Seasonal changes in species composition and size frequency distributions of six sympatric coexisting species of Trapezia associated with the hermatypic coral Pociliopora damicornis were investigated to analyze their population structure, mechanisms promoting coexistence, and the organizing processes of the symbiont community. All Trapezia species showed a long recruitment season, but they could be divided into two groups according to variations in their size frequency distribution pattern throughout the year: Young T. ferruginea and T. guttata occurred all year round, while young T. cymodoce, T. areolata, T. digitalis, and T. sp. were absent part of the time (a few months). Recruitment of T. cymodoce and T. areolata occurred from April to August and from February to March, respectively. Young T. digitalis were abundant only in July. Even among larger colonies, those harboring only one or two Trapezia species were rather common. This suggests that agonistic interactions occur among these crab species. Although it is also true that host colonies harboring several species are sometimes found. Since no conspicuous hierarchy in inter-specific agonistic interactions has been demonstrated (Tsuchiya and Yonaha, 1992), new crab recruits of any species can invade colonies lacking strong competitors.Although these crab species require very similar resources, i. e. pocilloporid corals as their habitat and mucus produced by host corals as food, their coexistence on larger single colonies is promoted by several mechanisms: 1) different recruitment seasons, 2) weak hierarchy of agonistic interactions among the six species, and 3) microhabitat segregation between adults and young on a colony.

In the summer of 1998, mass coral bleaching occurred in many reefs around the Ryukyu Islands. Various sized colonies of completely bleached Pocillopora damicornis were collected in order to study the effect of the coral bleaching on the structure of its associated community. Although six species of Trapezia were collected in this survey, and it was comparable to its species richness on healthy Pocillopora, bleached colonies harbored fewer individuals and species of obligate symbionts than unbleached colonies, before the bleaching event. Even on the larger colonies, of which the volume of interbranch space was > 222cm3, no obligate symbionts were found. Heterosexual pairs of the symbionts such as Trapezia spp., Alpheus lottini and Paragobiodon spp. were rather uncommon and the abundance of ovigerous females of Trapezia was lower and their clutch size was smaller than usual. It was quite unusual that large numbers of the symbiont crab Cymo melanodactylus were found on completely bleached colonies of P. verrucosa and Acropora aspera.

Coral bleaching occurred at various places around the Ryukyu Islands in summer 1998. Several researchers have suggested links to high sea surface temperature. However, the observation of coral bleaching around Ishigaki-jima of the Yaeyama Island Group where the bleaching has been extensive since July shows that there was already a sign of the event during the Baiu rainy season.The study of corals on Ishigaki-jima presents the following:1) Coral bleaching was probably caused by the continued high sea surface temperature from July through September 1998.2) The corals had already been severely damaged by the sedimentation of red soil from the disturbed land surface during the Baiu season of the year which had nearly twice as much rainfall as normal year. The subsequent high sea surface temperature in summer contributed to accelerated bleaching.The observation of bleaching in moats around Ishigaki-jima in summer 1998 suggests that the progress of bleaching be divided into the following three time stages:1) Early stage: from around June 20 through early August2) Mature stage: from middle August through early September3) Final stage: from middle September through middle OctoberThe bleaching process divided by these stages is synchronous, with a time lag, with the seasonal change in sea surface temperature and the prevailing weather conditions in Okinawa.

The bleaching of hermatypic corals that occurred in the summer of 1998 throughout the Nansei Islands, southwestern Japan, was the most extensive one in recent years. Field investigations using a large quadrat (10×10m) method distinguished this bleaching from prior episodes as (1) the largest in scale, (2) the most severe, and (3) causing the highest mortality. At two shallow reef flat sites, a total of 85.9 and 92.2% in coverage of hermatypic corals were bleached and mortality reached 60.7 and 78.7% in the most thermally susceptible acroporids. Bleaching damage varied among species and habitats. Dominant coral species were classified into four categories of bleaching; I. both rates of bleaching and mortality were high (e. g. Acropora hyacinthus, A. pulchra), II. rate of bleaching was high, but mortality was low (e. g. A. digitifera, Montipora digitata), III. both rates of bleaching and mortality were low (e. g. Platygyra ryuhyuensis, Porites cylindrica), IV. mortality (due to bleaching) was higher than rate of bleaching (Leptoseris gardineri). Acroporids in Category I were thermally more susceptible than those in Category II as the surface area per volume of skeleton was larger. Species categorized into Category II and III were considered to be best adapted to severe thermal environments such as the shallow reef flat and moat. The mass bleaching during the summer to autumn of 1998 was considered to be caused mainly by extraordinary high thermal stress. Meteorological data showed that average sea water temperatures have risen by 0.7°C in summer and 2.0°C in winter over the past 85 years, resulting in more frequent and serious disturbance by bleaching on coral reefs in recent years.

