If you were to collect all the organisms from the ocean surface down to 200 meters, you'd find that SAR11 bacteria, though invisible to the naked eye, would make up a fifth of the total biomass. These ...

Computer models reveal how human-driven climate change will dramatically overhaul critical nutrient cycles in the ocean. Researchers report evidence that marine nutrient cycles -- essential for ...

An example of a transport protein in a SAR11 bacterium and its distribution in samples of ocean from across the world. Because of their abundance, these transport proteins are widely distributed ...
