Global patterns of diversity and community structure in marine bacterioplankton Export

@article{citeulike:1102000, abstract = {Because of their small size, great abundance and easy dispersal, it is often assumed that marine planktonic microorganisms have a ubiquitous distribution that prevents any structured assembly into local communities.
