Fig. 2: Allometry and climate affect required maximum whole-plant hydraulic conductivity.
From: Climate and hydraulic traits interact to set thresholds for liana viability
Required maximum whole-plant hydraulic conductivity (Kw,max(req)) as a function of diameter at breast height (DBH, A) and Huber value (sapwood area [cm2] per unit leaf area [m2]), B, C and hydroclimate (tropical moist forest or tropical dry forest). Total leaf area = 200 m2, 60% tree leaf area, 40% liana leaf area. In all three panels, colors represent the different hydroclimate scenarios (tropical dry forest = brown; tropical moist forest = blue). A Liana log(Kw,max(req)) as a function of liana DBH. B Liana log(Kw,max(req)) as a function of liana Huber value. C The ratio of liana Kw,max(req) to tree Kw,max(req) as a function of liana Huber value. Tree Kw,max(req) was computed at a reference scenario where tree DBH = 18.2 cm.
