Conceptual SEM structure used to test for direct effects of tree characteristics and the environmental template on variations in canopy temperatures (Tvar) and the factors moderating transpirational performance of trees; Covvar = interspecific variation in canopy cover, Covmean = mean canopy cover, SFvar = interspecific variation in sap flow density, SFmean = mean sap flow density, Tamb = ambient temperature, wind = wind speed, soil = soil moisture, radiation = total solar radiation.
