21. Distribution: Ursus arctos is the most widespread of bear species, ranging from northern Arctic to dry desert habitats throughout the northern hemisphere. Servheen (1990) estimated that by 1989, the species ’ range and numbers worldwide had been reduced by more than 50 % since the mid-I 800s and...
