The self-fertilization rates were fluctuated among the hermaphrodites. These analyses demonstrated that the hermaphrodites accepted the spermatozoa from neighboring hermaphrodites and males. We propose the requirements for maintaining males, and for their successful reproduction in self-compatible hermaphrodite populations, to be: 1) high populationdensity, 2) low self-fertilization rates of hermaphrodites; 3) more spermatozoa and greater survival of males than those of hermaphrodites, 4) simultaneous discharge of gametes from hermaphrodites and males.","subitem_description_type":"Abstract"}]},"item_8_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"2016年度～2019年度科学研究費補助金(基盤研究(C))研究成果報告書","subitem_description_type":"Other"}]},"item_8_description_64":{"attribute_name":"科研費番号","attribute_value_mlt":[{"subitem_description":"16K07462","subitem_description_type":"Other"}]},"item_8_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"三重大学"}]},"item_8_text_31":{"attribute_name":"出版者（ヨミ）","attribute_value_mlt":[{"subitem_text_value":"ミエダイガク"}]},"item_8_text_65":{"attribute_name":"資源タイプ（三重大）","attribute_value_mlt":[{"subitem_text_value":"Kaken / 科研費報告書"}]},"item_8_version_type_15":{"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":"古丸, 明","creatorNameLang":"ja"},{"creatorName":"コマル, アキラ","creatorNameLang":"ja-Kana"},{"creatorName":"Komaru, Akira","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"遊佐, 陽一","creatorNameLang":"ja"},{"creatorName":"ユサ, ヨウイチ","creatorNameLang":"ja-Kana"},{"creatorName":"Yusa, Yoichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"河村, 功一","creatorNameLang":"ja"},{"creatorName":"カワムラ, コウイチ","creatorNameLang":"ja-Kana"},{"creatorName":"Kawamura, Kouichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-01-25"}],"displaytype":"detail","filename":"2021RP0107.pdf","filesize":[{"value":"79.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"2021RP0107","url":"https://mie-u.repo.nii.ac.jp/record/14573/files/2021RP0107.pdf"},"version_id":"2b8b344b-fd40-4ecb-8ffb-22828042b73d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"雄性発生","subitem_subject_scheme":"Other"},{"subitem_subject":"自家受精","subitem_subject_scheme":"Other"},{"subitem_subject":"卵胎生","subitem_subject_scheme":"Other"},{"subitem_subject":"タイワンシジミ","subitem_subject_scheme":"Other"},{"subitem_subject":"雌雄同体","subitem_subject_scheme":"Other"},{"subitem_subject":"雄性異体","subitem_subject_scheme":"Other"},{"subitem_subject":"androdioecy","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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"タイワンシジミの雄性発生とandrodioecyの起源,多様性獲得法の解明","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"タイワンシジミの雄性発生とandrodioecyの起源,多様性獲得法の解明","subitem_title_language":"ja"},{"subitem_title":"The origin of androdioecy and genetic diversity of androgenetic clam Corbicula lumina","subitem_title_language":"en"}]},"item_type_id":"8","owner":"15","path":["1692755237362"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2022-01-25"},"publish_date":"2022-01-25","publish_status":"0","recid":"14573","relation_version_is_last":true,"title":["タイワンシジミの雄性発生とandrodioecyの起源,多様性獲得法の解明"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2023-11-21T02:08:48.648443+00:00"}
