The pollution of antibiotics commonly existed throughout the entire aquaculture process,but the residues of antibiotics at different aquaculture stages have rarely been studied.This study investigated the occurrence,distribution and risk assessment of antibiotics at different aquaculture stages (the non-aquaculture stage,the early aquaculture stage,the middle aquaculture stage,and the late aquaculture stage) in two typical marine aquaculture areas(Mahegang River and Dingzi Bay) surrounding the Yellow Sea.Fluoroquinolones and tetracyclines were commonly used antibiotics in the aquaculture of these areas with high detection frequencies (17%to 83%).Compared among four aquaculture stages,the highest concentration of antibiotics (9032.08 ng/L) in aquaculture ponds was detected at the late aquaculture stage.And the antibiotic pollution level of natural water was directly related to the aquaculture stages.Similarly,at the aquaculture stages,the detection frequency of antibiotics in sediments was higher than that at the non-aquaculture stage.Based on the correlation analysis,the concentration of main antibiotics in water showed a positive correlation with total nitrogen (p<0.05) and chlorophyll a (p<0.01),while it showed a negative correlation with salinity (p<0.01) in coastal water of the Dingzi Bay.According to the risk assessment,with the development of aquaculture stages,the selection pressure of fluoroquinolones and tetracyclines on resistant bacteria had increased.And the ecological risks caused by sulfonamides and tetracyclines to aquatic organisms had also increased markedly.Overall,this study may provide a reference for formulating regulatory policies regarding antibiotic use at different aquaculture stages.

Although most fishes are ectothermic,some,including tuna and billfish,achieve endothermy through specialized heat producing tissues that are modified muscles.How these heat producing tissues evolved,and whether they share convergent molecular mechanisms,remain unresolved.Here,we generated a high-quality genome from the mackerel tuna(Euthynnus affinis)and investigated the heat producing tissues of this fish by single-nucleus and bulk RNA sequencing.Compared with other teleosts,tuna-specific genetic variation is strongly associated with muscle differentiation.Single-nucleus RNA-seq revealed a high proportion of specific slow skeletal muscle cell subtypes in the heat producing tissues of tuna.Marker genes of this cell subtype are associated with the relative sliding of actin and myosin,suggesting that tuna endothermy is mainly based on shivering thermogenesis.In contrast,cross-species transcriptome analysis indicated that endothermy in billfish relies mainly on nonshivering thermogenesis.Nevertheless,the heat producing tissues of the different species do share some tissue-specific genes,including vascular-related and mitochondrial genes.Overall,although tunas and billfishes differ in their thermogenic strategies,they share similar expression patterns in some respects,highlighting the complexity of convergent evolution.

Both natural and synthetic peptides are not only biologically important,continuous research and comprehension of these short protein fragments show that they also have multifarious potentials in food manufacturing,namely emulsion-based products.The emulsions may basically be oil-in-water or water-in-oil,as well as temporary,semi-permanent,or permanent in a continuous phase that suspends the droplets of the other elements used in food and pharmaceutical industries to formulate products such as gels,creams,ointments,and vaccines.In this review,the classification,preparation,and identification of peptides were described,followed by peptide-based emulsion properties and their relationship with regards to stability,structure,solubility,hydrophobicity,foaming,and water holding capacity.This then dovetailed into the release rate and gastric stability of encapsulated peptides in the human digestive system,before exploring further needs and recommendations.It is desired that more studies be conducted to define the impact of carrier ingredients selection,encapsulation and processing techniques,environment,and peptides chemistry on peptide-based emulsions to attain high efficacy.

