Variation of Fat and Protein Reserves in Wintering Dunlin, Calidris alpina
월동기 민물도요 Calidris alpina 의 지방과 단백질의 변화
Abstract
The changes of pectoral muscle size (as an index of protein reserves) and fat reserves (as an index of lipid) were measured in wintering Dunlin during 1988 -1989 on two estuaries located in the south coast of Korea. The mean of lean mass of February population was greater(11.8%) than that of October population. SMI of October population was greater(4.5%) than that of February population and lipid index of October population also greater(1.6%) than that of February population. This show that the body condition of October population is better than February population. The mean of fat and protein reserves of 22 % of Dunlin arriving on October for their wintering were higher than that of others, this group seems to continue their migration to south further and 11% of the wintering population seems to starve during winter.
