Shrub range expansion alters diversity and distribution of soil fungal communities across an alpine elevation gradient.
Global climate and land use change are altering plant and soil microbial communities worldwide, particularly in arctic and alpine biomes where warming is accelerated. The widespread expansion of woody shrubs into historically herbaceous alpine plant zones is likely to interact with climate to affect...

The widespread expansion of woody shrubs into historically herbaceous alpine plant zones is likely to interact with climate to affect soil microbial community structure and function; however, our understanding of alpine soil ecology remains limited.

We found that soil fungal diversity declines and community composition changes with increasing elevation.
