연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Abstract AI-Helper 아이콘AI-Helper

Dietary lipid biomarkers (fatty acids, fatty alcohols, and sterols) in adult specimens were analyzed to compare and understand the feeding ecology of the euphausiid, Euphausia pacifica, from three geographically and environmentally diverse Korean waters (Yellow Sea, East China Sea, and East Sea). To...

  • 1999) 등에서 지방의 중요성에 관한 많은 연구가 수행되어 왔지만, 지방먹이추적자를 활용한 한국 근해 크릴의 섭식생태 연구는 아직 시도된 바가 없다. 따라서, 본 연구에서는 한국 근해의 E. pacifica의 지방 함량 및 구성에 관한 기본 정보를 제공하고, 지방 구성 성분을 통해 한국 근해의 E. pacifica의 섭식생태를 이해하고자 한다.

질의응답

핵심어 질문 논문에서 추출한 답변
지방은 어떻게 나누어 지는가? 1999). 이와 더불어, 지방은 모든 생물체의 필수 생화학적 구성 요소로서, 크게 극성지방(예 phospholipids, glycosylglycerides)과 비극성 지방(예 acylglycerols, sterols, free fatty acids, wax, steryl esters)으로 나누어진다. 극성지방과 스테롤은 세포막을 구성하는 주요 성분으로 세포막의 구조와 기능에 중요한 역할을 한다.
크릴이 이용하는 먹이원에는 무엇이 있는가? 2001). 실제로, 남빙해의 Euphausia superba는 극한 환경에서의 생존을 위하여 계절 및 서식 환경에 따라 해빙 생물상(Stretch et al. 1988; Daly 1990), 동물플랑크톤(Hopkins et al. 1993; Huntley et al. 1994), 유기 쇄설물(Kawaguchi et al. 1986) 등 다양한 종류의 먹이원을 이용하고 있다. 또한, 북동 일본 연안에서 E.
Euphausia pacifica의 서식지는 어디인가? 난바다곤쟁이류(이하 ‘크릴’)중, Euphausia pacifica는 한국 근해를 포함하는 북태평양의 넓은 해역에 걸쳐 서식하고 있으며, 해양 생태계에서 일차생산자(식물플랑크톤)와 상위포식자 사이를 연결하는 핵심적인 역할을 하는 것으로 알려져 있다(Mauchline and Fisher 1969; Mauchline 1980). 황해에서는 연중 출현하는 동물플랑크톤 중 단일종으로는 가장 많은 생체량을 차지하고 있어서 어류(멸치, 정어리 등)를 비롯한 상위포식자의 주요 먹이원으로 이용되고 있다(Huang 1986; Zhu and Iverson 1990).
