Abstract
El proceso de urbanización es actualmente una de las amenazas más importantes que afectan a la biodiversidad, provocando una transformación de las áreas rurales y naturales hacia áreas urbanas. En este contexto, el objetivo de este estudio es evaluar la respuesta del comportamiento de los meso-mamíferos nativos frente a la urbanización en el Gran Concepción. Para ello, se examinaron y compararon los patrones de actividad de meso-mamíferos nativos, entre ambientes periurbanos y naturales. Se utilizaron datos de dos iniciativas de monitoreo. La primera, corresponde a un monitoreo anual que realiza la CONAF, con la instalación de 51 cámaras trampa en el Parque Nacional Nonguén. La segunda iniciativa, corresponde a un proyecto de ciencias ciudadana, por la fundación Pewma, donde se instalaron 18 cámaras trampa en el área periurbana de Concepción. Se encontró la presencia de Leopardus guigna, Lycalopex culpaeus, Pudu puda y Galictis cuja. En relación con la superposición temporal, no hubo diferencias significativas de los patrones de actividad entre área natural y periurbana. Es importante que se informe a la comunidad los resultados de este estudio, para visibilizar la importancia ecológica que tienen las especies, por ejemplo, las interacciones con especies invasora, la respuesta a la disponibilidad de recursos y factores antrópicos que alteran su hábitat, con el fin de promover la coexistencia entre humanos y animales.
