“…macrolepis and Q. brantii over Turkey are geographically separated by the Anatolian Diagonal (Davis 1971;Ekim and Güner 1986;Borazan and Babaç 2003;Uslu et al 2011;Uslu and Bakış 2012). A similar geographical isolation mechanism was also reported between Q. trojana and Q. libani by Borazan and Babaç (2003) and Uslu and Bakış (2012).…”

Oaks are classified heavily based on the leaf morphology. However, identification of specimens without acorns is usually controversial in Cerris section. Although members of Cerris section have a broad distribution area, there are only few taxonomic studies. Therefore, the current study is the first to show the discrimination of species in Cerris section based on leaf characters from Turkey. Discrimination among the members of Cerris section over Turkey (Q. cerris L. var. cerris, Q. ithaburensis Decne. subsp. macrolepis (Kotschy) Hedge and Yalt, Q. brantii Lindley, Q. libani Olivier, and Q. trojana P. B. subsp. trojana.) was aimed and variations within and among the species based on 15 qualitative leaf characters was presented. In this work we have studied the natural variability of these species by analysing leaf materials collected from 44 populations around Turkey. Cluster Analysis (CA) and Principal Component Analysis (PCA) were performed to assess intra-specific differentiation and to compare the distribution of variance in the individual and population level. The results showed that the leaf characters presented a good discrimination of five Cerris taxa in PCA at the population level, but the relationships between Q. ithaburensis subsp. macrolepis and Q. brantii showed complex groups in CA. Among the studied taxa, the highest variation was found within Q. cerris populations. In this work, we obtained discrimination of Cerris section species from Turkey based on leaf characters which is quite useful for those herbarium specimens without acorns and in other systematic observations.

“…Besides its location and phytogeographical regions, Anatolian Diagonal which divides Anatolia as eastern and western parts is another factor affecting species diversity, number and distribution [4,[12][13][14][15]. Anatolian Diagonal separates many plant and animal species into eastern and western Anatolia.…”

The genus Quercus L. represented by 18 species belonging to three sections (Quercus L., Ilex Loudon and Cerris Loudon) in Turkey has a problematic taxonomy especially because of widespread hybridization observed frequently among oak species. In the present chapter, detailed karyotypic investigation of the 16 oak species from three sections in Turkey, their taxonomic relationships with each other and European oaks and finally situations that increase the variation and taxonomic problems among oak species in Turkey were evaluated to contribute to the taxonomic relationships of the genus. The somatic chromosome number in all taxa examined confirmed that the chromosome number of the genus is consistent with 2n = 24. However, some differences were determined among species, although similar results were observed in many oak species in Turkey contrary to European oaks.

“…than any other country in Europe and the Middle East, at least 17 species of which three are considered nationally endemic (Kavgaci et al, 2010;Uğurlu et al, 2012). The different oak species are distributed all over the country, with the highest diversity in Marmara region (Uslu et al, 2011), covering nearly six million hectares of the land area or 26% of the Turkish forests (OGM, 2015). Previously commonly utilized for pollarding, coppicing and grazing, oak forests in Turkey have an old tradition as important sources of livelihood for rural communities (Kaniewski et al, 2007).…”

Natural and semi-natural oak (Quercus spp.) forests in Turkey are rich ecosystems of high conservation value that are increasingly threatened by logging and transformation into coniferous plantations. They harbor a diverse fauna and flora, but the current knowledge of their associated biodiversity is limited for many groups of organisms. In this paper, we present our preliminary results from inventories of the birds inhabiting various oak forests located in Isparta province in southwestern Turkish Anatolia. The bird species diversity was assessed both quantitatively and a qualitatively using random observation walks and fixed-radii point counts in 17 oak forests ranging in mean age from 30 years up to 300 years. A total of 52 bird species belonging to 43 genera and 24 families were identified. The three most abundant species were Eastern Bonelli's Warbler (Phylloscopus orientalis), Common Chaffinch (Fringilla coelebs) and Common Blackbird (Turdus merula). Birds of national or international conservation concern are highlighted. Furthermore, we present an updated taxonomical species checklist.
