Advances in field-based studies of primate behavioral endocrinology
Article Abstract:
Advances in field-based studies of primate behavioral endocrinology are presented, which shows that widespread application of noninvasive methods for measuring steroid levels in wild primates has revolutionized primate field studies in little more than a decade. This has made it possible for field workers to investigate questions about hormone-behavior relationships in ways that were previously feasible only in captive settings by noninvasive methods for obtaining primate endocrinological data.

Mechanical properties of foods used in experimental studies of primate masticatory function
Article Abstract:
A study was conducted to understand how jaw-muscle activity varies with food mechanical properties, as well as the toughness and elastic modulus of the majority of foods used in experimental studies of the nonhuman primate masticatory apparatus. It showed that food toughness ranges from approximately 56.97 Jm(super -2) (apple pulp) to 4355.45 Jm(super -2) (prune pit), while the elastic modulus of the experimental foods ranges from 0.07 MPa for gummy bears to 346 MPa for popcorn kernels.

Sexual communication between breeding male and female cotton-top tamarins (Saguinus oedipus), and its relationship to infant care
Article Abstract:
Male cotton-top tamarins are shown to be responsive to female scent cues of ovulation and are known to actively participate in infant care during the time when their mates are fertile. The results conclude that male cotton-top tamarins experience an increase in androgens that coincides with their mate's postpartum ovulation, which ensures optimal fertility.
