The effects of zoo visitors on a group of Western lowland gorillas <i>Gorilla gorilla gorilla</i> before and after the birth of an infant at Dublin Zoo
Bibliographic record
Abstract
Increasingly, it is understood that one must take into consideration all aspects of the zoo environment when assessing visitor effects. One of the unexplored topics in this area is the impact of a new group member in combination with the visitor effect on primates. Here, we investigate the effect visitors have on a group of Western lowland gorillas Gorilla gorilla gorilla before and after the birth of an infant. Observational data were obtained through scan sampling before and after the infant's birth and during different visitor conditions. Results indicate that the birth of the infant lessened some of the negative visitor effects previously observed in this group of gorillas. Particularly when in the ‘high’ visitor numbers category, the adult ♂ foraged more, was less inactive and more social after the infant's birth than he had been before. However, certain negative behaviours associated with increased visitor number, such as aggression and ‘back to viewing window’, were not diminished with the birth of the infant. Although results varied between individuals, there are indications that an event such as the birth of an infant may lessen negative visitor effects.

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.
