Evidence

Peer-reviewed

Geography

Qinghai–Tibet Plateau

System

Alpine permafrost soils

## WHAT THE EVIDENCE SAYS

Metagenomic analysis of 150 samples from six 15-metre permafrost cores found microbial and functional diversity declining with depth, while degradation reduced diversity mainly in the active layer. Viral groups and virulence-associated genes were enriched in the frozen fringe, and carbon- and nitrogen-cycling gene patterns shifted with hydrothermal conditions.

## WHY IT MATTERS / OUR READ

Permafrost change is vertically structured. Surface sampling alone may miss microbial and biogeochemical changes concentrated at thaw boundaries that could affect nutrient loss and downstream ecosystem function.

## CAVEATS / UNCERTAINTY

Gene presence indicates functional or virulence potential, not demonstrated pathogen emergence or disease risk. The study should not be read as evidence of an imminent public-health threat.
