Gadut). This region characterized by heavy rainfall, annual precipitation reached 6000-8000mm.\nNumber of tree species of these plots given the richest flora in tropical region; over 300 species in 1 ha Pinang Pinang plot (DBH > 8cm), and 276 species in narrow 0.33 ha of Pinang Pinang Atas transect (DBH > 5cm). \nThis richness caused by:\n(1) Multistratum construction of the foot hill forest resulted vertical complexity of the tree species.\n(2) Species distributions depend by topographical gradients and mosaic environmental factors resulted horizontal complexity of forest structure.\n(3) Gap regeneration process of the forest resulted to complexity mosaic distribution pattern of tree species.\nThese things will contribute to the richness of species number of the foot hill plots.\nThese plots have special tree genera. The genus Eugenia (Myrtaceae) and Diospyros (Ebenaceae) have many species in a narrow area of the plots. Species of these genara closely related and occupied same habitat (under the canopy tree layer). Twenty-five genera belonging to the family Sapotaceae, Fagaceae, Burseraceae, and others characterized by this strange speciation group that represented more than 40% of tree species of the plots.\nThe tree species that only one tree appears in plots are much too. In Pinang Pinang Atas transect, for example, 112 species, ca. 2/5 of 276 species, found only one tree in the plot.\nStudies about speciation of the various tree groups are necessary for understanding of richness in the tropical rain forest.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_30002_file35":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-08-30"}],"displaytype":"detail","fileDate":[{"fileDateType":"Issued","fileDateValue":"1994-03-01"}],"filename":"wspaper2-_64-75.pdf","filesize":[{"value":"2.17MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"wspaper2-_64-75","objectType":"fulltext","url":"https://jircas.repo.nii.ac.jp/record/2000462/files/wspaper2-_64-75.pdf"},"version_id":"4d5b8f64-0a71-476f-805c-4f52e94196ba"}]},"item_30002_identifier_registration17":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.34556/0002000462","subitem_identifier_reg_type":"JaLC"}]},"item_30002_language12":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_30002_publisher10":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"農林水産省国際農林水産業研究センター","subitem_publisher_language":"ja"}]},"item_30002_relation18":{"attribute_name":"関連情報","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"ja","subitem_relation_name_text":"農業限界地における環境資源利用技術の開発と今後の研究推進 ; 国際熱帯林研究をめぐる諸問題"}],"subitem_relation_type":"isPartOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.34556/0002000448","subitem_relation_type_select":"DOI"}}]},"item_30002_resource_type13":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_30002_source_identifier22":{"attribute_name":"収録物識別子","attribute_value_mlt":[{"subitem_source_identifier":"1340-6094","subitem_source_identifier_type":"PISSN"},{"subitem_source_identifier":"AN10446728","subitem_source_identifier_type":"NCID"}]},"item_30002_title0":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"3. 熱帯多雨林の種の多様性と動態 : 西スマトラの事例から (国際熱帯林研究をめぐる諸問題)","subitem_title_language":"ja"},{"subitem_title":"3.
