The Anatolian Biogeographical Region is unique in the Palearctic realm, with high plant and butterfly species richness and populations of globally threatened birds, mammals and herptiles (amphibians and reptiles). It is a place of diverse land-use practices, dating back to the earliest farming practices in the world. Among 10,930 species of vascular plants, birds, butterflies, mammals and herptiles distributed in Turkey, we identified 1130 living predominantly in steppic environments and being classified either as threatened, near-threatened or data deficient at the national level, if not globally. A total of 28 effective protected areas were present in the region, covering 1.5 % of the 391,597 km(2) land area. Only 16.2 % of the threatened and near-threatened species (n = 809) were distributed within the protected area network, ranging from 94.1 % for birds to as low as 12.9 % for vascular plants. The total area of steppe and steppe forest vegetation has been reduced by at least 44 % of its former extent due to diverse habitat destructive activities. The most significant threats arise from unsustainable agricultural activities including overgrazing, conversion to croplands and afforestation. To maintain steppe diversity, we propose a "to-do list", including mainstreaming biodiversity, effective implementation of Turkey's Rangeland Act, conducting effective environmental impact assessments, establishing an effective site network for steppe biodiversity conservation and filling gaps in scientific knowledge.


Molecular phylogenetics of Turkish Salix L. species
Acar, Pelin; Kaya, Zeki; Department of Biology (2017)
Chloroplast (trnT-F, matK and rbcL) and nuclear genome (ITS) regions were used to explore the evolutionary relationships of Salix species which are native to Turkey. Morphological analysis with the utilization of Principal Component Analysis (PCA) was also carried out. Such a combined sequence data from cpDNA and nrDNA genes enabled reliable subgenus-level classification of Turkish willows (subgenus Salix and Vetrix). Morphological and genetic results agree with traditional taxonomic concepts in clustering ...
Assessment of genetic diversity in picea orientalis (l.) link. in genetic resources by microsatellites
Özdilek, Aslı; Kaya, Zeki; Temel, Fatih; Department of Biology (2015)
Picea comprises about 40 species in the world. One of these species, oriental spruce (Picea orientalis (L.) Link.) is naturally distributed in northeastern Turkey, mostly in Artvin Province and in a part of Georgia close to the coast of the Black Sea region. The limited distribution of species and increased anthropogenic threats to its genetic resources signify the importance of studying genetic diversity of the species to have better conservation and management programs. Here, we report the first high thro...
Molecular phylogenetic position of Turkish abies (pinaceae) based on noncoding trn regions of chloroplast genome
Özdemir Değirmenci, Funda; Kaya, Zeki; Department of Biology (2011)
Abies is the second largest genus of family Pinaceae (after Pinus), consisting of about 51 species, all native to the Northern Hemisphere. There are six native taxa belonging to this genus growing in pure and mixed stands in Turkey. Abies cilicica subsp. isaurica, Abies nordmanniana subsp. bornmülleriana, Abies nordmanniana subsp. equi-trojani, Abies x olcayana are endemic and considered as lower risk (LR) species. To determine the genetic relationships in Turkish firs, 18 populations of different subspecie...
Updated-extended molecular time and molecular phylogeny of Gundelia species native to Turkey
Fırat, Mehmet; Ateş, Mevlüde Alev; Kaya, Zeki (2021-08-01)
Generally, Gundelia tournefortii is considered as the sole representative of the genus and the other species of Gundelia as synonyms. Recent studies suggest that the genus is rich with 22 species. Off these, thirteen are endemic to Turkey. To date, no comprehensive molecular study dealing with speciation exists in the genus. To address the speciation at the molecular level, fresh leaves from 57 samples representing 15 species from their natural ranges in Turkey were obtained by sampling over several years a...
Scanning electron microscope (SEM) and light microscope (LM) studies on the seed morphology of Verbascum taxa (Scrophulariaceae) and their systematic implications
Cabi, Evren; Baser, Birol; Yavru, Ahter; Polat, Filiz; Toprak, Umut; KARAVELİOĞULLARI, FAİK AHMET (2011-06-01)
Verbascum L. is the largest genus of the family Scrophulariceae and includes several species are of medicinal importance. In this study, external seed morphologies of 30 taxa included in Group A belonging to genus Verbascum L. (Scrophulariaceae) in Turkey, have been investigated using SEM (Scanning Electron Microscopy) and LM (Light Microscopy). Light microscope observations showed that seed size ranges from 0.3 mm to 1.5 mm in length and 0.1 to 0.6 in width. Seeds vary from oblong, oblong prismatic, trigon...
