In addition to their low rates of growth and reproduction, orangutans live solitary lifestyles, avoiding the increased foraging costs incurred in large groups, and use locomotor strategies that minimize the cost of travel through the canopy.
“In addition to their low rates of growth and reproduction (8), orangutans live solitary lifestyles, avoiding the increased foraging costs incurred in large groups (8, 28), and use locomotor strategies that minimize the cost of travel through the canopy (29).”

Observations in the wild support the hypothesis that ecological food constraints have had widespread repercussions on the physiology, behavior, and life history of orangutans.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
