Experimental Study of Black Bear (Ursus americanus) and Grizzly Bear (U. arctos) Tooth Marks and Other Gnawing Damage on Bone

Forensic Anthropology, 2021
Tooth mark and other gnawing damage modifications on bone from African carnivores have been extensively examined, but there are less data on North American carnivores, especially on Ursidae (bears). The present study examined gnawing damage by captive black bear (Ursus americanus) and grizzly bear (U.

New insights into dietary management of polar bears (Ursus maritimus) and brown bears (U. arctos)

Zoo Biology, 2021
AbstractAlthough polar bears (Ursus maritimus) and brown bears (U. arctos) have been exhibited in zoological gardens for centuries, little is known about their nutritional needs. Multiple recent studies on both wild and captive polar bears and brown bears have found that they voluntarily select dietary macronutrient proportions resulting in much lower ...

Kraniometrijska analiza i spolni dimorfizam u smeđeg medvjeda (Ursus arctos, L.) u Hrvatskoj

2008
Porodica medvjeda (Ursidae) je sklona promjeni pojedinih svojstava pod utjecajem okoliša i načina prehrane. Cilj ovog rada je napraviti kraniometrijsku analizu populacije smeđeg medvjeda (Ursus arctos, L.) u Hrvatskoj kako bi se odredile kraniometrijske karakteristike populacije te utvrdile razlike u spolovima.

Genetičke osobitosti populacije smeđeg medvjeda (Ursus arctos) u Hrvatskoj

2009
Populacija smeđih medvjeda (Ursus arctos) u Hrvatskoj je najzapadnija stabilna, a ujedno i autohtona populacija medvjeda u Europi, što joj daje izuzetan značaj za očuvanje vrste na europskim prostorima. Gospodarenje populacijom smeđeg medvjeda zahtjeva poznavanje njezine genetičke raznolikosti, što dosad nije istraženo.
