These two species are introduced mangrove species in Okinawa Island. Northern limit distribution of A. marina is in Miyako Island. While, that of A. alba is in the Philippines. The distribution of A. marina is on the wetland all over the inland sea and dense distribution on the side of the inland sea of Yagaji Island. While, the distribution of A. alba is just limited on the wetland of Gabu area of Yagaji Island facing the inland sea. These two species belong to the same genus, however, their distribution is significantly different in the inland sea. It is supposed that this difference caused their adaptation to the inland sea wetland environment. Reproduction season, fruit production, fruit size, and growth of sapling are compared for consideration of their adaptation to the inland sea wetland. Reproduction season of A. alba came earlier than two weeks to one month of that of A. marina and the formation of bud and fruit are less than half of A. marina. As for fruit production, A. marina is significantly higher than that of A. alba. The fruit size of A. alba is 2.2 times larger than that of A. marina. The growth rate of A. alba is more than 2 times higher than that of A. marina, and after three years from seedling rooting, flower bud formation occurred on 3 trees out of 10 saplings of the species, however resulted in three matured fruits adhesion to a branch of one tree as an influence of the Typhoon No. 25 that brought strong gust of wind. On the other hands, no flower bud formation observed on A. marina. An adaptive attribute of A. marina of the research was fruit production, which supposed to be primary factor to explain current distribution of A. marina in the inland sea.","subitem_description_type":"Other"}]},"item_8_description_9":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_8_publisher_10":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"名桜大学"}]},"item_8_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"名桜大学"}]},"item_8_source_id_6":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1882-4412","subitem_source_identifier_type":"ISSN"}]},"item_8_text_11":{"attribute_name":"公開者別名","attribute_value_mlt":[{"subitem_text_value":"Meio University"}]},"item_8_text_15":{"attribute_name":"タイプ","attribute_value_mlt":[{"subitem_text_value":"紀要論文"}]},"item_8_text_16":{"attribute_name":"NIIタイプ","attribute_value_mlt":[{"subitem_text_value":"Departmental Bulletin Paper"}]},"item_8_text_17":{"attribute_name":"DCMI","attribute_value_mlt":[{"subitem_text_value":"text"}]},"item_8_text_18":{"attribute_name":"収録種別","attribute_value_mlt":[{"subitem_text_value":"紀要論文"}]},"item_8_text_19":{"attribute_name":"収録種別","attribute_value_mlt":[{"subitem_text_value":"02"}]},"item_8_text_20":{"attribute_name":"収録雑誌名","attribute_value_mlt":[{"subitem_text_value":"名桜大学紀要 = THE MEIO UNIVERSITY BULLETIN"}]},"item_8_text_21":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_text_value":"AN10512334"}]},"item_8_text_4":{"attribute_name":"別言語の著者","attribute_value_mlt":[{"subitem_text_value":"Arakaki, Yuji"}]},"item_8_text_5":{"attribute_name":"作成日","attribute_value_mlt":[{"subitem_text_value":"2019-03"}]},"item_8_version_type_24":{"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":"新垣, 裕治"},{"creatorName":"あらかき, ゆうじ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3182","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-03"}],"displaytype":"detail","filename":"No24p49.pdf","filesize":[{"value":"2.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"No24p49.pdf","url":"https://meio-u.repo.nii.ac.jp/record/1439/files/No24p49.pdf"},"version_id":"fc7fb292-ac8f-41a2-81e3-9e1dce43cbf1"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ヒルギダマシ","subitem_subject_scheme":"Other"},{"subitem_subject":"ウラジロヒルギダマシ","subitem_subject_scheme":"Other"},{"subitem_subject":"繁殖時期","subitem_subject_scheme":"Other"},{"subitem_subject":"果実生産量","subitem_subject_scheme":"Other"},{"subitem_subject":"幼樹成長","subitem_subject_scheme":"Other"},{"subitem_subject":"A. marina","subitem_subject_scheme":"Other"},{"subitem_subject":"A. alba","subitem_subject_scheme":"Other"},{"subitem_subject":"reproduction season","subitem_subject_scheme":"Other"},{"subitem_subject":"fruit production","subitem_subject_scheme":"Other"},{"subitem_subject":"growth of sapling","subitem_subject_scheme":"Other"}]},"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":"羽地内海沿岸干潟に分布する移入種マングローブのヒルギダマシAvicennia marinaとウラジロヒルギダマシA.albaの環境適応の比較 : 繁殖時期，果実生産量，果実サイズ及び幼樹の成長について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"羽地内海沿岸干潟に分布する移入種マングローブのヒルギダマシAvicennia marinaとウラジロヒルギダマシA.albaの環境適応の比較 : 繁殖時期，果実生産量，果実サイズ及び幼樹の成長について"}]},"item_type_id":"8","owner":"1","path":["76"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-07-17"},"publish_date":"2019-07-17","publish_status":"0","recid":"1439","relation_version_is_last":true,"title":["羽地内海沿岸干潟に分布する移入種マングローブのヒルギダマシAvicennia marinaとウラジロヒルギダマシA.albaの環境適応の比較 : 繁殖時期，果実生産量，果実サイズ及び幼樹の成長について"],"weko_creator_id":"1","weko_shared_id":1},"updated":"2023-05-15T12:30:09.147729+00:00"}
