Coral reefs are the ocean's richest ecosystem in terms of biodiversity and productivity. They are restricted to tropical waters where conditions of salinity, temperature and sedimentation are suitable. Where they grow, their main benthic organisms deposit substantial limestone skeletons, such that they effectively make their own habitat which sustains their dynamic nature and supports the wide range of species which inhabit them. Reefs grow to the low tide level, thus providing a breakwater, but the richest parts lie 5–20 metres below the surface where light is still sufficient but where sediment and turbulence are not severe. Reefs may occur as narrow fringes bordering a continental coast, to huge offshore barriers of corals, to series of atolls that support entire nations; the biogenic nature of corals is enormously important to mankind.Less

Chapter 2, ““And Then We Wept”: Coral Death on Record,” documents the despair side of the pendulum as it contemplates the existing modes and technologies for recording coral bleaching and death. Here, the trajectory is typically of devastation and gloom, as the numbers are depressing at best. Much of the chapter focuses on the third global bleaching event at the Great Barrier Reef, documenting how scientists have both recorded and narrated this event to themselves and to the general public. I examine the role of monitoring in particular, considering whether enhancing scientific knowledge about corals through monitoring is an act of hope, in that it supports conservation action, or one of despair, as it stifles such action and masks the resulting inaction with more and more monitoring. Finally, the chapter shows that even in the world of numbers and maps, “bright spots” and optimistic indexes still rear their more hopeful heads.Less

Popularized by scientists in the 1970s, adaptive management is an integrative, multi-disciplinary approach to managing landscapes and natural resources. Despite its broad appeal many critics complain that adaptive management rarely works in practice as prescribed in theory. This chapter traces the history and evolution of the concept and assess its implementation challenges. One reason adaptive management has not always delivered on its promise to make natural resource management more “rational” is that in the real world of policymaking scientists and natural resource managers must contend with advocates that have conflicting values and goals. Scientists and managers also operate in the context of institutions that create particular constraints and opportunities, and are generally inflexible and resistant to change. In recognition of these sociopolitical realities, the focus of much adaptive management practice and scholarship has shifted to governance, particularly collaboration with stakeholders, transformation of the institutions responsible for management, and the process of social learning.Less

Seven regions are described in terms of their pollution history, other synergistic human pressures, the current challenges and management approaches. Although the timing and detailed impacts vary, primarily for historical reasons, between regions all show similar patterns of change. Sea regions exposed to centuries of human activity (North Sea, Black Sea, Mediterranean Sea and Chesapeake Bay) are considered, as are those for which pollution is more recent (Canadian LOMAs and Coral Sea), and those expected to experience intense pressure in the near future (Arctic Ocean). Nutrients from agriculture and sewage from growing human populations are ubiquitous and not easily managed in marine systems. Controls on industrial discharges have succeeded in halting, sometimes reversing, degradation in some regions (Black Sea, Mediterranean, North Sea, Chesapeake Bay). However, shipping, coastal development and offshore infrastructure continue to apply pressure. While most regions are subject to international agreements and management regimes the effectiveness varies.Less

When a species is threatened with extinction, the loss of value in fact concerns an entire ecosystem that is impoverished or may be threatened with collapse. For the economist, the real difficulty with biodiversity is that a value has to be given to the diversity of life that clearly does not lie in adding up the value of each species, but much more in their multiple interrelationships that provide us with so many services essential for life. The complex issue cannot be evaded if green capital is really to be incorporated into the functioning of the economy.Less

Involvement with the Long-Term Ecological Research (LTER) program has enabled me to ask novel and exciting science questions at larger spatial and longer temporal scales than I could have otherwise. It has enhanced my ability to engage in interdisciplinary collaborative research. The LTER program has afforded my graduate students a variety of opportunities that have enhanced their training and experiences as early career scientists. My undergraduate students learn about LTER research findings in my classes and have the opportunity to work as research assistants in the field and the laboratory. My experiences with LTER- funded research have made me aware of the importance of community and K–12 outreach, and it has provided me opportunities to plan such activities. Engaging in the LTER program has provided me with a myriad of opportunities to collaborate with other sites and groups to address network-level science questions. My collaborators include investigators from within the LTER network, as well as international scientists. My experience in the LTER network began in 2000, when the Santa Barbara Coastal (SBC) LTER project was established, and expanded in 2004 with the founding of the Moorea Coral Reef (MCR) LTER site. I have been a co–principal investigator at both of these sites since their inception. Because I am a marine community ecologist, my research interests and those of my graduate students are closely aligned with the goals and activities of both sites. My LTER network-level experiences include a 3-year term on the LTER Executive Board, participation in several LTER All Scientists Meetings, and a network-sponsored working group on abrupt state shifts. Currently, I am a professor of ecology in the Department of Ecology, Evolution, and Marine Biology at the University of California (UC) Santa Barbara. My disciplinary background is population and community ecology, and prior to my involvement with the LTER program, my research and that of my students focused mainly on questions related to population dynamics and species interactions.
