Taxonomic investigations on the epiphytic lichens on quercus sp. of Uludag (Bursa – Turkey)

Abstract

In this study, 85 lichen taxa belonging to 34 genera and 15 families were determined from 772 lichen samples collected from 30 stations from 06.06.2004 to 24.05.2006. Seven lichen taxa for Bursa are new records. The epiphytic lichen taxa are collected from Quercus cerris L. var. cerris, Quercus frainetto Ten., Quercus infectoria Oliver subsp. infectoria, Quercus petraea (Mattuschka) Liebl. subsp. iberica, Quercus petraea (Mattuschka) Liebl. subsp. petraea, Quercus pubescens Willd. and Quercus robur L. subsp. robur L. which spread all over Uludag. The aims of this study is to investigate the epiphytic lichen diversity based on their substrate specificity that are grown on the Quercus species in Uludag mountain. The different epiphytic lichen species from different Quercus taxa at the same locality or same substrat at the different locality were determined. From these results, we think that the various properties of substrats change at the different levels because of the environment factors and this changing is effected the diversity and composition of the epiphytic lichen species on Quercus taxa.
