title: Diversity in Shade and Light Leaf Morphology in Beech Populations of South Rodopi Mountains
abstract: Abstract The size and shape of tree leaves and their variation within the canopy are the result of both physiological plasticity and an overall adaptive strategy against unfavourable environmental conditions. In this study, diversity patterns at leaf morphological traits will be described within and among populations of trees with different phylogenetic background. Beech ( Fagus sp.) is a widespread tree in Eurasia, represented by two species; F. sylvatica in Europe and F . orientalis in eastern
