Marine-viruses Journals

Viruses can be found in every environment on the Earth, but their importance is perhaps most evident in the oceans, where they are known to be the reservoir of most of the genetic diversity. Viruses kill approximately 20% of the oceanic microbial biomass daily, which has a significant impact on nutrient and energy cycles. This Review highlights areas in which marine virology is advancing quickly or seems to be poised for paradigm-shifting discoveries.Developing the necessary techniques to obtain accurate and reproducible estimates of the distribution and abundance of marine viruses has been a challenge for researchers. Sub-populations of both viruses and host cells can now be discriminated using flow cytometry. Viral abundance generally co-varies with prokaryotic abundance and productivity, but marked differences in this relationship have been reported in different marine environments.Quantifying the effects of viruses on marine prokaryotic and eukaryotic heterotrophic and autotrophic communities is also a challenging area, and remains one of the biggest obstacles to incorporating viral-mediated processes into global models of nutrient and energy cycling.Our knowledge of the diversity of viruses in marine environments has increased greatly with the development of metagenomic approaches.
