In snowy areas, all species combined, as well as F. crenata alone, showed constant regeneration, with parameter b approximate to-1.6 for the power function y=ax(b) (x=DBH, y=density), which is related to the DBH-class distribution. The good fit of the data to the function suggests that beech regenerates constantly with self-thinning patch dynamics. Parameter a, which indicates the abundance of small trunks, was high. Furthermore, the mean J/C ratio was approximate to 8, i.e., each parent beech tree produced eight juveniles. These results suggest that beech regenerates constantly with gap dynamics in snowy beech forests on the Japan Sea side of Japan (snowy). However, the fit of F. crenata was lower and nonsignificant in some forests in less snowy areas, despite the high fit of all species combined. In these areas, the mean of a was low, and b was often near zero for F. crenata regressions. These results suggest that the abundance of beech was low, and self-thinning was not evident because of the initial low abundance. Moreover, the mean J/C ratio was \u003c 1.0, suggesting that juvenile density was lower than that of canopy trees. Thus, the regeneration of F. crenata on the Pacific Ocean side of Japan (less snowy) is rather sporadic. Less snowy conditions may promote seed desiccation, predation of beechnuts and seedlings, and water stress. Lower F. crenata density may also reduce predator satiation and wind pollination."}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Shimano,  Koji"}], "nameIdentifiers": [{"nameIdentifier": "36769", "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": "Fagus crenata.pdf", "filesize": [{"value": "724.5 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 724500.0, "url": {"label": "Fagus crenata.pdf", "url": "https://soar-ir.repo.nii.ac.jp/record/11990/files/Fagus crenata.pdf"}, "version_id": "a4369440-74eb-4ab1-a550-865dd41c01ae"}]}, "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": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Differences in beech (Fagus crenata) regeneration between two types of Japanese beech forest and along a snow gradient", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Differences in beech (Fagus crenata) regeneration between two types of Japanese beech forest and along a snow gradient", "subitem_title_language": "en"}]}, "item_type_id": "6", "owner": "1", "path": ["1170"], "permalink_uri": "http://hdl.handle.net/10091/247", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2007-06-13"}, "publish_date": "2007-06-13", "publish_status": "0", "recid": "11990", "relation": {}, "relation_version_is_last": true, "title": ["Differences in beech (Fagus crenata) regeneration between two types of Japanese beech forest and along a snow gradient"], "weko_shared_id": -1}
