| leaf traits and tree rings suggest different water-use and carbon assimilation strategies by two co-occurring quercus species in a mediterranean mixed-forest stand in tuscany, italy. | we compared the water-use characteristics of co-occurring mature quercus cerris l. and quercus pubescens willd. trees growing in resource-limited (mainly water) hilly habitats in tuscany, italy. the species differed in their distribution along soil water gradients and in their access to, and use of, water, even though the study year was wetter than average, though with a summer drought. compared with q. cerris, q. pubescens had greater access to soil water (less negative predawn water potentials ... | 2007 | 17938105 |
