Reconstructing the invasion history of Heracleum persicum (Apiaceae) into Europe.

abstract：:Determining the structure of bacterial communities and their response to stimuli is key to understanding community function and the interactions that occur between micro-organisms and the environment. However, bacterial communities often comprise complex assemblages of large numbers of different bacterial populations....
