Dept of Oceanography, Dalhousie University, Halifax, Nova Scotia, Canada B3H 411. large areas of ocean. Dubinsky Z. Ocean acidification is hypothesized to have a negative impact on coral reef ecosystems, but to understand future potential impacts it is necessary to understand the natural variability and controls of coral reef biogeochemistry. Recent work has extended our understanding of the variation startxref 5, May 7988 Coral Reef Primary Productivity: A Beggar’Banquet s Box I. colonization, epoxy disks were placed at four sites and three habitats (reef base, reef flat, and reef edge). 0000000016 00000 n Click here to explore this opportunity. This approach is sensitive to the number of factors used in the analysis RTCP due to the reef. How coral reefs maintain high diversity and productivity in oligo-trophic tropical oceans often termed – “Darwin’s paradox” re- – mains poorly understood (1–3).

The coral reef food web model used for this study was a previously published, size‐structured model describing predation and production linkages between three trophic groups: predatory fish, herbivorous fish and invertebrates (Rogers et al., 2014).Predators feed in a size‐dependent manner on smaller predators, herbivores and … We use cookies to help provide and enhance our service and tailor content and ads.

Climate change will affect coral reef ecosystems, through sea level rise, changes to the frequency and intensity of tropical storms, and altered ocean circulation patterns. Monitoring is the gathering of data and information on coral reef ecosystems or on those people who use coral reef resources. � �jj�%��Nx�Fī,��f[�C#�����=.�,R�k��-�+'I��aS�2:����4���P��=�R(y���S����>.�t� �_"����*¹��p�����x�%��4�� �u�z2�'KtceQt��A�o1�&Lj�#�#��իz� 0 Coral reefs represent one of the most biodiverse and rich ecosystems. In addition, the relative contribution of coral reefs to RTCP can be specifically evaluated through one of two formulas. Coral Reefs 10, 55-64.

Coral reefs are highly productive ecosystems, with much of this productivity arising from the algal turfs which cover the hard reef substratum. The relative contribution of different plant groups varies pre- dictably along both latitudinal and landward gradients. 0000002574 00000 n endstream endobj 28 0 obj<. Baker J. Carter R.M. Ocean acidification represents a key threat to coral reefs by reducing the calcification rate of framework builders. Reef productivity also responds to relative sea level variations at lower time scales than the Pleistocene, and thus one expects the large frequency variations of sea level oscillations over the Mid‐Pleistocene Transition MPT (Figure 3, after Bintanja & van de Wal, 2008) to significantly impact reef productivity. 1, eds H. A. Lessios and I. G. Macintyre (Panama: Smithsonian Tropical Research Institute), 695–700. 0000001745 00000 n Both pelagic subsidies (2) and internal energy and nutrient cycling (3) have been put forward as drivers of productivity on reefs, but their relative importance is not resolved. Coral reefs are believed by many to have the highest biodiversity of any ecosystem on the planet—even more than a tropical rainforest. show, however, that one of the most striking and important parts of the reef ecosystem is almost never seen (see the Perspective by Riginos and Leis). important sinks for carbon dioxide as corals use carbon to form calcium carbonate 27 0 obj <> endobj %%EOF 0000004183 00000 n Crossland CJ, Hatcher BJ, Smith SV (1991) The role of coral reefs in global carbon production. 0000001590 00000 n �y��Nq��D xref To submit a comment for a journal article, please use the space above and note the following: We use cookies to help provide and enhance our service and tailor content and ads.
