A marine virus is more likely to infect cooccurring organisms, those that live in the same region the virus lives in. [130] Therefore, biogeography is an important factor in a virion's ability to infect.
Viral shunting helps maintain diversity within the microbial ecosystem by preventing a single species of marine microbe from dominating the micro-environment. [245] The DOM recycled by the viral shunt pathway is comparable to the amount generated by the other main sources of marine DOM.
The name "marnaviridae" is based on its genome type (RNA virus - rnaviridae), together with the prefix "ma" being derived from the Latin word mare (sea).[10]The family was proposed following the discovery of an RNA virus (HaRNAV) that infects H. akashiwo off of the coast of British Columbia, which was the first report of a single-stranded RNA virus capable of causing cell lysis in phytoplankton.
Virosphere (virus diversity, virus world, global virosphere) was coined to refer to all those places in which viruses are found or which are affected by viruses. [1] [2] However, more recently virosphere has also been used to refer to the pool of viruses that occurs in all hosts and all environments, [3] as well as viruses associated with specific types of hosts (prokaryotic virosphere, [4 ...
Marine autotrophs are believed to stem from at least 8 ancient clades while terrestrial organisms mainly stem from one clade, Embyrophyta. [7] Marine environments may contain over 80% of the world's plant and animal species. [6] The diversity of coral reefs can be extraordinary with species diversity reaching 1000 species per meter squared.
[3] [4] Metagenomics can be used to study and analyze unculturable viruses and has been an important tool in understanding viral diversity and abundance and in the discovery of novel viruses. [1] [5] [6] For example, metagenomics methods have been used to describe viruses associated with cancerous tumors and in terrestrial ecosystems. [7]

The "Kill the Winner" hypothesis relates to Lotka-Volterra equations. Viral lysis, which disproportionately targets the "winners" of marine ecosystems.. The "Kill the Winner" hypothesis (KtW) is an ecological model of population growth involving prokaryotes, viruses and protozoans that links trophic interactions to biogeochemistry. [1]
