| Outline of Final Research Achievements |
We investigated the actual conditions of the metabolism of the greenhouse gas methane in the northeastern Siberian permafrost wetland and the microbial communities involved in it and the response to environmental changes. While the methane oxidation potential, which is the key to methane emission, is found to be higher than that of the other arctic wetland soils, it has been shown that its function as a deterrent to methane emission is weak. Also, regarding the composition of the soil microbial community, the difference from the other arctic soils was clarified, and the uniqueness of this area was clarified.

| Academic Significance and Societal Importance of the Research Achievements |
本研究では、地球環境変動の影響が最も懸念される環北極域のなかでも調査が進んでいない北東シベリアを対象に、ガス代謝と微生物叢の解析を同時に行い、永久凍土湿地土壌の物質循環とそれに関わる微生物群集を明らかにした。メタン酸化に対する温度条件の影響やメタン酸化に関わる微生物叢の知見は、温暖化に対する永久凍土帯のガス代謝の応答と将来予測に資する生物的パラメータを提供するものと期待される。
