Diverse microbes are associated with corals, including zooxanthellae, protists, prokaryotes, and viruses. This study aimed to investigate the genetic diversity of the culturable fungi associated with scleractinian corals in the Gulf of Thailand. Ribosomal DNA sequence analysis and morphological analysis of 130 fungal isolates revealed a high diversity of fungal phylotypes from three coral species: Pavona decussata, Pocillopora damicornis and Porites lutea. Ascomycota was the most abundant fungal phylum. The predominant orders included Eurotiales, Cladosporiales, Hypocreales, Mycosphaerellales, and Diaporthales. There were eight orders of the Basidiomycota dominated by Polyporales, Hymenochaetales, Agaricales, and Wallemiales. A principal component analysis was performed to compare abundance and correlation between the fungal communities, sampling locations and coral species. The results showed that the dissimilarity of fungal communities corresponded to geographic localities. On the other hand, there was a considerable overlap between the fungal communities of different coral species. The results from this research provide information on the diversity and ecology of the fungal communities associated with scleractinian corals in the Gulf of Thailand.","PeriodicalId":9191,"journal":{"name":"Botanica Marina","volume":"71 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2023-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67300876","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results from the limited research available on the effects of salinity and temperature on growth and reproduction of chytrids were inconclusive. This study investigated the combined effects of salinity (0, 1, 2, 4, 8, 16, 32) and temperature (17, 24, 30 °C) on the growth rate of Alphamyces chaetifer (isolates IMB230, IMB231, IMB232) and Gorgonomyces haynaldii (IMB233, IMB237, IMB239) cultured from low-salinity water samples collected from coastal wetlands/ponds of eastern Taiwan. All isolates grew well at salinity 4 or below, irrespective of the incubation temperatures, although some grew significantly faster at 30 °C. No growth was observed at salinity 16 or 32. At or below 4, A. chaetifer IMB230 and IMB231, isolated from the same collection site where salinity was 2, produced the fastest growth rate at these salinities while G. haynaldii IMB237 and IMB239, isolated from water samples of zero salinity, had the slowest growth rate. These results agree with previous research that chytrids are sensitive to salinity, and may explain why only 27 culturable Chytridiomycota species and allied taxa have been documented from the marine environment.","PeriodicalId":9191,"journal":{"name":"Botanica Marina","volume":"66 1","pages":"345 - 352"},"PeriodicalIF":2.2,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41621807","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In central Chile, Mazzaella laminarioides extends throughout the intertidal rocky zones, where blades are reported to grow up to 20 cm in length. Nevertheless, in low rocky intertidal zones with sand-influence, blades are noticeably larger than in other shores without sand effect. The aim of this study was to compare the morphology of M. laminarioides blades from two different conditions. Blades collected from four sites with, and four without, sand-influence were evaluated with traditional morphometry. Results showed that blades were longer and wider in sand-influenced sites. Sand abrasion was not directly evaluated, but indirect effects such as the abundance of bare rock and of sand tolerant species were higher in areas with sand-influence. Also, long blades were restricted to sand-influenced sites, supporting the relation between these two variables. Molecular analyses using the COI marker confirmed large-bladed individuals as M. laminarioides. Results indicated that life cycle phase, seasonality and vertical height were not related to large blades. We suggest that restriction of large blades to sand-influenced sites may be related to the healing processes of basal holdfasts after suffering sand abrasion.","PeriodicalId":9191,"journal":{"name":"Botanica Marina","volume":"66 1","pages":"165 - 179"},"PeriodicalIF":2.2,"publicationDate":"2023-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43719094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some Gracilaria species are difficult to identify morphologically and molecular phylogenetic data hold a key role in species level identification. In this study, the chloroplast genomes of G. changii and G. salicornia from the Peninsular Malaysia were sequenced to compare with the published taxa in order to gain a better understanding of the phylogenetic questions regarding the red algae, particularly G. changii and G. firma. Phylogenetic analysis for 66 plastid genes showed that G. changii from Malaysia formed a sister lineage with G. firma with a genetic distance of 0.43 %. However, there was a genetic distance of p = 4.32 % between the Malaysian and Philippine samples of G. changii, indicating they are genetically distinct. Five chloroplast genes (petF, rps12, rps14, rpl18 and petB) showed higher variation of genetic distance between Malaysian G. changii and G. firma (p = 1.23–2.00 %) and the intraspecific variation in G. salicornia from Peninsular Malaysia and Hawaii varies from p = 0–0.31 %. The lack of overlap between the intraspecific genetic distance of Malaysian G. changii and interspecific genetic distance of Malaysian G. changii-G. firma indicates that G. changii and G. firma are not conspecific.","PeriodicalId":9191,"journal":{"name":"Botanica Marina","volume":"66 1","pages":"191 - 199"},"PeriodicalIF":2.2,"publicationDate":"2023-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42203356","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
