Phoenix From the Ashes? Repetitive Mass Mortality and the Biogeology of Southern Arabian Gulf (United Arab Emirates) Coral Systems.
Bernhard Riegl
Biogeological dynamics consist of a combination of community-ecological responses based on individual-species physiological tolerance limits to a dominant environmental stressor and their consequences on carbonate sedimentological properties. This interplay was investigated in coral carpet systems (biostromal coral frameworks) in the southern Arabian Gulf in Abu Dhabi and Dubai (UAE). Five coral assemblages occur in the area: (A) low coral cover, widely spaced Porites lutea (B) high coral cover (biostromal framework), dense Acropora spp. C) low coral cover, widely spaced faviids (D) low coral cover, individual Siderastrea savignyana only (E) high coral cover (biostromal framework), dense Porites harrisoni. Coral community dynamics and the potential for the accretion of reefal limestones was found to be controlled by recurring sea-surface temperature anomalies. The effects of these heating or cooling events are mass mortality of all Acropora species. COADS data and time-series of AVHRR satellite data suggest potential recurrence periods of 11-17 years. Extreme positive SST anomalies only appeared after 1986. These events result in large areas of dead framework with only interspersed live corals (the non-Acropora members in the assemblages). Dead frameworks are intensely biocorroded and break down rapidly. Thus the next generation of framebuilders has to settle on the same substratum as the previous generation and no reef-structure, which would require several generations of corals growing on top of each other, is built. However, since only limited space is available for coral settlement (most of the seabed being sandy), these recurrent mass mortalities of a dominant space-competitor allow competitively weak species to persist in the system and thus maintain diversity. Strong recruitment pulses from surviving pockets of Acropora ensure the survival of this community-component in time.

Fifty Years of Impacts on Coral Reefs in Bermuda
C. B. Cook, Richard Dodge, and S. R. Smith
[Chapter Abstract]
The high latitude coral reefs of Bermuda have been impacted by two major kinds of events since the early 1940s. The first was the dredging operation in Castle Harbour which led to the construction of Kindley airfield (now the Bermuda Air Terminal.) The associated sedimentation, turbidity and altered hydrology caused a mass mortality of corals, especially of the major reef-building genus Diploria. While there has been post-dredging recruitment of corals, D. strigosa, a species sensitive to sedimentation, has been particularly slow to recover and is less prevalent at this site than elsewhere in Bermuda. Ship groundings comprise the second class of event: since 1940, thirteen major ship groundings have occurred on the reefs which have destroyed an estimated 1% of the outer reefs. Studies of the recovery and recruitment of corals at a major grounding site indicate that these processes occur very slowly in Bermuda. It is estimated that 100-150 years would be required to restore coral coverage and species diversity, with species of Diploria being particularly slow to recover. Recent episodes of coral bleaching in Bermuda are considered to have had very little effect on coral populations and reefs.

Long-Term Monitoring (2.5 Years) of Effects of Short-Term Field Exposure of Stony Corals to Dispersed and Undispersed Crude Oil
Richard Dodge and Anthony H. Knap
[Chapter Abstract]
A field experiment was conducted to evaluate long-term effects to shallow sub-tidal coral reef species from short-term exposure to dispersed and untreated crude oil. The study location was in the northwestern Laguna de Chiriqui, Caribbean coast of Panama. Experimental sites consisted of 900m2 plots which were enclosed by a boom with .45cm deep skirts. All sites contained shallow subtidal coral reefs. One site was designated as a control. One site received dispersed oil at a target concentration of 50ppm for 24 hours, representing a high exposure. One site received only crude oil at an amount of about 1 l/m2 for a duration of approximately 48 hours, representing moderate exposure.
Prespill chemical and biological parameters were collected in March and mid November, 1984. The experimental spill was conducted in late November, 1984. Monitoring of parameters continued periodically until August, 1986. Biological parameters that were measured included epifaunal and epifloral coverage of the coral reef substrate utilizing plotless line transects. Skeletal growth of four selected coral species was also measured at each site. Chemical sampling involved analysis (not reported here) of large and small-volume water samples for GC and GC/MS together with large-volume water samples by pumping through XAD resin.
Results indicated that the coverage of all organisms, hard corals, all animals, and all plants was significantly depressed in the Dispersed Oil treatment compared to the Control station. Little recovery of most organisms was evident some 20 months after initial treatment. Coverage parameters of the Oil Only treatment were generally lower than, but not usually significantly different from coverage of the Control. Of the four coral species investigated for growth, two (Agaricia tennuifolia and Porites porites) showed significant effects from exposure to dispersed oil (reduced blade and tip extension rate at the dispersed oil site). These results provided useful indications of long-term effects from short-term field exposure of corals and coral reefs to oil and dispersed oil. Information from this and other field and laboratory studies benefits marine management by providing data upon which to base informed decisions regarding dispersant use in tropical areas.

Oil Refinery Impacts on Coral Reef Communities in Aruba, N.A.
C. Mark Eakin, Joshua S. Feingold, and Peter Glynn
[Chapter Abstract]
From 1925 to 1985, Lago Oil and Transport Co. operated a transshipping terminal and refinery on the southeastern coast of Aruba, N.A. This facility has affected the nearshore marine ecosystem through both oil contamination at the harbor and tanker berths, and from disturbance related to shipping, dredging and construction. The impact of this facility on nearby coral reef communities was studied from January 1987 to August 1989. This included an analysis of reef community structure comparing sites adjacent to the refinery with those upstream and downstream, the modern and historical growth of the predominant coral species, and recruitment of new corals. Both upstream and downstream control sites were in good health and exhibited high diversity. In contrast, reefs adjacent to the refinery exhibited low density and diversity of live corals and abundant dead coral rubble. Additionally, periods of construction in the inner harbor and on surrounding spoil islands and high refinery activity corresponded well with periods of reduced coral growth near the refinery. Although the relative importance of oil contamination, sedimentation and other anthropogenic effects is uncertain, our observations suggest that sedimentation and other physical stress resulted in substantial reductions in environmental quality at the disturbed sites. Coral recruitment at the highly impacted sites showed hope for recovery if these environments are protected from renewed perturbation.

Feeding-Entrained Circadian Rhythms in Fishes
Richard E. Spieler
There has been sufficient work done in fishes to warrant a review of feeding-entrained rhythmicity, if only for comparative reasons. Relative to the extensive work with laboratory mammals, however, information on this topic in fishes is meager. An attempt at a broad overview at this point is fated from the outset to be data poor and speculation rich; hopefully this paper will, nevertheless, serve a heuristic role. Specifically, the paper addresses five questions regarding feeding entrainment of circadian rhythms in fishes: Does feeding entrain rhythms in fishes? How? Why? So what? and What next?
