The reproductive seasons of three native mytilid species, Hormomya mutabilis, Septifer bilocularis, and S. virgatus, were studied in Uranouchi Inlet, Kochi, Japan. Seasonal fluctuations in the somatic index (SI), condition index (CI), and standard wet weight (SWW) revealed that these mussels spawned from summer to early autumn, which coincided with the spawning season of the nonindigenous mussel Perna viridis. It is suggested that H. mutabilis, S. bilocularis, and P. viridis compete in both adult and recruit phases.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"Yamada, Chiharu"}]},{"nameIdentifiers":[{}],"names":[{"name":"Kakio, Taro"}]},{"nameIdentifiers":[{}],"names":[{"name":"Kurita, Hiroshige"}]},{"nameIdentifiers":[{}],"names":[{"name":"Itani, Gyo"}]}]},"item_4_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"高知大学大学院総合人間自然科学研究科黒潮圏総合科学専攻","subitem_publisher_language":"ja"}]},"item_4_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1882823X","subitem_source_identifier_type":"ISSN"}]},"item_4_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12321175","subitem_source_identifier_type":"NCID"}]},"item_4_version_type_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"山田, ちはる"}],"nameIdentifiers":[{"nameIdentifier":"24474"}]},{"creatorNames":[{"creatorName":"垣尾, 太郎"}],"nameIdentifiers":[{"nameIdentifier":"24475"}]},{"creatorNames":[{"creatorName":"栗田, 浩成"}],"nameIdentifiers":[{"nameIdentifier":"24476"}]},{"creatorNames":[{"creatorName":"伊谷, 行"}],"nameIdentifiers":[{"nameIdentifier":"24477"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-04-23"}],"displaytype":"detail","filename":"138yamada.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"138yamada.pdf","url":"https://kochi.repo.nii.ac.jp/record/6471/files/138yamada.pdf"},"version_id":"d26a14d4-8f77-409e-a2c3-3bb9cde86d8d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ヒバリガイモドキ","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"クジャクガイ","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"ムラサキインコ","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"ミドリイガイ","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"繁殖期","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"軟体部重量比","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"肥満度","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"Hormomya mutabilis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Septifer bilocularis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Septifer virgatus","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Perna viridis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"reproductive seasons","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"somatic index","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"condition index","subitem_subject_language":"en","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":"高知県浦ノ内湾におけるイガイ科二枚貝類３種の繁殖期","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"高知県浦ノ内湾におけるイガイ科二枚貝類３種の繁殖期","subitem_title_language":"ja"},{"subitem_title":"A comparison of the reproductive seasons of three mytilid species in Uranouchi Inlet, Kochi, Japan","subitem_title_language":"en"}]},"item_type_id":"4","owner":"3","path":["583"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2010-04-15"},"publish_date":"2010-04-15","publish_status":"0","recid":"6471","relation_version_is_last":true,"title":["高知県浦ノ内湾におけるイガイ科二枚貝類３種の繁殖期"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-08-22T00:33:12.853161+00:00"}
