Yet, standardised 2D photographs and 3D scans provide important morphological information to accompany DNA-barcoded specimens for reference databases such as the Barcode of Life Data System (BOLD). Shelled pteropods are considered as bio-indicators to study impacts of ocean acidification, and thus, it is especially important to obtain high-quality records of their fragile aragonitic shells. We used alcohol-based hand sanitiser gel as a medium for photographing pteropods of the genus <i>Limacina</i> prior to micro-CT scanning and destructive DNA analysis. The high viscosity and transparency of the hand sanitiser enabled easy handling of the specimens so that they could be positioned in a standardised orientation and photographed with a stacking microscope. The high-quality photographs provide a record of morphology and allow for subsequent geometric morphometric analyses. This method did not impact the downstream micro-CT and molecular analyses of the same specimens and resulted in publicly available 2D and 3D digital vouchers as well as ten reference DNA barcodes (partial Cytochrome Oxidase I gene sequences). While alcohol-based hand sanitiser entered our daily lives due to a distressing pandemic, we could make use of it as a cheap and easily available resource to make high quality voucher photographs of shelled pteropods.

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 <i>Mytella strigata</i> and <i>Aetobatus ocellatus</i>, respectively. Our findings highlight the potential of a complementary multi-marker approach for biomonitoring invertebrates and vertebrates comprehensively across distinct habitats.</p>","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}

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}
