In a High-Arctic oasis showing atypical \"directional primary succession\", we quantified the microhabitat characteristics associated with colonization by pioneer vascular plants of a bare moraine. The study moraine, formed during the Little Ice Age, is located within the proglacial area at the southern front of Arklio Glacier, Ellesmere Island, Canada. We established two line-transects on this moraine to quantify microhabitats for vascular species. Microsites favorable for plants were concave depressions, probably increasing the likelihood of colonization. At microsites distant from stable boulders, which probably protect seeds/seedlings from wind desiccation, plant colonization was less likely. Furthermore, favorable microhabitat properties differed depending on topographical location within the moraine, suggesting that, even within a single moraine, microhabitats favorable for plant colonization are heterogeneously-distributed. This moraine was characterized by two major pioneer species, Epilobium latifolium and Salix arctica. Their species-specific microhabitat requirements highlight the importance of biotic factors in colonization processes. Favorable sites for plants are generally distributed at random in harsh environments. However, we showed that initial plant colonization is a deterministic process rather than random, indicating the possibility of non-stochastic processes even during the early phase of ecosystem development in High-Arctic ecosystems.","subitem_description_type":"Abstract"}]},"item_10001_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"　生態系の一次遷移において、植物の初期定着はその後の生態系発達を決定づける重要な要因である。そこで本研究では、高緯度北極圏の極地オアシスにおいて、小氷期に形成されたモレーン上のパイオニア種（維管束植物種）の分布と定着場所の環境要因を解析した。その結果、植物定着を促す場所は、礫が近くにある凹地上のマイクロサイトであった。このような場所は、植物が乾燥により枯死することを防ぎつつ、比較的良好な水分供給を可能にするためであると推察される。このような環境－植物の対応は、遷移初期過程では植物の分布はランダムであるとの一般的な仮定とは異なり、植物の侵入・定着は非確率論的なプロセスが働いているこ可能性を示唆している。 ","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":"110009647319","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.2013.09.002"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.1016/j.polar.2013.09.002","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":"Mori, Akira S."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Uchida, Masaki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kanda, Hiroshi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Mori, Akira S.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Uchida, Masaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kanda, Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Community development","subitem_subject_scheme":"Other"},{"subitem_subject":"Deglaciated moraine","subitem_subject_scheme":"Other"},{"subitem_subject":"Glacier foreland","subitem_subject_scheme":"Other"},{"subitem_subject":"Microhabitat characteristics","subitem_subject_scheme":"Other"},{"subitem_subject":"Primary succession","subitem_subject_scheme":"Other"},{"subitem_subject":"Community development","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Deglaciated moraine","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Glacier foreland","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Microhabitat characteristics","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Primary succession","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":"Non-stochastic colonization by pioneer plants after deglaciation in a polar oasis of the Canadian High Arctic","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Non-stochastic colonization by pioneer plants after deglaciation in a polar oasis of the Canadian High Arctic"},{"subitem_title":"Non-stochastic colonization by pioneer plants after deglaciation in a polar oasis of the Canadian High Arctic","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"27","path":["1346"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-10-15"},"publish_date":"2014-10-15","publish_status":"0","recid":"10060","relation_version_is_last":true,"title":["Non-stochastic colonization by pioneer plants after deglaciation in a polar oasis of the Canadian High Arctic"],"weko_creator_id":"27","weko_shared_id":27},"updated":"2023-07-25T16:21:54.277769+00:00"}
