The data was obtained from the satellite tracking of two female Tibetan antelopes that were collared with satellite transmitters and have been tracked from August 2007 to April 2009. Analysis of the locality data (LC) obtained, shows that both antelopes were migrant individuals, they shared the same calving ground surrounding lake Huiten (or Zhuonai lake), but different wintering pastures. Each antelope covered 250-300 km from the wintering to summer pastures. Annual range consisted of a core area that was used for at least 9 months; a calving ground used for a short time (from 8-20 days); and temporal pastures used during migration to and from the calving ground. Seasonal migration cycle was about 3 months, 27-30 days to reach the calving ground; 8-20 days staying there; and 36-40 days returning to the core area. Examination of the spatial distribution during migration showed that both chiru crossed the Qinghai–Tibetan railway (QTR) and the Golmud-Lhasa highway (GLH) at least two times, and reached calving ground (118-120 km from there) in 8 days, maintaining an average speed of 15 km per day. However, the return migration took twice as long (from 14 to 16 days). Each time, after reaching the QTR and GLH, the antelopes spent 20-40 days in that area, probably looking for passages and waiting. So far, we suppose that the QTR and the GLH have become a hindrance to the migration of the Tibetan antelopes and seriously delay their movement to and from the calving area. Extended aggregation of the herds of Tibetan antelopes along the QTR and the GLH may impact negatively with increased mortality among offspring, the spread of various diseases and overgrazing of pastures.", "subitem_description_type": "Abstract"}]}, "item_2_publisher_36": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Elsevier"}]}, "item_2_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1016/j.asr.2011.02.015", "subitem_relation_type_select": "DOI"}}]}, "item_2_source_id_10": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0273-1177", "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": "Hoshino, Buho"}], "nameIdentifiers": [{"nameIdentifier": "3803", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Jiang, Z."}], "nameIdentifiers": [{"nameIdentifier": "3804", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Liu, C."}], "nameIdentifiers": [{"nameIdentifier": "3805", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Yoshida, T."}], "nameIdentifiers": [{"nameIdentifier": "3806", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Mahamut, Halik"}], "nameIdentifiers": [{"nameIdentifier": "3807", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kaneko, M."}], "nameIdentifiers": [{"nameIdentifier": "3808", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Asakawa, M"}], "nameIdentifiers": [{"nameIdentifier": "3809", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Motokawa, M."}], "nameIdentifiers": [{"nameIdentifier": "3810", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kaji, K."}], "nameIdentifiers": [{"nameIdentifier": "3811", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Wu, X."}], "nameIdentifiers": [{"nameIdentifier": "3812", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Otaishi, N."}], "nameIdentifiers": [{"nameIdentifier": "3813", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ganzorig, Sumiya"}], "nameIdentifiers": [{"nameIdentifier": "3814", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Masuda, R."}], "nameIdentifiers": [{"nameIdentifier": "3815", "nameIdentifierScheme": "WEKO"}]}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "China", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Tibetan plateau", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Chiru", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Distribution", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Satellite tracking", "subitem_subject_scheme": "Other"}, {"subitem_subject": "ARGOS", "subitem_subject_scheme": "Other"}]}, "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": "Preliminary study on migration pattern of the Tibetan antelope (Pantholops hodgsonii) based on satellite tracking", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Preliminary study on migration pattern of the Tibetan antelope (Pantholops hodgsonii) based on satellite tracking"}]}, "item_type_id": "2", "owner": "3", "path": ["24"], "permalink_uri": "http://hdl.handle.net/10659/3029", "pubdate": {"attribute_name": "公開日", "attribute_value": "2013-06-04"}, "publish_date": "2013-06-04", "publish_status": "0", "recid": "1667", "relation": {}, "relation_version_is_last": true, "title": ["Preliminary study on migration pattern of the Tibetan antelope (Pantholops hodgsonii) based on satellite tracking"], "weko_shared_id": -1}

内容記述 | The spatial and temporal patterns of the endangered Tibetan antelope or chiru (Pantholops hodgsonii) have been studied using satellite-based ARGOS platform transmitter terminal (PTT) tracking data. The data was obtained from the satellite tracking of two female Tibetan antelopes that were collared with satellite transmitters and have been tracked from August 2007 to April 2009. Analysis of the locality data (LC) obtained, shows that both antelopes were migrant individuals, they shared the same calving ground surrounding lake Huiten (or Zhuonai lake), but different wintering pastures. Each antelope covered 250-300 km from the wintering to summer pastures. Annual range consisted of a core area that was used for at least 9 months; a calving ground used for a short time (from 8-20 days); and temporal pastures used during migration to and from the calving ground. Seasonal migration cycle was about 3 months, 27-30 days to reach the calving ground; 8-20 days staying there; and 36-40 days returning to the core area. Examination of the spatial distribution during migration showed that both chiru crossed the Qinghai–Tibetan railway (QTR) and the Golmud-Lhasa highway (GLH) at least two times, and reached calving ground (118-120 km from there) in 8 days, maintaining an average speed of 15 km per day. However, the return migration took twice as long (from 14 to 16 days). Each time, after reaching the QTR and GLH, the antelopes spent 20-40 days in that area, probably looking for passages and waiting. So far, we suppose that the QTR and the GLH have become a hindrance to the migration of the Tibetan antelopes and seriously delay their movement to and from the calving area. Extended aggregation of the herds of Tibetan antelopes along the QTR and the GLH may impact negatively with increased mortality among offspring, the spread of various diseases and overgrazing of pastures. | |||||
