      This article reviews literature relating to the Great Barrier Reef (GBR) and aims to assess the current state of knowledge about (1) the "value" of ecosystem services (ES) provided by the GBR and (2) the way in which activities that are carried out in regions adjacent to the GBR affect those values. It finds that most GBR valuation studies have concentrated on a narrow range of ES (e.g., tourism and fishing) and that little is known about other ES or about the social, temporal, and spatial distribution of those services. Just as the reef provides ES to humans and to other ecosystems, so too does the reef receive a variety of ES from adjoining systems (e.g., mangroves). Yet, despite the evidence that the reef's ability to provide ES has been eroded because of recent changes to adjoining ecosystems, little is known about the value of the ES provided by adjoining systems or about the value of recent changes. These information gaps may lead to suboptimal allocations of resource use within multiple realms.

      The Gaia hypothesis, which proposes that Earth's biota and material environment form a self-regulating system, has been influential in conservation biology, but it has not translated into specific guidelines. Proponents of phylogenetics and ecology often claim primacy over the foundations of conservation biology, a debate that has deep roots in philosophy and science. A more recent claim is that conservation efforts should protect evolutionary processes that will allow diversification. Phylogenetics, ecology, and evolution all have legitimate roles in conservation, when viewed in a temporal perspective. Phylogenetic studies identify the bioheritage of past species radiations, ecology preserves the life-support systems for these lineages in the present, and evolutionary processes allow adaptation of these lineages to novel challenges in the future. The concept of temporal domains in conservation (past, present, future) has an appropriate metaphor in the Norse worldview known as the Orlog. In this body of mythology, three sisters tend the tree of life and fend off a dragon gnawing at the roots. The names of these sisters, Urd, Verdandi, and Skuld, translate to Past, Present, and Future. In Viking mythology, the threads of life cannot persist without the cooperation of these sisters. In the science of conservation biology, they represent the handmaidens of Gaia-three scientific disciplines that can succeed only with a spirit of familial cooperation.
