Relative variable contribution to distribution models with vegetation parameters removed.

Relative contribution of variables to models with no vegetation predictors. See online supporting materials for explanation of variables. Only variables with a relative contribution of 15% to at least one haplotype are included. Although the variables which contribute most to each model change slightly with the inclusion of vegetation, haplotype KK5 remains determined primarily by temperature factors, while KK15 is driven most by precipitation. See text for details.
