Ezer, Tülay; Alataş, Mevlüt; Batan, Nevzat; Erata, Hüseyin
In this study, the epiphytic bryophyte succession of Picea orientalis forests on the Kümbet High Plateau (Giresun-Turkey) were studied. A total of 21 epiphytic bryophyte species were determined (16 mosses and 5 liverworts). The epiphytic bryophyte communities were sampled in 60 sample plots taken from the trunks of Picea orientalis, each of which was 20 × 20 cm in size. The Index of Ecological Significance (IES), based on a combination of the relative frequency and mean cover of epiphytic bryophytes, was used to evaluate the abundance of bryophyte communities in epiphytic habitats on the tree trunks. In addition, multivariate classification techniques (TWINSPAN and DECORANA) were used to classify the community structures in successional stages. TWINSPAN divided the 60 sample plots into two main groups: a) the lower base communities (LB) and b) the middleupper zone communities (MU). Moreover, the middle-upper zone communities (MU) were divided into two sub-groups associated with the successional gradient (MU1 and MU2). DECORANA classified these communities along the ordination axes 1 and 3 related to the height gradient of Picea orientalis and the moisture (from mesic to xeric) gradient of the epiphytic habitat. While Exsertotheca crispa, Cynodontium fallax, Lewinskya striata, and Habrodon perpusillus were only found on old spruce trees, Drepanium fastigiatum was only found on young trees and Lophocolea heterophylla was only found on middle-aged trees.

Aydinl, Sevinc; Alatas, Mevlut; Batan, Nevzat
In this study, DPPH and fatty acid contents were investigated of some taxa belonging to Neckeraceae (Alleniella complanata, Alleniella besseri, Exsertotheca crispa) and Hypnaceae (Hypnum cupressiforme, Hypnum resupinatum, Hypnum andoi) family collected from Kamilet Valley (Artvin-Arhavi) in 2017. DPPH free radical scavenging activity was determined according to the method developed by Brand-Williams et al. The fatty acids in extracts were analyzed via gas chromatography after transforming them into methyl esters. According to the obtained results, it was determined that the DPPH scavenging effects of taxa from Hypnaceae family were significantly higher than those of taxa from Neckeraceae family, and that the free radical scavenging effects of taxa from Hypnaceae family varied depending on the amount of extract. The saturated fatty acids content of the Neckeraceae and the unsaturated fatty acids of the Hypnaceae were found to be richer (p<0.001). The high DPPH activity in our study, especially in Hypnum species, suggested that Hypnum species were richer in terms of phenolic content. These compounds can be used in the pharmaceutical, cosmetic and food sectors, if both of these species are phenolic and fatty acid content can be obtained as pure.

U radu je prikazana lista vegetacijskih jedinica mahovina u Turskoj, radena prema metodologiji Braun-Blanquet- a. Ukupno je utvrdeno prisustvo 41 asocijacije i 19 subasocijacija, svrstanih u 19 sveza, 12 redova i 8 klasa. Štaviše, zabeleženo je i 6 zajednica i 17 jedinica nepoznatog fitocenološkog statusa. Briološke vegetacijske jedinice su prikazane u skladu sa njihovim akvatičnim, teresticnim i epifitskim karakterom, zajedno sa njihovim lokalitetima i sinonimima. © 2018 Institute of Botany and Botanical Garden Jevremovac, Belgrade.; A list of the known bryophyte syntaxa in Turkey compiled according to the methodology of Braun-Blanquet is presented in this study. Altogether, 41 associations and 19 subassociations belonging to 19 alliances, 12 orders, and eight bryosociological classes have been determined to date in Turkey. Moreover, six communities and 17 units of unknown phytosociological status have also been reported. The bryosociological syntaxa are grouped on the basis of their aquatic, terrestrial, or epiphytic character and given together with their localities and synonyms.
