Análisis de la frecuencia de aparición en cámaras trampa del Oso andino (tremarctos ornatus) en diferentes épocas y microhábitats de la reserva el madrigal, zona de amortiguamiento del Parque Nacional Podocarpus

Abstract

The present work evaluated the difference in the frequency of occurrence in Andean Bear trap chambers in different microhabitats and seasons of the year. The field work was carried out between October 2013 and September 2014. The density of chambers was increased in an 11: 1 ratio in order to increase the success of recording activity in the microhabitats: montane forest, anthropic paramo, páramo shrub and herbaceous paramo. Each chamber was accompanied by odor attractants in order to increase detectability. In the results we obtained a total of 15 individuals, which would not have been possible without the densification of cameras. It was observed a preference of the bears by the forest and antropic páramo, also it was reported low frequencies within the shrub páramo and an apparent absence within the herbáceo páramo. It was evidenced a continuous use of the study area throughout the year by the species. We conclude that the results would be linked to the availability and diversity of resources within microhabitats and times of the year.
