Temporal variability of peak shoot mass of populations. A) Change of coefficient of variation (CV) of peak shoot mass with mean annual precipitation (MAP, thin lines) and with amplitude of daily mean rain (DMR, thick lines, 20% change of DMR scaled to 10 mm MAP). B) Absolute changes of CV expressed per absolute change of MAP (filled circles) or MAP-scaled change of DMR (outline circles). The arid region was excluded because most populations did not persist for the full simulation time (30 yr).
