| 摘 要： | 南极海豹是南极及南大洋的主要哺乳动物之一,它们在南极及南大洋生态系中占有重要地位,也是南极的主要生物资源之一。 关于南极海豹的数量分布、种群动态、生态习性以及它们之间的相互作用已有不少报导(陈万青,1973;宁修仁,1984;Bengtson, J. L.,Carrick, R.,1962;Erckson,A. W. , 1970,1971;和Davis, R. M. ,1970等)。现有的研究结果表明,在南极繁殖的真正海豹有四种,即锯齿海豹,又名食蟹海豹,其英文名为Crabeater Seal(Lobodon Carcino phagus),这是南极海豹中数量最多的一种,据估计有200—500万头,它们主要以南极磷虾而不是以蟹为食;威德尔海豹,其英文名为Weddell Seal(leptonychotes weddelli),这种海豹的数量占南极海豹第二位,估计有20—50万头;它们主要以乌贼和杜文鱼及磷虾为食;豹形海豹,其英文名为Leopard Seal(Hydrurga leptonyx);罗斯海豹,其英文名为Ross Seal(Ommatophoca ross Gray)。

| Abstract: | In present paper the analytical results on the components of protiens and amino acids in the liver, pancreas and stomach of Antarctic fur Seal i.e. Kerguelen fur seal (Arclocephalus gazalla) and Weddell seal (Leptongchotes Weddelli) are reported. It has been found that the contents of protiens in pancreas of two species of seals are high. 17 kinds of amino acids were found in the stomach of both these seals beside that tryptophane was hydradatezed, and glutamine and asparagine were transformed directly into aspartic and glutamic acids in the process of determination. Proline is absent in pancreas of Weddel seal. Methionine and proline have not been detected out in liver of both species. The absence Of these two kinds of amino acids in liver is surprising since our determination is made for general protiens. Methionine is also relatively low in pancreas and stomach of these two species. Moreover, the components of amino acides in liver, pancreas and stomach of both seals tend to be fairly similar, with highest contents of aspartic and glutamic acids and alanine, valine, leucine and lysine. The result is significant for study of polar biology. |
