In this paper, we examine CO2 exchange rates (e.g., NPP and Re) in juniper haircap moss (Polytrichum juniperinum) and microbial respiration in no-vegetation conditions using an automated chamber system in a five-year burned black spruce forest in interior Alaska during the fall season of 2009. Mean ± standard deviation microbial respiration and NEP (net ecosystem productivity) of juniper haircap moss were 0.27 ± 0.13 and 0.28 ± 0.38 gCO2/m2/hr, respectively. CO2 exchange rates and microbial respiration showed temporal variations following fluctuation in air temperature during the fall season, suggesting the temperature sensitivity of juniper haircap moss and soil microbes after fire. During the 45-day fall period, mean NEP of P. juniperinum moss was 0.49 ± 0.28 MgC/ha following the five-year-old forest fire. On the other hand, simulated microbial respiration normalized to a 10°C temperature might be stimulated by as much as 0.40 ± 0.23 MgC/ha. These findings demonstrate that the fire-pioneer species juniper haircap moss is a net C sink in the burned black spruce forest of interior Alaska.","subitem_description_type":"Abstract"}]},"item_10001_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"　北方黒トウヒ林は、森林火災の影響を非常に受けてやすいし、 火災後土壌温度や基質の変化が大気中の炭素の正味のシンクからソースのような生態系の大きな領域をシフトする可能性がある。本論文では、二酸化炭素の交換速度（例えば、純一次生産量と生態系呼吸）を調べるために、2009年度の秋、アラスカ内陸部の焼けた黒トウヒ林に生育しているジュニパーヘアキャップ苔（Polytrichum juniperinum）や無植生地で自動化チャンバーシステムを用いた。平均微生物呼吸および、ジュニパーヘアキャップ苔の純生態系生産量は、それぞれ0.27 ± 0.13および0.28 ± 0.38 gCO2/m2/hrであった。二酸化炭素の交換速度および、微生物呼吸は、火災後ジュニパーヘアキャップ苔と土壌微生物の温度依存性を示唆し、秋の気温の変動とともに経時変化を示した。森林火災から5年目、2009年度の秋の期間（45日間）におけるP. juniperinum苔の純生態系生産量が、 0.49 ± 0.28 MgC/haであった。一方、10℃の温度に正規化された微生物の呼吸は限り0.40 ± 0.23 MgC/haになった。これらの知見は、火災先駆種であるヘアキャップ苔は、焼けたアラスカ内陸部の黒トウヒ林におけるやや正味の炭素シンクであることを示している。","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立極地研究所"}]},"item_10001_relation_12":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"110009794531","subitem_relation_type_select":"NAID"}}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1016/j.polar.2014.01.003"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.1016/j.polar.2014.01.003","subitem_relation_type_select":"DOI"}}]},"item_10001_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12240481","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18739652","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata
