We measured the body composition, including bone mineral density (BMD) and food resource availability using dual energy X-ray absorptiometry and the carbon and nitrogen stable isotope ratios of body condition of 4 anuran species(Hyla japonica, Glandirana rugosa, Pelophylax nigromaculatus, Lithobates...

무미양서류를 채집할 때 방사선 조사와 안정동위원소 분석을 위해 각각 몇 개체를 사용하였는가? | 채집 개체 중 2차 성 분화가 진행되지 않은 미성숙 개체는 제외하였다. 방사선 조사와 안정동위원소 분석에는 청개구리와 옴개구리, 참개구리는 각각 8개체(암수 각 4개체)이며 황소개구리는 6개체(암수 각 3개체)를 사용 하였다. | |
방사선 촬영 기법을 사용하여 양서류의 무엇을 분석하였는가? | 본 연구에서는 방사선 촬영 기법을 사용하여 국내에 서식하는 무미양서류인 청개구리 (Hyla japonica), 옴개구리(Glandirana rugosa), 참개구리(Pelophylax nigromaculatus), 황소개구리(Lithobates catesbeianus)의 체성분과 골밀도를 분석하였다. 이중 엑스선 촬영 장치(Dual-energy X-ray absorptiometry)를 사용하여 체성분과 골밀도를 측정하였으며 암수 간 차이와 종 간 차이를 파악하였다. | |
방사선 촬영 기법을 사용한 신체 상태 평가 방법의 효용성을 확인하기 위해 무엇을 파악하였는가? | 이중 엑스선 촬영 장치(Dual-energy X-ray absorptiometry)를 사용하여 체성분과 골밀도를 측정하였으며 암수 간 차이와 종 간 차이를 파악하였다. 또한 방사선 촬영 기법을 사용한 신체 상태 평가 방법의 효용성을 확인하기 위해 무미양서류 4종의 먹이자원 가용성을 파악하고 신체상태와의 관계를 확인하였다. 신체를 구성하는 성분인 골, 지방, 제지방 비율과 골밀도는 암수 간 차이가 없었지만 무미양서류 4종 간 차이는 있었다. |
