Abstract

The diversity and structure of bacterial and actinobacteral diversity and communities were determined in a metallophytic grassland soil from an upland site in northern England. The community profiles were subjected to multivariate analyses using correspondence and cluster analyses. The total bacterial community diversities and structures were not significantly affected by Pb and Zn concentration in the soil. However, the community structure did show changes between winter and summer samples. Raup and Crick analysis indicated that deterministic selection lead to winter profiles exhibiting significant similarity. The actinobacterial community was also unaffected by Pb and Zn concentration. However, seasonal changes were apparent as diversity were significantly lower in winter compared to summer profiles. Moreover, the community structure showed evidence of changes of structure based on the seasonal samples with winter samples showing significant similarity to each other.
