The importance of regional dynamics in local populations of limber pine (<i>Pinus flexilis</i>)
Bibliographic record
Abstract
Limber pine (Pinus flexilis) populations in the Kananaskis Valley of Alberta have many of the traits of patchy metapopulations based on the reconstruction of the dynamics of 13 local populations. The populations exist in open canopied stands on high stress habitats of rocky ridges, scree slopes, and gravel creek beds. All populations showed continuous recruitment and low mortality. No population showed any evidence of local extinction as a result of negative population growth. Wildfire caused varied responses in the populations from extinction of the local populations to little or no effect. Populations extirpated by fire were quickly recolonized. Seed dispersed by the Clark’s nutcracker (Nucifraga columbiana) appears to be responsible for this rapid recolonization following wildfire. Limber pine does not persist in the seed bank for more than two years. Therefore, the limber pine populations are regionally persistent because rare extinction events (wildfire) are followed by prompt recolonization by seed dispersed by Clark’s nutcracker from other local populations.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
