Outline of Final Research Achievements |
We aimed to clarify the maintenance mechanism of microbial ecosystem of forest soil with short-term high-temperature and long-term low-temperature disturbances with resistance, resilience and function redundancy as stability index. <Short-term/high-temperature disturbance> In the pyrotechnic field, soil microbial community structure analysis was performed before the burning and one day to three years after the burning. Disappearance of diversity that single species prefers immediately after burning is observed, and in the third year it is getting close to composition before burning. The resilience was shown to be short-term. <Long-term/low temperature disturbance> In the warming field with the ground temperature of +5°C, no significant change in microbial community composition was observed compared with the untreated field despite soil warming for 10 years. It showed the robustness of the soil microbial community.
