Method Abstract: "[Investigators] gathered data from 210 publications (and additional unpublished data) on viral ecology with the aim of exploring VPR [virus-to-prokaryote ratio]."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 right column bottom paragraph: "Following the development of microbial ecology in recent decades, new possible niches have been explored, such as so-called ‘extreme environments’. Although organisms from all three domains of life are found in extreme environments, bacteria and especially archaea are particularly abundant in the harshest environments. Viral numbers from undetectable levels up to 10^9 particles/ml have been documented (primary source Le Romancer et al., 2007) possibly mainly comprising archaeoviruses (primary source Prangishvili, Forterre & Garrett, 2006)."
