Life forms and life strategies of epiphytic bryophytes in Quercus vulcanica forests of Turkey
Kürschner, Harald; Parolly, Gerald; Erdağ, Adnan
A phytosociological analysis of the epiphytic bryophyte stands of the montane Quercus vulcanica forests of Turkey revealed a distinct community, the Orthotrichetum striati, which is reported for the first time from Turkey. It is frequently found on the tree trunks of this restricted Anatolian endemic oak species and its associates. Exclusive character species in Turkey is Orthotrichum striatum. Syntaxonomically higher-ranked character species, such as O. affine, O. lyelli and Leucodon sciuroides, allow a classification of the association within the Ulotion crispae alliance of the Orthotrichetalia order (holarctic Frullanio-Leucodontetea sciuroidis class). The life form and life strategy analyses show clearly that the assocation is mainly composed of perennial shuttle species and perennial stayers with a high asexual reproductive effort, reflecting the ecological key factors and the more or less stable climatic and site conditions.
