The pesticide in brown hare adipose tissue as consequence of anthropogenic factors.

Abstract

The impact of pesticides on brown hare population in agro biotope under intensive conditions of agricultural production was analysed in this review paper. The use of pesticides represents one of anthropogenic impacts which if not applied in an adequate way may have drastic negative consequences when it reaches animal food chain. The most often visible examples of inadequate application of pesticides can be seen in mass poisoning when both herbivore and carnivore species fed on their residues perish. In the same way, another significant problem which is not easily visible are low doses of pesticides which can be found in brown hare tissue and which can, in the long run, lead to decrease in brown hare density but without visible mass deaths what most often causes a decrease in reproductive potential in conjunction with other natural and anthropogenic factors.
