- Description: An Inner Mongolia precipitation experiment found plant and AMF diversity moving differently while reduced rainfall pushed both communities toward similar patterns of spatial compositional variability.

Evidence

Peer-reviewed

Geography

Inner Mongolia, China

System

Temperate grassland

## WHAT THE EVIDENCE SAYS

A field experiment compared ambient precipitation with 50% reductions and increases. Plant and arbuscular-mycorrhizal-fungal diversity responded differently, but their spatial compositional variability converged under reduced precipitation; AMF variation was driven primarily by abiotic soil filtering.

## WHY IT MATTERS / OUR READ

Aboveground and belowground diversity do not have to move together even when drought reorganizes both communities. That complicates attempts to infer soil symbiont response from vegetation monitoring alone.

## CAVEATS / UNCERTAINTY

The experiment represents one temperate-grassland system and a defined precipitation manipulation. Community-level sequencing and spatial-variability metrics do not directly establish changes in ecosystem function.
