The estuarine species <i>N. taeniurus</i> frequently occurred at several depth levels in the lower and middle estuaries with high salinity (29-34‰) at high tide, and at deeper water depths (below 50 cm) with high salinity (ca. 29‰) at low tide. The estuarine species <i>Fibramia amboinensis</i> was restricted to the middle estuary with a salinity range of 19-29‰ at both tides. The catadromous <i>Kuhlia rupestris</i> was restricted to the upper estuary with low salinity (ca. 3‰) at both tides. These results suggest that responses to tidal salinity fluctuations were species-specific in the tropical estuary. Some species actively relocated to select the most suitable salinity levels in accordance with the tides, while others remained in a spatially limited area at both tides, tolerating a broad range of salinity or adapting to particularly low salinity.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"公益社団法人 土木学会","subitem_publisher_language":"ja"},{"subitem_publisher":"Japan Society of Civil Engineers","subitem_publisher_language":"en"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.2208/jscejoe.72.I_1087"}}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"井上 太之","creatorNameLang":"ja"},{"creatorName":"INOUE Hiroyuki","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"村上 智一","creatorNameLang":"ja"},{"creatorName":"MURAKAMI Tomokazu","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"南條 楠土","creatorNameLang":"ja"},{"creatorName":"NANJO Kusuto","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"水谷 晃","creatorNameLang":"ja"},{"creatorName":"MIZUTANI Akira","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"河野 裕美","creatorNameLang":"ja"},{"creatorName":"KOHNO Hiroyoshi","creatorNameLang":"en"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_title":"西表島網取湾ウダラ川汽水域の潮汐に伴う塩分動態および優占する魚類の分布","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"西表島網取湾ウダラ川汽水域の潮汐に伴う塩分動態および優占する魚類の分布","subitem_title_language":"ja"},{"subitem_title":"TIDAL FLUCTUATION OF SALINITY AND DISTRIBUTION OF DOMINANT FISH SPECIES IN UDARA RIVER ESTUARY, AMITORI BAY, IRIOMOTE ISLAND.","subitem_title_language":"en"}]},"item_type_id":"40001","owner":"1","path":["1670839190650"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-04-27"},"publish_date":"2023-04-27","publish_status":"0","recid":"6096","relation_version_is_last":true,"title":["西表島網取湾ウダラ川汽水域の潮汐に伴う塩分動態および優占する魚類の分布"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-04-27T05:19:43.289495+00:00"}
