Abstract

The aim of this study was to compare ecophysiological basis for developing feral pigeons (Columba livia f. urbana) in various environments of Northern Poland. We examined heavy metals contents, lipid and protein peroxidation, antioxidant enzymes activity in individuals growing and feeding in the different polluted regions. Pigeons from urban area possessed high maintenance of cadmium in the blood, but low lead in comparison to birds from rural area. Our results suggest that increased level of heavy metals (Pb and Cd) in the blood of pigeons from different regions of Northern Poland tended to affect negatively initiate lipid peroxidation and increased oxidative modified protein content. Our results suggest that increased level of oxidative stress in birds is dependent upon environmental pollution. Statistical analysis (ANOVA and GLM) has shown that colony localization (urban or rural areas) modified antioxidative defense system, level of lipid and protein peroxidation, and blood total antioxidant activity.


Key words: feral pigeon, Columba livia, lipid peroxidation, oxidative stress, antioxidative enzymes, environment, toxic heavy metals
