Living\nspecimens were discriminated by the Rose Bengal staining method. One hundred and\nthirty-six samples were used for the mechanical analysis (EMERY settling-tube and pipette settling methods). Oceanographic observation on Kagoshima Bay has been carried out in alternate months from 1975 through 1979 by the staff of the Faculty of Fisheries, Kagoshima University. Those data were used for scrutinizing the environmental factors concerning the sea water characteristics in the area.\nThe intensity and direction of the bottom currents were inferred from the results of\nmechanical analyses of the bottom sediments and the oceanographic data. For all the\nspecies of which living specimens were recognized to occur, the ratio of the number of living specimens to the total (dead and living) number of individuals (L/Tl value) was calculated. Based on the L/Tl value, the relative rate of sedimentation at each sampling station was estimated. It has been pointed out that the L/Tl value well corresponds to the sedimentary environment inferred from the bottom current movement and the distribution of sediments, and it is a good index for sedimentary environment (ÔKI, 1986b, 1988). Taking the L/Tl value into consideration, the distribution patterns of number of individuals of planktonic foraminifera, of radiolaria and of benthonic foraminifera were\nillustrated (Figs. 19, 20 and 24). Further, the ratio of planktonic foraminifera to the total foraminifera was calculated on each sample and was discussed in relation to water depth. The total (dead and living) benthonic foraminiferal specimens were divided into six groups through the cluster analysis (DAVIS, 1973) based on the percentage frequency data. The relationship between each clustered group and the environmental condition of\nits distribution area was discussed. Based on the oceanographic data, results of mechanical analyses of bottom sediments and of cluster analysis of benthonic foraminifera, the following five populations of benthonic foraminifera corresponding to the distribution of the water masses were discriminated.\n\n1) Population A: Inhabiting the area under the influence of the open-sea water\nmass. Predominant species are Cibicidoides pseudoungerianus, Globocassidulina oriangulata, Paracassidulina quasicarinata, Florilus pauperatus and Discorbis mira.\n\n2) Population B: Inhabiting the area under the influence of the hyposaline water\nmass. Predominant species are Cymbaloporetta hemisphaerica, Buliminella elegantissima,\nBolivina ordinaria, Protelphidium schmitti and Pseudononion japonicum.\n\n3) Population C: Inhabiting the boundary area between the water masses different\nin salinity from each other. Predominant species are Uvigerina vadescens, Bulimina marginata and Globocassidulina oriangulata.\n\n4) Population D: In habiting the basin bottom under the influence of relatively stagnant water mass slightly mixed with the open-sea water. Predominant species is Bulimina marginata.\n\n5) Population E: Inhabiting the basin bottom under the influence of the water mass\nbeing stagnant through the year and scarcely exchanged with the open-sea water. Predominant species is, Eggerella scabra.\n\nThese populations of benthonic foraminifera in Kagoshima Bay were compared with\nthe similar ones hitherto reported from the seas around Japan.\nAll the species treated here including twelve new species and two subspecies were\ndescribed systematically.\n\n※ p.1~191, figs.1~68, tables 1~12, plates 1~22","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_6_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学","subitem_publisher_language":"ja"},{"subitem_publisher":"Kagoshima University","subitem_publisher_language":"en"}]},"item_6_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09160752","subitem_source_identifier_type":"PISSN"}]},"item_6_source_id_9":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN10088628","subitem_source_identifier_type":"NCID"}]},"item_6_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"457","subitem_subject_scheme":"NDC"}]},"item_6_text_44":{"attribute_name":"備考","attribute_value_mlt":[{"subitem_text_value":"Table 8 and Fig,. 3 are not included in this files."}]},"item_6_version_type_14":{"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":"Ôki, Kimihiko","creatorNameLang":"en"},{"creatorName":"オオキ, キミヒコ","creatorNameLang":"ja-Kana"},{"creatorName":"大木, 公彦","creatorNameLang":"ja"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2023-06-22"}],"displaytype":"detail","filename":"SouthPacificStudies10(1)pp1-191.pdf","filesize":[{"value":"58.9 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"SouthPacificStudies10(1)pp1-191","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/5170/files/SouthPacificStudies10(1)pp1-191.pdf"},"version_id":"e15fd7c1-f54e-4688-ad59-54233d0b32cf"}]},"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","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Ecological Analysis of Benthonic Foraminifera in Kagoshima Bay, South Kyûshû, Japan","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Ecological Analysis of Benthonic Foraminifera in Kagoshima Bay, South Kyûshû, Japan","subitem_title_language":"en"}]},"item_type_id":"6","owner":"18","path":["5578","34"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2013-01-22"},"publish_date":"2013-01-22","publish_status":"0","recid":"5170","relation_version_is_last":true,"title":["Ecological Analysis of Benthonic Foraminifera in Kagoshima Bay, South Kyûshû, Japan"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-02-26T00:35:34.386669+00:00"}
