(A) Standard ellipse areas of red fox (Vulpes vulpes) isotopic niche quantified by δ13C and δ15N at the population- (ellipse outlines) and individual- (filled ellipses) level during summer (green) and winter (blue) featuring four putative prey groups available to individuals (berries – red, small prey – dark grey, wolf carrion – light grey, and human foods – black). The associated box plots along the x- and y-axes show the differences between δ13C and δ15N across seasons. (B) Proportion of assimilated diets (of our prey groups Berries, Small Prey, Wolf Carrion, and Human Foods) of red foxes during summer (green) and winter (blue) from our informed mixing model.
