Abstract

Lichenized fungi are the most dominant macro organisms in Antarctic terrestrial ecosystems. Studies on lichens in Antarctica have a history of approximately two centuries. Especially with the recent use of DNA-based techniques in taxonomy studies, lichen biodiversity studies in Antarctica has accelerated. Dismal Island is the largest of the Faure Islands, 1.9 kilometers long and 60 meters high, mostly covered with ice in Marguerite Bay on the west coast of Graham Land. In the literature, there is no study directly addressing or examining lichen biodiversity on Dismal Island. In this context, the aim of this study is to examine anatomically-morphologically and to perform DNA barcoding of some lichenized fungi species from Dismal Island. Lichen samples collected from Dismal Island during the 6th Turkish National Antarctic Scientific Expedition by the second author. The collected samples were identified by anatomical and morphological examinations and DNA barcoding was performed with ITS gene region primers. As a result of the study, DNA barcoding of 11 species was performed. This species are Austroplaca hookerii (C.W. Dodge) Søchting, Frödén &Arup, Buellia russa (Hue) Darb., Candelariella flava (C.W. Dodge & Baker) Castello & Nimis, Mastodia tessellata (Hook & Harv.) Hook & Harv., Polycauliona candelaria (L.) Frödén, Arup & Søchting, Rhizoplaca aspidophora (Vain.) Follmann, Rhizocarpon geographicum (L.) DC., Tephromela atra (Huds.) Hafellner ex Kalb., Tetramelas anisomerus (Vain.) Elix., Umbilicaria antarctica Frey & I.M. Lamb., Usnea antarctica Du Rietz.

Özet

Likenleşmiş mantarlar Antarktika karasal ekosisteminin en baskın makroorganizmalarıdır. Antarktika’daki likenlerle ilgili çalışmalar yaklaşık 2 asırlık bir geçmişe sahiptir. Özellikle taksonomi tabanlı DNA-temelli tekniklerin kullanımı ile Antarktika’daki liken biyoçeşitlilik çalışmaları hız kazanmıştır. Dismal Adası Faure Adaları’nın en büyüğüdür, Graham Toprakları’nın batı kıyısındaki Margurite Limanı’nda bulunan 1.9 kilometre uzunluğunda ve 60 metre genişliğindeki kıta genellikle buzla kaplıdır. Literatüre bakıldığında Dismal Adası’ndaki liken biyoçeşitliliğini inceleyen ya da bundan bahseden direkt bir çalışma yoktur. Bu bağlamda bu çalışmada Dismal Adası’ndaki bazı likenleşmiş mantarların anatomik-morfolojik olarak incelenmesi ve DNA barkodlamalarının yapılması amaçlanmıştır. Liken örnekleri ikinci yazar tarafından 6. Türk Ulusal Antarktika Bilim Seferi sırasında Dismal Adası’ndan toplanmıştır. Toplanan örnekler anatomik ve morfolojik incelemelerle teşhis edilmiştir ve ITS gen bölgesi primerleri kullanılarak DNA barkodlamaları gerçekleştirilmiştir. Çalışma sonucunda 11 türün DNA barkodlaması gerçekleştirilmiştir. Bu türler Austroplaca hookerii (C.W. Dodge) Søchting, Frödén &Arup, Buellia russa (Hue) Darb., Candelariella flava ( C.W. Dodge & Baker) Castello & Nimis, Mastodia tessellata (Hook & Harv.) Hook & Harv., Polycauliona candelaria (L.) Frödén, Arup & Søchting, Rhizoplaca aspidophora (Vain.) Follmann, Rhizocarpon geographicum (L.) DC., Tephromela atra (Huds.) Hafellner ex Kalb., Tetramelas anisomerus (Vain.) Elix., Umbilicaria antarctica Frey & I.M. Lamb., Usnea antarctica Du Rietz şeklindedir
