Proceedings of the Seventh International Coral Reef Symposium, 1992
The Seventh International Coral Reef Symposium was organized by the University of Guam Marine Laboratory, under the auspices of the Committee on Coral Reefs of the International Association of Biological Oceanographers and the International Society for Reef Studies in Guam, Micronesia, from 22-27 June 1992.

Presentations were divided into 31 mini symposia and showed an increasing number of papers on management and sustainability of coral reef resources, such as: roles of marines reserves in coral reef fisheries, multispecific modelling of coral reefs as a tool for their management, community-based management of coral reefs, public awareness and education, as keys to coral reef conservation, coastal engineering practices to reduce effects of development on coral reefs, biology and economics of giant clams, natural versus anthropogenic disturbances to coral reefs).

Abstract

Paleoclimatic records preserved in the skeleton of massive Porites colonies have previ- ously been retrieved using variations in chemical composition (Schneider & Smith 1982; Shen et.al 1987; Lea et.al 1989; Linn et.al 1990). X-ray dif- fractometry is a method for the recognition of crys- talline substances based upon their crystal structure and inter-atomic distance. In pure chemical sys- tems the patterns are perfectly reproducible. How- ever, in impure, natural systems, small deviations occur. Powder X-Ray Diffraction analysis was used on Porites skeletal material removed from a near- shore and an outer-shelf coral reef. Results suggest a climate-correlated property ex- ists within the banded corals. Corals from outer reefs of the Great Barrier Reef appear to respond sympathetically to parameters associated with the Index of the Southern Oscillation. Corals nearer to shore respond to parameters associated with only one sector of the SOI, Mean Sea Level Pressure measured at Darwin, Australia. Periods of ENS0 activity are manifested in both proxy records as a distinct negative relationship with the relative me- teorological data sets.

Abstract

Studies at Buck Island Reef National Monument (St. Croix) and Virgin Islands National Park (St. John) by scientists in the U.S. National Park Service Coral Reef Assessment Program re- vealed the effects of Humcane Hugo on individual coral species, community parameters, and overall reef structure. Effects of the storm varied with depth, coral species, location relative to the storm path, character of the pre-storm communities, and ecological history. Live coral cover, initially less than 30% at all sites, dropped by 40 to 73%. Cover by the dominant species Montastrea annularis de- clined about 35% on the St. John reefs. At Buck Island, Acropora palmata cover, already reduced from 85% to 5% by white band disease and storms, fell to 0.8% after Hugo. Some areas on the south side of Buck Island were reduced to rubble pave- ment while other areas escaped serious damage. Data from cores at Buck Island reveal the influence of wave energy and storm frequency on overall reef character. Patchiness and variation in the responses of different species, zones, and entire reefs to the storm suggest that assessment of long-term trends in reef structure and composition requires analysis of changes at permanent study sites distributed over large areas.

Abstract

The ASEAN-Australia Living Coastal Resources project has successfully established and run one of the world's largest regional monitoring programs on coral reefs over the last 7 years. The project has been a collaborative effort between scientists of five ASEAN countries (Indonesia, Malaysia, the Philippines, Singapore and Thailand) and scientists from Australia, principally the Australian Institute of Marine Science. The ~poiect resulted from initiatives by ASEAN senior scientists and is run by these ASEAN scientists through a management committee. Australia provides financial support and some technical assistance. The initial emphasis was on basic techniques, identifying the coral reef benthos as recognizable life form cat- egories and examining fish populations, targeting the species of preference for fishermen and tourists. The techniques have been refined through repeated use in the region, and higher level taxonomic resolution is performed in most countries. All data have been assembled in a regional database maintained in Bangkok, such that regional scale comparisons over a 7 year time span can be performed. The Living Coastal Resources project is seen as a model for conducting large scale monitoring programs involving many different countries, at relatively low cost, and with very few problems.

Abstract

Using a synthetised map of biobuilders' vitality, the incoming nutrient-enriched freshwater impact on benthic communities was assessed. A coral community survey was achieved in one rainy season. Reef water salinity and dissolved inorganic nutrient content were analysed during a rainy and a dry season. A high degree of coral mortality (90- 100%) was found on the outer reef flat, where the dead substrate was covered up to 80°h by boring sponges. According to hydrology and biological in- dicators, degradation may be attributed to an ac- cumulation of organic matter, issued presumably from sugar cane refinery waste water. Inner Scler- actinians are submitted to nutrient-enriched (mainly N) submarine groundwater discharge, but coral degradation (turf-coral concurrence) was only found along the inner edge of the reef flat, which further receives P coming from the necrotized area of the reef flat.

