This study incorporated the Penrose distance statistic, multivariate statistics, carnivore sighting data, and land cover data within a GIS to create habitat models for sympatric red foxes, coyotes, and bobcats in southern Illinois. Habitat variables were quantified for 1-km2 buffered areas around carnivore sighting locations. Only one variable differed between coyote-red fox and coyote-bobcat pairings, demonstrating significant overlap in these two species-groups. However, five variables differed between red foxes and bobcats, indicating considerable differences in habitat affiliation between these species. Model validation by independent sighting locations determined model fit was good, with 64% and 65% of the validation points for red foxes and bobcats, respectively, falling within the top 50% of Penrose distance values. Red foxes were affiliated with mixtures of agriculture and grassland cover, while bobcats were associated with a combination of grassland, wetland, and forest cover. This study provides insight into habitat partitioning and overlap among sympatric carnivores.REFERENCES Analytical Software, Inc. 2003. STATISTIX 8.1. usera#39;s manual. ...