Microorganisms in sediments are critical to marine ecosystems.The microbial communities in marine sediments of the Bohai Sea(BS)and Yellow Sea(YS),the eastern Chinese marginal seas,were uncovered in employing the metagenomic approach.In addition,the taxonomic and functional compositions of microbes were compared among various sediment core depths.Results showing the compositions,diversities,and functions of the microbial communities showed no significant variations with sea areas,and significant seasonal variations was observed in station 3500-7 only on functions of the microbial communities.Moreover,the compositions,diversities,and functions of the microbial communities changed noticeably in different sediment depths in close correlation with physical and chemical properties of sediments.However,the large fraction of the variation in functional communities remained unexplained.From bioinformatic analysis of the metagenomic data,the carbon-metabolismrelated genes such as glycosyl transferase(GT),glycoside hydrolase(GH),and carbohydrate esterase(CE)genes were rich in the microbial community,especially in the top sediment depth.Additionally,in this N-polluted habitat,nitrification and anaerobic ammonia oxidation(anammox)were dominant in the top sediment depth,whereas dissimilatory nitrate reduction to ammonium(DNRA)and denitrification were dominant in the middle and bottom depth,respectively.Further identification of possible biogeochemical links suggested that Gammaproteobacteria,Alphaproteobacteria,Nitrospirae,Nitrospinae,Chloroflexi,and Methanomicrobia might promote effective circulation of carbon and nitrogen cycling.This study expanded our knowledge about the structure and functional potential of microbial communities associated with different sediment depth,and provided further comprehensive information on element cycles in marine environments.

As key parts of land-sea transition zones,estuary ecosystems play a very important role in the ocean carbon cycle processes.The sources,degradation,and preservation of dissolved organic matter(DOM)in estuaries have long been the subject of intense study.To examine the aforementioned issues,this study examined three-dimensional fluorescence spectroscopy and ultraviolet-visible absorption spectroscopy to determine the spatial distribution and sources of DOM in the pore water of three sedimentary cores from the Pearl River Estuary(S1,S2 and S3,with increasing salinity).Using the parallel factor analysis(PARAFAC)method to analyze the three-dimensional fluorescence spectrum data,five fluorescent components were obtained—three humic-like components(C1,C3,and C4),and two protein-like components(C2 and C5).C2 exhibited a significant positive correlation with the sediment microbial deoxyribose nucleic acid(DNA)concentration(R~2=0.69,P<0.01),indicating that the protein-like component C2 might be derived from the catabolism of in situ microbes.C5 displayed a relatively weak correlation with DNA concentration(R~2=0.40,P<0.05),presumably due to the incorporation of phenolic compounds,which have a fluorescence peak very similar to that of protein-like components.The source of humic-like fluorescent components is extremely complex.The content at station S1 was relatively high(1.45–8.83 R.U.),which implies that terrestrial inputs had a significant influence.The three humic-like components showed similar distributions at S2 and S3,and the fluorescence intensity was rather low;this result indicates that the DOM at these two stations was more likely affected by the metabolism of algae and microorganisms.The humification index(HIX)and the fluorescence intensity of protein-like components increased and decreased,respectively,with depth.There was a significant positive correlation between the relative content of protein-like components and the spectral slope ratio(SR),which indicates that DOM transitioned from low-molecular-weight pro

The anode activity can to a great degree limit the cathodic hydrogen evolution efficiency in an electrolyte cell.Thus,cost-efficient electrocatalysts with good water oxidation performance and stability are highly desired in widespread implementation of the hydrogen production from water splitting.This paper proposes a facile corrosion-reconstruction strategy to transform Fe surface into a Fe-Co hydroxide layer to improve the oxygen evolution activity.The as-prepared catalyst was measured to have an over-potentential as low as 320 mV at 100 mA·cm^(−2),and its stability even exceeded 600 h.Surface and Raman spectroscopy analyses indicated that the catalyst experienced chemical changes from hydroxides to oxyhydroxides and Co^(2+)to Co^(3+)during oxygen evolution reaction(OER).The corrosion-reconstruction is not only an economical method to synthesize a highly efficient,stable and durable Fe-based catalysts,it also converses the detrimental corrosion into a beneficial catalyst fabrication process.

