Method Abstract: "[Investigators] gathered data from 210 publications (and additional unpublished data) on viral ecology with the aim of exploring VPR [virus-to-prokaryote ratio]."
Comments P.1086 left column top paragraph: "Aquatic marine and freshwater ecosystems are characterized by VPR values ranging between 0.008 (Proctor & Fuhrman, 1990) and 2150 (Clasen et al., 2008) (Table 1), giving an overall average of 21.9. The apparent trend, based on average viral and prokaryotic abundances (Table 2), suggests higher mean VPR values in the open ocean and offshore, as well as in deep-sea waters, when compared to coastal and estuarine waters, as reported in previous reviews. This might appear surprising as higher viral numbers might be expected to give rise to higher VPR values, but is presumably due to differences in prokaryotic abundance."
