Two characteristic benthos, namely Lucinoma annulata and Aricidea sp. were found in the innermost and deeper part of the bay. The characteristic occurrence of L. annulata in the deeper zone of the bay was formerly reported by MIYADI (1941). Comparing the record of distribution in the previous paper with results of the present study, upper boundary of vertical distribution of L. annulata has extended to shallower part in the present study, on the other hand, azoic area was found at the deepest part of the bay where the species formerly occurred. These changes of distributional area of L. annulata in recent years seemed to be mainly influenced by dissolved oxygen deficiency of bottom water and the resultant decrease of other competitive benthic animals. It was found that shell length of this species became large with increasing water depth, but the reason is not clearified yet.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"1975年11~12月,1976年7月,1977年11月の3回にわたり別府湾全域のベントス調査を行い,特に湾奥深部域のペソトスに関して以下のことが明らかとなった。1)湾奥深部域には二枚貝の1種でツキガイ科に属するツキガイモドキ Lucinoma annulata のほか,多毛類の Paraonidae に属する Aricidea sp.が特徴的に生息している。2)L. annulata の分布域は1940年当時とくらべた場合,浅海方向への拡がりをみせるとともに,湾奥最深部付近では本種の非生息域が出現した。これは別府湾の富栄養化による底唇水の貧酸素化現象の強化とそれに伴う L.annulata との競合性ペントスの減少が主な原因と考えられる。3)L. annulata の殻長は水深の増大とともに大型化する傾向のあることを認めたが,その原因は明らかではない。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"南西海区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Nansei Regional Fisheries Research Laboratory","subitem_publisher_language":"en"}]},"item_10002_radio_30":{"attribute_name":"item_10002_radio_30","attribute_value_mlt":[{"subitem_radio_item":"吉田","subitem_radio_language":"ja"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"nnf_k_12_105","subitem_relation_type_select":"Local"}}]},"item_10002_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"ja","subitem_relation_name_text":"日本農学文献記事索引(agriknowledge)"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://agriknowledge.affrc.go.jp/RN/2010212459","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"item_10002_source_id_11","attribute_value_mlt":[{"subitem_source_identifier":"AN00181988","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"item_10002_source_id_9","attribute_value_mlt":[{"subitem_source_identifier":"0388-841X","subitem_source_identifier_type":"PISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Tamai, Kyoichi","creatorNameLang":"en","creatorNameType":"Personal"},{"creatorName":"玉井, 恭一","creatorNameLang":"ja","creatorNameType":"Personal"},{"creatorName":"タマイ, キョウイチ","creatorNameLang":"ja-Kana","creatorNameType":"Personal"}],"familyNames":[{"familyName":"Tamai","familyNameLang":"en"},{"familyName":"玉井","familyNameLang":"ja"},{"familyName":"タマイ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Kyoichi","givenNameLang":"en"},{"givenName":"恭一","givenNameLang":"ja"},{"givenName":"キョウイチ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"1783","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"00372003","nameIdentifierScheme":"e-Rad_Researcher","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=00372003"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"item_resource_type","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"別府湾奥深部域に特徴的に生息する２種のベントス，Lucinoma annulata (二枚貝) と，Aricidea sp.
