Our correction is for figure 3 of the manuscript, which was missing elements that should have been included in the final version of the file. The former image also plotted data for an incorrect animal from our study. Changes to this figure do not impact any of the analyses, statistical calculations or conclusions of the paper.

Figure 3.

Localized breadth at localities with at least five individuals present. (a) The local breadth of a taxon site (the mean indicated by a grey circle) is typically a small fraction (less than 0.5) of its overall breadth. The insert (adapted from Bolnick et al. 2003 [34]) shows a conceptual depiction of how individual populations partition the overall niche breadth of a taxon. Most taxa in this study have ratios between 0.32 and 0.60, corresponding to conceptual depictions 2 or 3, where populations are different, but can overlap somewhat in their breadth. (b) Site specific values presented as boxplots for taxa illustrate the relatively narrower breadth at the local level and the distinctions between ‘populations’. Site names are indicated by marker shapes. The NALMA of a site is indicated by the shading of the bar. In this example, the average fraction of the total dietary breadth across sites for Equus (a highy hypsodont grazer; n = 138 across 13 localities) is less than Mylohyus (a brachydont browsing mixed-feeder; n = 33 across three localities), Platygonus (n = 42 across four localities) and Odocoileus (a brachydont browser; n = 43 across six localities).

The correct figure is below and this has been updated on the publisher's website.
