[Ab] Resumo:The Kuroshio Current intrudes in the bottom layer of the East China Sea continental shelf from the northeast of Taiwan via two bottom branches named the Nearshore Kuroshio Branch Current (NKBC, along the 60 m isobath) and the Offshore Kuroshio Branch Current (OKBC, along the 100 m isobath). However, knowledge on the macrofaunal responses to these bottom branches is limited. This study examined the variations in the benthic macrofaunal community in a section of the East China Sea under the influence of the NKBC. Seven sites corresponding to three regions (the west, middle and east region) were sampled using an Agassiz trawl net at a monthly rate from February to November 2015 (except in August). A total of 270 macrofaunal species were collected in this study. Cluster analysis and nMDS ordination revealed three communities: the inshore, Kuroshio and offshore communities, roughly corresponding to the west, middle and east of NKBC route. Significant differences in the species composition (one-way PERMANOVA) and diversity indices (one-way ANOVA) among the regions and communities were observed, while no statistically significant difference among the months was detected. The indicator species also varied among the communities, with Sternaspis scutata and Odontamblyopus rubicundus dominating the inshore community, Camatopsis rubida, Schizaster lacunosus and Craspidaster hesperus dominating the Kuroshio community, and Portunus argentatus, Champsodon snyderi and Coelorinchus multispinulosus dominating the offshore community. Some rare species (e.g., Neobythites sivicola) may indicate the passage of the NKBC better than the indicator species. A redundancy analysis was used to describe the relationship between the macrofaunal species and environmental variables in this study. Water depth and turbidity played important roles in the distribution of the macrofauna. S. scutata and O. rubicundus were associated with high turbidity and shallow depth, while Plesionika izumiae and P. argentatus were associated with low turbidity and deep depth. This study outlines the impact of the NKBC on the distribution patterns of the macrofaunal community of the East China Sea. More studies are needed to understand the detailed interactions between macrofauna and the NKBC in the future.

[Ti] Título:A user-friendly tool to evaluate the effectiveness of no-take marine reserves.

[Ab] Resumo:Marine reserves are implemented to achieve a variety of objectives, but are seldom rigorously evaluated to determine whether those objectives are met. In the rare cases when evaluations do take place, they typically focus on ecological indicators and ignore other relevant objectives such as socioeconomics and governance. And regardless of the objectives, the diversity of locations, monitoring protocols, and analysis approaches hinder the ability to compare results across case studies. Moreover, analysis and evaluation of reserves is generally conducted by outside researchers, not the reserve managers or users, plausibly thereby hindering effective local management and rapid response to change. We present a framework and tool, called "MAREA", to overcome these challenges. Its purpose is to evaluate the extent to which any given reserve has achieved its stated objectives. MAREA provides specific guidance on data collection and formatting, and then conducts rigorous causal inference analysis based on data input by the user, providing real-time outputs about the effectiveness of the reserve. MAREA's ease of use, standardization of state-of-the-art inference methods, and ability to analyze marine reserve effectiveness across ecological, socioeconomic, and governance objectives could dramatically further our understanding and support of effective marine reserve management.

[Ab] Resumo:A new procedure using polyethersulfone (PES) microextraction followed by liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis was developed in this work for the simultaneous determination of 41 multiclass priority and emerging organic pollutants including herbicides, hormones, personal care products, and pharmaceuticals, among others, in seawater, wastewater treatment plant (WWTP) effluents, and estuary samples. The optimization of the analysis included two different chromatographic columns and different variables (polarity, fragmentor voltage, collision energy, and collision cell accelerator) of the mass spectrometer. In the case of PES extraction, ion strength of the water, pH, addition of EDTA, and the amount of the polymeric material were thoroughly investigated. The developed procedure was compared with a previously validated one based on a standard solid-phase extraction (SPE). In contrast to the SPE protocol, the PES method allowed a cost-efficient extraction of complex aqueous samples with lower matrix effect from 120 mL of water sample. Satisfactory and comparable apparent recovery values (80-119 and 70-131%) and method quantification limits (MQLs, 0.4-26 and 0.2-23 ng/L) were obtained for PES and SPE procedures, respectively, regardless of the matrix. Repeatability values lower than 27% were obtained. Finally, the developed methods were applied to the analysis of real samples from the Basque Country and irbesartan, valsartan, acesulfame, and sucralose were the analytes most often detected at the highest concentrations (51-1096 ng/L). Graphical abstract Forty-one multiclass pollutant determination in environmental waters by means of PES/SPE-LC-MS/MS.

