Abstract

fetched live from OpenAlex

Conservation budgets are limited, so it is important to prioritize actions to efficiently protect species.Proxies for cost are frequently used as estimates for inclusion in prioritization problems to make more effective decisions.In this research, we combine real-world cost data for private land and species habitat models into a spatial prioritization problem to explore cost-efficient habitat protection possibilities for species at risk in Ontario.Our findings suggest that protecting species at risk through land purchase may be most cost efficient in areas where species-at-risk richness is relatively high and population density is low, such as in central Ontario.However, the budget required to adequately protect species at risk through land purchase is much larger than is currently available for conservation efforts.Therefore, to effectively protect species at risk in Ontario, we recommend the use of alternative conservation measures, such as easements on private land, to supplement already protected areas.

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.
