A left side bias was found for embraces in spider monkeys, while there was a trend toward a right bias in grooming. Lateralization patterns may be related to the difference in arousal implicated in risk (i.e., embraces) and routine (i.e., grooming) behaviors.

Circulating 25-OH-D in wild toque macaques averages three times the lower limit for human good health. Captive macaques on high vitamin D diets have circulating levels about twice the levels of these wild macaques, implying over supplementation.

We examined the effect of reproductive state on the foraging behaviors and social association patterns of female squirrel monkeys in an Amazonian rainforest, over 12 months.
