From: Carrion from large carnivores and food from humans subsidize mesocarnivores year round

(A) Standardized proportion (and 95% confidence intervals) of assimilated resource subsidies from wolves (blue) and humans (green) in the diets of red foxes (Vulpes vulpes) based on our individual mixing models using whisker samples; above (A), we show the timing of Isle Royale National Park opening and closing to the public. (B) Foraging strategies of foxes quantified as similarity (s; x-axis) and specialization (µ; y-axis) when the park is open (green) and closed (blue) to visitors. The kernels shown are the 95% confidence kernels (transparent colors) ranging to the core kernels during each season. (C) Relationship between the proportion of wolf subsidies and human food subsidies in the diets of red foxes.