[Ab] Resumo:The aim of this study was to compare imposex and butyltin compounds (BTs) data, collected before and after the organotin ban in 2008, in order to assess temporal and spatial variation of the phenomenon, the decline of BT contamination, and the effects on Hexaplex trunculus population in the coastal area of the northern Adriatic Sea, close to the Venice Lagoon. Both in marine and in lagoon sites, the results obtained in 2013-2015 showed a significant decline in the incidence of imposex in respect to those from the 2002 survey. In 2002, lagoon samples exhibited Relative Penis Size Index (RPSI) higher than marine samples, whereas no differences were detected in the recent survey, when all RPSI values were below 0.6%. Vas Deference Sequence Index (VDSI) mean values were over 4 before the ban introduction and below this value after that, indicating more critical conditions for gastropod population in 2002 rather than in 2013-15. Percentage of sterile females was up to 69% in 2002, whilst in the more recent survey no sterile female was found. Range of BT concentrations in gastropods decreased from 252 to 579 to 16-31ng∑BT/g d.w. BT body burdens varied according to a gender dependant pattern, with higher concentrations observed in females than in males. A first attempt to propose a classification based on BT impact on H. trunculus, according to the Water Framework Directive, revealed that most sites were in Bad ecological status before the ban and attained a Poor/Moderate status after that.

[Ab] Resumo:Copper pyrithione (CuPT) is a biocide, used worldwide to prevent biofouling on submerged surfaces. In aquatic environments it rapidly degrades, however, one of the degradation products (HPT) is known to react with cupric ion back to its parent compound. Not much is known about the behavior and toxicity of CuPT and its degradation product HPT in different water systems. Hence, our aim was to investigate the ecotoxicity of CuPT, HPT as well as Cu to the brine shrimp Artemia salina in natural seawater and organic matter-free artificial seawater. Moreover, in order to elucidate the influence of ionic strength of water on CuPT toxicity, tests were performed in water media with modified salinity. The results showed that CuPT was the most toxic to the exposed crustaceans in a seawater media with the highest salinity and with no organic matter content. HPT in a presence of cupric ion converted to CuPT, but the measured CuPT concentrations and the mortality of A. salina in natural water were lower than in artificial water. The toxicity of CuPT to A. salina was significantly influenced by the organic matter content, salinity, and proportions of constituent salts in water. In a combination with cupric ion, non-hazardous degradation product HPT exhibits increased toxicity due to its rapid transformation to its parent compound.

[Ab] Resumo:A Gram-stain-variable, aerobic, rod-shaped, motile and spore-forming bacterial strain, designated CJ11 , was isolated from a tidal flat sediment sample from Ganghwa-do, Republic of Korea. Strain CJ11 grew optimally on R2A at 30 °C and pH 7.0. Sequencing results of the 16S rRNA gene revealed that strain CJ11 possesses two copies of the 16S rRNA gene varying at five nucleotide positions. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain CJ11 belonged to the genus Paenibacillus within the family Paenibacillaceae and was most closely related to Paenibacillus lacus KCTC 33691 (99.36-99.15 % similarity). DNA-DNA relatedness levels of strain CJ11 was 41.7 % (reciprocal, 57.8 %) to P. lacus KCTC 33691 . The G+C content of the genomic DNA was 51.0 mol%. Strain CJ11 contained meso-diaminopimelic acid in the cell-wall peptidoglycan. The major isoprenoid quinone was menaquinone-7. The major cellular fatty acids were anteiso-C15 : 0, C16 : 0 and iso-C16 : 0. The predominant polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, two unidentified phospholipids, an unidentified glycolipid and several unidentified lipids. On the basis of the polyphasic taxonomic study, strain CJ11 represents a novel species in the genus Paenibacillus, for which the name Paenibacillustranslucens sp. nov. is proposed. The type strain is CJ11 (=KACC 19304 =JCM 32080 ).

[Ab] Resumo:A novel Gram-stain-negative, strictly aerobic, non-flagellated and rod-shaped bacterium, designated HF004 , was isolated from a marine sediment sample collected from the coast of Weihai, China. The strain grew optimally at 28 °C, pH 7.5-8.0 and in the presence of 2.0-3.0 % (w/v) NaCl. Based on the 16S rRNA gene sequence analysis, strain HF004 was a member of the genus Halioglobus, appearing to be closely related to Halioglobus pacificus (96.1 %) and Halioglobus japonicus (95.6 %). The major fatty acids were summed feature 3 (i.e. C16 : 1ω7c and/or iso-C15 : 0 2-OH), C17 : 1ω8c and C18 : 1ω7c. The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylglycerol. The predominant respiratory quinone was Q-8. The DNA G+C content was 57.2 mol%. Cells of strain HF004 were rod-shaped and formed circular, mucous and beige-pigmented colonies on marine agar after incubation for 72 h at 28 °C. On the basis of phenotypic, genotypic and phylogenetic evidence, strain HF004 is presented as a novel species, for which the name Halioglobus lutimaris sp. nov. is proposed. The type strain is HF004 (=KCTC 42395 =MCCC 1H00127 ).

