Seasonal dynamics of shallow-hyporheic-zone microbial community structure along a heavy-metal contamination gradient

Article Abstract:

The denaturing gradient gel electrophoresis (DGGE) analysis, real-time quantitative PCR and direct microscopic enumeration were used for verifying the hypothesis related to the influence of fluvially deposited heavy metals on hyporheic microbial community and the seasonal variation of the population abundance. The results suggest that during seasons, when the potential for growth is highest, then the abundance of susceptible populations respond to heavy metals.

Determining rates of change and evaluating group-level resiliency differences in hyporheic microbial communities in response to fluvial heavy-metal deposition

Article Abstract:

The rates of change in hyporheic microbial communities in response to heavy-metal contamination were determined and group-level differences in resiliency in response to heavy metals were assessed. Studies indicate that hyporheic microbial communities are sensitive and useful indicator of heavy-metal contamination in streams.
