Title Marine viruses: small but important
Abstract Viruses are the most numerous and diverse biological entities in the oceans and they are important for biochemical cycling and structuring of microbial communities. Not only do viral infection and lysis influence the structure of prokaryote and eukaryote communities, it also control the partitioning of nutrient fluxes "up" the food chain via predation and "down" the food chain to the pool of dissolved organic material (DOM). Viruses also have the ability to influence the life history and evolution of the host community by acting as major conduits of genetic exchange. I will in this talk discuss viral diversity in the marine environment, and link viral activity to its function on both the prokaryotic and eukaryotic (phytoplankton) host communities. I will also discuss how abundance and activity of viruses and their heterotrophic prokaryotic hosts may be linked to trophic cascades initiated in the predator food chain in the marine microbial food web by combining results from mesoent with mathematical modelling.
