Of 246 perennial streams (144.4km) found in 477(km)^2,119 (48.4%) or 27.8km (19.3%) were found infested with S. ochraceum. S. ochraceum larvae were found mainly from older impermeable rocks such as Tertiary lahars and lavas, arkosic conglomerate and Cretaceous granite. Although recent volcanic rocks have very few perennial streams due to permeability, they are important as water reservoirs for the underlying impermeable rocks. Quarternary alluvium showed high stream density, but no S. ochraceum larva was found from these streams, due probably to small channel slope. The area with Tertiary lahars and lavas is the most important bed of ochraceum-breeding streams, which roughly coincides with the onchocerciasis endemic area. Of total 1469 channel segments in this area, only 203 (13.8%) had perennial streams, of which 108 (53.2%) were infested with S. ochraceum. With increment of the channel order, the raito of channel segments with perennial streams increased, while, on the contrary, the ratio of perennial streams with S. ochraceum larvae decreased. No S. ochraceum larva was found in the fourth and fifth order channels. S. ochraceum larvae were found mainly in the uppermost part of the stream network, immediately below headsprings. The headsprings were found arranged nearly horizontally on the elevations 900m, 1100m and 1300-1460m above sea level.","subitem_description_type":"Abstract"}]},"item_4_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学留学生センター","subitem_description_type":"Other"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本衛生動物学会"}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AN00021948","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0424-7086","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_25":{"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":"Yamagata, Yoichi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Okazawa, Takao"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"Molina, Pedro Antonio"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-05"}],"displaytype":"detail","filename":"FO-PR-OKAZAWA-T-95(1982).pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"FO-PR-OKAZAWA-T-95(1982).pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/31341/files/FO-PR-OKAZAWA-T-95(1982).pdf"},"version_id":"2407b29b-bd26-4a65-842e-1863b068ef1d"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"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":"グァテマラにおける Simulium ochraceum の分布に関する地質・地形学的研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"グァテマラにおける Simulium ochraceum の分布に関する地質・地形学的研究"},{"subitem_title":"Geologic and geomorphologic studies on distribution of Simulium ochraceum (Diptera : Simuliidae) larvae in Guatemala","subitem_title_language":"en"}]},"item_type_id":"4","owner":"3","path":["2310"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-05"},"publish_date":"2017-10-05","publish_status":"0","recid":"31341","relation_version_is_last":true,"title":["グァテマラにおける Simulium ochraceum の分布に関する地質・地形学的研究"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-27T20:03:11.128272+00:00"}
