Resumen
Los perros domésticos son una amenaza para la biodiversidad. Evaluamos los patrones de actividad de los perros domésticos y mamíferos terrestres en un parche de bosque atlántico en el noreste de Brasil. Esperábamos que los mamíferos nativos cambiaran su patrón temporal de actividad en presencia de perros domésticos. Instalamos 16 cámaras trampa en 2019 (enero-marzo) y 16 cámaras en 2021 (febrero-abril), com un esfuerzo de esfuerzo total de 640 días-trampa. Clasificamos la actividad de las especies como diurnos, catemerales, nocturnos y crepusculares. Encontramos 274 registros de 11 especies de mamíferos y solapamiento de actividad entre perros domésticos y mamíferos terrestres. Los coatíes y los agutíes fueron estrictamente diurnos en ambos años, mientras que los perros domésticos presentaron un patrón de actividad catemanal en 2021. Los agutíes y los perros domésticos presentaron un patrón uniforme, pero no así los coatíes. Aunque nuestros hallazgos sugieren una influencia limitada de los perros domésticos sobre los mamíferos terrestres, deben implementarse programas de vacunación o esterilización para evitar un aumento del impacto negativo los perros sobre la fauna nativa.
