I used trapping, track plates, and remote camera surveys to investigate a potential decline of gray foxes (Urocyon cinereoargenteus) in southern Illinois. Gray fox detection rates were low for all survey techniques when compared to more abundant mesocarnivore species. Home-range sizes were consistent with other studies, and the main source of mortality for foxes was coyote predation. To further understand gray fox ecology in Illinois, I assessed whether landscape patterns influence the relative abundance of gray foxes at the county scale. The standard deviation of the perimeter to area ratio of agricultural patches and the interspersion and juxtaposition index of grassland patches had the largest influence on gray fox relative abundance. Relative patch richness of the landscape and the coefficient of variation of the forest index had moderate influence on gray fox relative abundance. Future land use changes are likely to affect gray foxes, so cost-effective and accurate monitoring protocols are critical.Mammalian abundances on forest-farm edges versus forest interiors in southern Illinois: is there an edge effect. ...
