Abstract

fetched live from OpenAlex

Abstract: Animal ecology research could benefit from the measurement of individual morphological traits. In bovids, male horn size often correlates with annual reproductive success, is sensitive to resource abundance, and could be a predictor of survival. However, live captures are costly, involve some risk of injury or substantial disturbance to the animals, and are impossible in many situations. To remotely measure horn growth of free‐ranging Alpine ibex ( Capra ibex ), I designed an aluminum frame that holds parallel laser pointers and a digital camera. I took digital pictures of ibex horns and calculated horn growth based on the fixed distance between the 2 laser points. This simple and accurate technique could benefit many ecological studies that require linear measurements, such as shoulder height, body length, leg length, or fin length. It could also help measure body features (e.g., fur or skin patterns, scars), increasing the reliability of individual photographic identification.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

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.
