In this work, we present in situ measurements of CO_2-C emissions and assess their relation with soil temperature, using dynamic chambers. We found an exponential relation between CO_2 emissions and soil temperature, with the value of Q_<10> being close to 2.1. Mean emission rates were as low as 0.026 and 0.072 g of CO_2-C m^<-2> h^<-1> for bare soil and soil covered with moss, respectively, and as high as 0.162 g of CO2-C m^<-2> h^<-1> for soil covered with grass, Deschampsia antarctica Desv. (Poaceae). A spatial variability analysis conducted using a 60-point grid, for an area with mosses (Sannionia uncianata) and D. antarctica, yielded a spherical semivariogram model for CO2-C emissions with a range of 1 m. The results suggest that soil temperature is a controlling factor on temporal variations in soil CO2-C emissions, although spatial variations appear to be more strongly related to the distribution of vegetation types.","subitem_description_type":"Abstract"}]},"item_10001_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"南極地域において野外環境下で土壌呼吸を測定し、土壌温度との関係を調査した。土壌温度と土壌呼吸の間には指数関数的な関係が認められ、Q10は2.1だった。土壌呼吸の平均値は、植生の有無やタイプによって異なり、裸地で0.026、コケで0.072そして維管束植物(Deschampsia antarctica)で0.162 g of CO2-C m-2 h-1だった。さらにコケと維管束植物の生育するエリアの土壌呼吸の空間的ばらつきについても解析した。以上の結果から、土壌呼吸の時間変動には土壌温度が影響しているのに対して、空間的ばらつきには植生タイプがより強く関係していることが示唆された。","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":"110007721893","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.2010.07.001"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.1016/j.polar.2010.07.001","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 only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Newton, La Scala Junior"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Eduardo, de Sa Mendonca"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Juliana, Vanir de Souza"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Alan, Rodrigo Panosso"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Felipe, N.B.
