Ören, Muhammet; Alataş, Mevlüt; Uyar, Güray
Işık Dağı, İç Anadolu Bölgesinde Ankara’nın kuzey doğusunda bulunmakla birlikte, Batı Karadeniz ve İç Anadolu Bölgeleri arasındaki iklimsel bir geçiş kuşağında yer almaktadır. Sahip olduğu bu iklimsel özellikleri ve kendine has topoğrafik yapısı sayesinde floristik açıdan oldukça zengin olan bu bölgenin, maalesef şimdiye kadar tüm briyofloristik yapısının aydınlatılması için detaylı bir çalışma yapılmamıştır. Bu çalışmada, 2019 yılının Haziran ve Ekim aylarında Işık Dağı’nın 29 farklı lokalitesinden yaklaşık 450 briyofit örneği toplanmıştır. Toplanan örneklerin değerlendirilmesi sonucunda, bölgeden ciğerotlarından 10 familya ve 11 cinse ait 18 takson ve karayosunlarından ise 32 familya ve 73 cinse ait 144 takson olmak üzere, toplamda 162 takson tespit edilmiştir. Bu taksonlardan; Dicranella staphylina H. Whitehouse Türkiye’den ikinci kez rapor edilmiştir. Ayrıca Tortella inflexa (Bruch) Broth. ve Weissia rutilans (Hedw.) Lindb., A2 karesi için yenidir. Dahası, Çankırı ili için 18, Ankara ili için ise 49 taksonun ilk defa kaydı, bu briyoforistik listede verilmektedir.

Hair and nail samples were collected during a period of October to December 2012 from 63 healthy humans whohave been living in Zonguldak for at least ten consecutive years. The humans aged over 30 years and having noserious health problems were participated in the study. The methodology involved the collection, ultrasoniccleaning and microwave digestion of samples. The measurements of trace metals (As, Cu, Zn, Se, Cd, Pb, Cr, Feand Ni) in samples were performed with ICP-MS. The predominant metals determined in the both hair and nailsamples were the essential metals with the decreasing concentrations in the order of Zn>Fe>Cu. Other metalsdetermined in the hair samples followed the concentration order of Pb>Se>Ni>Cr>As>Cd, whereas in the nailsamples, the order was Se>Ni>Cr>Pb>As>Cd. Subgroups were formed according to location and gender. Se andFe concentrations in hair samples obtained from urban residents were significantly higher. With regard to nailsamples, the rural residents exhibited more elevated Fe levels significantly. Gender had a significant influence onthe concentration of Zn and Cu in hair samples with females presenting higher values. However, the effect ofgender on the trace metal concentrations in nail samples was negligible. The metal concentrations obtained forZonguldak were within or below the values reported worldwide.

Bu çalışmada, Sakarya ili, Akyazı ilçesinin (Türkiye) epifitik briyofit vejetasyonu araştırılmıştır. 2017 yılının farklı vejetasyon dönemlerinde, ağaç gövdelerinden alınan toplam 85 örneklik alan, Braun-Blanquet metodu-kullanılarak sınıflandırılmış, Detrended Correspondence Analysis (DECORANA) ve Two-Way Indicator Species Analysis (TWINSPAN) kullanılarak da düzenlenmiştir. TWINSPAN sınıflandırma tekniği, üçüncü seviyede sekiz kümeyi içeren iki ana vejetasyon grubu üretmiştir. DECORANA sonuçları, epifitik toplulukların dağılım modellerinin, kurakçıldan nemliye taban ve üst bölgeler boyunca değiştiğini göstermiştir. Çalışma alanındaki epifitik topluluk farklılaşması için en önemli ekolojik faktör, ordinasyon diyagramına göre, epifitik habitatların nemidir. Sonuç olarak, yapılan bu çalışmada altı epifitik briyofit birliği ve iki alt birlik tespit edilmiştir. Bunlar arasından; Orthotrichetum pallentis Türkiye’den ikinci kez, Pterigynandretum filiformis -leucodontetosum sciuroidis ise Türkiye’den ilk kez kaydedilmiştir. Dahası, Orthotrichetum pallentis - isothecietosum alopecuroidis subass. nova, Sakarya ilinin Akyazı ilçesi'nden yeni bir epifitik altbirlik olarak tanımlanmıştır. Bu sintaksonların; nem, ışık, asidite gibi ekolojik ve floristik karakteristikleri detaylı açıklamalarıyla birlikte verilmiştir.

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.

In this study, epiphytic bryophyte flora and vegetation were investigated of Boraboy and Destek forests in Amasya province (Turkey). A total of 22 bryophyte taxa (19 mosses, 3 liverworts) were recorded in the research site. As a result of the investigation of 32 sampling releves taken from the trunks by the Braun-Blanquet method, two epiphytic bryophyte associations (Orthotrichetum pallentisand Orthotrichetum striati) belonging to the Ulotion crispaealliance were detected. Among these syntaxa Orthotrichetum pallentiswas recorded for the first time from Turkey. Furthermore, the life forms and life strategies spectrum in syntaxa were analyzed. Analysis result indicates a distinct correlation between life forms, strategies and ecological conditions of the area. Weft and cushion are dominant life forms, Perennial stayers with high sexual reproductive effort is dominant life strategy in the syntaxa. In addition, the ecological characteristics of bryophyte taxa were evaluated. According to these results the largest number of epiphytic bryophytes in the area are mesophytic, sciophyte and subneutrophyte.
