However, there is still a gap in this field regarding how to efficiently sample larvae, particularly in warm and nutrient-poor waters. We evaluated the differences found in larvae caught with two mesh size nets (330 and 500 μm) sampled in the open ocean: shelf break and slope (equatorial SW Atlantic). In total, 792 larvae were sampled, representing 14 orders and 55 families. Overall, larval density was low, and no difference in density was detected between the two net sizes (ind.100 m−3). However, a greater number of taxa (46 families) were found in the smaller net (300 μm) than in the larger (500 μm) (37). Moreover, 30.2% of families were found only in the 330 μm net, whereas 9.4% were found only in the 500 μm net. A total of 60.4% of taxa were common to both nets. Gonostomatidae, Paralepididae, Scombridae, Carangidae, Phosichthyidae, and the reef-associated families Scaridae and Gobiidae were the most abundant taxa in the smaller net. In contrast, Myctophidae, Gobiidae, Gonostomatidae, and Stomiidae were the most abundant in the larger net. We highlight mesophotic reefs and seamounts in the South Atlantic for adult spawning and larval growth, emphasizing the need for conservation actions and appropriate fisheries management. Finally, our results also indicate that the combination of different mesh net sizes provides a better baseline of fish larval diversity in warm and oligotrophic oceans.","PeriodicalId":18201,"journal":{"name":"Marine Biodiversity","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2024-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139763753","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 need for studies to assess its short- and long-term consequences on polymetallic nodule ecosystems is therefore also increasingly prescient. Recent image-based expedition studies have described the temporal impacts on epi-/megafauna seafloor communities across these ecosystems at particular points in time. However, these studies have failed to capture information on large infauna within the sediments or give information on potential transient and temporally limited users of these areas, such as mobile surface deposit feeders or fauna responding to bloom events or food fall depositions. This study uses data from the Peru Basin polymetallic nodule province, where the seafloor was previously disturbed with a plough harrow in 1989 and with an epibenthic sled (EBS) in 2015, to simulate two contrasting possible impact forms of mining disturbance. To try and address the shortfall on information on transient epifauna and infauna use of these various disturbed and undisturbed areas of nodule-rich seafloor, images collected 6 months after the 2015 disturbance event were inspected and all Lebensspuren, ‘traces of life’, were characterized by type (epi- or infauna tracemakers, as well as forming fauna species where possible), along with whether they occurred on undisturbed seafloor or regions disturbed in 1989 or 2015. The results show that epi- and endobenthic Lebensspuren were at least 50% less abundant across both the ploughed and EBS disturbed seafloors. This indicates that even 26 years after disturbance, sediment use by fauna may remain depressed across these areas.","PeriodicalId":18201,"journal":{"name":"Marine Biodiversity","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2024-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139763754","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 genus Alitta, of the family Nereididae, comprises nine recognized species, including Alitta succinea, considered cosmopolitan. The species was first described from the Helgoland (Germany) and has been recorded on the Brazilian coast. However, evidence suggests that A. succinea might be a complex of cryptic species. The aim of this short communication is molecularly analyzing specimens of Alitta succinea to ascertain the status of the species in Brazil. The study encompassed molecular analyses of COI and 16S sequences using data obtained from eight specimens collected from three localities at Rio de Janeiro and seven specimens collected from Santa Catarina, in addition to available data from GenBank and BOLD Systems. Molecular analyses clustered specimens from Brazil, the type locality and other localities in the same clade, reinforcing the status of A. succinea as an invasive species. However, additional studies, including more extensive molecular and morphological analyses, are necessary to clarify the distribution of the Alitta succinea along the Brazilian coast.","PeriodicalId":18201,"journal":{"name":"Marine Biodiversity","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2024-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139763813","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}

In Puerto Rico, SCTLD was first reported in 2019 off the east coast, spreading to the north-central region by early February 2021. Benthic surveys were conducted at Cueva del Indio (CI) and Peñón de Mera (PM) off Arecibo to (1) quantify coral species-specific SCTLD prevalence using four 10 × 1-m2 belt transects and (2) acquire time-series photo and video surveys to illustrate the impact of SCTLD, to evaluate coral species-specific susceptibilities, and estimate the timing of onset in Arecibo. A total of 650 corals in six species (Pseudodiploria strigosa, P. clivosa, Montastraea cavernosa, Siderastrea siderea, Orbicella annularis, Porites astreoides) were recorded inside the belt transects at both sites. SCTLD prevalence varied between 54% (P. strigosa) and 35.5% (M. cavernosa) at CI, and between 87.5% (S. siderea) and 25% (O. faveolata) at PM. Photo/video surveys revealed that SCTLD caused partial mortality in 11 species and full mortality in P. strigosa, P. clivosa, S. siderea, M. cavernosa, and Dendrogyra cylindrus. The results are discussed in view of prior research and contribute to understanding the spread and impact of SCTLD around Puerto Rico, which can be applied to predict its spread to other regions in the Caribbean.","PeriodicalId":18201,"journal":{"name":"Marine Biodiversity","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139668024","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}

Fishing pressure on the near threatened fish Harpadon nehereus has recently increased, leading to the aging and miniaturization of its population. We determined the gene sequences of mitochondrial cytochrome b (Cytb) and nuclear recombination-activating 1 (RAG1) in eight populations of H. nehereus in the Northwest Pacific, analyzed their genetic diversity levels, and compared the effectiveness of these two markers for analyzing genetic diversity and population structure. Sequence analysis of Cytb revealed that the eight populations showed low haplotype diversity (Hd = 0.110–0.356) and low nucleotide diversity (pi = 0.00015–0.00053). No significant genetic differentiation was observed among the populations (Fst = − 0.0197–0.000, P > 0.05). The haplotype network diagram did not exhibit evident geographical clustering or a pedigree structure. Molecular variance analysis revealed that variation primarily occurred within populations. Further comparative analysis of the RAG1 and Cytb sequences revealed two differences. RAG1 showed high haplotype diversity (Hd = 0.780–0.900) and low nucleotide diversity (pi = 0.00355–0.00463). The genetic differentiation index value revealed a significantly low level of genetic differentiation among some populations.","PeriodicalId":18201,"journal":{"name":"Marine Biodiversity","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2024-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139589987","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}
