Social behaviours of captive <i>Trachypithecus cristatus</i> (Mammalia: Cercopithecidae) in the National Zoological Gardens of Sri Lanka
Bibliographic record
Abstract
Trachypithecus cristatus (Silvered Leaf Monkey or Silvered Lutung) occur on the Malay Peninsula, Sumatra, Borneo and nearby islands and live mainly in uni-male, female-bonded groups. This study presents preliminary data on social behaviours for Silvered Leaf Monkey in captivity. Behavioural observations were conducted on one group (one adult male, four adult females, three juvenile males and four juvenile females). Data were collected on 30 of the 60 calendar days at the National Zoological Gardens, Dehiwala, Sri Lanka. All behaviours including agonistic and dominance-related, locomotion, feeding and infant-related behaviours were included in the analysis. Unlike in wild populations, we found a clear dominance hierarchy among females. Key words: Trachypithecus cristatus; Captive Behaviour; Dominance; Hierarchy; Langur; Sri Lanka.DOI: 10.4038/tapro.v1i1.2781TAPROBANICA, April, 2009. Vol. 01, No. 01: pp. 66-73

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
