candel)やハマボウ(Hibiscus hamabo)からなるマングローブ林が広がっており, その周辺にはウミニナBatillaria multiformis (Lischke), カワアイCerithideopsilla djadjariensis (K.martin),ヘナタリCerithideopsilla cingulata (Gmelin),フトヘナタリCerithidea rhizophorarum (A.Adams) の4種の巻貝が生息している.これまでウミニナについては,発生様式,分布については研究されてきたが,新規加入時期などの生活史についてはあまり研究されていない.本研究ではウミニナの生活史を明らかにする目的の一つとして,より広範囲な地域で調査した.\n調査は2002 年2 月から2003 年1 月の期間に毎月1 回,大潮の日の干潮時にコドラート内の砂泥を集めて,2 mm メッシュのふるい内で洗ったものを持ち帰った.計測はサンプルから肉眼で個体を取り出し,種毎に分類し,幼貝は顕微鏡を利用して同定した.ウミニナは殻高をノギスで0.1mm 単位で計測して記録した.\nその結果,各調査区の間で新規加入の時期に差があることが分かった.上流部から下流部に行くに従って,加入時期が1 ヶ月ほど早まっていった.また,殻高サイズ頻度分布においても下流部のほうが上流部に比べ大きいサイズピークを示していた.個体数の季節的変動は,全調査区において,春にピークとなり,夏にかけて減少し再び秋に向けて増加していることが分かった.これは,春には生殖活動のために高密度になるためであり,秋には幼貝と中型個体の増加のためだと考えられる.","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_6_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島県自然環境保全協会","subitem_publisher_language":"ja"}]},"item_6_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"鹿児島県自然環境保全協会","subitem_rights_language":"ja"}]},"item_6_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18827551","subitem_source_identifier_type":"PISSN"}]},"item_6_source_id_9":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA12599025","subitem_source_identifier_type":"NCID"}]},"item_6_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"460","subitem_subject_scheme":"NDC"}]},"item_6_version_type_14":{"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":"吉田,
