| 摘 要： | 脂肪酸标记法是浮游动物食性研究的一种重要方法.将提取的脂质区分为中性脂和极性脂,可以进一步查明不同脂质在浮游动物食性研究中的作用.本研究通过分析不同脂质的脂肪酸构成,对2013年1月中国第29次南极考察期间在罗斯海采集的5种优势种桡足类的食性进行了研究.结果显示:5种桡足类的极性脂脂肪酸具有相似的组成,无法给出桡足类食... |

| Abstract: | Fatty acid is a marker of food composition in zooplankton diet analysis. Previous studies focused on using the total fatty acid of total lipids for food composition analysis. In this study, the extracted lipids were divided into neutral lipids (NL) and polar lipids (PL). We attempted to use the fatty acid information of classed lipids to identify the diet of five common copepod species in the Ross Sea, Antarctica, which are Calanoides acutus, Calanus propinquus, Metridia gerlachei, Oncaea curvata, and Paraeuchaeta antarctica. Our results revealed that the diet of five copepod species could be divided into three feeding habits. The copepods, C. acutus and C. propinquus, have a high fatty acid content of 20:1 + 22:1, indicating herbivorous feeding; M. gerlachei and O. curvata manifested omnivorous feeding; and C. propinquus are likely to be carnivorous because of the high 18:1n9 content. The fatty acids of PL among different species are also similar, while the fatty acids of NL are different, indicating that the diet information is mainly provided by the fatty acids of NL rather than PL. |
