^*Key to environmental variables: ELEV = elevation, DECMNT = December average daily minimum temperature, SPRFRST = date of first spring frost, FALLFRST = date of last autumn frost, ANNPRE = total annual precipitation, WINPRE = total precipitation from December through February, SUMPRE = total precipitation from June through August, JULARID = ratio of July precipitation to July average temperature plus 10.

^†Correlations equal to or greater than 0·25 are significantly different from zero at P = 0·05.

^‡Correlations equal to or greater than 0·19 are significantly different from zero at P = 0·05.

^§Correlations equal to or greater than 0·27 are significantly different from zero at P = 0·05.

^¶Correlations equal to or greater than 0·10 are significantly different from zero at P = 0·05.
