Abstract
The Arrayán tree (Calycolpus moritzianus) is an endemic species from northern South America and it is important for its potential in the medical and cosmetic industry. However, to take advantage of its applied potential different biological aspects, such as genetic diversity, must be characterized. We evaluated 5 RAMs markers on 45 individuals of C. moritzianus collected from 5 locations in Norte de Santander, Colombia, to estimate its genetic diversity. The clusteranalysis indicated heterogeneity between populations; however, Ocaña individuals were genetically more different, when compared with other populations. A multiple correspondence analysis revealed 2 population groups: the first one including individuals from Ocaña, and the second one that includes individuals from Salazar, Chinácota, Pamplonita and Toledo. This last group showed a higher degree of genetic diversity. We found an average heterozygosity (He) of 0.34 and a fixation index (FST) of 0.13 among populations. These results are likely due to the relatively high genetic distance, observed between Ocaña and the other populations, and because of the effect of geographical barriers in the area. This is the first study in population genetics of this important native timber resource in the northern Andes, and provides relevant information for future conservation strategies and its sustainable use.

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 it
