Abstract

fetched live from OpenAlex

This study reports on the population structure and aboveground biomass of Avicennia marina to better understand the status of this tree species. In situ data include 20 random circular plots and measurements recorded from 2 216 individual trees. Direct measurements include tree status, stem number, diameter at breast height (DBH), and height; derived measurements include density, basal area, average crown spread, plot height, mortality rate, and aboveground biomass (AGB). The results show significant variations in density between the sampling plots, which have a total basal area of 20.58 m2 ha−1. Basal area mortality rate is very low (0.2 %), which indicates a healthy forest. The frequency distribution for tree height is positively skewed, meaning that these plots contain many small and few large trees. The distribution of DBH and average crown spread follows a reverse-J-shaped pattern, which is typical of naturally regenerating forests with a high population of seedlings and saplings. Finally, estimated ...

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.
