The influence of climate and the presence of predators on the daily activity pattern of collared peccaries ( Dicotyles tajacu, Cetartiodactyla)
Abstract Collared peccaries ( Dicotyles tajacu , Cetartiodactyla) adjust their daily activity patterns in response to different factors, such as the presence of predators or climatic factors (temperature and rainfall), as a way of ensuring survival. The knowledge of these patterns allows us to under...

A low level of overlap was recorded with the activity of Puma concolor and high level of overlap with the activity of Leopardus pardalis , Canis lupus familiaris , and human activity. The low activity overlap of collared peccaries with P. concolor may be related to an attempt to decrease predation risk, while the high activity overlaps with domestic dogs and humans may be related to the low hunting pressure exerted in the region and also to the foraging opportunities for peccaries in areas closer to human settlements, where orchards are present. The high activity overlap with L. pardalis can be related to the smaller size of this predator and the aggressive group anti‐predator behaviour of the collared peccary. Our results show that collared peccaries can adjust their daily activity when an apex predator is present, but this adjustment is not generalized to all predators.
