Comprehensive eDNA characterization of marine metazoan biodiversity requires broad amplification of genetic markers or complementary loci to detect a wide diversity of taxa. In this study, we tested the effectiveness of the universal cytochrome c oxidase subunit I (COI) and marine vertebrate 16S ribosomal RNA markers to recover coastal marine taxa from eDNA samples collected along the urban coast of Singapore. We recovered 260 molecular operational taxonomic units (MOTUs) from a total of 12 L of water (triplicates of 1 L at each of four sites) with no overlap of MOTUs observed between the two assays despite the expectation that the COI primer set could potentially amplify a broad range of metazoans. Notably, our COI assay identified mainly invertebrates, while the 16S assay primarily recovered vertebrates. For the relatively new 16S barcoding marker, we applied two species delimitation programs on a curated, comprehensive vertebrate dataset to determine the distance threshold between intra- and interspecific comparisons (2%). Community analyses revealed that metazoan communities were distinct between sites for both assays. In addition, DNA metabarcoding was shown to be helpful for the monitoring of non-indigenous and threatened marine species, such as Mytella strigata and Aetobatus ocellatus, respectively. Our findings highlight the potential of a complementary multi-marker approach for biomonitoring invertebrates and vertebrates comprehensively across distinct habitats.","PeriodicalId":18201,"journal":{"name":"Marine Biodiversity","volume":"22 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2023-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138541107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The six known species of Berndtia are restricted to the tropical Western Pacific. We provide the first record of Berndtia from the hydrocoral Millepora exaesa Forsskål, 1775 from the central Red Sea, Saudi Arabia, and the scleractinian coral Coscinaraea cf. monile (Forsskål, 1775) from the Arabian Sea, Oman. These findings extend the known range and host use of the genus and raise questions about Berndtia’s host specificity. A molecular analysis of Saudi Arabian and Omani specimens suggests that they belong to two new lineages that may represent new species of Berndtia, each associated with multiple hosts. Further sampling around the Arabian Peninsula and the Western Indian Ocean and exploration of additional potential hosts would provide new insights into the species diversity of the genus.","PeriodicalId":18201,"journal":{"name":"Marine Biodiversity","volume":"26 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2023-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138541104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some general understanding of the consequences of shifting nutrient regimes can be derived from the detailed investigation of the phytoplankton community and its biodiversity. Here, we combined long-term monitoring datasets of German and Dutch coastal stations and amended these with additional information on species biomass. Across the integrated and harmonized dataset, we used multiple biodiversity descriptors to analyse temporal trends in the Wadden Sea phytoplankton. Biodiversity, measured as the number of species (S) and the effective number of species (ENS), has decreased in the Dutch stations over the last 20 years, while biomass has increased, indicating that fewer species are becoming more dominant in the system. However, biodiversity and biomass did not show substantial changes in the German stations. Although there were some differences in trends between countries, shifts in community composition and relative abundance were consistent across stations and time. We emphasise the importance of continuous and harmonized monitoring programmes and multi-metric approaches that can detect changes in the communities that are indicative of changes in the environment.","PeriodicalId":18201,"journal":{"name":"Marine Biodiversity","volume":"132 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135342380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