Abstract

Hermatypic corals have been shown to incorporate particulate matter in their skeletons. By utilising annual density bands, coral skeletons could be used to determine past sediment levels and detect any recent increases that the organism has experienced, whether from anthropogenic or nat- ural sources. For this to be a viable method the process by which sediment becomes incorporated must be established. A method has been developed for embedding relatively large sub-samples from Porites colonies, which contain both coral skeleton and the associated tissues. This method is designed to reduce the possible loss of particles from the sam- ples and limit contamination. A phototransect tech- nique was used to assess the number and positions of incorporated particles. This requires initial sur- face staining of the samples for light microscope photography, followed by scanning electron micro- probe analysis to determine the nature of the par- ticles. Results suggest that sediments from an iso- lated stressing event (exposure to titanium dioxide powder for 24 hrs) can be held within the tissues for at least three months. Scarring of the corallum, similar to that produced by parrotfish, results in incorporation of sediments into the skeleton.

Abstract

Coral communities under tabulate corals have been shown to have lower coral abundance, reduced diversity and different species composition relative to unshaded communities. It has been pos- tulated that these patterns result from light atten- uation which causes high mortality of understorey coral fauna. In the present study, settlement plates were placed in the open and under living colonies of both arborescent and tabulate Acropora species. Recruitment of juvenile corals onto the settlement plates was 56 to 73 times greater for the unshaded plates, relative to those in the understorey. This is evidence that the successful establishment of cer- tain colony types may inhibit the settlement of po- tential competitors. Because recruitment rates were similar for both tabulate corals and the more open arborescent colonies, it is unlikely that reduced light levels were the major cause ofthe lower recruitment rates of the understorey corals. There was a differ- ence in the relative abundance of the major taxa of recruits between the understorey and open settle- ment plates. The results suggest that settlement preferences as well as post-settlement processes probably structure the understorey communities due to indirect competition from the overtopping species.

Abstract

The occurrence of anthocaulus-like ju- veniles of Fungia scutaria on encrusted dead coralla (=parent coralla) of the same species was exam- ined. These parent coralla bore an average of about 23 juveniles per corallum. The juveniles were more abundant on the aboral surface than the oral surface and nearer the edges than the centers of the parent coralla. Juveniles occurring on the same parent cor- allum were usually phenotypically identical to each other suggesting that they were asexual clone mates rather than recruits from sexually-derived planula. These juveniles may therefore be derived from re- sidual tissues left behind in the parent corallum after its death. The longevity of mesentarial fila- ments excised from mature corals suggested that these residual tissues may survive long periods of time before differentiating into juvenile corals. The development ofjuveniles from residual tissues may depend on the removal of the inhibitory influence of the original parental mouth. Asexual prolifera- tion of Fungia scutaria from dying parent coralla may be important in maintaining their populations on shallow reef flats in Kaneohe Bay, Oahu.

Abstract

During 1988-1 990, assessment of coral reef communities by the transect method intro- duced by the ASEAN-Australia Cooperative Pro- gram on Marine Science was made in Thai waters, Andaman Sea. However, the method was modified to siut the conditions of coral reefs in the Andaman Sea. The reefs are found in different environments ranging from near-shore to near the continental shelf edge. From a total of 55 transects on 36 reefs, the average percentage cover (+SD) of live and dead corals are 39.4% ( -t 19.7%) and 55.4% ( _+ 20.6Yo) respectively. Using an arbitrary category, 11 reef sites are healthy (Oh cover of live to dead coral >2:1), 25 sites are unhealthy (% cover of live to dead coral > 1:2) and 19 sites are fair (Oh cover of live to dead coral in between 2: 1 and 1:2). A total of 82 positively identified species from 49 genera of scleractinia were recorded from the transects. The most abundant species with highest cover are Porites lutea, Acropora nobilis, A. formosa and P.(Synaraea ) rus. Coral communities on the off- shore islands are usually formed of distinct ho- mogeneous species on slope zones, while those on near-shore islands are comprised of mixed species. The sample of long term monitoring during 1988- 1992 of the reefs on the west coast of Phuket Island show the decrease and increase percent cover of corals due to humanlnatural impacts and manage- ment in the area.

Abstract

Three species of scleractinian coral, Montipora digitata M aequituberculata and M. pel- tijorrnis, spawned twice a year at Magnetic Island, Queensland. Spawning occurred during autumn and spring after the full moons in March and Oc- tober respectively. Monthly gametogenic 'samples collected for two morphs of M. digitata showed that fecundity differed between the two morphs, and that spawning was less intense in March than in October. Fewer colonies spawned in March and those which did released fewer gametes. All colonies that spawned in March also did so in October. Sam- ples from previous years suggest that the intensity of the March spawning may vary considerably from year to year.
