The growth of juvenile horseshoe crabs was estimated using carapace width (CW) frequency analysis. The CW frequency was separated into four instars with 17.00-62.00 mm of CW range, resulting that each area of unimodal distribution showed the CW ranges from 5 to 8 instars. The mean CW of juvenile horseshoe crabs increased 1.35, 1.33 and 1.31 times with the molting process, and these values were higher than the growth rate under the rearing condition for the previous study. Dividing the captured individuals into age groups according to the CW ranges obtained from this study, it would become possible to monitor the increase and decrease of the threatened wild population. The endangered horseshoe crab can be potentially an important flagship species for the conservation of the coastal ecosystem, because diverse coastal environments are indispensable for its life cycle.Therefore, in order to protect not only the endangered species but also its natural habitat or biodiversity, the citizen-based monitoring of horseshoe crabs should be continued in this field.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"保全生態学研究, 13(2), pp.199-205; 2008","subitem_description_type":"Other"}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"66470","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Wada, Toshifumi"}]},{"nameIdentifiers":[{"nameIdentifier":"66471","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Yoneyama, Taihei"}]},{"nameIdentifiers":[{"nameIdentifier":"66472","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Hashiguchi, Daisuke"}]},{"nameIdentifiers":[{"nameIdentifier":"66473","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Nomura, Shunsuke"}]},{"nameIdentifiers":[{"nameIdentifier":"66474","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Itaya, Shinji"}]},{"nameIdentifiers":[{"nameIdentifier":"66475","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Shuuno, Mari"}]}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"保全生態学研究編集委員会"}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"日本生態学会"}]},"item_2_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11857952","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13424327","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"和田, 年史"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"米山, 太平"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"橋口, 大佑"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"野村, 俊介"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"板谷, 晋嗣"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"秀野, 真理"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-23"}],"displaytype":"detail","filename":"JJCE13_199.pdf","filesize":[{"value":"136.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"JJCE13_199.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/17092/files/JJCE13_199.pdf"},"version_id":"46ea8ba6-56c7-42c1-817f-295e34be84c6"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"絶滅危惧","subitem_subject_scheme":"Other"},{"subitem_subject":"象徴種","subitem_subject_scheme":"Other"},{"subitem_subject":"自然環境保全","subitem_subject_scheme":"Other"},{"subitem_subject":"環境教育","subitem_subject_scheme":"Other"},{"subitem_subject":"体幅組成解析","subitem_subject_scheme":"Other"},{"subitem_subject":"Endangered species","subitem_subject_scheme":"Other"},{"subitem_subject":"Flagship species","subitem_subject_scheme":"Other"},{"subitem_subject":"Natural environment conservation","subitem_subject_scheme":"Other"},{"subitem_subject":"Environmental education","subitem_subject_scheme":"Other"},{"subitem_subject":"Carapace width frequency analysis","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"福岡県津屋崎干潟におけるカブトガニ幼生の成長とモニタリング手法の開発","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"福岡県津屋崎干潟におけるカブトガニ幼生の成長とモニタリング手法の開発"}]},"item_type_id":"2","owner":"2","path":["315"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-02-19"},"publish_date":"2009-02-19","publish_status":"0","recid":"17092","relation_version_is_last":true,"title":["福岡県津屋崎干潟におけるカブトガニ幼生の成長とモニタリング手法の開発"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-17T20:26:11.801634+00:00"}
