沿着重金属污染梯度比较了蓝宝石和山雀雏鸟和成鸟的重金属水平、钙水平、繁殖参数和繁殖条件。这两个物种开始奠定了较早，并表现出较差的雏鸟生长和较小的羽化概率在污染区，这是在春季由于稀疏的森林物候先进。主要的种间差异的反应是，窝卵数和孵化成功率下降，在污染区的R major，但没有在C caeruleus。两种鸟类雏鸟粪便中的重金属含量比较相似，但蓝胸蛙的Ni和Pb含量高于大胸蛙。然而，后一种物种表现出显着较高的粪便钙浓度。较低的钙水平和较高水平的一些重金属在C caeruleus表明，在钙缺乏的环境中，这个物种可能更容易受到负面污染的影响比P。(C)2009爱思唯尔有限公司保留所有权利。
We compared heavy metal levels, calcium levels, breeding parameters and condition of nestling and adult Cyanistes caeruleus and Parus major along a heavy metal pollution gradient. Both species started laying earlier and showed inferior nestling growth and smaller fledging probability in the polluted areas, which are phenologically advanced in spring due to sparse forests. The major inter-specific difference in the responses was that the clutch size and hatching success were decreased in the polluted area in R major, but not in C caeruleus. Heavy metal profiles in nestling feces were relatively similar in the two species, though Ni and Pb levels were higher in C caeruleus than in P. major. However, the latter species showed markedly higher fecal calcium concentrations. Lower calcium levels and higher levels of some heavy metals in C caeruleus suggest that in Ca-deficient environments this species might be more susceptible to negative pollution effects than P. major.
