抄録/ポイント： 地球温暖化は永久凍土を伴う高緯度ツンドラの下層に影響を及ぼすことはよく知られている。これは,世界のSOC貯蔵の約50%を占めるこの地域で以前に貯蔵された土壌有機炭素(SOC)の分解が気候温暖化を加速する正のフィードバックを引き起こすという厳しい懸念をもたらす。著者らは以前,短期温暖化(1.5年)が土壌微生物群集の組成に影響することなくツンドラ土壌炭素の急速な微生物媒介分解を刺激することを示した(土壌試料の3g当たり16S rRNA遺伝子アンプリコンの深さに基づく)。同じ場所での長期(5年)の実験的冬季温暖化は微生物群集を変化させることを示した(p<0.040)。解凍深さは群落集合と相互作用ネットワークと最も強く相関し,温暖化促進ツンドラ解凍が基本的に微生物群集を再構成することを意味した。炭素分解とメタン生成遺伝子の両方が温暖化の下で相対存在量で増加し,それらの機能構造は生態系呼吸またはCH4フラックスと強く相関した(R2>0.725,p<0.001)。これらの結果は,炭素循環に関連する微生物応答が,SOC損失が微生物群集組成の変化により副生されないため,ツンドラ地域におけるSOC分解を加速する正フィードバックをもたらすことを示した。Copyright 2020 The Author(s) All rights reserved.