[Ab] Resumo:A rod-shaped, Gram-staining-negative, strictly aerobic, non-motile bacterium with no flexirubin-type pigment, designated as W201E , was isolated from an intertidal sandy beach in Antarctica. The organism formed faintly yellow, round colonies on marine agar 2216E. The strain required sea salts for growth and grew optimally in the presence of 2 % (w/v) NaCl at pH 7.0, 20 °C. Phylogenetic analysis based on 16S rRNA gene sequence indicated that strain W201E belonged to the genus Flavobacterium and showed the highest sequence similarity to Flavobacterium algicola NBRC 102673 (96.5 %). The major respiratory quinone was menaquinone 6, and the predominant fatty acids were iso-C15 : 1 G, iso-C15 : 0, iso-C15 : 0 3-OH and summed feature 3 (which comprises C16 : 1ω7c and/or C16 : 1ω6c). The polar lipids of strain W201E comprised one phosphatidylethanolamine, two unidentified aminolipids and three unidentified polar lipids. The DNA G+C content of strain W201E was 34.1 mol%. On the basis of the polyphasic analyses, this isolate was considered to represent a novel species in the genus Flavobacterium, for which the name Flavobacterium ovatum sp. nov. is proposed. The type strain is W201E (=KCTC 52693 =MCCC 1K03251 =CGMCC 1.16053 ).

[Ab] Resumo:A Gram-staining-negative, aerobic, non-motile, rod-shaped bacterium, designated as P308H10 , was isolated from surface sediment of the Southern Indian Ocean. Growth occurred at 4-36 °C (optimum 20-25 °C), pH 6.0-8.5 (optimum 7.5-8.0) and in the presence of 1-8 % (w/v) NaCl (optimum 2-3 %). Phylogenetic analysis based on 16S rRNA gene sequences showed that strain P308H10 lies within the clade of members of the genus Arenibacter and is closely related to Arenibacterhampyeongensis HP12 (98.0 %), Arenibacterechinorum KMM 6032 (98.4 %), Arenibacterpalladensis LMG 21972 (97.9 %), Arenibactertroitsensis KMM 3674 (97.9 %) and 'Arenibacter algicola' TG409 (98.1 %). The average nucleotide identity and digital DNA-DNA hybridization values between strain P308H10 and the five reference strains were 85.9-80.6 % and 30.2-23.6 %, respectively. The major fatty acids (>10 %) of strain P308H10 were summed feature 3, iso-C17 : 0 3-OH, iso-C15 : 1 G and iso-C15 : 0. The major polar lipids comprised phosphatidylethanolamine, five unidentified aminolipids and four unidentified lipids. The only respiratory quinone was menaquinone-6. The genomic DNA G+C content was 38.2 mol%. On the basis of the phenotypic, phylogenetic and chemotaxonomic data presented, strain P308H10 represents a novel species of the genus Arenibacter, for which the name Arenibacter catalasegens sp. nov. is proposed. The type strain is P308H10 (=GDMCC 1.1230 =KCTC 52983 ). An emended description of the genus Arenibacter is also proposed.

[Ab] Resumo:A heterotrophic, Gram-stain-negative, aerobic, sodium-requiring and motile bacterium was isolated from oil-contaminated surface water of the Gulf of Mexico during the Deepwater Horizon oil spill. Strain O3.65 showed highest 16S rRNA gene sequence similarity to Phaeobacter gallaeciensis BS107 and Phaeobacter inhibens T5 , both with 98.3 %, respectively. Based on complete genome analysis, highest similarity was observed to species of the genus Ruegeria. Strain O3.65 exhibited a broad salinity, temperature and pH range of 0.5-10 % NaCl, 4-45 °C and 5.5-9.0, respectively. The DNA G+C content of strain O3.65 was 61.5 mol%. The major respiratory lipoquinone was ubiquinone-10 (Q-10), the most dominant fatty acids (>1 %) comprised 18 : 1ω7c and 18 : 1ω7c 11-methyl, 10 : 0 3OH, 12 : 1 3OH, 14 : 1 3OH/3-oxo-14 : 0, 16 : 0, 16 : 0 2OH, 18 : 1 2OH and 12 : 1. The polar lipid pattern indicated presence of phosphatidylcholine, phosphatidylglycerol, an unidentified aminolipid, two unidentified phospholipids and seven unidentified lipids. On Difco marine broth agar, strain O3.65 formed smooth, shiny white to beige and convex colonies with regular edges. Phylogenetic, phylogenomic and phenotypic differences revealed that strain O3.65 represents a new species of a novel genus within the family Rhodobacteraceae, for which we propose the name Tritonibacter horizontis gen. nov., sp. nov. The type strain of the type species is O3.65 (=DSM 101689 =LMG 29740 ).
