title: Response of soil bacterial community structure to successive perturbations of different types and intensities.
abstract: In soil, genetic structure modifications of indigenous bacterial community consecutively to a severe stress (mercury contamination) were delayed when the community was pre-exposed to various minor perturbations (heat, copper and atrazine). Such minor perturbations induced transitory community structure modifications leading to an increase of community stability towards a severe mercury stress. These results illustrated well the short-term pre-adaptation process for bacterial community hypothesizing that community submitted to perturbations become more resistant to withstand another stress.
