Abstract

Questions: (1) Does shrub encroachment affect the regeneration of two contrasting species of oak along an elevation gradient in the west-central Iberian Peninsula? (2) Do different nurse shrubs have any relevant species-specific effects along the gradient? (3) Does shrub encroachment affect the location of the bioclimatic limit between these two oak species along the elevation gradient? Location: Twelve sites distributed from the Arribes del Duero plains to the Sistema Central mountains (Salamanca province, Spain). Methods: We measured the regeneration of two contrasting oak tree species (Quercus ilex subsp. ballota Samp - sclerophyllous, Q. pyrenaica Willd - marcescent) as the relative percentage cover of seedlings and saplings (
