岷江上游山地森林/干旱河谷交错带不同植被恢复模式对根际土壤微生物量碳氮及固氮菌群落结构的影响

Shuitu Baochi Xuebao, 2011
以岷江上游山地森林/干旱河谷交错带5种植被恢复模式的根际与非根际土壤为研究对象,对土壤微生物生物量碳、氮和土壤固氮菌群落结构的影响进行了初步研究.结果表明,5种不同植被根际与非根际土壤的微生物生物量存在显著差异且根际土壤含量大于非根际土壤,依次为:青冈次生林＞灌木林＞刺槐林＞人工幼林＞针阔混交林;DGGE图谱显示,5种植被根际与非根际土壤固氮类群有一条明显的共有条带,其中刺槐林和灌木林的固氮菌多样性最高;多样性指数、群落丰富度分析表明,灌木根际土壤固氮菌的群落种群结构最丰富,其次为刺槐;聚类分析结果显示,

高原鼠兔细菌群落的生物地理图谱

野生动物学报
高原鼠兔（Ochotona curzoniae）是青藏高原最具特色的小型哺乳动物之一，对青藏高原的生态系统有着重要作用。对高原鼠兔特定部位的细菌群落已有一些研究，但对多个部位细菌群落的生物地理图谱研究较少。为了探究高原鼠兔不同部位的细菌群落组成的差异，从青藏高原门源地区捕捉高原鼠兔，分别采集其脸部、毛发、肝脏、胃部、小肠和盲肠的样本，使用16S rRNA基因测序技术表征这些部位的细菌群落。结果表明：高原鼠兔不同部位的细菌群落组成差异较大，其脸部、毛发、肝脏、胃部和小肠中变形菌门 ...
