    (KMK Scientific Press, 2019) Gözcü, Merve Can; Uyar, Güray; Ören, Muhammet; Ezer, Tülay; Alataş, Mevlüt
    The present study was performed on the Samanlı Mountains, which is extending from Sakarya province to Yalova province, in North-West Turkey. During this study, eight field trips were organized to the research area at different seasons between the years 2013 and 2016. Throughout these studies, with an examination of 3630 bryophyte specimens collected from 189 stations, together with 2 from Anthocerotophyta (hornworts), 61 from Marchantiophyta (liverworts), 306 from Bryophyta (mosses), in total 369 specific and infraspecific taxa, belonging to 70 families and 156 genera, have been identified. According to grid square system of Turkey which was adopted by Henderson, 68 taxa for A1 square and 24 taxa for A2 square are new records. Among them, Fissidens curvatus Hornsch., Thamnobryum neckeroides (Hook.) E.Lawton, Plagiothecium neckeroideum Schimp. and Riccia beyrichiana Hampe were recorded for the second time in Turkey. In addition, the present paper reports the first records of Cephaloziella massalongi (Spruce) Müll.Frib, which has been classified as rare (R) in the Red data book of European bryophytes, and Scapania scandica (Arnell et H.Buch) Macvicar in Turkey. Some morphological features, the ecological characteristics and the distribution map of the species are given, along with photographs of diagnostic details. © (2023), (KMK Scientific Press).

    The Epiphytic Bryophyte Communities of Akyazı District (Sakarya, Turkey): A Multivariate Study of Community-Habitat Relationships
    (2019) Alataş, Mevlüt; Uyar, Güray; Ezer, Tülay; Ören, Muhammet
    In this study, epiphytic bryophyte vegetation of the Akyazı District in Sakarya Province (Turkey) was investigated. Inthe different vegetation periods of the year 2017, a total of 85 relevés taken from the trunks of trees and wereclassified by Braun-Blanquet method and regulated by using Detrended Correspondence Analysis (DECORANA)and Two-Way Indicator Species Analysis (TWINSPAN). TWINSPAN classification technique produced two mainvegetation groups include eight clusters at the third level. The results of DECORANA indicated that the distributionpatterns of epiphytic communities change from xeric to mesic and along the lower base and upper zones. The mostimportant ecological factor for the epiphytic community differentiation in the study area, according to the ordinationdiagram, is humidity of the epiphytic habitats. Consequently, six epiphytic bryophyte associations and twosubassociations were determined in the present paper. Among them; Orthotrichetum pallentis for the second time andPterigynandretum filiformis -leucodontetosum sciuroidis were recorded for the first time in Turkey. Moreover,Orthotrichetum pallentis - isothecietosum alopecuroidis subass. nova was described as a new epiphytic associationfrom the Akyazı District of Sakarya Province. Floristic and ecological characteristics such as; (humidity, light,acidity) of these new syntaxa are given with detailed descriptions.
