Global biogeography of SAR11 marine bacteria
The ubiquitous SAR11 bacterial clade is the most abundant type of organism in the world’s oceans, but the reasons for its success are not fully elucidated. We analysed 128 surface marine metagenomes, including 37 new Antarctic metagenomes. The large size of the data set enabled internal transcribed...

The ubiquitous SAR11 bacterial clade is the most abundant type of organism in the world’s oceans, but the reasons for its success are not fully elucidated.
