The epiphytic bryophyte succession of Buxus sempervirens forests in the Fırtına Valley, Rize (North Türkiye)

In this study, the epiphytic bryophyte succession of the Buxus sempervirens L. forests in Fırtına Valley (Çamlıhemşin-Rize, North Türkiye), one of the nine biodiversity hotspots in Türkiye, were investigated. For this purpose, a total of 60 sampling plots were taken from the live trunks of the B. sempervirens trees of different ages. Twenty-nine epiphytic bryophyte species were determined (24 mosses and 5 liverworts) within the sample plots. Also, six different life form types and four different habitat affinity categories were determined. The mat type life form is in the first place with 34.4% whereas the and cortico-saxicolous species are the most common with 51.7%. Two-Way Indicator Species Analysis (TWINSPAN) classified the epiphytic bryophyte communities on the trunks of the B. sempervirens at the second level into two main clusters (A and B) and three sub-clusters (A1, B1 and, B2). Detrended Correspondence Analysis (DCA) axis 1 was interpreted as gradient along the height of the epiphytic habitat (from the lower base to the upper zone) on trunks and the DCA axis 2 was interpreted as gradient of moisture (from mesic to xeric). Exsertotheca crispa (Hedw.) S.Olsson, Enroth & D.Quandt was the species with the highest Index of Ecological Significance (IES) value on the lower bases of the aged trees. Species diversity and epiphytic cover in the upper zones were lower than in the basal and middle zones in the study area. While Metzgeria furcata, (L.) Corda, Oxyrrhynchium hians (Hedw.) Loeske, Plagiothecium nemorale (Mitt.) A.Jaeger, and Radula lindenbergiana Gottsche ex C.Hartm were only found on old trees, Ctenidium molluscum (Hedw.) Mitt. and Pseudoleskeella nervosa (Brid.) Nyholm were only found on middle-aged trees

Burdur ilinde karayollarının yakınından toplanan bazı karayosunu örneklerinde ağır metal seviyelerinin belirlenmesi

The main sources of atmospheric heavy metals deposition are agricultural activities, fossil fuels, central heating stations and the exhaust gases of motor vehicles. In this study, the total of 29 mosses samples were collected from contaminated points near the Isparta-Antalya, Burdur-Denizli, Burdur-Afyonkarahisar, Burdur-Fethiye (Muğla) and Burdur-Antalya highways (2-20m) and uncontaminated areas in 2012. Samples were analyzed by flame and graphite furnace atomic absorption spectrometry (AAS) later microwave digestion methods. The highest accumulation levels detected as µg.g−1 Fe (1419.02)>Zn (158.44)>Mn (362.77)>Ni (109.53)>Cr (60.51)>Pb (30.38)>Cd (35.866)>Cu (25.17) for mosses. Element levels are differ depending on moss species and the location of collecting localities.Atmosferik Ağır metal birikiminin ana kaynakları, tarımsal faaliyetler, fosil yakıtlar, merkezi ısıtma istasyonları ve bölgedeki motorlu taşıtların egzoz gazlarıdır. Bu çalışmada, 2012 yılında Isparta-Antalya, Burdur-Denizli, Burdur-Afyonkarahisar, Burdur-Fethiye (Muğla) ve Burdur-Antalya karayollarının yakınından (2-20m) kirlenmiş bölgeden ve bu yollara uzak noktalardan temiz bölgeden 29 karayosunu örneği toplanmıştır. Örnekler mikrodalga çözünürleştirme sonrasında alev ve grafit fırın atomik absorpsiyon spektrometresi (AAS) metodu ile analiz edilmiştir. Karayosunları için en yüksek birikim seviyeleri µg.g−1 olarak şu şekilde tespit edildi; Fe (1419.02)>Mn (362.77)>Zn (158.44)>Ni (109.53)>Cr (60.51)>Pb (30.38)>Cd(35.866)>Cu (25.17). Element seviyesi, karayosunu türlerine ve toplanma lokalitelerinin durumuna bağlı olarak farklıdır

New Bryophyte Records from Turkey and Southwest Asia

Five bryophytes collected during bryological forays to the Ordu and Burdur regions of Turkey were of particular interest. Among them, Orthotrichum hookeri, Plagiothecium neckeroideum and Thamnobryum neckeroides were found to be new to Turkey. Orthotrichum hookeri and Plagiothecium neckeroideum are also new to Southwest Asia.
