Öğe Bibliography of Turkish bats (Mammalia: Chiroptera)(1999) Albayrak, İrfan; Aşan, Nursel; Pamukoğlu, Nahit…Öğe C-banded karyotype and NORs of the long-eared hedgehog, Hemiechinus auritus from Turkey(Inst Vertebrate Biology As Cr, 2009) Arslan, Atilla; Albayrak, İrfan; Pamukoğlu, Nahit; Yorulmaz, Tarkan; Toyran, KubilayThe karyotype, C-banding, and nucleolar organizer regions (NORs) of six specimens of Hemiechinus auritus from Turkey were examined. The diploid number of chromosomes was 2n = 48, the fundamental number of chromosome arms FN = 96, and the number of autosomal arms FNa = 92. Most of the chromosomes possessed centromeric constitutive heterochromatin, except of the pairs nos. 4, 6, 7, 8, 9, 12. and 17. The X and Y chromosomes appeared to be euchromatic. and possible geographic variation in their morphology was indicated in comparison with Previously published data. The NORs were located in the terminal regions of the long arms of four metacentric or submetacentric chromosomes. The localization of the NORs was not associated with C-positive autosomal regions as in hedgehogs of the genus Erinaceus.Öğe C-Banded Karyotype of Myocastor coypus (Molina, 1782) from Turkey (Mammalia: Rodentia)(Polish Acad Sciences, 2009) İlker, Ayşegül; Arslan, Atilla; Pamukoğlu, Nahit; Albayrak, İrfanThe present study reports the C-band patterns of chromosomes of Myocastor coypus fromTurkey. The karyotype of M. coypus is comprised of (2n) 42 chromosomes. the number of chromosomal arms (FN) was 83 and the number of autosomal arms (FNa) was 80. The X chromosome was a medium-sized metacentric and the Y chromosome was acrocentric and the smallest in the set. Two metacentric chromosomes have secondary constrictions. Most autosomes in this species were centromeric C-positive and some autosomes had telomeric C-bands. The X chromosome has centromeric heterochromatin, while the Y chromosome appeared to be entirely heterochromatic.Öğe Hair Morphology Examination of Badger Meles Meles (L., 1758) in Turkey By Using Light And Scanning Electron Microscopes(2020) Atasever, Didem; Pamukoğlu, NahitIn this study, the hairs of the badger (Meles meles) in the collection and various museums were examined and was tried to determine whether there were variations. For the morphological analysis of the guard hair samples taken from the middle part of the ridge, the guard hairs were examined by both light microscopy and scanning electron microscopy (SEM). The root of the guard hairs on the back and sides was dirty white, the body was brownish black and the tip was white. The length of the hairs on the back and sides was determined to be about 75 mm. It was determined that 21 of the samples had summer fur, the dorsal part had brown and transition tones had dark brown hairs, and 4 had winter fur, the dorsal part had grayish brown hairs and the ventral part had blackish light brown hairs. In addition, winter fur was found to be covered more frequently and with long guard hairsÖğe Investigation of Glutathione S-Transferase-Alpha and Glutathione S-Transferase-Pi Expression Levels in Spermophilus xanthoprymnus and Meriones tristrami in Terms of Living Conditions and Natural Habitat Differences in Kırıkkale Province(2023) Pamukoğlu, Nahit; Oğuztüzün, Serpil; Dirican, Onur; Sarıaltın, Sezen YılmazGlutathione S-transferase (GST) is a multifunctional enzyme that provides homeostasis by catalyzing the first step in the formation of the end product mercapturic acid in the detoxification metabolic pathway. Being found in mammals, insects, fish, birds, annelids, molluscs, and many microorganisms, GST takes part the elimination of toxic substances taken into body by consuming food, and their transport by binding non-substrate ligands (e.g. heme and bilirubin) with GSH. In addition, it can prevent reactive electrophilic compounds from harming the body by covalent bonding similar compounds to each other. These xenobiotic acceptors affected by GST include nitrogen halogen compounds, organophosphates, and polycyclic aromatic hydrocarbons. Xenobiotics are oxygenated by this enzyme system, the next mechanism of oxygenated products is more oxygenation, and these products become more easily soluble in water. In this study, Glutathione S-Transferase was detected in the liver tissue of Spermophilus xanthoprymnus and Meriones tristrami and its characteristic features were determined. For this purpose, the animals were anesthetized with sodium pentobarbital and their liver tissues were harvested. After necessary preparations were completed, the samples were analyzed by using immunohistochemical staining method and the expressions of GST isozymes were determined. As a result, glutathione s-transferase-alpha and glutathione s-transferase-pi expression levels were found to differ in Spermophilus xanthoprymnus and Meriones tristrami samples obtained from different localities of Kırıkkale province. Differences in GST enzyme expression in these species indicate that both species differ in their detoxification capacity and response to xenobiotics.Öğe Mitochondrial DNA control region variability of wild boar Susscrofa with various external phenotypes in Turkey(2016) Demirbaş, Yasin; Özkan, Ayça Koca; Pamukoğlu, Nahit; Sert, Hakan; Suchentrunk, FranzThe 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.Öğe The Taxonomy and Ecology of Meles Meles (L., 1758) in Western Turkey(2014) Pamukoğlu, Nahit; Albayrak, İrfanIn this study 21 specimens were collected from various localities to investigate the ecology and taxonomy of Meles meles in Western Turkey. Apart from these 28 badger specimens obtained from various collections were also used in the study. It has been recorded that the badgers live mainly in agricultural areas as well as bushy and forest areas and woodlands. They were found to feed on both animal and herbal food. The age groups of the specimens were determined. The morphological features and meauserements of the baculum were given. The taxonomic data of the adult specimens were compared with the badger specimens recorded from the palaearctic region and it was found that the collected specimens represented in nominative form.
