The model that best fitted the dataset proposed that the variation in specific leaf area affects photosynthetic rate and leaf nitrogen concentration, and this trait determines stomatal conductance, which also affects photosynthetic rate. • Shade conditions seemed to ameliorate, or at least not aggravate, the drought impact on oak seedlings, therefore, the drought response on leaf performance depended on the light environment.This study was supported by the grant FPI-MEC to J.L.Q. (BES-2003-1716), and by the coordinated Spanish CICYT project HETEROMED (REN2002-04041).Peer reviewedWiley-BlackwellMinisterio de Educación y Cultura (España)201220122006info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501http://hdl.handle.net/10261/47763reponame:DIGITAL.CSIC.
