Activity patterns of jaguars and pumas and their relationship to those of their potential prey in the Brazilian Pantanal

摘要

Jaguar and puma are the largest cats in the American continent. Competition between both species is expected due to similarities in diet and habitat use. The objective of this study was to test whether temporal separation exists between these two species and to analyze whether their activity patterns coincide with those of some of their potential prey. We used data from camera trapping to estimate activity patterns and measure the overlap between activity distributions using kernel density. The activity of jaguars and pumas overlapped extensively and followed those of some of their potential prey, suggesting a potential for competition.
