Abstract

fetched live from OpenAlex

Abstract 1. Stage‐specific survival and recruitment of spruce budworm were measured by frequent sampling of foliage in four outbreak populations over a 15‐year period in Ontario and Quebec, Canada. 2. Patterns of change in population density during the outbreak collapse phase were closely linked to changes in survival of the late immature stages, and were determined largely by the impact of natural enemies. 3. Host‐plant feedback also contributed significantly to survival patterns throughout the outbreak: annual defoliation influenced survival of fourth and fifth instars and fecundity while cumulative defoliation influenced survival of the very early larval stages (first and second) via impacts on stand condition. 4. Inclusion of this host‐plant feedback reveals spruce budworm population dynamics as a function of density‐related trophic interactions that vary in their order and strength of influence over time. This view re‐introduces the importance of forest interactions as a component of dynamics of the spruce budworm.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
