TL;DR
Abnormal processes of calcification, such as regenerating lesions and neoplasia, situated near the tips of colonies of Acropora palmata (Lamarck) suppressed normal linear growth, indicating a functional minimal area in terms of energy supply.
Abstract
Abnormal processes of calcification, such as regenerating lesions and neoplasia, situated near the tips(<25 cm) of colonies of Acropora palmata (Lamarck) suppressed normal linear growth. Branches having neoplasia at a larger distance from the tip do not grow significantly differently from controls. This indicates a functional minimal area in terms of energy supply. Neoplasia are pure aragonite and have the same coenosteal structure as regenerative skeletal material. Regeneration of tissue as well as tissue+skeleton lesions involves the simultaneous formation of tissue and regenerative skeleton, trapping foreign material under the regenerated surface. Recovery of a damaged surface slows down with time and this may, in other coral species, result in permanent lesions. A. palmata recovered from all lesions (n=32) within 80 d and appears to be a superior regenerator among Caribbean corals. This is consistent with other life-history characteristics of this highly specialized coral species.

It is concluded that a number of the most successful corals are adapted to fragment, and have incorporated fragmentation into their life histories.

Results suggest that a decrease in the natural water temperature of Hawaiian reefs would be more harmful to corals than a temperature increase of the same magnitude.

The calcification rate of reef corals grown in darkness for prolonged periods of time to remove the zooxanthellae is considerably reduced and seems independent of the light intensity.

The distribution and abundance of juvenile corals were examined at depths from 3 to 37 m on the reefs of Curaçao and Bonaire (Netherlands Antilles) and shows that these species employ very different life history strategies.

It is suggested that long-term reef calcification and growth rates are highest on reefs periodically distrubed by storms of intermediate intensity, which may explain the rapid recovery of reefs from all but the severest hurricanes.

This chapter discusses coral skeletogenesis, focusing on the morphology of the skeletogenic tissues of the coral Pocillopora damicornis, and reviews the light and electron microscope studies carried out in this regard.

Under water light values at a depth of 12–13 m were reduced from about 30% to less than 1% surface illumination and calcification rates in Madracis mirabilis and Agaricia agaricites were observed to decrease by 33%.

Using 45Ca incorporation into the coral skeleton as a measure of calcification rate, the effect of temperature on clacification rate was studied in the hermatypic coral Pocillopora damicornis, showing both 27° and 31°C temperature optima, one or the other being dominant depending on the natural water temperature to which the coral was adapted.

It is suggested that the algal mat caused the corals to expend energy to keep their surfaces clean, so that death followed the exhaustion of metabolic reserves during periods of minimum nutrient availability, and that the paucity of small Acropora palifera colonies in an otherwise favourable habitat.

The frequent oil spills, together with the phosphate dust that reaches the sea, seem to be the factors that cause eutrophication in the shallow lagoon waters of the coral region, and thus the development of algae on the coast of corals is stimulated.

The rate of skeletal regeneration in a population of the branched coral Stylophora pistillata (Esper) is surprisingly fast, and during the first 2 months of regeneration, damaged colonies grew twice as fast as intact control colonies.

The skeleton of the three species tested here is strongest when stress is applied parallel to the growth direction of the polyps, and the adaptive value of porosity modification may explain differences in porosity and strength between highly stressed branched growth forms and more moderately stressed massive growth forms.

This report draws an example from a spontaneous tumor occurring in the scleractinian coral, Acropora formosa (Dana), and relates it to the growth patterns observed in this coral and other coelenterates.

37 Citations1975Conrad D. Clausen, Ariel A. Roth
In two coral species, Porites compressa and Pocillopora damicornis, 45Ca incorporation rates were obtained from short laboratory incubations using apical portions of freshly collected coral branches, and these rates are considerably higher than those previously obtained in the laboratory, and compare favorably with field growth rates.
PaleobiologyThere was biological disturbance on Pleistocene coral reefs
27 Citations1981Les Kaufman
Chimneys found on coral fragments excavated from the Jamaican Falmouth Formation indicate that algal gardening, and thus biological disturbance, has been an integral aspect of Caribbean coral reefs since at least the last sea-level stand, some 125,000 yr BP.
