Landscape use and food habits of the chilla fox ( Lycalopex griseus, Gray) and domestic dog ( Canis lupus familiaris) in a peri-urban environment of south-central Chile
Abstract Cities intensely modify natural environments and impose pressures on biodiversity. In this sense, carnivorous mammals are one of the groups most affected due to their food and space requirements. The feeding and spatial behavior of the chilla fox ( Lycalopex griseus , G., 1837) and dogs wer...
