Description Summary of climatic data for the 102 focal species with one or more non-native localities. Only the focal species (those for which rates are estimated) were screened for non-native localities. The number of unique native localities (after removing non-native localities) is shown, along with raw means for climatic variables (including all localities), recalculated means (after excluding non-native localities), and the difference between the raw and recalculated means. Boldfaced species are those in which the raw and recalculated means differ by >1°C for one or more temperature variables. Species with no data for recalculated means are those for which there were no native localities in the dataset of Edwards & Smith [13].

Description Results of tests of the relationship between species age and rates of niche change for each climatic variable (MAT = mean annual temperature, Bio1; TMAX = maximum temperature of the warmest month, Bio5; TMIN = minimum temperature of the coldest month, Bio6; MAP = mean annual precipitation, Bio12). Species ages and niche rates for all climatic variables initially failed the Shapiro-Wilk test for normality. Therefore results presented here are either ordinary-least squares (OLS) regressions after ln-transforming ages and nich rates, or (when one or both variables were still non-normal after ln-transformation), from a non-parametric test (Spearman’s rank correlation; SR). All OLS relationships are negative. Shapiro-Wilk test results are for the ln-transformed variables.

Description Summary of the impact of excluding species with one or more non-native localities on the difference in rates between past niche change among species and future climate change. Results shown are mean differences in rates among species for the intermediate model of future climate change, n is the number of species included in the comparison. “All species” are the original analyses, including species with some non-native localities. “Native only” indicates results after removing all species with any non-native localities. In the “Mostly native” comparisons, species with non-native localities were retained if they had similar mean values for climatic variables after the non-native localities were removed (i.e. all temperature variables differed by no more than 1°C when non-natives were removed).
