Hypolithic Microbial Community of Quartz Pavement in the High-Altitude Tundra of Central Tibet
The hypolithic microbial community associated with quartz pavement at a high-altitude tundra location in central Tibet is described. A small-scale ecological survey indicated that 36% of quartz rocks were colonized. Community profiling using terminal restriction fragment length polymorphism revealed...
