New ecological aspects of the pacarana (<i>Dinomys branickii</i>) in southeastern Peru
Bibliographic record
Abstract
Abstract This study provides new insights into the behavioral ecology of Dinomys branickii based on long-term camera trap surveys conducted at three sites along an altitudinal gradient in southeastern Peru. Notably, we document the first known cases of geophagy in this species, which suggests a highly herbivorous diet. Moreover, in contrast to previous reports that described D. branickii as a group-living species, our data indicate that it is primarily solitary, with group formations likely limited to reproductive activities. Additionally, we confirm the species’ predominantly nocturnal and crepuscular activity patterns, with most activity occurring between 02:00 and 05:00 h. By calculating and comparing camera trap detection rates, used as an index of relative abundance (RAI), for D. branickii across different surveys, we highlight the species’ ecological rarity, evidenced by consistently low detection rates (0.163; 0.173 and 0.011 events per 1,000 trap-days) across diverse habitats and survey designs.

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; a candidate call from one teacher head, not a consensus.
