Abstract

fetched live from OpenAlex

Models for fire interval distributions in ecological communities are proposed, based on an understanding of the processes that influence the probability of fire, especially changes to the amount and condition of the fuel. The models represent changes in the probability of fire as a function of time since last fire. Despite considerable differences in the probability distributions of fire intervals, the models generate very similar age distributions when the mean fire interval is the same. Therefore, fitting the theoretical distributions to observed landscape age structure is unlikely to allow discrimination between different models. Previously, the most commonly used models of fire intervals have been based on the Weibull probability distribution. We believe that this is unnecessarily restrictive, and a broader range of models should be considered. The models may be based on an a priori understanding of the ecosystem being studied. They should assist interpretation of observed or inferred fire interval distributions.

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.
