dc.description.abstractBacterial abundances in ice cores vary in response to climatic conditions. This paper presents annual bacterial abundances measured in ice deposited over the past 70 years and trapped within a core retrieved from Mount Geladaindong, on the central Tibetan Plateau. The bacterial abundance was lowest in 1938 and highest in 1997. Analyses of correlations between bacterial abundance and delta(18)O and Ca(2+) concentrations indicate that bacterial abundance correlates positively with both temperature and amount of dust transported onto the glacier. These correlations imply that both higher temperatures and more frequent dust deposition influence bacterial abundance in the Geladaindong ice core. Bacterial genetic diversity also changes seasonally, and the diversity during the monsoon season appears much higher than during the nonmonsoon season. Bacterial sequences representing the monsoon season were related to bacteria originating from various environmental conditions while these, representing the nonmonsoon season, were typically related to microorganisms coming from cold environments and soils.zh_CN
