Fig.Ā 4From: Extreme drought triggers parallel shifts in wood anatomical and physiological traits in upper treeline of the MediterraneanĀ AndesEstimated values of wood anatomical and physiological traits of K. angustifolia populations across drought periods (before megadroughtāBMd: 2000ā2007, megadrought periodāMd: 2010ā2018, hyperdrought periodāHd: 2019ā2020. A Ring width (RW,Ā mm yrā1); B vessel frequency (VF, ind mmā2); C hydraulic diameter (DH, Āµm); D vulnerability index of the xylem to embolism (VI); E potential hydraulic conductivity (Kp, kg m MPaā1Ā sā1); F wood intrinsic water-use efficiency (iWUE; Ī¼mol CO2 molā1 H2O). Differences between periods for each site were evaluated using Fisher's LSD test (pā<ā0.05)Back to article page
