Abstract

fetched live from OpenAlex

Roads in Southern Ontario have a detrimental effect on turtle populations. Due to complex habitat requirements and migratory movements, turtles are especially impacted by vehicular trauma. Past research indicates vehicular trauma is aggregated both spatially and temporally. For mitigation to be effective, it should focus on locations and times of concentrated trauma. This study used a geographic information system (ArcGIS) to map six years of turtle trauma data from the Ontario Turtle Conservation Centre, identify trauma clusters, and examine fine-scale landscape characteristics correlated with these clusters. Data for three turtle species (Emydoidea blandingii, Chrysemys picta marginata, and Chelydra serpentina) were combined with classified landscape imagery to analyze landscape pattern characteristics associated with trauma clusters by species, sex and season. By targeting locations with specific landscape characteristics and moments of peak potential, results can be used to guide species- and sex-specific mitigation efforts.

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.
