Copepod is one of the most widely distributed micro-crustaceans in the aquatic ecosystems. They are important components of zooplankton community and play an important role in the trophic dynamics as a good  biological indicator of production status. Therefore, understanding the processes that control the abundance and population dynamics of copepods is a major objective in aquatic ecology and limnology. \n    Calanoid copepod Eodiaptomus japonicus is an endemic species in Japan, and reported to be dominant species in the largest and oldest freshwater ecosystem — Lake Biwa. In this study, I studied the effect of temperature and food conditions on the life history traits of E. japonicus collected from the lake in the laboratory, to clarify responses of  somatic growth, reproduction and metabolic rates to the different temperature and food conditions, and consequently evaluated the impacts of eutrophication and global warming on its production during the last 4 decades in this lake. \n    The experimental studies for E. japonicus highlighted the importance of temperature and food conditions on its life cycle strategy. The results showed that this warm-adapted copepod was able to develop and reproduce in a wide range of temperature and food conditions, and the food effects depended on temperature. Somatic and population growths were depressed under food-limited condition especially at high temperatures due to lowering the net growth efficiency by high metabolic costs. Finally, the long-term analyses showed that production of the copepod tended to increase after 1990, and predicted that the warming would be  beneficial for E. japonicus population in the lake under current nutritional status, while disadvantageous under 6% lower food conditions assuming lowering the primary production due to global warming.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_1617186702042":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_1617265215918":{"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_1617604990215":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available"}],"filename":"24201k085_zenbun.pdf","format":"application/pdf","mimetype":"application/pdf","url":{"label":"全文","objectType":"fulltext","url":"https://usp.repo.nii.ac.jp/record/2000428/files/24201k085_zenbun.pdf"},"version_id":"63b89eeb-49d1-4cf4-8cad-0fe893b97e2b"},{"accessrole":"open_access","date":[{"dateType":"Available"}],"filename":"24201k085_yoshi.pdf","format":"application/pdf","mimetype":"application/pdf","url":{"label":"要旨","objectType":"summary","url":"https://usp.repo.nii.ac.jp/record/2000428/files/24201k085_yoshi.pdf"},"version_id":"a46cd807-7ab5-4b9b-b85b-436e4110cc71"}]},"item_1623818042585":{"attribute_name":"Identifier Registration","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24795/24201k085","subitem_identifier_reg_type":"JaLC"}]},"item_1719206165111":{"attribute_name":"学位名","attribute_value_mlt":[{"subitem_degreename":"博士（環境科学）","subitem_degreename_language":"ja"}]},"item_1719206202375":{"attribute_name":"学位授与機関","attribute_value_mlt":[{"subitem_degreegrantor":[{"subitem_degreegrantor_language":"ja","subitem_degreegrantor_name":"滋賀県立大学"}],"subitem_degreegrantor_identifie":[{"subitem_degreegrantor_identifier_name":"24201","subitem_degreegrantor_identifier_scheme":"kakenhi"}]}]},"item_1719206211735":{"attribute_name":"学位授与年月日","attribute_value_mlt":[{"subitem_dategranted":"2016-03-21"}]},"item_1719206220424":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第85号"}]},"item_1722321051957":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_1722583919300":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_title":"Physiological responses of a freshwater copepod Eodiaptomus japonicus on different temperature and food conditions, evaluating anthropogenic impacts in Lake Biwa","item_type_id":"40009","owner":"11","path":["1719211374765"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2016-11-18"},"publish_date":"2016-11-18","publish_status":"0","recid":"2000428","relation_version_is_last":true,"title":["Physiological responses of a freshwater copepod Eodiaptomus japonicus on different temperature and food conditions, evaluating anthropogenic impacts in Lake Biwa"],"weko_creator_id":"11","weko_shared_id":-1},"updated":"2024-08-29T23:15:38.411207+00:00"}
