AN OVERVIEW OF THE GEOBOTANICAL STRUCTURE OF TURKISH PINUS SYLVESTRIS AND CARPINUS BETULUS FORESTS

YUCEL, Ersin/0000-0001-8274-7578WOS: 000260158200017Pinus L and Carpinus L. are the two widely distributed genera of gymnosperms being represented by 80 and 170 species respectively. The former has 5 species in Turkey and latter 2 species namely; P.pinea, P.halepensis, P.brutia, P.sylvestris, P.nigra ssp.pallasiana, Carpinus betulus and C.orientalis. In this paper an attempt has been made to present all overview of the geobotanical structure of Pinus sylvestris L. and Carpinus betulus L. in Turkey. Out of 20.2 million hectares of forests in Turkey yellow pine covers nearly 1.3 million ha and hornbeam species around 10 thousand ha. The forests of P. sylvestris are found in North, Northeast Anatolia, oil Murat Mountains around Kutahya and C. betulus mainly in Thrace, Marmara, Black Sea and Inner Anatolia. P.sylvestris is represented by 9 associations;Pinus sylvestris-Vaccinum myrtillus, Pinus sylvestris - Daphne glomerata, Pinus sylvestis - Astragalus adzharicus, Pinus sylvestris-Lilium ciliatum, Pinus sylvestris-Daphne pontica, Pinus sylvestris-Populus tremula, Populo-Pinetum sylvestris, Pinus sylvestris-Orthilio secundo, Pinus sylvestris Llazica-Epimedium pinnatum subsp. colchicum, Triseto-Pinetum sylvestris. whereas C.betulus has only 6 associations Carpinus betulus-Scaligeria tripartita, Carpinus betulus-Acer campestre, Quercus petraea ssp. iberica-Carpinus betulus, Carpinus betulus-Quercus petrae ssp. iberica, Fagus orientalis-Carpinus betulus. P.sylvestris associations are floristically rich having 275 taxa as compared to C.betulus forests which embody only 121 taxa. The life form spectrum of P.sylvestris forests includes 146 chamaephytes, 44 hemicryptophytes, 40 phanerophytes, 28 cryptophytes and 17 therophytes, whereas C.betulus forests include 23 phanerophytes, 39 chamephytes, 36 hemicryptophytes,14 cryptophytes and 8 therophytes. Phytogeographically a major part of the taxa in P.sylvestris forests are Euro-Siberian elements (24.4%) followed by the Irano-Turanian (6.4%) and Mediterranean (1.4%). In C.betulus forests the distribution is as follows; Euro-Siberian-Euxine elements (83%) followed by Mediterranean (14%) and Irano-Turanian (3%). These observations stress the fact that geobotanically these forests prefer mainly high altitude moist habitats in the north and northeastern parts of Turkey

STUDIES ON TRACE METALS IN SOILS AND PLANTS GROWING IN THE VICINITY OF COPPER MINING AREA - LEFKE, CYPRUS

WOS: 000264461800017Soil and plant samples were taken from different areas around the tailing ponds of CMC (Cyprus Copper Mines), an abandoned site from the Lefke region of Cyprus. The determination of the trace metals was carried out using a Varian ICP-AES. In the soils supporting these plants, the values varied between 1.4000-25.380 (Fe++); 43-217 (Zn++); 0-67 (Pb++); 1-8 (Cd++); 0.77-28.60 (Cu++); 20-89 (Ni++); 0.05-0.29 (Cr++) mu g/g dry weight. In the above-ground parts of the plants, the concentrations varied between 275-4,120 (Fe); 9.5-67 (Zn); 0-13 (Pb); 0-4 (Cd); 0.12-1.85 (Cu); 10-18 (Ni); 0.11-0.28 (Cr) mu g/g. The values in the soils are higher than that in above ground parts. These results show that there are serious trace metal problems in the soil, and these keep on accumulating in the plants in the vicinity of tailing ponds

Canonical correlation analysis for studying the relationship between the basic morphological and some soil chemical characteristics of Centaurea mucronifera DC. (Asteraceae)

YUCEL, Ersin/0000-0001-8274-7578WOS: 000259602300104This aim of this study was to investigate the relationship between the basic morphological features and some soil chemical characteristics in order to enlighten the differentiation in the Centaurea mucronifera populations distributed at 16 different places under varying environmental conditions. For this purpose method of Canonical correlation analysis (CCA) was used. The results revealed that morphological features like length of terminal leaves (Y3), length of capitula (Y4), length of involucrum (Y5) and length of achen (Y6) are affected positively by N (X6) and Ca2+ (X7) in the soil but the length of plant (Y1), length of basal leaves (Y2) and length of pappus (Y7) are affected negatively.Anadolu University Scientific Research FundAnadolu University [011042]The authors are grateful to Anadolu University Scientific Research Fund for financial support (Project No: 011042)

Midgut volvulus: Value of multidetector computed tomography in diagnosis

Midgut voluulus is a rare complication of intestinal malrotation in adults. We present a case of intestinal malrotation with surgically proven midgut volvulus. Multidetector computed tomography with postprocessing of imaging data using three-dimensional reconstruction techniques provided better demonstration of the abdomen than other imaging modalities. To our knowledge, this is the first presentation of midgut voluulus on multidetector computed tomography in adults. The literature on midgut volvulus is also reviewed and imaging findings of this disease are discussed
