There is a significant association between viral community composition and carbon export efficiency on a global scale, with viruses predicted to infect ecologically important hosts playing a crucial role in this process. These findings suggest that viruses likely act in the carbon pump process at a large scale in a manner dependent on their hosts and ecosystem dynamics.
The biological carbon pump, in which carbon fixed by photosynthesis is exported to the deep ocean through sinking, is a major process in Earth's carbon cycle. The proportion of primary production that is exported is termed the carbon export efficiency (CEE). Based on in-lab or regional scale observations, viruses were previously suggested to affect the CEE (i.e., viral shunt'' and shuttle''). In this study, we tested associations between viral community composition and CEE measured at a global scale. A regression model based on relative abundance of viral marker genes explained 67% of the variation in CEE. Viruses with high importance in the model were predicted to infect ecologically important hosts. These results are consistent with the view that the viral shunt and shuttle functions at a large scale and further imply that viruses likely act in this process in a way dependent on their hosts and ecosystem dynamics.
