摘要
Expanding knowledge on natural history of carnivores allows to understand mechanisms species developed for survival and improve decision-making aiming conservation. Studies on eco-morphological aspects of skunks, such Conepatus amazonicus , are scarce and usually based on small sampling size. We assessed roadkill individuals, camera trap records, and biometric data to describe the feeding ecology, activity period, and morphology of striped hog-nosed skunk in agroecosystems and protected areas in Central Brazil. Invertebrates represented critical items in the diet in agroecosystems, and due to an intermediate niche breadth (0.545), skunks could not be classified as specialists or generalists. Males and females have total niche overlap (0.94), and the diversity of items was not affected by proximity to urban centres. Animals develop their activities during the night, with 93
