Although resting eggs are often thought to play an important role in establishing spring populations of Daphnia, the experimental results suggest that overwintering free-living individuals can also contribute to it. The significance of the overwintering stages in Daphnia population dynamics is discussed.", "subitem_description_type": "Abstract"}]}, "item_10_description_30": {"attribute_name": "資源タイプ（コンテンツの種類）", "attribute_value_mlt": [{"subitem_description": "Article", "subitem_description_type": "Other"}]}, "item_10_description_31": {"attribute_name": "フォーマット：mimeタイプ", "attribute_value_mlt": [{"subitem_description": "application/pdf", "subitem_description_type": "Other"}]}, "item_10_description_5": {"attribute_name": "引用", "attribute_value_mlt": [{"subitem_description": "信州大学理学部紀要 35(1): 31-42(2000)", "subitem_description_type": "Other"}]}, "item_10_publisher_4": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "信州大学理学部"}]}, "item_10_select_64": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_10_source_id_35": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0583-063X", "subitem_source_identifier_type": "PISSN"}]}, "item_10_source_id_39": {"attribute_name": "NII ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0583-063X", "subitem_source_identifier_type": "PISSN"}]}, "item_10_source_id_40": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AA00697923", "subitem_source_identifier_type": "NCID"}]}, "item_10_text_66": {"attribute_name": "sortkey", "attribute_value_mlt": [{"subitem_text_value": "03"}]}, "item_1627890569677": {"attribute_name": "出版タイプ", "attribute_value_mlt": [{"subitem_version_resource": "http://purl.org/coar/version/c_970fb48d4fbd8a85", "subitem_version_type": "VoR"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "HANAZATO,  Takayuki", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "36882", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2015-09-28"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "Science35-01-03.pdf", "filesize": [{"value": "619.1 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 619100.0, "url": {"label": "Science35-01-03.pdf", "url": "https://soar-ir.repo.nii.ac.jp/record/12029/files/Science35-01-03.pdf"}, "version_id": "602757c5-87e8-4e40-b8af-d8ddfe76b37b"}]}, "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": "Contribution of Resting Eggs and Overwintering Free-living Individuals to Establishment of Spring Daphnia Populations : A Suggestion Obtained from Studies using Experimental Ponds", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Contribution of Resting Eggs and Overwintering Free-living Individuals to Establishment of Spring Daphnia Populations : A Suggestion Obtained from Studies using Experimental Ponds", "subitem_title_language": "en"}]}, "item_type_id": "10", "owner": "1", "path": ["1184"], "permalink_uri": "http://hdl.handle.net/10091/10667", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2010-10-06"}, "publish_date": "2010-10-06", "publish_status": "0", "recid": "12029", "relation": {}, "relation_version_is_last": true, "title": ["Contribution of Resting Eggs and Overwintering Free-living Individuals to Establishment of Spring Daphnia Populations : A Suggestion Obtained from Studies using Experimental Ponds"], "weko_shared_id": -1}
