It is necessary to obtain a fundamental knowledge of these marine forest communities from an ecological point of view in order to develop the appropriate technologies for their afforestation and management. \nThis paper deals with the seasonal changes is composition of stipe length and age distribution of the population of Eisenia and Ecklonia measured continuously from June, 1982 to December, 1984 by the quadrate in the coastal area of Shima peninsula, Mie Prefecture.  \nThree to four age groups in the Eisenia population and three to five in the Ecklonia were divided according to the frequency distribution of stipe length by the method of Akamine (1982) for analysis on a normal distribution curve. Each of the age groups so divided was pursued continuously during the period of measurement. \nIn the Eisenia population, it was observed that large fronds more than three years old have a tendency to occupy the greater portions of frequency distribution of stipe length, preventing young fronds of one or two years old in germination and growth. As for the Ecklonia population, a stable forest was composed of fronds of all age groups within the life span of this species with no particularly large portion frequency distribution of stipe length, except for the population disturbed by the hard wave action of a typhoon or other factors. \nThe newly germinated groups with many young fronds were divided into two groups which had a different average stipe length. The reason for this difference is as follows: the growth rate of stipe length was effected by the germination time lag and the different light conditions in the place where the two groups of fronds were germinated. \nFrom these observations, it is thought that the major factor influencing the seasonal changes in age distribution of the Eisenia and Ecklonia populations is the light condition as related to the vertical population density.", "subitem_description_type": "Abstract"}]}, "item_4_publisher_30": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "三重大学水産学部"}]}, "item_4_source_id_7": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0287-5772", "subitem_source_identifier_type": "ISSN"}]}, "item_4_source_id_9": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AN0023428X", "subitem_source_identifier_type": "NCID"}]}, "item_4_subject_16": {"attribute_name": "日本十進分類法", "attribute_value_mlt": [{"subitem_subject": "474", "subitem_subject_scheme": "NDC"}]}, "item_4_text_18": {"attribute_name": "その他のタイトル", "attribute_value_mlt": [{"subitem_text_value": "Ecological studies on Eisenia bicyclis and Ecklonia cava Communities - V : Seasonal changes in composition of stipe length and age groups"}]}, "item_4_text_63": {"attribute_name": "ノート", "attribute_value_mlt": [{"subitem_text_value": "Agropedia提供データ"}]}, "item_4_text_65": {"attribute_name": "資源タイプ（三重大）", "attribute_value_mlt": [{"subitem_text_value": "Departmental Bulletin Paper / 紀要論文"}]}, "item_4_version_type_15": {"attribute_name": "著者版フラグ", "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": "喜田, 和四郎"}], "nameIdentifiers": [{"nameIdentifier": "12036", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "前川, 行幸"}], "nameIdentifiers": [{"nameIdentifier": "12037", "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": "2017-02-18"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "AN0023428X0001212.pdf", "filesize": [{"value": "511.8 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 511800.0, "url": {"label": "AN0023428X0001212.pdf", "url": "https://mie-u.repo.nii.ac.jp/record/5622/files/AN0023428X0001212.pdf"}, "version_id": "5d157f51-f9e2-4838-a85c-b156c313e882"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Eisenia bicyclis", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Ecklonia cava", "subitem_subject_scheme": "Other"}, {"subitem_subject": "stipe length age", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "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": "アラメ・カジメ群落に関する生態学的研究 - V : 茎長組成および年齢群の季節変化", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "アラメ・カジメ群落に関する生態学的研究 - V : 茎長組成および年齢群の季節変化"}]}, "item_type_id": "4", "owner": "3", "path": ["431"], "permalink_uri": "http://hdl.handle.net/10076/3490", "pubdate": {"attribute_name": "公開日", "attribute_value": "2007-06-18"}, "publish_date": "2007-06-18", "publish_status": "0", "recid": "5622", "relation": {}, "relation_version_is_last": true, "title": ["アラメ・カジメ群落に関する生態学的研究 - V : 茎長組成および年齢群の季節変化"], "weko_shared_id": 3}
