Öğe Banded karyotype features of the Bitlis chromosome race (2n=54) of nannospalax xanthodon (Nordmann, 1840) (Rodentia: Spalacidae) in Türkiye(Inst Zoology, Bas, 2023) Arslan, Atilla; Gözütok, Serdar; Toyran, Kubilay; Yorulmaz, TarkanNannospalax xanthodon has five chromosome races of 2n=54 in Tiirkiye. Until now, only C-banding and Ag-NOR staining analyses of Knikkale specimens of Yozgat chromosome race have been performed. In this study, we presented the karyotype characteristics of the Bitlis chromosome race with C-banding and Ag-NOR staining analyses. The numbers of bi-armed chromosomes in set of this race were found to be nine pairs and the numbers of acrocentric chromosomes were 16 pairs. This result is compatible with data on the previously studied Tatvan specimen. However, the Y chromosome of our specimens is different from that of the Tatvan specimen of this race. The Y chromosome is medium-sized subtelocentric (NFa=70). The dark centromeric C-bands were observed in all bi-armed and some acrocentric autosomes. The X chromosome had a centromeric band, while the Y chromosome was stained C-negative. The active NORs were determined in the telomeric regions of the short arms of two autosomes. The distribution pattern of the centromeric positive C-bands was generally similar between the Bitlis and Yozgat races. However, there were no C-heterochromatic short arms in the Bitlis race. The number and position of active NORs in both races were different.Öğe Bartın İlindeki Memeli (Classis: Mammalia) Türleri ve Korunma Durumları(2022) Gözütok, SerdarBartın ilinin doğal çevrelerinde bulunan Mammalia sınıfına mensup türlerin tespit edilmesi için yapılan bu araştırma 2016-2017 yılları arasında gerçekleştirilen arazi çalışmaları ve literatür değerlendirilmelerini kapsamaktadır.

All specimens examined revealed similar karyotypes comprising 60 chromosomes in the diploid complement. All autosomes and the X chromosome were acrocentric. The subtelocentric Y chromosome was recorded in M. anatolicusbut it was acrocentric in the other species. Dark C-bands were observed in centromeric/pericentromeric areas of all the acrocentric autosomes. The X chromosome had a centromeric C-positive area and the Y chromosome was completely heterochromatic in all specimens examined. AgNORs were recorded in the pericentromeric region of seven autosome pairs in M. irani karamani, ten autosome pairs in M. schidlovskii, and eight autosome pairs of M. anatolicus. Differences in the NOR distribution between the species were quantified in a neighbor-joining tree. The individuals of M. anatolicus appeared as the basal branch in relation to the derived sister group of M. schidlovskii and M. irani karamani.Öğe Comparison of the morphometric characteristics of some species of the genus Microtus Schrank, 1798 (Mammalia: Rodentia) in the Central Anatolia Region of Turkey(2020) Gözütok, Serdar; Albayrak, İrfanThe aim of this study was to determine and compare some morphometric characteristics of Microtus species occurring in the central Anatolia, Turkey. This study is based on 209 specimens of Microtus spp. collected the central Anatolia between 2003 and 2010. Some features concerning pelage coloration, cranial characters, tooth morphotype, and baculum morphology of the species were recorded to determine and evaluate their taxonomic characteristics. It was determined that four species of the genus Microtus occur in the study area, including Microtus dogramacii, Microtus guentheri, Microtus hartingi, and Microtus mystacinus. Microtus hartingi has been found to be widespread throughout central Anatolia. Microtus guentheri is located in the type locality and nearby provinces. M. guentheri and M. hartingi were not found to be sympatric. Among species, M. hartingi has the longest hind foot and M. mystacinus has the longest tail. The UPGMA trees were constructed for each sex, using skull and external measurements of Microtus specimens. As a result, M. dogramacii and M. guentheri being the most similar, and M. mystacinus is the sister species to these. But, it was determined that M. hartingi is distinctively from the these species.