Spatial and temporal distribution of nitrite-dependent anaerobic ammonium and methane oxidation bacteria in mangrove wetland [PDF]
, 2017 厌氧氨氧化（anaerobicammoniumoxidation，ANAMMOX）和反硝化型厌氧甲烷氧化（nitrite-dependentanaerobicmethaneoxidation，N-DAMO）反应是新发现的两类能够参与碳氮循环的微生物，它们的发现对完善全球碳氮循环理论具有重要意义。红树林湿地生态系统位于陆地和海洋交界处，周期性受海水浸淹，并且能够接受来自海洋和陆地的各种污染物，因此物质资源和生物资源都很丰富。同时，红树林湿地沉积物能够为ANAMMOX和N-DAMO微生物创造一个厌氧环境 ...

Shuitu Baochi Xuebao, 2018 通过向25年老龄苹果园土壤中施入不同浓度（T1，0.02‰；T2，0.1‰；T3，0.5‰）的棉隆，利用微生物平板培养、荧光定量PCR（qPCR）、微生物碳源利用（biolog-ECO）、末端限制性片段长度多态性（T-RFLP）、生物多样性指数Biodap等方法研究不同浓度棉隆熏蒸下土壤可培养微生物（细菌、真菌）数量、群落结构及其多样性指数随时间变化的演变趋势，并进行平邑甜茶盆栽验证，以期为减轻苹果连作障碍筛选棉隆浓度提供理论依据。结果表明：0.1 ...

野生动物学报, 1990 本文是7年对洪湖越冬野鸭的群落结构变化的研究结果;在洪湖统计捕获的野鸭有12种隶属于3属,野鸭个体密度大部分逐年下降,多样性指数和均匀性指数也趋向降低,七年平均11月至翌年3月野鸭个体密度,以12月和1月最大,11月和3月最小,野鸭一般9月迁来洪湖,翌年4月迁离。越冬野鸭多以集群方式活动,也常与骨顶鸡混合成群。鸟类的群落结构研究已在国内外有不少报导,本文是1981—1987年对洪湖越冬野鸭的种类、种群数量变化进行了调查和分析,对评价生态环境质量和合理利用水禽资源都有一定意义。一 ...
