Figure 1

The distribution of co-occurring foods in polar bear scats collected from western Hudson Bay from 2006–2008 as an index of diet complexity. For each food item on the x-axis, each section of the vertical bars is the percent frequency of the number of co-occurring food items. For example, seed heads occurred alone in 39.5% of scats, with one other food item in 23.3% of scats, etc. The diamond points connected by the black line are the mean number of co-occurring foods (right y-axis) with associated standard errors for each food item.
