    A new subspecies, Lyciasalamandra atifi oezi n. ssp. (Urodela: Salamandridae) from Gazipasa (Antalya, Turkey)
    (Centre for Biodiversity of Montenegro, 2016) Tok C.V.; Afsar M.; Yakin B.Y.
    In this study, a new subspecies of the Lycian salamander, Lyciasalamandra atifi oezi n. ssp., was described from Gazipasa (Antalya, Turkey). The Lyciasalamandra specimens collected in Doganca (Gazipasa, Antalya) are clearly distinguished from the known subspecies of L. atifi by the very small and few white flecks on the dorsal ground pattern or by the absence of the flecks in some specimens. The light coloration, which can be distinctly observed in front of, behind, and under the eye of L. atifi, is indistinct in the new subspecies, unlike the other subspecies. The body length was observed to be shorter than that of the nominate subspecies but close to that of L. a. bayrami. In juveniles, scattered black flecks are striking on the posterior parts of their parotoids and, unlike adults, denser small and white flecks are striking on top of the head as well as on the dorsum, the tail, and the extremities. In addition, scattered yellow flecks in different sizes and shapes are present on the dorsal tail.

    A new subspecies, Ophisops elegans budakibarani n. Subsp. (Sauria: Lacertidae) from Mut (Mersin/Turkey)
    (Universitatea din Oradea, 2017) Tok C.V.; Afsar M.; Yakin B.Y.; Ayaz D.; Çiçek K.
    This study describes a new subspecies of Ophisops elegans from vicinity of Mut, Mersin, Turkey and named Ophisops elegans budakibarani n. subsp. The new subspecies is distinguished from geographically the closest subspecies O. elegans basoglui, found in the south of its distribution, by having higher number of the longitudinal row of scales+plates at mid-trunk (SPM) and a characteristic venter coloration (whitish coloration instead of lemon yellow color in venter of both sexes during the breeding season) and from O. elegans centralanatoliae, found in the north of its distribution, by having lower number of SPM and a characteristic dorsum color-pattern (less distinct tile reddish-brown coloration in the temporal band, missing large blackish spots in the vertebral and paravertebral area). © 2017 Biharean Biologist, Oradea, Romania.

    Observation on defensive behavior of two salamandrids: Ommatotriton vittatus (Gray, 1835) and Triturus ivanbureschi Arntzen & Wielstra, 2013
    (Editura Universitaria Craiova, 2019) Yakin B.Y.; çiçek K.; Afsar M.; Tok C.V.
    Amphibians developed various defensive strategies in order to be protected from predators and increase their survival success. One of these behaviors is called "immobility", in which during threat of predator attacks, amphibians stand still and then curl their tails and heads inward to show the "threatening" body coloration to the predator. Here, we report two cases of defensive behaviours in Southern banded newt from Mersin (Southern Anatolia) and Balkan crested newt from Manisa (Western Anatolia) under terrestrial stages. © 2019 Editura Universitaria Craiova.

    A new subspecies of Ottoman viper, Montivipera xanthina (Gray, 1849), (Squamata: Viperidae) from Geyik Mountains, Mediterranean Turkey
    (Institute for Biodiversity and Ecology, 2019) Afsar M.; Yakin B.Y.; ÇIçek K.; Ayaz D.
    A new Ottoman viper subspecies, M. xanthina varoli n. subsp., is described from the higher altitudes of Gundogmus (Antalya). The new subspecies differs from the other M. xanthina populations by pholidosis; higher number of intercanthals and lower number of subcaudalia. Also, the whiteness between windings or spots on dorsum pattern were observed in new subspecies, similar to the southern populations. Furthermore, the spots on the ventrals became denser in the mid-body and forms darker colorization at the end of body of the males and the tail tips are yellowish-orange or light orange on both sexes. © 2020, Institute for Biodiversity and Ecology.

    Action Plan for the Conservation of Endemic Anatolian Meadow Viper, Vipera anatolica Eiselt & Baran, 1970 in Southwestern Anatolia
    (Istanbul University-Cerrahpaşa, 2021) Tok C.V.; Afsar M.; Yakin B.Y.; Cicek K.
    The Anatolian viper, Vipera anatolica Eiselt & Baran, 1970, is the rarest, critically endangered, and endemic species in the western Taurus Mountains, Antalya, Turkey. Here, we evaluated the current status, potential threats, and recommended necessary conservation measures for Anatolian meadow viper. We created some activities during the 5-year species conservation action plan implemented by the General Directorate of Nature Conservation and National Parks. We conducted 70-days extensive fieldworks between May and October 2016-2017 for determining the distribution, habitat characteristics, phenology, and population status of the species in the province of Antalya. We also interviewed locals and surveyed potential threats of Anatolian meadow viper. We detected only 10 specimens in the territory of the Ciglikara cedar forest reserve at altitudes between 1800 and 2300 m and only two specimens in the territory of Geyik Mountains at altitudes between 1600 and 1900 m. We determined the potential threats like habitat loss and degradation, quarry (especially for senliki subspecies), global climate change, illegal collecting, and willingly or accidentally killing of vipers. Major precautions to protect the species were determined as: (1) to establish protected habitat patches in the species' known distribution and to prohibit entrance and grazing activities, (2) to create alternative new habitats for reintroduction, (3) to plan long-term monitoring survey to obtain data on its ecology and population trends, (4) to start a captive breeding program, (5) to educate and raise awareness among locals to prevent illegal collecting, willingly or/and accidentally killing of specimens for the sustainability of Anatolian meadow viper. © 2021 Istanbul University-Cerrahpa?a.

    On the occurrence of the Pond Slider Turtle Trachemys scripta (Thunberg in Schoepff, 1792) from southwestern Turkiye
    (Department of Environmental Sciences, Arak University, 2023) Yakin B.Y.; Çiçek K.; Bayrakci Y.; Günay U.K.; Afsar M.; Ayaz D.; Tok C.V.
    Trachemys scripta is included among the 100 most invasive species worldwide. Since the first report on the presence of pond slider turtles from natural habitats in Türkiye, the distribution of this invasive species comprises almost thirty provinces. However, it spread to much wider sites than the regions determined until today. Besides, there is a lack of knowledge on which subspecies exist in the invaded habitats. Within this study, we presented the presence of two subspecies of the invasive alien slider turtle for the first time from the Reşadiye, Datça, Muğla, Türkiye. We also suggest certain precautions should be taken against slider turtles to contribute to preventing their invasion of our biodiversity. © 2023, Department of Environmental Sciences, Arak University.