Öğe Distribution of constitutive heterochromatin and nucleolar organizer regions (NORs) in Mustela nivalis Linnaeus, 1766 (Carnivora, Mustelidae) in Turkey(Firenze Univ Press, 2015) Baydemir, Nursel Aşan; Demirbaş, Yasin; Gözütok, Serdar; Karöz, Ayşe MerveC- and Ag-NOR banding of the least weasel, Mustela nivalis, from the central and Mediterranean regions of Turkey was examined for the first time in this study. The chromosome set was composed of 18 biarmed and three acrocentric autosome pairs. The X chromosome was a medium-sized submetacentric, while the Y was a small metacentric. A distinct secondary constriction was observed on the juxta centromeric region of the long arm of an autosome that was negatively C-banded. Large heterochromatic C-blocks, stained densely, were detected in six biarmed pairs, while ones stained faintly were recorded in four biarmed autosome pairs. Active NORs were located in the secondary constriction of the acrocentric autosome. The numbers of C-banded autosomes of Turkish specimens were similar to those reported previously from the Palearctic region.Öğe The karyotype of anatolian ground squirrel spermophilus xanthoplymnus (Bennett, 1835) (Rodentia: Sciuridae ) from two localities in Anatolia, Turkey(Inst Zoology, Bas, 2020) Arslan, Atilla; Toyran, Kubilay; Gözütok, SerdarThe standard karyotype and C-banding characteristics of six specimens of Anatolian Ground Squirrel Spermophilus xanthoprymnus (Bennett, 1835) collected in Gilintishane Province and Bitlis Province, Turkey. The karyotypc of the individuals from both localities contained 42 chromosomes and all the chromosomes were bi-armed. The arm number of autosomal chromosomes (NFa) was 80 and the fundamental number of chromosomal arms (FN) was 84. The X chromosome was medium-sized and submetacentric. The Y chromosome of Bitlis specimens was smallest and bi-armed, and the Y chromosome of Gumushane specimens was medium-sized and subtelocentric. All the autosomes and X chromosome of specimens from both localities possessed distinct centromeric or pericentromeric C-positive bands. An interstitial dark C-band was apparent also on the long arm of the submetacentric autosomal pair 4. However, submetacentric autosomal pair 4 was heteromorphic in the Bitlis specimens due to intrachromosomal translocation. The Y chromosome of Gumushane specimens had centromeric C-band and the Y chromosome of Bitlis squirels was entirely euchromatic.Öğe The karyotype of anatolian ground squirrel spermophilus xanthoprymnus (Bennett, 1835) (Rodentia: Sciuridae) from two localities in Anatolia, Turkey(Bulgarska Akademiya na Naukite, 2020) Arslan, Atilla; Toyran, Kubilay; Gözütok, SerdarThe standard karyotype and C-banding characteristics of six specimens of Anatolian Ground Squirrel Spermophilus xanthoprymnus (Bennett, 1835) collected in Gümüşhane Province and Bitlis Province, Turkey.

Its distribution area in Türkiye is seen as fragmented. In the present study, a new distribution record for Plecotus auritus (Linnaeus, 1758) from Bolu province is given. External characteristics, fur coloration, skull morphology, morphometric measurements, and some ecological characteristics of the specimen were also recorded. The greatest length of skull, condylobasal length, zygomatic breadth, skull height, and largest diameter of tympanic bulla values were measured as high when compared to the data of Plecotus auritus from Türkiye and Central Europe. It is noted that the species' diet includes Galleria mellonella from the order Lepidoptera. Additionally, call length (ms) (1.4-4.9 mean= 3.4), max. frequency (kHz) (28.8-62.4 mean= 39.9), min. frequency (kHz) (16.8-36.4 mean= 24.3), and peak frequency (kHz) (22.8-35.6 mean= 28.7) acoustic parameters of Plecotus auritus were determined. © 2023, ABADER (Adıyaman Bilimsel Arastırmalar Dernegi).
