Ursus arctos, Alaska, brown bear, recreation, aircraft, land-use overlap, habitat fragmentation, and human disturbance




This thematic literature review presents a comprehensive analysis of the existing research on the various human disturbances that impact Alaskan brown bears (Ursus arctos). It meticulously explores key findings, trends, and gaps in the literature, focusing on the overarching themes of Land-Use Overlap, Hunting and Poaching, Noise Pollution, and Industrial Development. By synthesizing and critically evaluating a wide range of studies, this review aims to deepen our understanding of the common sources of disturbances and their implications on the spatial, feeding, and social behaviors of brown bears. A brown bear's response to human activities varies in intensity and is dependent on the type of disturbance(s) but generally brown bears will either flee from their location, change the time of their feeding patterns, relocate to an undisturbed area and/or continue with their daily activity patterns despite human presence. Future research on the relationship between humans and brown bears should look into the long-term impacts of habitat fragmentation and they may consider incorporating newer technologies into their methodology.
