Snowpack insulates soils, creating unique conditions where wintertime soil microbial communities thrive. The subsequent turnover of soil microbes that occurs during snowmelt microbial communities provides a flush of nutrients just as plants are greening up. How may this pattern change under thinner snowpacks that melt earlier in the spring? We begin exploring these questions with a process-based land model that explicitly represents the activity and diversity of soil microbial communities. Our findings highlight key unknowns about the mechanisms responsible for seasonal changes in microbial community turnover and function.
