    Electrophoretic characterisation of the venom samples obtained from various Anatolian snakes (Serpentes: Colubridae, Viperidae, Elapidae)
    (Editura Universitati din Oradea, 2008) Arikan H.; Göçmen B.; Kumlutaş Y.; Alpagut-Keskin N.; Ilgaz C.; Yildiz M.-Z.
    The venoms extracted from a colubrid snake [Malpolom monspessulanus (Hermann)], seven viperids [Montivipera xanthina (Gray), Montivipera wagneri Nilson & Andrén, Vipera ammodytes (Linnaeus), Vipera kaznakovi (Nikolsky), Vipera eriwanensis (Bonaparte), Vipera barani Böhme & Joger, Macrovipera lebetina (Linnaeus)] and an elapid snake [Walterinnesia aegyptia (Lataste)] collected from various regions of Anatolia were compared using polyacrylamide gel disc electrophoresis and densitometry analysis methods. The electrophoretic patterns (protein bands) of the examined venom snakes were demonstrated. The resulting electropherograms showed important qualitative differences amongst the colubrid snake Malpolon monspessulanus, the elapid species Walterinnesia aegyptia and the viperid snakes. In M. monspessulanus and W. aegyptia samples the total protein fraction numbers were 11 and 12, respectively, while in viperid samples the number was between 10 and 14, indicating a higher venom complexity in viperids compared to that of opistoglyph-colubrid and proteroglyph-elapid snakes. Electrophoretic data support the phylogenetic argument previously outlined for the family Viperidae. Moreover, it is concluded that the Macrovipera wagneri and Walterinnesia aegyptia are closely related taxa with front-fanged delivery systems in the light of protein band analogies.

    Genetic differentiation among peripheral populations of bombina bombina from Thrace and Anatolia: An allozyme analysis
    (2010) Alpagut-Keskin N.; Cevik E.I.; Arikan H.
    Genetic structures of Bombina bombina populations, located as peripheral isolates in Turkish Thrace and northwestern Anatolia, were analyzed by polyacrylamide gel electrophoresis using 20 allozyme loci, to investigate the populations' current genetic variation and possible colonization history. Significant genetic variability was detected in most of the loci and all populations. Allozyme pairwise F ST matrices and distribution of allele frequencies indicate their very close genetic relationships and relatively recent formation. Mean genetic distance values between Thracian and Anatolian populations indicate a Middle or Upper Pleistocene lineage separation before the formation of the Bosporus as an isolating geographic barrier. All the samples show substantial heterozygosity excess, and there was statistically significant evidence of recent bottlenecks. The extent and patterns of genetic divergence indicate that the Anatolian and Thracian populations have probably experienced bottlenecks, and incipient speciation may have occurred in Anatolian populations of B. bombina. © 2009 Springer Science+Business Media, LLC.

    Taxonomic Review of the Genera Nalassus Mulsant, 1854 and Turkonalassus gen. nov. of Turkey (Coleoptera: Tenebrionidae)
    (Muzeum i Instytut Zoologii, 2017) Keskin B.; Nabozhenko M.; Alpagut-Keskin N.
    A brief review of the genus Nalassus Mulsant, 1854 of Turkey is given. The new genus Turkonalassus gen. nov. (type species Helops adimonius Allard, 1876) is described. Species of the newly described genus are superficially similar to representatives of the subgenus Pelorinus of Probaticus (subtribe Helopina), but belong to the subtribe Cylindrinotina and are close to the genus Nalassus from which they differ by the absence of temple grooves ventrally (lower aspect of eye without ventral groove). The following species are included in Turkonalassus: Turkonalassus adimonius (Allard, 1876) (from Probaticus), Turkonalassus pentheri (Reitter, 1905), comb. nov. (from Probaticus), Turkonalassus bozdagus Keskin et Nabozhenko, 2010, comb. nov. (from Nalassus), Turkonalassus pineus sp. nov., Turkonalassus quercanus sp. nov., Turkonalassus petrophilus sp. nov., Turkonalassus macedonicus sp. nov. The last species is described from Greece and Bulgaria, the other species are known from Turkey. A new synonymy is established: Nalassus Mulsant, 1854 = Helopocerodes Reitter, 1922, syn. nov.; Turkonalassus pentheri = Cylindronotus hoberlandtii Kaszab, 1959, syn. nov. Lectotype of Helops pentheri Reitter, 1905 is designated. A key to the species of the genus Turkonalassus and genus Nalassus from Turkey is given. © Museum and Institute of Zoology PAS.
