The succession of epiphytic bryophytes was investigated in Cedrus libani . forest on the Meydan Plateau (Aladağ). A total of 19 taxa (16 mosses, 3 liverworts) were recorded in 90 sampling relevés, 4 dm2 each. Index of ecological significance (IES) was used to evaluate the ecological importance of the taxa in epiphytic habitats on tree trunks. | Turkish Journal of Botany Research Article Turk J Bot (2013) 37: 389-397 © TÜBİTAK doi: Succession of epiphytic bryophytes in Cedrus libani forest on the Meydan Plateau (Aladağ) Tülay EZER*, Recep KARA Biology Department, Faculty of Science, Niğde University, 51100 Niğde, Turkey Received: Accepted: Published Online: Printed: Abstract: The succession of epiphytic bryophytes was investigated in Cedrus libani . forest on the Meydan Plateau (Aladağ). A total of 19 taxa (16 mosses, 3 liverworts) were recorded in 90 sampling relevés, 4 dm2 each. Index of ecological significance (IES) was used to evaluate the ecological importance of the taxa in epiphytic habitats on tree trunks. Additionally, the epiphytic bryophyte succession of the cedar forest was analysed using multivariate classification techniques (TWINSPAN and DECORANA). The multivariate analysis results showed that the epiphytic bryophyte communities were divided into 2 main groups and 5 different subgroups associated with successional gradient. Moreover, habitat affinities of the taxa and their life forms were evaluated along a gradient of height and the gradient of age of the host tree. Tortella tortuosa, Syntrichia ruraliformis, and Bryum capillare were only found on young trees, Zygodon rupestris only on middle-aged trees, and Pterigynandrum filiforme on aged trees.

Introduction Turkey is geographically located on the border between Europe and Asia and, as a result, it contains diverse habitats and ecosystems. Phytogeographically, it is composed of 3 regions: the Euro-Siberian region, the Irano-Turanian region, and the Mediterranean region, which forms the southern part of Turkey. These phytogeographical regions have provided Turkey with rich floral diversity. The eastern Mediterranean region contains a
