| 1 | Significance of Vibrio species in the marine organic carbon cycle-A review显示文摘The genus Vibrio,belonging to Gammaproteobacteria of the phylum Proteobacteria,is a genetically and ecologically diverse group of heterotrophic bacteria,that are ubiquitous in marine environments,especially in coastal areas.In particular,vibrios dominate,i.e.up to 10%of the readily culturable marine bacteria in these habitats.The distribution of Vibrio spp.is shaped by various environmental parameters,notably temperature,salinity and dissolved organic carbon.Vibriospp.may utilize a wide range of organic carbon compounds,including chitin(this may be metabolized by most Vibrio spp.),alginic acid and agar.Many Vibrio spp.have very short replication times(as short as~10 min),which could facilitate them developing into high biomass content albeit for relatively short durations.Although Vibriospp.usually comprise a minor portion(typically^1%of the total bacterioplankton in coastal waters)of the total microbial population,they have been shown to proliferate explosively in response to various nutrient pulses,e.g.,organic nutrients from algae blooms and iron from Saharan dust.Thus,Vibrio spp.may exert large impacts on marine organic carbon cycling especially in marginal seas.Genomics and related areas of investigation will reveal more about the molecular components and mechanisms involved in Vibrio-mediated biotransformation and remineralization processes. | Xiaohua ZHANG Heyu LIN Xiaolei WANG Brian AUSTIN | 2018 | Science China Earth Sciences2018，61，10： | 5 |
| 3 | Applications of gravity data in identification of faults and tectonic boundaries of a working area in Inner Mongolia显示文摘In order to determine the tectonic framework of the Late Paleozoic sedimentary basin of the studied area in Inner Mongolia, horizontal derivative, vertical derivative, total gradient modulus, tilt angle, and Euler deconvolution methods were used to process the high-precision gravity data. Four major faults and six secondary faults have been identified according to the horizontal fault position information provided by the first four methods, and the fault depth information were obtained using the Euler deconvolution method. The interpreted faults were identified as the main basin-controlling structures in the study area, which was helpful for deepening the understanding of the basin's structure, as well as providing important references for delineating hidden polymetallic ore veins. | ZOU Bolun LI Tonglin WU Yangang WU Heyu SHI Jiaqiang LIN Baoze | 2019 | Global Geology2019，22，2： | 0 |
