This study shows that the composition of planktonic bacteria can show provincialism at small spatial scales, which is likely to be caused by -environmental conditions as well as historical events.

- This study investigates the importance of local vs. spatial factors on bacterial community composition of 35 rock pools at the Baltic Sea coast.
