Abstract
Across biomes, soil biodiversity promotes ecosystem functions. However, whether this relationship will be maintained under climate change is uncertain. Here, using two long-term warming experiments, we investigated how warming affects the relationship between ecosystem functions and microbial diversity across seasons, soil horizons, and warming duration. The soils in these warming experiments were heated +5 °C above ambient for 13 or 28 years. We measured seven different ecosystem functions representative of soil carbon cycling, soil nitrogen cycling, or nutrient pools. We also surveyed bacterial and fungal community diversity. We found that the relationship between ecosystem function and bacterial diversity and the relationship between ecosystem function and fungal diversity was unaffected by warming or warming duration. Ecosystem function, however, was significantly affected by season, with autumn samples having higher function than summer samples. Our findings further emphasize that season is a consistent driver of ecosystem function and that this is maintained even under simulated climate change.
