A total of 50 taxa, mostly typical soil algae, were identified as potential colonizers. Sample material included dust on equipment and boots of expeditioners taken prior to boarding aircraft bound for Antarctica, and soil adherrent to fresh vegetables imported into Scott Base, Ross Island. 10 taxa were from genera unrecorded in the Ross Sea regions. Cylindrospermum (Cyanophyta) and Eustigmatos (Eustigmatophyta) are relatively easily recognised and their spread could be monitored if they became established in Antarctic habitats. However, there was no evidence of the establishment of any exogenous algae even in highly perturbed habitats close to Scott Base. Airborne dispersal within Antarctica was found to disperse algal propagules in the vicinity of Scott Base, although numbers were very low, being two orders of magnitude lower than those found in New Zealand. The ability of indigenous Antarctic algae and exogenous potential colonizers to survive freeze-thaw cycles, high salinity and desiccation was investigated in laboratory experiments. In general, strains isolated from dust on boots and equipment and from New Zealand air showed high survivability, as did the indigenous Antarctic strains. In contrast, strains isolated from soil on fresh vegetables imported into Antarctica had low survival similar to those isolated from a typical moist New Zealand garden soil. Suggestions are provided on how these preliminary investigations can be extended and improved.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00005227","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":"AA10819561","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":"Department of Plant and Microbial Sciences, University of Canterbury"},{"subitem_text_language":"en","subitem_text_value":"National Institute of Water and Atmosphere"}]},"item_1_text_3":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Proceeding"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1994-01-01"}],"displaytype":"detail","filename":"KJ00000767570.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000767570","url":"https://nipr.repo.nii.ac.jp/record/5227/files/KJ00000767570.pdf"},"version_id":"16185c65-e4dc-48d3-a938-fe9b09306e66"}]},"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":"A PRELIMINARY INVESTIGATION OF THE DIVERSITY, SURVIVABILITY AND DISPERSAL OF ALGAE INTRODUCED INTO ANTARCTICA BY HUMAN ACTIVITY (15th Symposium on Polar Biology)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A PRELIMINARY INVESTIGATION OF THE DIVERSITY, SURVIVABILITY AND DISPERSAL OF ALGAE INTRODUCED INTO ANTARCTICA BY HUMAN ACTIVITY (15th Symposium on Polar Biology)"}]},"item_type_id":"1","owner":"4","path":["643"],"pubdate":{"attribute_name":"公開日","attribute_value":"1994-01-01"},"publish_date":"1994-01-01","publish_status":"0","recid":"5227","relation_version_is_last":true,"title":["A PRELIMINARY INVESTIGATION OF THE DIVERSITY, SURVIVABILITY AND DISPERSAL OF ALGAE INTRODUCED INTO ANTARCTICA BY HUMAN ACTIVITY (15th Symposium on Polar Biology)"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:12:04.281903+00:00"}
