Why
Giant viruses act as biogeochemical engineers by causing host cell breakdown, releasing organic matter, and modulating host physiology through auxiliary metabolic genes.
The Frontline Impact
How this affects you
The discovery of these giant viruses and their role in polar ecosystems highlights their profound influence on microbial community dynamics and global biogeochemical cycles. Their impact on maintaining the stability of these extreme environments, including the Last Ice Area, is critical, especially as rapid warming threatens to break down physical barriers and cause ecological restructuring.
