aLocational data: Alt, altitude
bClimatic data: P, annual precipitation; T, mean annual temperature; MTD, difference between the mean temperature of the warmest and coldest months; ATD, difference between the absolute maximum and minimum temperatures; SP, summer precipitation; Xi, xerothermic index [Xi = Σ(2Tm-Pm) if Pm < 2 Tm, or Xi = 0 if Pm > 2 Tm, where Tm is the monthly mean of the maximum and minimum temperatures (°C) and Pm is the monthly precipitation (mm)]
cTrial data: AG, annual growth experiment; DS, drought-stress experiment. Number of families and total number of individuals (in parentheses) per population
