Abstract

fetched live from OpenAlex

In Focus: Blecha, K. A., Boone, R. B., & Alldredge, M. W. (2018). Hunger mediates apex predator's risk avoidance response in wildland-urban interface. Journal of Animal Ecology, 87, 609-622. https://doi.org/10.1111/1365-2656.12801 Puma (Puma concolor), an apex predator, can live at the edge of cities where pockets of low-density human dwellings form residential patches in the wildland-urban interface. Blecha, Boone, and Alldredge () tracked puma via global positioning system (GPS) telemetry collars to determine when and where they hunted and made kills. Well-fed puma (1-2 days between kills) strongly avoided residential patches despite these areas having higher mule deer (Odocoileus hemionus) densities and higher kill success for puma. However, the strong avoidance of residential patches completely disappeared as puma became hungrier (4-10 days since last kill) making it more likely that hungry individuals hunted in residential areas and ultimately increasing the likelihood of puma-human conflict.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
