摘要: Abstract Few researchers have developed large-scale habitat models for sympatric carnivore species. We created red foxes ( Vulpes vulpes ), coyotes Canis latrans ) and bobcats Lynx rufus in southern Illinois, USA, using the Penrose distance statistic, remotely sensed landscape data, sighting location data within a GIS. Our objectives were to quantify spatially model potential differences among Habitat variables quantified 1-km 2 buffered areas around mesocarnivore locations. Following variable reduction procedures, five (percentage of grassland patches, interspersion–juxtaposition forest mean fractal dimension wetland patches landscape, road density) used analysis. Only one differed P
