Figure 8. Estimated native embolism across species and stands. Panel (a) is average estimated native embolism for each species at each stand. Groups of bars in panel (a) not sharing the same uppercase letters denote significant differences among species determined by a two-way ANOVA with species and age as fixed factors and region as a blocking factor (Table 4). Panel (b) is the relationship between average estimated native embolism and ΨLinterquartile range for each species at each stand. Solid line (Panel (b)) is best fit linear regression (least square means) across species. Error bars are the minimum and maximum estimated native embolism from 100 simulated data points calculated from the lowest 10% of ΨL from 50,000 bootstrapped samples for each species and each site (section 5.6).
