Relation between tree transpiration in invaded and uninvaded stands during the three hydrological years and resilience, resistance and recovery from extreme drought.
(a) Green, yellow and orange symbols represent tree transpiration (mm day−1) in the pre-drought, extreme drought and post-drought year. All regression lines were significant (p < 0.001 for all; r2adj of 0.97, 0.59, 0.86, for pre-drought, drought and post-drought years, respectively) and 95% confidence intervals are given (dotted lines) (b), Tree resilience, resistance (m3) and recovery (m3) after an extreme drought in trees in uninvaded and invaded stands. Tree resistance of zero represents the maximum resistance of trees to the extreme event. Different letters denotes differences at p < 0.05 between invaded and uninvaded stands (non-parametric Mann-Whitney U Tests, n = 4).
