The degradation of organic carbon in this seawater was monitored for more than three months in dark, unstirred polycarbonate vessels by measuring the concentration of organic carbon in the seawater. The concentration of organic carbon gradually decreased to the background level of the refractory organic matter. The ratio of labile organic carbon to total organic carbon was about 30% in the water within the reef, and 10% in the water outside. The concentration of inorganic nutrients gradually increased with the degradation of the organic matter. In terms of the cell density and cell biomass of bacteria, the doubling rate was initially about twice a day and then declined during the incubation. Rate of degradation of labile organic carbon was about 20mmol C/m2/day in the reef. It was much smaller than the respiration rate reported for the whole coral reef community. This indicates that benthos like corals plays a major role in carbon dynamics in the coral reef. The result that the refractory organic concentration in the reef is lower than that in the outer sea indicates that the coral reef has the role of carbon sink in that organic carbon might be absorbed to the sedimentation particle.","PeriodicalId":432348,"journal":{"name":"Journal of The Japanese Coral Reef Society","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114628810","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}

These three species has thus far been reported only from Japan (Veron 1998 Veron and Fenner 2000 Fenner 2001 Fenner 2002) except for G. deformis in the Red Sea (Veron 2000) and a visual record of it from the Philippines (Veron and Fenner 2000), and H. bonsai in Raja Ampat Islands, Papua Province, Indonesia (Veron 2002). In this paper, we describe specimens of these three species collected from western Luzon and along the Kuroshio current on the eastern coast of the Philippines (Fig. 1) thereby extending their ranges farther south and west. This also increases the number of species reported from the Philippines to 464 from the 462 species reported by Veron and Fenner (2000). The Philippines now has 18 species of Goniopora, six species of Hydnophora and nine species of Goniastrea as compared to other nearby countries (e.g. Togean and Banggai Islands, Indonesia with four species of Goniopora, five species of Hydnophora, and four Goniastrea species; Raja Ampat Islands, Papua Province, Indonesia with 17 species of Goniopora, six species of Hydnophora and seven Goniastrea species Milne Bay Province, Papua New Guinea with 11 species of Goniopora, five species of Hydnophora and seven Goniastrea species). Ninety-three percent of the Japanese coral fauna (as inferred from Veron 1992) is shared with the Philippines (based on Veron and Fenner 2000) further emphasizing the likely role of the Kuroshio current in Japanese coral diversity.

Coral reef and mangrove eco-system supporting the resources is also in the threat. The fisheries resources, in essence, need proper management because the resources are renewable and considered common property. Typical conditions for tropic fisheries management are many species, many remote islands, few researchers, many subsistence fisheries, and a strong sense of community. Under these conditions the management regimes that have evolved in Western developed countries have seldom worked properly. Instead, considering efficient compliance and enforcement, the resources should be managed through partnership between the government and the communities (co-management). The resources may be managed more efficiently by a retrospective approach than a pre-emptive approach. Among management tools (e. g. seasonal closure, size limit, gear restriction, catch quota, license, etc.), Marine Protected Area (MPA) seems most effective. In Samoa and Okinawa, co-management of nearshore resources has been implemented with fisheries extension programs in analogous ways. Both cases have seemed successful to date. In the past, the Philippines was infamous for destructive fisheries, but now many successful cases of co-management have appeared with the help of NGOs and international research organizations.","PeriodicalId":432348,"journal":{"name":"Journal of The Japanese Coral Reef Society","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128379191","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}

I have interviewed five informants of the Beja around 'Agetai village on Sudanese Red Sea coast. They gave me forty-five place names, and explained or interpreted those names.They named “intestines of dogs” for the long and narrow part of the particular island and the attached coral reef flat where local people can cross by riding on camels carefully. On the other hand, they named “horns of gazelles” for the high trees of mangroves along the shoreline of the island which were left over by cutting down its branches and foliage for camel forage. They compare coral reef and mangrove landscapes to body parts of dogs and gazelles that they either take care of or hunt. Therefore, Is can characterize that they replace the physical and biological environments at macro-level in the sea (coral reef and mangrove landscapes) for biological environments at micro-level on the land (particular body parts of domesticated animals and wild animals). However, they do not have any general names (classified categories) for topographical features of coral reef.","PeriodicalId":432348,"journal":{"name":"Journal of The Japanese Coral Reef Society","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115365178","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}

Isolated polyps of the coral Galaxea fascicularis were exposed to three temperatures (24, 28 and 30°C) for 7 days and were then allowed to recover for 15 days at 24°C. Both zooxanthellae density and the maximum photosynthetic quantum yield of in hospite zooxanthellae, measured by pulse-amplitude-modulation (PAM) fluorometry, decreased after 7-day exposure to 28 and 30°C. In corals exposed to 28°C, both parameters returned to the initial level after 15-day recovery, but those exposed to 30°C died during the recovery period. A high release of healthy-looking zooxanthellae was evident in the coral exposed to 30°C, while those exposed to 24 or 28°C mainly released degraded zooxanthellae particles. The mitotic index of both retained and expelled zooxanthellae was highest at 30°C. The coral host appeared to lose the capacity of controlling algal cell division and of preferential expulsion of degraded algal cells after 7-day exposure to 30°C. The growth rate of corals was lowest at 30°C. The reduced growth rate, the low release of degraded zooxanthellae particles and high release of healthy-looking zooxanthellae, and increased mitotic index of zooxanthellae, in corals exposed to 30°C for 7 days, suggest that high temperature caused a physiological dysfunctioning at the level of host and that this change may be at least partly responsible for bleaching and the disruption of symbiosis.","PeriodicalId":432348,"journal":{"name":"Journal of The Japanese Coral Reef Society","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115204591","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}

As a result of bleaching, corals drastically decreased in number and coverage at all study sites and final coral coverage, at the heavily destroyed outer reef flat, was only 8.2 % of that prior to bleaching. Differential susceptibilities and survival were noted among coral species and among study sites. Bleaching damage most severely affected the outer reef flat, followed by the reef slope, whereas it less severely affected the inner reef flat, where sea water temperatures were highest. The degree of bleaching response among sites was not simply thermal-dependent but species-related. Several species of Acropora (A. digitifera, A. nobilis, A. formosa, A. pulchra, A. microphthalma, A. hyacinthus, A. echinata, A. subglabra, and so on) suffered the most damage from bleaching, and consequently the rich coral communities disappeared from the outer reef flat and the reef slope. At the inner reef flat, some species of Montipora (M digitata, M cactus, M stellata, M aequituberculata) recovered considerably after bleaching, despite conspicuous bleaching during the early bleaching phase. The present results indicate the possibility that some species inhabiting under thermally severe conditions have potentially acclimatized enough to endure such stress, and consequently they could live for a long period of more than six months in a bleached condition. Although the species richness (number of species) decreased at all sites, the species diversity indices often increased as a few dominant species of Acropora were reduced, and as a consequence, species evenness increased.","PeriodicalId":432348,"journal":{"name":"Journal of The Japanese Coral Reef Society","volume":"310 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132033254","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}
