河流和水库细菌群落是河流生物群落和生态系统结构的最基本部分,在河流生物过程中起着重要作用。然而,尚不清楚高度调节的大坝水库如何影响土壤和沉积物细菌群落。在三个峡谷储层(TGR)的过渡部分中,使用Illumina Miseq测序研究了细菌群落的时间分布模式。总共有106,682个特征属于细菌王国,包括95个门,228个类别,514个订单,871个家庭,1959年属和3,053种。具有水位调节,香农多样性指数和观察到的物种差异很大,辛普森偶数没有显着差异。在高水位时期(10月)和低水位时期(6月),proteeobacteria,Acidobacteri和Chloroflexi都是最丰富的门。虽然基于PCA图和Circos图,微生物群落结构已发生了很大变化。lefse方法用于识别分类的细菌类群,低水位和高水位时期之间存在明显的丰度差异。KOS(KEGG矫正)途径富集分析,以研究组中的功能和相关代谢途径。在某种程度上可以推断,水位法规通过影响微生物群落的代谢影响社区的成长。
This article discusses the grand strategy imperatives of 37 foreign policy experts in Washington, DC. in response to President Donald Trump's nationalist challenge to the post-WWII international order concept. Using an abductive reconstructivist methodology to analyze in-depth interviews, five grand strategy imperatives or rules for action shared by all actors were identified: safeguarding US global leadership, maintaining alliances, securing US prosperity, value orientation, and the belief in a mission. Based on the interpretation of these rules for action, four types of foreign policy experts were distinguished: nationalists, realists, pragmatic liberals, and liberals. The latter three expert types, also labelled globalists, were united in their opposition to the nationalists' demolition of the international order but divided along partisan and ideological lines about the meaning and implementation of the rules for action. Realists, pragmatic liberals, and liberals were also unsure of how to explain and respond to Trump's nationalism beyond a defensive or wishful hope to save the vestiges of an US-centric international order. The findings demonstrate the value of in-depth qualitative interviews for explaining elite beliefs, illustrating the rich insights for policy analysis that can be gained through this methodology.
