The egg production rates (EPs) and weight-specific egg production rates (SEPs) of two common copepods, Acartia longiremis and Temora longicornis, were studied under experimental conditions in Dalnezelenetskaya Bay (southern Barents Sea) during summer. The average EP and SEP at 5-10 °C were 4.7 ± 0.4 eggs female-1 day-1 and 0.025 ± 0.002 day-1, respectively, for A. longiremis and 13.1 ± 0.9 eggs female-1 day-1 and 0.075 ± 0.006 day-1, respectively, for T. longicornis. EP and SEP were significantly higher at 10°C than at 5°C for both species. The mean egg diameter correlated positively and significantly with female prosome length (PL) in each species. SEP of T. longicornis correlated negatively and significantly with PL. Daily EP and SEP were similar to rates recorded for other Acartia and Temora species in temperate and warm regions. The influence of environmental factors (temperature, salinity, and phytoplankton concentration) on EP of both species is discussed. We conclude that temperature is the main factor determining the reproduction rate and timing in A. longiremis and T. longicornis in the Barents Sea.","subitem_description_type":"Abstract"}]},"item_10001_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"小型カイアシ類は、北極海の食物連鎖において、一次生産者と高次捕食者を結ぶ重要な役割を果たしている。本研究では、夏季バレンツ海南部のDalnezelenetskaya Bayで普遍的に出現する２種のカイアシ類Acartia longiremisおよびTemora longicornisを用いて、実験条件下における雌1個体当たりの産卵速度（EP）および単位体重当たりの産卵速度（SEP）を見積もった。水温5-10℃におけるEP およびSEPは，A. longiremisではそれぞれ4.7±0.4 eggs female-1 day-1 、0.025±0.002 day-1、 T. longicornis ではそれぞれ 13.1±0.9 eggs female-1 day-1 and 0.075±0.006 day-1であった。10℃でのEPとSEPは、両種ともに5℃でのそれらより有意に高かった。平均卵径は，それぞれの種で前体部長（PL）と有為な正の相関を示した。一方、T. longicornis のSEPは、PLと負の相関を示した。本研究で得られたEPとSEPの値は，温帯海域に生息する他のAcartia属やTemora属で報告されている値と同程度であった。以上のことから，バレンツ海に生息するA. longiremisおよびT. longicornisの2種のカイアシ類の卵生産は，餌濃度よりもむしろ水温によって支配されていることが示唆された。","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立極地研究所"}]},"item_10001_relation_12":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"110009821843","subitem_relation_type_select":"NAID"}}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1016/j.polar.2014.04.001"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.1016/j.polar.2014.04.001","subitem_relation_type_select":"DOI"}}]},"item_10001_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12240481","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18739652","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Dvoretsky, Vladimir G."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Dvoretsky, Alexander G."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Dvoretsky, Vladimir G.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Dvoretsky, Alexander G.","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Egg production","subitem_subject_scheme":"Other"},{"subitem_subject":"Temora longicornis","subitem_subject_scheme":"Other"},{"subitem_subject":"Acartia longiremis","subitem_subject_scheme":"Other"},{"subitem_subject":"Coastal waters","subitem_subject_scheme":"Other"},{"subitem_subject":"Barents Sea","subitem_subject_scheme":"Other"},{"subitem_subject":"Egg production","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Temora longicornis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Acartia longiremis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Coastal waters","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Barents Sea","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"Egg production rates of two common copepods in the Barents Sea in summer","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Egg production rates of two common copepods in the Barents Sea in summer"},{"subitem_title":"Egg production rates of two common copepods in the Barents Sea in summer","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"27","path":["1332"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-10-14"},"publish_date":"2014-10-14","publish_status":"0","recid":"10036","relation_version_is_last":true,"title":["Egg production rates of two common copepods in the Barents Sea in summer"],"weko_creator_id":"27","weko_shared_id":27},"updated":"2023-07-25T16:22:13.701922+00:00"}
