Abstract
Several previous study results have already demonstrated that golden jackal and red fox may serve as biological indicators of trace elements and heavy metal concentrations in the various regions they inhabit. The aim of this study was to evaluate accumulation patterns of targeted elements (Al, Ca, Cr, Cu, Fe, Mg, Mn, Ni and Pb) in liver samples of red foxes and golden jackals collected during the same period in the southern part of Romania. The accumulation patterns of trace elements in the livers of sympatric golden jackal and red fox were practically the same. To date, separate studies of the species individually in different habitats have shown that either of the species can be used for ecotoxicological and biomonitoring studies. Moreover, in general gender related studies, no significant differences in the concentrations of the investigated elements were found in either jackals or foxes. Also, average metal concentrations in liver samples do not show significant differences between groups under and above 12 months of age.
