Why
Giant viruses influence microbial community dynamics, matter flow, and global biogeochemical cycles by causing host cell breakdown and modulating host physiology through auxiliary metabolic genes.
The Frontline Impact
How this affects you
Giant viruses play a critical role in polar ecosystems by recycling nutrients and influencing energy output, which is further complicated by virophages that regulate their activity, ensuring the stability and unique diversity of these extreme environments.
