Apennine brown bear (Ursus arctos marsicanus): does host population structure influence intestinal parasite community?
The present work was performed in order to assess the presence of parasites in the Apennine brown bear and to evaluate the relationship between parasites and an endangered host species. In our knowledge, the only parasitological survey about parasites in Apennine brown bear was performed between 199...
