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… 
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.
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 decrease
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 a

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).


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, Atlantic

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 formerly

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.

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-diversity

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 technique
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 the
