Entre galhos e estratégias: um estudo ecológico de Sapajus libidinosus na Universidade Federal de Goiás

Abstract

This study analyzed the behavior of Sapajus libidinosus in an anthropized environment at the Samambaia Campus of UFG, aiming to understand how ecological factors and human presence influence its social organization and feeding strategies. Observations were conducted using scan sampling, with records of age, sex, behaviors, and individuals' locations during morning and afternoon periods. Data were analyzed using R software, applying the daily median of unique individuals to estimate group size, avoiding overestimation due to repeated sightings. The proportions of adults, juveniles, and infants were also estimated. Results indicated that human presence affects feeding behavior and space use among the primates, demonstrating their ability to adapt to urbanized environments. Flexibility in social and feeding strategies was observed, highlighting the species’ high resilience, but also revealing risks associated with constant anthropic interference. It is concluded that the behavior of S. libidinosus is strongly shaped by ecological and social factors, and understanding these interactions is essential for guiding conservation efforts that balance biodiversity protection with the responsible management of shared environments between humans and primates.
