Each spring chiru females migrate several hundred kilometers from wintering sites to calving sites. During the migration antelopes have to cross the Qinghai-Tibet Railway (QTR) and Qinghai-Tibet Highway (QTH), which might cause negative consequences to animals. Therefore, the purpose of this study is to understand ecology and clarify the effect of QTR/QTH on the chiru.【Methods】1. To clarify the effect of QTR/QTH, the Animal Home Range using ARGOS PTT data was estimated. 2. In order to clarify the habitat selection of chiru, the home range of each individual animal was analyzed, wintering sites were classified and distribution model of the species was created. 3.Population census was conducted on transects in chiru habitat, the herd structure and herd size was investigated. Based on these results, the movement pattern of chiru around QTR/QTH was estimated.【Results】1. Analysis of the home range of chiru inhabiting neighboring to QTR/QTH area, showed that the width of the migration corridor was wider in those habitats. So far, artificial construction such as QTR/QTH influenced this effect on the seasonal migration behavior of chiru. 2. Analysis of the habitat selection of chiru has revealed three wintering sites in the Sanjiangyan area. Distance from the lake and altitude is most important factor for the habitat selection of wintering chiru. The selection of calving sites by breeding chiru is greatly affected by the distance from the lake. 3. During field observation only 27% of adult females were with offspring. The peak of migrating chiru in QTR/QTH is observed in 2nd of August, when number of migrating animals was accounted for approximately 30% of the total observed population. When crossing QTR/QTH, the herd of chiru is using the underpass in the form of detour from the shortest route, which is consistent with findings of satellite-based study.","subitem_description_type":"Abstract"}]},"item_3_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"9846","nameIdentifierScheme":"WEKO"}],"names":[{"name":"ナカザワ, タカシ"}]}]},"item_3_version_type_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"仲澤, 峻"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-09-19"}],"displaytype":"detail","filename":"Nakazawa_syuuron.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Nakazawa_syuuron.pdf","url":"https://rakuno.repo.nii.ac.jp/record/3751/files/Nakazawa_syuuron.pdf"},"version_id":"1ed27c3f-16eb-468f-a690-25294dd11274"}]},"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":"thesis","resourceuri":"http://purl.org/coar/resource_type/c_46ec"}]},"item_title":"ココシリで繁殖するチベットアンテロープ（Pantholops hodgsonii） のホームレンジおよび生息地の環境利用について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ココシリで繁殖するチベットアンテロープ（Pantholops hodgsonii） のホームレンジおよび生息地の環境利用について"}]},"item_type_id":"3","owner":"3","path":["39"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-06-11"},"publish_date":"2014-06-11","publish_status":"0","recid":"3751","relation_version_is_last":true,"title":["ココシリで繁殖するチベットアンテロープ（Pantholops hodgsonii） のホームレンジおよび生息地の環境利用について"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-19T08:33:28.606614+00:00"}
