Summary of Results

The main aim of this pilot study was to examine the effect of trans-boundary air pollution from the nickel-smelters in Nickel on male reproductive health in birds. We planned to use the pied flycatcher (Ficedula hypoleuca) as a model species in our study, but due to the low number of individuals breeding in the area in 2012 and challenges obtaining pure ejaculates of that species, we switched to another passerine, the willow warbler (Phylloscopus trochilus). Male willow warblers were captured at three localities with increasing distances to Nickel and with different levels of contamination. We found significant variation among males in sperm quality, but no significant variation between the three sites. Hence, air pollution from Nickel does not seem to have any adverse effects on sperm quality in male willow warblers. However, we do stress that our sample size is low, and more data are required to make a firm conclusion.

Conclusions

A follow up study adding more data are required to be able to make a robust conclusion whether air-pollution from the Nickel smelters have a detrimental effect on the reproductive health of birds breeding in the Pasvik area.
