Abstract: Comparative dendrochronological analysis of red spruce from Central PEI and Southwestern NS
Bibliographic record
Abstract
Two stands of red spruce were sampled and analyzed using standard dendrochronological research techniques. One stand from Fort Augustus, Prince Edward Island and one stand from Harmony Lake, Nova Scotia were assessed using similar methods to test for similarities and differences between the two locations. The growth characteristics were found to be very similar at the two locations except during the years 1974 to1989. The two chronologies revealed that the stand at Fort Augustus experienced a sudden growth decline over this period. A climatological analysis indicates that long-term records show strong similarities over the period in question for both precipitation and temperature patterns. Therefore, the difference in radialgrowth trends is likely due to an internal forcing factor such as the effects of a budworm outbreak in the Fort Augustus region. Aside from the fi fteen-year period when the Prince Edward Island stand was experiencing a growth decline, the radialgrowth patterns of the two sites are strongly correlated and suggest the presence of similar environmental conditions. This is important for further dendrochronological investigations as it indicates that strong spatial similarities can be found at locations at least 280 km apart within the Maritimes.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
