Table 2. Principal Component Axes loadings showing variation in the habitat classes used in roadkill models and retained within the top subset of models (Δ AIC ≤ 2; see Supplementary Information for PCs 4-8).
The percentage of total variation explained by each component is given in parentheses. Loadings that explain the largest proportion of each PC are in bold.