Coral bleaching was described in Kikai-jima (Kikai Island) in October, 1998. Mortality of coral species belonging to the families Acroporidae and Pocilloporidae was the highest of all scleractinian corals in this island. In contrast, some species of the genera Psammocora and Pavona were never or seldom damaged. These results were similar to those observed in the other Indo-Pacific regions. Significant differences in mortality among families could be attributed to the their geological ranges. The species that were free from appreciable damages by bleaching belong to the families which first appeared in the geological periods when the climate was globally warm (greenhouse periods).

Coral bleaching is whitening of corals due to loss of zooxanthellae and/or their pigments caused by various environmental stressors (see review Brown 1997, and references therein). In Okinawan coral reefs, Yamazato (1981) reported that the extent of bleaching was different in different species, and suspected that the cause of the coral bleaching was elevated sea water temperature. In the summer of 1998, intense and extensive coral and coral reef bleaching events occurred in various regions in the Ryukyu Islands. The event was more severe than that in 1980 (Yamazato, 1981). It seems that the proximal cause of the 1998 bleaching was also unusual high sea water temperature observed over the wide area. When we visited Kudaka Island (26° 09' N, 127° 53' E) in late July 1998, corals were not bleached in the shallow moat (about 2 m maximum depth at low tide). On October 25, 1998, however, many of coral colonies were already bleached. The coral bleaching was suspected to have started in late August to September as was observed in other localities (Nishihira pers obs, see also Nishihira 1999). Since we found distinct bleaching patterns in some colonies of massive Porites in October 1998, we thereafter photographed them repeatedly to monitor recovery process until March 1999. Although the proximal cause of the bleaching was suspected to be elevated sea water temperature, data records were not available for Kudaka Island.

Time course of enhancement of calcification of the coral Galaxea fascicularis in light and decay of light-enhanced calcification in darkness were studied. The hourly rates of calcification and of photosynthesis/respiration of isolated polyps of G. fascicularis were measured successively in light or in darkness using the alkalinity anomaly technique. Corals were kept in darkness for 15-19h before experiments. Calcification rate during 50min incubations in light was about four times higher than that during previous incubation in darkness. Light-enhanced calcification did not decrease abruptly when the coral was returned to darkness but decayed gradually to about 46%, 3h after illumination was terminated. The rate of light-enhanced calcification increased gradually when corals were incubated in light. The photosynthetic uptake of CO2 by corals held in light was 3.7 times faster than CO2 uptake due to calcification. Dark respiration increased after 50min incubation in light. The slow decay of light-enhanced calcification in darkness suggests that there is an internal pool of substances which enhance calcification, and that accumulation of the substances might sustain high rates of calcification in darkness.

Extensive bleaching of corals occurred around Akajima, Okinawa, in the summer of 1998. Bleaching was observed in a few corals in late July 1998, but by the end of August many pocilloporiid and acroporiid corals were bleached. The bleaching frequency, relative to total coverage of corals, at 15 sites (1.3-7.2m in depth) around Akajima ranged from 55.9 to 97.4% in late September 1998. We measured 2m x 2m quadrats at each site. Three out of 4 sites that showed over 90% bleaching were located in either a moat or inside of a bay, where water exchange was slow. One site was characterized by a dominant occurrence of branched corals of the genus Acropora. This group was more easily bleached than other morphologic groups around Akajima. Sea surface temperature over 30°C (normally about 28°C) was recorded for a month in August. This high temperature may have been a primary factor of the coral bleaching. Coral diseases caused by viruses or bacterial infection after bleaching were not observed. Geographical features, rate of water exchange, and composition of coral species seem to be responsible for the differences in extent of bleaching.

In 2012, Dr. Ann F. Budd and colleagues revised the taxonomy of the families Mussidae and Faviidae, based on the published molecular phylogenetic data and the detailed skeletal morphological analyses. In this revision, Atlantic Mussidae and Faviidae were treated as the separate families from the Indo-Pacific ones. Ac-cording to this revision, Indo-Pacific Mussidae and Faviidae, and also the genera Favia and Montastraea were revised taxonomically and these names were changed. These changes may confuse some coral scientists on various situations such as writing papers. Therefore, in this paper, I summarized the revision of the families Mussidae and Faviidae, explaining the reason why they were revised.
