    (Parlar Scientific Publications (P S P), 2020) Sayin, Selin; Soyler, Oktay; Mazlum, Yavuz; Pamukoglu, Nahit; Habiboglu, Ogulcan; Ugur, Sinem
    Algae based biofertilizers have an increasing prevelance both in academic studies and usage as commercial products. In this study, ten different species of macroalgae - Stypopodiutn scthimperi (Phaeophyta), Sargassum vulgare (Phaeophyta). Dictyota dichotoma (Phaeophyta). Cystoseria cotnpressct (Phaeophyta), Padina pavonia (Phaeophyta). Ulva intestinalis (Chlorophyta), Halopteris scoparia (Phacophyta), Laurencia obtusa (Rhodophyta), Jania rubens (Rhodophyta) and Cystoseira corniculata (Phaeophyta) collected from Iskenderun Bay on the northeastern Mediterranean coast, were subjected to fermentation process. In order to obtain fermented algal fertilizers (FAF), two different fermentation starters were used; sugar beet molasses (Beta vulgaris) alone and combination of brewer's yeast (Saccharomyces cerevisiae) 2, sugar beet molasses. Chemical contents of FAFs were determined and combining brewer's yeast and sugar beet molasses as fermentation starter resulted in higher content of organic matter, total N, total K2O, water-soluble Ca, SO3 in FAF (p <0.05).

    Karyotypic studies of Meriones dahli Shidlovsky, 1962 (Rodentia: Muridae) from Turkey
    (Univ Florence Botany Inst, 2011) Baydemir, Nursel Asan; Demirbas, Yasin; Pamukoglu, Nahit; Albayrak, Irfan; Yagci, Tuba
    In this study, conventionally stained, C- and Ag-NOR banded karyotypes of Dahl's jird, Meriones dahli, were reported from Turkey. The species had a karyotype of 2n=50, NFa=74 and NF=78. The X and Y chromosomes were submetacentrics in all specimens examined. Blocks of constitutive heterochromatin were located in the pericentromeric areas of autosomes including the X and Y chromosomes. Interstitial C- bands are also detected in the long arms of one of the largest acrocentric pairs. Nucleolar organizer regions (NORs) were located at the telomeric regions of the short arms of three submetacentrics and two acrocentrics.

    Mitochondrial DNA control region variability of wild boar Sus scrofa with various external phenotypes in Turkey
    (Tubitak Scientific & Technical Research Council Turkey, 2016) Demirbas, Yasin; Ozkan Koca, Ayca; Pamukoglu, Nahit; Sert, Hakan; Suchentrunk, Franz
    The wild boar (Sus scrofa L.) is distributed across most parts of Turkey, a major biogeographic crossroads connecting Southwest Asia and Southeast Europe. However, no information on genetic diversity and population structure of this species in Turkey is available. In this study, we report on mtDNA sequence variability and phylogenetic relationships among wild boars with variable external phenotypes from both its European (Turkish Thrace) and Asian (Anatolia) distributions in Turkey. Phylogenetic analyses of mtDNA D-loop sequences (413 bp) of 53 newly sequenced wild boars from different localities in Turkey and 432 wild boar sequences from various geographic origins downloaded from GenBank were performed to particularly compare the phylogeographic position of wild boars from the European part of the Turkish range with that of specimens from Anatolia and to explore a possible phylogeographic substructuring in Anatolia. Relatively high genetic diversity was found in the Turkish samples, with a total of 17 haplotypes. Phylogenetic analyses revealed partitioning of the currently found Turkish haplotypes into two haplogroups, which were, however, only partially concordant with the geographic origins of samples (central and southwestern Anatolia vs. Turkish Thrace and northeastern and southeastern Anatolia). A median-joining network grouped most Turkish haplotypes with those previously reported from the Near East, whereas the remaining two haplotypes were included in the European 1 haplogroup. The combined phylogenetic analysis of the currently obtained sequences and all sequences retrieved from GenBank supported the earlier findings of four major haplogroups. The present study will serve as a baseline for more comprehensive studies to understand phylogenetic relationships of wild boars in Turkey and the Near East.
