This coral community was discovered in March 2012 by one of the co-authors (M. Fukuda) and is believed to be one of the largest communities of A. hyacinthus off the coast of Kyushu. In southern Miyazaki, reef-building corals had been found in abundance before the outbreak of the coral-eating snails Drupella fragum in 1987, which drastically diminished the coral population in this region (Takayama and Shirasaki 1990; Uchida 1994).

Consequently, there are decades of spawning observations, which we present and explore here with the aim of making it easier to predict when species spawn at Sesoko Station. The data include over 700 spawning observations from 87 species of reef-building hermatypic corals. Almost all spawning occurred between dusk and dawn, with most spawning activity concentrated in the 2 to 4 hours after sunset. Some phylogenetic patterns were evident: most Acropora species spawn on or around the 6 full moon after December 21 (the northern hemisphere winter solstice); spawning in common species of merulinids and Porites appears to be concentrated around the 7 full moon and spawning in the fungiids around the 8 and subsequent full moons. The night of peak spawning with respect to the night of the full moon varied considerably among years in common Acropora species, but was dependent on the calendar date of the full moon in May or June.

Ontogenetic changes in the distribution pattern of green fluorescence in coral are not fully understood. We investigated changes in the intensity and distribution pattern of green fluorescence of the corals Acropora tenuis, Pocillopora damicornis, and Isopora palifera during early developmental stages. Green fluorescence distribution in larvae differed among the three species studied and changed after the larvae metamorphosed into primary polyps. Green fluorescence distributed mainly in the epidermis of P. damicornis and I. palifera larvae but in the gastrodermis in A. tenuis larvae. In P. damicornis and A. tenuis primary polyps, green fluorescence was present around the oral opening and in a ring structure below the tentacular ring. Green fluorescence was also present on the tips of the tentacles of P. damicornis and I. palifera primary polyps. Furthermore, green fluorescence intensity in A. tenuis primary polyps increased significantly after inoculation of symbionts, irrespective of the success of symbiont acquisition. In I. palifera, the fluorescence in­ tensity decreased and, in some cases, disappeared after the acquisition of symbionts. Moreover, bleaching stress increased green fluorescence in P. damicornis juveniles. The present observations suggest that green fluorescence intensity in juvenile corals is influenced by the presence or acquisition of symbiont cells as well as by stressful conditions. This study also suggests that GFP might have different functions among coral species and at different developmental stages of the corals.","PeriodicalId":118057,"journal":{"name":"Galaxea, Journal of Coral Reef Studies","volume":"142 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123420877","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ele­mental analyses were performed from the surface to the interior of the coral specimen along its growth axis at 1­mm intervals, generating the near­monthly resolved time series for the Mg/Ca and Sr/Ca ratios. The ratios demonstrate clear annual cycles, which are assumed to reflect variations in the sea surface temperature (SST). Comparing with the annual maximum and minimum values of SST, the following Mg/Ca -SST and Sr/Ca-SST relations were determined: Mg/Ca (mmol/mol)＝−1.72＋0.193×SST and Sr/Ca (mmol/mol)＝11.83−0.098× SST. These relations are different than those of previously published studies. The reason for this difference is unclear; however, it may be related to vital effects that have been observed for geochemical proxies in coral skeletons and to differences in chemical composition of seawater and in sampling procedure.","PeriodicalId":118057,"journal":{"name":"Galaxea, Journal of Coral Reef Studies","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124530972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
