摘要
We investigated the levels of nickel in the feathers of the Western Reef Heron (Egretta gularis) and Siberian Gull (Larus heuglini) from the Hara Biosphere Reserve in southern Iran from November to December 2010. Analysis of variance shows that no significant differences in nickel levels were found between gender and age groups in either species, but it should be pointed out that the number of samples was small. Student t tests show that the amount of nickel in the feathers of the Siberian Gull was higher than in the Western Reef Heron. The level of nickel concentration in the Western Reef Heron was higher in females than in males; on the other hand, this level of concentration in the Siberian Gull was higher in males.
2010年11–12月,我们在伊朗南部Hara生物圈保护区调查并分析了黄喉岩鹭(Egretta gularis)和灰林银鸥(Larus heuglini)羽毛中的镍含量。根据方差分析,同一鸟种羽毛中镍含量在不同性别和年龄组之间均无显著差异,但这一结果的有效性受到本研究样本较小的影响。Student t检测结果表明灰林银鸥羽毛中镍含量高于黄喉岩鹭。雌性黄喉岩鹭羽毛中镍含量高于雄性,而雄性灰林银鸥羽毛中镍含量则高于雌性。
