The occurrence of leucism in groups of tayras <i>Eira barbara</i> Linnaeus 1758 on the Guyana shield
Bibliographic record
Abstract
We report leucism in groups of up to five tayras, Eira barbara, in a fish-bone human settlement in southern Roraima, centre of the Guyana shield of the Brazilian Amazonia, during systematic line transect surveys in Terra Firme forests. These tayras had much larger non-rounded ears, and much larger and robust paws compared to current descriptions of the species. The leucistic individuals were snow-white with the exception of the distal half of the forearms, front paws, and the eyes, which were black. Leucism appeared to be commoner in this region than in the rest of the Guyana shield, as it occurred in a non-isolated population. The leucistic individuals did not appear to face the disadvantages reported in the literature, such as competitive exclusion, or difficulties in intra-specific communication and recognition.
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.
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.
