The lecithotrophy of larvae is considered an adaptation to limited food conditions in the freshwater environment. Furthermore, faster development and settlement behaviours that large larvae \nexhibit are considered adaptations that allow the larvae to stay in or near parental habitats in fast-flowing \nstreams. We therefore hypothesized that the facultative lecithotrophic larvae of landlocked shrimps might better adapt to limited food conditions as their large body size develops, an adaptation to maintain \nhabitat position in flowing streams, than do planktotrophic larvae of companion amphidromous species \ndeveloping in the sea. To test this hypothesis, we compared the larval feeding habits and size of two closely related species in the genus Paratya: the amphidromous P. compressa, with planktotrophic larvae, and the landlocked P. improvisa, with facultative lecithotrophic larvae. Larvae were reared by being fed commercially preserved or cultured phytoplankton (Tetraselmis sp.) and cultured zooplankton rotifers. \nParatya compressa larvae did not survive, but P. improvisa larvae did develop into the juvenile stage under poor feeding conditions with preserved Tetraselmis alone, supporting our hypothesis of the effects of different larval feeding habits in amphidromous and landlocked atyid shrimp species. Hatchlings were \nlarger and larval duration was shorter in P. improvisa than in P. compressa. Paratya improvisa larvae exhibited settlement behaviour beginning with the early zoeal stage. Our results also highlighted the retention strategy by which landlocked P. improvisa larvae stay in or near parental habitats"}]},"item_3_description_63":{"attribute_name":"研究課題番号","attribute_value_mlt":[{"subitem_description":"17K00578"}]},"item_3_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Academia Sinica"}]},"item_3_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.6620/ZS.2020.59-70","subitem_relation_type_select":"DOI"}}]},"item_3_relation_13":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"Publisher's Version/PDF (OpenAccess)"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.6620/ZS.2020.59-70","subitem_relation_type_select":"DOI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"KAKEN研究課題: 温暖化が変温動物の生活史に及ぼす影響評価：両側回遊型淡水産コエビ類をモデルとして"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-17K00578/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"研究代表者: 濱崎活幸 (東京海洋大学)"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://nrid.nii.ac.jp/ja/nrid/1000090377078/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"Academia Sinica"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.sinica.edu.tw/en","subitem_relation_type_select":"URI"}}]},"item_3_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1021-5506","subitem_source_identifier_type":"ISSN"}]},"item_3_subject_62":{"attribute_name":"件名","attribute_value_mlt":[{"subitem_subject":"科学研究費研究成果"}]},"item_3_subject_64":{"attribute_name":"科学研究費研究課題","attribute_value_mlt":[{"subitem_subject":"温暖化が変温動物の生活史に及ぼす影響評価：両側回遊型淡水産コエビ類をモデルとして"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Hamasaki, Katsuyuki"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"Okada, Masakazu"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nishimoto, Sota"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Dan, Shigeki"}],"nameIdentifiers":[{},{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Larval development","subitem_subject_scheme":"Other"},{"subitem_subject":"Larval survival","subitem_subject_scheme":"Other"},{"subitem_subject":"Feeding habit","subitem_subject_scheme":"Other"},{"subitem_subject":"Lecithotrophy","subitem_subject_scheme":"Other"},{"subitem_subject":"Retention strategy","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article"}]},"item_title":"Larval Performance of Amphidromous and Landlocked Atyid Shrimp Species in the Genus  Paratya under Different Feeding Conditions","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Larval Performance of Amphidromous and Landlocked Atyid Shrimp Species in the Genus  Paratya under Different Feeding Conditions","subitem_title_language":"en"}]},"item_type_id":"3","owner":"15","path":["470","533","468","469"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2021-09-21"},"publish_date":"2021-09-21","publish_status":"0","recid":"2209","relation_version_is_last":true,"title":["Larval Performance of Amphidromous and Landlocked Atyid Shrimp Species in the Genus  Paratya under Different Feeding Conditions"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2023-10-24T07:14:28.784410+00:00"}
