Implication

Observational analysis shows substrate availability drives soil carbon dynamics in subalpine soils, suggesting shifts towards carbon sources with climate change.

Key Points

Total organic carbon losses reached 11.8% in forest soils after litter addition, highlighting the impact of substrate on decomposition.
Soil carbon dynamics were assessed through incubations at multiple temperatures over 360 days, emphasizing litter's role.
Increased labile carbon from litter inputs may convert subalpine soils from carbon sinks to sources under warming conditions.
The findings underscore the importance of vegetation cover and substrate quality in determining soil organic matter decomposition.
