The present results indicated that P. nuntia and T.fragilis transferred vertically the cysts in the surface sediments due to ingestion, excretion and movement. However, the cyst densities in the surface sediments decreased more than expected from the vertical transfer to the deeper layers throughout the experimental periods. The accumulative number of vegetative cells of Alexandrium spp. that germinated from the culture sediments with P. nuntia and T. fragilis were lower as compared with those from the control sediments without any macrobenthos. It was considered that germination was suppressed by enclosing cysts in the fecal pellets and digestion of cysts, as well as the vertical transfer of cysts to the deeper layers. Therefore, it was suggested that the surface deposit feeders such as P. nuntia and T. fragilis have a significant role in decreasing the abundance of Alexandrium cysts in the surface sediments and suppressing the germination of them by the digestion, movement and enclosing in the fecal pellets.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"マクロベントスの活動が海底のアレキサンドリウム属シストの鉛直分布および発芽へ及ぼす影響を実験的に検討した。イソゴカイ及びシズクガイは摂食，排泄および移動等を通じて，表層のシストを鉛直的に運搬することが明らかとなった。しかし，表層のシストは，下層への運搬で説明される以上に著しく減少した。また，イソゴカイおよびシズクガイ飼育泥から直上水中に発芽した累積遊泳細胞数は，対照泥のそれに対し有意に少なかった。その原因はイソゴカイおよびシズクガイの活動によって，表層のシストが下層に運ばれることに加え，摂食，排泄によるシストの糞粒内への包埋やシスト数の減少によると考えられた。以上のことから，イソゴカイやシズクガイの表層堆積物食者は，シスト消化に加えて，底泥表層に堆積したシストの下層部への運搬や糞粒内への包埋によって，シスト数の低減効果や発芽抑制効果を持つことが示された。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"水産総合研究センター","subitem_publisher_language":"ja"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"fra_k_17_17","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_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/2010740406","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11589591","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1346-9894","subitem_source_identifier_type":"PISSN"}]},"item_10002_version_type_20":{"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_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":"","affiliationNameIdentifierScheme":"ISNI","affiliationNameIdentifierURI":"https://isni.org/isni/"}],"affiliationNames":[{"affiliationName":"","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Tsujino, Mutsumi","creatorNameLang":"en"},{"creatorName":"辻野, 睦","creatorNameLang":"ja"},{"creatorName":"ツジノ, ムツミ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Tsujino","familyNameLang":"en"},{"familyName":"辻野","familyNameLang":"ja"},{"familyName":"ツジノ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Mutsumi","givenNameLang":"en"},{"givenName":"睦","givenNameLang":"ja"},{"givenName":"ムツミ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"557","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"30371959","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=30371959"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-10-02"}],"filename":"fra_k_17_17.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_0","mimetype":"application/pdf","url":{"url":"https://fra.repo.nii.ac.jp/record/2010829/files/fra_k_17_17.pdf"},"version_id":"f26b7297-9a89-42dd-958f-92f9df0783ea"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Alexandrium spp.;
