Abstract: Viral Community Dynamics in Stream Bacterial Biofilms

Marine ecosystems have been a focal point for microbial ecology studies.  Over two decades of research in the global ocean has revealed important roles of viruses in marine ecosystems, from controlling host populations, to influencing how nutrients cycle within marine food webs, to influencing host evolution through gene transfer. In comparison, much less is known about the roles of viruses in freshwater systems. Streams are incredibly important to global ecology as a huge site of carbon cycling as well as a place where ecosystems are connected and integrated. And unlike the ocean, many freshwaters have complex connections with terrestrial watersheds, which can also influence virus dynamics in these systems.  Understanding the impacts of viruses in freshwater microbial communities is the next important challenge in this field of research.
