The genetic diversity and phylogeography of maternal lineages in Ursus arctos Linnaeus, 1758 (the brown bear) have been studied extensively over the last two decades; however, sampling has largely been limited to the northern Holarctic, and was possibly biased towards lineages that recolonized the vast expanses of the north as the Last Glacial Maximum (LGM) ended. Here we report the genetic diversity and phylogeography of U.arctos from Turkey based on 35 non-invasive samples, including five from captive individuals. Bayesian phylogenetic analyses based on a 269-bp fragment of the mitochondrial DNA control region revealed 14 novel haplotypes belonging to three major lineages. The most widespread lineage was found to be the Eastern clade3a, whereas geographically more restricted Western and Middle Eastern lineages were reported for the first time in Turkey. A specimen from the Taurus mountain range carried a haplotype closely related to the presumably extinct bears in Lebanon. Moreover, we identify a unique new lineage that appears to have split early within the Middle Eastern clade. Despite limited sampling, our study reveals a high level of mitochondrial diversity in Turkish U.arctos, shows that the ranges of both European and Middle Eastern clades extend into Turkey, and identifies a new divergent lineage of possibly wider historical occurrence. Obtaining these results with 35 samples also demonstrates the value of proper sampling from regions that have not been significantly affected by the LGM.(c) 2015 The Linnean Society of London

Maternal phyogeopgraphy of brown bears (Ursus Arctos) and testing the utility of non-invasive genetic samples Çilingir, Fatma Gözde; Bilgin, Cemal Can; Department of Biology (2012) The genetic diversity and phylogeography of brown bear maternal lineages have been studied extensively over the last two decades. In this study the genetic diversity and maternal phylogeography of non-invasively sampled 35 brown bears, including 5 captive individuals were reported from Turkey. In addition to the optimization of DNA extraction from hair, faeces and old skin samples and their PCRs, Bayesian phylogenetic analyses based on a 269 bp long piece of bear mitochondrial DNA were conducted and 14 nove...
Comparative molecular phylogenetics of Astragalus L. sections from Turkey with New World Astragalus species using nrDNA ITS sequences Dizkirici, Ayten; EKİCİ, MURAT; Kaya, Zeki (Springer Science and Business Media LLC, 2014-01-01) Comparative molecular phylogenetic study using nrDNA internal transcribed spacer region (ITS) sequences was carried out on species from three Astragalus L. (Fabaceae) sections from Turkey (Old World species) and the New World. A total of 56 taxa (179 accessions) including 30 species from Incani DC., 15 species from Hypoglottidei DC. and 11 species from Dissitiflori DC. section were used in the current study. The total length of the ITS region was 642 bp with 56 (8.7 %) parsimony-informative and 9 insertion\...
Genetic relationships among perennial and annual Cicer species growing in Turkey as revealed by allozymes Sudupak, MA; Kence, Aykut (Springer Science and Business Media LLC, 2004-05-01) Allozyme polymorphisms were used to assess genetic variation and relationships among ten Cicer species ( annuals and perennials) growing in Turkey. Using seven enzyme systems, 12 putative scorable loci were detected and surveyed for polymorphism in an accession collection including wild and cultivated forms. Variation was generally low within accessions and species, but common between species. Cluster analysis based on the pairwise genetic distance coefficients (Nei 1978) among accessions and species using ...
CLADISTIC TESTS OF MONOPHYLY AND RELATIONSHIPS OF BIOSTRATIGRAPHICALLY SIGNIFICANT CONODONTS USING MULTIELEMENT SKELETAL DATA - LOCHRIEA HOMOPUNCTATUS AND THE GENUS LOCHRIEA Atakul-Oezdemir, Ayse; Purnell, Mark A.; Riley, Nicholas J. (Wiley, 2012-11-01) Since the 1960s, huge progress has been made in reconstructing the multielement skeletons of conodont species and developing a biologically defensible taxonomy. Nevertheless, a widespread prejudice remains that certain parts of the conodont skeleton, particularly the P-1 elements, are more informative than others with regard to taxonomy and evolutionary relationships. Here, we test these views. A new partial multielement reconstruction of the skeleton of the biostratigraphically significant conodont origina...
An expanded molecular phylogeny of Plumbaginaceae, with emphasis on Limonium (sea lavenders): Taxonomic implications and biogeographic considerations Koutroumpa, Konstantina; Theodoridis, Spyros; Warren, Ben H.; Jimenez, Ares; Celep, Ferhat; Doğan, Musa; Romeiras, Maria M.; Santos-Guerra, Arnoldo; Maria Fernandez-Palacios, Jose; Caujape-Castells, Juli; Moura, Monica; de Sequeira, Miguel Menezes; Conti, Elena (Wiley, 2018-12-01) Plumbaginaceae is characterized by a history of multiple taxonomic rearrangements and lacks a broad molecular phylogenetic framework. Limonium is the most species-rich genus of the family with ca. 600 species and cosmopolitan distribution. Its center of diversity is the Mediterranean region, where ca. 70% of all Limonium species are endemic. In this study, we sample 201 Limonium species covering all described infrageneric entities and spanning its wide geographic range, along with 64 species of other Plumba...
