...Furthermore, cluster analysis showed that the actinobacterial communities in the QTP samples (including clod springs, hot springs and lakes) were grouped into one cluster, which has little similarity (Jaccard similarity 0.05) with that of marine sediments from Atlantic ocean and Tengchong hot springs (Figure 4)....

...The actinobacterial clones from the studied cold springs (this study) were closely related to those from the QTP hot springs and saline lakes (Figure 4), this indicated that the actinobacterial communities in the studied cold springs were more similar to that in other QTP samples (including hot springs and lakes) than to those in the samples from other locations....

...The observed geographic distribution of Actinobacteria in the QTP samples could be ascribed to the distinct conditions (e.g., dry climate, low pressure, high intensity Frontiers in Microbiology | www.frontiersin.org 7 November 2015 | Volume 6 | Article 1345 of UV radiation) of the cold springs, hot springs, and saline lakes on the QTP from other ecosystems (Jiang et al., 2010a, 2012a)....

...In addition, the Actinobacteria communities in the studied QTP cold spring sediments were different from those in marine sediments (Stach et al., 2003; Goodfellow et al., 2012) and freshwater ecosystems (Hahn et al., 2003; Warnecke et al., 2004; Ghai et al., 2012)....

...When entering into Holocene, although the large-scaled glaciation was finished, the whole QTP was still under gradual uplifting and its altitude rose to more than 4000 meters, of which the peculiar highness guaranteed that the whole plateau was still on the glacial margin ([26])....
