In particular, since its discovery in 2001, much attention has been paid to a so-called \u0027scaly-foot\u0027 gastropod because of its unique iron-sulfide-coated dermal sclerites and the chemosynthetic symbioses in its various tissues. Despite increasing interest in the faunal assemblages at Indian Ocean hydrothermal vents, only two hydrothermal vent fields have been investigated in the Indian Ocean. Here we report two newly discovered hydrothermal vent fields, the Dodo and Solitaire fields, which are located in the Central Indian Ridge (CIR) segments 16 and 15, respectively. Chemosynthetic faunal communities at the Dodo field are emaciated in size and composition. In contrast, at the Solitaire field, we observed faunal communities that potentially contained almost all genera found at CIR hydrothermal environments to date, and even identified previously unreported taxa. Moreover, a new morphotype of \u0027scaly-foot\u0027 gastropod has been found at the Solitaire field. The newly discovered \u0027scaly-foot\u0027 gastropod has similar morphological and anatomical features to the previously reported type that inhabits the Kairei field, and both types of \u0027scaly-foot\u0027 gastropods genetically belong to the same species according to analyses of their COI gene and nuclear SSU rRNA gene sequences. However, the new morphotype completely lacks an iron-sulfide coating on the sclerites, which had been believed to be a novel feature restricted to \u0027scaly-foot\u0027 gastropods. Our new findings at the two newly discovered hydrothermal vent sites provide important insights into the biodiversity and biogeography of ventendemic ecosystems in the Indian Ocean.", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "PUBLIC LIBRARY SCIENCE", "subitem_publisher_language": "en"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1371/journal.pone.0032965"}}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "1932-6203", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Kentaro Nakamura", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Hiromi Watanabe", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Junichi Miyazaki", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Ken Takai", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Shinsuke Kawagucci", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Takuro Noguchi", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Suguru Nemoto", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Tomo-o Watsuji", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Takuya Matsuzaki", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Takazo Shibuya", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Kei Okamura", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Masashi Mochizuki", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Yuji Orihashi", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Tamaki Ura", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Akira Asada", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Daniel Marie", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Meera Koonjul", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Manvendra Singh", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Girish Beedessee", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Mitrasen Bhikajee", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Kensaku Tamaki", "creatorNameLang": "en"}]}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_title": "Discovery of New Hydrothermal Activity and Chemosynthetic Fauna on the Central Indian Ridge at 186 degrees-206 degrees S", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Discovery of New Hydrothermal Activity and Chemosynthetic Fauna on the Central Indian Ridge at 186 degrees-206 degrees S", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "1", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/5153", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-03-30"}, "publish_date": "2023-03-30", "publish_status": "0", "recid": "5153", "relation": {}, "relation_version_is_last": true, "title": ["Discovery of New Hydrothermal Activity and Chemosynthetic Fauna on the Central Indian Ridge at 186 degrees-206 degrees S"], "weko_shared_id": -1}
