20.500.12556/RUL-166440 Human footprint and forest disturbance reduce space use of brown bears (Ursus arctos) across Europe Three-quarters of the planet's land surface has been altered by humans, with consequences for animal ecology, movements and related ecosystem functioning. Species often occupy wide geographical ranges with contrasting human disturbance and environmental conditions, yet, limited data availability across species' ranges has constrained our understanding of how human pressure and resource availability jointly shape intraspecific variation of animal space use. Leveraging a unique dataset of 758 annual GPS movement trajectories from 375 brown bears (Ursus arctos) across the species' range in Europe, we investigated the effects of human pressure (i.e., human footprint index), resource availability and predictability, forest cover and disturbance, and area-based conservation measures on brown bear space use. We quantified space use at different spatiotemporal scales during the growing season (May–September): home range size; representing general space requirements, 10-day long-distance displacement distances, and routine 1-day displacement distances. We found large intraspecific variation in brown bear space use across all scales, which was profoundly affected by human footprint index, vegetation productivity, and recent forest disturbances creating opportunity for resource pulses. Bears occupied smaller home ranges and moved less in more anthropized landscapes and in areas with higher resource availability and predictability. Forest disturbances reduced space use while contiguous forest cover promoted longer daily movements. The amount of strictly protected and roadless areas within bear home ranges was too small to affect space use. Anthropized landscapes may hinder the expansion of small and isolated populations, such as the Apennine and Pyrenean, and obstruct population connectivity, for example between the Dinaric Pindos population and the Alpine or Carpathian population. Our findings call for actions to maintain bear movements across landscapes with high human footprint, for example by maintaining forest integrity, to support viable bear populations and their ecosystem functions. anthropocene connectivity GPS telemetry human footprint intraspecific variation movement resource availability Ursus arctos antropocen povezljivost GPS telemetrija človeški odtis intraspecifične variacije gibanje razpoložljivost virov rjavi medved true false true Angleški jezik Slovenski jezik Članek v reviji 2025-01-13 10:50:20 2025-01-13 10:50:20 2025-07-29 14:49:52 0000-00-00 00:00:00 2025 0 0 18 str. iss. 1, art. e70011 Vol. 31 Jan. 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*15:599.744.211 1365-2486 10.1111/gcb.70011 221129731 Global_Change_Biology_-_2025_-_Hertel_-_Human_Footprint_and_Forest_Disturbance_Reduce_Space_Use_of_Brown_Bears__Ursus.pdf Global_Change_Biology_-_2025_-_Hertel_-_Human_Footprint_and_Forest_Disturbance_Reduce_Space_Use_of_Brown_Bears__Ursus.pdf 1 E5883D102976F483A21AD75EAD3ABAFA 46a4be12a80fd74119fd2ff99d01dcd6918319e6932d123403bcc1ec29caf300 54ea8e57-d4db-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=198338 https://onlinelibrary.wiley.com/doi/10.1111/gcb.70011 0 93dfa329-d193-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=198060 Biotehniška fakulteta 0 0 0
