The present study was conducted over a range of 500 km along the Dempster Highway extending north from Dawson, Yukon Territory to Inuvik, the Northwest Territories, Canada. We collected a total of 24 wolf scats along side roads and rivers, in which as many as 14 million pollen grains/scat were found on an average. The analysis revealed that the wolves relied exclusively on the caribou during winter when scats are free of pollen grains, but increase their dependence on the beaver and other mammals up to over 50% in term of residuum occurrence in spring and summer when scats are respectively loaded primarily with arboreal and herbaceous pollen grains. This result was consistent with the local fauna of prey animals, the migration pattern of the caribou for breeding and wintering, availability of the beaver and other rodents as dictated by ice/snow cover, and breeding and cub rearing pattern of the wolves themselves. Thus it was concluded that the pollen analysis serves as a powerful and effective tool for identifying the seasonality of old scats, and therefore saves a great deal of time and effort to be devoted to finding fresh scats.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00006213","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_22":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"National Institute of Polar Research"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA11327019","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"College of Agriculture, Ehime University/Graduate School of Agriculture, Kyoto University/College of Agriculture, Ehime University"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2004-02-01"}],"displaytype":"detail","filename":"KJ00000673357.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000673357","url":"https://nipr.repo.nii.ac.jp/record/6213/files/KJ00000673357.pdf"},"version_id":"c19d3654-20f7-4526-89d4-b5849786c8ae"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"wolf, pollen, undigested residuum, seasonal diet, Dempster Highway","subitem_subject_language":"en","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Seasonal scatology of wolves along the Dempster Highway, northwestern Canada-an introduction of pollen analysis for dating old scats","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Seasonal scatology of wolves along the Dempster Highway, northwestern Canada-an introduction of pollen analysis for dating old scats"}]},"item_type_id":"1","owner":"4","path":["798"],"pubdate":{"attribute_name":"公開日","attribute_value":"2004-02-01"},"publish_date":"2004-02-01","publish_status":"0","recid":"6213","relation_version_is_last":true,"title":["Seasonal scatology of wolves along the Dempster Highway, northwestern Canada-an introduction of pollen analysis for dating old scats"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:04:48.742105+00:00"}
