Adult A. planci when inverted had a normal righting response time (in seconds) of 163±1 (mean±SE; N=298). Injection of concentrated salt solutions led to negative effects on adult A. planci. The spines bent down, body collapsed and the starfish became comatose and died after 24-hours. The higher the salt concentration, the higher is the % comatose indivi- duals. In addition, comatose specimens failed to recover with time. Mortality was highest at the highest treatment concentration with LC90 of 285.3 and LC99 of 383.2 ppt. The effects of time, salt concentration and its interaction (salt concentration x time) were significant ( p=0.00). The ionic and osmotic disruption of the coelomic fluid can seriously affect physiological functions of the organism including neuromuscular activity. Thus, in the control of A. planci, concentrated salt solution can be used as a cheaper alternative to dry acid, acetic acid or ammonium hydroxide, all of which are expensive, may not be locally available and not environment friendly.","PeriodicalId":118057,"journal":{"name":"Galaxea, Journal of Coral Reef Studies","volume":"17 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":"129800444","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 purpose of this study is to investigate the diversity, species composition, and community structure of Acropora in the Gulf of Thailand. A 30×1 m belt transect with 3 replicates were employed in each of 80 stations at 30 islands along the Gulf of Thailand. The overall diversity indices at all stations were between 0.52.0 while the evenness indices between 0.5-1.0. Commu nity structure of Acropora, based on coverage area, varied significantly between habitats depending on location. Based on the surveys, community structure could be di vided into 4 groups. The first group was the station at Klang Island on the winwardreef slope (kl12) and the station at Kra Island on the winwardreef slope (kr12), having A. aculeus as a dominant species and at station Kra Island on the leewardreef slope (kr22), having A. nana as a dominant species. The second group was the station at Klang Island on the leewardreef slope (kl22), which had A. formosa as the dominant species. The third group was the station at Kra Island on the leeward-reef flat (kr21), which had A. cf. copiosa, A. longicyathus, A. tenuis and A. microphthalma as the dominant species. The last group of the stations had common species and rare species of Acropora. This study showed that the current condition of Acropora in the Gulf of Thailand showed recovery after the bleaching phenomenon in 1998.","PeriodicalId":118057,"journal":{"name":"Galaxea, Journal of Coral Reef Studies","volume":"89 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":"121482181","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}

There are no reports, however, concerning the taxonomic composition of cold-water corals and other benthic megafauna in the southern Emperor Seamounts area of the North Pacific Ocean. We analyzed benthic samples collected from a research vessel during scientific surveys and by scientific observers onboard commercial fishing vessels to examine the faunal composition of cold-water corals and other megabenthos in the southern Emperor Seamounts area. Seventy-eight genera of cold-water corals were identified. Gorgonians (Alcyonacea with solid axis) occurred at high frequencies with wide vertical distribution ranges, and appeared to be the major components of habitat-forming cold-water corals in the area. Scleractinia occurred at frequencies similar to those of gorgonians, but over limited depth ranges. Among other benthic megafauna, Crustacea and Echinodermata occurred at high frequencies. The results demonstrates that the regional characteristics of deep-sea benthic megafauna in the southern Emperor Seamounts area is more similar to that near the Hawaiian Islands than those reported from Aleutian, other Alaskan, Californian and Japanese waters.","PeriodicalId":118057,"journal":{"name":"Galaxea, Journal of Coral Reef Studies","volume":"10 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":"127636440","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}

Green (Gs) and brown (B) morphs of the coral Galaxea fascicularis have different contents of green fluorescent protein (GFP). To understand the function of GFP in the stress responses of the coral, we exposed polyps isolated from B and Gs morph colonies to medium or strong light (200 and 1000 μmol quanta ms) at 26 or 32°C for 6 h. Polyps were then allowed to recover for 6 h under dim light. Although the GFP content was markedly different between Gs and B morphs, in hospite zooxanthellae in polyps of both morphs showed similar decreases in photochemical efficiency (Fv /Fm) after strong light treat ment at normal or high temperature. Isolated zooxanthellae of both morphs showed similar decrease in the photo chemical efficiency under light stress, indicating that they had similar tolerance to light stress. The present results suggest that fluorescent protein does not increase the tolerance of polyps to strong light and high temperature stress in G. fascicularis and that further studies are nec essary to elucidate the function of GFP in this coral.","PeriodicalId":118057,"journal":{"name":"Galaxea, Journal of Coral Reef Studies","volume":"19 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":"127987083","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}
