We found that algal andcyanobacterial communities differed between the glaciers and that the amount of biomass was higher on the colder glacier (Qaanaaq Glacier). The community on the Qaanaaq Glacier was composed mainly of green algae, whereas that on the Russel Glacier was dominated by cyanobacteria. Despite the shorter melting period (due to colder air temperature) for the QaanaaqGlacier, the biovolume of algae and cyanobacteria was 2.35 times higher than that on the Russel Glacier at a similar altitude, suggesting greater primary production on the Qaanaaq Glacier. We discuss the possible effects of temperature, nutrient concentrations, and cryoconite holes (melt-holes in the glacier) on the community structure and productivity of algae and cyanobacteria on each glacier, and consider the influence of the identified differences in algal and cyanobacterial communities on the amount of surface melt.","subitem_description_type":"Abstract"}]},"item_10001_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"西グリーンランドの二つの氷河（Qaanaaq氷河、Russel氷河）において、衛星画像の比較から北東部に位置するQaanaaq氷河消耗域は黒く汚れた表面であるのに対して、中西部のRussel氷河では汚れが少ない事が明らかとなっていた。本研究では、これらの原因の１つに雪氷微生物が関与していると推測し、両氷河での藻類、シアノバクテリアの群集に関する分析、比較を行った。藻類、シアノバクテリアの群集は両氷河で異なっており、これらの総生物量は寒冷であるQaanaaq氷河で高かった。Qaanaaq氷河は主に緑藻類が多いのに対して、Russel氷河ではシアノバクテリアが優占していた。寒冷で融解期間が短いにも関わらず、Qaanaaq氷河での生物量はRussel氷河の同高度帯よりも2.35倍大きく、この事はQaanaaq氷河においてより多くの一次生産がある事を示した。気温、栄養塩濃度、クリオコイトホールの構造、緑藻、シアノバクテリアの生産性の影響を考慮して、これらの違いが何故起きたのか考察をした。","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":"110007583482","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.2010.03.002"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.1016/j.polar.2010.03.002","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":"Uetake, Jun"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Naganuma, Takeshi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hebsgaard, Martin Bay"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kanda, Hiroshi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kohshima, Shiro"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Uetake, Jun","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Naganuma, Takeshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hebsgaard, Martin Bay","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kanda, Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kohshima, Shiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Greenland","subitem_subject_scheme":"Other"},{"subitem_subject":"Glacier","subitem_subject_scheme":"Other"},{"subitem_subject":"Green algae","subitem_subject_scheme":"Other"},{"subitem_subject":"Cyanobacteria","subitem_subject_scheme":"Other"},{"subitem_subject":"Cryoconite","subitem_subject_scheme":"Other"},{"subitem_subject":"Greenland","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Glacier","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Green algae","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Cyanobacteria","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Cryoconite","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Communities of algae and cyanobacteria on glaciers in west Greenland","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Communities of algae and cyanobacteria on glaciers in west Greenland"},{"subitem_title":"Communities of algae and cyanobacteria on glaciers in west Greenland","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"17","path":["1354"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-10-16"},"publish_date":"2014-10-16","publish_status":"0","recid":"10152","relation_version_is_last":true,"title":["Communities of algae and cyanobacteria on glaciers in west Greenland"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-07-25T16:20:34.619745+00:00"}
