Coral morphology, diversity and reef growth

  title={Coral morphology, diversity and reef growth},
  author={John Chappell},
The shape of reef corals is affected by light level1,2 and by wave stress3,4, leading to the well-known zonation of coral form associations with exposure and depth3–6. Growth form also seems to be constrained by geometric factors2,7,8. Similarly, coral calcification rate, of importance both for coral form and for net reef growth, is light dependant9,10, and may be affected by other factors such as wave stress and sediment flux. Here the growth structure of raised Pleistocene reefs in New Guinea… Expand
Responses of coral reefs and reef organisms to sedimentation
Data is needed on the threshold levels for reef orgarusms and for the reef ecosystem as a whole the levels above which sedimentation has lethal effects for particular species and above which normal functioning of the reef ceases. Expand
Growth potential of coral reefs and carbonate platforms
Growth rates of massive colonies of Montastrea annularis from Curactao, Netherlands Antilles, were related to light extinction profiles to evaluate the role oflight in growth. The observed decreaseExpand
Corals and reefs as indicators of paleo-sea levels with special reference to the Great Barrier Reef
Coral reefs are built by and contain a large range of plants and animals, many of which have a specific relationship to sea level. However, the main framework builders, scleractinian corals, have aExpand
The Growth Rate of Coral Porites Lutea Relating to the El Niño Phenomena at Tunda Island, Banten Bay, Indonesia☆
Abstract Reefs are benthic biotas that have an important role in marine ecosystems, where its growth is strongly influenced by environmental conditions. A massive coral has capacity to recordsExpand
Adaptation and Diversity of Reef Corals
oral reefs are the most complex and diverse communities in the sea, and they are in both respects more similar to tropical rain forests than is any other marine ecosystem. Why coral reefs andExpand
10.13 Coral Systems
Coral reefs are globally unique landforms formed in the tropical ocean from the interaction between ecological and physical processes. Reefs are also among the most valuable ecosystems on the Earth,Expand
The shapes of Paleozoic and modern reef-builders: a critical review
Paleoecologists studying Paleozoic reef-builders have interpreted their growth forms as responses to conditions of depth and turbulence in reef complexes. Comparison of the shapes of PaleozoicExpand
Terrigenous sedimentation and coral reef growth: a conceptual framework
Abstract The role of terrigenous (and non-framework carbonate) sedimentation has not been prominent in models of coral reef growth and evolution. We derive and discuss a semi-quantitative model whichExpand
Morphological responses of a cup coral to environmental gradients
The morphology of the cup coral Caryophyllia smithii was studied under different regimes of water movement at Lough Hyne, County Cork, Ireland and an increased coral height for any given calyx width was found with increasing depth at sheltered sites and was higher at all depths than at the wave exposed site (even though actual heights decreased).

Coral reefs and growth dynamics of a low-angle Carboniferous platform: Records from Tianlin, southern China
Abstract Metazoan reef building receded globally during the Carboniferous after the Late Devonian extinction events. Shallow-water bioconstructions were generally small and scarce, and corals playedExpand


A method of counting chain links covering living coral is described and discussed as a means of calculating species diversity on coral reefs. Species diversity on San Blas coral reefs, AtlanticExpand

Competition can be shown to occur between two species when the removal or thinning of one causes an increase in numbers of the other. This is due to an increase in availability of resources formerlyExpand
Holocene bioherms (algal ridges and bank-barrier reefs) of the eastern Caribbean
Based on aerial and surface reconnaissance of shallow-water reefs and algal ridges throughout the Lesser Antilles and coring of reef-ridge structures on St. Croix, Martinique, Antigua, andExpand

Photosynthetically enhanced calcification has been studied in the hermatypic coral, Acropora cervicornis, and dark rates of calcification are unaffected by the addition of these compounds. Expand

The commonly observed high diversity of trees in tropical rain forests and corals on tropical reefs is a nonequilibrium state which, if not disturbed further, will progress toward a low-diversityExpand
Light Control of Growth Form in Colonial Reef Corals: Computer Simulation
Computer simulation with plotter output reveals the close interrelation between ambient light and the skeletal morphogenesis of the massive Caribbean reef coral Montastrea annularis. This techniqueExpand
Holocene sea-level change and coral-reef growth at Huon Peninsula, Papua New Guinea
At the tectonically rising terraced coast of Huon Peninsula, Papua New Guinea, a Holocene reef is emerging by as much as 12 m. A clean seacliff section 8 m high provides detailed evidence of theExpand
Geology of Coral Terraces, Huon Peninsula, New Guinea: A Study of Quaternary Tectonic Movements and Sea-Level Changes
A spectacular flight of terraces occurs on the northeast seaboard of Huon Peninsula, New Guinea. The terraces are clearly developed for more than 80 km and rise to over 600 m. They are builtExpand
