Siberian bear abnormal activity linked to parasite infection, expert says

The director of Baikal State Nature Reserve suggests that internal parasites, specifically helminths, may explain abnormal bear behavior observed in Siberia and the Far East since August. This is based on examinations of bears culled near Tankhoy, but the claim remains an expert hypothesis without broader corroboration. The development is notable for wildlife management and public safety, though its market impact is negligible.
