Bear footprints and their use for monitoring and estimating numbers of brown bears (Ursus arctos L.) in Bulgaria

We present an improved table of the footprint dimensions of the Bulgarian/ Eastern European brown bear (Ursus arctos L.). Our results demonstrated congruence between the length of the hind paw footprint and the width of the fore one, as well as correlation between footprint size, age, and sex of the...
