We describe the spatial distribution of the genus Acantholimon Boiss. (Plumbaginaceae) taxa in Turkey, and assess the role that environmental variables may be playing on this distribution. We collected a large number of specimens from 418 geo-referenced sampling sites between 2000 and 2004, and established a point database using geographic information systems (GIS) software. As a result, we identified and mapped 67 taxa; 43 of the determined taxa appear to be endemic. We re-evaluated the current conservation status of the taxa at a national level using recent IUCN Red List categories. In addition, we extracted the corresponding environmental variables of each determined point from the updated and available environmental raster map layers of Turkey and analysed the obtained taxa and environmental data by Hierarchical Clustering and Canonical Correspondence Analysis (CCA). Hierarchical Clustering delineated the subgroups, which have similarities at various levels in respect to environmental variables. The CCA results indicated that 8 environmental variables including longitude, distance to sea, maximum temperature, mean temperature, minimum temperature, potential evapotranspiration, elevation, and precipitation are the most effective in explaining the spatial distribution of the 18 Acantholimon taxa in Turkey.

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...
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\...
Revision of Vicia L. (Leguminosae) in the Central Anatolia, Turkey Binzat, Okan Kaan; Doğan, Musa; Department of Biology (2012) In this revisional study based on the the genus Vicia in Central Anatolia large quantities of data have been compilled from specimens representing the group of the taxa being studied. These data were then synthesized to make taxon descriptions, keys, geographical distributions and ecological preferences. Since 2009, about 700 specimens have been collected from Central Anatolia and examined as the research materials. In addition, a large number of specimens have also been studied in the following herbaria AN...
Description of an early ontogenetic evolutionary step in Lepidorbitoides Lepidorbitoides bisambergensis asymmetrica subsp n Early Maastrichtian central Turkey ÖZCAN, ERCAN; Altıner, Sevinç (2001-01-01) Lepidorbitoides bisambergensis is characterised by having a 'quadriserial' embryo without any chamberlet directly arising from the deuteroconch and is a very diagnostic and common species in Lower Maastrichtian flysch successions in Anatolia. Some populations of this species present an early ontogenetic morphologic feature which is characterised by distinctly asymmetric early chamber arrangement recognised in the horizontal sections. This asymmetry is mainly caused by the pronounced difference in the size o...
On the formation of net phytoplankton patches in the southern Black Sea during the spring Uysal, Zahit (2002-10-01) Species composition, community structure and spatial distribution of net phytoplankton in the southern Black Sea have been studied. In the fraction over 55 mum, diatoms were found to be predominant in cell abundance and followed by dinoflagellates. Net phytoplankters were found to be more abundant in the southwestern sector, especially near the Bosporus and near Sakarya River mouth. MDS (Multi-Dimensional Scaling) analysis has projected four distinct patches along the coast, two of which appear to occupy sm...
