In order to clarify the environmental characteristics of Casuarina forests, we examined the canopy openness, litter depth, soil moisture, soil hardness, air temperature, and air humidity on Nishijima, which is widely occupied by the alien plants. We found that the canopy was opener, the litter was thicker, and the soil was drier in Casuarina forests than in native forests. These physical differences are likely to affect the faunal and floral assemblages. As experimental eradication is being conducted on the island, and the trend in the physical conditions should be monitored.","subitem_description_type":"Abstract"}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"首都大学東京小笠原研究委員会"}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00032332","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03868176","subitem_source_identifier_type":"ISSN"}]},"item_3_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"川上, 和人"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"阿部, 真"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"青山, 夕貴子"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-08-03"}],"displaytype":"detail","filename":"20001-36-001.pdf","filesize":[{"value":"3.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"20001-36-001.pdf","url":"https://tokyo-metro-u.repo.nii.ac.jp/record/2332/files/20001-36-001.pdf"},"version_id":"c002f02e-7b09-47b5-9b10-7f1fc12ce2ef"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"小笠原諸島西島におけるトクサバモクマオウ林の環境特性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"小笠原諸島西島におけるトクサバモクマオウ林の環境特性"}]},"item_type_id":"3","owner":"3","path":["485"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-09-28"},"publish_date":"2011-09-28","publish_status":"0","recid":"2332","relation_version_is_last":true,"title":["小笠原諸島西島におけるトクサバモクマオウ林の環境特性"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-19T18:38:52.028751+00:00"}
