In addition we studied reproductive strategy of corals. The timing and mechanism of transmission of zooxanthellae from maternal tissue to oocytes m corals writ vertically transmitted symbionts were studied. We also described how zooxanthellae became restricted to gastrodermal cells during development of these corals. We analyzed phylogeny of zooxanthellae associated with corals with different modes of symbiont acquisition. The result suggests that even corals with vertically transmitted symbionts can acquire zooxanthellae from outside. We analyzed phylogeny of zooxanthellae associated with corals with different modes of symbiont acquisition. The result suggests that even corals with vertically transmitted symbionts can acquire zooxanthellae from outside. In colonial ascidians that have symbiotic prochloron, larvae had a special organ for acquisition of algae from their parent. Thus prochloron might play important function in ascidian physiology. However, prochloron resides on outer surface of the ascidians, sugesting that their role in nutrition might be small Colonies of Pocillopora damicornis in Kaneohe Bay did not harbor Trapzia crabs, though tey accepted experimentally provided Trapezia crabs. This suggests the possibility that there is no recruitment of the crabs in this area due to rurrent conitions or that other organisms interfere the association between the coral and Trapezia crabs. How clonal density of a Hawaiian coral, Montipora verrucosa affects its energy allocation to sexual reproduction was studied experimentally and theoretically.", "subitem_description_type": "Other"}, {"subitem_description": "未公開：P.6以降（別刷論文のため）", "subitem_description_type": "Other"}, {"subitem_description": "研究報告書", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "日高道雄"}]}, "item_1617186702042": {"attribute_name": "Language", "attribute_value_mlt": [{"subitem_1551255818386": "jpn"}]}, "item_1617186783814": {"attribute_name": "Identifier", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/20.500.12000/11489"}]}, "item_1617186920753": {"attribute_name": "Source Identifier", "attribute_value_mlt": [{"subitem_1522646500366": "NCID", "subitem_1522646572813": "BA64356057"}]}, "item_1617187056579": {"attribute_name": "Bibliographic Information", "attribute_value_mlt": [{"bibliographicIssueDates": {"bibliographicIssueDate": "9999-01-01", "bibliographicIssueDateType": "Issued"}, "bibliographicPageStart": "none"}]}, "item_1617258105262": {"attribute_name": "Resource Type", "attribute_value_mlt": [{"resourcetype": "research report", "resourceuri": "http://purl.org/coar/resource_type/c_18ws"}]}, "item_1617265215918": {"attribute_name": "Version Type", "attribute_value_mlt": [{"subitem_1522305645492": "VoR", "subitem_1600292170262": "http://purl.org/coar/version/c_970fb48d4fbd8a85"}]}, "item_1617605131499": {"attribute_name": "File", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "download_preview_message": "", "file_order": 0, "filename": "11694223.pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "", "size": 0, "url": {"objectType": "fulltext", "url": "https://u-ryukyu.repo.nii.ac.jp/record/2004757/files/11694223.pdf"}, "version_id": "2b88eb0b-1d13-4584-b9bc-bb131c84a3bb"}]}, "item_title": "サンゴ礁の共生系に関する共同研究", "item_type_id": "15", "owner": "1", "path": ["1642838403123", "1642838406414"], "permalink_uri": "http://hdl.handle.net/20.500.12000/11489", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2009-07-27"}, "publish_date": "2009-07-27", "publish_status": "0", "recid": "2004757", "relation": {}, "relation_version_is_last": true, "title": ["サンゴ礁の共生系に関する共同研究"], "weko_shared_id": -1}
