Bibliographic record
Abstract
The aim of this study was to determine the population structure of Pachycereus weberi in Canada del Zopilote (Buzzard Canyon), Guerrero, Mexico. An observation plot of 50 x 50 m (2,500 m²) was established and divided into quadrats of 10 x 10 m to facilitate the field survey. All P. weberi individuals with height ≥ 0.10 m were tagged, and their total height, diameter at breast height (dbh), and location by X and Y coordinates were recorded. In addition, all individuals of associated woody species with dbh ≥ 5 cm were tagged, identified and their diameter and coordinates within the plot recorded. We calculated the spatial distribution and correlation patterns of the P. weberi population divided into two developmental stages, juveniles and adults, using Ripley’s index. A total of 18 species associated with P. weberi were recorded. P. weberi attained the highest Index of Relative Importance Value with 41.1 %, followed by Acacia tenciifolia with 22.6 %. P. weberi individuals with total height greater than 8.5 m and diameters from 5 to 43.8 cm were recorded. The spatial distribution pattern was clumped for individuals in both juvenile and adult development stages. The spatial correlation showed a repulsion pattern at distances of 2 to 13 m between juvenile and adult P. weberi. The diameter distribution suggests an episodic recruitment behavior, with low recruitment rates in intermediate diameter classes between juveniles and adults. PALABRAS CLAVE: Pachycereus weberi, Indice de Ripley, indice de valor de importancia relativa, patron de distribucion espacial, patron de correlacion espacial

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; both teacher heads agree on what is shown here.
