INVITED SPEECH THE CHALLENGE OF SAVING URSUS ARCTOS MARSICANUS
about 100 km east of Rome, a small population of Abruzzo brown bear (Ursus arctos marsicanus) is still present. It has been separated from the Alpine population for at least 4-600 years and it shares a unique mtDNA haplotype. Its extent of occurrence is estimated to be 1,500 – 2,500 km 2 with occasi...
