Dominant amongst primary microbial colonizers are the phototrophic cyanobacteria and algae. Not only do they introduce organic nutrients into the microhabitat but they also have a structural function. Filaments of several dimensions frequently form a mesh over the surface of the soil. This mesh often has a canopy structure of fine filaments closely admixed with the mineral soil grains, overlain by a layer of broader, longer filaments. This structure may provide a rich grazing zone for micro-invertebrates such as protozoa and nematodes. Microbial filaments, clusters and unicells frequently have mucilaginous sheaths or capsules which may cement mineral grains together and improve soil crust stability. The combination of filaments and mucigel promotes the formation of microbial \"rafts\" which are dispersed by wind or water. The diverse microbiota of these compound propagules is likely to improve their chances of successful colonization of unpopulated soil surfaces. Phototrophic microbes can be distinguished in mixed natural communities of undisturbed soil crusts by selective filtration of their autofluorescence spectra. Heterotrophs can be distinguished after staining. The population can be selectively quantified by television image analysis (TVIA) using criteria of pigmentation, size and morphology.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00005098","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":"British Antarctic Survey, Natural Environment Research Council"}]},"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":"1990-03-01"}],"displaytype":"detail","filename":"KJ00000767474.pdf","filesize":[{"value":"2.3 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000767474","url":"https://nipr.repo.nii.ac.jp/record/5098/files/KJ00000767474.pdf"},"version_id":"d3a8e062-1e93-496a-8f5d-5b253ba92be3"}]},"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":"MICROBIAL COLONIZATION PROCESSES IN ANTARCTIC FELLFIELD SOILS : AN EXPERIMENTAL OVERVIEW (Eleventh Symposium on Polar Biology)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"MICROBIAL COLONIZATION PROCESSES IN ANTARCTIC FELLFIELD SOILS : AN EXPERIMENTAL OVERVIEW (Eleventh Symposium on Polar Biology)"}]},"item_type_id":"1","owner":"4","path":["639"],"pubdate":{"attribute_name":"公開日","attribute_value":"1990-03-01"},"publish_date":"1990-03-01","publish_status":"0","recid":"5098","relation_version_is_last":true,"title":["MICROBIAL COLONIZATION PROCESSES IN ANTARCTIC FELLFIELD SOILS : AN EXPERIMENTAL OVERVIEW (Eleventh Symposium on Polar Biology)"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:14:09.030283+00:00"}