The world’s coral reefs are threatened by the cumulative impacts of global climate change and local stressors.Driven largely by a desire to understand the interactions between corals and their symbiotic microorganisms,and to use this knowledge to eventually improve coral health,interest in coral microbiology and the coral microbiome has increased in recent years.In this review,we summarize the role of the coral microbiome in maintaining a healthy metaorganism by providing nutrients,support for growth and development,protection against pathogens,and mitigation of environmental stressors.We explore the concept of coral microbiome engineering,that is,precise and controlled manipulation of the coral microbiome to aid and enhance coral resilience and tolerance in the changing oceans.Although coral microbiome engineering is clearly in its infancy,several recent breakthroughs indicate that such engineering is an effective tool for restoration and preservation of these valuable ecosystems.To assist with identifying future research targets,we have reviewed the common principles of microbiome engineering and its applications in improving human health and agricultural productivity,drawing parallels to where coral microbiome engineering can advance in the not-too-distant future.Finally,we end by discussing the challenges faced by researchers and practitioners in the application of microbiome engineering in coral reefs and provide recommendations for future work.

With the gradual maturity of sequencing technology,many microbiome studies have published,driving the emergence and advance of related analysis tools.R language is the widely used platform for microbiome data analysis for powerful functions.However,tens of thousands of R packages and numerous similar analysis tools have brought major challenges for many researchers to explore microbiome data.How to choose suitable,efficient,convenient,and easy-to-learn tools from the numerous R packages has become a problem for many microbiome researchers.We have organized 324 common R packages for microbiome analysis and classified them according to application categories(diversity,difference,biomarker,correlation and network,functional prediction,and others),which could help researchers quickly find relevant R packages for microbiome analysis.Furthermore,we systematically sorted the integrated R packages(phyloseq,microbiome,microbiomeAnalystR,Animalcules,microeco,and amplicon)for microbiome analysis,and summarized the advantages and limitations,which will help researchers choose the appropriate tools.Finally,we thoroughly reviewed the R packages for microbiome analysis,summarized most of the common analysis content in the microbiome,and formed the most suitable pipeline for microbiome analysis.This paper is accompanied by hundreds of examples with 10,000 lines codes in GitHub,which can help beginners to learn,also help analysts compare and test different tools.This paper systematically sorts the application of R in microbiome,providing an important theoretical basis and practical reference for the development of better microbiome tools in the future.All the code is available at GitHub ***/taowenmicro/EasymicrobiomeR.

Currently,new species of freshwater fish trypanosomes,which are economically important parasites,are being described based on subjectively selected features,i.e.,their cell morphology and the host species.We have performed detailed phylogenetic and haplotype diversity analyses of all 18S rRNA genes available for freshwater fish trypanosomes,including the newly obtained sequences of Trypanosoma carassii and Trypanosoma danilewskyi.Based on a sequence similarity of 99.5%,we divide these trypanosomes into 15 operational taxonomic units,and propose three nominal scenarios for distinguishing T.carassii and other aquatic trypanosomes.We find evidences for the existence of a low number of freshwater fish trypanosomes,with T.carassii having the widest geographic and host ranges.Our analyses support the existence of an umbrella complex composed of T.carassii and two sister species.

Great advancement has been made on natural gas hydrates exploration and test production in the northern South China Sea.However,there remains a lot of key questions yet to be resolved,particularly about the mechanisms and the controls of gas hydrates enrichment.Numerical simulaution would play signficant role in addressing these questions.This study focused on the gas hydrate exploration in the Shenhu Area,Northern South China Sea.Based on the newly obtained borehole and multichannel reflection seismic data,the authors conducted an integrated 3D basin modeling study on gas hydrate.The results indicate that the Shenhu Area has favorable conditions for gas hydrate accumulation,such as temperature,pressure,hydrocarbon source,and tectonic setting.Gas hydrates are most concentrated in the Late Miocene strata,particularly in the structual highs between the Baiyun Sag and the Liwan Sag,and area to the south of it.It also proved the existence of overpressure in the main sag of source rocks,which was subject to compaction disequilibrium and hydrocarbon generation.It also shown that the regional fault activity is not conducive to gas hydrate accumulation due to excess gas seepage.The authors conjecture that fault activity may slightly weaken overpressure for the positive effect of hydrocarbon expulsion and areas lacking regional fault activity have better potential.
