Abstract
with widespread high-quality fallback foods at the Tuanan site, and 2) long periods of extreme fruit scarcity with occasional supra-annual masts at the Wehea site.I show that female orangutans living in these two habitats exhibit different responses to scarcity: females at Tuanan engage in diet switching and shrink their home ranges, whereas females at Wehea move over long distances, likely area-switching.I conclude that female orangutans at Wehea employ this ranging response because of the duration and severity of resource scarcity at this site, and that this response may be facilitated by the fine spatial grain of the habitat and their propensity for energetically low-cost ground travel, and further enabled by the low population density which allows for females to move unimpeded through the habitat without risk of agonistic encounters.At Tuanan, on the other hand, the existence of decentquality ubiquitous fallback foods enables diet-switching, while the high population density may increase the risk of social aggression that wide-ranging females would incur, thus further discouraging area-switching in response to scarcity.These results provide a better understanding of several of the factors affecting movement and space-use among orangutans.In particular, my results increase our understanding of the conditions that favor a ranging versus a dietary response to scarcity of preferred foods, and show how population density may influence female orangutan ranging patterns and transgenerational site-fidelity.These results have important implications for orangutan conservation, and should be considered when designing and implementing landscape planning and translocation initiatives.

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.
