Correlations between environmental variables used in the CVA analysis and the first two taxon ordination axes.

Bio6  =  minimum temperature of the coldest month; Bio12  =  annual precipitation; Bio15  =  rainfall seasonality (coefficient of variation); Green-up  =  day of the year of the onset of green-up; QScatMean  =  surface moisture (QSCAT); QScatsd  =  QSCAT standard deviation. See Table 1 and Materials and Methods for a full description of the environmental variables.
