The rate of recruitment was low in the population where there was a high adult density, i.e. in excess of 10 plants/m2 but it was conspicuously high in the population where there was a low adult density, i.e. less than 5 plants/m2. The newly germinated plants in the low adult density population grew into the succeeding generation of the population. It took five to six years before adult density again decreased to a level below 5 plants/m2. The regeneration cycle of the population, therefore, found to be five to six years.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"牡鹿半島泊浜沿岸のアラメ群落内の成体密度が異なる2ヵ所に永久方形枠を設置して各年級群密度の変化を1987年11月から1989年6月まで約3年間観察し,群落の更新過程を考察した,成体密度が10個体/m2以上では後継群はあまり形成されないが,5個体未満では顕著に形成された.成体密度が5個体以下に低下し,新たに後継群が形成するまでには5~6年を要することがわかった.","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東北海区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Tohoku National Fisheries Researh Institute","subitem_publisher_language":"en"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"tnf_k_52_9","subitem_relation_type_select":"Local"}}]},"item_10002_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"ja","subitem_relation_name_text":"日本農学文献記事索引(agriknowledge)"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://agriknowledge.affrc.go.jp/RN/2010460870","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00167637","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0049-402X","subitem_source_identifier_type":"PISSN"}]},"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":"谷口, 和也","creatorNameLang":"ja"}],"familyNames":[{"familyName":"谷口","familyNameLang":"ja"}],"givenNames":[{"givenName":"和也","givenNameLang":"ja"}]}]},"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":"牡鹿半島沿岸におけるアラメ群落の更新過程","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"牡鹿半島沿岸におけるアラメ群落の更新過程","subitem_title_language":"ja"}]},"item_type_id":"10002","owner":"10","path":["1716950799012"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-06-10"},"publish_date":"2024-06-10","publish_status":"0","recid":"2007366","relation_version_is_last":true,"title":["牡鹿半島沿岸におけるアラメ群落の更新過程"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-02-04T00:33:10.026330+00:00"}
