Epiphytic bryophyte vegetation of the Samanli Mountains (Sakarya-Kocaeli-Yalova-Bursa) in Northwest Turkey; [Epifitska vegetacija mahovina Samanli planine (Sakarya-Kocaeli-Yalova-Bursa) u severozapadnoj Turskoj]

Epifitska vegetacija mahovina Samanli planine u severozapadnom delu Turske je istraživana na osnovu 191 snimka uzetih Braun-Blanquet metodom sa stabla drveća tokom 2015. i 2016. godine. Kao rezultat ovih istraživanja, utvrdeno je prisustvo 9 epifitskih asocijacija mahovina i 3 subasocijacije. Medu njima, 2 asocijacije i 2 subasocijacije, Neckero - Anomodontetum viticulosi, Neckero - Anomodontetum viticulosi - anomodontetosum viticulosi, Syntrichietum laevipilae, Syntrichietum laevipilae - orthotrichetosum lyellii, konstatovane su po prvi put na teritoriji Turske. Takode, epifitska vegetacija mahovina je analizirana pomoću multivarijantskih analiza, a uradene su i analize životnih formi i životnih strategija vrsta unutar vegetacijskih jedinica. Kao rezultat, dok su dugoživeće višegodišnje jedinke sa visokim reproduktivnim potencijalom dominantne u epifitskoj vegetaciji mahovina, najćešća životna forma je gusta prostirka. © 2018 Institute of Botany and Botanical Garden Jevremovac, Belgrade.; In the present study, epiphytic bryophyte vegetation of the Samanli Mountains (northwest Turkey) was investigated on the basis of 191 relevés taken from the trunks of trees by the Braun- Blanquet method between 2015 and 2016. Nine epiphytic bryophyte associations and three subassociations were determined as a result of this investigation. Among them, two associations and two subassociations, viz., Neckero - Anomodontetum viticulosi, Neckero - Anomodontetum viticulosi - anomodontetosum viticulosi, Syntrichietum laevipilae, and Syntrichietum laevipilae - orthotrichetosum lyellii, were recorded for the first time in Turkey. In addition, epiphytic bryophyte vegetation was classified and ordinated using multivariate analysis techniques such as two-way indicator species analysis and detrended correspondence analysis. Besides that, the life form and life strategies of the species within syntaxa were analysed. As a result, it is established that while perennial stayers with a high sexual reproductive effort were dominant within the epiphytic bryophyte vegetation comparatively, the most abundant life form was the mat rough type.
