“Dear Enemies”, “Nasty Neighbors”, and the Strength in Numbers
Loud calls are critical for primate intergroup communication, influencing resource defense, territorial boundaries, and conflict management. This study examined the interplay of familiarity and numeric odds in shaping the behavioral and hormonal responses of male mantled howler monkeys ( Alouatta palliata ) to simulated intruder calls. Using playback experiments, we tested whether responses were consistent with “dear enemy” dynamics, which predic…
Noise intensity modulates the responses of mantled howler monkeys to anthropophony
Anthropogenic noise is a major global pollutant but its effects on primates are poorly understood, limiting our ability to develop mitigation actions that favor their welfare and conservation. In this study, we used an experimental approach to determine the impact of variation in noise intensity on mantled howler monkeys ( Alouatta palliata ). We conducted the study at Los Tuxtlas (México), where we studied the physiological stress (proxied via f…
Female reproductive energetics in mantled howler monkeys ( Alouatta palliata )
OBJECTIVE: Reproduction entails several challenges to primate females, among which energetic costs are remarkable at certain stages of the reproductive cycle. Still, females may use behavioral and physiological strategies to cope with those challenges. We had previously reported covariation between female energetic condition through the reproductive cycle and time-budget adjustments in mantled howler monkeys (Alouatta palliata). Accordingly, we s…
