC, Fertig EJ, and Altabet MA ·
2010

Stable nitrogen isotopes ([delta]15N) in bioindicators are increasingly employed to identify nitrogen sources in many ecosystems and biological characteristics of the eastern oyster (Crassostrea virginica) make it an appropriate species for this purpose. To assess nitrogen isotopic fractionation associated with assimilation and baseline variations in oyster mantle, gill, and muscle tissue [delta]15N, manipulative fieldwork in Chesapeake Bay and corresponding modeling exercises were conducted.

Integrating and Applying Science: A practical handbook for effective coastal ecosystem assessment

Longstaff BJ, Carruthers TJB, Dennison WC, Lookingbill TR, Hawkey JM, Thomas JE, Wicks EC, and Woerner JL (eds) ·
2010

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.
