Samples of fossil tooth enamels taken from different depths of Karain Cave (Antalya, Turkey) were studied by the ESR method. The accumulated doses (D(E)s) of the samples were determined using the paramagnetic center at g = 2.0020 +/- 0.0003 by means of three different microwave power conditions. It is found that the dating signal at g = 2.0020 (Delta Hpp approximate to 0.34 mT) is disturbed significantly by the isotropic signal at g = 2.0007 +/- 0.0003 at high microwave power. The lifetime of this signal is significantly smaller than the lifetime of the dating signal. However, the statistical uncertainty caused by different microwave powers is still within the total uncertainty in the age determination of the tooth enamels under investigation. The ESR ages of the samples were calculated using early uranium (EU) and linear uranium (LU) uptake models. The ages due to EU and LU models are in agreement within an error of 10% due to the low uranium content of the samples.

Contribution to the knowledge of the pollen morphology of the genus Salvia (Lamiaceae) ÖZLER, HÜLYA; KAHRAMAN, AHMET; PEHLİVAN, SEVİL; Doğan, Musa; BAŞER, BİROL; FİŞNE, AHTER; Bagherpour, Safi (Magnolia Press, 2020-01-14) The pollen grains of 19 Turkish Salvia species in Aethiopis, Drymosphace, Hemisphace, Hymenosphace and Salvia sections, 13 of which are endemic to Turkey, were investigated, documented and illustrated through Light Microscopy (LM) and Scanning Electron Microscopy (SEM). This study provides pollen data of 14 species for the first time. The pollen grains of the species examined are monads, isopolar, radially symmetrical and hexacolpate, mostly medium in size, slightly elliptic to more or less circular in pola...
CALCAREOUS NANNOFOSSILS FROM THE LATE JURASSIC EARLY CRETACEOUS OF NORTHWEST ANATOLIA, TURKEY Altıner, Sevinç (Wiley, 1993-12-01) Within the framework of an integrated stratigraphy, a detailed biostratigraphic study of Late Jurassic-Early Cretaceous (Tithonian-Valanginian) calcareous nannofossils was carried out in north-west Anatolia, Turkey.
A Proposal for the preservation and integrated presentation of archaeological and natural resources in the case of METU Campus area Bağcı, Latife Sema; Bertram, Jan Krzysztof; İlgezdi Bertram, Gülçin; Department of Settlement Archaeology (2010) The subject of presentation of archaeological resources is still a developing concept in Turkey. The concepts of educational value and concern, needs a more common recognition and more practice in this context. The same statement goes for the management of natural resources. However, proper public presentation of archaeological and natural resources and public education in those is crucial for the protection of these resources. Moreover, an integrated presentation, approaching the archaeological resources w...
Diurnal gut pigment rhythm and metabolic rate of Calanus euxinus in the Black Sea Besiktepe, S; Svetlichny, L; Yuneva, T; Romanova, Z; Shulman, G (Springer Science and Business Media LLC, 2005-04-01) The vertical distribution, diel gut pigment content and oxygen consumption of Calanus euxinus were studied in April and September 1995 in the Black Sea. Gut pigment content of C. euxinus females was associated with diel vertical migration of the individuals, and it varied with depth and time. Highest gut pigment content was observed during the nighttime, when females were in the chlorophyll a (chl a) rich surface waters, but significant feeding also occurred in the deep layer. Gut pigment content throughout...
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\...
