The southern yellow-cheeked crested gibbon is an endangered species lives exclusively in undisturbed tropical forests and with highly frugivorous diet.
A significant seasonal shift in diet was observed; fruit generally dominated the diet in the rainy season and leaves in the dry season.
The activity budget and diet of the southern yellow-cheeked crested gibbon are associated with seasonal shifts in climate.
- Higher levels of submissive behaviors at the onset of the pairing process of rhesus macaques (Macaca mulatta) are associated with lower risk of wounding following introduction

Among rhesus macaques, higher levels of submissive behaviors expressed during the early phases of the introduction were associated with a decreased likelihood of wounding at later stages. Levels of affiliative behaviors have not added any power to the predictability of the statistical model. Exchanging submissive signals at the earliest stages of the introduction is critical in the determination of relative rank and preclude the need to establish dominance via aggression when allowed full contact.
- Personality assessment and model comparison with behavioral data: A statistical framework and empirical demonstration with bonobos (Pan paniscus)

Limitations in current statistical practice prevent primatologists from utilizing the full potential of their behavioral datasets for personality research. The present paper proposes an integrated statistical framework for assessing personality and comparing personality models across populations, species, and data collection methods. Applying this framework to observational data on bonobo (Pan paniscus) behavior suggests that personality variation across the measured traits is best described by two correlated but distinct Agreeableness and Openness dimensions.

- The relative effects of reproductive condition, stress, and seasonality on patterns of parasitism in wild female black howler monkeys (Alouatta pigra)

The relative effects of reproductive condition, stress, and seasonality on patterns of parasitism in wild female black howler monkeys (Alouatta pigra)
Rodolfo Martínez-Mota, Paul A. Garber, Rupert Palme, Thomas R. Gillespie
- Female howlers show similar infection rates across reproductive states.
- Glucocorticoid levels increase during pregnancy and during the first month of lactation.
- Glucocorticoids positively predict the probability of trematode infection.
