Bacterial community structure and the effects of several environmental factors on bacterial distribution were investigated in sediment macrophyte-dominated algae-dominated areas a large, shallow, eutrophic freshwater lake (Lake Taihu, China). Surface samples collected at 6 sampling sites (3 from each 2 areas) 15 February August 2009. Based cluster analysis DGGE banding patterns, there significant seasonal variations macrophyte- areas, site-specific variation within an area between areas....
Abstract Background River damming inevitably reshapes water thermal conditions that are important to the general health of river ecosystems. Although a lot studies have addressed damming’s impacts, most them just assess overall effects climate variation and human activities on dynamics. Less attention has been given quantifying impact variation, flow regulation, respectively. In addition, for rivers already faced an erosion problem in downstream channels, adjustment hydroelectric power plant...
Water-energy nexus has been a popular topic of rese arch in recent years. The relationships between the demand for water resources and energy are intense closely connected urban areas. primary, secondary, tertiary industry gross domestic product (GDP), total population, annual precipitation, agricultural industrial consumption, tap supply, discharge wastewater, daily sewage treatment capacity, electricity consumption coal enterprises above designed size were chosen as input indicators. A...
Rivers and their tributaries sculpt the earth's surface, play an important role in substance circulation energy flow. Bacteria are involved most biogeochemical processes fluvial ecosystem; however, pattern distribution a river its has not yet been investigated detail. In present study, high-throughput sequencing was employed to examine bacterial communities co-occurrence networks between Kaidu River nine northwestern China. The results obtained demonstrated that both shared similar dominant...
The middle and lower Yangtze Plain is a typical floodplain in which many lakes connect with each other, especially the wet season. More importantly, frequent change of regional water level season, there mutual hydrodynamic exchange among these lakes. microbial biogeography interconnected still poorly understood. This study aims to unravel mechanisms underlying assembly process abundant rare bacteria Plain. Our findings will provide deeper understanding biogeographic patterns bacterial taxa...
To investigate the effects of different habitats and plant growth status on abundance, biomass community structure epiphytic microbes, Potamogeton malaianus Miq. at two (Gonghu Bay East Taihu) in Lake Taihu were collected June, August November (corresponding to period development submerged macrophytes). The relative abundance major algae groups was determined with high performance liquid chromatography (HPLC), structures dynamics bacteria assessed by terminal restriction fragment length...
To reveal the effects of water diversion from Yangtze River to Lake Taihu on phytoplankton habitat main transfer channel Wangyu River, we investigated water’s physicochemical parameters and communities during non-diversion periods over winters between 2014–2016, respectively. During in winter 2014 2015, nutrients organic pollutant contents were significantly lower than those period 2016. Moreover, diversities relative proportions Bacillariophyta evidently increased winter. The increase...
Abstract The effect of decomposition Microcystis blooms on the sediment bacterial communities was investigated in a 14‐day mesocosm experiments under dark and anoxic condition with three differing levels spp. biomass (from 20 to 2000 µg L −1 ) as measured by chlorophyll‐ (Chl‐ concentration water column. Sediment samples were collected days 0 14 for community composition (BCC) analysis, based rapid decreases Chl‐ BCC determined denaturing gradient gel electrophoresis sequencing predominant...
Oligosaline lakes in arid regions provide indispensable water resources for humans; however, information on the bacterial community composition (BCC) of this ecosystem is limited. In present study, we explored seasonal and vertical variations BCC Lake Bosten, a unique oligosaline lake (1.2‰ salinity) arid, northwestern China, using denaturing gradient gel electrophoresis 16S rRNA gene sequencing. We obtained 544 clones 98 operational taxonomic units (OTUs) from six clone libraries. The top...
We analyzed the composition and diversity of a bacterial community to determine its response increasing salinity in Xiangsi Lake wetland arid region northwest China. studied 12 sites, ranging from freshwater saltwater habitats, using polymerase chain reaction (PCR)-based terminal restriction fragment length polymorphism (T-RFLP) sequencing 16S rRNA genes 5 selected samples. Cluster analysis phylogenetic revealed that changed significantly increased within small-scale (50.8 km(2)). Detailed...
气流作为湖泊、湿地等有限水域的主要驱动力之一，其演化特征是研究水-气间能量与物质传递的基础，决定了水域水环境与水生态格局，具有重要研究意义.采用室内风洞水槽，通过设置不同试验风速，研究近水面气流与风速和吹程的响应关系与演化特征，并将光滑壁面条件下的气流特征作为试验对照组，分析时间域内风速垂向分布形式、摩阻风速、特征粗糙度等变化规律，剖析频率域内风速的主频变化与波致气流边界层厚度等参数的分布特征.结果表明：近水面时均风速符合对数分布，摩阻风速与特征粗糙度均与风速呈正相关，且同等风速与吹程条件下两者均大于光滑壁面条件，波致气流边界层厚度与风速和吹程均呈正相关.分析了采用风速作为气流动力参数存在不妥的原因，认为采用摩阻风速或切应力作为气流动力参数更具合理性，基于前人研究数据的统计分析，给出了特征粗糙度与风速、吹程和水深的回归关系式.探讨了气流-风浪“同频率”的互馈模式，发现波致气流边界层厚度不只与波长有关，还受波高、波周期和水深等多因素影响，建立了考虑风浪非线性特征的波致气流边界层厚度关系式.;As one of the main driving forces limited...
To expand current knowledge on the molecular aspects of alkaline phosphatase PhoX in shallow eutrophic freshwaters, we investigated genetic diversity and abundance PhoX-encoding gene (phoX) 4 ecological regions Lake Taihu, China, following a gradient total phosphorus concentrations ranging from hypereutrophic to mesotrophic. Bacterial phoX was heterogeneously distributed with highest mesotrophic Xukou Bay. The enzymatically hydrolyzable determined distribution bacterial Taihu. Most (70.8%)...
