Figure S1. Hydraulic conductance of leaves (Kleaf) versus water potential trembling aspen seedlings grown at either ambient (AT; empty symbols and dashed line) or high temperatures (HT, AT +5°C; filled symbols and solid line). Different symbol shapes indicate different individual leaves. Vertical lines indicate midday leaf water potentials; arrows indicate leaf turgor loss points.
Table S1. The effect of rooting depth on aspen tree water use, gross primary productivity (GPP) and water use efficiency for trees grown under high temperatures (HT). Modeling outputs in Fig. 5 assumed that while HT doubled root biomass, a maximum rooting depth of 40 cm was achieved for both ambient and HT aspen (see Material and Methods). For the data in Supporting Information Table S1, we used measured HT root biomass, following an exponential decrease with soil depth (Schenk & Jackson 2002), consistent with the methods used to generate Fig. 5.
