Resumen
Introducción: Los bosques amazónicos con diferentes grados de perturbación antrópica en proceso de regeneración natural albergan gran cantidad de especies de primates en simpatría. Sin embargo, aún es carente el estudio de su uso por primates. Objetivos: Estudiar la dinámica espacial y temporal dentro de la comunidad de primates en un bosque en regeneración en la Reserva de Biosfera del Manu. Métodos: Se analizaron dos sets de datos históricos de Crees Foundation for Manu que comprenden registros desde enero 2011 hasta febrero 2023 y corresponden a datos incidentales y transectos lineales terrestres en tres tipos de bosque con diferente grado de perturbación histórica. Resultados: Lagothrix lagothricha y Ateles chamek mostraron preferencia por bosques menos perturbados; Plecturocebus toppini, por bosques más perturbados; y las demás especies no mostraron una preferencia clara. En cuanto a la estratificación vertical, A. chamek, L. lagothricha y Alouatta sara mostraron preferencia por el estrato alto; P. toppini, Saimiri boliviensis y Sapajus macrocephalus mostraron preferencia por los estratos medio y alto, y Leontocebus weddelli y Aotus nigriceps, por el estrato medio. De acuerdo con la frecuencia horaria de cada especie se observó que siete especies (A. chamek, S. macrocephalus, S. boliviensis, P. toppini, L. lagothricha, Leontocebus weddelli y A. sara) fueron observadas durante el día, cuatro fueron similares. Conclusiones: En el estudio, la comunidad de primates cambió en el gradiente de perturbación debido a las preferencias de algunas especies. Los primates registrados hacen un uso diferenciado de los estratos verticales y la mayoría de ellos mostraron períodos de actividad diurnos.
