This view, however, does not follow from the published geological and molecular evidence. The former does indeed suggest that the LV basin dried out less than 15,000 years ago, but it does not provide any information about the species that re-colonized the new lake or that remained in the rivers draining the area. The molecular evidence is inconclusive with respect to the origin of the LV haplochromines because cichlids from critical regions around LV were not adequately sampled; and as far as the age of the LV haplochromines is concerned, it in fact led to an estimate of 250,000-750,000 years old. In the present study, mitochondrial DNA (control region) variation was determined by heteroduplex and sequencing analyses of more than 670 specimens collected at widely distributed East African riverine and lacustrine localities. The analyses revealed the existence of seven haplogroups (I-VII) distinguishable by characteristic substitutions. All endemic LV samples tested fell into one of these haplogroups (V) which, however, was also found to be present at various other localities, both riverine and lacustrine, outside LV. Within this haplogroup, four subgroups (VA through VD) could be distinguished, two of which (VB and VC) were represented in LV and at other localities. The great majority of the LV haplochromine species could be classified as belonging to the VC subgroup, which was found only in LV and in the rivers draining into it. Hence, while the endemic haplochromine species of LV could not have originated from a single founding population, the lake does harbour a large species flock which probably arose in situ.", "subitem_description_type": "Abstract"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "The Royal Society Publishing "}]}, "item_10001_relation_13": {"attribute_name": "PubMed番号", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10874756", "subitem_relation_type_select": "PMID"}}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_name": [{"subitem_relation_name_text": "10.1098/rspb.2000.1109 "}], "subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.1098/rspb.2000.1109", "subitem_relation_type_select": "DOI"}}]}, "item_10001_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "© The Royal Society "}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "09628452 ", "subitem_source_identifier_type": "ISSN"}]}, "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": "NAGL, Sandra "}], "nameIdentifiers": [{"nameIdentifier": "1675", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "TICHY, Herbert "}], "nameIdentifiers": [{"nameIdentifier": "1551", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "MAYER, Werner E"}], "nameIdentifiers": [{"nameIdentifier": "1627", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "TAKEZAKI, Naoko"}], "nameIdentifiers": [{"nameIdentifier": "1552", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "TAKAHATA, Naoyuki"}], "nameIdentifiers": [{"nameIdentifier": "778", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "KLEIN, Jan "}], "nameIdentifiers": [{"nameIdentifier": "1694", "nameIdentifierScheme": "WEKO"}]}]}, "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": "The origin and age of haplochromine fishes in Lake Victoria, East Africa", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "The origin and age of haplochromine fishes in Lake Victoria, East Africa"}, {"subitem_title": "The origin and age of haplochromine fishes in Lake Victoria, East Africa", "subitem_title_language": "en"}]}, "item_type_id": "10001", "owner": "21", "path": ["314"], "permalink_uri": "https://ir.soken.ac.jp/records/3773", "pubdate": {"attribute_name": "公開日", "attribute_value": "2013-07-09"}, "publish_date": "2013-07-09", "publish_status": "0", "recid": "3773", "relation": {}, "relation_version_is_last": true, "title": ["The origin and age of haplochromine fishes in Lake Victoria, East Africa"], "weko_shared_id": 21}
